Large-scale ocean mobile solar power generation system

Abstract

Provided is a solar power generation system capable of efficiently transporting energy generated at a distant location and converting the energy into electric energy. A solar power generation system (100) is configured to be provided with: a solar cell raft (5) which floats on the sea while being equipped with a solar cell unit (20) formed by connecting a plurality of solar cells (21) in the shape of a sheet on a floating body (23); a solar cell raft mother vessel (4) which is equipped with a seawater electrolysis device (57) for converting electric energy generated by the solar cell unit (20) into hydrogen and a liquid hydrogen tank (59) for storing the hydrogen obtained by the conversion, and can convey or tow the solar cell raft (5); a recovery vessel (6) which is equipped with a hydrogen recovery / storage means for recovering the hydrogen stored in the liquid hydrogen tank (59); a hydrogen recovery tank (9) which recovers the hydrogen from the recovery vessel (6) and stores the hydrogen; and a power plant (10) which converts the hydrogen stored in the hydrogen recovery tank (9) into electric energy.

Description

technical field [0001] The present invention relates to a solar power generation system, and more particularly, to a solar power generation system capable of efficiently delivering solar energy obtained from a raft of large-area solar cells floating at sea to convert the solar energy into electrical energy or to allow vehicles and the like to utilize the solar energy. Background technique [0002] Atmospheric carbon dioxide (CO 2 : The concentration of greenhouse gas) increases rapidly. As a result, phenomena such as frequent occurrence of abnormal weather and rising sea levels due to melting icebergs have occurred. Consequently, many scientists have predicted environmental changes if these phenomena are left unchecked, suggesting that something needs to be done globally. That is, many scientists insist that fossil fuels should not be used and that fossil fuel energy should be replaced with clean alternative energy. Furthermore, nuclear energy has been evaluated as an alt...

Problems solved by technology

However, while this trend is effective in sensitizing society about clean energy, it fails to have a sufficient impact on replacing currently used energy sources with clean energy.

Solar energy is clean energy, but the problem is that it needs a large area to accumulate energy due to low energy density, and it is difficult to obtain reliable output due to large time variations
