Innovative Development in Energy-Related Applied Science

The IDEAS program - short for Innovative Development in Energy-Related Applied Science - provides a continuing opportunity for the rapid support of early-stage applied research to explore pioneering new concepts with the potential for transformational and disruptive changes in energy technology. IDEAS awards, which are restricted to maximums of one year in duration and $500,000 in funding, are intended to be flexible and may take the form of analyses or exploratory research that provides the agency with information useful for the subsequent development of focused technology programs. IDEAS awards may also support proof-of-concept research to develop a unique technology concept, either in an area not currently supported by the agency or as a potential enhancement to an ongoing focused technology program. This program identifies potentially disruptive concepts in energy-related technologies that challenge the status quo and represent a leap beyond today's technology. That said, an innovative concept alone is not enough. IDEAS projects must also represent a fundamentally new paradigm in energy technology and have the potential to significantly impact ARPA-E's mission areas.

Macroalgae Research Inspiring Novel Energy Resources

The projects that comprise ARPA-E's MARINER (Macroalgae Research Inspiring Novel Energy Resources) program seek to develop the tools to enable the United States to become a global leader in the production of marine biomass. Presently, macroalgae, or seaweed, is primarily used as food for human consumption, but there is a growing opportunity for the production of macroalgae for use as feedstock for fuels and chemicals, as well as animal feed. ARPA-E estimates the United States has suitable conditions and geography to produce at least 500 million dry metric tons of macroalgae per year. Such production volumes could yield about 2.7 quadrillion BTUs (quads) of energy in the form of liquid fuel, roughly 10% of the nation's annual transportation energy demand.MARINER project teams will develop technologies capable of providing economically viable, renewable biomass for energy applications without the need for land, fresh water, and synthetic fertilizers. Such technologies include integrated cultivation and harvesting systems, advanced component technologies, computational modeling tools, aquatic monitoring tools, and advanced breeding and genetic tools. Successful technologies must help greatly reduce the capital and operational expenses related to macroalgae production and enable significant increases in farm size and potential areas of deployment.

Methane Opportunities for Vehicular Energy

The projects that comprise ARPA-E's MOVE Program, short for "Methane Opportunities for Vehicular Energy," are finding cost-effective ways to power passenger cars and other light-duty vehicles with America's abundant natural gas resources. Natural gas is currently less expensive than gasoline, and produces fewer harmful emissions than any other fossil fuel. Despite these advantages, significant technological and infrastructure barriers currently limit the use of natural gas as a major fuel source in the U.S. ARPA-E's MOVE projects are finding innovative ways to break through these barriers, creating practical and affordable natural gas storage tanks for passenger cars and quick-filling at-home refueling stations.

Open Funding Solicitation

In 2009, ARPA-E issued an open call for the most revolutionary energy technologies to form the agency's inaugural program. The first open solicitation was open to ideas from all energy areas and focused on funding projects already equipped with strong research and development plans for their potentially high-impact technologies. The projects chosen received a level of financial support that could accelerate technical progress and catalyze additional investment from the private sector. After only 2 months, ARPA-E's investment in these projects catalyzed an additional $33 million in investments. In response to ARPA-E's first open solicitation, more than 3,700 concept papers flooded into the new agency, which were thoroughly reviewed by a team of 500 scientists and engineers in just 6 months. In the end, 36 projects were selected as ARPA-E's first award recipients, receiving $176 million in federal funding.

Plants Engineered to Replace Oil

The 10 projects that comprise ARPA-E's PETRO program, short for "Plants Engineered to Replace Oil," aim to develop non-food crops that directly produce transportation fuel. These crops can help supply the transportation sector with plant-derived fuels that are cost-competitive with petroleum and do not affect U.S. food supply. PETRO aims to redirect the processes for energy and carbon dioxide (CO2) capture in plants toward fuel production. This would create dedicated energy crops that serve as a domestic alternative to petroleum-based fuels and deliver more energy per acre with less processing prior to the pump.

Renewable Energy to Fuels Through Utilization of Energy-Dense Liquids

Most liquid fuels used in transportation today are derived from petroleum and burned in internal combustion engines. These energy-dense fuels are currently economical, but they remain partially reliant on imported petroleum and are highly carbon intensive. Alternatives to internal combustion engines, like fuel cells, which convert chemical energy to electricity, have shown promise in vehicle powertrains, but are hindered by inefficiencies in fuel transport and storage. Projects in the Renewable Energy to Fuels Through Utilization of Energy-Dense Liquids (REFUEL) program seek to develop scalable technologies for converting electrical energy from renewable sources into energy-dense carbon-neutral liquid fuels (CNLFs) and back into electricity or hydrogen on demand. REFUEL projects will accelerate the shift to domestically produced transportation fuels, improving American economic and energy security and reducing energy emissions.

Reducing Emissions using Methanotrophic Organisms for Transportation Energy

The projects that comprise ARPA-E's REMOTE program, short for "Reducing Emissions using Methanotrophic Organisms for Transportation Energy," seek to enable highly efficient biological conversion of methane to liquid fuels for small-scale deployment. Specifically REMOTE focuses on improving the energy efficiency and carbon yield of biological routes from methane to a useable form for fuel synthesis while also examining high-productivity methane conversion processes and bioreactor technologies.

Rhizosphere Observations Optimizing Terrestrial Sequestration

America's vast terrestrial resources (over 520 million hectares of crop, range and forestland) are strategic assets essential for sustainable economic growth. While advances in technology have resulted in a ten-fold increase in crop productivity over the past hundred years, soil quality has declined, incurring a soil carbon debt equivalent to 65 parts per million (ppm) of atmospheric carbon dioxide (CO2). The soil carbon debt also increases the need for costly nitrogen fertilizer, which has become the primary source of nitrous oxide (N2O) emissions, a greenhouse gas. The soil carbon debt also impacts crop water use, increasing susceptibility to drought stress, which threatens future productivity. Given the scale of domestic (and global) agriculture resources, there is tremendous potential to reverse these trends by harnessing the photosynthetic bridge between atmospheric carbon, plants, microbes and soil. Development of new root-focused plant cultivars could dramatically and economically reduce atmospheric CO2 concentrations while improving productivity, resilience and sustainability. To this end, projects in the ARPA-E Rhizosphere Observations Optimizing Terrestrial Sequestration (ROOTS) program seek to develop advanced technologies and crop cultivars that enable a 50 percent increase in soil carbon accumulation while reducing N2O emissions by 50 percent and increasing water productivity by 25 percent.

Transportation Energy Resources from Renewable Agriculture

The TERRA program is facilitating improvement of advanced biofuel crops, specifically energy sorghum, by developing and integrating cutting-edge remote sensing platforms, complex data analytics tools, and high-throughput plant breeding technologies. Project teams are constructing automated systems to accurately measure and analyze crop growth in the field, thoroughly characterizing genetic potential and creating algorithms for selecting the best plants to reproduce. These innovations will accelerate domestic production of sustainable, renewable, and affordable liquid transportation fuels. The program will also generate the world's largest public reference database of sorghum plant characteristics and genetic composition that will facilitate research and development efforts across public and private sector institutions and in other important agricultural crops.

Adaptive Surface Technologies, Inc

Marine and Hydrokinetic Energy Conversion and Environmental Monitoring Technology Advancement

The Harvard project team, now a new company called Adaptive Surface Technologies, is developing a slippery coating that can be used for a number of technology applications including oil and water pipelines, wastewater treatment systems, solar panels (to prevent dust accumulation), refrigeration (to prevent ice buildup), as well as many other energy-relevant applications. Contamination, build-up of microorganisms, and corrosion of untreated surfaces can lead to inefficiencies in the system. Harvard's liquid-based coating is tailored to adhere to and then spread out evenly over a rough surface, forming a completely smooth surface that inhibits buildup. Since it is liquid-based, it can easily repair itself if scratched or damaged, resulting in a stable coating with the potential to significantly outperform conventional technologies, such as Teflon, in friction and drag reduction and in repelling a broad range of contaminants.

Agrivida

Conditionally Activated Enzymes Expressed in Cellulosic Energy Crops

Enzymes are required to break plant biomass down into the fermentable sugars that are used to create biofuel. Currently, costly enzymes must be added to the biofuel production process. Engineering crops to already contain these enzymes will reduce costs and produce biomass that is more easily digested. In fact, enzyme costs alone account for $0.50-$0.75/gallon of the cost of a biomass-derived biofuel like ethanol. Agrivida is genetically engineering plants to contain high concentrations of enzymes that break down cell walls. These enzymes can be "switched on" after harvest so they won't damage the plant while it's growing.

Algaeventure Systems

Scaling and Commercialization of Algae Harvesting Technologies

Led by CEO Ross Youngs, AVS has patented a cost-effective dewatering technology that separates micro-solids (algae) from water. Separating micro-solids from water traditionally requires a centrifuge, which uses significant energy to spin the water mass and force materials of different densities to separate from one another. In a comparative analysis, dewatering 1 ton of algae in a centrifuge costs around $3,400. AVS's Solid-Liquid Separation (SLS) system is less energy-intensive and less expensive, costing $1.92 to process 1 ton of algae. The SLS technology uses capillary dewatering with filter media to gently facilitate water separation, leaving behind dewatered algae which can then be used as a source for biofuels and bio-products. The biomimicry of the SLS technology emulates the way plants absorb and spread water to their capillaries.

Arcadia Biosciences

Vegetative Production of Oil in a C4 Crop

Arcadia Biosciences, in collaboration with the University of California-Davis, is developing plants that produce vegetable oil in their leaves and stems. Ordinarily, these oils are produced in seeds, but Arcadia Biosciences is turning parts of the plant that are not usually harvested into a source of concentrated energy. Vegetable oil is a concentrated source of energy that plants naturally produce and is easily separated after harvest. Arcadia Biosciences will isolate traits that control oil production in seeds and transfer them into leaves and stems so that all parts of the plants are oil-rich at harvest time. After demonstrating these traits in a fast-growing model plant, Arcadia Biosciences will incorporate them into a variety of dedicated biofuel crops that can be grown on land not typically suited for food production.

Arizona State University

Cyanobacteria Designed for Solar-Powered Highly Efficient Production of Biofuels

ASU is engineering a type of photosynthetic bacteria that efficiently produce fatty acids--a fuel precursor for biofuels. This type of bacteria, called Synechocystis, is already good at converting solar energy and carbon dioxide (CO2) into a type of fatty acid called lauric acid. ASU has modified the organism so it continuously converts sunlight and CO2 into fatty acids--overriding its natural tendency to use solar energy solely for cell growth and maximizing the solar-to-fuel conversion process. ASU's approach is different because most biofuels research focuses on increasing cellular biomass and not on excreting fatty acids. The project has also identified a unique way to convert the harvested lauric acid into a fuel that can be easily blended with existing transportation fuels.

ARZEDA Corp.

Design of Metalloenzymes for Methane Activation

The team from Arzeda will use computational enzyme design tools and their knowledge of biological engineering and chemistry to create new synthetic enzymes to activate methane. Organisms that are capable of using methane as an energy and carbon source are typically difficult to engineer. To address this challenge, Arzeda will develop technologies essential to creating modular enzymes that can be used in other organisms. The team will combine computation enzyme design with experimental methods to improve enzyme activity and help direct methane more effectively into metabolism for fuel production. Arzeda's new enzymes could transform the way methane is activated, and would be more efficient than current chemical and biological approaches.

Bettergy Corp.

Low Temperature Ammonia Cracking Membrane Reactor for Hydrogen Generation

Bettergy Corp. will develop a catalytic membrane reactor to allow on-site hydrogen generation from ammonia. Ammonia is much easier to store and transport than hydrogen, but on-site hydrogen generation will not be viable until a number of technical challenges have been met. The team is proposing to develop a system that overcomes the issues caused by the high cracking temperature and the use of expensive catalysts. Bettergy proposes a low temperature, ammonia-cracking membrane reactor system comprised of a non-precious metal ammonia cracking catalyst and a robust composite membrane. A one-step cracking process will be used to convert ammonia into hydrogen and nitrogen, with the hydrogen passing through the selective membrane leaving only nitrogen as the byproduct. If the team is successful, the conversion efficiency will be higher than conventional methods because the hydrogen is removed from the system as it is being produced. The low-temperature reactor will provide greater reliability, ease of operation, and cost effectiveness to hydrogen fueling stations. The team's technology could also be applicable for stationary fuel cell systems and the semiconductor, metallurgy, chemical, aerospace, and telecommunications industries.
