Green electricity is mature, but the low-carbon transformation of heavy industry and transportation cannot rely solely on green electricity, but also requires hydrogen energy. The European Parliament passed a new law on the 11th, confirming that the EU natural gas market and infrastructure will gradually transform to hydrogen, and build a hydrogen energy market and hydrogen transmission network (hydrogen network) for the low-carbon transformation of industry. The bill still needs to be voted on by the EU Council before it can be formally implemented. The European Union determines the direction of hydrogen energy for the low-carbon transformation of industry. The European Parliament passed the hydrogen and decarbonised gas markets package on the 11th to encourage investment in hydrogen energy and accelerate the transition to biomethane and low-carbon energy. Sustainable energy sources such as hydrocarbons. "Euractiv" reported that European Parliament member Jens Geier said that this is "the legal basis for the development of the European hydrogen market and the beginning of the phase-out of natural gas." Another congressman, Jerzy Buzek, said that the future energy market will have two major sources - green electricity and green gas. The EU's goal is to reduce net greenhouse gas emissions by at least 55% by the end of 2030 compared to 1990 levels. According to "Hydrogen Insight", the European Union has defined "low-carbon hydrogen" and its derivatives (such as synthetic methane). The production process of this type of hydrogen will emit 70% less greenhouse gases than natural gas. The European Commission proposed a hydrogen energy draft in 2021. Gale pointed out that Europe’s steel and chemical industries need to decarbonize and
