Hydrogen Production From Seawater in Context of Carbon Neutrality
Ocean is the source of life, how to efficiently develop and utilize seawater resources is the hope of sustainable development of human beings in the future. As the best energy choice in the low-carbon era, hydrogen plays an important role in the energy transformation from fossil to green energy. Electrolysis of water is a recognized method of green hydrogen production, but its energy and water consumption are very prominent. With the development of renewable energy, the loss of long-distance transmission of renewable electricity is also becoming more and more serious. To solve the above problems, the comprehensive production cost of green hydrogen can be reduced through renewable electricity coupled with seawater hydrogen production after desalination and seawater chemical resource utilization. Combined with the development of seawater resource utilization and renewable energy currently, the economic efficiency of this route is much higher than that of direct seawater electrolysis. This paper summarizes and analyzes two common ways of hydrogen production from seawater at present, discusses the feasible development methods and application technologies to achieve green hydrogen economy, which provides reasonable reference for the relevant research and industrial development of hydrogen production from seawater.
