- In 2007, UOP Honeywell released the Ecofining™ Advanced Synthetic Biofuels Process. The Econfining™ process uses vegetable oils, animal fats & greases as the primary feedstock to manufacture environmentally responsible, clean advanced synthetic “tank-ready” diesel and aviation fuel.
- Gas Technology Institute (GTI) invented, tested, and patented the IH2® process. The process converts wood and other non-food cellulosic biomass feedstocks directly into environmentally responsible, clean advanced synthetic gasoline, diesel and jet "tank ready" fuels.
In 2009, initial bench scale (12kg/day) testing of the IH2® Advanced Synthetic Biofuels Process began.
In 2011 GTI signed Shell Global subsidiary CRI Catalyst Company as the exclusive worldwide licensor for IH2® technology.
In 2012 GTI’s relationship with Shell Global, combined with DOE funding, enabled the rapid development of the IH2® technology from initial proof-of-principle experiments through continuous testing in a 50 kg/day pilot plant at GTI in Des Plaines, Illinois. This also provided support for engineering work to design a 1 ton/day demonstration unit and techno-economics for a commercial-scale 2,000 ton/day unit.
In 2012 Michigan Technological University performed an intensive “cradle-to-grave” Life Cycle Assessment of the IH2® process greenhouse gas emissions (GHG). The main conclusion from the study is that GHG emissions for production and use of IH2® biofuels represent a 93-98% reduction in comparison with petroleum fuels. This is cleaner than electric vehicles which represent an estimated 50% GHG emissions in comparison to petroleum fuels.
In 2017 Shell India Markets Pvt Ltd (SIMPL) built a 5 ton/day IH2® Demonstration Plant in Bangalore, India.
