Algae Systems Testing Algae Bio-Fuel Production

Demonstration Plant to Pioneer Eco-friendly, Economical and Energy-generating Wastewater Treatment Process

DAPHNE, Ala.--Algae Systems LLC completed demonstration of a new biofuel production approach in early-August jointly with Japan's IHI Corporation. The process is based on the conversion of algae and wastewater to energy and clean water. A demonstration plant, located in Daphne Alabama, combines wastewater with algae to produce the world's first energy-generating wastewater treatment process, using carbon-negative technologies. This process will yield both bio-fuel and drinking water.

Features of the Algae Systems Process – Treating Municipal Wastewater

While algae is a component in a number of worldwide experimental production strategies, this approach will differ by using a system that can apply a variety of algae types to production, adding value by treating wastewater, and producing a drop-in fuel solution using hydrothermal liquefaction to produce fuels that do not need to be blended.

Systems Approach Promotes Algae Growth

The production is being conducted by Algae Systems, LLC., which has operations based in Daphne, Alabama. Algae Systems is a group company of IHI Corporation based on a joint venture partnership with Algae Systems' founders. The Daphne approach takes local strains of algae to increase production rates and optimize wastewater treatment opportunities. Most companies in the sector, as well as another IHI subsidiary, IHI NeoG (Kawasaki, Representative Tomohiro Fujita) use proprietary strains of algae that have high lipid outputs and need special attention. At Daphne, the approach is focused on a systems approach. Floating membrane photobioreactors accept wastewater from a local community municipal wastewater utility, drawing nutrients from the wastewater to promote algae growth. The algae consume nutrients in the wastewater, reducing the cost of treating wastewater. In this approach, municipal wastewater becomes an asset to produce energy, rather than a commodity to be expensively processed. Photosynthesis a gift from the Sun acts to create the chemical reactions that can power our future.

Use of Offshore Photobioreactors Help Lower Amount of Land Use Needed

The use of offshore photobioreactors means that a valuable land footprint would not be required to deploy the system commercially, and the motion of waves and wind provides ideal temperature and mixing controls as well as a reduction of operating costs. From an environmental perspective, ecological dead zones can also be eliminated.

This demonstration plant is just one of a few algae plants throughout the world and will be the first of its kind to create a carbon negative fuel by treating wastewater, making it one of the most sophisticated operational plants that bridge the water-energy nexus and fight global warming.

Significant Advances in Bio-Fuel Production

Another feature of the demonstration facility is significant advancements made in the production of fuels from biomass. Algae Systems has demonstrated a new proprietary technology for the conversion of wet algae and other biomass feedstocks into bio-crude oil, and has successfully demonstrated upgrading the bio-crude oil into diesel, jet and gasoline. The US Department of Energy recently announced that a research consortium coordinated by Algae Systems and led by SRI International will receive $3.2M in grant funding in 2014 to advance this hydrothermal liquefaction process.

About Algae Systems

Algae Systems, founded in 2009, is a technology start-up company that has developed and demonstrated groundbreaking systems for the simultaneous treatment of wastewater and production of "drop-in" transportation fuels. Solving problems at the heart of the "water-energy nexus", Algae Systems operates one of the world's most advanced algae-to-fuel facilities in Daphne, Alabama, where they have a 1-acre facility on Mobile Bay treating 40,000 gallons of wastewater per day and producing ASTM-standard diesel, jet and gasoline fuels from sunlight and CO2. The integrated system produces both carbon-negative fuels and energy-positive wastewater treatment with agricultural fertilizers as a by-product.

About IHI

IHI, established in 1853, is a multi-national leader in providing energy and chemical plants, physical distribution systems and steel structures and produced machinery. With annual net sales of nearly $13 billion (U.S. dollars) and more than 26,900 employees, IHI contributes to the stable supply of electric power by providing the primary equipment for thermal and nuclear power systems, aero-engine and space technology, industrial machinery, shipbuilding and marine engineering.
