Company Description: HutanBio is a climate tech company developing the world’s first sustainable fuel for aviation, shipping, and heavy transport that can compete on cost, at scale, without compromising on sustainability. These markets underpin over $40 trillion in global trade and are among the fastest-growing sources of global emissions – yet no existing low carbon fuel solution has managed to be cheap, scalable, and genuinely sustainable at the same time. Until now.
Our breakthrough HBx bioenergy technology is built on Sphaerica, a new-to-science genus of marine microalgae with unprecedented biological performance: 3× higher oil productivity than previously known algal strains in enclosed photobioreactor systems, exceptional CO₂ capture, and resilience to high salinity and solar intensity – eliminating the need for arable land or freshwater.
HutanBio is headquartered in Cambridge, UK, with R&D facilities in Malaysia and an operational footprint in Oman.
