Japan's RITE develops cellulosic biobutanol technology

Japan's government-affiliated Research Institute of Innovative Technology for the Earth (RITE) has developed technology for the production of cellulosic biobutanol from materials such as grass cuttings and wood chips. The fuel can be blended with diesel.

Although similar technology exists for ethanol fuel for gasoline cars, this is said to be a world first for diesel vehicles.

RITE is aiming for commercial production in three years. The institute was established in 1990 by the government and leading Japanese automotive and energy firms.

The biobutanol fuel in question is obtained by converting biomass via genetically modified microorganisms. The butanol was created by cultivating a large number of these microbes in a vat and adding sugar produced by breaking down such plant fibers as grass and tree cuttings, wood and rice straw.

Light oil is generally used in diesel fuel. But in testing commissioned by RITE, Honda Motor Co. (7267.TO) subsidiary Honda R&D Co. confirmed negligible effects on vehicle performance when biobutanol was mixed with light oil:

RITE sees the biofuel as key to cutting greenhouse gases emitted from diesel vehicles. Once mass production begins, the fuel is seen costing almost the same to produce as bioethanol for gasoline-powered cars.

Demand for biofuels made from plants is expected to grow because they help curb carbon dioxide emissions. But to date, first-generation biodiesel fuels have been made from food-grade vegetable oils.

Large industrial and research organisations have been working to develop technologies for the conversion of cellulosic biomass. Players working on butanol are, besides RITE, BP Plc (BP) of the UK, DuPont Co. of the US (earlier post). RITE has already applied for an international patent on the technology.

Earlier, RITE and Honda joined efforts to develop cellulosic biomass.
