SUPER EARLY-BIRD TICKETS NOW ON SALE FOR NEXT YEAR’S FESTIVAL: SEPTEMBER 19 2025!

We’ve just released our first Super Early-Bird tickets for THE HEAT 2025. Tickets for THE HEAT will never be as cheap as today. Brought to you by the VOYAGERS Climate-Tech community, THE HEAT is a hands-on, practical, mind-expanding, friendship-building, exploratory, curiosity-led, science-based, creative, artistic, participatory, decentralised, experimental, edgy, live, risky, urgent and unpredictable gathering of 600+ talented people working on climate technologies.

THE HEAT is not a conference. Don’t expect dull panels or crappy coffee. Climate change is too urgent a problem to waste time. Instead, we designed it to help participants make new friends, to experience science in action, to learn and share their knowledge, to inspire and be inspired. Bring your most engaged and curious festival mindset. At THE HEAT 2024, festival-goers met nuclear-fusion startups, tasted future foods, witnessed carbon capture, experienced climate-robotics demonstrations… and enjoyed a climate-film festival, music performances and a startup pitch contest.

If you’re working in climate-tech, join us at Harwell Campus, near Oxford, on September 19 2025.

As well as speakers, THE HEAT 2024 featured a rich day of activities, including inspiring stories, expert workshops, product demonstrations, future-food tastings, musical performances, art installations, a participant-led “unconference”, tours of the Harwell Science Campus, a startup pitch competition, speed networking, an evening party — the hottest event on campus… and much more!
