Camelina is a genus within the flowering plant family Brassicaceae. The Camelina species, commonly known as false flax, are native to Mediterranean regions of Europe and Asia. Most species of this genus have been little studied, with the exception of Camelina sativa , historically cultivated as an oil plant. Heinrich Johann Nepomuk von Crantz was the first botanist to use the genus Camelina in his classification works in 1762. As a way to reduce fossil fuel emissions, the US Navy tested a 50-50 mix of jet aviation fuel and biofuel derived from camelina seeds in 2010. [1] A study published in December 2016 explained that the current low price of conventional kerosene-based jet fuel makes it cost-prohibitive for commercial airlines to use camelina-based jet fuel. The study said substantial government intervention would be one way to create a market for camelina, by combining 9 percent government subsidy on camelina crop production, with 9 percent tax on conventional fuel. [2]
The name Camelina comes from the Greek for "ground" and "flax", alluding to its being a weed which suppresses the vigour of flax crops. [3]
Camelina plants are annual or biennial herbs. Their leaves are simple, lanceolate to narrowly elliptic. The flowers are hermaphroditic actinomorphic, grouped in racemes, and yellowish colored. The seeds are formed in dehiscent siliques. [4]
The first full genome sequence for Camelina sativa was released on August 1, 2013, by a Canadian research team. The genome sequence and its annotation are available in a genome viewer format and enabled for sequence searching and alignment. [5] Technical details of Camelina's genome sequence were published on April 23, 2014 in the academic journal Nature Communications . [6]
Rothamsted Institute in the UK developed genetically modified Camelina sativa plants that accumulate in their seeds high levels of the longer chain omega-3 oils EPA and DHA, commonly found in fish oils. These plants could provide terrestrial sustainable sources of longer chain omega-3 fatty acids and have benefits for human health and the environment. [7] Field trials were underway in 2016. [8]
Four common species are presented below. However, at least two databanks indicate more species may exist. [9]
Biodiesel made from camelina has a variety of benefits. First, traditional petroleum or diesel fuel is not renewable resources, the production of these resources is finite. Camelina biodiesel, however, is a renewable resource. Camelina based aviation fuel could save 84% of carbon emissions. [11] Camelina biodiesel can be produced in large quantities as feedstocks are enough. Moreover, camelina biodiesel can reduce a country's dependence on fossil resources, which can ensure a country's energy security. In addition, camelina biodiesel is an environmentally friendly fuel, and it is biodegradable. [12] The greenhouse gas emission of camelina biodiesel produced by no-till farming is lower than that of traditional methods. [13]
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. Biofuels are mostly used for transportation, but can also be used for heating and electricity. Biofuels are regarded as a renewable energy source. However, the use of biofuel has been controversial because of the several disadvantages associated with the use of it. These include for example : the "food vs fuel" debate, biofuel production methods being sustainable or not, leading to deforestation and loss of biodiversity or not.
Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters. It is typically made by chemically reacting lipids such as animal fat (tallow), soybean oil, or some other vegetable oil with an alcohol, producing a methyl, ethyl or propyl ester by the process of transesterification.
Camelina sativa is a flowering plant in the family Brassicaceae usually known as camelina, gold-of-pleasure, or false flax, but also occasionally as wild flax, linseed dodder, German sesame, or Siberian oilseed. It is native to Europe and areas of Central Asia, but cultivated as an oilseed crop mainly in Europe and in North America. It is not related to true flax, in the family Linaceae.

Whether as an admixture or in its pure form, Neste MY Renewable Diesel is able to supplement or partially replace diesel fuel without problems. Neste MY Renewable Diesel guarantees that every gallon sold meets ASTM D975 and EN 15940 specifications in compliance with OEM standards.
Energy crops are low-cost and low-maintenance crops grown solely for renewable bioenergy production. The crops are processed into solid, liquid or gaseous fuels, such as pellets, bioethanol or biogas. The fuels are burned to generate electrical power or heat.
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.
Thlaspi arvense, known by the common name field pennycress, is a flowering plant in the cabbage family Brassicaceae. It is native to Eurasia, and is a common weed throughout much of North America and its home.
Biofuel is fuel that is produced from organic matter (biomass), including plant materials and animal waste. It is considered a renewable source of energy that can assist in reducing carbon emissions. The two main types of biofuel currently being produced in Australia are biodiesel and bioethanol, used as replacements for diesel and petrol (gasoline) respectively. As of 2017 Australia is a relatively small producer of biofuels, accounting for 0.2% of world bioethanol production and 0.1% of world biodiesel production.
Vegetable oils are increasingly used as a substitute for fossil fuels. Vegetable oils are the basis of biodiesel, which can be used like conventional diesel. Some vegetable oil blends are used in unmodified vehicles, but straight vegetable oil often needs specially prepared vehicles which have a method of heating the oil to reduce its viscosity and surface tension, sometimes specially made injector nozzles, increased injection pressure and stronger glow-plugs, in addition to fuel pre-heating is used. Another alternative is vegetable oil refining.
Jatropha curcas is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to the American tropics, most likely Mexico and Central America. It is originally native to the tropical areas of the Americas from Mexico to Argentina, and has been spread throughout the world in tropical and subtropical regions around the world, becoming naturalized or invasive in many areas. The specific epithet, "curcas", was first used by Portuguese doc Garcia de Orta more than 400 years ago. Common names in English include physic nut, Barbados nut, poison nut, bubble bush or purging nut. In parts of Africa and areas in Asia such as India it is often known as "castor oil plant" or "hedge castor oil plant", but it is not the same as the usual castor oil plant, Ricinus communis.
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.
Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of the food supply. The biofuel and food price debate involves wide-ranging views, and is a long-standing, controversial one in the literature. There is disagreement about the significance of the issue, what is causing it, and what can or should be done to remedy the situation. This complexity and uncertainty is due to the large number of impacts and feedback loops that can positively or negatively affect the price system. Moreover, the relative strengths of these positive and negative impacts vary in the short and long terms, and involve delayed effects. The academic side of the debate is also blurred by the use of different economic models and competing forms of statistical analysis.
Sustainable biofuel is biofuel produced in a sustainable manner. It is not based on petroleum or other fossil fuels. It includes not using plants that are used for food stuff to produce the fuel thus disrupting the world's food supply.
An aviation biofuel or bio-jet fuel or bio-aviation fuel (BAF) is a biofuel used to power aircraft and is said to be a sustainable aviation fuel (SAF). The International Air Transport Association (IATA) considers it a key element to reducing the carbon footprint within the environmental impact of aviation. Aviation biofuel could help decarbonize medium- and long-haul air travel generating most emissions, and could extend the life of older aircraft types by lowering their carbon footprint.
SG Biofuels is a privately held bioenergy crop company, which grows and researches Jatropha curcas for the production of biodiesel, bio jet fuel, and specialty chemicals.
The indirect land use change impacts of biofuels, also known as ILUC or iLUC, relates to the unintended consequence of releasing more carbon emissions due to land-use changes around the world induced by the expansion of croplands for ethanol or biodiesel production in response to the increased global demand for biofuels.
Global Clean Energy Holdings (OTC:GCEH) is a Southern California-based renewable energy company with interests in the production and commercialization of non-food-based feedstocks used for the production of biofuels, biomass, and renewable chemicals. It was founded in 2007.
Sustainable Oils is a renewable fuels company specializing in the research and production of Camelina, the only advanced biofuels feedstock with United States Department of Agriculture, Environmental Protection Agency, and Food and Drug Administration (FDA) regulatory approvals. Oil extracted from Camelina seeds can be processed into a number of renewable products including renewable jet fuel, green diesel, biodiesel, green plastics and renewable oleochemicals. The biomass that remains after oil extraction, generally referred to seedcake or meal, can be used as nutrient-rich animal feed. Camelina offers several advantages over traditional biofuel feedstocks like soy and corn, such as competitive oil yields and shorter growing seasons. Sustainable Oils has its primary operations in the state of Montana and is headquartered in Great Falls.
