ABB launches energy management system for green hydrogen

ABB has introduced its energy management system ABB Ability™ OPTIMAX® to the green hydrogen market to help reduce costs of production by enabling real-time visibility of energy consumption across operations.
Green hydrogen made via electrolysis – a process of using electricity from renewable sources to split water into hydrogen and oxygen – is widely considered an important energy vector for achieving a low carbon future.
It does pose significant challenges in the way of high production costs and energy intensive processes.
According to the Green Hydrogen Catapult, a global initiative made up of leading energy companies, to scale up production capacity to the 50 times needed, the cost to produce green hydrogen needs to drop by 50% to less than $2/kg (€1.92) by 2026.
ABB’s OPTIMAX® supports this by serving every aspect of a hydrogen plant lifecycle, from simulation at design and engineering phases to real-time visualization and monitoring when in operation.
The software measures bi-directional power flows and carbon dioxide emissions providing contextual data which operators can use to determine optimal energy consumption levels required to support plant processes and minimize waste.
“Scaling up green hydrogen production requires significant capital investment as well as high operating costs,” said Sleman Saliba, global product manager energy management for ABB Process Automation.
“Nearly 70% of the total operating costs to run a hydrogen plant comes from the electricity needed to split the water molecule in the electrolysis process. With OPTIMAX®, for between 1-3% technology investment, operators can run their industrial processes in the most energy efficient way and gain up to 20% reduction in electricity-based costs.”
Incorporating intra-day planning, operators can also utilise OPTIMAX® to plan ahead to trade competitively with the grid, developing a circular energy system that is based on forecasts of renewable energy availability against demand, also considering market electricity prices.
