Bioliquids

Bioliquids are liquid fuels made from biomass for energy purposes other than transport (i.e. heating and electricity).

These oils are burned in a power station to create heat, which can then be used to warm homes or boil water to make steam.

Rudolf Diesel's first public exhibition of the internal combustion engine, that was to later bear his name, ran on peanut oil.

A controversial plant in Bristol (UK) was recently given the go ahead despite receiving several hundred complaints.

These include: the effect of moderating oil prices, the "food vs fuel" debate, poverty reduction potential, carbon emissions levels, sustainable biofuel production, deforestation and soil erosion, loss of biodiversity, impact on water resources, as well as energy balance and efficiency.
