Renewable energy sources could be used to drive alkaline electrolyzers for large-scale hydrogen production. Here Yanghong Xia and colleagues show that the fluctuating nature of renewable energy sources compromises the efficiency and consistency of electrolyzer performance. They also show that a strategy of multi-mode self-optimization can address this problem, extending the range of operation as well as improving efficiency at low loads.
