kylin-tech's products were exhibited in Singapore, Malaysia and other countries, and received the attention of local government departments and various companies, and business negotiations and consultations were held. Under the dual-carbon goal, according to the forecast of the hydrogen supply structure in the industry from 2020 to 2050, the proportion of traditional hydrogen production methods will gradually decrease, while the proportion of renewable energy hydrogen production will gradually increase. Using cheap green electricity with water electrolysis hydrogen generator not only greatly reduces the cost of hydrogen production, but also consumes abandoned wind and solar power. Hydrogen production from water electrolysis has a high efficiency of converting electricity into hydrogen, and is a process without carbon emissions. Vigorously developing hydrogen production from renewable energy will help to achieve a low-carbon environment.
