Bioliquids are liquid fuels made from biomass for energy purposes other than transport (i.e. heating and electricity).
Bioliquids are usually made from virgin or used vegetable and seed oils, like palm or soya oil. 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. This steam can then be used to drive a turbine to generate electricity.
Rudolf Diesel's first public exhibition of the internal combustion engine, that was to later bear his name, ran on peanut oil.
Bioliquids have been used for many years to provide heat for homes on a small scale but now big energy providers are looking at their use on a larger scale.
A controversial plant in Bristol (UK) was recently given the go ahead despite receiving several hundred complaints. The plant will be built and operated by W4B and provide enough power for 25,000 homes.
