It is understood that at present, there are many aspects of hydrogen energy utilization in China, some of which have already achieved industrialization, and some are undergoing technological breakthroughs, mainly in the following areas:
The first is the oxyhydrogen cutting machine. This is the only hydrogen energy that has been industrially applied in the Chinese market. An oxyhydrogen cutting machine is a cutting and welding device that uses a hydrogen-oxygen gas mixture produced by water electrolysis as a fuel, and can be used as a substitute for cutting gas such as acetylene, propane, liquefied gas, and coke oven gas. Hydrogen oxygen cutting machines have now entered the continuous casting billet cutting process in steel plants, and pharmaceuticals, glass products, machinery industries, and shipbuilding industries are also used.
The second is the fuel cell. Hydrogen fuel cells are the main way to use hydrogen energy. The first hydrogen fuel cells were applied only to aerospace engineering. At present, more and more fuel cells are used in various fields such as transportation. The tail gas emissions of hydrogen fuel cell vehicles are water, with zero pollution to the air and the environment. At present, international big auto companies have begun to participate in the research and development of hydrogen fuel cells. The auto manufacturers that have successfully developed hydrogen fuel cell vehicles include General Motors, Mercedes-Benz and Toyota. Due to the current high cost of hydrogen fuel cells, it takes more than ten years to use it as a large-scale vehicle energy application.
The third is the hydrogen internal combustion engine. At present, many automobile manufacturing companies have produced hydrogen internal combustion engines. Experts predict that hydrogen engine cars will be used earlier than hydrogen fuel cell vehicles.
The fourth is nuclear fusion. It is still in the laboratory exploration stage.
The reporter also learned that China’s research and development of hydrogen energy can be traced back to the early 1960s, when Chinese scientists developed their own aerospace industry, developed liquid hydrogen as a rocket fuel, and developed and developed hydrogen fuel cells. Lots and effective work. The development of hydrogen as an energy carrier and a new energy system began in the 1970s. In 2009, China’s annual hydrogen production exceeded 10 million tons, ranking the first in the world; the production and sales of metal hydrogen storage materials surpassed Japan and became the world’s largest.
Interviews in the industry recently revealed that China’s annual hydrogen production has exceeded 10 million tons, ranking the first in the world; the production and sales of metal hydrogen storage materials have surpassed Japan and become the world’s largest. At the same time, China's hydrogen energy applications have been in the field of industrialization.
