REBELS

Reliable Electricity Based on ELectrochemical Systems

Fuel cell technologies have been touted for decades due to their high chemical-to-electrical conversion efficiencies and potential for near-zero greenhouse gas emissions. Fuel cell technologies for power generation have not achieved widespread adoption, however, due primarily to their high cost relative to more established combustion technologies. There is a critical need to develop fuel cell technologies that can enable distributed power generation at low cost and high performance. The projects that comprise ARPA-E’s Reliable Electricity Based on ELectrochemical Systems (REBELS) program…

REEACH

Range Extenders for Electric Aviation with Low Carbon and High Efficiency

The REEACH program objective is to develop a disruptive system to convert the chemical energy contained in energy-dense carbon neutral liquid fuels (CNLFs) into electric power for aircraft propulsion via electric powertrains and other key systems. With a developmental prototype as the ultimate goal, REEACH performers will work to create innovative, cost-effective and high-performance energy storage and power generation (ESPG) sub-systems. The developed ESPG system must deliver adequate electric power to propel a fully electric, narrow-body aircraft through all the various flight phases (i.e…

REFUEL

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…

REPAIR

Rapid Encapsulation of Pipelines Avoiding Intensive Replacement

Cast iron, wrought iron, and bare steel natural gas distribution pipes—legacy pipes—make up 3% of  the nearly 2 million miles of utility pipes in use, but account for a disproportionate number of gas leaks and pipe failures compared to more recently replaced infrastructure. REPAIR seeks to reduce natural gas leaks from these pipes by developing a suite of technologies to enable the automated construction of new pipe inside existing pipe. The new pipe must meet utilities’ and regulatory agencies’ requirements, have a minimum life of 50 years, and have sufficient material properties to…

ROOTS

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…

SHARKS

Submarine Hydrokinetic And Riverine Kilo-megawatt Systems

SHARKS seeks to develop new technical pathways to design economically competitive Hydrokinetic Turbines (HKT) for tidal and riverine currents. These renewable energy resources are highly reliable, forecastable, and typically co-located with demand centers. HKTs are suited for both micro-grids that supply energy to remote communities without grid connections and utility-scale grid-connected applications. Despite these attractive qualities, current HKTs are too expensive for deployment due to technical challenges and harsh operational environments. This program seeks to fund new holistic HKT…

SHIELD

Single-Pane Highly Insulating Efficient Lucid Designs

The SHIELD Program, short for “Single-Pane Highly Insulating Efficient Lucid Designs,” aims to develop innovative materials that will improve the energy efficiency of existing single-pane windows in commercial and residential buildings. Technologies created through the SHIELD program seek to cut in half the amount of heat lost through single-pane windows in cold weather. These materials would improve insulation, reduce cold weather condensation, and enhance occupant comfort. The technologies could also produce secondary benefits, such as improved soundproofing, that will make retrofits more…

SMARTFARM

Systems for Monitoring and Analytics for Renewable Transportation Fuels from Agricultural Resources and Management

The SMARTFARM program’s objective is to bridge the data gap in the biofuel supply chain by funding technologies that can quantify feedstock-related emissions at the field-level and enable new market incentives for efficiency in feedstock production and carbon management. The value of such technologies lies in their ability to reliably, accurately (i.e., low uncertainty), and cost-effectively quantify feedstock production life cycle emissions (in g CO2e/acre) at the field level (i.e., scalable to >80 acres).The SMARTFARM program is structured in two initial phases: 1. Phase 1 will…
