With the joint-demonstration project "H2GT-Lingen", German energy company RWE Generation SE and Japanese comprehensive heavy-industry manufacturer Kawasaki Heavy Industries are planning to install a hydrogen-fueled gas turbine based on renewable green hydrogen in Lingen, Germany. The gas turbine generator set "GPB300 / L30A" with an electrical power output of 34 MWei. will be used to reelectrify hydrogen. H2GT-Lingen will be one of the world's first pilots to test 100% hydrogen-to-power conversion on an industrial scale turbine.At the site of its gas-fired power plant in Lingen, RWE intends to generate green hydrogen with electrolysers powered by renewable electricity. The company is planning to build a first 100-MW electrolysis plant in Lingen by 2024, which is to be expanded to 2 GW by the end of the decade.Kawasaki's gas turbine provides the maximum possible fuel flexibility. It can operate with 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 H2GT-Lingen project. The diffusion flame combustor will use water injection to achieve low emissions. In a subsequent phase, the installed diffusion flame combustor will be replaced by a Micro-Mix DLE combustor (MMX-combustor).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.'
