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

* Price of fuel is very variable, due to competitiveness of feedstock for other uses (e.g. soap) * Supply chain is still very new * Governments, such as the EU, remained undecided on bioliquids
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
Palm most commonly refers to:
* Palm of the hand, the central region of the front of the hand
* Palm plants, of family Arecaceae

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.

(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.
Advantages
Bioliquids have several key advantages over other sources of renewable energy: * Bioliquids have a high energy density * The technology is well established, having been used for many years * Can be used on demand, reacting quickly to changes in demand for power * Can help reduce dependency on foreign oil. * Reduces the green house gas emissions.Disadvantages
Many of the same problems that affect biofuels also affect bioliquids and there are various social, economic, environmental and technical issues, which have been discussed in the popular media and scientific journals. These include: the effect of moderatingoil prices
