Efficiency

University of Michigan will provide capability to measure hypothetical neutron, gamma, and ion emissions from LENR experiments. Modern instrumentation will be coupled with best practices in data acquisition, analysis, and understanding of backgrounds to interpret collected data and evaluate the proposed signal.

Phoenix Tailings’ CO2 GONE process uses and recycles CO2 to extract energy-relevant minerals, primarily nickel (Ni) and magnesium (Mg), from iron- and aluminum-rich ore through carbonation with CO2. Using CO2 with high pressures, temperatures, and mixing breaks down the rock structure and enables greater extraction of energy-relevant elements like Ni and Mg, which are then converted to metal carbonates (NiCO3, MgCO3).

Texas Tech University will develop accurate materials fabrication, characterization, and analysis to attempt to resolve the physical understanding of Low-Energy Nuclear Reactions (LENR). Texas Tech will also provide advanced detection of nuclear reaction products as a resource for ARPA-E LENR Exploratory Topic teams.

The University of Kentucky’s proposed technology will use CO₂ emitted at or near operating mines and processing operations to reduce the energy consumed during grinding by more than 50% while improving the recovery of critical energy relevant minerals by 20% or greater. In this approach, CO2 will be mixed with ore containing the valuable minerals, especially copper (Cu) and rare earth elements, to improve grinding and separation efficiency. Biological fixation of CO2 will also be studied and employed in producing acid to recover Cu from low grade feedstocks.

The University of Texas at Arlington will develop two technologies to produce lithium (Li) and nickel (Ni) from CO2-reactive minerals and rocks that contain calcium (Ca) and magnesium (Mg), while sequestering CO2 in the form of carbonate solids (calcium carbonate, or CaCO3; magnesium carbonate, or MgCO3; and variants thereof). The technologies, acoustic stimulation and electrolytic proton production, use electricity to liberate valuable metal ions from the surrounding mineral matrix at sub-boiling temperatures (~20-80°C).

The University of Texas, Austin, will conduct an in-situ injection of CO2 dissolved in water to permanently sequester CO2 via carbon-negative reactions (carbon mineralization), chemically fracture the rock via reaction-driven cracking before mining to reduce extraction and comminution energy by at least 50%, replace the CO2-reactive rock waste with carbonate to reduce energy needed for separation, improve concentrate grade, and increase ore recovery, and expand the lifespan of the mine as a CO2 sink once the ore is exhausted.

Stanford University will explore a technical solution based on LENR-active nanoparticles and gaseous deuterium. The team seeks to alleviate critical impediments to test the hypothesis that LENR-active sites in metal nanoparticles can be created through exposure to deuterium gas.

Energetics Technology Center will build upon past successes with co-deposition experiments using palladium, lithium, and heavy water together to create an environment in which LENR can occur. These electrolysis experiments decrease the distance from the cathode (location of LENR) to an electronic detector capable of detecting nuclear reaction products to give these experiments the best chance at reliably detecting nuclear reactions, if they are present.

Virginia Polytechnic Institute and State University (Virginia Tech) will develop an innovative carbon mineralization/metal extraction technology (CMME) that enables the recovery of energy-relevant elements during direct and indirect carbon mineralization processes. Virginia Tech will introduce an organic phase during the direct carbon mineralization process and in the mineral dissolution step of indirect carbon mineralization process. Energy-relevant elements are purified and separated through advanced separation technologies.

Boeing Research & Technology (BR&T) will develop a multidisciplinary topology optimization (MDTO) algorithm that couples fluid dynamics, heat transfer, and structural analysis to design, manufacture via additive manufacturing techniques, and demonstrate a high-performance, extreme environment heat exchanger (EEHX) capable of operating at up to 900°C with a 17 MPa pressure differential with supercritical carbon dioxide.
