Lawrence Berkeley National Laboratory (LBNL) is a federally funded research and development center in the hills of Berkeley, California, United States. Established in 1931 by the University of California (UC), the laboratory is sponsored by the United States Department of Energy and administered by the UC system. Ernest Lawrence, who won the Nobel prize for inventing the cyclotron, founded the Lab and served as its Director until his death in 1958. Located in the hills of Berkeley, California, the lab overlooks the campus of the University of California, Berkeley.
Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels, such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial biowaste.
Cellulosic ethanol is ethanol produced from cellulose rather than from the plant's seeds or fruit. It can be produced from grasses, wood, algae, or other plants. It is generally discussed for use as a biofuel. The carbon dioxide that plants absorb as they grow offsets some of the carbon dioxide emitted when ethanol made from them is burned, so cellulosic ethanol fuel has the potential to have a lower carbon footprint than fossil fuels.
Pyrolysis oil, sometimes also known as bio-crude or bio-oil, is a synthetic fuel under investigation as substitute for petroleum. It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling. Pyrolysis oil is a kind of tar and normally contains levels of oxygen too high to be considered a pure hydrocarbon. This high oxygen content results in non-volatility, corrosiveness, immiscibility with fossil fuels, thermal instability, and a tendency to polymerize when exposed to air. As such, it is distinctly different from petroleum products. Removing oxygen from bio-oil or nitrogen from algal bio-oil is known as upgrading.
Jay D. Keasling is a professor of chemical engineering and bioengineering at the University of California, Berkeley. He is also associate laboratory director for biosciences at the Lawrence Berkeley National Laboratory and chief executive officer of the Joint BioEnergy Institute. He is considered one of the foremost authorities in synthetic biology, especially in the field of metabolic engineering.
Lignocellulose refers to plant dry matter (biomass), so called lignocellulosic biomass. It is the most abundantly available raw material on the Earth for the production of biofuels. It is composed of two kinds of carbohydrate polymers, cellulose and hemicellulose, and an aromatic-rich polymer called lignin. Any biomass rich in cellulose, hemicelluloses, and lignin are commonly referred to as lignocellulosic biomass. Each component has a distinct chemical behavior. Being a composite of three very different components makes the processing of lignocellulose challenging. The evolved resistance to degradation or even separation is referred to as recalcitrance. Overcoming this recalcitrance to produce useful, high value products requires a combination of heat, chemicals, enzymes, and microorganisms. These carbohydrate-containing polymers contain different sugar monomers and they are covalently bound to lignin.
The United States produces mainly biodiesel and ethanol fuel, which uses corn as the main feedstock. The US is the world's largest producer of ethanol, having produced nearly 16 billion gallons in 2017 alone. The United States, together with Brazil accounted for 85 percent of all ethanol production, with total world production of 27.05 billion gallons. Biodiesel is commercially available in most oilseed-producing states. As of 2005, it was somewhat more expensive than fossil diesel, though it is still commonly produced in relatively small quantities.
Renewable Fuels are fuels produced from renewable resources. Examples include: biofuels, Hydrogen fuel, and fully synthetic fuel produced from ambient carbon dioxide and water. This is in contrast to non-renewable fuels such as natural gas, LPG (propane), petroleum and other fossil fuels and nuclear energy. Renewable fuels can include fuels that are synthesized from renewable energy sources, such as wind and solar. Renewable fuels have gained in popularity due to their sustainability, low contributions to the carbon cycle, and in some cases lower amounts of greenhouse gases. The geo-political ramifications of these fuels are also of interest, particularly to industrialized economies which desire independence from Middle Eastern oil.
The Energy Biosciences Institute (EBI) is an organization dedicated to developing new sources of energy and reducing the impact of energy consumption. It was created in 2007 to apply advanced knowledge of biology to the challenges of responsible, sustainable energy production and use. Its main goal is to develop next-generation biofuels—that is, biofuels that are made from the non-edible parts of plants and reduce greenhouse gas emissions.
Acetone–butanol–ethanol (ABE) fermentation, also known as the Weizmann process, is a process that uses bacterial fermentation to produce acetone, n-butanol, and ethanol from carbohydrates such as starch and glucose. It was developed by chemist Chaim Weizmann and was the primary process used to produce acetone, which was needed to make cordite, a substance essential for the British war industry during World War I.
Second-generation biofuels, also known as advanced biofuels, are fuels that can be manufactured from various types of non-food biomass. Biomass in this context means plant materials and animal waste used especially as a source of fuel.
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
Biogasoline, or biopetrol, is a type of gasoline produced from biomass such as algae. Like traditionally produced gasoline, it is made up of hydrocarbons with 6 (hexane) to 12 (dodecane) carbon atoms per molecule and can be used in internal combustion engines. Biogasoline is chemically different from biobutanol and bioethanol, as these are alcohols, not hydrocarbons.
Cellana, Inc. is an American company which develops of algae-based bioproducts for high-value nutrition, ink, and bioenergy applications, including Omega-3 nutraceutical applications, sustainable ink, aquaculture and animal feeds, human food ingredients, pigments, specialty chemicals, and biofuels. The company, with offices in Hawaii and San Diego, has received multiple multimillion-dollar grants from the United States Department of Energy and United States Department of Agriculture.
Bioproducts or bio-based products are materials, chemicals and energy derived from renewable biological material.
Biorefining is the process of "building" multiple products from biomass as a feedstock or raw material much like a petroleum refinery that is currently in use. A biorefinery is a facility like a petroleum refinery that comprises the various process steps or unit operations and related equipment to produce various bioproducts including fuels, power, materials and chemicals from biomass. Industrial biorefineries have been identified as the most promising route to the creation of a new domestic biobased industry producing entire spectrum of bioproducts or bio-based products.
Hydrothermal liquefaction (HTL) is a thermal depolymerization process used to convert wet biomass, and other macromolecules, into crude-like oil under moderate temperature and high pressure. The crude-like oil has high energy density with a lower heating value of 33.8-36.9 MJ/kg and 5-20 wt% oxygen and renewable chemicals. The process has also been called hydrous pyrolysis.
The Great Lakes Bioenergy Research Center (GLBRC) is one of four bioenergy research centers established in 2007 by the U.S. Department of Energy. It is led by the University of Wisconsin-Madison with Michigan State University as a primary partner. The goal of GLBRC is to create biofuels and bioproducts that are economically viable and environmentally sustainable. GLBRC provides a collaborative environment in which researchers with diverse backgrounds are drawn together by their pursuit of scientific questions related to developing sustainable biofuels and bioproducts. GLBRC research focuses on engineering bioenergy crops to enhance their environmental and economic value, generating multiple products from plant biomass, and optimizing the field-to-product pipeline. Its research is integrated across many disciplines and areas of focus, coordinating efforts between academic, federal, and private sector bodies as part of the field-to-product pipeline.
