The ALK Hi1 series products have passed empirical testing and its performance has been certified by third-party authorities such as Det Norske Veritas and DERKA Testing and Certification (Shanghai) and measured in accordance with national standard.

The full-load DC power consumption of ALK Hi1 can be as low as 4.3kwh/Nm3 and is lowered for ALK Hi1 Plus down to 4.1kwh/Nm3 in order to adapt to hydrogen production scenarios demanding higher utilisation hours.The company aims to reduce the electricity consumption of hydrogen production units and lower the levelized cost of hydrogen (LCOH).

Electricity price and energy consumption per unit of hydrogen production are the two variables that contribute to the highest sensitivity of LCOH.

LONGI series products are rated to have level one energy efficiency of hydrogen production system.

The company claims that full-load DC power consumption of the global electrolysed water hydrogen production industry, including alkaline water hydrogen production technology (ALK) and proton exchange membrane electrolysis water (PEM) power, is in the range of 4.5 to 4.6kmh/Nm3.

The products have the characteristics of high efficiency and high production capacity, which means reduction of DC power consumption by more than 10%, and the LCOH of hydrogen production in different scenarios will be greatly cut down.

Last year, LONGI announced it has won the Sinopec Green Hydrogen Demonstration Project, to supply ‘world leading large scale’ alkaline water electrolyser equipment.

The China-based company will provide its water electrolysis equipment with a four to one electrolyser, gas-liquid separation system, which LONGI claims can achieve 4000Nm3/h of hydrogen production.
