Pinnacle Engines
Pinnacle Engines will develop a highly efficient hybrid electric engine that, if successful, will significantly reduce petroleum consumption and carbon dioxide emissions in the U.S. Adding a unique electric powertrain to Pinnacle’s four-stroke, spark-ignited, opposed-piston sleeve-valve engine technology enables a fundamental leap forward in fuel efficiency. Electric motor-generators on each crankshaft will improve engine efficiency by modifying and optimizing the piston motion and resulting combustion process.

National Renewable Energy Laboratory (NREL)
The National Renewable Energy Laboratory (NREL) is developing a low-cost battery system that uses safe and inexpensive organic energy storage materials that can be pumped in and out of the system. NREL’s battery, known as a “liquid-phase organic redox system,” uses newly developed non-flammable compounds from biological sources to reduce cost while improving the amount of energy that can be stored. The battery’s unique construction will enable a 5-minute “fast-charge” and promote long life by allowing for the rapid replacement of liquid electrodes.
University of Wisconsin-Madison (UW-Madison)
The University of Wisconsin-Madison (UW-Madison) and its project team will develop new integrated motor drives (IMDs) using current-source inverters (CSIs). Recent advances in both silicon carbide (SiC) and gallium nitride (GaN) wide-bandgap semiconductor devices make these power switches well-suited for the selected CSI topology that the team plans to integrate into high-efficiency electric motors with spinning permanent magnets.

Georgia Tech Research Corporation
Georgia Institute of Technology aims to develop a simple, scalable, and modular device that can remove CO2 from the atmosphere. The device will be designed such that ambient wind is sufficient to contact the CO2-laden air with the materials that filter CO2 out. The filtered CO2 will then be concentrated using localized electric heating, which allows the device to be easily deployed and integrated with renewables or the existing electrical grid.
University of Pennsylvania
The University of Pennsylvania will develop a comprehensive building structure strategy with high-performance, prefabricated, funicular structures for minimized mass and maximized surface area for carbon absorption. The team will use innovative carbon-absorbing, 3D printable concrete as a primary structural material and bio-based carbon-storing materials for the building's envelope and finishes. Additive manufacturing technology will be used in fabrication to reduce waste.

Gas Technology Institute (GTI)
Gas Technology Institute (GTI) is developing a continuously operating cell that produces low-cost aluminum powder using less energy than conventional methods. Conventional aluminum production is done by pumping huge electrical currents into a vat of molten aluminum dissolved in mineral salts at nearly 2000 degrees Fahrenheit. GTI’s technology occurs near room temperature using reusable solvents to dissolve the ore.

Illinois Institute of Technology (IIT)
Illinois Institute of Technology (IIT) is collaborating with Argonne National Laboratory to develop a rechargeable flow battery for EVs that uses a nanotechnology-based electrochemical liquid fuel that offers over 30 times the energy density of traditional electrolytes. Flow batteries, which store chemical energy in external tanks instead of within the battery container, are typically low in energy density and therefore not well suited for transportation.
Battelle Memorial Institute
Battelle Memorial Institute is developing a new air conditioning system that uses a cascade reverse osmosis-based absorption cycle. Analyses show that this new cycle can be as much as 60% more efficient than vapor compression, which is used in 90% of air conditioners. Traditional vapor-compression systems use polluting liquids for a cooling effect. Absorption cycles use benign refrigerants such as water, which is absorbed in a salt solution and pumped as liquid—replacing compression of vapor.

University of Missouri
The University of Missouri will develop a hybrid mechanical-capillary-drive two-phase loop that could serve as an ideal cooling solution for data centers. The proposed technology offers numerous advantages over existing phase-change processes such as flow boiling and condensation, including dual-mode operation, low thermal resistance, high heat flux, low pumping power consumption, high power density, reliable operation, and a fully scalable design.

GreenLight Biosciences
GreenLight Biosciences is developing a cell-free bioreactor that can convert large quantities of methane to fuel in one step. This technology integrates biological and chemical processes into a single process by separating and concentrating the biocatalysts from the host microorganisms. This unique “cell-free” approach is anticipated to improve the productivity of the reactor without increasing cost. GreenLight’s system can be erected onsite without the need for massive, costly equipment. The process uses natural gas and wellhead pressure to generate the power needed to run the facility.
Sheetak
Sheetak is developing a thermoelectric-based solid state cooling system that is more efficient, more reliable, and more affordable than today’s best systems. Many air conditioners are based on vapor compression, in which a liquid refrigerant circulates within the air conditioner, absorbs heat, and then pumps it out into the external environment. Sheetak’s system, by contrast, relies on an electrical current passing through the junction of two different conducting materials to change temperature.
