According to the hydrogen energy power generation system, the air cylinder with the upper piston and the lower piston is installed, hydrogen and nitrogen are used as working media, the hydrogen absorption and desorption effects of the metal hydrogen storage material are utilized, the expansion machine is driven to work for power generation, the energy of the nature is fully utilized, energy conservation and emission reduction are facilitated, and economic benefits are created.

Description

technical field [0001] The invention belongs to the technical field of energy comprehensive utilization, and relates to a hydrogen energy power generation system utilizing metal hydrogen storage materials. Background technique [0002] The natural world is full of unlimited energy at normal temperature, such as air and sea water, which have potential for development. Most of the energy on the earth comes from the sun. In today's increasingly scarce energy sources, new renewable, green and clean power generation technologies are increasingly valued. Among new energy sources, hydropower and wind power generation technologies are widely used and the technologies are relatively mature. The development potential of hydropower is not great, and the wind power is too scattered, so it can only be used in some specific areas, and the investment of hydropower and wind power generation devices is very large, covering a large area. Air energy has gradually entered people's field of vi...

Problems solved by technology

This utility model patent can convert air energy into kinetic energy to drive the generator set to rotate. However, due to the energy consumption of the cooler condensation, the energy conversion rate of the system becomes lower, and the generator generates less power, so the actual promotion value is limited.
