    Research output: Contribution to journalJournal articleResearchpeer-review


    BioGasol is a combined biotechnology and engineering company in the field of renewable energy. The core competences lie in the development and design of process technologies for the production of bioethanol and other energy products from lignocellulosic biomasses. BioGasol has developed proprietary technologies within pretreatment, biogas production and a unique C5-fermentation for maximum ethanol production. The BioGasol concept is a well integrated technology with more than 90% utilization of the energy potential in the biomass. The production of other biofuels such as methane and hydrogen adds value to the overall process benefit. The technology can be used for green field plants or for bolt on plants to existing first generation ethanol plants. Using the yields obtained in the pilot plant 1.36 USD per Gallon is a valid estimate of the Minimum Ethanol Sales Price (MESP) for the N-th plant and BioGasol believes that its current development projects will reduce the MESP to about 1.0 USD per Gallon. BioGasol is currently building a feedstock flexible plant on the island of Bornholm in Denmark that will demonstrate how the process concept can be cost efficient adapted to the low cost available feedstocks in the region. BioGasol has a partnership with Tate & Lyle on the conversion of residual corn fibres into more ethanol. Furthermore in collaboration with Pacific Ethanol BioGasol will build a 2.7 mn Gallon cellulosic ethanol plant co-located with an existing corn to ethanol plant on the US North West Coast.
