Artificial Photosynthesis CO2 to Value

Detailed overview of innovation with sample startups and prominent university research


What it is

Artificial photosynthesis is a cutting-edge technology that aims to replicate the natural process of photosynthesis, using sunlight, water, and carbon dioxide (CO2) to produce valuable chemicals, fuels, and other materials. This innovative approach offers a potentially game-changing solution for addressing climate change by capturing and utilizing CO2 while simultaneously generating renewable energy.

Impact on climate action

Artificial Photosynthesis under the theme of C2V – CO2 to Value promises a significant impact on climate action. By mimicking natural photosynthesis to convert CO2 into valuable products like fuels or chemicals, it offers a sustainable solution to mitigate greenhouse gas emissions and foster a circular carbon economy, advancing global climate goals.

Underlying
Technology

Artificial photosynthesis involves mimicking the two key stages of natural photosynthesis:

  • Light Harvesting: Specialized materials, such as semiconductors or dye-sensitized solar cells, absorb sunlight and convert it into electrical energy.
  • CO2 Reduction: Catalysts, inspired by natural enzymes, utilize the electrical energy generated in the first stage to drive the reduction of CO2, converting it into various carbon-based products.
