## DOE to issue funding solicitation for algal biofuels and bioproducts; targeting <$5 gge by 2019 ##### 20 August 2014 The US Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE) intends to issue, on behalf of the DOE Bioenergy Technologies Office (BETO), a Funding Opportunity Announcement (FOA) (DE-FOA-0001162) entitled “Targeted Algal Biofuels and Bioproducts (TABB)”. The TABB FOA seeks to reduce the cost of algal biofuels. BETO’s 2019 projected state of technology (SOT) for the cost of algal biofuels is modeled at about$8 per gallon gasoline gallon equivalent (gge) based on a lipid extraction pathway without valuable co-products. The TABB FOA will support work at bench and process development scales to develop valuable co-products, crop protection, and CO2 utilization strategies. BETO expects the TABB FOA to result in modeled mature algal biofuel costs of less than $5 gge by 2019. Achieving this would provide alternative, nearer-term pathways to achieve BETO’s longer-term goal of$3 gge advanced algal biofuels validation by 2030.

Current and previous BETO research and development (R&D) has established that algal feedstocks are a technically feasible alternative to petroleum-based diesel and jet fuels, as well as a range of commodity and specialty chemicals, animal- and fish-feeds, and polymers (i.e., bioproducts); however, this work has also highlighted that enduring barriers to broad commercialization remain. These barriers are related to biology, cultivation, and processing.

Developing technology to achieve higher biomass yields in scalable cultivation systems and higher overall values for the processed biomass are critical strategies to overcoming the barriers, according to the DOE.

Specific areas of interest in the TABB FOA will be:

1. The development of algae cultures that produce valuable bioproduct precursors alongside fuel components to increase the overall value of the biomass; and

2. The development of crop protection and CO2 utilization technologies to boost culture productivity and yield to reduce the cost of the biomass.

EERE envisions awarding multiple 4-year awards. Awards in the first area of interest are expected to be range between $5,000,000 and$10,000,000; awards in the second area are expected to range between $500,000 and$1,000,000. A minimum cost share of 20% will be required for both interest areas.
