Analysis of scenarios and technologies for offshore wind power ammonia production in deep-sea
Offshore wind power will develop towards deep-sea,large-scale and floating,while the energy storage and consumption of offshore wind power are challenges.Based on the interpretation of domestic and foreign literature in this field,it is found that offshore wind power ammonia production in deep-sea has the advantages of realizing large-scale energy storage and energy transfer from the sea to the land consumption end,and facilitating large-scale consumption and utilization in the downstream.Combined with the experience of technology and equipment in China's offshore oil and gas industry,three innovative application scenarios for offshore wind power ammonia production in deep-sea:deep water semi-submersible ammonia production and storage platform,floating ammonia production,storage and unloading ship and floating offshore wind power platform were put forward,and the technical routes for ammonia production in different scenarios were summarized.It is concluded that large and medium-sized low-temperature and low-pressure ammonia synthesis technology is suitable for semi-submersible ammonia production and storage platform and floating ammonia production,storage and unloading ship,while small skid-mounted low-temperature and low-pressure ammonia synthesis technology and new electro-catalytic ammonia synthesis technology are more suitable for floating offshore wind power platform.The development status and difficulties of ammonia production technologies were analyzed.Finally,some suggestions on the future research direction of offshore wind power ammonia production in deep-sea were given.
