ONE OF THE WORLD’S FIRST 100% HYDROGEN-TOPOWER DEMONSTRATIONS ON INDUSTRIAL SCALELAUNCHES IN LINGEN, GERMANY

Hydrogen-to-Power Plant in Lingen
Tokyo and Lingen, December 9, 2021 — With the joint-demonstration project “H2GTLingen”, German energy company RWEGeneration SE (RWE) and Japanesecomprehensive heavy-industry manufacturer Kawasaki Heavy Industries (Kawasaki) areplanning to install a hydrogen-fueled gas turbine based on renewable green hydrogenin Lingen, Germany. The gas turbine generator set “GPB300 / L30A” with an electricalpower output of 34 MWel. will be used to reelectrify hydrogen. H2GT-Lingen will be oneof the world’s first pilots to test 100% hydrogen-to-power conversion on an industrial
scale turbine.
In order to become climate-neutral by 2040, RWE is planning to switch its gas-fired
power plants from natural gas to hydrogen over time, as one option for decarbonisation.
With H2GT-Lingen, RWE is gaining experience in operating a hydrogen-fired turbine.

At the site of its gas-fired power plant in Lingen, RWE intends to generate greenhydrogen with electrolysers powered by renewable electricity. The company is planningto build a first 100-MW electrolysis plant in Lingen by 2024, which is to be expanded to2 GW by the end of the decade.
Kawasaki’s gas turbine provides the maximum possible fuel flexibility. It can operatewith 100% hydrogen, 100% natural gas and with any combination of both. This
flexibility will be indispensable, as during the initial phase the amount of hydrogen
available for reconversion will fluctuate over time before 100% hydrogen operation will
be possible throughout.
Kawasaki has developed two different types of combustion systems to achieve 100%hydrogen operation. One is a diffusion flame, the other a Dry-Low-Emission (DLE)
combustor. In the beginning, the diffusion flame combustor will be used for the H2GTLingen project. The diffusion flame combustor will use water injection to achieve lowemissions. In a subsequent phase, the installed diffusion flame combustor will bereplaced by a Micro-Mix DLE combustor (MMX-combustor).
Using hydrogen in conventional DLE combustors increases NOx emissions and heightens
the risk of flashbacks. Hence established gas turbine DLE combustion systems cannot
be directly used. The development of DLE hydrogen combustion technologies is thus
essential for pure hydrogen (100 Vol%) combustion and Kawasaki has therefore
developed the innovative and unique MMX-DLE combustor.
The hydrogen combustors that have been developed were successfully tested in 2018as part of the demonstration power plant project “Hydrogen CGS for Smart Community
at Kobe” for the 1 MW gas turbine category in Japan. The “H2GT-Lingen” project aims
to scale up these proven technology principles.
The hydrogen-powered gas turbine is scheduled to be operational in mid-2024.

The rapid global expansion of renewable energies over the past few decades has led to
newchallenges forconventional

power

generation systems.

Tomanagetheintermittency of renewable energy, flexible power generation systems and energy
storage systems are becoming increasingly important. During the transition period, gas
turbine technologies will play a vital role in stabilising power supply. Accordingly, in thecourse of the H2GT-Lingen project different operational load ranges between 30% and100% will be tested to increase operation flexibility. This will become very important tocompensate for fluctuations in the grid resulting from the volatile availability ofrenewable energies.
Recently it has become essential to pay full attention to de-carbonisation andsustainability in all industrial sectors. Hydrogen, produced using wind and solar energy,
can replace climate-damaging fossil fuels as an alternative for gas turbines, thus
enabling low-emission power generation in the future. Both RWE and Kawasaki are thus
convinced that hydrogen fuels will be key components of a sustainable de-carbonised
society.

The H2GT-Lingen project will demonstrate the suitability and importance of hydrogen
fueled gas turbines for the global energy transition.
