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

There are galore uncertainties astir pathways to mid-century c neutrality successful China and different large emitting nations, but 1 cardinal facet is certain: they volition necessitate monolithic expansions of upwind and star powerfulness to displace coal- and gas-fired power. The occupation is not the outgo and feasibility of capable renewable generation, but alternatively the challenges it introduces into the grid due to the fact that of its variability: the upwind doesn't ever stroke and the prima doesn't ever shine. 

Now, a squad of researchers from Harvard University, Huazhong University of Science and Technology and Tsinghua University person developed a cross-sector, high-resolution exemplary to find the champion and astir cost-effective mode for China's powerfulness strategy to go carbon neutral by 2050. A broad strategy moving beyond accepted readying assumptions to see ample offshore upwind generation, powerfulness storage, electric vehicles, greenish hydrogen production, and expanded transmission to equilibrium powerfulness connected a nationalist ground tin sharply trim costs of integrating renewable powerfulness into the grid. In fact, the results amusement that realizing the c neutrality of China's powerfulness strategy by 2050 is not lone feasible but request not needfully outgo much than reliance connected coal- and gas-fired power, with nary c constraints astatine all, to conscionable aboriginal energy demands. 

The probe was published successful Joule.
