Energy Secretary Rick Perry hailed energy storage Thursday, describing it as the “holy grail” of energy. The Trump administration, however, doesn’t share Perry’s enthusiasm for the technology, based on its budget request to Congress.
The Department of Energy’s (DOE) energy storage program would see its budget cut by 61 percent — from $20.5 million to $8 million — under President Donald Trump’s fiscal year 2018 budget proposal. The administration’s lack of interest in funding energy storage, though, hasn’t stopped Perry from touting its value.
“The holy grail of energy … is about battery storage,” Perry said Thursday at an event in Washington, D.C., hosted by Axios and NBC News. “Battery storage changes the world, I would suggest, the same way that hydraulic fracturing and directional drilling has changed the world.”
DOE’s energy storage program is housed in its Office of Electricity Delivery and Energy Reliability, whose budget would plunge from $230 million to $120 million under Trump’s proposed budget. A House-passed appropriations bill, however, would set funding for the office at $219 million for the fiscal year.
DOE’s storage program performs research and development on a wide array of storage programs, including solid state batteries, flow batteries, flywheels, and compressed air. Gigawatt-scale grid storage would improve the transmission and distribution system, resulting in lower future investments necessary to ensure grid stability. One of the barriers to lowering the cost of energy storage is that public research and development spending in energy storage has slowed down, even as reliable electric power delivery has become a higher priority.
