Biomass energy can be used in different ways. This article explains its four different categories: the biopower, biofuels, bioproducts and space heating as well as cooling.
First is the biopower. Hydropower is perhaps the only renewable source of energy which is used more than biopower. Biomass is actually produced by direct combustion with the help of conventional boilers that will designed to burn waste wood stuff. The steam which is being produced by that combustion, leads the turbine to spins and activates the generator that produces the electricity.
Second is the biofuels. Ethanol and biodiesel are the two mostly available biofuels. Ethanol is generally prepared from the starch which is present in the corn grain which are then added into petroleum-based fuels for the reduction of toxic air emissions as well as increasing the percentage of octane. This is available as a commercial fuel and you can find it with the name of E-85. This fuel type consists of nearly 83% of ethyl alcohol during summer season and near about 70% during the winters.
On the other side, biodiesel, which is also a nice renewable alternative is made mostly from soybean oil. Although it is not quite popular as compared to ethanol yet it has noteworthy benefits to air quality. The biodiesel when mixed with petroleum deisel in 20%, it is then referred to as B-20. With the same process of creating biofuels, it can also be used to create antifreeze, glues, plastics, artificial sweeteners as well as toothpaste gels. When biomass turned to gas prior to the combustion, it removes those toxic materials.
Third is the bioproducts. Created generally from the fossil fuels, bioproducts require a small amount of energy for production as compared to petroleum based products. Excess of the two gases will be produced in case of the presence of oxygen in biomass heating. The process is known as biosynthesis. This is also useful in creating photographic films. Moreover, when biomass will be heated in the absence of oxygen, we get the pyrolysis oil.
Lastly is the space heating and cooling which accounts for over 56% of the energy which renders it the largest energy expense for majority of homes. Thus, it is still crucial to research on the most effective ways in utilizing renewable energy...
