     Innovating technologies to capture CO₂‚ emissions from industrial sources and the atmosphere.
Carbon Capture, Utilization, and Storage (CCUS) is a technology aimed at reducing carbon dioxide (CO₂) emissions from industrial sources by capturing and storing or repurposing it instead of releasing it into the atmosphere. The process begins with capturing CO₂ from sources like power plants, cement factories, and chemical industries, which are major contributors to greenhouse gas emissions. Once captured, the CO₂ can either be transported to storage sites, typically underground in geological formations, or used in various industrial applications. Utilizing CO₂ in products like building materials, fuels, and even certain chemicals provides a way to create value from captured emissions, contributing to a circular economy.
Storing CO₂ underground in depleted oil and gas reservoirs or deep saline formations prevents it from entering the atmosphere, effectively reducing emissions. CCUS is viewed as an important bridge technology, especially for industries that are difficult to decarbonize, as it allows them to operate while working towards low-carbon alternatives. The technology is also seen as complementary to renewable energy, helping to stabilize emissions in the transition to a cleaner energy system. However, CCUS faces challenges, including high costs, energy requirements for capture and transportation, and the need for robust monitoring systems to ensure CO₂ remains stored securely. Despite these challenges, CCUS is gaining traction as countries aim to meet climate targets, with increased investment and research making it a viable part of global climate strategy.
