A little more context before I get into it.
Back in April, Jeff St-John of Canary Media reported that a massive green hydrogen hub in Utah wins $504M federal loan guarantee:
One of the biggest proposed green hydrogen projects in the U.S. has won a $504.4 million conditional loan guarantee from the U.S. Department of Energy’s Loan Programs Office, putting the $1-billion-plus project a step closer to building hundreds of megawatts of hydrogen production capacity in Utah.
The Advanced Clean Energy Storage (ACES) project, launched in 2019, plans to build 220 megawatts of electrolyzers that will use carbon-free electricity to convert water to up to 100
metric tons of hydrogen a day. That hydrogen will be stored in two
massive underground salt caverns near the town of Delta, Utah, capable
of storing up to 5,500 metric tons of hydrogen, or enough to generate 300 gigawatt-hours of electricity.
The ACES project is a joint venture of Mitsubishi Power Americas, a subsidiary of Japan’s Mitsubishi Heavy Industries that makes turbines and other energy industry equipment, and Magnum Development,
the owner of the salt caverns where the hydrogen is to be stored. These
are some of the only underground salt dome formations in the U.S.
outside of the Gulf Coast region. The salt domes in the Gulf Coast store
vast amounts of oil and fossil gas, including the U.S. Strategic Petroleum Reserve, and they’ve also been targeted for hydrogen production and storage.
In terms of its scale, ACES matches some of the bigger green hydrogen projects being developed in Europe, Australia and the Middle East. Haddington Ventures, financial adviser for the ACES project and equity sponsor of Magnum Development, is now securing $650 million in equity financing, according to Mitsubishi Power Americas’ Tuesday announcement.
Hydrogen produced in ways that limit or eliminate carbon
emissions could be a vital replacement for fossil fuels for
hard-to-decarbonize industries such as shipping, aviation, steelmaking and cement production. But ACES is targeting its initial green hydrogen production for another use: replacing fossil gas as a fuel to generate electricity.
ACES’ first customer will be the Intermountain Power Agency,
which operates a coal-fired power plant that supplies roughly half of
its electricity to municipal and cooperative utilities in Utah. The
other half goes to the far-off municipal utility Los Angeles Department
of Water and Power (LADWP).
The Intermountain plant is being converted to an 840-megawatt turbine designed to run on a blend of 70 percent natural gas and 30 percent hydrogen starting in 2025, with a plan to convert it to 100 percent hydrogen by 2040. That could provide LADWP with always-available carbon-free generation to help meet its goal of reaching net-zero carbon emissions by 2035.
Intermountain is one of the more advanced efforts to tap
hydrogen as an energy-storage resource for power grids that are
converting to carbon-free generation. One of the biggest challenges for
decarbonizing the grid is how to cover the gaps when solar and wind
power aren’t producing enough to meet electricity demand — including
days- or weeks-long lulls that utility-scale lithium-ion battery farms
can’t cost-effectively cover.
Utah produces less than 4 percent
of its electricity from renewable resources today. But PacifiCorp, the
Berkshire Hathaway Energy–owned parent company of Rocky Mountain Power,
Utah’s main investor-owned utility, is planning to build solar and wind power across its six-state territory, including Utah.
Why DOE’s Loan Programs Office is supporting green hydrogen
The DOE’s Loan Programs Office
has now conditionally approved three loans or loan guarantees since the
start of the Biden administration, and two of them have been for
hydrogen projects. The first was in December, when LPO conditionally approved a $1.04 billion loan to Monolith,
a company seeking to expand its Nebraska facility that uses renewable
energy to power a pyrolysis process that converts fossil gas to
hydrogen, which is initially intended for conversion to ammonia for
fertilizer production. Instead of emitting carbon into the atmosphere,
Monolith’s process yields a solid carbon byproduct that can be used in
industrial processes such as making tires.
DOE has made carbon-free hydrogen research, development and commercialization a major focus. The bipartisan infrastructure law passed last year includes $8 billion to fund four clean-hydrogen production hubs. It also directs $500 million to clean hydrogen demonstration projects and $1 billion to research advances in the electrolyzers that use electricity to split water into oxygen and hydrogen.
Jigar Shah, head of DOE’s Loan Programs Office, said in a Tuesday statement that making hydrogen via electrolysis using renewable electricity costs about $5
per kilogram today. That’s roughly four to five times the cost of
making hydrogen via steam reforming of methane from fossil gas, the
carbon-emitting process that currently produces the vast majority of the
world’s hydrogen, which is used primarily for refining, fertilizer
production and other industrial processes. The aim of the new loan
guarantee for the ACES hub is to help bring that $5-per-kilogram price point down to about $1 per kilogram, the target that DOE has set with its Hydrogen Shot program.
Using hydrogen to decarbonize heavy industry, transport and
energy generation will dramatically increase global demand for
cost-effective production at much larger scales than today. “While
industries are beginning to implement clean hydrogen to reduce
emissions, many hurdles remain for deploying it at scale,” Shah said in
the statement.
LPO’s mission
is to provide loans or loan guarantees to lower the cost of capital for
technically proven but underdeveloped technologies ranging from
renewable energy, electric vehicles, batteries and battery materials to transmission grids, carbon-capture systems and nuclear power.
Shah has said that the U.S. must scale up its “climate-change solutions deployment” investment from about $200 billion a year today to closer to $1 trillion per year to meet the Biden administration’s goal of halving economywide carbon emissions from 2005 levels by 2030.
The International Energy Agency has projected that the world will need about 850 gigawatts of electrolyzer capacity by 2030 to stay on the narrowing pathway to net-zero carbon emissions by 2050. The ACES project represents less than one-quarter of 1 percent of that global target — an indication of the enormity of the investment needed in the decade ahead.
Also in April, Sonal Patel of Power Magazine reported on how ACES Delta’s giant Utah salt cavern hydrogen storage project gets $504M conditional DOE loan guarantee:
The Advanced Clean Energy Storage Project, a
much-watched project under development in Delta, Utah, that is shaping
up to be the largest renewable hydrogen energy hub in the U.S., has
garnered a conditional commitment for a $504.4 million loan guarantee
from the Department of Energy’s (DOE’s) federal loan guarantee program.
The conditional loan guarantee commitment issued on April 26 is for the Advanced Clean Energy Storage I, the first phase of a massive undertaking by ACES Delta, which is a joint venture comprising Magnum
Development (Magnum), Mitsubishi Power, and Haddington Ventures, to
create a new pathway for decarbonization of the Western U.S. grid.
The project envisions producing up to 100 metric tonnes per day of hydrogen from water and renewable energy sources using a 220-MW alkaline electrolyzer bank manufactured by Norwegian firm HydrogenPro—one of the largest deployments of its type to date. That hydrogen will be stored in two gigantic solution-mined caverns sited in the only salt dome in the Western U.S.
Capable of storing a combined 300 GWh of
energy, the storage facility will provide long-term seasonal energy
storage to Intermountain Power Plant’s (IPA’s) Intermountain Power Plant
(IPP) near Delta, Utah, a coal-fired plant that is slated to be repowered with two Mitsubishi Power advanced M501JAC power trains as an 840-MW combined cycle power plant by 2025.
A Power-to-Power Project
The 1986–opened IPP’s two
coal-fired units, a combined 1,800 MW, currently average about 13 TWh
each year, power that is delivered over 2.4-GW AC and DC lines to IPA’s
35 municipal utility participants, which are primarily in Utah and
Southern California. Catering to state clean energy targets—including
California’s 100% clean electricity target by 2045—IPA in 2019 signed a pioneering contract with Lake
Mary, Florida–based Mitsubishi Power Americas that commercially
guarantees the M501JAC units will be able to combust a mix of 30%
hydrogen and 70% natural gas when they come online in 2025. Mitsubishi
Power told POWER that progress continues to develop a second-generation combustion system that will enable the JAC units to achieve 100% hydrogen fueling by 2045.
The DOE’s Loan Programs Office (LPO) lauded the project’s selection for its potential to “safely and cost-effectively produce and store hydrogen.” LPO Director Jigar Shah on April 26 noted the selection, which is just one of nearly 80 active applications across
a variety of technology sectors submitted to the DOE office since March
2021, supports the Biden administration’s efforts to tamp down
renewable hydrogen costs by about $5/kilogram as well as “expand the use
of clean hydrogen in the industrial sector and beyond.”
The ACES Delta project becomes the
DOE’s third offered conditional loan guarantee under the Biden
administration. LPO in December offered a $1 billion conditional loan guarantee to Monolith,
a 2012-established firm that has developed a methane pyrolysis process
to convert natural gas into hydrogen and high-purity carbon black using
renewable energy. On April 18, it offered to
conditionally lend up to $107 million to Syrah Technologies to expand
its capacity to produce critical materials for lithium-ion batteries at
the Syrah Vidalia Facility in Louisiana.
Shah on Tuesday highlighted the ACES
Delta project’s potential to reduce curtailment of renewable energy in
the Western U.S., as well as reduce criteria air
pollutant emissions, such as ozone precursors and particulate matter,
as well as greenhouse gases (GHGs). That’s consistent with the primary
goal of the Title XVII Program, which was established in the 2005 Energy
Policy Act, the DOE noted.
“Financially supporting the Project would
help bring hydrogen to market and into greater use, thereby reducing
overall national emissions of air pollutants and human-caused GHGs,” it
added. However, while the conditional commitment demonstrates the DOE’s
intent to finance the project, “several steps
remain, and certain conditions must be satisfied before the Department
issues a final loan guarantee,” Shah noted on Tuesday.
A Massive and Urgent Undertaking
According to Michael Ducker, senior vice
president of Hydrogen Infrastructure for Mitsubishi Power Americas and
president of Advanced Clean Energy Storage I, the project (which is
referenced by its full name for trademarking reasons) has made rapid
progress since its unveiling in May 2019. Since
the project was unveiled, ACES Delta has set out to obtain necessary
state and local permits and approvals for the project, as well as
prepare the project design and cost estimate. The DOE assessed these
factors as it made its conditional commitment, Ducker noted.
The ACES Delta project is now in the
final stages of debt and equity closing. While Haddington Ventures, the
financial advisor for the project and equity sponsor of Magnum
Development, is securing $650 million through its Equity Syndication
Program, ACES Delta expects financial close of the loan guarantee in the
second quarter of 2022, Ducker said.
The hub has also secured all major
contracts, including for offtake with IPA, engineering, procurement, and
construction (EPC) contractors, as well as major equipment suppliers
and operations and maintenance (O&M) providers. Engineering giant
Black & Veatch is slated to provide EPC services, while Mitsubishi
Power will provide all hydrogen equipment integration, including the 220
MW of electrolyzers, gas separators, rectifiers, medium voltage
transformers, and distributed control system. NAES Corp., an O&M
service firm, will initially provide the O&M services for the plant
and will oversee the current projected team of 20 plant-related
personnel. WSP, another engineering giant, will provide EPC management
services for the development of the two large salt cavern storage
facilities, leveraging decades of experience in its development of more
than 200 salt caverns around the world.
Construction Has Begun
These milestones, reached with
extraordinary speed for such a massive project, have already allowed
ACES Delta to break ground at the project site. “Construction has
begun,” Ducker confirmed. “That’s because we’re keeping with the
schedule at IPA and the other online date for their power plant, for the
hydrogen-capable gas turbines in 2025,” he said.
This year, IPA plans to begin upgrading the IPP with Mitsubishi Power’s M501JAC
gas turbines, heat recovery steam generators, and steam turbines in
each of the plant’s combined-cycle units. In tandem, Mitsubishi Power’s “multi-cluster” combustor technology
that could enable 100% hydrogen combustion at the project’s heavy-duty
JAC gas turbines is under validation and will be commercialized at the
newly unveiled Takasago Hydrogen Park
in Japan. “To sync up schedules with us constructing the caverns and
the hydrogen production, we need to start now,” Ducker noted.
Construction of the Advanced Clean
Energy Storage project will entail building a hydrogen generation
facility, where the electrolyzers will produce and compress hydrogen for
delivery and storage in the caverns. The electrolyzers from HydrogenPro
(a company in which Mitsubishi Power’s parent company Mitsubishi Heavy Industries (MHI) is an investor) will be housed in above-ground mechanical units with low-profile cooling towers and other associated facilities.
The project also includes the construction of ancillary support facilities, such as the O&M building; an electrical distribution and high-voltage transmission system with a substation and switchyard facilities; water and brine delivery systems with pumps, filtration, and pipelines; standard water treatment facilities to provide demineralized water for the electrolysis modules; demineralized water storage tanks; raw water tanks for process water; firewater storage
tanks; cooling towers to support rejection of heat generated during the
process; plant instrumentation; and a hydrogen gas delivery system with
filtration and dehydration units and quality and flow measurement facilities.
The most time-consuming task within the
project construction scope, however, relates to building the two
caverns, which are purpose-built and engineered to store hydrogen. The
salt dome sprawls over 4,800 acres directly adjacent to the IPP power
plant near Delta, Utah. The two storage caverns envisioned as part of
the first phase of the Advanced Clean Energy Storage Project will be built about a mile away from the electrolyzers.
“In accordance with the geo-mechanical design, the dimensions of each cavern are anticipated to be approximately 220 feet in diameter and approximately 1,200 feet in height. The tops of the caverns will range in depth between 3,500 and 4,100 feet below the ground surface (bgs), and the bases of the caverns
will range in depth from 4,700 to 5,300 feet bgs,” the LPO’s
environmental assessment (EA) for the Advanced Clean Energy Storage
Project says.
“A salt cavern takes roughly two years to
construct,” Ducker said. “The best way to think about that site is as a
big block of salt. What we do is drill into that salt with conventional
drilling practices,” he explained. “It’s literally just drilling a well
down, and then we inject water. Water dissolves salt, and then based on
where we put the ‘stringer,’ you basically keep dissolving the salt,
bringing that water out, putting new fresh water in.” The caverns will
require large evaporation ponds that will contain brine solution. But
the technique, while slow, is deliberate, Ducker noted. It “entails no
exotic materials,” he said. It’s “literally just time and water.”

The LPO’s EA suggests the project is designed with features that
include “equipment and material selection appropriate for the hydrogen
gas generation and handling process.” These include minimum distances
between certain hydrogen generation and handling equipment, the
installation of a facility-wide leak detection and emergency shutdown
system, and emergency and fire response and suppression measures. A
Safety in Design (SID) analysis and preliminary Process Hazard Analysis
(PHA) were also completed for the project’s front-end engineering
design. “The analyses were completed to determine the applicable
regulatory requirements for preventative design features and measures and active and passive fire protection systems to incorporate into the facility design,” the EA says. A final PHA will also be completed as part of the final facility design.
Hydrogen Hub Part of a Larger Vision
Completion of the first phase of the
Advanced Clean Energy Storage project will inform future phases, as well
as provide more insight on future infrastructure needs for a potential
expansion. “We really see this as the first
phase of our hub, and so over time, we’re looking to add additional
projects,” Ducker said. “Some may be for power applications and
long-duration storage, like we’ve got for [the first phase]. They may be
for other heavy industries.”
Ducker said that while ACES Delta has
focused on “getting this first piece done,” developers have envisioned
what the whole site could look like through the next several decades. A
“2050 vision” plan, for example, projects that up to 70 caverns, each of
which could store up to 5,500 metric tonnes of hydrogen, “would be
necessary to help support the arbitrage and storage that’s across all
verticals, not just power,” he said. “It’s looking at heavy industries
and everything else.” The site itself can support up to 100 caverns,” he
noted, which could “adequately support” the entire 2050 needs for
hydrogen in the West.
Millard County, a sparsely populated basin and range area
within the Sevier Desert in western Utah, is notably cultivating an
energy project cluster that could ultimately support the Advanced Clean
Energy Storage hydrogen hub’s role in a wider scale effort to
decarbonize the West, or provide crucial regional reliability. Magnum,
for example, has received approval from the Federal Energy Regulatory
Commission (FERC) for a gas storage project that would include the
construction and operation of a natural gas storage facility, along with
a 62-mile-long natural gas header pipeline. A construction schedule is
as of yet undetermined, however.
FERC notably also recently prepared a
final environmental impact statement for another pipeline project, the
Delta Lateral Project, Kern River Gas Transportation Co.’s proposed 36-mile-long pipeline, which could deliver a firm 140,000 dekatherms of natural gas per day from Opal, Wyoming to the IPP.
IPP has said it will use the new pipeline to provide the natural gas
that it will initially use to generate power. Finally, Energy Capital’s
300-MW ECG Utah Solar 1 Project, is slated to be completed by 2024, potentially transmitting power to the IPP.
But according to Ducker, the ACES Delta
project shines for its unique potential, which is to serve as a crucial
demonstration for technology integration, with a minimal technology
risk, of an end-to-end solution to produce, store, and convert renewable
hydrogen for the Western U.S. The project’s regional significance has
been heralded by the Western Green Hydrogen Initiative,a
network of 11 western states and two Canadian provinces (along with
Florida, Ohio, and Louisiana), whose mission is to scale renewable
hydrogen production and use while avoiding costly transmission
build-out.
The overall project, whose costs have been estimated at $1 billion,
will offer a valuable service, Ducker added. “We really don’t look at
this as on a dollar-per-kilogram basis because it’s just like with
batteries,” he said. “When you’re looking at lithium-ion batteries, you
don’t think about it as a fuel, you think about it as storage,” he
noted. “So when we look at the overall project, at least as ACES has
assessed it, we see the ability for the overall decarbonization goals at
a 20% lower cost of electricity than if hydrogen long-duration energy
storage weren’t in the mix.”
The project, Ducker predicted, will be
competitive. “When we look at the production costs—if we break out just
the production piece or salt cavern piece—it is competitive with today’s
technologies, and what’s been put out there already,” he said.
What else? Back in 2020, Tim Hornyak of CNBC reported that an $11 trillion global hydrogen energy boom is coming., here’s what could trigger it. I note this part:
The Advanced Clean Energy Storage (ACES) project
aims to build a storage facility for 1,000 megawatts of clean power,
partly by putting hydrogen into underground salt caverns. Last year,
Mitsubishi Power, a maker of gas turbines, and Magnum Development, which
owns salt caverns for liquid fuel storage, announced the project will
combine technologies such as renewable hydrogen, solid-oxide fuel cells,
and compressed air energy storage.
The storage facility would initially have enough energy to power
150,000 households for one year. Scheduled to be operational by 2025,
the first phase of the Advanced Clean Energy Storage project will
provide 150,000 MWh of renewable power storage capacity, nearly 150
times the current U.S. installed lithium-ion battery storage base,
according to Mitsubishi Power.
The project will also help address a
problem with renewable energy production: fossil-based energy must be
used immediately because grids lack storage capacity, which can mean curtailment
of renewables in times of low demand. Having large-scale renewable
energy reserves on tap can accelerate the shift to clean power. If
former Vice President Joe Biden is elected president next month, he may funnel up to $1.7 trillion over 10 years into measures to boost renewables and accelerate the adoption of electric vehicles.
Green hydrogen is hydrogen produced with renewable power and zero emissions. With the cost of renewables like solar power falling,
green hydrogen is being touted as one part of the energy mix that will
lead toward decarbonization, with applications ranging from consumer and
industrial power supplies to transportation and spaceflight. By 2050,
U.S. demand for hydrogen could jump to 22 million to 41 million metric
tons per year, up from 10 million today, according to a study released this month by the U.S. Department of Energy’s National Renewable Energy Laboratory.
After
decades of false starts, hydrogen technology is poised to take off as
falling production costs, technological improvements, and a global push
toward sustainability converge, according to Bank of America. The firm
believes this will generate $2.5 trillion in direct revenue — or $4
trillion if revenue from associated products such as fuel cell vehicles
is counted — with the total market potential reaching $11 trillion by 2050.
Major firms such as BP, Siemens Energy, Shell and Air Liquide
are interested in green hydrogen production, but part of the challenge
is where to store energy so it can be ready when needed. That’s where a
project like Advanced Clean Energy Storage can help.
Making holes in the ground
“California
curtailed between 150,000-300,000 MWh of excess renewable energy per
month through the spring of 2020, yet saw its first rolling blackouts in
August because the grid was short on energy,” says Paul Browning, CEO
of Mitsubishi Power Americas. “Long-duration energy storage projects
like ours that are designed to shift excess energy from periods of
oversupply, like California in the spring, to periods of undersupply,
like California in late summer, are critical to ensure similar events
are avoided as we continue to make significant strides towards deep
decarbonization.”
Storing fuel in salt caverns isn’t new, but
hydrogen’s growing role in decarbonization has revitalized interest in
the concept. The U.S. Strategic Petroleum Reserve has long stored
emergency crude oil in underground salt caverns on the Gulf Coast,
and notes they cost 10 times less than aboveground tanks and 20 times
less than hard rock mines. The Reserve has 60 enormous caverns,
typically 200 feet in diameter and 2,500 feet tall, and one “large
enough for Chicago’s Willis Tower to fit inside with room to spare.”
Caverns
can be created in salt domes by drilling into the salt dome and
injecting the rock with water, which dissolves the salt. The resulting
brine is extracted, leaving a large cavity. The next step is storing
hydrogen in the cavern. Hydrogen electrolyzers can convert water into
hydrogen by using renewable energy from solar and other sources. The
hydrogen can then be stored, and reconverted to electricity when needed.
In
the Advanced Clean Energy Storage project, some will power the adjacent
Intermountain Power Project, a coal-fired plant operated by the Los
Angeles Department of Water and Power that will be converted to hydrogen
and natural gas, which produces almost half the carbon dioxide of coal,
by 2025. It’s scheduled to be all green hydrogen by 2045. If the
initial phase of the project is successful, the salt dome’s vast
capacity could be exploited further.
“The formation has the potential to create up to 100 caverns, each one
capable of holding 150,000 MWh of energy,” says Browning. “It would take
40,000 shipping containers of batteries to store that much energy in
each cavern.”
I am providing my readers with a good background to really understand and appreciate the scale and scope of this project and why this is another great investment on energy transition which AIMCo, OTPP, GIC and Manulife are all taking part of.
Once completed, the green hydrogen storage hub near Delta, Utah, will have an electrolyzer
capacity to produce up to 100 metric tonnes per day of green hydrogen under a long-term
contract with the Intermountain Power Agency (IPA), which is comprised of 23 Utah municipalities
and owns the Intermountain Power Project (IPP).
The key here is what John Strom, Managing Director of Haddington Ventures, states:
“This is a pivotal investment for western states seeking to meet their aggressive decarbonization
goals. The ACES Delta hub will
be larger than any existing green-hydrogen production and storage site by a factor of 10, which
is the scale needed for electric utilities. The project uniquely leverages readily scalable
electrolyzer technologies with multiple large salt dome storage caverns to make a meaningful
environmental contribution.”
Scaling an existing green-hydrogen production and storage site by a factor of 10 needed for electric utilities is no easy feat.
In fact, if you read this 2020 report from the International Renewable Energy Agency (IRENA), Green Hydrogen Cost Reduction: Scaling Up Electrolysers to Meet 1.5°C Climate Goal, you will gain a deeper appreciation of what is involved.
From the Executive Summary:
Importantly, the largest single cost component for on-site
production of green hydrogen is the cost of
the renewable electricity needed to power the
electrolyzer unit:
This renders production of green
hydrogen more expensive than blue hydrogen,
regardless of the cost of the electrolyser. A
low cost of electricity is therefore a necessary
condition for producing competitive green
hydrogen. This creates an opportunity to produce
hydrogen at locations around the world that have
optimal renewable resources, in order to achieve
competitiveness.
But that's not enough. The report also states up to 85% of green
hydrogen production costs can be reduced in the
long term by a combination of cheaper electricity
and electrolyzer capex investment, in addition to
increased efficiency and optimized operation of
the electrolyzer.
The report also states this:
Gaps in cost and performance are
expected to narrow over time as innovation
and mass deployment of different electrolysis
technologies drive convergence towards similar
costs. The wide range in system costs is expected
to remain, however, as this is very much dependent
on the scale, application and scope of delivery. For
instance, a containerised system inside an existing
facility with existing power supply is significantly
lower cost than a new building in a plot of land to
be purchased, with complete water and electricity
supply system to be included, high purity hydrogen for fuel cell applications and high output
pressure. Normally, numbers for system costs
include not only cell stack, but also balance of
stacks, power rectifiers, the hydrogen purification
system, water supply and purification, cooling and
commissioning – yet exclude shipping, civil works
and site preparations.
Anyway, there is a lot of technical jargon in this report but it's well worth reading it here to understand how costs of producing green hydrogen are coming down.
Another report worth reading is this one here from the Global Infrastructure Investor Association (GIIA)
on Catalysing Hydrogen Investment.
GIIA is a membership body representing the
leading investors and advisers in global infrastructure and it includes many of the largest Canadian pension investment managers, including AIMCo and OTPP.
Here is the Foreword from Lawrence Slade, CEO of GIIA:
And read the introduction and first few pages:
Interestingly, the report states:
While green hydrogen dominates discussions about electrolysis-based
pathways, nuclear-powered production also holds promise. Nuclear
power plants produce electricity and heat in a stable manner, which
means that they can be paired with electrolysers (e.g. solid oxide) that
operate at high temperatures and provide increased efficiencies. The
baseload nature of nuclear power also means that the electrolysers
can operate most of the time, improving the economics over those
connected to intermittent supplies from renewables. Moreover, the
nuclear option can provide production at gigawatt-scale. However, the
sector is heavily regulated, so developing a nuclear hydrogen plant
concept is likely to take years and the high capital costs of nuclear
plants will also pose a challenge to competing with other production
pathways.
And on storage, I note this:
There are various things that need to be considered when studying
hydrogen as an energy storage option, including the scale and capital
cost of the storage receptacle as well as the operating costs and energy
losses in the associated processes. These depend on the scale and
technology used to convert the hydrogen back to electricity, e.g. fuel
cells, gas turbines, combustion engines or boilers.
The main drawback of using hydrogen for electricity storage is the
relatively large amount of energy that is wasted at each stage of the
thermodynamic cycle. The “round trip efficiency” of the cycle refers
to the amount of useful electricity ultimately generated divided by the
total energy required to produce, store and reconvert the hydrogen.
For hydrogen, the round trip efficiency can be in the order of 30%
depending on the application, whereas for lithium-ion batteries, the
charge/discharge cycle is about 85-90% efficient.
There are multiple other types of energy storage technologies
available as well, including pumped hydro, compressed or liquefied
air storage, flywheels, supercapacitors and others. Considering the
possible competition, investments that rely heavily on revenues
from balancing demand and supply on the electricity grid need to be
considered very carefully. The associated technology risks are likely
to remain high.
Anyway, take the time to read the entire report here, it is truly excellent
and well worth reading why investors are increasingly honing their
attention on hydrogen (blue, green, yellow, pink and grey).
In this comment, I am just provided you with a glimpse of why hydrogen is a hot topic among investors and why this investment by AIMCo, OTPP, GIC and Manulife into the ACES Delta hub is well worth tracking as this looks like the future of hydrogen storage.
In
addition to the investors’ $650 million initial capital commitment, they
have additional rights to increase their collective investment to $1.5
billion.
Ben Hawkins, Head, Infrastructure, Renewables & Sustainable Investing AIMCo is very clear:
“We firmly believe that green hydrogen will play a key role in decarbonization in the US, where
long-duration storage will be essential for the higher penetration of renewable power, and to
meet fluctuating inter-season power demand. As a long-term investor, we are pleased to partner
with this strong group of likeminded developers and equity partners to position ourselves well for
the growing hydrogen economy.”
And so is Chris Ireland, Managing Director, Greenfield and Renewables at Ontario Teachers’:
“We’re proud to be investing in one of the largest and most advanced green hydrogen projects
in the U.S.. Ontario Teachers’ is committed to decarbonization and the energy transition and we
believe green hydrogen production and storage will play an essential role in this transition. We
see the ACES Delta platform as the beginning of a long-term partnership with a top-quality
developer.”
"We have done a lot of work around climate change and energy transition.
We want to be investment led, we think our energy department is going
to expand by more than 50% over the coming decades. And so, we are not
going to turn off our lights, the heating and stop traveling, It's going
to be a massive transition in terms of the structure of the economy.
So, there's a lot of uncertainty. We don't have all the answers but in
those circumstances where the landscape is going to change meaningfully,
there is lots of uncertainty. That means the reward for good hard
research and due diligence is more pronounced and there will be plenty
of opportunities but there will also be plenty of risks around that. For
us at AIMCo, how do we capture and navigate those opportunities and
risks in a very proactive, investment led manner. This will be pivotal
to our success. So we are spending more time in this space looking at all kinds of things like hydrogen, storage, carbon capture, etc."
You would expect Alberta's pension fund to be very much honed into what is going on across traditional and new forms of energy, it only makes sense.
Alright, let me wrap it up there.
