(5)Chris Holmes
Chris Holmes is the President and CEO of AvCarb Material Solutions, a Lowell, Massachusetts maker of engineered carbon materials - the felts, fabrics, and papers that quietly sit at the heart of hydrogen fuel cells, electrolyzers, and flow batteries. An MIT-trained systems engineer with a hybrid technical-and-business background, he is a turnaround specialist who has led high-technology businesses from start-up scale to north of $200M in revenue, largely inside private-equity portfolios. At AvCarb he is steering a company with 1960s roots toward the center of the clean-energy transition.
Joshuah Stolaroff
Joshuah Stolaroff is the co-founder and CEO of Mote, a Los Angeles clean energy company turning woody waste into renewable hydrogen while permanently burying the carbon. A Carnegie Mellon-trained engineer who built one of the first working prototypes for pulling CO2 straight out of the air, he spent eleven years running the carbon capture program at Lawrence Livermore National Laboratory before co-authoring 'Getting to Neutral,' the report that launched the Biomass Carbon Removal and Storage (BiCRS) approach now at the heart of Mote. His aim is blunt: reduce and remove a billion tons of carbon by 2035.
Parker Meeks
Parker Meeks is the President and CEO of Utility Global, a Houston-based clean-energy company commercializing H2Gen, a system that makes low-cost clean hydrogen on-site from industrial waste gases without electrolysis. A Houston native and electrical engineer turned McKinsey partner, he previously led hydrogen fuel-cell maker Hyzon as CEO. At Utility he is steering the company from demonstration into global commercialization, including a first commercial-scale steel project with ArcelorMittal in Brazil.
Siva Yellamraju
Siva Yellamraju is the co-founder and CEO of Fourier, a Palo Alto hydrogen startup building modular, software-controlled electrolyzers no bigger than two server racks. A four-time founder whose previous companies were acquired by Apple, Google, and Polycom, he spent a career in cameras and video before turning a 10-15% side exploration into a clean-energy company. Fourier treats hydrogen production as a data-optimization problem, aiming to deliver on-site hydrogen at $6-7/kg. The company raised an $18.5M Series A led by General Catalyst and Paramark Ventures in April 2025.
Ted McKlveen
Ted McKlveen is the Co-Founder and CEO of Verne, a San Francisco-based clean energy company pioneering cryo-compressed hydrogen (CcH2) technology to decarbonize heavy-duty transportation and off-grid power. He graduated summa cum laude in Chemistry from Harvard and earned an MBA from Stanford GSB (2021), where he co-founded Verne. Under his leadership, Verne unveiled the world's first CcH2 Class 8 heavy-duty truck, secured backing from Amazon's Climate Pledge Fund and United Airlines Ventures, raised $15.5M total, and expanded into a new Pennsylvania manufacturing facility creating 61 jobs.
