Producing Alternative Transportation Fuels (including SAF) From Renewable Resources With IH^2®

As global demand for power and fuels grows, drop-in liquid fuels will play an increasingly impactful role in achieving lower emissions and delivering energy security. By integrating advanced fuels, we create a robust and adaptable energy ecosystem that can meet industrial-scale performance and reliability needs for all.

GTI Energy invented IH^2®, an integrated hydropyrolysis and hydroconversion catalytic thermochemical process. It converts non-food biomass feedstocks—such as wood, agricultural residues, algae, aquatic plants, and municipal waste—directly into SAF (sustainable aviation fuel), gasoline, and diesel drop-in transportation fuels with greater than 60% reduction in greenhouse gas emissions.

U.S. Department of Energy funding enabled early stage development of the IH^2® technology, from initial proof-of-principle experiments through continuous testing in GTI Energy’s 50 kg/day pilot plant (IH²-5). The IH²-50 pilot plant has achieved cumulative operation in excess of 15,000 hours and subsequently was the basis for early engineering work to design commercial-scale plants.

From 2010 to 2024, GTI Energy and Shell Catalysts and Technologies worked together to progress commercial readiness of the IH^2® process, through a publicly reported 5 ton per day (TPD) IH^2® demonstration plant in Bangalore, India.

The fully integrated IH^2® technology is patented and to date, 13 U.S. patents and their foreign equivalents relating to the technology are owned by GTI Energy.
