Recently, ABB launched ABB Capability for the green hydrogen industry ™ OPTIMAX ® The energy management system helps to obtain real-time visibility of energy consumption in the whole operation process of electrolytic water hydrogen production, thus helping to reduce production costs.

Electrolysis of water to produce green hydrogen is the process of separating water into hydrogen and oxygen using electricity produced by renewable energy. Green hydrogen is widely considered as an important energy carrier to achieve a low-carbon future. However, the production of green hydrogen from electrolytic water is facing serious challenges such as high production cost and high energy consumption.

According to the initiative “Green Hydrogen Catapult” (meaning “green hydrogen promotion plan”) jointly launched by several leading energy companies in the world, to expand the production capacity to 50 times the required capacity, by 2026, the production cost of green hydrogen needs to be reduced by 50% to less than $2 per kilogram.

From simulation in design and engineering stage to real-time visualization and monitoring of plant operation, ABB OPTIMAX ® The energy management solution provides support throughout the whole life cycle of the hydrogen plant to help achieve the goal of cost reduction. ABB Ability ™ OPTIMAX ® It can measure two-way power flow and carbon dioxide emissions and provide reference data. Operators can use these data to determine the optimal energy consumption level required to support plant production and avoid waste.

ABB Ability ™ OPTIMAX ® The data provided can also be used to improve the hydrogen production efficiency and safety of the electrolytic cell module, adjust the speed of each module and ensure that it is only used when needed.

Sleman Saliba, global product manager of energy management of ABB Process Automation Division, said: “Expanding the scale of green hydrogen production requires a lot of investment and high operating costs. Nearly 70% of the operating costs of hydrogen plants come from the electricity consumed by electrolysis of water molecules in the electrolysis process. With the help of OPTIMAX ®， Operators can operate their industrial processes in a more energy-efficient way with only 1-3% technology investment, and reduce the power cost by up to 20%. “

In combination with intra-day planning, operators can use OPTIMAX ® To plan the electricity consumption in advance, so as to improve the bargaining power of the transaction with the power grid, and develop a circular energy system based on the prediction of the supply and demand relationship of renewable energy and the fluctuation of the current market electricity price.

ABB Ability ™ OPTIMAX ® The energy management solution can also be used to optimize the integration and integration of green hydrogen with existing hydrogen networks and infrastructure that is expected to be developed in the future.
