TÜD-SÜD has certified the hydrogen-readiness of John Cockerill’s heat recovery steam generators (HRSGs).
The Belgian firm’s HRSGs are steam generators that recover heat from hot flue gases at the outlet of gas turbines. It has modified the heat recovery boiler design to allow the generators to operate with up to 100% hydrogen instead of fossil fuels.
The system has now been certified for combined cycles and cogeneration applications, with drum-type and once-through boiler designs. The certificate also validates the company’s expertise in vertical and horizontal HRSG designs, with or without supplementary or fresh air firing, for new installations or retrofits.
TÜD-SÜD has confirmed that John Cockerill’s hydrogen-ready concept for the bidding phase of new projects meets its requirements.
“We are proud to receive this prestigious certification,” said Eric Absil, President of John Cockerill’s Energy Solutions Business Line, “[it] makes John Cockerill one of only two manufacturers to receive this recognition.”
Absil continued, “Designing heat recovery steam generators for future hydrogen operations will significantly contribute to a reliable and sustainable power supply in the long term and will propel us in the energy transition, and the zero-emission generation.”
The news comes not long after the UK Government committed to deliver a support mechanism for hydrogen’s use in power generation and an associated business model to spur private investment.

Hydrogen gas turbines: Flexible and reliable clean power
First patented in 1899, gas turbines have become a cornerstone of global energy systems. Today, they account for approximately 20% of the world’s electricity generation. Known for their flexibility, fast ramp-up times and high efficiency, gas turbines have emerged as a key solution for countries transitioning away from coal.
A gas turbine is an internal combustion engine (ICE) that operates with rotary motion. Widely powered by natural gas, the systems are comprised of three core components: compressor, combustor and turbine.
Despite being a cleaner alternative to coal power, with natural gas emitting 50-60% less carbon dioxide (CO2), natural gas turbines produce vast amounts of CO2, NOx and other pollutants.
As demands on grid capacity continue to rise, proponents of the technology believe gas turbines will still have a key role to play in a decarbonised energy system, but powered by clean fuels, such as hydrogen.
