“Sustainability in Bioenergy: A Nation Connected” is a short documentary highlighting personal stories and the efforts being made by communities across the United States to develop, produce, and provide bioenergy, while ensuring it is environmentally, economically, and socially sustainable. From farmers and families in the Midwest, to researchers and business-owners on the coasts, “Sustainability in Bioenergy: A Nation Connected” is a prelude to future products that will provide first-hand views on how sustainability in bioenergy unites us as a nation. This video was developed by the U.S. Department of Energy Bioenergy Technologies Office and supports initiatives to expand the public’s understanding of sustainable transportation and the bioenergy industry.

Converting large tracts of the Midwest’s marginal farming land to perennial biofuel crops carries with it some key unknowns, including how it could affect the balance of water between rainfall, evaporation and movement of soil water to groundwater.
In humid climates such as the U.S. Midwest, evaporation returns more than half of the annual precipitation to the atmosphere, with the remainder available to recharge groundwater and maintain stream flow and lake levels.
A recent study from the Great Lakes Bioenergy Research Center and published in Environmental Research Letters looks at how efficiently “second generation” biofuel crops – perennial, non-food crops such as switchgrass or native grasses – use rainwater and how these crops affect overall water balance.
The Energy Department has announced six projects that will receive up to $18 million in funding to reduce the modeled price of algae-based biofuels to less than $5 per gasoline gallon equivalent (gge) by 2019. This funding supports the development of a bioeconomy that can help create green jobs, spur innovation, improve the environment, and achieve national energy security.
Algal biomass can be converted to advanced biofuels that offer promising alternatives to petroleum-based diesel and jet fuels. Additionally, algae can be used to make a range of other valuable bioproducts, such as industrial chemicals, bio-based polymers, and proteins. However, barriers related to algae cultivation, harvesting, and conversion to fuels and products need to be overcome to achieve the Department’s target of $3 per gge for advanced algal biofuels by 2030. To accomplish this goal, the Department is investing in applied research and development technologies that can achieve higher yields of targeted bioproducts and biofuels from algae—increasing the overall value for algae biomass.
The projects selected include:
- Producing Algae and Co-Products for Energy (PACE), Colorado School of Mines, Golden, CO – Colorado School of Mines, in collaboration with Los Alamos National Laboratory, Reliance Industries Ltd., and others, will receive up to $9 million to enhance overall algal biofuels sustainability by maximizing carbon dioxide, nutrient, and water recovery and recycling, as well as bio-power co-generation.
- Marine Algae Industrialization Consortium (MAGIC), Duke University, Durham, NC – Duke University will receive up to $5.2 million to lead a consortium including University of Hawaii, Cornell University, Cellana and others to produce protein-based human and poultry nutritional products along with hydrotreated algal oil extract.
- Global Algae Innovations, Inc., El Cajon, CA – Global Algae Innovations will receive up to $1 million to increase algal biomass yield by deploying an innovative system to absorb carbon dioxide from the flue gas of a nearby power plant.
- Arizona State University, Mesa, AZ – Arizona State University will receive up to $1 million for atmospheric carbon dioxide capture, enrichment, and delivery to increase biomass productivity.
- University of California, San Diego, San Diego, CA – The University of California, San Diego will receive up to $760,000 to develop an automated early detection system that can identify and characterize infestation or infection of an algae production pond in order to ensure crop health.
- Lawrence Livermore National Laboratory, Livermore, CA – Lawrence Livermore National Laboratory will receive up to $1 million to protect algal crops by developing “probiotic” bacteria to combat pond infestationand increase ecosystem functioning and resilience.
The Energy Department’s Office of Energy Efficiency and Renewable Energy accelerates development and facilitates deployment of energy efficiency and renewable energy technologies and market-based solutions that strengthen U.S. energy security, environmental quality, and economic vitality.

Beer—is there anything it can’t do?
You can chug it to improve the watchability of baseball, use it to de-ice roads, and now even power your car with it, thanks to the New Zealand biofuel “Brewtroleum.” The ethanol used in the greener gas, which was dreamed up by DB Export, is derived from leftovers of the brewing process, chiefly grain and yeast.
