U.S. Energy Secretary Jennifer Cronhome has announced a goal to reduce grid-sized energy storage costs by 90 percent in the United States over the next 10 years.
The ambition of the U.S. Department of Energy (DOE) is set in the long-term deficit shot, which is part of the Energy Earth Shot initiative. The long-term shortage shot is aimed at storing clean electricity and making an improvement that is available anywhere at any time.
Hundreds of gigawatts
“In the coming years we will put hundreds of gigawatts of sustainable energy into the phase so that we can use that energy where and when needed,” Cronhome said. That is why my ministry is actively working on cheap, long-term energy storage to achieve President Biden’s goal of 100 percent clean electricity by 2035. This new initiative will create new manufacturing jobs locally and ensure clean, unreliable and affordable electricity for all.
The output of long-term energy storage — defined as systems that can save more than 10 hours at a time — can support a low-cost, reliable, carbon-free power grid. Inexpensive and highly efficient storage makes it easier to capture and store clean energy when power is not available or when it is in short supply – Cranholm says – for example, allowing solar power to be used at night or when nuclear power is low when demand increases.
