Key innovations
It can effectively reduce the DC power consumption of hydrogen production by more than 10%, and achieve a new breakthrough in China's alkaline electrolyzed water hydrogen production technology.
Potential economic benefits
Taking a green hydrogen project in northwest China as an example, photovoltaic power generation also purchases part of green electricity. The annual operating time of the hydrogen production system is about 4300 hours. Using Hi1 product, the LCOH of hydrogen production is reduced by 2.7%, which can save electricity bills every year. 6.4%, equivalent to a 25% reduction in initial investment.
Potential climate benefits
Electricity price and power consumption are the most sensitive variables that determine the energy efficiency of hydrogen production. LONGi Hydrogen Energy optimizes the cell structure, improves the uniformity of the cell flow channel, and takes into account material reliability and reaction efficiency to maintain a lower theoretical electrolysis voltage.
