To make sourcez into liquid Sports drinks for hydration gaseous fuels, biofuels must be converted from their original form. The most basic way to do this is through fermentation of crops that are high in sugar starch or fat into ethanol, which can be mixed directly with gasoline to power cars.

In the Northwest, oilseed crops like canola or sunflowers are used to make biofuels. For a more advanced process that requires breaking down the cell walls of plants into their most basic chemical form, energy producers use a two-step process: deconstruction followed by synthesis and upgrading.

The first step, deconstruction, breaks the biomass down into its most simple components and can happen at either low or high temperatures. High temperature deconstruction includes:.

Biomass Energy Basics | NREL Biochar Biochar, produced during pyrolysis, is valuable in agricultural and environmental use. In other words, biofuel is sustainable. When fossil fuels are extracted and burned for energy, their sequestered carbon is released into the atmosphere. Hydrocarbons can also be produced from biomass sources through a variety of biological and thermochemical processes. There are three primary routes used in this pathway:. User Permissions.

Pyrolysis oil, sometimes called bio-oil or biocrude, is a type of tar. It can be combusted to generate electricity and is also used as a component in other fuels and plastics. Scientists and engineers are studying pyrolysis oil as a possible alternative to petroleum.

Syngas can be converted into fuel such as synthetic natural gas. It can also be converted into methane and used as a replacement for natural gas. Biochar is a type of charcoal. Biochar is a carbon-rich solid that is particularly useful in agriculture. Biochar enriches soil and prevents it from leaching pesticides and other nutrients into runoff.

Biochar is also an excellent carbon sink. Carbon sinks are reservoirs for carbon-containing chemicals, including greenhouse gases.

Gasification Biomass can also be directly converted to energy through gasification. During the gasification process, a biomass feedstock usually MSW is heated to more than ° C 1,° F with a controlled amount of oxygen.

The molecules break down, and produce syngas and slag. Syngas is a combination of hydrogen and carbon monoxide. During gasification, syngas is cleaned of sulfur, particulates, mercury, and other pollutants. The clean syngas can be combusted for heat or electricity, or processed into transportation biofuels, chemicals, and fertilizers.

Slag forms as a glassy, molten liquid. It can be used to make shingles, cement, or asphalt. Industrial gasification plants are being built all over the world. Asia and Australia are constructing and operating the most plants, although one of the largest gasification plants in the world is currently under construction in Stockton-on-Tees, England.

This plant will eventually be able to convert more than , tons of MSW into enough energy to power 50, homes.

Anaerobic Decomposition Anaerobic decomposition is the process where microorganisms , usually bacteria , break down material in the absence of oxygen.

Anaerobic decomposition is an important process in landfills , where biomass is crushed and compressed, creating an anaerobic or oxygen-poor environment.

In an anaerobic environment, biomass decays and produces methane, which is a valuable energy source. This methane can replace fossil fuels.

In addition to landfills, anaerobic decomposition can also be implemented on ranches and livestock farms. Manure and other animal waste can be converted to sustainably meet the energy needs of the farm.

Biofuel Biomass is the only renewable energy source that can be converted into liquid biofuels such as ethanol and biodiesel. Biofuel is used to power vehicles, and is being produced by gasification in countries such as Sweden, Austria, and the United States.

Ethanol is made by fermenting biomass that is high in carbohydrates, such as sugarcane, wheat, or corn. Biodiesel is made from combining ethanol with animal fat, recycled cooking fat, or vegetable oil.

Biofuels do not operate as efficiently as gasoline. However, they can be blended with gasoline to efficiently power vehicles and machinery, and do not release the emissions associated with fossil fuels. Ethanol requires acres of farmland to grow biocrops usually corn.

About 1, liters gallons of ethanol is produced by an acre of corn. But this acreage is then unavailable for growing crops for food or other uses. Growing enough corn for ethanol also creates a strain on the environment because of the lack of variation in planting, and the high use of pesticides.

Ethanol has become a popular substitute for wood in residential fireplaces. When it is burned, it gives off heat in the form of flames, and water vapor instead of smoke. Biochar Biochar, produced during pyrolysis, is valuable in agricultural and environmental use.

When biomass rots or burns naturally or by human activity , it releases high amounts of methane and carbon dioxide into the atmosphere.

However, when biomass is charred, it sequesters , or stores, its carbon content. When biochar is added back to the soil, it can continue to absorb carbon and form large underground stores of sequestered carbon—carbon sinks—that can lead to negative carbon emissions and healthier soil.

Biochar also helps enrich the soil. It is porous. When added back to the soil, biochar absorbs and retains water and nutrients. Slash-and-char agriculture replaces slash-and-burn , which temporarily increases the soil nutrients but causes it to lose 97 percent of its carbon content.

During slash-and-char, the charred plants biochar are returned to the soil, and the soil retains 50 percent of its carbon. 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 United States, paper mills use nearly all their black liquor to run their mills, and the forest industry is one of the most energy-efficient in the nation as a result.

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. state of California, for example, uses hydrogen fuel cells to provide electricity and hot water to its administration building.

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 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 extracted 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 reabsorb 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 reabsorb 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 pollutants 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. state of Maine to grow enough algae to replace all petroleum-fueled energy needs in the United States.

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 lipids 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.

Background

Even the fumes from landfills which contain methane, the main component in natural gas can be used as a biomass energy source. Biomass can be used for fuels , power production, and products that would otherwise be made from fossil fuels.

NREL's vision is to develop technology for biorefineries that will convert biomass into a range of valuable fuels, chemicals, materials, and products—much like oil refineries and petrochemical plants do.

Biofuels are transportation fuels, such as ethanol and biodiesel, created by converting biomass into liquid fuels to meet transportation needs. Learn more about biofuels. In addition to electricity and fuels, biomass can also be converted into chemicals for making plastics and other products that typically are made from petroleum.

The use of biomass energy has the potential to greatly reduce greenhouse gas emissions. Burning biomass releases about the same amount of carbon dioxide as burning fossil fuels. However, fossil fuels release carbon dioxide captured by photosynthesis millions of years ago—an essentially "new" greenhouse gas.

Biomass, on the other hand, releases carbon dioxide that is largely balanced by the carbon dioxide captured in its own growth depending how much energy was used to grow, harvest, and process the fuel.

However, studies have found that clearing forests to grow biomass results in a carbon penalty that takes decades to recoup, so it is best if biomass is grown on previously cleared land, such as under-utilized farmland.

The use of biomass can reduce dependence on foreign oil because biofuels are the only renewable liquid transportation fuels available.

Biomass energy supports U. agricultural and forest-product industries. The main biomass feedstocks for power are paper mill residue, lumber mill scrap, and municipal waste.

How biomass is processed depends on the type of biomass e. The three main processes by which energy can be obtained from biomass are:.

Biofuel can be produced from plants or Pllant-based agricultural, domestic or industrial biowaste. Biofuels are mostly used for transportation, but can also be used for heating and electricity. In general, biofuels emit fewer greenhouse gas emissions when burned in an engine and are generally considered carbon-neutral fuels as the carbon emitted has been captured from the atmosphere by the crops used in production. The two most common types of biofuel are bioethanol and biodiesel. Brazil is the largest producer of bioethanol, while the EU is the largest producer of biodiesel.
