Greenhouse gas emissions, primarily from fossil fuel combustion, have surged, with energy-related processes releasing 41.3 gigatons of CO2 equivalents in 2022. The United Nations Climate Change Conference (COP28) highlighted the urgency to transition away from fossil fuels. Renewable energy has made progress, but heavy transport and industries face challenges. Carbon capture technologies like Power to X (PtX) and Carbon Capture and Utilization (CCU) offer solutions. Innovative chemical scrubbing methods are reducing energy costs, while integrated carbon capture and utilization (ICCU) technologies aim to convert CO2 into valuable compounds directly. Aarhus University's bio-integrated carbon capture and utilization (BICCU) technology uses microorganisms to absorb and transform CO2. The technology utilizes methanogenic microorganisms to convert CO2 into methane using renewable hydrogen. Challenges include the need for scalable and cost-effective electrolysis for hydrogen and managing oxygen in flue gases. Biological carbon capture offers a more cost-effective and sustainable solution compared to traditional methods. Expanding this technology to industrial flue gases could significantly aid in decarbonizing industries. As industries work towards net-zero emissions, carbon capture and utilization technologies play a crucial role in the sustainable transition to a greener future.
