Siemens energy has become the first enterprise in the world to obtain this certification with its “hydrogen energy application ready” power plant project scheme. This certification is provided by t Ü v s Ü D (“t Ü V Nande”), a testing, inspection and certification service provider operating worldwide. T Ü V Nande has developed a “hydrogen technology application readiness index” for power plants and provided independent certification to original equipment manufacturers and engineering, procurement and construction (EPC) companies to improve the investment safety of utilities. The qualification criteria for certification are formulated by siemens energy experts in this field in cooperation with t Ü v South Germany.

Hydrogen energy can play a central role in the decarbonization process of energy system. In particular, the natural gas combined cycle power plant (CCPP) currently under construction or planned to be constructed is also expected to use hydrogen as fuel in part or all in the future. This means that utilities planning to purchase this type of power plant in the future will be interested in obtaining a certificate that the power plant can use hydrogen as fuel.

Although some new combined cycle or single cycle gas-fired power plants have taken “hydrogen energy technology application readiness” as the publicity point, so far, the industry has not given a clear definition of “hydrogen energy technology application readiness”.

Reiner block, CEO of industrial services of t Ü v South Germany group, said: “our qualification standards enable OEMs, plant operators and insurance companies to use a standard and transparent framework. This certification covers all relevant subsystems of power plants.” however, “hydrogen technology application is ready” Certification does not certify existing power plants; Instead, it provides a roadmap showing how power plants can convert to hydrogen over time, even using hydrogen only as fuel.

This is why the certification of combined cycle power plant includes three stages: first, the concept certificate of conceptual design (including boundary conditions) in the bidding stage; Secondly, the project certificate in the implementation stage, or the final power plant design and specification; Finally, the transition certificate for the conversion of existing combined cycle power plants to hydrogen burning – including the review of transformation measures and their impact on safety and performance.

Karim Amin, global executive vice president of siemens energy, said: “Hydrogen is an important cornerstone for decarbonization of energy supply. Independent certification enhances the certainty of investment. We are honored to be the first manufacturer to obtain this important certification. If we design combined cycle power plants based on the standard that hydrogen can be used in the future, these power plants will not only serve as bridge technologies to a carbon free future, but also make an important contribution to reliable and affordable power supply in the long run. “

In order to achieve the climate ambition, it is not enough to transform the combined cycle power plant into a hydrogen burning power plant. The certification provided by t Ü V Nande is applicable to a wide range of solutions. Siemens energy has provided comprehensive solutions with hydrogen power generation, storage and re electrification. At present, XIMENZI energy is participating in the construction of several power plants designed to burn some or all hydrogen.
