The World Bank aims to break through that bottleneck,
announcing plans Wednesday to invest $1 billion—and leverage it by another $4 billion—to boost developing countries' energy storage capacity from 4.5 to 17.5 Gigawatt hours by 2025.
While solar energy is abundant, the sun goes down around 5:00 or 6:00 pm in most of the African continent, making storage capacity crucial to providing a continuous supply of electricity.
It is a limitation with no impact on diesel and other fossil fuels in wide use to generate electricity.
Africa, where solar power is an "unmissable" source of energy, will be the first to benefit, said Riccardo Puliti, head of energy practice at the World Bank.
Bangladesh and other developing countries of Southeast Asia also will benefit from the World Bank's investment, which aims to stimulate a fledgling market and to create a "virtuous circle."
"We want to develop the market for batteries in developing countries," Puliti told AFP. "Storage has a great future."
Lithium batteries are available today, but they are made principally for electric vehicles.
