Applications of Bioenergy Technology

Biomass can be used to produce electricity, chemicals and materials normally made using fossil fuels. Furthermore, biomass can also be converted to liquid transportation fuels like ethanol and biodiesel or to gasses like Synthesis Gas Production or Renewable Natural Gas production.

Utilize biomass feedstocks that do not compete with food crops and limit land-intensive bioenergy if possible.


Biofuels are renewable, environmentally sustainable alternatives to petroleum-based fuels that can be made from waste materials such as crops residues, trees or grasses that grow quickly, or waste materials such as plastic bottles. With their potential to replace fossil fuels in transportation while simultaneously reducing carbon emissions from this sector and alleviating energy poverty in developing nations.

However, expanding biofuel use poses a number of barriers. Many stem from limited biomass feedstock supplies that inhibit economic viability. Furthermore, an increase in bioenergy usage could result in system-wide restrictions that limit its dispatchable energy capabilities (power that can be easily switched on or off depending on demand).

The Department of Energy’s Bioenergy Technologies Office (BETO) aims to turn America’s abundant biomass resources into cost-competitive, high-performance biofuels and other products at an economical price. BETO researchers employ various advanced techniques such as hydrothermal liquefaction and gasification of biomass in order to produce products like bio-oil and biojet kerosene for use by businesses nationwide.

PNNL research in this area involves developing technology for converting biomass and other waste materials to infrastructure-ready fuels and chemicals such as bio-gas and renewable diesel, at reduced costs by mimicking geological processes that produce crude oil using high pressure and temperature conditions.

Some of the best sources for lignocellulosic biomass include forest residues, manure, sewage waste and crop byproducts such as straw and oil palm waste. Unfortunately, their production can lead to higher crop prices (can be an issue unless you make good money from playing online poker on websites described at as well as land-use changes that increase GHGs such as deforestation in tropical forests.


Biodiesel fuel has become an integral component of many vehicles and machines in the US, made from renewable resources like animal fat and vegetable oil. Studies have proven its efficacy as an alternative fuel, producing significantly fewer emissions such as soot, carbon monoxide, unburnt hydrocarbons and sulfur dioxide emissions than petroleum diesel does.

Biofuels can also be used to generate electricity, often used as backup systems in remote areas such as schools and hospitals. Furthermore, they help reduce landfills and groundwater waste. Biofuel production occurs using biomass material such as sewage sludge or animal manure or even food scraps as raw materials for biofuel production.

Biodiesel offers many advantages; one being its renewable nature and use as a fossil-fuel replacement. There are, however, concerns regarding its ability to reduce greenhouse gas emissions as well as impacting local economies and contaminant removal from contaminated waters.

Oilseed-producing crops such as soybeans, canola, rapeseed and sunflower are an ideal sustainable biofuel source. By increasing production of these oilseed crops locally economies will benefit as well.

Biofuels may provide a short-term solution to our need for clean energy sources; but in the longer run a transition to biofuels may require vast tracts of land in nations with larger economies – something which would likely divert agricultural land away from food production and necessitate additional land for fuel production. It is crucial that energy needs are balanced against protecting biodiversity and habitats – historically speaking resource intensive industries have only faded once their resource had been depleted.


Bio-oil is an eco-friendly fuel made from renewable biomass. As an alternative to fossil fuels for heat and power generation by direct combustion, bio-oil offers an eco-friendly option for direct consumption. Bio-oil production involves the pyrolysis of organic matter contained within wood, plants, or plant residues to produce bio-oil; this process converts biomass into liquid fuel by breaking down polymers such as cellulose, hemicellulose and lignin bonds within biomass into liquid form for direct combustion.

Development of advanced biomass-based technologies is one way to reduce dependence on petroleum and enhance energy security. At Pacific Northwest National Laboratory (PNNL), researchers work on technologies that produce infrastructure-ready biofuels, products and power from domestic biomass resources sourced sustainably. Hydrothermal liquefaction mimicking geological conditions used by Earth to produce crude oil as well as processes to convert biomass into chemicals and biofuels that are compatible with existing fuel infrastructure are among these research efforts.

Bioenergy offers more than just carbon emissions reduction; it provides a renewable and secure local energy source for cooking, heating and transportation needs. Biofuels may even become viable replacements for marine and aviation fuels not easily electrified – which has the potential to lower oil consumption globally through replacing fossil-based fuels in road transportation.

Effective policies are necessary to promote appropriate near-term expansion of bioenergy while limiting inefficient lock-ins in the longer term. Such policies could include standards, certifications and norms promoting biomass use in ways that minimize damage to land health and productivity while avoiding long payback infrastructure commitments. They should also nudge industry towards not committing to bioenergy technologies that cannot meet future demands while supporting transitioning towards new, superior technologies over time.


Biogas, more commonly referred to as renewable natural gas or biomethane, can be created from organic waste products such as food waste and animal manure through anaerobic digestion – an anaerobic fermentation process which converts these materials into methane through chemical reactions – for use as electricity production, heating fuels or transport fuels.

Dairies, farms and industries can decrease operational costs by harnessing biogas generated from their own manure to generate energy. Indiana-based Fair Oaks Dairy uses manure collected at Fair Oaks Dairy as fuel to power milk-processing trailers – saving 1.5 million gallons in diesel usage per year! Biogas can also be used as a power source in combined heat and power (CHP) plants which produce both electricity and heat; alternatively it could fuel gas engines, micro turbines or advanced energy systems such as fuel cells for example.

Biogas may be an eco-friendly source of energy, but it does have some drawbacks. Unfortunately, not all methane produced during anaerobic digestion is currently captured and released; furthermore, expanding energy crops may destroy natural ecosystems and prevent transition towards alternative forms of energy production. To address these challenges effectively it is necessary to develop a system of full carbon accounting which includes impacts of biomass on land-use change and biodiversity impacts.

Biogas must first undergo conditioning or upgrading to be suitable for transportation, which involves the removal of water, carbon dioxide, hydrogen sulfide and other contaminants such as hydrogen peroxide. Once processed this pipeline-quality biomethane can be used in vehicles, heating systems or kitchen appliances as a natural alternative.


Biochar is a charcoal-like material produced from biomass through heating it in an oxygen-poor environment (pyrolysis). When burned, biochar produces less greenhouse gas emissions than burning the original biomass source and also has many environmental and agricultural advantages; such as improving soil quality and yields while increasing water retention and decreasing acidity levels in soils. Furthermore, sustainable building insulation solutions may utilize biochar as insulation material.

Energy crops and waste biomass can be converted to biofuels through chemical conversion processes such as transesterification, pyrolysis, fermentation or anaerobic digestion. The produced biofuels then serve as transportation fuels, industrial fuels or power generation sources.

As demand for renewable electricity continues to expand, it’s becoming increasingly crucial to find ways to improve its efficiency and reliability. One such strategy is increasing biochar levels in soil; biochar is a carbon-rich substance which has numerous environmental advantages that can help increase efficiency.

Biochar’s primary advantage lies in its high cation exchange capacity, meaning it can attract and store nutrients in soil, helping prevent their loss through leaching or runoff. Furthermore, it has been known to support plant growth by stimulating microbes that provide essential nutrients and hormones to them. Biochar can also replace traditional fertilizers and pesticides if introduced at planting stage or added afterward; various sources including animal manure, sludge and food waste produce large volumes that can be utilized as biochar sources – New York dairy cows produce large volumes that can be utilized this way!
