GENERATION
EnviTec Biogas sees biomethane market on the upswing across Europe, also due to coalition agreement
EnviTec Biogas sees great growth potential in the biomethane market, fuelled by the EU's REPowerEU plan and the new coalition agreement in Germany. The company is investing around EUR 200 million in the expansion of its plants and is increasing biomethane production to 400 GWh per year. According to EnviTec, biomethane offers a wide range of opportunities to replace fossil natural gas, particularly in the heating and fuel sectors and in industry. EnviTec is now calling for decisive political action to support the energy transition in order to further develop the market.

MOBILITY
Keel laying of a new ferry with gas-electric propulsion based on biomethane
The district of Lüneburg is currently having a new Elbe ferry with a gas-electric biomethane drive built at the Hitzler shipyard - a first in Germany. The new ‘Amt Neuhaus - Bleckede’ is replacing its 80-year-old predecessor and will transport larger vehicles across the Elbe faster and in a more climate-friendly way. With an investment volume of EUR 6.8 million and almost 50 tonnes of steel, the project is also technically ambitious. Completion and commissioning are planned for early 2026.

Verbio and Iveco plan truck leasing offer for biomethane-powered vehicles
Verbio and Iveco Nord-Ost are offering haulage companies a new combined offer of truck leasing and discounted biomethane supply. Companies that lease an LNG or CNG-powered S-Way tractor unit receive bio-LNG or bio-CNG at fixed, favorable conditions for the entire term of the contract - cheaper than fossil diesel. The biomethane comes from agricultural residues and is made available at over 30 own and partner filling stations throughout Germany. The aim of the cooperation is to make the introduction of alternative drives in long-distance and distribution transport economically attractive and climate-friendly.

HEAT
enercity plans heat transition with biomethane CHP in Hanover
By 2027, the energy supplier enercity will replace its coal-fired power plant in Hanover-Stöcken with two state-of-the-art biomethane CHP plants, each with an output of 20 MW - the largest of their kind in Germany. The plants were built at a cost of around EUR 55 million, achieve an overall efficiency of over 90% and enable a flexible, demand-driven supply of electricity and heat. In future, the system will be supplemented by a 60 MW river water heat pump in Hanover-Herrenhausen. In this way, enercity is making a key contribution to the coal phase-out and the heat transition in the region.

Stadtwerke Ludwigsburg puts its first biomethane CHP plant into operation
Stadtwerke Ludwigsburg-Kornwestheim (SWLB) has commissioned the first of two biomethane cogeneration plants at its new Waldäcker III energy center; the second will follow in mid-April. The plant will generate around 39 million kWh of electricity and 54 million kWh of heat per year - up to 90% of which will come from renewable energies. This will increase the proportion of renewable heat in the Ludwigsburg grid from 51% to 74% and save 13,000 tons of CO₂ per year. Full commissioning and official opening is planned for May.

INTERNATIONAL
DK | 100th EnviThan plant with a total capacity of 1,510 Nm³/h commissioned
EnviTec Biogas has commissioned its 100th EnviThan gas upgrading plant in Denmark. The plant at Lars Nielsen's Lykkeslund Farm achieves a flexible biomethane capacity of 1,510 Nm³/h and efficiently processes liquid manure and residual materials for separate marketing. A new feature is the compact housing of the entire technology in just one 45' container, which saves space and costs. With 13 projects and a total capacity of almost 10,000 Nm³/h, EnviTec is a major player on the Danish biomethane market, which currently covers 37% of national gas consumption.

IT | Plenium Partners acquires EUR 25 million investment for biomethane plant near Pavia
Plenium Partners, an independent Spanish sustainable energy infrastructure investment company, has received over EUR 25 million from ING Italia to finance its first biomethane plant in northern Italy. The plant in the province of Pavia will process around 50,000 tons of agricultural waste per year from the beginning of 2026 and produce up to 500 Nm³/h of biomethane. A special feature is the complete CO₂ recovery, which further improves the carbon footprint. The project is part of a platform of four plants that Plenium is realizing together with Aragorn Value Leadership for over EUR 100 million.
IT | Anaergia and Capwatt sign letter of intent to build nine biomethane plants in Europe
Canadian waste-to-energy company Anaergia has signed a binding letter of intent with multinational energy company Capwatt to design and build nine new biomethane plants in Portugal, Spain and Italy. The plants are to be completed within 30 months and will produce 556,000 MWh of biomethane per year from agricultural waste. For Anaergia, this will result in an expected turnover of over 60 million Canadian dollars. The cooperation builds on projects already realized in Portugal and Italy and significantly strengthens Europe's biogas infrastructure.
