Power-to-Hydrogen-to-Power HYFLEXPOWER Demonstrator Completes Initial Tests Successfully 

Installation of SGT-400 gas turbine in France for HYFLEXPOWER project 

ENGIE Solutions, Siemens Energy, Centrax, Arttic, the German Aerospace Center (DLR) and four European universities, together forming the Hyflexpower consortium, have successfully completed the first stage of an innovative research project on renewable energy. Located at the Smurfit Kappa Saillat Paper Mill in Saillat-sur-Vienne in France, the program becomes the first industrial facility in the world to introduce an integrated hydrogen demonstrator. The first testing was completed in February, the next set of trials is set for summer of 2023. 

The aim of the HYFLEXPOWER project is to demonstrate that green hydrogen can serve as a flexible means of storing energy which can then be used to power an industrial turbine. The hydrogen is produced on site with an electrolyzer and used in a gas turbine with a mix of 30% hydrogen and 70% natural gas for power generation. 

The project marks the implementation of the world’s first industrial-scale power-to-X-to-power demonstration with an advanced turbine with high hydrogen content fuel. In 2023, trials will continue to increase the hydrogen ratio up to 100%. 

While the large-scale availability of green hydrogen is still some way off, the members of the consortium are focused on looking beyond 2030 and trialing new technology, such as hydrogen, today. This project will allow the partners to understand the technical feasibility of using hydrogen while retaining much of the existing energy infrastructure. This demonstrator would open great perspectives for industry. 

This innovative project involves collaboration across several industries, academic bodies, and research institutes. It was inspired by the European Commission’s “Hydrogen Strategy for a Climate-Neutral Europe” report, which outlines the essential role that hydrogen will play within the European Green Deal carbon neutrality and energy transition initiative. 

Stakeholders involved are ENGIE Solutions, Siemens Energy, Centrax, ARTTIC, German Aerospace Center (DLR), and Universities NTUA Athens of Greece, Lund of Sweden, Duisburg-Essen of Germany and UCL in the UK. Launched in 2020, the project involves significant funding by the European Commission, with two-thirds of the €15.2 million investment coming from the EU’s Horizon 2020 Framework Programme for Research and Innovation. 

Commenting on the end of the initial testing phase, Gaël Carayon, project director at ENGIE Solutions, said: “Ambitious projects like this one require taking partnerships to the next level and being united in a joint mission to make decarbonization a reality. Hydrogen will play a crucial role in the interaction between renewables and electricity storage and generation. ENGIE Solutions is proud to participate to this unique project.” 

Dr. Ertan Yilmaz, HYFLEXPOWER global director at Siemens Energy, said: “With the HYFLEXPOWER project we are showcasing that carbon-neutral and reliable power supply is possible – even for energy-intensive industries. Hydrogen-ready turbines will play a decisive role in climate-neutral energy, so it is very exciting to be looking forward to the next phase of testing.” For more info, see www.hyflexpower.eu
