Green hydrogen opens the door to net zero

Green hydrogen is CO2-neutral because it is made using renewable energy, as opposed to blue and gray hydrogen, which are made from fossil fuels. Together with its derivatives, green hydrogen offers solutions for the decarbonization of many industrial sectors, and is especially important where direct electrification is not possible. MAN Energy Solutions provides holistic hydrogen solutions, enabling both the production of green hydrogen from renewable energy sources and the utilization of green hydrogen and its derivatives as net-zero fuels.

Hydrogen offers new ways
to decarbonize

Hydrogen and its derivatives offer decarbonization options for the process industry, transportation, and power and heat supply where electrification is not an option. Industrial processes that run on hydrogen, ammonia, and methanol of fossil origin can change to green alternatives.

One example is the production of green steel using green hydrogen, which lowers emissions by 30-40%. In power and heat supply, our medium-speed gas engines can currently be operated with up to 25% hydrogen admixture. Synthetic natural gas allows the CO2-neutral operation of ships and power plants by using the existing infrastructure.

Hydrogen extraction and conversion

In electrolysis, the energy of the sun, water or wind is converted into hydrogen. The proton exchange membrane electrolysers (PEM electrolysers) used for this process are manufactured by MAN Energy Solutions and its subsidiary H-TEC SYSTEMS.

The resulting green hydrogen is then either stored, used directly as a fuel, mixed with natural gas, or converted into other fuels such as synthetic natural gas (SNG), green ammonia or green methanol using the power-to-X process. MAN DWE® offers reactors for these hydrogen-to-X processes.

MAN hydrogen solutions

MAN gas-powered engines are H2-ready and operable in stationary mode with a hydrogen content of up to 25% by volume in a gas-fuel mix. This includes the MAN 35/44G TS, 51/60G and 51/60G TS gas engines. 100% H2 combustion is in development.

MAN 51/60G

The MAN 51/60G offers superior performance with its two-stage turbocharging. Offering best-in-class performance and low emissions, it sets new standards for gas engines.

SNG as a short- and
medium-term measure

Until processes have been adapted to hydrogen, SNG is a CO2-neutral alternative to natural gas for the transition period. Currently, SNG made from hydrogen can be used in natural-gas-powered applications with minimal adaptation. Operators save on CO 2 and can enhance their environmentally friendly reputation. Long-distance shipping is a good example of an application that cannot be simply electrified with batteries but where SNG is practical.

New German CHP Plant to Save 50,000 Metric Tons of CO2 Annually

MAN Energy Solutions commissions 51 MW gas-fired, combined-heat-and-power plant in Frankfurt (Oder); new facility replaces older, lignite-burning plant for excusive natural-gas operation

MAN Energy Solutions has commissioned the new, municipal (Stadtwerke) CHP (Combined Heat and Power) gas power-plant in Frankfurt (Oder). At a recent ceremony, Dr Uwe Lauber, CEO of MAN Energy Solutions, symbolically handed the plant over to Torsten Röglin, Managing Director of Stadtwerke Frankfurt (Oder), and René Wilke, the city’s Lord Mayor.

The CHP plant is powered by 5 × MAN 20V35/44G gas engines, which provide 51 MW of electrical energy as well as 50 MW of district heating. In addition, MAN has installed a hot-water boiler with a capacity of 20 MW, increasing the total thermal capacity of the plant to 70MW. Despite constant challenges due to the Covid-19 pandemic over the past two years, MAN and Stadtwerke Frankfurt (Oder) were able to complete the commissioning within the estimated schedule. The five engines have been test-run since mid-February of this year.

The new, gas-engine power plant replaces an older, soon-to-be-retired CHP plant, which has supplied electricity to around 33,000 households and commercial customers – as well as district heating to around 19,000 households and companies – locally since 1997. Previously, this plant was operated with both lignite and natural gas, while the new facility will supply the same distribution network with heat and electricity generated exclusively from the more climate-friendly natural gas.

Efficiency over 90%

“Through introducing this new plant, we will save up to 50,000 metric tons of CO2 annually in the future, thus ensuring the environmentally-friendly supply of heat and electricity to the Frankfurt (Oder) region,” said Torsten Röglin. “In the old power plant, around 60,000 tons of brown coal dust were burned annually. In contrast, the new plant not only exclusively uses natural gas, which is more climate-friendly, but is also particularly fuel-efficient with an overall efficiency of more than 90%.”

Stadtwerke Frankfurt (Oder) has invested a total of almost 60 million euros in the power plant, representing the company's largest investment project in the last 20 years.

“The military attack on Ukraine by the Russian government, which is contrary to international law, is currently causing many people to view natural gas sceptically as an energy source,” said Dr Lauber. “However, we have to separate the question of the origin of the raw material from that of the technology. Flexible, gas-fired power plants like the new combined-heat-and-power plant in Frankfurt are an indispensable technology on the way to the energy and heat transition. We need such facilities to reduce greenhouse gas emissions, phase out coal, and partner renewable energies.”
Lauber continued: “With this new, combined-heat-and-power plant, Stadtwerke Frankfurt (Oder) is proving that cogeneration with district heating is a viable, long-term, economic concept for the immediate reduction of CO2 emissions that simultaneously ensures reliable electricity and heat supply to the local population.”

MAN Energy Solutions states that plant emissions can be reduced even further by operating the engines with a mixture of green hydrogen and natural gas, while completely climate-neutral operation is possible when operating with hydrogen-based, synthetic natural gas (SNG).

Gas engines ideal for district heating

The MAN 20V35/44G gas engines optimise the flexibility of the entire CHP plant. In combination with a 10,000 cubic-meter heat-storage facility, also newly built, waste heat from the engines can be stored when heat demand is low while continuing to generate electricity. This enables Stadtwerke Frankfurt (Oder) to react quickly and flexibly to price fluctuations in the electricity market. This is also supported by the high reaction speed of the MAN engines, which can reach full output in less than five minutes and easily cope with rapid load changes.

Post-commissioning, MAN Energy Solutions’ global after-sales brand – MAN PrimeServ – will continue as project partner and share maintenance duties with plant staff.
