THE HEAT is a hands-on climate-tech festival celebrating innovation that’s good for the planet. Held at Harwell Science Campus near Oxford, the event brings together founders, researchers, investors, institutional partners and practitioners for product demonstrations, workshops, future-food tastings, short talks, an unconference and music — designed to spark collaboration, learning and rapid climate action.

The festival is experiential rather than a traditional conference: expect demonstrations of climate technologies (from carbon capture to fusion startups), participatory exhibits, networking and curated conversations for a high-impact community of 600+ attendees.

THE HEAT is produced by VOYAGERS, a global community of impact-driven people that runs specialist climate-tech and health-tech groups, not-for-profit weekend adventures, workshops, co-working retreats and community investment funds. VOYAGERS aims to build deep friendships, peer support and practical collaborations that accelerate mission-driven innovation.

Headquartered in London, VOYAGERS organises festivals and programmes to connect entrepreneurs, scientists, investors and ecosystem builders around real-world solutions to urgent problems including the climate crisis.
