    John Belizaire, CEO at Soluna: on Renewable-Powered AI, Curtailment & Building the Future of Sustainable Compute | Season Ten, Episode Nine

    Welcome to Season Ten of Conversations in Cleantech!   This season, we’re deconstructing digital infrastructure - one of the fastest-growing and most influential parts of the energy transition. From hyperscalers and AI demand to talent, capital, software and sustainability, we’ll explore how data infrastructure gets built, powered, financed, staffed and scaled. In this episode, Chloe England is joined by John Belizaire, Founder and CEO at Soluna - a company rethinking how AI infrastructure and renewable energy can work together. John shares the story behind Soluna’s model: co-locating modular data centres with renewable energy projects to utilise otherwise curtailed power behind the meter. By bringing compute directly to stranded renewable generation, Soluna is helping unlock new economics for clean energy while supporting the rapid growth of AI and digital infrastructure. The conversation explores grid congestion, renewable-powered compute, the growing energy demands of AI, and why data centres could become a catalyst for accelerating clean energy deployment rather than competing with it. John also reflects on his journey from Intel and multiple successful technology ventures to building Soluna, alongside his views on entrepreneurship, innovation, and the importance of diversity within the technology sector. As Season Ten comes to a close, this episode offers a fascinating look at one of the industry’s most ambitious intersections: the future of energy and the future of compute. 01:13 - Introduction to John 01:52 - You’ve had a fascinating journey from early renewables to building Soluna - what’s been the common thread driving your career? 05:11 - From your first startup to building Soluna, what’s the biggest lesson you carried forward into your later ventures? 07:40 - Was there a specific moment that led to the idea behind Soluna and pairing energy with compute? 13:08 - For those less familiar with the space, can you explain how Soluna pairs renewable energy with compute - and what’s happening behind the scenes? 20:30 - You’re not just building data centres, but an integrated energy and compute platform - is that how you think about Soluna internally? 25:43 - Are you primarily focused on the US market right now, or are you also expanding into Europe and other regions? 26:41 - Why has diversity been so important to you as a leader? 30:29 - How do you see Soluna evolving over the next few years, and what key milestones are you focused on?   Connect with your host, Chloe England, on LinkedIn.

    Sofie Käll, CIO and Anna Søndergaard, Co-Founder & CEO at The Footprint Firm: on Early-Stage Risk, System Innovation & Investing Beyond the Data Centre | Season Ten, Episode Five

    Welcome to Season Ten of Conversations in Cleantech! This season, we’re deconstructing digital infrastructure - one of the fastest-growing and most influential parts of the energy transition. From hyperscalers and AI demand to talent, capital, software and sustainability, we’ll explore how data infrastructure gets built, powered, financed, staffed and scaled. In this episode, hosts Jenny Gladman and Isabella Rova are joined by Sofie Käll, CIO, and Anna Søndergaard, Co-Founder, Partner & CEO at The Footprint Firm - two investors approaching digital infrastructure not from the centre of the asset, but from the edges of the system. As data centres place growing pressure on grids, water, cooling and materials, Sofie and Anna offer a different lens on what it means to invest in the future of digital infrastructure. Rather than backing the assets themselves, they focus on the technologies, services and efficiencies that can reshape the ecosystem around them - from grid balancing and energy storage to cooling innovation and software optimisation. This conversation explores what early-stage capital can realistically do in a market defined by speed, scale and physical constraint. It also digs into the balance between commercial viability and impact, the challenge of proving deep tech in real-world systems, and why some of the most meaningful opportunities may lie not in the “moonshots”, but in the less glamorous solutions that quietly improve performance at scale. For anyone curious about how venture thinking, systems change and sustainability intersect in the digital infrastructure buildout, this episode offers a sharp and refreshing perspective. 01:02 - Introduction to Sofie and Anna 02:45 - From an early-stage investor perspective, what makes the data centre ecosystem so compelling? 03:44 - Could you briefly introduce yourselves and share the story behind The Footprint Firm and the work you’re doing today? 07:31 - How do you approach digital infrastructure opportunities differently from traditional asset investors? 09:58 - How do you distinguish between incremental improvements and solutions that can truly scale commercially? 13:34 - How do you assess technical risk from a deep tech perspective? 18:14 - How do you see early-stage innovation helping address the growing energy demands of data centres? 21:47 - Do you see data centres acting as a stress test for broader energy transition technologies? 23:42 - Beyond power, where are the most under-discussed circular economy opportunities in the physical build of data centres? 27:00 - How do you connect the dots across sectors like energy, circular economy, and the built environment when investing in digital infrastructure - and who do you see as the winners? 32:25 - What drew you to this sector - was there a defining moment that shaped your decision to pursue it?
