US project developer Infinium has taken a final investment decision (FID) on an e-fuels production plant in Texas, and has selected compatriot Electric Hydrogen to provide 100MW of proton exchange membrane (PEM) electrolyser capacity.
Construction of Project Roadrunner, at Pecos, west Texas is underway, with commercial production due to start in 2027, Infinium said.
The facility will make 23,000 t/yr of synthetic aviation fuels (e-SAF) and other e-fuels, specifically e-diesel for trucking and maritime industries and e-naphtha. This will make it the largest e-fuels facility in the world, Infinium said.
Supply will be sold domestically and exported to international markets, it said.
Infinium last year struck a 10-year offtake deal with UK-based International Airlines Group (IAG) for delivery of 75,000t of e-SAF to any of the group's airlines: Aer Lingus, BA, Iberia, Level and Vueling. The UK will introduce mandatory e-SAF quotas for the aviation sector from 2028, with the EU to follow suit in 2030.
The 7,500 t/yr deal with IAG would cover roughly one-third of Project Roadrunner's expected output. Infinium also has a supply agreement with American Airlines, the developer said.
Project Roadrunner will be fed with 150MW of wind power generation capacity from a subsidiary of Florida-headquartered NextEra Energy Resources, via a long-term power purchase agreement.
Infinium said Electric Hydrogen's integrated 100MW PEM plant "will not only produce hydrogen for the e-SAF facility but will also have capacity to support future hydrogen offtake opportunities."
Canadian asset management Brookfield in 2024 agreed to invest $200mn in Infinium, and specifically Project Roadrunner, in the short term, with potential further investments of $850mn for future projects. Project Roadrunner previously received conditional funding commitment of $75mn from the Bill Gates-founded Breakthrough Energy Catalyst.
Infinium has not specified whether it intends to avail itself of the 45V hydrogen production tax credits, which could yield up to $3/kg of hydrogen. Start of construction would leave this possibility open even if a bill proposed by Republicans in the US House of Representatives goes through. The proposed bill foresees that tax credits would only be available for projects that start construction before the start of 2026.
