As 2025 approaches, the climate tech landscape is shifting, influenced by recent U.S. federal election outcomes that may jeopardize the Inflation Reduction Act. Despite challenges, there is a growing interest in nuclear, fusion, and hydrogen technologies to meet soaring energy demands from AI data centers. Startups are exploring smaller nuclear designs and advancing fusion projects, while hydrogen firms face uncertainty due to potential subsidy cuts. The year ahead could be crucial for investment and innovation in these sectors, as companies navigate regulatory changes and funding opportunities.
