Cortez, formerly an executive of Flour with international experience in major energy project development; Enrique Iglesia, Chancellor’s Professor of chemical engineering at the University of California, Berkeley and a renowned leader in catalysis; and Leo E. Manzer, formerly of DuPont where he directed the company’s catalysis center and now a DuPont fellow.

About Range Fuels, Inc.
Range Fuels, Inc., is focused on green energy and the production of cellulosic ethanol. The company does not use food products like corn, but rather uses waste materials and turns them into valuable products. The company's innovative technology uses wood chips, municipal waste, paper pulp, olive pits, and more and converts those materials to ethanol. The company's system, named K2, uses a two step thermo-chemical conversion process. The first step converts the biomass to synthesis gas and the second step converts the gas to ethanol. The company's business model is to design, build, own and operate its plants. The company is privately held and funded by Khosla Ventures, LLC, arguably the top venture firm in the U.S. focusing on alternative, green energy systems. The leadership team melds experience from Silicon Valley's fast-paced, high-tech world, and the technologically intense coal, coal gasification, and gas-to-liquids industries.
