Engineered for Impact, with Christian Garcia (Partner at Breakthrough Energy Ventures)

This week on Valley of Depth, we’re joined by Christian Garcia, Partner at Breakthrough Energy Ventures — the Bill Gates-backed climate fund investing in bold technologies to accelerate the energy transition across every sector of the economy. With portfolio companies tackling everything from geologic hydrogen to reusable rockets, BEV is redefining what it means to scale climate impact through hard tech. In this conversation, Christian shares how BEV thinks about breakthrough innovation, what makes a venture-backable climate solution, and why some of the most disruptive ideas look impossible—until they’re not. We also get into:BEV’s origin storyHow climate and national security are convergingThe firm’s approach to fusion, hydrogen, and aerospaceWhy BEV backed both CFS and Pacific FusionWhat drew Christian to space — and Stoke Space in particularAnd his take on what’s really being underestimated in climate today• Chapters •0:00 - Intro1:04 - What is Breakthrough Energy Ventures and how is it different from a typical fund?2:26 - BEV's investors and why are they interested5:45 - Is there a defense interest at BEV?9:00 - How did Christian get into this space?11:13 - What is BEV currently focused on?14:17 - What type of breakthrough is BEV investing in and when?17:16 - Firms BEV co-invests with18:34 - Seed and Pre-seed investing25:43 - What is the goal of investing in multiple fusion companies?30:23 - How does space fit in BEV's climate portfolio?34:23 - How do you separate bold vision from wishful thinking?38:03 - Balancing science and storytelling42:08 - Tech that Christian has passed on45:37 - A BEV company that Christian thinks will shock the world with its success48:48 - What are some common misconceptions about climate tech?51:28 - Rapidfire questions • Show notes •BEV’s website — https://www.breakthroughenergy.org/our-work/breakthrough-energy-ventures/BEV’s socials — https://x.com/BreakthroughMo's socials — https://twitter.com/itsmoislamPayload’s socials — https://twitter.com/payloadspace / https://www.linkedin.com/company/payloadspaceIgnition’s socials — https://twitter.com/ignitionnuclear /  https://www.linkedin.com/company/ignition-nuclear/Tectonic’s socials  — https://twitter.com/tectonicdefense / https://www.linkedin.com/company/tectonicdefense/Valley of Depth archive — Listen: https://pod.payloadspace.com/ • About us •Valley of Depth is a podcast about the technologies that matter — and the people building them.
