Hydrogen as Climate-Friendly Alternative to Fossil Energy Sources

For the energy transition and climate protection, hydrogen (H₂) is one of the key instruments to effectively reduce emissions from energy generation. Where produced in a climate-friendly way, the versatile fuel is a compelling, sustainable, and efficient alternative to fossil energy sources such as coal, oil, and natural gas. The European Union intends to achieve climate neutrality by 2050. For this, Europe’s carbon emissions from energy generation need to be reduced significantly. To achieve the defined climate goals, the energy consumption, too, must be brought down, e.g. via flex operation of cogeneration power plants. New laws and regulations including the 44^th Federal Immission Control Ordinance (44^th BImSchV) determine stricter emission limits for plants with firing systems, gas turbines, and combustion engines, which plant operators need to comply with. Also, they need to furnish evidence of their compliance with these laws and regulations. The National Hydrogen Strategy also provides for the speedy development of hydrogen technologies and assurance of international market availability for the production and use of hydrogen in order to make the amount of hydrogen required for the conversion of the respective application areas available as soon as possible.

Sustainably produced green hydrogen can used as a climate-friendly energy source for distributed power generation with gas engines, as fuel for vehicles, as raw material for chemical processes, and for long-term storage.

Green and Blue Hydrogen: Climate-Neutral Fuel and Energy Store

Compared to fossil fuels, the carbon emissions of sustainably produced hydrogen are much lower. About 96 percent of the hydrogen produced around the globe is produced from natural gas, oil, and coal. Distinction is made between green, blue, turquoise, and gray hydrogen.
Green hydrogen is produced via electrolysis using renewable energies, while blue hydrogen is produced using the steam reforming method in which the CO₂ is captured and stored. At the bottom line, the production of both types of hydrogen is carbon-neutral.

Hydrogen Approved for Use as Fuel for MWM Gas Engines

Besides the benefit of lower emissions, the use of hydrogen also affects the efficiency, initial investments, fuel and maintenance costs, and the material quality of the piston engines. The properties of hydrogen give rise to a number of structural requirements that must be met and that are vital for products that support hydrogen. For example, this includes a wide range of flammability (enables lean mixtures), high autoignition temperature (similar to methane), low ignition energy (risk of premature ignition and flashback), and potential material incompatibilities (embrittlement of the steel). The developers of the MWM gas engines have mastered these challenges through ongoing research.

Green Hydrogen as Clean Fuel for MWM Gas Engines and Cogeneration Power Plants

MWM has extensive experience in the use of gas engines with hydrogen admixture. Through the deployment of various MWM products and technologies in customer projects, MWM has implemented trend-setting projects with a hydrogen content of up to 60 percent.

MWM gas engines are already suitable for operation with a hydrogen admixture of up to 10 vol% without any technical modifications. Higher hydrogen admixtures of up to 25 vol% are also possible with MWM gas engines of the TCG 3016 and TCG 3020 series. For this, however, technical modifications are required in order to ensure safety and optimum performance and efficiency of the energy generation.

Investments in new and replacement cogeneration power plants that enable the use of hydrogen

For customers who want to invest in new engines for continuous operation, base load supply, or peak load operation, MWM will introduce gas engines that can run on natural gas with a hydrogen admixture of up to 25 vol%.

The new TCG 3016 and TCG 3020 gas engines introduced by MWM can be operated with a hydrogen admixture of up to 25 vol%. With its offering, MWM enables plant operators to switch to more climate-friendly fuels while preserving their plants’ long-term economic viability.

MWM retrofit and conversion offering for existing cogeneration power plants

For customers who want to upgrade their plants for the use of hydrogen, MWM offers retrofit kits for the gas engines of the TCG 3016 and TCG 3020 series in order to enable hydrogen admixture of up to 25 vol%. The MWM 25H2-Kit for existing plants with TCG 3016 gas engines is offered in two editions: Depending on their needs, plant operators can convert their gas engines of this series for operation with a hydrogen admixture of up to 20 vol% or up to 25 vol%. With the MWM 25H2-Kit for retrofitting existing plants, plant operators can upgrade their gas engines of the TCG 3020 series for operation with a hydrogen admixture of up to 25 vol%. With this offering, MWM facilitates the transition to plant operation with hydrogen admixture, thereby boosting operational efficiency and reducing emissions.
