Wind, solar and storage are on the cusp of collaborating to provide near carbon-free energy at cost equal to the cheapest fossil fuels, according to MIT chemist and former CIA director John Deutch.
Deutch proposes setting up a competition between energy developers, allowing them to bid on a 20-year contract to provide a system that meets 95 percent of demand in an area using solar, wind and storage alone. All the government has to do is create a “regulatory envelope” within which the project will be allowed. And then be sure to publicize the results
Deutch and his collaborators, including Yet-Ming Chiang of MIT’s Department of Material Science and Engineering, demonstrated their proposal by calculating the costs of such a system in central Texas. The hypothetical electricity cost 13 cents per kilowatt hour to produce today with lithium-ion batteries, but only 6 cents with the flow batteries likely to replace lithium ion for grid storage. That’s the cost of the cheapest energy produced by natural gas, he said.
