Accelerate the development and deployment of energy storage technologies to drive the worldwide transition to renewable energy.
Renewables are projected to account for 95 percent of the increase in global power capacity by 2026 and could provide all global energy demand by 2050. Wind and solar energy, however, have an intermittency problem, requiring batteries to keep electricity flowing when the wind is not blowing and the sun is not shining. Energy storage technologies such as pumped-storage hydropower and lithium-ion batteries have been around for years but have limitations. To run the world on renewables will require 275,000 times more storage capacity than is available today. New technologies are being developed to achieve long-duration capacity, including batteries that store energy via trapped heat and devices that utilize the force of gravity. In addition to creating a regulatory environment in which these technologies can prosper, care must be taken to ensure storage technologies are cost-effective, use responsibly sourced materials, and seek consent from vulnerable communities.
