At thecurrent rate of consumption, fossil oil reserves will be depleted in less than50 years. Many researchers around theworld have thought for years about what to do "after oil" and havetried to find alternatives that are greener, less polluting during extraction,and more sustainable. Agro-fuels are very controversial in terms of ecologicalimpact, especially their effect on farm commodity prices. After the first 2generations of biofuels, for many years, research has turned towards "algo-fuels,”the 3rd generation in biofuels, which naturally reproduces the creation offossil fuel in a few days, thanks to the photosynthesis of microalgae. Theconcern from the first tests was that the process would be just too expensive.Bio Fuel System, a Spanish company, founded after five years of research withthe Universities of Alicante and Valencia, has developed the first “acceleratedenergy conversion process."
BIO FUEL SYSTEMS transform the CO ² from industries into oil, finding inspiration from nature.
Energy / Greenhouse Gases (GHG)
- Find a lasting solution for oil substitution which can be developed at alarge scale.
- Absorb the C02 emitted by industries (over 30% of CO2 emissions) to limit globalwarming and use this waste as new raw material.
The production process of BioFuel Systems’s "blue oil":
- Selection of strains of cyanobacteria and phytoplankton in the vicinity ofproduction sites (no negative effect on biodiversity).
- Implementation as close as possible to plants emitting large amounts of CO2 fromvertical tubes of 8m high where micro-algae multiplies due to CO2 andphotosynthesis. Each day the amount doubles. Every day, half of the tubes are removed and centrifuged. The next day thetubes become full again.
- The centrifuged paste contains 2-3% of nutrients (omega 3 or 6) and 97%biomass, which is transformed into oil.
- The sale of nutrients allows for profitable operations (1 ton of omega-3 isvalued at 56,000 Euros on the market)
- 1 hectare of farmland can absorb 12,000 tons of C02 per year and providesongoing annual production of 5,500 barrels of oil.
- 2.2 tons of CO2 are required to produce a barrel of “blue oil” of which 1.2tons of C02 is emitted indirectly (direct emissions are put back into theproduction process) => 940 kg of C02 are thus neutralized in each barrelproduced.
The first pilot production farm (40 ha to run) just opened in January 2011 inAlicante, alongside the Cemex cement plant, third in the world for cementproduction.
CONTRIBUTION TO COMPANY PERFORMANCE
- 2 other sites are already under construction in Madeira and Venice. 6-8production units are planned over the next 3 years. 50 plants planned by 2020.
- The facilities are amortized over 4 years.
- Cemex and BFS obtained the "Sustainable Innovation Award" inNovember 2009 for the quality of their partnership and the interests oftechnological breakthrough.
- The most water-efficient fuel: 0.1 L of water needed for 1L of oil vs1000L for 1L of bioethanol
- No pressure on farmland or on food commodities
- Oil without sulfur or heavy metals thus muchcleaner combustion and refining.
