P2X Solutions has secured a 10-year offtake agreement for the full current production capacity of its Harjavalta methanation plant, signaling that demand for synthetic methane is beginning to move from pilot projects toward contracted fuel supply.
Under the agreement with avanca Energy and its subsidiaries avanca Renewables and Alternoil, deliveries of synthetic methane are scheduled to begin in October 2026. The fuel will be marketed as e LNG through Alternoil’s REEFUEL network for heavy duty road transport. P2X Solutions says the agreement covers the plant’s entire current methanation capacity for the next decade, with the partners targeting a potential tenfold increase in delivery volumes compared with 2026.
The agreement links a Finnish power to fuel project directly with Germany’s expanding renewable fuel distribution infrastructure. Alternoil operates a nationwide renewable LNG network, providing an existing route into the heavy truck market rather than requiring e methane producers to establish a new fueling system.
P2X Solutions produces the synthetic methane at Harjavalta by combining green hydrogen with captured carbon dioxide. The process converts renewable electricity into a gaseous fuel that can be handled through infrastructure and vehicle systems designed for natural gas and LNG.
That compatibility is commercially important. Heavy duty trucking is increasingly electrifying, but long haul operations still face challenges around charging infrastructure, vehicle utilization and payload requirements. E methane can potentially use existing gas based vehicle and fueling infrastructure, although its competitiveness will depend heavily on electricity costs, carbon sourcing, regulatory treatment and the efficiency of the power to methane conversion chain.
The Harjavalta agreement therefore provides more than a sales contract. It gives the project a long term demand signal while giving avanca and Alternoil access to a domestic European source of synthetic methane.
P2X Solutions is also positioning Harjavalta as the first step in a larger synthetic fuel portfolio. The company says it aims to develop multiple facilities producing green hydrogen and synthetic fuels, including e methane, e methanol and e ammonia, with a longer term objective of reaching 1 GW of hydrogen production capacity.
Germany’s revised transport fuel policy provides another potential source of demand for renewable hydrogen derivatives.
In April 2026, the German Bundestag approved an expansion of the country’s greenhouse gas reduction quota for transport fuels, raising the required emissions reduction progressively to 65% by 2040. The legislation also introduced a specific requirement for renewable fuels of non biological origin, including green hydrogen and synthetic fuels, rising to at least 8% by 2040 according to the International Energy Agency.
This creates a regulatory market for synthetic fuels, but it does not guarantee that e methane will dominate it. The German framework is technology neutral and allows multiple pathways to contribute toward the transport decarbonization targets. E methane must therefore compete with battery electric vehicles, hydrogen, renewable fuels and advanced biofuels for both customers and compliance value.
That competition is particularly relevant because synthetic methane remains energy intensive to produce. Renewable electricity must first be converted into hydrogen and then combined with carbon dioxide to produce methane, introducing additional conversion losses compared with direct electricity use.
For applications where direct electrification is difficult, however, the value proposition can be different. Heavy duty transport operating through existing LNG infrastructure provides an immediate potential market for a fuel that can be distributed without rebuilding the entire fueling system.
The 10 year agreement demonstrates that an industrial customer is prepared to contract synthetic methane production over an extended period, but the current plant remains small relative to Europe’s overall transport fuel market.
P2X Solutions’ stated objective of increasing deliveries tenfold from the 2026 level illustrates the gap between early commercial projects and the scale required for meaningful fuel substitution.
The next challenge is therefore not simply securing additional offtake agreements. It is lowering production costs, securing sustainable carbon dioxide sources and expanding renewable electricity and electrolyzer capacity sufficiently to make synthetic methane competitive at larger volumes.
For Finland, the commercial logic is closely tied to its renewable electricity resources and its potential role as a producer of hydrogen based fuels for European markets. For Germany’s trucking sector, meanwhile, the value of e methane will increasingly be determined by how regulatory incentives, fuel prices and vehicle technology evolve.
