    The third preparatory（预备的） meeting for the Shenzhen First Session International Hydrogen and Fuel Cell（燃料电池） Leaders Summit was held on November 28 in Shenzhen, Guangdong Province. Nearly 100 experts attended it. The theme of the meeting was “Energy revolution（革命）, hydrogen (氢) changes the world”.

The meeting focused on the use and safety of hydrogen. In the meeting, experts discussed the direction of developing the hydrogen industry in China, the basic research of hydrogen, the development of hydrogen fuel cell technology, the new way to develop hydrogen and fuel cells in Shenzhen and so on.

Hydrogen is secondly energy. And it’s produced by primary energy (一次能源). For example, if we use some energy to produce electricity, then we can use the electricity to produce hydrogen. Hydrogen fuel cells have a few advantages. Firstly, they take only a few minutes to recharge(充电）. Secondly, they aren’t affected by temperature. Thirdly, hydrogen is very safe, safer than gasoline. At present, because of climate change, the world is developing this energy. It doesn’t contain carbon. Many countries have made a plan for hydrogen. Japan, Germany and the US are the leading ones. China has used different policies to encourage the development of hydrogen since 2016. It will become a kind of very important energy like electricity in the future.

Yu Yiping, chairman of the board of directors at Scientific Valley Group, said, “In order to prepare the summit, we’ve done lots of work. We went to other countries, such as Germany, France and the US, to learn experience. We also went to California, the US to learn about the hydrogen production, storage and transportation, and the construction of hydrogen refueling(补给燃料） stations.” Du Zheng, vice director of the Nanshan District Science, Technology and Innovation Bureau, said, “We are pushing forward the development of hydrogen in three ways: the planning of the hydrogen industry, the policy guidance and the building of some basic facilities, such as hydrogen refueling stations.”
