Fun facts about the 2022 Winter Olympics

Ø China's Olympic torches are all hydrogen-fueled

Ø The main torch of the Beijing Winter Olympics was lit with hydrogen fuel at the opening ceremony

Ø 625 hydrogen fuel cell vehicles were put into the competition area

At the same time, China's first hydrogen testing laboratory was officially put into operation in Chongli, Hebei Province, China is using its technological strength to interpret the concept of "Green Olympics".

 

The hydrogen industry is booming

Hydrogen energy is the cleanest of all known energy sources, and hydrogen vehicles are considered to be the "ultimate new energy vehicle solution". Many countries’ governments have introduced supportive policies in the hydrogen fuel cell vehicle industry. It is predicted that the global market size of fuel cell vehicles will exceed 1.98 million units in 2030.

As the core of hydrogen energy vehicles, hydrogen energy fuel cells will also see explosive growth and the market demand will increase greatly. However, due to the precise structure of fuel cell, it needs higher technical support in the production process.

 

Laser application in hydrogen fuel cell

HGTECH has developed hydrogen fuel bipolar plate welding, cutting, coding and automation solutions for the bipolar plate, the "skeleton" of fuel cells, and has been closely laying out cooperation with the hydrogen fuel bipolar plate processing market, led by bipolar plate welding equipment.
