MAN Energy Delivers Pre-FEED for Methanation Reactor, Power-to-X Plant

MAN Energy Solutions will provide the pre-FEED for a methanation reactor at StormFisher Hydrogen’s large-scale, 200-MW power-to-x plant, to be built in North America. Under the agreement, MAN Energy will test the methanation reactor technology at its facility in Deggendorf, Germany, aiming to improve methane purity by reducing unreacted components in the e-methane output. The plant is expected to produce 2.5 million MMBtu of e-methane per year, equivalent to about 50,000 metric tons of LNG.

“With this project, MAN Energy Solutions reinforces its position in methanation for power-to-x applications,” said Wagner Canelhas, Regional Sales Manager at MAN Energy Solutions Houston. “Our technology enables the smooth integration of e-Methane into existing infrastructure, reducing costs and accelerating its adoption worldwide.”

StormFisher’s plant will convert 200 MW of renewable electricity, produced via wind and solar, into green hydrogen via electrolysis. The hydrogen is then mixed with biogenic CO₂ and a catalyst to generate e-methane, which satisfies North American pipeline standards and allows the fuel to integrate within current natural gas infrastructures. e-Methane’s pipeline utilization offers decarbonization at scale with lower costs.

“The planned facility is a major component in StormFisher Hydrogen’s plans to support increasing e-fuel production capacity in North America and reinforcing American leadership in the energy sector,” said Judson Whiteside, Chief Executive Officer at StormFisher Hydrogen. “MAN Energy Solutions has the expert knowledge in methanation required to deliver the pre-FEED study to keep the project moving forward on a successful track.”

Methanation in Tampere

Earlier this year, MAN Energy Solutions Deggendorf was contracted by Ren-Gas to design, manufacture, and deliver a catalytic methanation reactor for the Tampere Power-to-Gas project. The 50-MWe methanation reactor will be installed at the Tampere e-methane plant, and in addition to design and manufacture, the company will oversee:

• Pre-fabrication
• Testing
• Installation supervision
• Commissioning
• Performance testing

Ren-Gas’ Tampere facility will generate approximately 200 GWh of renewable e-methane fuel per year for the heavy road and maritime transport industries. Also, the methanation reactor will produce 180 GWh of CO₂-free heating for Tampere’s district heating system. In terms of the e-methane production process, MAN Energy’s catalytic technology will combine approximately 40,000 tons of annually captured CO₂ from the Tarastenjärvi waste-incineration plant’s flue gases with green hydrogen.

In February 2025, MAN Energy Solutions’ 7L21/31 dual-fuel methanol (DF-M) genset passed a type approval test at CSSC Marine Power’s production facility in Zhenjiang, China. Following the successful TAT at CMP’s facility, the methanol-fueled genset received approval from major classification societies present during testing. The new methanol engine design is based on the MAN 21/31 Mk II type, which is part-load optimized with a fuel-oil consumption in the 1–2 MW range and burns heavy fuel oil/distillate and other biofuels in alignment with the ISO 8217:2024 specification. The L21/31 engine has accumulated approximately 3,000 sales over its lifetime.

According to MAN Energy Solutions, the low-cost, port fuel-injection methanol concept makes the new 21/31DF-M medium-speed, small-bore engine suitable for genset and diesel-electric propulsion applications. In a connection to underway projects, the genset is also a matching system for its methanol-fueled, MAN B&W ME-LGIM two-stroke engine.
