The innovation lies in the exploitation of novel natural energy source: reduced metal deposits. The energy released during oxidation of these metals could be used to reduce CO2 into fuels and chemicals reducing petroleum usage.This proposed project fits within the Chemical-Chemical Area of Interest, as it involves the coupling of the oxidation of reduced minerals in the Earth’s crust to the production of reduced carbon chemicals for fuel utilization.

Utah State University (USU) will develop a technoeconomic analysis to assess the feasibility and environmental and economic impacts of various electric roadway technologies. This project will aggregate, synthesize, and link previously isolated data sets to form a high-resolution, comprehensive assessment of electric roadways at the regional scale. Localized grid and road construction cost estimates are being considered.

The University of Maryland (UMD) will develop an electrochemical compression technology for ammonia. Electrochemical (an alternative to mechanical) compression has rarely been considered for ammonia, and the UMD team seeks to develop a new method to raise the compression efficiency from its current rate of 65% to the long term goal of up to 90%.

Tetramer Technologies will develop an anion exchange membrane (AEM) as an alternative to proton exchange membranes (PEM) for use in fuel cells and electrolyzers. The team will test a newly developed AEM for stability in alkaline conditions at a temperature of 80°C, enhanced ion conductivity, controlled membrane swelling, and other required properties. Industry has not yet achieved a cost-effective, commercially viable AEM with long-term chemical and physical stability.

Purdue University will develop new bio-inspired ultrahigh strength-to-weight ratio materials. To do so, they will develop porous metal replicas of diatom frustules, which are hollow silica (glass) structures that have evolved over millions of years to possess high resistance to being crushed by predators. They are targeting structures possessing high strengths (> 350 MPa or 50,763 PSI) and low densities (<1000 kg/m3), which they will evaluate using microscale mechanical tests and simulations.

Lawrence Berkeley National Laboratory (LBNL) will develop a high power density, rapid-start, metal-supported solid oxide fuel cell (MS-SOFC), as part of a fuel cell hybrid vehicle system that would use liquid bio-ethanol fuel. In this concept, the SOFC would accept hydrogen fuel derived from on-board processing of the bio-ethanol and air, producing electricity to charge an on-board battery and operate the motor.

Harvard University will develop new methods to harness naturally occurring microbial communities for the biological production of ethane and propane. Strong indirect evidence suggests that ethane and propane are produced in the ocean by communities of benthic microorganisms in unique deep-sea sediments under specific conditions. The team will target the microbial communities in the ethane- and propane-rich hydrothermal sediments of the Guaymas Basin in the Gulf of California.

The team at the California Institute of Technology (Caltech) has developed a method to determine the mechanical properties of lithium as a function of size, temperature, and microstructure. The body of scientific knowledge on these properties and the way dendrites form and grow is very limited, in part due to the reactivity of metallic lithium with components of air such as water and carbon dioxide. The team proposes to conduct a targeted investigation on the properties of electrodeposited lithium metal in commercial thin-film solid-state batteries.

Johns Hopkins University will study the adsorption compression phenomenon for ways to enhance the reaction rate for commercially relevant reactions. Adsorption is the adhesion of molecules from a gas, liquid, or dissolved solid to a surface, creating layers of the “adsorbate” on the surface of the host material. The Johns Hopkins team will explore the physical state where the forces acting parallel to the surface of adsorbate molecules can in certain conditions be far higher than forces associated with adsorption of additional molecules on the surface.

Georgia Tech Research Corporation will develop hollow fiber membranes containing metal-organic framework (MOF) thin films to separate propylene from propane. The nanoporous MOF film is supported on the inside surfaces of the tubular polymeric hollow fibers. Chemicals introduced into the center of the tube are separated through the MOF membrane by a molecular sieving process. Traditional olefin production processes are performed at pressures up to 20 bar, requiring large energy and capital costs.
