Crossing the 3K threshold: The Digest’s Multi-Slide Guide to Sapphire Energy’s algae biofuels productivity

Aug 23, 2017

August 23, 2017 | Jim Lane Back in 2014, Sapphire Energy and the US Department of Energy embarked on a project to advance Sapphire’s (then) biomass production technologies across three priority areas to meet a target of 2,500 gallons of oil per acre per year by 2018. Productivity is directly related to the economics of algal biofuels production. By improving average productivity, cost of fuel production is greatly decreased. The three priority areas were: improving Algal Biomass Productivity; improving Pre-Processing Technologies; and integration of Algal Biomass Unit Operations.  The project outcome was very positive. Sapphire indeed achieved annual average productivity of 12 g/m2/day, producing equivalent of 3031 gal/acre/year of HTT product, over one year in 127m2 raceways in Las Cruces, NM. Sapphire Energy’s Craig Behnke gave these illuminating slides on the Sapphire/DOE project at the DOE Project Peer Review meetings in Washington, DC. Prev1 of 21 Next

Capturing Carbon Dioxide to Fuel the World The amazing technological and economic progress achieved in the past 100 years has largely been fueled by hydrocarbons. However the sustainability of this progress is now coming into question, both due to the rise in greenhouses gases caused by hydrocarbon combustion and the predicted depletion of fossil hydrocarbon sources. Sequesco's goal is to develop technologies which help enable hydrocarbons to continue fueling human progress, while alleviating the problems of greenhouse gas emissions, growing geological scarcity, and the drawbacks of agriculturally produced biofuels. The company's guiding principle is to use microbes as master chemists in sustainable systems that serve the dual role of sequestering carbon dioxide and producing transportation fuels.


Aerophase, Inc. is a Longmont, CO based company that has received a grant(s) from the Department of Energy's SBIR/STTR program. The abstract(s) for these grant award(s) are provided as well since they provide insights into Aerophase, Inc.'s business and areas of expertise. Biodiesel is a key component in US plans to reduce dependence on foreign oil and decrease the environmental impacts of using fossil fuels—but current feedstocks and production technologies prevent it from being cost-competitive. This project will provide enabling technologies for a costeffective, energy-efficient method of producing biodiesel fuels from a variety of lowercost feedstocks. Biodiesel is a key component in U.S. plans to reduce dependence on foreign oil and decrease the environmental impacts of using fossil fuels—but current production technology is not cost-competitive.

EnerTech Environmental

EnerTech Environmental is a renewable energy company focused on the development and commercialization of clean combustion technologies for biosolids (sewage sludge) and other organic wastes. EnerTech's patented SlurryCarb process aims to cleanly and economically converts high-moisture wastes into a high-grade renewable fuel, with significant cost savings over alternative options. Biosolids and other feedstocks undergo a molecular rearrangement that transforms these high-moisture materials into a renewable fuel suitable for the replacement of fossil fuels. By processing biosolids as a fluid, the technology aims to provide savings in both capital and operating costs. The resulting fuel, called E-Fuel, is a clean, renewable fuel that is an excellent replacement for fossil fuels. As a renewable fuel, E-Fuel produces essentially zero net greenhouse gas emissions.


OriginOil, Inc. aims to develop technology that will transform algae into renewable oils.


Seambiotic is trying to reduce CO quantities of the harvested algae from the Ashkelon power plant. The algae has been sent to laboratories, factories and research authorities for the extraction and processing of oils and sugars to bio-diesel and bio-ethanol respectively.


Vaperma Inc aims to provide gas separation technology for the production of fuel ethanol biodiesel and natural gas. The company's advanced polymeric membrane systems is designed to enable major energy costs savings and reduction of green house gases and benzene emissions
