Brimstone is a developer of a novel process intended to produce carbon-negative Portland cement and supplementary cementitious materials. The company provides a cost-effective process for converting waste sulfur into green hydrogen and sulfuric acid, enabling users to replace conventional processes with a cost-effective and clean electrochemical system.
CarbonCure manufactures a carbon dioxide (CO₂) utilization technology that introduces captured CO₂ into fresh concrete to reduce its carbon footprint. Once injected, the CO₂ undergoes a mineralization process and becomes permanently embedded. This results in economic and climate benefits for concrete producers—truly a win-win. CarbonCure’s innovative carbon removal technology is a direct way to reduce embodied carbon, or the carbon footprint of the manufacturing and transportation of building materials. The technology is retrofitted into concrete plants without disrupting operations and seamlessly integrates with existing batching processes. With CarbonCure, architects, engineers, contractors, developers and building owners have an easy way to reduce embodied carbon without making compromises. Building with concrete made with CarbonCure reduces CO₂ by an average of 15 kilograms per cubic metre (25 pounds per cubic yard).
Hippo Harvest is a CEA startup developing greenhouse systems that are cost competitive with fields. We use passive hydroponic methods, robotics, and machine learning as tools to keep capex low, increase productivity, and achieve faster learning cycles relative to today's CEA methods. We aim to transition fresh produce to a more sustainable future.
Infinium offers an industry leading, commercial ready electrofuels solution that can decarbonize the transportation industry today using existing infrastructure. Produced using renewable power and CO2 emissions, Infinium’s Electrofuels™ can be used by existing truck, plane and ship fleets, enabling immediate decarbonization of the transportation sector. Electrofuels are exactly what they sound like: fuels made from electricity instead of oil. Infinium facilities utilize low-cost renewable energy sources and prevent excess clean energy from going to waste. Using CO2 and green hydrogen (produced through renewable powered electrolysis) as feedstocks, its facilities remove CO2 from industrial emissions and provide a ready use for growing hydrogen production.
