High-economy CO2 offshore platform

Abstract

A high-economy CO2 offshore platform is characterized in that a water electrolysis hydrogen production module, a hydrogen storage tank, a methanol synthesis module, an injection module for CO2 storage, a CO2 liquefaction module and a CO2 pretreatment module are arranged above a floating platform deck, horizontal shaft or vertical shaft fans are fixed at the two ends of the bow of the platform, a solar layer is laid above the platform, and the horizontal shaft or vertical shaft fans are fixed at the two ends of the bow of the platform. The solar layer is formed by continuously laying a plurality of solar photovoltaic panels, and a CO2 storage bin and a methanol storage bin are arranged in the platform body. The horizontal shaft fan and the solar energy layer provide generated electricity for the hydrogen production module for hydrogen production, the hydrogen production module conveys produced hydrogen to the hydrogen storage tank or the methanol synthesis module, and the hydrogen production module can also utilize hydrogen to reversely generate electricity. The floating type platform is adopted, the device is suitable for offshore and deep sea areas, the operation range is wide, offshore wind power generation is adopted for supplying power to CO2 offshore storage operation, the requirement for conventional fuel in the CO2 offshore storage process is reduced, the energy consumption cost of CO2 offshore storage is reduced, and very high economical efficiency is achieved.
