The power of green hydrogen
Hydrogen is a key element in the energy transition. It has the potential to decarbonize a vast variety of sectors, from shipping, heating and cooling to industrial applications. We at MAN Energy Solutions acknowledge the power of H2 and with our solutions and services, we are already covering all parts of the hydrogen economy today.
Prepared for change with the complete value chain of H2 and synthetic fuels
To reach carbon-neutrality in this generation, the world needs quick and efficient solutions. As a solution provider and general advisor on the question of decarbonization, we are ready to support the energy transition with full power. Our portfolio already covers the complete value chain of H2 from production to utilization – we are prepared for change.Hydrogen can be produced from renewable energy in a climate-neutral way and forms the basis for the production of a variety of synthetic fuels through Power-to-X processes. We urgently need these alternative fuels to implement the energy transition, because they make renewable energy usable outside the electricity grids. In this way, CO2 emissions can also be reduced in those areas where direct electrification is not sensible or possible, such as international shipping. Hydrogen and Power-to-X thus form an important link for the sector coupling of power and heat generation, transport and industrial applications.
Paving the way for a greener future
The production of hydrogen is the crucial first step in the value chain. H-TEC SYSTEMS, a German electrolysis-specialist, has been perfecting its technology for more than 20 years; MAN Energy Solutions recently acquired 99% of the company’s shares. H-TEC SYSTEMS offers PEM (Proton Exchange Membrane) electrolysers in the 225 kW to 1 MW range.
Together with MAN Energy Solutions, the company is now promoting the development of PEM electrolysers in the multi-megawatt range, which will also enable the use of the most pioneering electrolysers on an industrial scale.
Delivering a green future
To make CO2-neutral energy useful across all sectors, converting renewable electricity into storable and easy-to-handle fuels is crucial; the power-to-X process allows for just that. It is a transformation technology that converts renewable electricity into carbon-neutral, synthetic fuels, which can then be used in other sectors or be stored until needed. Among others, these fuels include synthetic natural gas (SNG), green ammonia and methanol.
MAN Energy Solutions is already a pioneer of power-to-X technology: in 2013, we commissioned the methanation reactor for Europe's first – and, at 6 MW, largest – power-to-gas plant. Currently, the e-gas plant in Werlte, Lower Saxony, supplies 1,500 gas-powered vehicles with climate-neutral fuel every year.
We have since consistently developed power-to-X technology and offer turnkey plants with a capacity of 50 MW and more. Such a plant can produce 14,500 tons of synthetic natural gas (SNG) per year, enough fuel for 470 natural-gas-powered, local-transport buses to each cover 60,000 kilometres CO2-neutrally.
As a leading provider of reactor technology, we furthermore offer sophisticated chemical-reactor systems to convert hydrogen into a broad variety of synthetic fuels, including synthetic methane, methanol and ammonia.
Solutions for hydrogen infrastructure
A viable hydrogen infrastructure requires that hydrogen is transportable from source to point of use. This can happen via pipeline, by road in gaseous tube trailers, as well as by rail or ship. In order to transport large volumes of hydrogen, it must be pressurized and delivered as a compressed gas. This is where our turbomachinery technology comes into play with MAN’s high-tech compressor solutions being capable of installation, for instance, in future H2 pipeline compressor-stations. Additionally, MAN Energy Solutions already has expertise in building turnkey, turbomachinery systems for large industrial plants that produce ammonia and methanol, both of which viable carriers for hydrogen.
The future is here
At MAN Energy Solutions, we are helping to shape the sustainability agenda and provide a clear path for you to achieve your goals. That’s why we believe in a broad field of application for H2 and synthetic fuels – whether applied to power-and-heat generation, shipping, steel or cement production, or other industries. No matter what vessel or plant you operate, our proven, fuel-flexible engines and solutions are future-proof and ready for the climate-neutral fuels of the future.
We cover all processing steps of the hydrogen economy under the umbrella of MAN Energy Solutions.

Stationary engines of MAN Energy Solutions ready for green future fuels
In continuously developing the range of services for its portfolio of four-stroke engines, MAN Energy Solutions enables its customers to exploit a multitude of synthetically manufactured, climate-neutral fuels in the operation of ships or power plants. Already today, MAN engines using power-to-X fuels such as synthetic natural gas (SNG) can be operated totally climate-neutrally.
MAN customers will in due course be able to use other, so-called 'future fuels' –such as ammonia, methanol and hydrogen – also produced in a climate-neutral manner. While these fuels are not currently available on the market, their use in MAN units will, however, be possible through the incipient start-up of green-fuel production facilities. These, in turn, will further reduce harmful emissions and reliably meet future, stricter environmental requirements and regulations.
The company's 35/44G TS, 51/60G and 51/60G TS gas engines relevant for use in power stations are already 'H2-ready' and can be operated with a hydrogen proportion of up to 25% by volume in the gas mixture. By 2025, the units should also be updated and capable of operation on 100% hydrogen.
The 51/60DF and 51/60DF TS multi-fuel engines’ CO2 emissions can be additionally reduced through the use of biofuels. "Full operation with biofuels has already been tested in the field and is possible without any problems," said Alexander Stöckler, Head of the Power Plant Division at MAN Energy Solutions. Similarly, MAN engineers are preparing grounds for operation on ammonia and methanol by the end of 2022.
"We are currently working on a realization concept for operation on ammonia and methanol and are confident that we will begin to implement this by the end of 2022," explained Stöckler. "As of yet, neither fuel plays a role in energy generation but they may have significant potential for the future. Therefore, we are observing the situation very keenly and are in close communication with our customers. As soon as our customers are ready, our engines will be too."
Even now, engine power stations with combined heat and power are already making a considerable contribution to climate protection. "Modern plants already achieve overall efficiencies of over 90% when operating with traditional natural gas," added Stöckler. "By gradually adding hydrogen, SNG or alternative fuels, the climate footprint of such plants can be reduced even further. We will also make the conversion of existing plants to full operation with future fuels possible."
MAN Energy Solutions traditionally follows a life cycle concept, which the company also sticks to when it comes to future fuels. "In addition to new-engine business, we are also always thinking in terms of retrofitting the existing fleet," said Bernd Siebert, Head of Four-Stroke Retrofitting at MAN PrimeServ, MAN Energy Solutions’ after-sales brand. "Power plants have a lifetime of several decades. After retrofitting, engines already in the field have the same capabilities as our new engines. This is how we safeguard, not only the climate, but also our customers’ investment."
