4.0kwh/Nm3! LONGi Hydrogen ALK Hi1 Has Been launched! ——Start the Era 1.0 of Hydrogen Production Energy Efficiency

On February 14, 2023, LONGi Hydrogen, a wholly-owned subsidiary of China’s solar giant LONGi Green Energy Technology Co., Ltd. (LONGi), officially launched a new generation of alkaline electrolyzed water hydrogen production equipment ALK Hi1 to the world in Beijing, continuously exploring the lowest of energy consumption and redefining the height of energy efficiency.

From Photovoltaic LCOE to Hydrogen LCOH

“The history of the development of human civilization is also the history of energy development”. In the context of “Carbon Peaking and Carbon Neutrality”, the trend of energy development will gradually shift from carbon-based energy to silicon-based energy, and then to hydrogen energy. Li Zhenguo, President of LONGi, said that solar power has become the world’s most economical clean energy, and “photovoltaic hydrogen production” is a real “duel-clean” energy solution.

Economy is the main factor hindering the development of green hydrogen. Based on the rich experience in the photovoltaic field, LONGi found that, similar to LCOE of PV, the core path is to reduce the electricity consumption of hydrogen production units, that is, for the same electricity consumption to produce more hydrogen. The lower the Levelized Cost of Hydrogen (LCOH) is, the more cost-efficient green hydrogen will be.

Minimum 4.0 kWh/Nm³! Continuously Lowering Energy Costs

Electricity price and energy consumption per unit of hydrogen production are the two variables that contribute to the highest sensitivity of LCOH. The full-load DC power consumption of ALK Hi1 can be as low as 4.3kwh/Nm³. It is even lower for ALK Hi1 Plus, down to 4.1kwh/Nm³, in order to adapt to hydrogen production scenarios demanding higher utilization hours. It even hits 4.0kwh/Nm³ when the ampere density is 2500A/㎡.

Research also shows that full-load DC power consumption of the global electrolyzed water hydrogen production industry,…
