Carmichael Roberts uniquely operates as both co-founder of the specialized Material Impact Fund and a leader at Bill Gates's Breakthrough Energy Ventures, combining roles that span early materials-focused venture formation and large-scale climate capital deployment. His background as a bioorganic chemist who became a serial materials entrepreneur before investing gives him an unusually deep technical foundation for evaluating hard-tech startups, particularly those focused on making energy and infrastructure systems more resilient.

• Targeting carbon capture and removal technologies. The core message is that actively pulling greenhouse gases from the atmosphere is just as essential for reaching net-zero emissions as reducing new output. For example, celebrating Sustaera raising funds for its low-cost direct air capture system and Pachama using technology to scale reforestation efforts.
• Investing in the electrification of transportation and advanced battery technology. The emphasis is that eliminating fossil fuels requires transforming everything from maritime logistics to aviation, supported by resilient supply chains. An example is the investment in Fleetzero to electrify ocean cargo shipping, as well as praising Our Next Energy for achieving an unprecedented 750-mile range on a single electric vehicle battery prototype.
• Transforming heavy industry and legacy physical infrastructure. The underlying point is that tackling the climate crisis requires reinventing how we construct everyday materials and manage industrial waste, which are major hidden polluters. A standout example is highlighting Brimstone for developing a novel method to completely eliminate carbon dioxide emissions from the traditional cement manufacturing process.
• Championing deep scientific breakthroughs over simple software applications. The overarching belief is that the best engineering talent is currently migrating from traditional tech hubs toward solving complex physical problems. This is heavily reflected in the enthusiastic backing of Commonwealth Fusion Systems and their record-breaking magnet tests designed to bring commercial fusion power to the grid within the next decade.
