Algae demonstration commissioned at West Oahu refinery


Chevron & KuehnleKuehnle AgroSystems, Inc. (KAS), a producer of specialized algae strains and bulk concentrated algae designed to meet the diverse needs of the animal nutrition, specialty chemical and biofuels markets, has announced the commissioning of an algae demonstration project at the Chevron Hawaii refinery.

The demonstration project, funded by the Hawaii Renewable Energy Development Venture and the Office of Naval Research, produces algae using recycled CO2 waste streams and wastewater by-product from Chevron’s refinery to cultivate algae in specially designed closed growing systems. Chevron’s role in this project is to serve as a host site and a source of recycled CO2 and wastewater for KAS to conduct its research.

“We believe this project is the first U.S. demonstration of refinery waste streams being recycled into valuable algae products” said Dr. Adelheid Kuehnle, founder and CEO of KAS. “We’re thankful to the Chevron Hawaii refinery for making their facility available to us as a host site.”

The live algae used in this project are sourced in Hawaii. KAS has designed and will operate the demonstration project through August 2012 to cultivate and evaluate different strains of algae at production scale.

Partners in this project include Rhode Island-based BioProcess Algae for test cultivation systems; Alabama-based Inventure Chemical for biomass conversion to a high quality intermediate fuel; the University of Hawaii’s Hawaii Natural Energy Institute for water recycling and bioplastics production from waste; and Honolulu-based AMEL Technologies for engineering support.

Hawaii’s Chevron refinery is one of only a few places ideally suitable for this particular demonstration project, due to the consistent sunlight associated with west Oahu and an available supply of CO2 waste streams, both ideal for algae cultivation.

Chevron has not made any financial commitments to KAS, nor does it endorse the technology at this early stage of the research project. KAS’ goals for this project include transitioning algae as a sustainable resource; linking industrial effluents for scalable algae production; and linking biomass produced from KAS algae species with highly effective conversion processes to produce biofuels.
