View Event Flyer
Description: This workshop convenes a global community across academia, national laboratories, international research institutions, and industry to identify challenges and opportunities in developing next-generation high-temperature particle heat transfer systems for process heat and thermal energy storage. Particle-based systems have been the subject of years of research, but require further advancement, including a push to higher temperatures, to transform thermal-industrial processes with a new generation of cost-effective heat delivery and storage. In this workshop, speakers will present the current state of challenges in analyzing and developing these systems, and present potential paths forward. Topics include modeling advances, integrated system models/technoeconomic analysis, experimental results, and operational experience from particle-based systems. In addition to presenting speakers, the audience will be invited to share ideas and suggestions for potential solutions and partnerships. Representatives from the U.S. Department of Energy (DOE) will participate to discuss portfolio projects and program priorities. The findings of this workshop will be reported to all conference attendees and DOE representatives to help create a shared vision of what is next for development of high-temperature particle-based heat delivery systems. The workshop will be 4 hours, including breaks.
The schedule is as follows:
1:00 - 2:15pm: Challenges in computational modeling, integrated system/technoeconomic models of high temperature particles
2:15 - 2:30pm: Break
2:30 - 3:45pm: Challenges in experimental measurements, and system operations for high temperature particles
3:45 - 4:00pm: Break
4:00 - 5:00pm: DOE research priorities and path forward planning
A detailed agenda will be provided before the start of the workshop. Drop-in-drop-out attendance is allowed. Attendees are encouraged to attend as many or as few presentations and discussions as they find relevant.
Cost: $25
