What type of fuel is biomass

Check out the difference between each type of biomass fuel:. Solid biomass includes:. Biogas comes from the following:. Liquid Biofuel encompasses:. Since we can always grow trees and crops and both solid and human waste will always be produced, there is no finite amount of biomass available for us to use as energy. Even though full utilization of biomass fuels is still in its infancy, there are definitely benefits that can be seen now, as well as the many potential benefits they each may hold in the future.

The combustion of solid biomass does not increase the carbon dioxide in the global atmosphere. Instead, the user will need to put the logs in the burners by hand, which means that they are far more maintenance-heavy.

Despite their lower calorific value and the fact they are more awkward to handle, wood logs do tend to be very popular and are used across the UK to power a variety of stoves that heat individual rooms or biomass boilers that heat both the home and the water system.

The reason being is that people who use them often have a free source of these logs to fuel their systems. This low maintenance plant, in terms of nutritional needs, can be chopped or pelleted and in some cases can be used in typical wood chip or pellet boiler systems. It is fast becoming an important biomass fuel in the UK as farmers have begun planting large crops on low-grade land.

It is important to remember that the cost of a certain type of fuel will differ from one installation to another, for a number of reasons including:. Logistics — This includes distance from raw materials, delivery vehicle, frequency and volume of fuel required, discharge rates to move the fuel from the vehicle to storage.

Market — Source of fuel, contract type i. Save my name, email, and website in this browser for the next time I comment.

Biomass fuel is considered to be renewable One of the key things about biomass fuels is that they are considered sustainable and renewable. Latest Videos. Latest Posts. When added back to the soil, biochar absorbs and retains water and nutrients.

This enhances the soil and leads to significantly higher plant growth. Black Liquor When wood is processed into paper, it produces a high-energy, toxic substance called black liquor. Until the s, black liquor from paper mills was considered a waste product and dumped into nearby water sources. With the invention of the recovery boiler in the s, black liquor could be recycled and used to power the mill. In the U. More recently, Sweden has experimented in gasifying black liquor to produce syngas, which can then be used to generate electricity.

Hydrogen Fuel Cells Biomass is rich in hydrogen, which can be chemically extracted and used to generate power and to fuel vehicles. Stationary fuel cells are used to generate electricity in remote locations, such as spacecraft and wilderness areas.

Yosemite National Park in the U. Hydrogen fuel cells may hold even more potential as an alternative energy source for vehicles. The U. Department of Energy estimates that biomass has the potential to produce 40 million tons of hydrogen per year. This would be enough to fuel million vehicles. Currently, hydrogen fuel cells are used to power buses, forklifts, boats, and submarines, and are being tested on airplanes and other vehicles.

However, there is a debate as to whether this technology will become sustainable or economically possible. The energy that it takes to isolate, compress, package, and transport the hydrogen does not leave a high quantity of energy for practical use. The carbon cycle is the process by which carbon is exchanged between all layers of the Earth: atmosphere , hydrosphere , biosphere , and lithosphere.

The carbon cycle takes many forms. It is exchanged through photosynthesis, decomposition, respiration, and human activity. Carbon that is absorbed by soil as an organism decomposes, for example, may be recycled as a plant releases carbon-based nutrients into the biosphere through photosynthesis. Under the right conditions, the decomposing organism may become peat , coal, or petroleum before being extract ed through natural or human activity.

Between periods of exchange, carbon is sequestered, or stored. The carbon in fossil fuels has been sequestered for millions of years. When fossil fuels are extracted and burned for energy, their sequestered carbon is released into the atmosphere. Fossil fuels do not re-absorb carbon. In contrast to fossil fuels, biomass comes from recently living organisms.

The carbon in biomass can continue to be exchanged in the carbon cycle. In order to effectively allow Earth to continue the carbon cycle process, however, biomass materials such as plants and forests have to be sustainably farmed.

It takes decades for trees and plants such as switchgrass to re-absorb and sequester carbon. Uprooting or disturbing the soil can be extremely disruptive to the process. A steady and varied supply of trees, crops, and other plants is vital for maintaining a healthy environment. Algal Fuel Algae is a unique organism that has enormous potential as a source of biomass energy. Algae, whose most familiar form is seaweed , produces energy through photosynthesis at a much quicker rate than any other biofuel feedstock—up to 30 times faster than food crops!

Algae can be grown in ocean water, so it does not deplete freshwater resources. It also does not require soil, and therefore does not reduce arable land that could potentially grow food crops.

Although algae releases carbon dioxide when it is burned, it can be farmed and replenished as a living organism. As it is replenished, it releases oxygen, and absorbs pollutant s and carbon emissions.

Algae takes up much less space than other biofuel crops. Department of Energy estimates that it would only take approximately 38, square kilometers 15, square miles, an area less than half the size of the U. Algae contains oils that can be converted to a biofuel.

At the Aquaflow Bionomic Corporation in New Zealand, for example, algae is processed with heat and pressure. Algae is an excellent filter that absorbs carbon emissions. Bioenergy Ventures, a Scottish firm, has developed a system in which carbon emissions from a whiskey distillery are funneled to an algae pool.

The algae flourishes with the additional carbon dioxide. When the algae die after about a week they are collected, and their lipid s oils are converted into biofuel or fish food. Algae has enormous potential as an alternative energy source. However, processing it into usable forms is expensive. The cost will likely come down, but it is currently out of reach for most developing economies.

People and Biomass Advantages Biomass is a clean, renewable energy source. Its initial energy comes from the sun, and plants or algae biomass can regrow in a relatively short amount of time. Trees, crops, and municipal solid waste are consistently available and can be managed sustainably. If trees and crops are sustainably farmed, they can offset carbon emissions when they absorb carbon dioxide through respiration.

Biomass fuels provided about 4 percent of the energy used in the United States in Of this, about 46 percent was from wood and wood-derived biomass, 43 percent was from biofuels mainly ethanol , and about 11 percent was from municipal waste.

Researchers are trying to develop ways to burn more biomass and fewer fossil fuels. Using biomass for energy cuts back on waste and greenhouse gas emissions. Biomass offers other significant environmental and consumer benefits, including improving forest health, protecting air quality, and offering the most dependable renewable energy source.
