WASHINGTON — Assistant Energy Secretary Bruce Walker said Thursday that the Department of Energy is planning a megawatt-scale “Storage Launchpad” that he predicted will cut the cost of energy storage dramatically.
Walker told attendees of the NERC Reliability Summit that funding for the initiative, which will be assigned to one of DOE’s 17 National Laboratories, is included in President Trump’s proposed fiscal 2020 budget, which was released March 11.
“We are going to build a facility … where we can leverage our focus on chemistry. So we’re looking at aqueous, non-aqueous redox equation-type batteries, zinc manganese oxide,” Walker said. “We’ve made some significant breakthroughs already in that space. We believe we’re going to be able to drive the cost down to basically 20% of what it is today over the next five years.”
The budget proposes $5 million for the Storage Launchpad and $15 million “to accelerate the conversion of the National Wind Testing Facility site into an experimental microgrid capable of testing grid integration at the megawatt scale.” The budget would cut funding for DOE’s Office of Energy Efficiency & Renewable Energy by 70% and eliminate the Advanced Research Projects Agency-Energy. Congress rejected similar proposals last year.
Daniel Gabaldon, director and co-founder of Enovation Partners, a Chicago-based consulting firm that does the data analysis for Lazard’s levelized cost of storage report, expressed some skepticism that a $5 million investment could produce such a dramatic return in battery technology but said DOE’s investment would be “a really healthy development.”
Although Enovation doesn’t track the technologies cited by Walker for Lazard, Gabaldon said the prediction of an 80% reduction is in line with claims of early-stage companies pursuing alternatives to lithium-ion technology.
“We’ve seen very dramatic claims, and it would be certainly helpful for the suppliers, as well as potential buyers, to substantiate those claims,” he said in an interview. “Whether it comes to pass, who knows?”
