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 (or has been a member of consortia that have received) multiple multimillion-dollar grants from the United States Department of Energy and United States Department of Agriculture.
KDF is located on a 2.5-hectare (6.2-acre) parcel of land leased from the Natural Energy Laboratory of Hawaii Authority (NELHA), which is located on the west shore of the island of Hawaii. NELHA pipes in a constant supply of fresh ocean water. NELHA was originally built to support a DOE project for ocean thermal energy conversion, and it continues to employ the project's seawater supply pipes to support a variety of research projects and commercial enterprises, including facilities that currently grow and harvest microalgae for pharmaceuticals and nutritional supplements. Cellana's facility grows only non-genetically modified, marine microalgae species using proprietary technology.
Cellana, Inc. was founded in 2004 as "HR BioPetroleum, Inc." and changed its name to Cellana, Inc. in May 2011. On January 31, 2011, Cellana LLC, a joint venture company formed by Royal Dutch Shell and HR BioPetroleum in 2007, became a wholly owned subsidiary of HR BioPetroleum, Inc./Cellana, Inc. Shell had previously announced on December 11, 2007, that it entered into a joint venture with HR BioPetroleum to, among other things, build and operate a demonstration facility in Hawaii for growing algae as a source of biofuels. [2] This 2.5-hectare facility, known as the Kona Demonstration Facility (KDF), was completed and commissioned in 2009.
The original goal of the facility was to cultivate algae in photobioreactors and open raceway ponds filled with seawater using a proprietary process, then harvest the algae and extract oil for conversion into fuels such as biodiesel and utilize the residual high protein algae meal for additional co-products.
In 2018, Cellana and POS Bio-Sciences announced the signing of a letter of intent for the joint development and commercialization of high-value EPA Omega-3 oils from Cellana's algae biomass. [3] In December 2016, the United States Department of Energy published a funding opportunity announcement in which Cellana's lead commercial algae strains KA32 and CO46, and the biomass yields demonstrated from these strains as part of the DOE-funded Algae Testbed Public-Private Partnership (ATP3), were designated as DOE's "State of Technology" for the photosynthetic algae sector in the United States. [4] In 2017, Cellana and Living Ink Technologies announced the signing of a letter of intent for the joint development and commercialization of inks containing Cellana's renewable algae biomass. [5] In 2013, Cellana and Neste Oil, the world's largest refiner of renewable diesel, announced the signing of a multi-year, commercial-scale off-take agreement for algae-based biocrude oil. [6]
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.
Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few micrometers (μm) to a few hundred micrometers. Unlike higher plants, microalgae do not have roots, stems, or leaves. They are specially adapted to an environment dominated by viscous forces.
Algaculture is a form of aquaculture involving the farming of species of algae.
The Aquatic Species Program was a research program in the United States launched in 1978 by President Jimmy Carter and was funded by the United States Department of Energy, which over the course of nearly two decades looked into the production of energy using algae. Initially, the funding of the Aquatic Species Program was to develop renewable fuel for transportation. Later, the program focused on producing bio-diesel from algae. The research program was discontinued in 1996. The research staff compiled their work and conclusions into a 1998 report.
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.
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.
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.
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.
TerraVia Holdings, Inc. was a publicly held biotechnology company in the United States. TerraVia used proprietary technology to transform a range of low-cost plant-based sugars into high-value oils and whole algae ingredients. TerraVia supplied a variety of sustainable algae-based food ingredients to a number of brands, which included Hormel Food Corporation, Utz Quality Foods Inc and enjoy Life Foods. TerraVia also sold its own culinary algae oil under the Thrive Algae Oil brand.
Sapphire Energy was a San Diego-based American energy company that aimed to produce crude oil with algae.
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.
Algenol, founded in 2009, headquartered in Fort Myers, Florida, Algenol is an industrial biotechnology company that is commercializing patented algae technology for production of ethanol and other fuels. The technology enables production four of the most important fuels using a proprietary process involving algae, sunlight, carbon dioxide and salt water.
Algae fuel in the United States, as with other countries, is under study as a source of biofuel.
Wageningen UR has constructed AlgaePARC at the Wageningen Campus. The goal of AlgaePARC is to fill the gap between fundamental research on algae and full-scale algae production facilities. This will be done by setting up flexible pilot scale facilities to perform applied research and obtain direct practical experience. It is a joined initiative of BioProcess Engineering and Food & Biobased Research of the Wageningen University.
Energy in the U.S. state of Hawaii is produced from a mixture of fossil fuel and renewable resources. Producing energy is complicated by the state's isolated location and lack of fossil fuel resources. The state relies heavily on imports of petroleum. Hawaii has the highest share of petroleum use in the United States, with about 62% of electricity coming from oil in 2017. As of 2021 renewable energy made up 34.5%.
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.
