Description

technical field [0001] The invention relates to the field of energy, and more specifically relates to an integrated energy storage and power generation system utilizing organic hydrogen storage materials. Background technique [0002] Due to the limited storage and non-renewability of fossil fuels, the whole world may face serious energy shortages in the near future. The development of new renewable energy is imminent. The energy density of hydrogen is as high as 120MJkg-1, and the calorific value of hydrogen is 142351kJ / kg, which is three times the calorific value of gasoline. Hydrogen is the most ubiquitous element found in nature and can be produced from renewable raw materials such as water, biomass or biogas. Hydrogen energy can be used in many forms. It can be used in internal combustion engines like gasoline to provide energy for power equipment through direct combustion, and it can also be used as an energy material in fuel cells. Hydrogen fuel cell technology has ...

Problems solved by technology

However, most of the electric energy used to electrolyze water to produce hydrogen today comes from fossil energy power generation, which is not only expensive, but also produces harmful gases that are harmful to the environment

[0003] Hydrogen is in a gaseous state at normal temperature and pressure, has the lowest density, and is flammable, explosive, and easy to diffuse. It is difficult to achieve safe storage and transportation of hydrogen under mild conditions. Therefore, the storage and transportation of hydrogen have always restricted the development of hydrogen energy. Bottleneck, each of these existing hydrogen storage technologies has certain deficiencies, and cannot fully meet the needs of the future hydrogen energy economy; the efficiency of high-pressure gaseous hydrogen storage is very low, and even when pressurized to 30MPa, the mass hydrogen storage density is still less than 3% , and there are unsafe factors such as container explosion and hydrogen leakage during transportation and use; low-temperature liquid hydrogen storage technology must be equipped with corresponding cooling devices, its mass hydrogen storage density is limited, and gaseous hydrogen is cooled to liquid Hydrogen consumes a lot of energy. In order to maintain a low temperature environment, the energy equivalent to 30% of the mass energy of liquid hydrogen will be consumed, resulting in a high cost of this hydrogen storage method; for metal hydride hydrogen storage, most metal hydrides are either Very stable, or very unstable, its lattice structure is easily destroyed after several hydrogenation cycles
