US Department of Energy: In 2030, long-term energy storage technology must achieve large-scale commercial operation

　　According to reports, a spokesperson said at a panel meeting held by the U.S. Department of Energy (DOE) that a plan is being prepared for accelerating research on the durability and performance of long-term energy storage systems. This is a key step in achieving the decarbonization goal set by the US government.

　　The US Department of Energy stated that by 2030, long-term energy storage technology must achieve large-scale commercial operations to increase the share of renewable energy in the grid and achieve the US goal of adopting 100% clean electricity by 2035.

　　Most energy storage projects have been used for at least 15-20 years, which means that even energy storage developers and operators cannot verify the actual performance of their entire life cycle before 2030. Eric Hsieh, director of grid systems and components for the US Department of Energy, said that the US Department of Energy has proposed a Rapid Operation Verification Program (ROVI) to accelerate testing and validate long-term energy storage technologies more quickly.

　　Long-term energy storage systems are widely deployed and are defined as energy storage systems that operate continuously for at least 10 hours. The U.S. Department of Energy announced a plan in July to reduce the cost of utility-scale long-term energy storage systems by 90% within ten years, supported by federal incentives.

　　In a speech at a conference held by the Department of Energy, David Turk, the Deputy Secretary of the U.S. Department of Energy, said that the introduction of long-term energy storage systems into the grid can not only use more renewable energy, but also improve grid resilience and reduce energy burdens. Provide assistance to disadvantaged communities.

　　Although breakthroughs have been made in the technology of long-term energy storage (especially the 100-hour iron-air battery announced by Form Energy in July), experts warn that in the real world, for long-term energy storage systems The time for testing is limited.

　　Craig Horne, general manager of the energy storage business of California-based Wellhead Electric Company, said in a speech at the group meeting that the limited amount of data for long-term energy storage systems in terms of performance and production may hinder their deployment. He said that power suppliers need to have confidence in the way these long-term energy storage systems operate, no matter how their technology evolves and develops.

　　The Rapid Operation Verification Program (ROVI) is an initiative proposed by the National Laboratory of the US Department of Energy, which aims to model the performance of different long-term energy storage technologies through the use of machine learning and artificial intelligence, including predicting how the energy storage technology will be Loss or maintains the original performance over time.

　　Brentan Alexander, CCO and CSO of insurance agency New Energy Risk, said that these data can give power suppliers more confidence in the reliability of long-term energy storage technology, thereby helping to reduce the soft cost of installing energy storage systems. This is especially important considering the long-term operation of the energy storage system and the possibility of being forced to endure unpredictable weather conditions.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries, and are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.
