A major technical obstacle in entrained-flow gasification of biomass concerns the size reduction and the subsequent pneumatic transport of the biomass powder. The fibrous structure of fresh biomass makes it very difficult and costly to reduce its particle size down to below 500 microns.

The current challenge

The world faces a “perfect storm” of food, water and energy shortages. Food stocks are the lowest they’ve been in 50 years. John Beddington, chief scientific advisor to the UK Government, has stated that 50% more food, 50% more energy and 30% more water will be needed by 2030 to supply a growing population. Even in developed nations like Britain and Australia, rising environmental pressure on crops would drive up import prices. Higher temperatures and less water brought about by climate change is expected to make some crop growing area difficult to manage, particularly in areas which are already experiencing drier than normal conditions. However, the precise impacts of climate change are difficult to predict accurately.
