Sunlight to Fuel
Cheap devices turn sunlight, water and CO2 into liquid fuels and chemical feedstocks.
Open in the interactive tree →Liquid fuels store energy far more densely than batteries, which matters for aircraft and ships. A durable, inexpensive artificial photosynthesis would produce them without fossil carbon.
What it brings
- Climate-neutral fuel for aviation and shipping
- Energy storage over seasons in liquid form
- A carbon feedstock for the chemical industry without oil
