New Efficient
Bio-Fuel Manufacturing Method

Latest modification to bio-fuel production methods can produce more of the green fuel using less of biomass.

Researchers from the School of Chemical Engineering at Purdue University have designed a manufacturing process whereby hydrogen is added during a process called gasification. This method limits the carbon dioxide output and make the process more efficient. It has the potential to produce three times the volume of biofuel from the same quantity of biomass. With this process it is possibe to provide enough bio-fuel to supply the entire US transportation sector according to the inventors.

Biofuels can be made from plants such as willow mass, forrest thinnings, rape seed cake and other material derived from plants which could include manure, kitchen waste and human sewage. The processes currently in use are not considered efficient enough because they waste too much of the carbon dioxide produced from the biomass. Up to two thirds of the CO2 from the required biomass is released into the atmosphere in this process.

In the new process, the CO2 would be recycled into usable fuel by forcing it to react with hydrogen. The process is called H2CAR.

The hydrogen required by the process can be got from solar power or wind power.

But you know what? - Whats the point in mentioning this in Ireland!!!
