A new report from the International Renewable Energy Agency (IRENA) predicts that global battery storage capacity for electricity could rise from 1GW at present to 250GW by 2030.

The forecast came in the third edition of the agency’s “REthinking Energy” report.

Demand for battery storage is increasing rapidly and playing a larger part in integrating variable renewables into the wider electricity grid, the paper said.

Global investment in renewables has steadily grown for more than a decade, IRENA said, rising from less than $50 billion (£41bn at today’s prices) in 2004 to a record $305bn in 2015.

Off-grid renewables

IRENA Director-General Adnan Amin said: “Achieving universal electricity access by 2030, will require us to boost global power generation – nearly 60% of that will have to come from stand-alone and mini-grid solutions.

“Meeting this aim with off-grid renewables depends on the right combination of policies, financing, technology and institutional capacity.

“Making needed changes and accelerating deployment will allow countries to address global issues in sustainability, education, gender equality, health, water and food.”
