•ABB Ability™ OPTIMAX® will help hydrogen producers reduce their electricity costs by up to 20%

• Software will help improve the efficiency of hydrogen production in energy-intensive electrolytic cells

• The solution combines forecasting and day planning to ensure that businesses are competitive when dealing with the grid

ABB has released its ABB Ability™ OPTIMAX® energy management system for the green hydrogen industry, helping to reduce production costs by providing real-time visibility into energy consumption throughout the electrolytic water hydrogen production operation.

Electrolysis of water to produce green hydrogen is the process of separating water into hydrogen and oxygen using electricity produced from renewable energy sources. Green hydrogen is widely regarded as an important energy carrier for a low-carbon future. However, the production of green hydrogen by electrolytic water faces the severe challenge of high production cost and high energy consumption.

According to the Green Hydrogen Catapult, an initiative by a group of leading global energy companies, scaling up capacity to 50 times what is needed will require a 50 per cent reduction in the cost of green hydrogen production to below $2 per kg by 2026.

ABB OPTIMAX® energy management solutions support the entire life cycle of hydrogen plants, from simulation during the design and engineering phases to real-time visualization and monitoring of plant operations to help achieve cost reduction. ABB Ability™ OPTIMAX® measures two-way power flows and carbon dioxide emissions to provide reference data. Operators can use this data to determine the optimal level of energy consumption needed to support plant production and avoid waste.

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

“Scaling up green hydrogen production requires significant investment and high operating costs,” said Sleman Saliba, global product manager for Energy Management at ABB’s Process Automation Division. Nearly 70% of a hydrogen plant’s operating costs come from the electricity used to electrolyze water molecules during electrolysis. With OPTIMAX®, operators can run their industrial processes in a more energy efficient manner and reduce power costs by up to 20 percent with a technology investment of only 1 to 3 percent.”

Combined with intraday planning, OPTIMAX® allows operators to plan electricity consumption ahead of time, thereby increasing bargaining power with the grid and developing a recycling energy system based on forecasts of renewable energy supply and demand and current market price fluctuations.

ABB Ability™ OPTIMAX® energy management solutions 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.
