Research on Comprehensive Energy Management Platform for Hydrogen Production from Renewable Energy

  Introduction  Hydrogen energy is a kind of green and efficient energy, which can be converted into electric energy and thermal energy by many ways. Hydrogen production from renewable energy is an important support to achieve the goal of "carbon peak and neutrality." Hydrogen production from renewable energy is a new kind of project, which is the combination of electric power industry and chemical industry. The coupling between systems is not strong. Improving the comprehensive utilization of energy is the research focus of hydrogen production from renewable energy.   Method  The main hydrogen production processes at present were introduced, the main characteristics of gray hydrogen, blue hydrogen and green hydrogen were compared, the main systems of hydrogen production from wind and photovoltaic power were described. Then it was proposed to build a comprehensive energy management platform to manage and control all systems of hydrogen production from renewable energy as a whole.   Result  The control strategy formulated on the comprehensive energy management platform can balance the power, optimize the scheduling, reduce the waste of wind and photovoltaic power, and reduce the unit hydrogen production cost.   Conclusion  The comprehensive energy management platform can improve the comprehensive utilization of hydrogen production from renewable energy, play a supporting role in the promotion of hydrogen production from renewable energy projects, and have important reference significance for researchers in this area.
