TÜV SÜD declared Siemens “H2 Ready” under its new guidelines.
TÜV SÜD, a provider of testing, inspection and certification services has developed a guideline for defining the “H2-Readiness” of power plants and is offering an independent certification to original equipment manufacturers and engineering, procurement, and construction (EPC) companies. The guideline for obtaining certification was developed in collaboration with subject matter experts from Siemens Energy. Siemens is also among the first to receive the “H2 Ready” certification under the new guidelines.
Hydrogen can play a central role in the decarbonization of energy systems. In particular, natural gas-fired combined cycle power plants (CCPP) currently being built or planned are also 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.
“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.
The certification of a combined cycle power plant includes three stages: 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.
“Hydrogen is an important building-block for decarbonizing 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.”
The certification offered by TÜV SÜD can be applied to a wide range of solutions.
