    Advanced Nuclear Technologies Leading to New Interest

    Panel Hydrogen/Clean Tech & Power Innovation & Technology

    Nuclear technologies are attracting a resurging interest as global net-zero targets reveal gaps in clean resource adequacy, necessitating development of a clean reservoir infrastructure. This panel will explore the pathways and hurdles for advanced nuclear to become the clean base-load option of choice in the next phase of the energy transition. What technological advances have been made since the build-out of the legacy fleet to accommodate heightened needs for resilience and flexibility? How does advanced nuclear stack up against peer technologies in the clean reservoir space such as batteries and hydrogen? Will we see head-to-head competition for market share or are there opportunities to harmonize?
