Pacific Northwest Set to Launch Hydrogen Energy Hub

 PNNL News Release:

PNNL research team helps define hydrogen’s role in the new energy economy of the Pacific Northwest

October 13, 2023

RICHLAND, Wash.—The Department of Energy today announced $7 billion to launch seven regional clean hydrogen hubs (H2Hubs) to develop clean hydrogen energy that meets the nation’s energy needs. The regional hydrogen hubs will establish a national clean hydrogen network over the next decade.   Realizing this goal requires the expertise and experience of a true multi-sector partnership. DOE’s Pacific Northwest National Laboratory is lending its expertise across several fields of study to support the Pacific Northwest Hydrogen Association (PNWH2). Public and private groups represented in PNWH2 are working with leaders in Washington, Oregon and Montana to leverage the region’s renewable energy sources to produce clean hydrogen for the region.   “Unlocking the full potential of hydrogen—a versatile fuel that can be made from almost any energy resource in virtually every part of the country—is crucial to achieving President Biden’s goal of American industry powered by American clean energy, ensuring less volatility and more affordable energy options for American families and businesses,” said Secretary of Energy Jennifer M. Granholm. “With this historic investment, the Biden-Harris Administration is laying the foundation for a new, American-led industry that will propel the global clean energy transition while creating high quality jobs and delivering healthier communities in every pocket of the nation.”   Clean hydrogen energy impact PNNL’s Daniel Gaspar, serves as a senior technical advisor to the PNWH2 consortium.   “It’s important to evaluate the carbon impact of hydrogen production from the moment it’s produced to the moment it’s used, or what’s called cradle-to-gate emissions,” said Gaspar, a PNNL chemist with expertise in clean hydrogen and sustainable fuels. “PNNL is helping the Pacific Northwest projects determine their life-cycle impacts, including a framework to measure other impacts besides greenhouse gas emissions.”   PNNL experts are also providing economic analyses and evaluations of hydrogen production, integration with the electrical grid, and other areas as the region builds out a clean hydrogen economy.   “We are fortunate to be able to leverage existing clean, renewable electrical power in the Pacific Northwest to produce hydrogen at scale,” Gaspar added. “With our abundant Pacific Northwest hydroelectric power providing renewable electricity, we see clean hydrogen produced from clean electricity as being critically important to getting to net zero for greenhouse gas emissions in the heavy-duty transportation sector and other hard-to-abate applications.”   PNNL has a track record of working with regional partners to explore the feasibility of using clean hydrogen as a renewable energy source in a decarbonized energy economy. For example, PNNL researchers previously assisted partners at the Port of Seattle and Seattle public utility, Seattle City Light, to study the use of hydrogen at the Port.

Going forward, PNNL scientists, engineers and analysts are providing ongoing support to the PNWH2 consortium as they make progress toward lowering the cost of producing hydrogen in the Pacific Northwest and expanding its use in hard-to-abate sectors.   DOE’s H2Hubs will kickstart a national network of clean hydrogen producers, consumers and connective infrastructure while supporting the production, storage, delivery and end-use of clean hydrogen. Funded by President Biden’s Investing in America agenda, the H2Hubs will accelerate the commercial-scale deployment of clean hydrogen—helping generate clean, dispatchable power, create a new form of energy storage and decarbonize heavy industry and transportation. Together, they will also reduce 25 million metric tons of carbon dioxide) emissions from end-uses each year—an amount roughly equivalent to combined annual emissions of 5.5 million gasoline-powered cars—and create tens of thousands of good-paying jobs across the country while supporting healthier communities and strengthening America’s energy security.

Floating Offshore Wind Could Bring Billions in Value to the West Coast, Report Shows

 PNNL News Release:

Researchers modeled the performance of hypothetical floating wind farms off the coast of southern Oregon and northern California, showing multiple futures in which the benefits outweigh the cost of development.

October 11, 2023

RICHLAND, Wash.—A new report from Pacific Northwest National Laboratory shows that along a 200-mile stretch of ocean off the coast of southern Oregon and northern California, floating wind farms could potentially triple the Pacific Northwest’s wind power capacity while offsetting potentially billions of dollars in costs for utilities, ratepayers, insurance companies, and others across the West who bear the cost of climate change’s effects.   “This research is all about unlocking an untapped source of supply where there is limited transmission and little ability to move that electricity today,” said Travis Douville, lead author on the report and an advisor at PNNL who leads research on integrating wind energy into the grid. “Offshore wind offers a massive opportunity to decarbonize the western United States.”   The nation’s power supply is split into three separate grids, with the western interconnection providing power to more than 80 million people over 14 states in the western United States and two Canadian provinces. The new report dives into future scenarios where floating offshore wind farms are connected to the shore between Coos Bay, OR, and Eureka, CA, via large transmission lines—and the value those wind farms could bring to utilities and ratepayers alike.   The benefits of offshore wind Land-based wind farms across the United States already produce more than 140 gigawatts of energy, contributing to about 10% of the nation’s energy portfolio. Currently, the federal government aims to install 30 gigawatts of offshore wind by 2030 and to increase that number to 110 gigawatts of offshore wind by 2050. That much wind power could power tens of million of homes and cut more than 78 million metric tons of carbon emissions.   One of the perks of offshore wind turbines—whether they’re attached to the ocean floor or floating on the surface—versus land-based is that wind over the ocean is less variable and more consistent, said Mark Severy, a research engineer at PNNL and coauthor on the report. Wind over land is generally more variable because it may be influenced by the complex relationship between the atmosphere and landscapes like mountains, valleys, flat plains, or forests.   Wind over the ocean also tends to peak in the evenings, which could help supply power when solar energy dips as the sun sets, Severy said. In places like California, where solar energy makes up most of the renewable power, utilities could turn to wind power in the evenings, when demand generally goes up, instead of fossil fuels to power homes.   Modeling floating offshore wind energy To meet the nation’s ambitious wind power goals, potential offshore wind farms must be carefully studied and planned. And along with building floating wind turbines in the ocean, researchers will also have to figure out how to bring the power they generate to land and connect it with the electrical grid.   One challenge is determining whether already existing transmission infrastructure could support incoming energy from offshore wind. In a previous study, Douville and other researchers found that offshore wind could supply 3 gigawatts of energy with upgrades to Oregon’s current transmission lines. That’s enough energy to power 1 million homes.   But what about in the future, with more transmission lines and an increased ability to transport energy? “How do you harness offshore wind energy in a way that allows you to adequately, reliably, and resiliently supply electricity in the future at lowest cost?” Douville said. “And what is the role of transmission design to influence the value of offshore wind?”   To find out, the team modeled different transmission scenarios, two of which represent a future where offshore wind farms and new, powerful transmission lines add an additional 20 gigawatts worth of wind power to the western interconnection. Both scenarios include high-voltage direct current (HVDC) transmission lines to carry power, which would then be converted to alternating current (AC) once onshore (DC can transmit higher voltages and thus more energy, but needs to be converted to AC to be distributed to the end users).   The two scenarios differ in whether each wind farm is connected separately to shore (in a radial structure) or whether the wind farms are connected to each other, then to shore (a backbone structure).   Although both transmission scenarios offered millions of dollars in value, the backbone structure offers slightly different benefits, Severy said. In the radial scenario, power can only go to one place—wherever the wind farm is connected on the coast—and then distributed from there. In the backbone structure, power can be diverted up and down the coast.

In their investigation of the economic benefits of floating offshore wind, researchers looked at two different ways that the generated power could be delivered to shore. One was a radial structure, in which individual wind farms (represented by a single wind turbine in the above image) are each connected to shore where power is delivered.

The second structure is called a backbone, in which the wind farms are connected to each other, then connected to shore at fewer points.

For example, “in times when there's excess solar generation in California, we found that the backbone provides another pathway for that electricity to go to the Pacific Northwest and when there is a lot of hydropower in the Pacific Northwest, the backbone is another pathway south, outside of the congested transmission lines on the I-5 corridor,” Severy said.   Although either option would be expensive, “the benefits exceed the costs in nearly every scenario,” Douville said. In those scenarios where benefits exceed the costs, the values of the various returns on investment range between $127 million to $6 billion. These numbers represent savings to produce and supply power as well as avoided cost of the effects of air pollution and destruction wrought by climate-change-related disasters.   Challenges for offshore wind development Douville stressed that many more questions need to be answered before an offshore wind plan can be executed. Many of these questions will come into focus on the West Coast Offshore Wind Transmission Study, which kicked off in May 2023 and aims to determine how the nation can expand transmission to harness offshore wind power on the West Coast.   For instance, researchers and policymakers need to consider how transmission lines will fare underwater. Sea floor depth and slope could affect where cable could be laid, and salt water can be very corrosive, said Jason Fuller, chief energy resilience engineer at PNNL. Maintenance could be tough, depending on how deep the cables are laid. In addition, the nation simply hasn’t used HVDC as much as AC on the grid, and modeling HVDC with current tools can be difficult. PNNL researchers are working on modeling the performance of HVDC lines to support the offshore wind work.   Researchers and policymakers will also have to consider other stakeholders who depend on the ocean, including fisheries and other coastal communities.   “Early coordinated transmission planning leads to more economical solutions, for utilities, ratepayers, and society as a whole,” said Douville. “If we plan now for what we think the grid will look like 20 years from now, and policymakers can use these insights to guide development, we're going to end up with a better solution.”   This work was funded by the National Offshore Wind Research and Development Consortium and the Bureau of Ocean Energy Management.

Report Highlights Technology Advancement and Value of Wind Energy

 Berkeley Lab News Release:

New dynamics expected in the years ahead as deployment and supply chains expand

Wind energy continues to see growth, solid performance, and attractive prices in the U.S., according to a report released by the U.S. Department of Energy (DOE) and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab).  With levelized costs averaging under $40 per megawatt-hour (MWh) for newly built projects, the cost of wind is well below its grid-system, health, and climate value. “Wind energy prices – particularly in the central United States – remain attractive even with ongoing supply chain and inflationary pressures,” said Ryan Wiser, a senior scientist in Berkeley Lab’s Energy Technologies Area. “Considering the health and climate benefits of wind energy makes the economics even better,” he added.   Though 2022 was a relatively slow year for new wind power deployment, the Inflation Reduction Act promises new market dynamics in the years ahead. Key findings from DOE's annual “Land-Based Wind Market Report” include the following:  • Wind comprises a growing share of electricity. U.S. wind power deployment totaled 8.5 gigawatts (GW) in 2022, representing a $12 billion investment. Wind energy contributed more than 10% of the nation’s electricity supply, and as much as 38% in the Southwest Power Pool. A record-high 300 GW of wind is seeking transmission interconnection. • Wind turbines continue to get larger as technology advances. Improved plant performance over the last decades has been driven by larger turbines mounted on taller towers and featuring longer blades. In 2012, only 1% of turbines employed rotors that were 115 meters in diameter or larger, while 98% of newly installed turbines featured such rotors in 2022. Proposed projects indicate that total turbine height will continue to rise. • Wind energy prices have risen, but remain attractive for purchasers. Wind power purchase agreement prices have been drifting higher since about 2018, with a recent range from below $20/MWh to more than $40/MWh depending on region and other details. These prices, which are possible in part due to federal tax support, are similar to recent solar sales prices and to the projected future fuel costs of gas-fired generation.  • The grid-system value of wind surged in 2022 across many markets. The value of wind sold in wholesale power markets is affected by the location of wind plants, their hourly output profiles, and how those characteristics correlate with real-time electricity prices and capacity markets. The market value of wind generally increased in 2022, driven higher by high natural gas and wholesale power prices. The highest wind values were in New England and California (above $75/MWh), with the lowest values in the Southwest Power Pool ($18/MWh). • The average levelized cost of wind energy was $32/MWh. Levelized costs vary across time and geography. The national average stood at $32/MWh for wind plants built in 2022, driven lower by the concentration of new wind projects in the nation’s lowest-cost wind regions: Texas and the central part of the country. (Cost estimates do not count the effect of federal tax incentives for wind.) • The health and climate benefits of wind in 2022 far exceeded the levelized cost of wind. Wind generation reduces power-sector emissions of carbon dioxide, nitrogen oxides, and sulfur dioxide. These reductions, in turn, provide public health and climate benefits that vary regionally, but together are economically valued at an average of $135/MWh in 2022. • The domestic supply chain began 2022 in decline, but passage of the Inflation Reduction Act created renewed optimism. Though domestic manufacturing of towers and nacelles was strong in 2022, blade manufacturing has plummeted in recent years. The Inflation Reduction Act contains, for the first time, production-based tax credits for domestic manufacturing of key wind components like nacelles, towers, and blades; it also extends the tax credit for wind deployment, inclusive of a new 10% bonus for projects that meet domestic content requirements. Consequently, there have been at least eleven announcements of manufacturing facilities that plan to open, re-open, or expand to serve the land-based wind industry. • Energy analysts project growing wind deployment, spurred by incentives in the Inflation Reduction Act. The Inflation Reduction Act provides a long-term extension of tax credits for wind energy along with opportunities for wind plants to earn two 10 percent bonus credits. The average wind deployment forecast for 2026 among analysts is 18 GW, a significant increase from the 11 GW 2026 forecast from a year ago (before the Inflation Reduction Act).   Berkeley Lab’s contributions to this report were funded by the U.S. Department of Energy’s Wind Energy Technologies Office.

Railways Could Be a Key 'Utility Player' for Backup Power

 Berkeley Lab News Release:

Berkeley Lab researchers demonstrate trains can cost-effectively dispatch grid-scale batteries in emergencies

– By Christina Nunez The U.S. electric grid faces simultaneous, evolving pressures. Demand for power from the grid is increasing as people adopt electric cars and building energy is transitioned from gas to electricity. At the same time, climate change is driving more extreme weather. Events like the 2020 heat wave that led to rolling blackouts in California are relatively infrequent, but they are happening more often – and utilities need to be ready for them. New research points to a flexible, cost-effective option for backup power when trouble strikes: batteries aboard trains. A study from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) finds that rail-based mobile energy storage is a feasible way to ensure reliability during exceptional events. Previous research has shown that, in theory, rail-based energy storage could play a role in meeting the country’s daily electricity needs. Berkeley Lab researchers wanted to take this idea further to see whether rail-borne batteries could cost-effectively provide backup power for extreme events – and whether the scenario was feasible on the existing U.S. rail network. “There’s a lot of uncertainty around when extreme supply shortfalls are going to happen, where they will happen, and how extreme they may be,” said Jill Moraski, a graduate student at the University of California Berkeley, a researcher at Berkeley Lab, and the paper’s lead author. “We found that the U.S. rail network has the capacity to bring energy where it’s needed when these events happen, and that it can cost less than building new infrastructure.” The paper, “Leveraging rail-based mobile energy storage to increase grid reliability in the face of climate uncertainty,” was published recently in the journal Nature Energy. A Ready Resource in Freight Rail The idea for the study came to Amol Phadke, a Berkeley Lab staff scientist and co-author of the study, while he was watching a long freight train trundle past at a railway crossing. He began counting the cars and tallied over 100 on that single train. “A thought then struck me – how many batteries could such a massive train carry? If those were used for emergency backup power, how significant would their contribution be?” Phadke writes in a briefing on the study.” A quick, back-of-the-envelope calculation revealed an astounding capacity, potentially sufficient to provide power to every household in Berkeley for a few days.” To meet electricity demand and build capacity for backup power, the U.S. is building long-distance transmission lines and installing stationary banks of batteries. “While both of these resources are necessary, we wanted to explore additional, complementary technologies,” said Natalie Popovich, a Berkeley Lab research scientist and co-author of the study. “We have trains that can carry a gigawatt-hour of battery storage, but no one has thought in a cohesive way about how we can couple this resource with the electric grid.” The U.S. rail network is the largest in the world, covering nearly 140,000 miles (220,000 kilometers). The study looked at historical freight rail flows, costs, and scheduling constraints to see whether railroads could be summoned to transport batteries for high-impact events, given that grid operators typically have at least a few days’ notice, and sometimes up to a week, when extreme weather is coming. The analysis found that mobile energy storage could travel between major power markets along existing rail lines within a week without disrupting freight schedules. What About Stationary Options? The researchers compared the cost of deploying batteries on rail for low-frequency events with the investment costs of stationary energy storage and transmission lines. In cases where the trains need to cover distances of about 250 miles (400 kilometers) or shorter – roughly equivalent to a trip from L.A. to Las Vegas – rail-based energy storage could make more sense cost-wise than building stationary battery banks to fill supply gaps that happen during less than 1% of the year’s total hours. At those shorter distances, transmission lines remain cost-effective compared to batteries on rail if they are used frequently. When the travel distance grows to more than 930 miles (1,500 kilometers) – say, a trip from Phoenix to Austin – rail becomes cheaper than transmission lines for low-frequency events. This third option could save the power sector upwards of 60% of the total cost of a new transmission line or 30% of the total cost of stationary battery storage, the study concludes. The study points to New York State, with its robust freight capacity and current transmission constraints between upstate clean energy generation and downstate load centers, as an example of where rail-based mobile energy storage could work well. In other cases, it may make sense for multiple states to share the additional capacity from a rail-based battery bank. “This is not necessarily a resource that needs to be in one region,” Moraski said. “It can operate similar to an insurance policy, where you spread the coverage across risks for a wide geographic region.” A Train of Thought Worth Following Regulatory and infrastructure hurdles exist, the authors note. The U.S. lacks adequate interconnections to take power off the train and essentially plug it into the grid. And current electricity markets have no framework for approving, pricing, and regulating a mobile energy asset the way they do for conventional power plants. Policies would need to be revised, and efforts to deploy the storage would need to capitalize on existing interconnections where possible, such as retiring coal plants, which have existing rail lines and interconnection rights. The researchers see further opportunities to quantify the benefits of rail-based mobile energy storage beyond the scope of the current study, taking into account larger territories, a decarbonized grid, and future climate conditions. They emphasize that extending energy storage across the rail network is not a replacement for important infrastructure such as transmission lines, but could be an important complement. “Our paper gives a top-level overview of how rail-based mobile energy storage could benefit today’s grid, in today’s climate,” Moraski said. “As we look toward a future with more electrification, more fluctuating renewable energy, and more frequent extreme events, the case for adding rail-based energy storage to the mix may become even stronger.” This research was funded by the William and Flora Hewlett Foundation.
