Developing safe, effective, and orally available treatments for heavy metal poisoning (CRADA Final Report)

As part of the Cyclotron Road program, HOPO Therapeutics investigated the technical capabilities of heavy metal chelating agents for the sequestration, (re)distribution, delivery, and removal of metal ions, and their applications in the health, environment, and energy sectors. The project team researched chelating agents for use in the removal of heavy metals, and evaluated their potential benefits for a range of therapeutic, environmental, and energy applications.

Evaluation of Commercially Available Proprietary Vehicle-to-Home Systems: A V2X Connect Project Report

Bidirectional charging and Vehicle-to-Home (V2H) technologies enable the energy stored in a plug-in hybrid electric vehicle’s (PHEV) or battery electric vehicle’s (BEV) onboard battery to supply residential loads during grid outages and support broader energy management objectives. Conventional backup solutions, such as Uninterruptible Power Supplies (UPS) and standalone inverter systems, are limited in capacity and scalability, whereas PHEV/BEV-based storage offers substantially greater energy reserves that can sustain household loads for extended periods.

Navigating Economies of Scale and Multiples for Nuclear-Powered Data Centers and Other Applications with High Service Availability Needs

Nuclear energy is increasingly being considered for such targeted energy applications as data centers in light of their high capacity factors and low carbon emissions. This paper focuses on assessing the tradeoffs between economies of scale versus mass production to identify promising reactor sizes to meet data center demands. A framework is then built using the best cost estimates from the literature to identify ideal reactor power sizes for the needs of the given data center. Results should not be taken to be deterministic but highlight the variability of ideal reactor power output against the required demand. While certain advocates claim that with the gigawatts of clean, firm energy needed, large plants are ideal, others advocate for SMRs that can be deployed in large quantities and reap the benefits from learning effects. The findings of this study showcase that identifying the optimal size for a reactor is likely more nuanced and dependent on the application and its requirements. Overall, the study does show potential economic promise for coupling nuclear reactors to data centers and industrial heat applications under certain key conditions and assumptions.

Development of Readily Available & Robust High Heat Flux Gardon Gauges

Concentrated solar power (CSP) technologies deliver concentrated solar energy as a heat source to industrial processes, power generation cycles, and chemical cycles. CSP systems require accurate and reliable high flux measurements, and next generation CSP systems will require flux measurement up to 1000 W/cm2. Existing flux measurement devices do not comprehensively meet the flux rating, cycle life, cost, and lead-time needs of stakeholders, necessitating the development of an improved flux sensor. In this study, Sandia National Laboratories (SNL) partnered with Hukseflux Thermal Sensors to develop a low-cost, short lead-time, and robust flux sensor rated to 250 W/cm2. Three prototype circular foil gauge designs were assessed for performance at the National Solar Thermal Test Facility (NSTTF) at SNL. Each gauge design measured flux up to 250 W/cm2 with <5% measurement error. Following baseline error quantification, gauges were exposed to flux above 500 W/cm2 to assess gauge failure mechanisms. Gauges physically survived >500 W/cm2 flux exposure, but measurement error was found to increase after foil coatings reached 400 °C. The results of this study suggest that coating optical properties change at excessive temperatures and that foil coating temperature, rather than heat flux level, dictates the acceptable gauge measurement range.
