US wind, solar tripled over the past decade: analysis

At-a-Glance: 

The United States generated three times as much renewable electricity from the sun and wind last year in comparison to 2012, a new analysis has found. Seven states alone now produce enough electricity from these sources, as well as geothermal energy, to cover half of their consumption, according to an online energy dashboard. Read more in US wind, solar tripled over the past decade: analysis.

Key Takeaways:

  • Just five years earlier, none of the states mentioned— South Dakota, Iowa, North Dakota, Kansas, Wyoming, Oklahoma and New Mexico — had achieved this level of renewable energy progress.
  • Among the dashboard’s key findings was evidence that the U.S. produced enough wind energy to power 35 million typical homes in 2021 — or 2.7 times as much wind energy as in 2012. 
  • The U.S. also generated enough solar energy that year to power 15 million homes — or 15 times as much solar energy as in 2012, according to the dashboard. 
  • The dashboard found that the country now has nearly 4.7 gigawatts of battery storage, or 32 times as much as in 2012. This helps support the use of more renewable energy and keep the lights on during extreme weather events. 
  • California, Texas and Florida exhibited the most growth in solar power and battery storage from 2012 to 2021, while Texas, Oklahoma and Iowa ranked highest for wind power growth.

Path to 100% Perspective

The rise in renewables is a key step in the Path to 100%, and the numbers should continue to grow as the Inflation Reduction Act makes now a perfect time to invest in clean energy technology.

As mentioned in the article, the key to integrating renewable energy into the system is backup power– both thermal and storage. That’s because solar and wind are variable– you can’t always count on them to produce power at peak demand times.

A “Supercharge” Of Renewable Energy Development Is Taking Place Around Us

At-a-Glance: 

Incentives in The Inflation Reduction Act (IRA) will lower the cost of renewable energy in the U.S. dramatically over the next decade, according to analysis from the ICF Climate Center, a global consulting firm. They’ve deduced that the new US climate law will make clean energy projects easier to finance across the country, quickening the pace of the US energy transition.  For more read: A “Supercharge” Of Renewable Energy Development Is Taking Place Around Us.

Key Takeaways:

  • All of the technologies the authors of this report analyzed —  whether mature wind and solar or emerging battery, hydrogen, and carbon capture and sequestration (CCS) — would see double digit percentage declines. 
  • The IRA’s broad definition of energy storage for the ITC should help emerging alternatives to lithium ion batteries come to market, increasing the diversity of energy storage options, 
  • Hydrogen could see the biggest cost decline — a huge reduction anywhere from 52% to 67% — of any technology. Green hydrogen facilities that take advantage of the climate law’s tax credits could become cost-competitive with new natural-gas-powered facilities by 2030.
  • The authors assume within their projections that policymakers will address some sticky obstacles confronting clean energy projects, including “not in my backyard” (NIMBY) reactions and interconnection problems.

Path to 100% Perspective

A 100% renewable energy future in the United States is possible by 2050 if everyone works together, and the IRA definitely sets the stage for an influx of development. While increasing renewable energy sources, like wind and solar, the U.S. must also determine a plan to realistically phase out fossil fuel plants. Renewable sources can be intermittent, so battery technology will need to improve. Investing in technology like Wartsila’s flexible power plants, which can run on sustainable fuels like hydrogen, will also provide the dispatchability needed to ensure reliable power.

Historic $7B federal funding opportunity to jump-start America’s clean hydrogen economy

At-a-Glance: 

The U.S. Department of Energy is accepting applications for the $7 billion program to create regional clean hydrogen hubs (H2Hubs) across the country. The H2Hubs will be a central driver in helping communities across the country benefit from clean energy investments, good-paying jobs, and improved energy security. For more read: DOE Opens Bipartisan Infrastructure Law Funding Opportunity for Regional Clean Hydrogen Hubs and Releases Draft of DOE National Clean Hydrogen Strategy and Roadmap.

Key Takeaways:

  • Hydrogen is a versatile fuel that can be produced from clean, diverse, and domestic energy resources, including wind, solar, and nuclear energy, or by using methane while capturing resulting carbon to reduce emissions.
  • DOE also released a draft of the National Clean Hydrogen Strategy and Roadmap, which provides an overview of the potential for hydrogen production, transport, storage, and use in the United States and outlines how clean hydrogen can contribute to national decarbonization and economic development goals. 
  • For this initial funding opportunity launch, DOE is aiming to select six to ten hubs for a combined total of up to $7 billion in federal funding. 

Path to 100% Perspective

Renewable fuels, like hydrogen, will play a significant role in transitioning to a 100% renewable energy power system, especially as the market for these fuels continues to grow in the transportation and industrial sectors. Hydrogen-based sustainable fuels can be stored in large quantities and for extended periods at power plants for long periods of use, enabling clean capacity to be cost effectively scaled up according to the needs of grids.

 

 

How Clean Energy Kept California’s Lights On During A Historically Extreme Heat Wave

At-a-Glance: 

A two-week heat wave in California put the electric grid to an extreme test, but despite record demand the power stayed on, largely due to the fact that the state has gone all-in on clean energy technology like wind, solar, battery storage, and demand response. For more read: How Clean Energy Kept California’s Lights On During A Historically Extreme Heat Wave.

Key Takeaways:

  • Batteries played a critical role in keeping the grid running, and without them we would have experienced rolling blackouts. California has more than 3.2 GW of batteries supporting the grid, up from just 250 megawatts in 2020. These batteries typically provide four hours of energy, so that’s 150 times more energy from just two years ago. 
  • Customers also played a part, drastically reducing power usage after text alerts asked them to conserve power. This did help, but can’t be relied upon in every situation.
  • Renewable energy sources helped, too, but did need battery backup. Solar provided a consistent source of power during the day, but dropped off in the evening, when the demand increased. Wind did pick up in the evening. 
  • The state is racing to install more solar, wind, batteries, as well as transmission to connect all these new resources to the grid.

Path to 100% Perspective

It’s encouraging to hear that 10 states have already set decarbonization goals, but it isn’t enough. The Path to 100% will take support from everyone– from government and business leaders to private citizens. While the path isn’t the same everywhere, it includes some common steps, like increasing the use of renewables while incorporating storage and flexible power plants that can provide a source of energy backup when renewables like wind and solar are not enough. Without a plan to ensure firm, reliable power at all times, support of the energy transition could decrease.

 

 

NREL Study Identifies Opportunities & Challenges Of Achieving The U.S. Transformational Goal Of 100% Clean Electricity By 2035

At-a-Glance: 

A new report by the National Renewable Energy Laboratory (NREL) examines the types of clean energy technologies and the scale and pace of deployment needed to achieve 100% clean electricity, or a net-zero power grid, in the United States by 2035.

Key Takeaways:

  • Overall, NREL finds multiple pathways to 100% clean electricity by 2035 that would produce significant benefits, but the exact technology mix and costs will be determined by research and development (R&D), manufacturing, and infrastructure investment decisions over the next decade.
  • To achieve 100% clean electricity by 2035, new clean energy technologies will have to be deployed at an unprecedented scale. Modeling shows that wind and solar would need to supply 60% to 80% of generation. Getting there would require an additional 40–90 gigawatts of solar on the grid per year and 70–150 gigawatts of wind per year by the end of this decade – more than four times the current annual deployment levels for each technology.
  • Seasonal storage, like clean hydrogen-fueled combustion turbines, is important when clean electricity makes up about 80%–95% of generation. Achieving the needed amount of storage requires substantial development of infrastructure, including fuel storage, transportation and pipeline networks, and additional generation capacity needed to produce clean fuels.
  • Overall, NREL finds in all modeled scenarios that the health and climate benefits associated with fewer emissions exceed the power system costs to get to 100% clean electricity.

Path to 100% Perspective

Achieving ambitious decarbonization goals will require a reduction of reliance on fossil fuels and an increase in renewable energy. What will be critical to the transformation is a reliable source of energy when sources like wind or solar are not producing enough. The most economical long-duration storage is formed with green hydrogen-based sustainable fuels, such as hydrogen, ammonia, carbon neutral methanol and methane. These fuels can be used to generate electricity in flexible power plants. Such flexible power plants provide carbon neutral firm, dispatchable capacity to the grid at any time.

Sustainable fuels can be produced using a process called Power-to-Gas (PtG), which uses surplus solar and wind energy to produce renewable fuels, like synthetic methane and hydrogen. Hydrogen as a fuel is carbon-free and synthetic methane produced using carbon recycled from the air, is a carbon-neutral fuel.

 

1 In 3 Americans Live In State With 100% Clean Electricity Commitment

At-a-Glance: 

While only ten states in the United States have set 100% renewable energy goals, 1 out of every 3 Americans actually live in a state that has made some sort of clean electricity commitment. California accounts for the seemed disparity, since it’s home to so many people. Read more in 1 In 3 Americans Live In State With 100% Clean Electricity Commitment.

Key Takeaways:

  • Since it is home to 39.35 million people, 12% of the USA’s population of 329.5 million, California alone already puts us at 1 out of every 8 Americans.
  • These 10 states have made a clean energy commitment: California, Hawaii, New Mexico, Washington, Rhode Island, Maine, New York, Virginia, Oregon, and Illinois.
  • If you don’t live in a state with clean energy goals, Environment America writes, “Tell your governor to commit to 100% renewable.” Included at this link is a way to quickly and easily send a message to your governor pushing for a 100% renewable electricity commitment. 
  • in the private sector, a great source for encouraging and tracking commitments from companies around the world is RE100. RE100 reports that there are now 370+ companies that have 100% renewable commitments of some sort.

Path to 100% Perspective

It’s encouraging to hear that 10 states have already set decarbonization goals, but it isn’t enough. The Path to 100% will take support from everyone– from government and business leaders to private citizens.

DOE awarding $540 million to ramp up clean energy research

At-a-Glance: 

The United States Department of Energy (DOE) announced it will grant 54 universities and 11 national labs over $500 million to conduct research on clean energy technologies and low-carbon manufacturing, ranging from direct air capture to carbon storage and sequestration. The move comes on the heels of the passage of President Biden’s historic Inflation Reduction Act, which aims to significantly cut emissions by 2030. By 2050, Biden hopes to have a net-zero emissions economy. Read more in DOE awarding $540 million to ramp up clean energy research.

Key Takeaways:

  • “Meeting the Biden-Harris Administration’s ambitious climate and clean energy goals will require a game-changing commitment to clean energy — and that begins with researchers across the country,” said U.S. Secretary of Energy Jennifer M. Granholm in a statement. 
  • Carbon dioxide emissions resulting from fossil fuel use are a significant driver of climate change.
  • A large portion of the money, $400 million, will go towards establishing and maintaining 43 Energy Frontier Research Centers, while these projects will study multiple topics including energy storage and quantum information science. 

Path to 100% Perspective

This is a great commitment by the U.S. federal government to influence positive change. While many of the tools for decarbonization already exist, there are problems to overcome like how to create long-term energy storage. There is promise in Power-to-X technology, a carbon-neutral solution that uses renewable energy to produce green hydrogen and other future fuels that can be used for affordable long-term storage. It is exciting to see the outcome of the vast research resources now committed to this effort.

 

 

 

Utilities are planning to shift to clean energy — just not too quickly

At-a-Glance: 

CEO of electricity research group EPRI says U.S. utilities are poised to go big on solar, wind and batteries — but they aren’t ready to give up their gas and coal plants just yet.

“You will also hear every one of [these utilities] saying that if we don’t take care of affordability and reliability, that will be the biggest obstacle to go to clean energy, because if customers get upset, it will have a negative impact on the clean energy transition.” said Arshad Mansoor, CEO of the Electric Power Research Institute. Read more in Utilities are planning to shift to clean energy — just not too quickly

Key Takeaways:

  • At EPRI’s Electrification 2022 conference, leading utilities unanimously embraced cutting carbon emissions and electrifying transportation. However, they urged caution at moving too quickly.
  • Most utilities know this is the decade to invest in wind, solar and battery storage. They have determined that grids can handle levels of renewable generation that were previously unthinkable — in fact, this is already happening in many states.
  • The COVID pandemic came at the worst time, causing major delays in the supply chain and slowing the construction of renewable resources.
  • Mansoor feels it may be necessary to keep some coal plants around as backup power sources to ensure a reliable power source, because wind and solar power is not always reliable and battery technology is not yet capable of long-term duration.
  • He says clean firm resources such as small modular nuclear reactors or clean hydrogen-burning turbines could eventually take that role, as could cheap long-duration energy storage, but they’re all still years away.

Path to 100% Perspective

The Path to 100% agrees that the way to a 100% clean energy future is through increased renewable energy sources like wind and solar power while maintaining a reliable backup system. To balance the intermittent nature of these renewable power sources, engine power plants and energy storage are ideal. While we are waiting for battery storage to improve, Wartsila’s flexible power plants are already generating reliable, backup power when solar and wind are not enough. They are capable of powering up and down quickly, unlike traditional coal-powered thermal power plants which could take hours to ramp up when energy is needed.

 

 

Wärtsilä to supply Clearway with 500 MW/2 GWh of energy storage for projects in California and Hawaii

At-a-Glance: 

Wärtsilä has reached an agreement with Clearway Energy Group on a contract that will see it supply Clearway with a 500 MW/2 GWh portfolio of energy storage systems. The storage systems will be used across a series of solar and storage projects that Clearway is developing in California and Hawaii. The five-project portfolio includes 75 MWac/300 MWh located in Hawaii and 415 MW/1.7 GW in California. For more read: Wärtsilä to supply Clearway with 500 MW/2 GWh of energy storage for projects in California and Hawaii.

Key Takeaways:

  • In Hawaii, Clearway is developing the Mililani I Solar and Waiawa Solar Power facilities on the Island of Oahu and represent Wärtsilä’s first large-scale energy storage systems in the state. 
  • The addition of energy storage will help Clearway Energy Group ensure reliable delivery of sustainable energy and contribute to Hawaii’s goal of reaching 100% renewable energy generation by 2045.
  • In California, 482 MW of solar and 275 MW/1.1 GWh of energy storage are being split across the Daggett 2 and Daggett 3 projects, which are being developed in San Bernardino, California, adjacent to the site of a retired coal and natural gas plant.
  • The storage systems will deliver renewable energy during increasingly volatile peak periods and help the state reach its goal of 100% carbon-free electricity by 2045.
  • Each facility will include Wärtsilä’s GridSolv Quantum, a fully integrated, modular and compact energy storage system, as well as the GEMS Digital Energy Platform, Wärtsilä’s energy management platform for power system optimisation. 

Path to 100% Perspective

To achieve goals of both reliable and renewable energy, it is critical to think beyond solar panels and wind turbines. The addition of storage technologies is essential because both wind and solar technology is dependent on the weather. The storage system is one way to ensure there is enough power when the sun isn’t shining or the wind isn’t blowing. To take it one step further, power producers should also invest in flexible engines, capable of starting and stopping when needed to ensure a reliable energy supply.

$15 trillion global hydrogen investment needed to 2050-research

At-a-Glance:

Decarbonizing energy and other industries globally using hydrogen will require investment of almost $15 trillion between now and 2050, the Energy Transitions Commission (ETC) said in a report in April. The ETC is an international coalition of executives from the energy industry committed to achieving net zero emissions by mid-century, a goal set by the Paris climate agreement. To learn more, read “$15 trillion global hydrogen investment needed to 2050-research.”

Key Takeaways:

  • Hydrogen use is forecast to grow to 500-800 million tons a year by mid-century, accounting for 15-20% of total final energy demand, from 115 million tons currently.
  • Producing green hydrogen will need zero-carbon electricity supply to increase by 30,000 terawatt hours (TWh) by 2050, on top of 90,000 TWh needed for decarbonization generally, the ETC said.
  • Around 85% of the required investment would be in electricity generation and 15% in electrolysers, hydrogen production facilities and transport and storage infrastructure.
  • Large-scale geological storage will be needed for the hydrogen produced, given the limited capacity and large costs of compressed hydrogen containers. Salt caverns will offer the lowest cost but if 5% of total annual hydrogen use in 2050 needs to be stored, it needs about 4,000 typical size salt caverns, compared with only about 100 in use for natural gas today, the report said.

Path to 100% Perspective:

As coal, diesel and legacy natural gas plants are retired to achieve ambitious decarbonization goals, the need for new dispatchable capacity is necessary for reliability and resiliency in future power systems. Short-duration and long-duration energy storage are both necessary in future power systems and they each have different roles. Long-duration storage has been the missing piece of the decarbonization puzzle, however, the use of battery storage in this application is not economical or viable.

The most economical long-duration storage is formed with green hydrogen-based future fuels, such as hydrogen, ammonia, carbon neutral methanol and methane.These fuels can be used to generate electricity in flexible power plants. Such flexible power plants provide carbon neutral firm, dispatchable capacity to the grid at any time.

California duck curve “alive and well” as renewable, minimum net load records set

At-a-Glance:

High wind and solar production combined with low demand led the California Independent System Operator (CAISO) to reach a new record of 92.5% of load served by renewables and 98.1% of load served by carbon-free resources,CAISO reported. To learn more, read “California duck curve ‘alive and well’ as renewable, minimum net load records set.”

Key Takeaways:

  • The records were set on March 13. That same day,  CAISO established a new minimum net load, which is load minus wind and solar generation, 3.614 GW.
  • Wind generation averaged 22% of the total fuel mix on March 13, the highest daily average on record, according to CAISO data. That jump in wind generation drove wind and solar generation to a combined daily average of 39.2% of the mix, more than double the three-year average.
  • CAISO has made significant progress in working with the battery storage community to support system reliability during stressed operating conditions by establishing a minimum state of charge requirement that will be applied when day-ahead markets indicate the potential for insufficiency.
  • CAISO is also initiating longer-term market design work with storage providers to develop enhancements that will support system reliability while more effectively addressing the commercial and asset optimization needs of a diverse fleet of storage resources.

Path to 100% Perspective:

California has made impressive gains in its integration of renewables into the power supply mix. While these numbers are worth celebrating, there is much more work to do if the state is going to meet its 100% clean energy target by 2045. It is possible, and the Optimal Plan provides the

lowest transition costs by including flexible thermal generation. The flexible thermal generation assets can be converted as needed to use carbon-neutral fuels produced with excess solar and wind energy through Power-to-X, forming a large, distributed, long-term energy storage system.

An $11 trillion global hydrogen energy boom is coming. Here’s what could trigger it

At-a-Glance:

Storing fuel in salt caverns isn’t new, but hydrogen’s growing role in decarbonization has revitalized interest in the concept. The Advanced Clean Energy Storage project in Utah aims to build the world’s largest storage facility for 1,000 megawatts of clean power, partly by putting hydrogen into underground salt caverns. The concept is quickly gaining momentum in Europe. To learn more, read “An $11 trillion global hydrogen energy boom is coming. Here’s what could trigger it.

Key Takeaways:

  • With the cost of renewables such as 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 increase anywhere from 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 (NREL).
  • Bank of America believes hydrogen technology 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.

Path to 100% Perspective:

Hydrogen has a high potential of becoming the fuel of the future, helping societies move towards decarbonization. Because hydrogen was not used as a power generation fuel in the past, the technologies to combust and use it in different applications need to be developed. Hydrogen burns with air to produce water, without any carbon emissions. It is perfect for use in 100% clean energy portfolios.
