Denver, CO. 21 June 2019. Boom Supersonic, the Colorado company building history’s fastest supersonic
airliner, announced a unique partnership with Prometheus Fuels. Prometheus will supply fuel during the flight
test program of XB-1, Boom’s Mach-2.2 demonstrator aircraft. Boom plans to use Prometheus fuel to power XB-1
in the world’s first supersonic flight using carbon-neutral fuel.
Through a process called direct air carbon capture, Prometheus removes carbon dioxide (CO2) from the air and uses
clean electricity to transform it into gasoline, diesel, and jet fuel. The electricity used in this process comes from
renewable sources such as solar and wind, so there are no net carbon emissions from using the fuel.
“Boom is committed to making supersonic travel environmentally sustainable—we want society to enjoy the benefits
of faster flight for generations to come. Prometheus is doing incredible work, and we are thrilled to partner with
them to accelerate the deployment of alternative aviation fuels,” said Blake Scholl, founder and CEO of Boom. “We
couldn’t be more excited to have them as a fuel supplier.”
At Prometheus, our goal is to replace fossil fuels with our high performance zero-net carbon fuels, made from CO2
that’s already in the air” said Prometheus founder and CEO, Rob McGinnis. “We believe it’s possible to solve global
warming with innovation, and to push human achievement higher and faster while we do it. We’re proud to partner
with Boom to do just that.”
XB-1 is nearing completion and will help refine the design and engineering of Overture, Boom’s revolution-
ary supersonic commercial airliner. XB-1 shares the same key technologies as Overture: advanced carbon fiber
composites, a refined delta wing planform, and an efficient variable-geometry propulsion system. Lessons from
XB-1 have already helped optimize Overture and will prove in-flight key technologies for safe, efficient travel at
Mach 2.2.
