An estimated 150 GW of battery storage and 325 GW of pumped-storage hydroelectricity will be needed to avoid the worst effects of climate change and accelerate sustainable energy transformation and economic growth, according to a new report.

Renewables and Electricity Storage, part of part of the International Renewable Energy Agency’s REmap 2030 programme, prioritizes 14 action items across five priority areas where governments and industry can work together to facilitate the development of policies on electricity storage for renewables.

IRENA's REmap 2030 report finds the share of renewables in the electricity sector must double to 45% by 2030 to mitigate the risk of climate change.

“Now is the time to think about integrating large-scale battery storage into the global energy system,” said IRENA Director-General Adnan-Z Amin. “This roadmap is a starting point for all policy makers seeking to integrate greater storage capabilities, which is necessary to ensure the world is ready for the next phase of growth for renewable power systems.”

The five priority areas identified include electricity storage to support renewables in islands and remote areas, consumer-located storage for self-consumption in countries with high shares of rooftop solar PV systems, generator and grid-located storage for countries with grid infrastructure constraints and system analysis tools for countries preparing to transition their power sector towards renewables.

The roadmap is the product of four stakeholder workshops involving more than 200 electricity storage experts from 50 countries.

“The value of this roadmap is that it brought together policy makers from across the globe with the leading industry experts and academics,” said Janice Lin, chairperson of the Global Energy Storage Alliance.

“At every workshop, we were asked to prioritise and refine our assessments. The roadmap is truly a product of international cooperation."
