Biopower technologies convert renewable biomass fuels into heat and electricity using processes similar to those used with fossil fuels. Most electricity generated from biomass is produced by direct combustion. Biomass is burned in a boiler to produce high-pressure steam.
This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity. Biomass can also serve as substitute for a portion of coal in an existing power plant furnace in a process called co-firing combusting two different types of materials at the same time.
So scientists and startups are exploring other materials that have the potential to serve as fuel without the accompanying concerns about food supply and environmental impact. Cellulosic ethanol , for example, uses corn stover, wood waste, or other plant material that would not be used otherwise.
Other potential biofuel feedstocks include grasses , algae , animal waste , cooking grease , and wastewater sludge , but research continues to find the most efficient and cost-effective ways to transform them into usable fuel.

The properties of standardized biogenic solid fuels are comprehensively regulated in the European ISO standard and in many places in Europe are supplemented or implemented by national or international certification programs, such as ENplus and DINplus for wood pellets.
Some Petronord Group retail companies offer biofuels such as pellets in addition to petroleum products. Status: December All information subject to change.
