Hydrogen | Lhyfe in Lubmin


Lhyfe plans to produce up to 330 tons of green hydrogen per day at an 800 MW electrolysis plant to be located in Lubmin, eastern Germany, with commissioning targeted for 2029. Part of Lhyfe’s backbone development strategy, the plan is for the plant to feed into the proposed German core hydrogen pipeline network, for which the German government recently unveiled a €20 billion financing plan. Over the last two years, Lhyfe has developed a backbone project portfolio amounting to about 3.8 GW of electrolysis (as of June 2023), some 37% of its total project pipeline, including large projects such in Perl (Saarland) and Delfzijl (the Netherlands) located near future hydrogen transport infrastructure.


The Lubmin site is located very close to the anticipated German hydrogen backbone and offers good access to offshore wind farms and to the German grid. The new electrolysis facility will be built on the site of the decommissioned Greifswald VVER nuclear power plant. “This location is of strategic importance to us,” emphasises Luc Graré, Head of Central & Eastern Europe at Lhyfe. “Lubmin meets all the requirements to establish itself as a sustainable centre for green hydrogen in the long term.” The project’s implementation is subject to the granting of operating authorisations, construction permits, as well as to financial investment decisions, Lhyfe points out.


ACWA breaks ground in Uzbekistan


ACWA Power reports that it has broken ground on a 3000 t/y green ammonia project in Uzbekistan, following the signing of hydrogen purchase and power purchase agreements in May 2023. This is the first phase of a project that will eventually see 2.4 GW of wind energy powering the production of 500 000 tonnes of green ammonia per year. When fully completed, this is expected to be ACWA Power’s second operational utility-scale green hydrogen project after the NEOM Green Hydrogen Project in Saudi Arabia, which is a joint venture between ACWA Power, NEOM and Air Products.


HYFLEXPOWER world first: gas turbine operation on 100% green H2


Installed on the site of paper-based packaging manufacturer Smurfit Kappa at Saillat-sur- Vienne, France, the HYFLEXPOWER project consists of producing, storing and “re- electrification” of 100% renewable hydrogen. The hydrogen is produced by a 1 MW electrolyser on-site, stored, and used to fire a Siemens Energy SGT-400 industrial gas turbine. In 2022, an initial series of tests enabled the industrial gas turbine to operate with a 30% H2

natural gas blend. The power-to-hydrogen-to- power demonstrator has now shown that state-of- the-art turbines with dry low emissions technology can be fuelled with up to 100% H2 any blend of natural gas and H2


as well as with .


The HYFLEXPOWER consortium includes Siemens Energy, ENGIE Solutions, Centrax, Arttic, DLR (German Aerospace Center), and four European universities.


The project has received substantial funding from the European Union’s Horizon 2020 innovation and research programme.

Consortium lead, Siemens Energy, supplied the electrolyser for the project and developed


the hydrogen ready gas turbine. ENGIE built the hydrogen production, storage and supply facilities for the demonstrator. Centrax was responsible for the gas turbine package upgrade to ensure safe operation with hydrogen fuel. DLR and the universities, Lund (Sweden), Duisburg-Essen (Germany), and University College London (UK), contributed to the hydrogen turbine technology development. Arttic supported the operational project management, while NTUA in Athens (Greece) carried out economic and environmental analysis of the concept.

“The interaction between electrolysis, storage, and hydrogen conversion at one site has been impressively demonstrated, and now it’s a matter of scaling the results,” said Karim Amin, Member of the Executive Board of Siemens Energy.
