The globally operating provider of testing, inspection and certification services TÜV SÜD 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 certification increases investment security for utilities. Siemens Energy is the first company worldwide to receive this certification for its “H2-Ready” power plant concept. The guideline for obtaining certification was developed in collaboration with subject matter experts from Siemens Energy.
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. That’s why 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.
