Abstract In response to the urgent need for innovative solutions to global climate change, this project introduces a solar-driven carbon-fixation moss bioreactor, aimed at converting atmospheric carbon dioxide into valuable products. Traditional carbon dioxide supply methods, such as pressurized aeration, are energy-intensive. To address this, we propose a two-stage bioreactor process. Initially, moss biomass is increased through pre-cultivation. Then, an innovative gas-phase bioreactor facilitates direct moss contact with the gaseous substrate, significantly enhancing carbon dioxide bioconversion efficiency and energy conservation. Unique to our approach is the use of moss as a biofixer, chosen for its adaptability and high chlorophyll content, making it a superior candidate for carbon sequestration compared to common microalgae and bacteria. Furthermore, the integration of the bioreactor with a solar system ensures optimal use of sunlight, converting unused wavelengths into electricity. This integration not only generates power but also supports the bioreactor′s operational needs, promoting efficient moss growth and improved carbon fixation.
