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 may refer to :* Palm, the central region of the front of the hand, see Hand#Human anatomy or metacarpus.-People:* August Palm , Swedish socialist activist* Conny Palm, , Swedish electrical engineer and statistician...
Soya can mean:* Soya bean* Sōya District, Hokkaidō* Sōya Subprefecture, Hokkaidō* Soya3D, a high-level three-dimensional rendering engine for the Python programming language* Soya sauce, a fermented sauce made from soybeans, roasted grain, water and salt....
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 Christian Karl Diesel was a German inventor and mechanical engineer, famous for the invention of the diesel engine.-Early life:Diesel was born in Paris, France in 1858 the second of three children of Theodor and Elise Diesel. His parents were Bavarian immigrants living in Paris. Theodor...

The peanut, or groundnut , is a species in the legume or "bean" family , so it is not a nut. The peanut was probably first cultivated in the valleys of Peru. It is an annual herbaceous plant growing tall...
Bioliquid production and useBioliquids 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
Bristol is a city, unitary authority area and ceremonial county in South West England, with an estimated population of 433,100 for the unitary authority in 2009, and a surrounding Larger Urban Zone with an estimated 1,070,000 residents in 2007...
(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.
AdvantagesBioliquids 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
DisadvantagesMany 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 moderating oil prices, the "food vs fuel
Food vs fuel
Food vs. fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. The "food vs. fuel" or "food or fuel" debate is international in scope, with good and valid arguments on all sides of this issue...

Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is a measure of the health of ecosystems. Biodiversity is in part a function of climate. In terrestrial habitats, tropical regions are typically rich whereas polar regions...

, as well as energy balance and efficiency.
Bioliquids also have several key problems compared to other sources of renewable energy:
- 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
- Bioheat, a biofuel blended with heating oilHeating oilHeating oil, or oil heat, is a low viscosity, flammable liquid petroleum product used as a fuel for furnaces or boilers in buildings. Home heating oil is often abbreviated as HHO...
