Benefits of Using Electrolytic Hydrogen for Offshore Wind on China's Low-carbon Energy

To evaluate the benefits of offshore wind and electrolytic hydrogen on decarbonization in China, this paper presents an assessment of electrolytic hydrogen produced by offshore wind in China's coastal areas. The total coastal energy demand of load and hydrogen in 2050 is provided based on existing growth rates and future energy substitution trends. An optimization model with the goal of minimizing levelized cost of electricity (LCOE) and levelized cost of hydrogen (LOCH) is established to calculate the amount of hydrogen produced by offshore wind power. Finally, the carbon reduction is calculated by substituting hydrogen for traditional energy in the fields of power generation, heat, industry, and transport. The analysis underscores notable benefits of low-carbon system in China and may provide an essential reference for China's carbon neutrality.
