Fueling the transition to carbon neutrality

Synthetic natural gas (SNG) or biogas have the same low NOx, SOx, and particulate matter emissions as natural gas, and they can be carbon-neutral depending on the feedstock and conversion energy source. Both can be blended with natural gas to reduce the carbon footprint in power generation.

They also reduce dependance on the fluctuations of the natural gas market. Another advantage is that the existing natural gas infrastructure can be used to transport and store SNG or biogas. A power plant running on gas causes approximately 50% fewer carbon emissions than one burning coal. Emissions can be further reduced with high efficiency solutions. SNG or biogas can make the process carbon neutral.
Future fuel SNG / Biogas

Multiple power and heat applications for SNG or biogas

The use of alternative fuels such as SNG or biogas is now made even more relevant by the rising prices and declining availability of natural gas threatening security of supply.

MAN dual fuel and gas engines are perfectly suited for generating power and heat from 100% SNG or biogas, or blends. The highly efficient engines include two-stroke and four-stroke, gas, and dual fuel models. You can use them for base-load, peaking or combined heat and power.

The differences between
SNG and biogas

The differences between SNG and biogas lie in what they are made from and how they are made. SNG can be produced using renewable or surplus energy in power-to-gas systems. SNG can also be derived from fossil fuels and biomass via gasification and methanation processes. Biogas is produced from biomass and waste products by purification.

Converting renewable electricity into storable fuels spreads the benefit of carbon-neutral energy across sectors. In a power-to-X process, green energy is turned into green hydrogen via electrolysis, which is in turn converted into carbon-neutral synthetic fuels. MAN Energy Solutions and its subsidiary H-TEC SYSTEMS are experts in manufacturing proton exchange membrane (PEM) electrolyzers for this purpose.

With our MAN DWE ® Reactors we provide the methanation reactors to produce SNG from green hydrogen.

MAN 12V/3544G TS engines for German CHP

Schwäbisch Hall

MAN 12V35/44G TS for Schwäbisch Hall

MAN Energy Solutions commissioned the new combined heat and power plant in the town of Schwäbisch Hall in southern Germany. We supplied two MAN 12V35/44G TS gas engines to replace the plant’s two 3MW engines. The CHP plant now achieves a fuel efficiency of up to 90% and an electrical efficiency of 47%. Schwäbisch Hall also uses biomethane as fuel, reducing its dependence on natural gas supplies.
