Efficiency

The technology proposed by the Georgia Institute of Technology avoids surfactant use to generate a stable foam by instead relying on hydrodynamic means to generate an unstable high-density foam to disperse the fiber into. The fiber mat is formed in a fast dynamic process before loss of integrity of the multi-phase fiber-air bubble mixture. The team will develop a next-generation paper manufacturing system that includes a novel microbubble generator integrated with a next generation headbox that can scale up for commercial production.

Captura will demonstrate efficient CO2 stripping from oceanwater using low-cost thin film composite hollow fiber membranes. The team will use ultra-low-cost hollow fiber membranes, traditionally used in water filtration applications, as a structural support, and modify their outer layers with highly CO2 permeable polydimethylsiloxane layers to selectively strip CO2 from oceanwater. Captura will also employ a computational model-assisted design and rapidly prototype new gas liquid contactor designs that use counterflow and cross-flow design for efficient CO2 stripping from oceanwater.

Gencores enables technology for ultra-light vehicles to decarbonize transportation. Herein they demonstrate a scalable and digital production of low-cost and high-performance hybrid Polymethacrylimide (PMI) foam cores for sandwich composite constructions. Sandwich composites feature a foam core wrapped in fiber-reinforced skins and offer a 40-75% weight reduction potential compared with traditional metal alternatives. Current PMI foam cores are costly and time-consuming to produce in complex shapes.

The University of Tennessee-Knoxville (UTK) will develop higher performance, carbon-negative, and eco-friendly lignin polyurethane (PU) foams as a building insulation material via non-isocyanate synthesis. Non-isocyanate PU via polyaddition of cyclic carbonates and amines is non-toxic and non-moisture sensitive. Lignin is inherently hydrophobic, antibacterial, and fire-resistant, which are essential properties of insulation materials. Lignin’s propensity to char instead of ignite is advantageous but insufficient to address modern anti-flammability requirements.

Metalx Biocycle aims to enable the recycling of critical metals from electronic waste (e-waste) at a cost that is competitive against extraction via conventional mining. Most e-waste ends up in landfills where it causes serious environmental issues; and conventional extraction methods rely on inefficient, expensive, energyintensive processes. The Metalx Biocycle team will leverage biological processes to efficiently extract, concentrate, and purify critical metals and rare earth elements from e-waste and low-grade mineral ores.

The Makai Ocean Engineering team will develop novel mooring and anchoring methods to reduce the costs of offshore renewable energy. Makai will enable grid-scale FOWT and MHK systems to be deployed in areas that would otherwise be inaccessible or too expensive with current mooring and anchoring technologies. At the center of this program is Makai’s Remote Anchoring and MicroPiling (RAMP) system, which can remotely install micropiles on the seafloor.

The University of Michigan and Southwest Research Institute will use state-of-the-art methods to eliminate methane emissions from oil and gas (O&G) flares, vents, and other equipment. The approach will quantitatively characterize high- and low-volume methane sources at an actual O&G field site and demonstrate Systems of Advanced Burners for Reduction of Emissions (SABRE) technology for high-efficiency (> 99.5%) methane conversion of the high- and low-volume sources of methane. The SABRE approach leverages site resources and customizes flare technology to local equipment needs.

Texas Tech will develop boron nitride (BN) fast neutron detectors (FND) for energies up to tens of mega-electron volts based on their recent development of hexagonal BN semiconductor thermal neutron detectors with record efficiencies of >59%. BN FNDs have unique advantages, including compact size, high gamma rejection ratio, low voltage operation, and low fabrication and maintenance costs. These neutron detectors can operate in high temperatures and harsh environments and detect thermal and fast neutrons simultaneously.

AtmosZero, in partnership with Colorado State University, seeks to develop a modular high-temperature heat pump system with the potential to significantly reduce carbon emissions from on-site heat generation in the U.S. industrial sector. Approximately 75% of all on-site energy consumption in the U.S. manufacturing sector is used to generate heat, which means industrial process heat must be decarbonized to substantially reduce U.S. emissions.

Media and Process Technology (MPT) proposed a process to convert high-energy evaporative drying into lowenergy filtration with the potential to reduce energy consumption in wet substrate dewatering by up to 90%. The team will demonstrate the technical feasibility and energy and cost savings potential of a non-evaporative substrate drying process based upon supercritical CO2 (scCO2) extraction combined with downstream ceramic membrane filtration.
