The article discusses ways to reduce carbon emissions and produce clean energy. It focuses on using renewable resources like solar and wind power to create carbon-free hydrogen and bioenergy. One method involves using microalgae to capture and store carbon dioxide. By integrating bioenergy, carbon capture, and renewable energy, it is possible to significantly reduce emissions and move towards carbon neutrality. The research shows that these methods can produce large amounts of hydrogen and recover CO2. Innovative technologies like artificial photosynthesis and convective vortex systems are also explored for their potential in reducing carbon emissions.
