Siemens Energy receives certification for ‘H2-Ready’ power plant

Siemens Energy has received the certification for its “H2-Ready” power plant concept, the first manufacturer worldwide to receive the new certification from TÜV SÜD.

The globally operating provider of testing, inspection and certification services TÜV SÜD has developed the guideline for defining the “H2-Readiness” of power plants and is now offering an independent certification to original equipment manufacturers and EPC companies.

The certification of a combined cycle power plant includes three stages, according to Siemens Energy. First, a concept certificate for the conceptual design (including boundary conditions) during the bidding phase; second, a project certificate for the implementation phase, in other words, the final plant design and its specifications; and third, a transition certificate for the conversion of an existing CCPP to burn hydrogen – including a review of the retrofit measures and their impact on safety and performance.

“Our guideline enables OEMs, plant operators, and insurers to use a standard transparent framework”, says Reiner Block, CEO of the Industry Service Division at TÜV SÜD. “The certification covers a complete power plant with the relevant subsystems.” The “H2-Ready” certification, however, doesn’t certify existing power plants; rather, it provides a roadmap that describes how plants can be converted over time to co-fire hydrogen or even burn pure hydrogen.

As hydrogen increasingly plays a role in the decarbonization of energy systems, natural gas-fired combined cycle power plants (CCPP) are expected to run partially or fully on hydrogen fuel in the future.

This means that utilities that plan to purchase this type of power plant will expect a statement of the plant’s ability to use hydrogen as a fuel.

Some new combined or single cycle gas-fired power plants are already being advertised as “H2-Ready” today. Until now, however, there hasn’t been a clear definition of what this term means.

“Hydrogen is an important building block for decarbonising the energy supply. An independent certificate creates certainty for investments. We’re proud to be the first manufacturer to receive this important certification,” says Karim Amin, Executive Vice President Generation at Siemens Energy.

“If we design CCPPs today for future operation with hydrogen, they don’t just serve as a bridging technology to a CO2-free future, they’ll also make an important contribution to a reliable and affordable power supply in the long term.”
