India’s renewables revolution needs what other countries are fast adopting: water battery

Progress in energy storage will soon mean energy security for India, as the country races ahead with large renewable power commitments. Already fifth in the world in renewables, India now says it will exceed its 2022 target of 175 gigawatts of installed renewable capacity. Speaking at the United Nations Climate Action Summit in September, Prime Minister Narendra Modi committed his nation to more than doubling that target, to 450 gigawatts.

Yet, regardless of total capacity, we know discontinuous power is inadequate power. Wind and solar technology can generate electricity only when the wind blows or the sun shines, and green power that floods the grid and then recedes puts immense pressure on transmission systems and end users alike. Balancing this fluctuating supply is the lynchpin of a clean energy future, and the key to achieving that balance is reliable and efficient energy storage.

India hasn’t moved as swiftly on storage as it has on generation, however, leaving its lofty green commitments incomplete. The government has conducted only sporadic lithium-ion storage tenders and pilot projects, and there have been only small-scale storage experiments in the private sector. Read More
