Focus on the hydrogen, security will be in Taipei?

Sixth, the execution, the date on which the notice was issued since the valid for five years. Involved in urban and rural planning, land management, and other matters in the notice required by laws and regulations and the relevant departments shall prevail.

with the development of hydrogen fuel cars, hydrogen and hydrogen fuel cell has been unprecedented attention. For the first time this year the two sessions, the hydrogen is written to the government work report, and puts forward & other Promote the construction of charging, hydrogenation facilities throughout the &; 。

new technology seems to provide the basis for the rapid development of hydrogen energy, recently, the scientists developed a new technology, made in sea water for hydrogen become no longer & other; Hard & throughout; , but also can prevent seawater for electrolytic equipment corrosion, etc. Hydrogen is how get? Really FuHanQing chemical byproducts in China? With hydrogen storage hydrogen, how to ensure the safe?

the hydrogen source of more extensive, mainly include hydrogen production from fossil fuels, hydrogen production, chemical by-product hydrogen containing hydrogen material recycling, solar and wind energy hydrogen production. Fossil energy hydrogen containing hydrogen production from coal gasification, natural gas reforming hydrogen and methanol cracking, hydrogen production, hydrogen containing hydrogen material containing water electrolysis hydrogen, ammonia decomposition hydrogen and sodium borohydride hydrolysis hydrogen production, chemical by-product hydrogen recycling containing caustic soda, coke and light oil cracking, etc.

　　“ There are various ways of hydrogen production, which technical route is more economic, need according to the specific analysis of regional resources endowment. ” Tsinghua wen-sheng gao the executive vice President of sichuan institute of energy Internet in daily reporter in an interview with science and technology, water electrolysis hydrogen production is the purified water injection in the dc electrolytic cell, water molecules on the electrode electrochemical reaction, broken down into hydrogen and oxygen, gas output, through regulating valve control is sent to storage tank. “ Water electrolysis hydrogen production in electricity, most of the costs if there is a cheaper off-peak, will greatly reduce the cost of hydrogen production. At present, hebei zhangjiakou have million kilowatt wind power demonstration bases, etc, due to abandon the wind power brownouts pressure, in guyuan county construction of our country's first comprehensive utilization of wind power hydrogen production demonstration project. But for shanxi datong coal reserves, coal chemical industry developed area, through the hydrogen production from coal gasification, can obtain a lower cost of hydrogen. ”

wen-sheng gao said, water electrolysis hydrogen production can get high purity hydrogen, will reduce the cost of the follow-up. With natural gas, methanol steam reforming of hydrocarbons and water gas conversion reaction, the resulting hydrogen usually contains 0. 5% - 2% of carbon monoxide. As a hydrogen fuel cell vehicles & other; Heart & throughout; , even if only 1 PPM ( One over one million) Carbon monoxide, fuel cell platinum electrode will & other; Toxic shock & throughout; , resulting in a decline in battery performance and shorten the life, therefore, & other; Using this technical route, the subsequent hydrogen purification costs are not low & throughout; 。

at the end of 2018, zhangjiakou explosion accident happened, killed 23 people, once rumours of explosion is associated with a local hydrogen production enterprises. Although later proved to be a rumor, but also caused the public attention to the safety of the hydrogen.

　　“ Any by using energy is high purity, energy intensive, there are some risks when using. Spontaneous, such as fuel cars and electric vehicles will also has appeared household gas leakage and explosion accidents. ” Wen-sheng gao said, in a sense, the hydrogen as a motor energy is safer than gas.

under atmospheric pressure, hydrogen is a kind of burning gas extremely easily, also known minimum density of the gas in the world, its density is only about 1/14 of the air. High energy density and natural gas, the main ingredient is alkane, which accounts for the vast majority of methane.

in fact, water electrolysis hydrogen production technology has a history of more than a century, our country is also worthy of the name of hydrogen production power, product quantity and type specifications are the top in the world. Hydrogen as a clean fuel, is already used to promote the rockets in the space program, etc.

wen-sheng gao said, industrial hydrogen production has a long time, the use of hydrogen is also very extensive. Industrial production, storage and use of hydrogen is a set of complete and effective rules and regulations.

such as the hydrogen use safety technical regulations in December 2008, the standard rules for gaseous hydrogen in use, replacement, storage, compression and charger ( Irrigation) Load and discharge process, and fire and emergency handling, safety aspects of the safety technical requirements.

　　“ Previously, the use of hydrogen relatively far away from the general public, the public on this & lsquo; New energy & rsquo; More strange, concern about the safety of is completely understandable. We can't put the industrial production, the use of hydrogen standard copied directly to the filling station construction, and should be studied in the process fully, on the basis of establishing barriers to entry, push related stipulation and implementation of policies and standards. ” Wen-sheng gao said.

in fact, the car without the gasoline hydrogenation this scene in wuhan, Beijing, jiangsu and other places has become a reality. Such as wuhan development zone ( Han district) Auto parts industrial park, plans to build reserves and hydrogenation of the largest amount of filling stations. At present, there are nearly 400 filling stations, all over the world, mainly concentrated in Japan and South Korea, Europe and North America.
