Rethinking grid integration of a massive renewable power expansion to achieve carbon neutrality

There are many uncertainties about pathways to mid-century carbon neutrality in China and other major emitting nations, but one fundamental aspect is certain: they will require massive expansions of wind and solar power to displace coal- and gas-fired power. The problem is not the cost and feasibility of sufficient renewable generation, but rather the challenges it introduces into the grid because of its variability: the wind doesn’t always blow and the sun doesn’t always shine.
