We’re still working on the 2025 agenda, but the 2024 agenda will give you an idea of what to expect. As well as speakers, THE HEAT 2024 featured a rich day of activities, including inspiring stories, expert workshops, product demonstrations, alt-food tastings, musical performances, art, 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!
Our schedule last year (2025 schedule still to be confirmed)
By invitation.
You’ll be guided through the festival, and will get to explore the festival campus, with climate-tech product demonstrations, future-food tastings, bespoke networking opportunities, and more.
A lively, informed, engaging and tightly curated session of 10-minute keynote talks, from key figures in climate-tech. Full details to follow in the coming weeks on our Speakers page.
Your ticket will include a lunch voucher, for a nutritious and tasty vegetarian picnic lunch. But we want you to make new friends, so we’ll redeem vouchers only when presented in groups of at least 4 (which means you’ll get to meet fellow THE HEAT participants!)
If you’d like to learn more about fusion, bring your picnic lunch to the main stage, where leaders of the industry will explain their approaches and take questions in this relaxed, informal session.
THE HEAT’s “unconference” sessions are driven entirely by you: over two hours, participants run sessions that they’ve proposed, including workshops, discussions, talks, science demos, or whatever you’re excited by. This is our “open-source” part of the day, tapping into the knowledge, creativity and thoughtfulness of the crowd. In the morning, you can propose your session with a marker pen on a whiteboard which is divided into 50-minute slots in 8 locations on the festival site. You can then pitch for an audience from the main stage before lunch. Surprise us!
You have a choice this hour: Be a dragon and evaluate five-minute pitches from 10 selected climate-tech startups that are currently fundraising. The VOYAGERS Climate-Tech Fund has pledged to invest up to £200,000 in the company that most impresses our team. OR Join us at the main stage for a bonus hour of keynote talks.
You’ll have a choice of workshops to participate in, led by VOYAGERS with specialist skills to share. There will also be speed-networking sessions, based on participants’ mutual interests (which we’ll collect in advance).
Participate in a Senegalese drumming circle, then enjoy a music set while you network that ranges from the VOYAGERS rock band, acoustic singers, to DJ sets . Do you want to perform? Tell david@voyagers.io
