The MIT will develop a new generation of power electronics based on vertical gallium nitride (GaN) superjunction diodes and transistors that can vastly exceed the performance of today’s GaN power devices. The new superjunction structure will surpass the theoretical trade-off between on- resistance and breakdown voltage observed in conventional unipolar GaN, leading to more efficient and cheaper power converters. These new GaN power devices will enable the next generation of low-cost, fast, small, and reliable power electronics, which are key for efficient power conversion in data centers, solar farms, power grids, and electric vehicles.

Currently, SMC magnetic cores are expensive and time consuming to manufacture in the complex shapes required for next-generation devices using conventional press and sinter powder metallurgy. If successful, the team’s efforts would result in magnetic cores with 10x lower core loss at frequencies of 500 kHz to 1 MHz at half the price.

  • Argonne National Laboratory. A Zero-emission Process for Direct Reduction of Iron by Hydrogen Plasma in a Rotary Kiln Reactor - $1,200,000. Argonne National Laboratory seeks to disrupt the steel industry by developing a potentially zero-carbon ironmaking process that eliminates the use of coke or natural gas and requires less energy than current processes. The team’s process will use hydrogen plasma to reduce iron ore in a rotary kiln furnace, which will improve the thermodynamics and kinetics of iron ore reduction, potentially eliminate the need for iron ore pelletizing, and enable the process to run at a lower temperature. The team estimates that the combination hydrogen plasma-rotary kiln process can improve energy efficiency and potentially reduce CO2 emissions in the steel industry by more than one billion tons per year. Energy consumption could be reduced by 45% compared with the blast furnace process and by approximately 15% compared with an H2-direct reduced iron process.

The team at will develop the CMP material to have high bulk resistivity, permeability, saturation flux density, and low coercivity for the electric machine cores. Their approach removes the need for laminated cores and will not generate any scrap metal in the core manufacturing process. The EPD insulation is 10 times more thermally conductive than the traditional material. Combined, the new materials and manufacturing methods are expected to improve torque density by 40-70% and reduce manufacturing costs.

  • Carnegie Mellon University. Ionomer-Free Electrodes for Ultrahigh Power Density Fuel Cells - $3,220,310. The CMU team seeks to develop novel ionomer-free electrodes to enable transformative improvements in polymer electrolyte membrane (PEM) fuel cell technology. The project will combine functionalized mixed conductors with advanced ultra-high activity catalysts to move proton conduction functionality to the support surface and remove ionomer from the electrode. This would eliminate the ionomer, which conducts ions, but also poisons catalyst sites and obstructs oxygen transport. Removing the ionomer is also key to accessing the ultra-high oxygen reduction reaction activity of emerging nanostructured platinum-alloy catalysts in PEM fuel cells. The resulting ultra-high-power density would revolutionize PEM fuel cell technology, enabling the deployment of low-cost, high-efficiency fuel cells for light-duty and heavy-duty vehicles.

  • University of Washington. Harvesting Infrared Light to Improve Photosynthetic Biomass Production - $1,347,122. The University of Washington seeks to develop new photosynthetic systems that use sunlight from previously under-utilized or inaccessible portions of the solar spectrum to produce chemical fuel. The team will use the de novo protein design (a computational approach to design proteins from scratch, rather than using a known protein structure) to modify photosynthetic light harvesting machinery for a broader spectrum, allowing more energy to be translated from light to chemical energy. If successful, this project would enable biofuel and bioproduct generation from near-infrared light in cyanobacteria, algae, and plants, showing that it is feasible to reengineer the light-harvesting and charge-separation reactions that are the foundation of natural photosynthesis.

The system takes three main inputs: ambient air, water, and a sustainable energy source, and produces butanol with high selectivity. The proposed process is projected to have a 35% lower global warming potential and a twelvefold reduction in land use compared with a biotechnological process relying on corn-derived glucose.

  • Columbia University. High Capacity Electrolyzers Based on Ultrathin Proton-Conducting Oxide Membranes - $3,375,712. Columbia University seeks to lower the production cost of carbon-free, “green hydrogen” through the development of a low-temperature electrolyzer that uses proton-conducting oxide membranes (POM) with the potential to achieve step-change increases in current density and efficiency compared to today’s commercial polymer electrolyte membrane (PEM) electrolyzers. The project’s approach of decreasing POM thickness by 2-4 orders of magnitude, and subsequently decreasing its resistance by roughly an order of magnitude, would enable efficient low-temperature water electrolysis at current densities higher than those used by conventional PEM electrolyzers.

The University of Houston seeks to create a class of battery that uses magnesium anodes instead of lithium and organic materials in place of transition metal-based cathodes. Early work has shown very fast reaction kinetics, and power capabilities in excess of 5kW/Kg have been demonstrated. The battery would provide a transportation energy storage solution that could be charged very fast and have a comparable energy density with the state-of-the-art lithium ion. Additionally, given growing market pressures in lithium and transition metals, this alternative could enhance the nation’s energy supply chain security. The project team seeks to advance the technology on multiple fronts including electrode material and electrolyte optimization, cycle life extension, practical cell design, and scaling-up material production and cell fabrication.

  • University of Michigan. Battery Separator for Completely Stopping Dendrite - $950,000. The University of Michigan team aims to develop a new type of battery separator that can effectively prevent rather than block the formation of dendrites. These dendrites can cause battery failure and pose a safety hazard due to internal short-circuit. The new separator will be synthesized through a wet process followed by phase alignment. The resulting dendrite-suppression capability could be the equivalent of several orders of magnitude better than existing separators or solid-state electrolytes. If successful, this mechanism could make high-capacity lithium (Li) metal batteries viable, significantly increase the reliable operational window of current Li-ion batteries, and ensure safe operation of Li-ion batteries even when manufacturing defects are present. The improved batteries would have a wide range of vehicle applications.

The University of Maryland (UMD) team seeks to fabricate fast-charging batteries in which the electrolyte comprises a cellulose fiber-based ion conductor. The cellulose-based ion conductor overcomes the gap from current solid-state electrolytes to solid-state batteries because they use natural materials, are easy to process, and are compatible with conventional coating processes. UMD’s approach could enable high conductivity at room temperature, high energy density, and roll-to-roll manufacturing of nano-paper batteries with low cost.

  • Pratt & Whitney. Hydrogen Steam Injected Intercooled Turbine Engine (HySIITE) - $3,822,026. Pratt & Whitney will design a novel, high-efficiency hydrogen-power turbomachine for commercial aviation. The Hydrogen Steam Injected Intercooled Turbine Engine (HySIITE) concept is intended to eliminate carbon emissions and significantly reduce NOx inflight emissions for commercial single-aisle aircraft. The HySIITE engine will burn hydrogen in a Brayton (thermodynamic) cycle engine and use steam injection to dramatically reduce NOx. Via an innovative semi-closed system architecture, HySIITE aims to achieve thermal efficiency greater than fuel cells and reduce total operating cost compared with “drop in” sustainable aviation fuels.

  • HRL Laboratories. Surface Laser Architected Magnets (SLAM) - $2,661,888. HRL Laboratories will develop novel magnets that improve the operating energy density of the state-of-the-art magnets for increased electric motor efficiency. Surface Laser Architected Magnets (SLAM) is a new magnet architecture that mitigates thermally induced demagnetization while reducing the use of expensive heavy rare earth elements. These magnets will increase motor efficiency, and thereby accelerate the adoption of electric ground and air vehicles, reduce energy demands and greenhouse gases, and reduce the need for non-domestic rare-earth elements.

Hinetics will develop and demonstrate a high-power density electric machine to enable electrified aircraft propulsion systems up to 10 MW and beyond. Hinetics’ technology uses a superconducting machine design that eliminates the need for cryogenic auxiliary systems yet maintains low total mass. The concept features a sub-20 K Stirling-cycle cooler integrated with a low-loss rotor, magnetic fields on an order of magnitude higher than conventional machines, and a novel coil suspension and torque transfer system with tensioned fibers that cut the cryogenic heat-load by a factor of 10 to eliminate the need for external coolers. This design could enable a 10 MW, 3000 RPM aircraft propulsion motor weighing less than 250 kilograms that rejects up to 10 times less total heat to the ambient environment (>99% efficiency).

A stunningly impressive and very long list of highly ambitious, disruptive, green and even cost-slashing research projects - but when will we finally see "other-worldly" propulsion technologies beyond rotating blades or rotating wheels of some kind - and I'm not referring to rocket-power. We hear so much talk now about frequent and highly credible military sightings of so-called "UAP's" - silent craft capable of incredible speed and manoeuvreability in the air and underwater. So are the likes of ARPA-e and Skunkworks exploring or perhaps even testing ultra-exotic forms of propulsion ?

A hydrogen steam-injected, inter-cooled, turbine engine with low carbon emissions and reduced NOx -- all in a closed system for a thermal efficiency greater than fuel cells.
How about also a hydrogen steam-injected, inter-cooled, internal combustion engine with low carbon emissions and reduced NOx -- all in a closed system for a thermal efficiency greater than fuel cells?
Why have we stopped developing the internal combustion engine without fully exploring its potential to also burn hydrogen-steam in a closed system?
