Dimensional Energy

Dimensional Energy is a solar-to-fuel startup, producing sustainable aviation fuel (SAF) by utilizing carbon dioxide (CO2) and concentrated solar energy. The company’s innovative reactors convert CO2 into a feedstock chemical, which is further processed into sustainable aviation fuel (SAF) for the aviation sector. The company’s pilot reactor is deployed at Arizona for scaled-up testing.

In February 2024, Ampaire successfully completed the first ground test using pure 100% ASTM D7566 SAF produced by Dimensional Energy.

Key customers and partnerships

In June 2022, United Airlines signed a commercial agreement with Dimensional Energy to purchase at ~300 million gallons of SAF over 20 years. In August 2022, Dimensional Energy partnered with Heliogen, to produce SAF from concentrated sunlight and green hydrogen, following the company’s agreement with United Airlines in June 2022 to supply at least 300 million gallons of SAF. In May 2023, the company signed a SAF offtake agreement with Boom Supersonic, a commercial airplane manufacturer, to supply up to five million gallons of SAF per annum.

Funding and financials

Dimensional Energy’s most recent funding was in December 2023 when the company raised USD 20 million in a Series A financing round led by Envisioning Partners. The company planned to use the funds to construct the world’s first advanced power-to-liquid (PtL) fuels plant in partnership with Svante in Canada. Prior to this, in September 2023, Dimensional raised USD 19.7 million in funding. The company did not disclose how the funds were to be used. Previously in February 2022, Dimensional Energy received USD 3.1 million from the US Department of Energy to develop chemical reactors that convert CO2 into a chemical feedstock from 3D printing additive manufacturing systems.

In October 2021, the company was awarded USD 2.7 million by the US Department of Energy Solar Technologies Office, to develop sustainable solutions by 2035. The project involves collaborating with Heliogen and Oakridge National Labs to scale up its existing solar reactor to accept 150 kilowatts of concentrated solar power.
