Abstract:

As China’s economy has shifted from a stage of high-speed growth to a phase of high-quality growth,the construction of a green,low-carbon and clean energy system with renewable energy as the mainstay has become an important strategy for China’s energy development.Using the green electricity from offshore wind farms to power hydrogen production is not only a new way for offshore wind power consumption, but also an important means to replace traditional energy by new energy and to achieve carbon neutrality in the future.At present,the hydrogen storage and grid-connection costs of offshore wind-to- hydrogen systems are fairly high.Thus,how to achieve the optimal equipment configuration and control of a system in grid-connected state or off-grid state is an urgent problem to be solved.Based on the reviews on the current research progress made in offshore wind power generation,hydrogen production and storage and offshore wind power-to-hydrogen systems at home and abroad,the prospect for the technologies above are made.

Key words: carbon neutrality, offshore wind power, hydrogen production, hydrogen storage, wind-to-hydrogen system, renewable energy, coal-based battery
