We've noted for you that there exist some globally-organized groups focused on the development of artificial photosynthesis technology for the solar light-driven and productive chemical utilization of Carbon Dioxide.
Not well-publicized is the fact that our USDOE has been an active participant in those international groups, as can be learned via:
Solar Energy Innovation | Solar Fuels Instiute; "The SOFI team dreams big. We believe the development of a carbon neutral solar fuel is the greatest energy opportunity of our lifetime. Using just sunlight, carbon dioxide, and water, we can create a clean liquid fuel that could someday power our cars, airplanes, and homes without contributing to climate change"; and:
