ARPA-E to award $25M for macroalgae projects; seaweed biomass to be cost-competitive with terrestrial biomass at energy-relevant scales

December 16, 2016

ARPA-E announced up to $25 million in funding for the MacroAlgae Research Inspiring Novel Energy Resources (MARINER) program (DE-FOA-0001726). The program will focus on developing advanced cultivation technologies that enable the cost and energy efficient production of macroalgal biomass in the ocean at a scale suitable as feedstock for the production of fuels and chemicals. The deadline to submit a Concept Paper for MARINER is 5 pm ET, 14 February 2017.

The US has the world’s largest marine Exclusive Economic Zone—an area of ocean along the nation’s coast lines which is equivalent to the total land area of all 50 states. The US has the potential to utilize this resource to build and grow a thriving marine biomass industry for the production of fuels, chemicals, feed, and food. Growing macroalgal biomass in the oceans offers a unique opportunity to sidestep many of the challenges associated with terrestrial biomass production systems, particularly the growing competition for land and freshwater resources, which are likely to result from the 50 to 100% increase in demand for food expected for 2050.

Argonne LCA finds renewable diesel from algae fractionation has 63-68% lower GHG than petroleum diesel

October 22, 2016

A new analysis from Argonne National Laboratory, funded by the US Department of Energy’s Bioenergy Technologies Office (BETO), shows the potential of an algae fractionation process to produce renewable diesel fuel with 63%–68% lower greenhouse gas (GHG) emissions than conventional diesel. The study is published in the journal Algal Research.

In some algal biofuel production methods, lipids are extracted from algae and converted to renewable diesel, while the non-lipid components of the algae are converted to biogas. The biogas is used for renewable heat and electricity to power the conversion process of the lipids to renewable diesel.

ARPA-E to issue funding opportunity for advanced technologies for seaweed cultivation for fuels and chemicals

September 09, 2016

The Advanced Research Projects Agency – Energy (ARPA–E) intends to issue a new Funding Opportunity Announcement (FOA ) in November, 2016, for the development of advanced cultivation technologies that enable profitable and energy efficient production of macroalgal-biomass (seaweeds) in the ocean. ARPA–E held a workshop on this topic in February 2016.

These technologies are expected to be deployed and support cultivation of macroalgal-biomass feedstocks at a scale relevant for the production of commodity fuels and chemicals. The primary challenge is to reduce capital and operating cost of macroalgae cultivation dramatically, while significantly increasing the range of deployment by expanding into more exposed, off-shore environments.

DOE to award up to $6.7M to projects to convert captured CO2 to useful products, including fuels

August 26, 2016

The US Department of Energy (DOE) will award approximately $6.7 million in federal funding for cost-shared projects that will develop technologies that utilize CO2 from coal-fired power plants to produce useful products. DOE’s Office of Fossil Energy is seeking these projects as part of the Department’s Carbon Storage program, which has the goal of developing and advancing technologies to improve the effectiveness of carbon storage, reduce the cost of implementation, and be ready for widespread commercial deployment in the 2025–2035 timeframe.

After carbon dioxide is captured from large point sources, such as coal-fired power plants, it can be injected into underground geological formations from which it cannot escape (geologic sequestration). Another option is to use the CO2 as a reagent to create useful products, such as cement, plastics, or liquid fuels. The new DOE funding opportunity announcement (DE-FOA-0001622) focuses on the second of these pathways which is focused on securing applications for projects that will develop CO2-utilization technologies that produce useful products at lower cost than currently available technologies, without generating additional greenhouse gas emissions.

RIT and Synergy Biogas partner on algae for wastewater cleanup and biofuel production

June 03, 2016

Rochester Institute of Technology (RIT) and Synergy Biogas are exploring the environmental benefits of microalgae to clean agricultural wastewater and make biofuels. Jeff Lodge, associate professor in RIT’s Thomas Gosnell School of Life Sciences, is running a three-month pilot program at Synergy Biogas, a high-tech anaerobic digester located on Synergy Farms in Covington, N.Y, to grow microalgae on digested biomass. Microalgae will consume contaminants in wastewater and produce an algal biomass that Lodge will use as a feedstock for renewable energy.

Lodge will grow the microalgae in a 1,000-gallon tank at Synergy in a process that can be scaled up to treat 52,000 gallons, or 200,000 liters, of wastewater a day. The trial project will demonstrate the organisms’ ability to consume ammonia, phosphorous and nitrogen from digested biomass and reduce contaminants below state-mandated levels. Lodge’s laboratory experiments with microalgae have reduced phosphorous in wastewater by greater than 90% to levels of 0.1 parts per million, exceeding the required 1 parts per million in New York.
