ENERGY-BRAZIL: Elephant Grass for Biomass
By Mario Osava
RIO DE JANEIRO, Oct 10 (IPS) - Sugarcane is gradually being edged out of pole position for biofuel efficiency, as studies by the Agrobiology Centre at the state Brazilian Agricultural Research Corporation (Embrapa) are finding that elephant grass has even greater potential.
Its dry biomass, burned in ovens, can generate 25 times as much energy as the amount of fossil fuel used to produce it, while sugarcane converted into ethanol only produces nine times as much.
But these two energy balance leaders face different challenges and must travel down different paths before they can compete, for instance, as fuels for electricity generation.
Elephant grass (Pennisetum purpureum) has only recently captured the interest...(complete article here).
All bio fuels ultimately run into the same problems. Fuel vs. food, water, land, etc. We need to be exploring new energy technologies.
