PTX技术在可再生能源大规模储能和消纳中的应用分析OACSTPCD

The goal of carbon peaking and carbon neutrality has promoted the development of renewable energy in China,and the high proportion of unstable power is facing challenges in achieving large-scale energy storage and cross-regional consumption.Hydrogen energy storage,in its broader sense,involves using renewable energy to electrolyze water to produce hydrogen,which is along with hydrogen-based chemicals,serves as a medium for energy storage and consumption.Green electricity synthesis(Power-to-X,PTX),combined with CO2 chemical conversion technology,harnesses the rapid growth of the hydrogen industry to produce zero-carbon products such as methane,methanoll and ammonia.These products can enter existing energy infrastructure systems,enabling high density,low-cost energy storage,transportation,and distribution,quickly addressing consumption without altering end-use habits.Explanations and analyses of green methane,green methanol and green ammonia production using green electric power were provided,and it is proposed that PTX can promote the integration of renewable energy with existing industries,thus achieving efficient utilization and consumption of renewable energy with broad prospects.
