Problem
The continued reliance on fossil fuels for energy, transportation, and chemical production contributes significantly to CO₂ emissions, driving climate change and necessitating the development of sustainable alternatives. Existing methods for producing sustainable fuels and chemicals often struggle to achieve price parity with fossil fuels, hindering widespread adoption.
Solution
Liquid Sun offers a low-temperature electrolysis (LTE) technology that converts CO₂ and water into valuable e-fuel feedstocks and e-chemicals using renewable electricity. This process, inspired by artificial photosynthesis, recodes carbon emissions into sustainable hydrocarbons, providing a cost-effective alternative to fossil fuels. The LTE technology utilizes innovative catalyst materials and electrolyzer designs to enable selective chemical production, offering flexibility in the end-products, including carbon monoxide, ethene, and formic acid. Liquid Sun's solution integrates with existing infrastructures, supplying synthetic hydrocarbons to the energy, transportation, and chemical sectors, reducing carbon footprints and creating additional revenue streams for facilities.
Target Audience
Liquid Sun's primary customers include companies in the aviation, chemical, energy, transportation, and shipping industries seeking sustainable alternatives to fossil fuels and methods to reduce their carbon footprint.
