  2. Ørsted: Renewable Energy
    • A Danish multinational energy company that develops, constructs, and operates offshore and onshore wind farms, solar farms, energy storage facilities, renewable hydrogen, and green fuels facilities
  3. H2 Green Steel: Steel
    • Produce green steel in a fully integrated, digitalized, and circular plant in Boden, northern Sweden. They focus on reducing CO₂ emissions by up to 95% compared to traditional steelmaking by replacing coal with green hydrogen powered by fossil-free electricity
  4. Commonwealth Fusion Systems: Fusion Energy
    • CFS is working to design, build, and scale fusion power plants that will deliver cost-competitive, clean fusion energy to combat climate change. They focus on combining proven physics with revolutionary magnet technology.
  5. NuScale: Nuclear Energy
    • Designs and markets [small modular reactors (SMRs)](<https://www.world-nuclear.org/information-library/nuclear-fuel-cycle/nuclear-power-reactors/small-nuclear-power-reactors.aspx) that can replace retiring coal plants and provide reliable baseload powers for wind and solar.
  6. BYD: Electric Vehicles
    • Build Your Dreams is an industry leader in electronics, automotives, renewable energy, and rail transit. They're on track to be the world's biggest seller of EV cars.
  7. GEM: Battery Recycling
    • Green Eco-Manufacture, is a leading company in battery recycling, focusing on processing electronic waste and retired electric vehicle batteries. They use versatile factories and hydrometallurgical extraction techniques to effectively remove critical materials from used batteries
  8. Climeworks: Carbon Removal
    • Swiss company that develops and operates direct air capture (DAC) technology to remove CO₂ from the atmosphere. Their modular DAC plants capture CO₂ from ambient air, which can then be stored underground or used in various industries
  9. ReNew: Renewable Energy
    • India's largest renewable energy company by operational capacity, they develop, build, and operate utility-scale wind and solar energy projects. They focus on providing decarbonization solutions to help combat climate change and promote sustainable development
  10. NotCo: Food and Agriculture
    • A food technology company that uses Artificial Intelligence to create plant-based alternatives to animal-based products. They process and learn infinite combinations of plants, and store an huge amount of information (physicochemical, molecular, nutritional) to replicate animal products.
  11. Twelve: Chemicals
    • Transforming CO₂ emissions into valuable chemicals and materials like industrial photosynthesis. They use electrochemical processes to convert CO₂ into essential products, such as ethylene, propylene, and other chemicals, helping to reduce greenhouse gas emissions and promote a circular economy
  12. Form Energy: Energy Storage
    • Developing long-duration energy storage systems to enable a reliable and affordable transition to a renewable energy grid. Their technology aims to store energy for days or even weeks, addressing the intermittency challenges of renewable energy sources
  13. Gogoro: Electric Vehicles
    • Gogoro is a Taiwanese company that designs and manufactures electric scooters and battery-swapping infrastructure. They focus on providing sustainable urban transportation solutions through their smart electric scooters and energy network
  14. Sublime Systems: Cement
    • Develops innovative technologies to reduce CO₂ emissions in the cement industry. They use an electrochemical process to create low-carbon cement, avoiding the emissions from combustion for heating and decomposition.
  15. Blue Frontier: Air Conditioning
    • Developing energy-efficient and environmentally friendly air conditioning systems. They aim to reduce the energy consumption and greenhouse gas emissions associated with traditional air conditioning technologies
