Abstract

The invention discloses an integrated system for production, storage, transportation and utilization of hydrogen energy on the basis of solar energy and biomass gasification. The integrated system comprises four parts namely a hydrogen production sub-system, a hydrogen storage sub-system, a hydrogen transportation sub-system and a hydrogen utilization sub-system, wherein the hydrogen production sub-system comprises a heliostat, a gasification reactor, a pre-heater and a cooling purifier; the hydrogen storage sub-system comprises a new gas compressor, a gas-steam combined cycle device, a methanol heat exchanger, a methanol synthetic tower, a gas-liquid separator, a rectifying tower and a methanol tank; the hydrogen transportation sub-system comprises a transportation device, wherein the methanol tank is connected with a methanol storage station by virtue of the transportation device; the hydrogen utilization sub-system comprises the methanol storage station, a trough type solar absorber / reactor, a hydrogen pressure swing adsorption purification device, a city gas pipe network system, a hydrogen station and a fuel cell. By adopting the integrated system disclosed by the invention, hydrogen can be prepared by making full use of renewable energy sources; the efficient storage and long-distance transportation of hydrogen energy can be realized by virtue of a high-quality carrier namely methanol; moreover, the problems of unbalanced resource distribution and economic development at present are solved.

Description

technical field [0001] The invention relates to the technical field of efficient utilization of hydrogen energy, in particular to an integrated system for hydrogen energy production, storage and transportation based on solar energy and biomass gasification. Background technique [0002] Energy is one of the key elements for human survival and development, and also an important material basis for national economic and social development. However, the existing energy supply system mainly relies on fossil fuels such as coal and oil. Excessive use of fossil fuels has caused serious pollution to the environment and exacerbated global warming. As far as China is concerned, the coal-dominated energy structure has severely restricted the current rapid economic and social development, and at the same time, the excessive dependence on foreign oil has seriously threatened national energy security. At the same time, the contradiction between the non-renewability of fossil fuels and the...
