OXCCU Reports a Fuel Blendstock Milestone in Intertek Tests

OXCCU says its pilot aviation-fuel blendstock passed Intertek tests of properties required under ASTM International's D7566 Annex A4. The October 21 result concerns Fischer-Tropsch synthesized kerosene with aromatics. This pathway permits up to 50 percent blending by volume; the finished blend has separate qualification requirements. OXCCU expects its larger OX2 facility to be fully operational in early 2027. The milestone establishes a reported fuel-quality result as the company works toward larger production. [1] [2] [3]

The potential emissions saving depends on the supply chain. In a 2025 study, Aron Bell and colleagues modeled comparable carbon-dioxide-to-jet-fuel routes in Spain at roughly 11 to 101 grams of carbon dioxide equivalent per megajoule of fuel energy (gCO2e/MJ), against ICAO's fossil-jet baseline of 89. The study used renewable-powered electrolytic hydrogen throughout, while varying carbon sources and electricity for other operations. One case using low-temperature direct air capture and renewable electricity reached 12.3 gCO2e/MJ, about 86 percent below that baseline. Its fuel-cycle boundary covers capture, production, transport and combustion, excluding plant construction. These are modeled comparisons; OXCCU's announcement reports property tests. [4] [5]

Combustion returns the captured CO2 to the atmosphere. Air or biogenic CO2 can recycle recently circulating carbon; fossil point-source CO2 retains its fossil origin. Electricity-intensive hydrogen production also makes the power supply decisive. For illustration, replacing half a fuel supply's energy with the modeled 12.3-g fuel would yield about 51 gCO2e/MJ, a 43 percent lifecycle reduction. That calculation describes a hypothetical energy blend, with no claim about an approved OXCCU product. Industry-wide savings would depend on how much low-emissions fuel replaces fossil kerosene, and on the clean electricity and hydrogen available to produce it. [4] [6]
