Enabling the broader adoption of fusion simulation on complex geometry

This project addressed a key barrier to advanced fusion and nuclear simulation: the difficulty of performing high-fidelity Monte Carlo neutronics directly on complex, real-world CAD geometry. Traditional workflows require engineers to rebuild CAD models as simplified constructive solid geometry, a time-consuming and error-prone process that limits design iteration and broader adoption of simulation tools. The goal of this Phase I SBIR was to make CAD-based neutronics practical, accessible, and robust for industrial and research users. During the project, Coreform significantly enhanced the Direct Accelerated Geometry Monte Carlo (DAGMC) workflow and fully integrated it into Coreform Cubit as a first-class capability. Major achievements include optimized material assignment and surface meshing workflows, substantial performance improvements to geometry imprinting and preparation, native export of DAGMC models, and new visualization tools to support OpenMC source definition and lost-particle debugging. Coreform also expanded Cubit’s capabilities as a full OpenMC preprocessor, including the ability to convert OpenMC constructive solid geometry models back into CAD for visualization, multiphysics coupling, and debugging. In collaboration with Argonne National Laboratory, the project delivered comprehensive new DAGMC documentation and training materials, transforming DAGMC from a research-oriented tool into a production-ready workflow. Results were disseminated through tutorials, conference training, and multiple well-attended webinars demonstrating integrated CAD-based neutronics and multiphysics workflows. Overall, this project demonstrated that high-fidelity Monte Carlo simulations can be performed directly on complex CAD geometry, reducing setup time, improving usability, and enabling faster, more informed design decisions for fusion and nuclear energy systems.

Real-Time Assessment of Robot Performance During Remote Exploration Operations

To ensure that robots are used effectively for exploration missions, it is important to assess their performance during operations. We are investigating the definition and computation of performance metrics for assessing remote robotic operations in real-time. Our approach is to monitor data streams from robots, compute performance metrics, and provide Web-based displays of these metrics for assessing robot performance during operations. We evaluated our approach for measuring robot performance with the K10 rovers from NASA Ames Research Center during a field test at Moses Lake Sand Dunes (WA) in June 2008. In this paper we present the results of evaluating our software for robot performance and discuss our conclusions from this evaluation for future robot operations.

An Investigation of Innovative Energy Technologies Entering the Market between 2009-2015, Enabled by EERE-Funded R&D

This report documents technologies that have been commercialized by the private sector and other partners—such as technology developers in startups, companies, and universities—in part because of R&D funding from EERE. It also documents emerging technologies that have the potential to reach the market within the next three years with the support of EERE R&D investments. Commercial and emerging technology tracking in this manner assists EERE technology managers, analysts, communications staff, and senior management in describing and explaining the benefits of EERE-funded research. Policy- and decision-makers would then have the latest information to guide future program development and direction.

Marine Energy Commercialization Review: Evaluation of the Transition From Public to Private Capital

The mission of the U.S. Department of Energy's Water Power Technologies Office (WPTO) is to advance marine energy technologies through research, testing, and commercialization. This paper explores the barriers and potential solutions for marine energy commercialization by evaluating publicly available literature, feedback from public and private actors, and historical WPTO actions. A key finding is the absence of standardized metrics to measure marine energy commercialization progress and the lack of targeted success goals. This paper aims to define those metrics, informed by public and private goals and the challenges developers experience, and to further evaluate targets offered by public funders and private capital providers. Recommendations to address barriers in marine energy commercialization include enhancing public-private communication, refining commercialization requirements, leveraging technology transfer programs, and exploring novel funding mechanisms like green bonds and contracts for difference. Addressing these challenges through proposed adjustments could facilitate the transition of marine energy technologies from public funding to sustainable private investment, ultimately advancing their commercialization.

Materials (FY 2022 Annual Progress Report)

This document summarizes the progress of VTO Materials R&D projects supported during the fiscal year 2022. The Propulsion Materials portfolio is closely aligned with other VTO subprograms to identify critical materials needs for next-generation high-efficiency powertrains for both heavy- and light-duty vehicles. The Lightweight Materials portfolio works closely with industry through the U.S. DRIVE Partnership to understand light-duty vehicle structural weight-reduction goals and identify technical challenges that prevent the deployment of lightweight materials.

S5: Information Technology for Science Missions

NASA Missions and Programs create a wealth of science data and information that are essential to understanding our earth, our solar system and the universe. Advancements in information technology will allow many people within and beyond the Agency to more effectively analyze and apply these data and information to create knowledge. The desired end result is to see that NASA data and science information are used to generate the maximum possible impact to the nation: to advance scientific knowledge and technological capabilities, to inspire and motivate the nation's students and teachers, and to engage and educate the public.

Power and Propulsion for Gateway: A NASA SBIR/STTR Success Story

NASA’s Gateway in lunar orbit will play a critical role in the Artemis program, which aims to land the first woman and the next man on the Moon by 2024. The development of the Power and Propulsion Element for Gateway is being led by Maxar Technologies, a mid-size organization, with contributions from two NASA SBIR/STTR awardees—Deployable Space Systems and Busek Company, Inc, both of which initially developed their Gateway contributions with support from the NASA SBIR/STTR program.

3-D Bioprinter Overcomes Gravity by Printing Living Tissues in Space

Techshot, Inc., based in Greensville, IN, is the first U.S. company to 3-D print organic products on the International Space Station (ISS). The company’s BioFabrication Facility (BFF), developed in collaboration with nScrypt, Inc., prints in space to overcome the effects of gravity on Earth, which cause 3-D printed tissues to disform under their own weight. Techshot’s BFF was launched to the ISS supported by the NASA SBIR/STTR program in 2019. The company has since worked with NASA and other customers, valuing BFF’s external investments at more than $5 million, including $2.5 million from the ISS Program.

Novel Lightweight Insulation Protects Fuel Tanks from Extreme Temperatures

Quest Thermal Group developed its integrated multi-layer insulation (IMLI) with funding from the NASA SBIR/STTR program. IMLI is high-performance insulation that protects spacecraft and cryogenic systems from extreme temperatures at a lighter weight than traditional MLI. IMLI performed successful flight demonstrations on NASA’s Robotic Refueling Mission 3 in 2018 and NASA’s Green Propellant Infusion Mission in partnership with large business Ball Aerospace in 2019, opening the door for additional opportunities with NASA and commercial customers.
