Electric Field Enhancement of Solar Thermochemical Fuel Production
Background Solar thermochemical carbon dioxide (CO2) splitting is a process where solar energy is used to split CO2 into carbon monoxide (CO) and oxygen (O2). Conventional solar thermochemical CO2 splitting involves a metal oxide being heated to its reduction temperature using concentrated thermal energy, which liberates O2. This process also exposes...

Combining Air Capture and Water Splitting for Generating Carbon Dioxide and Hydrogen for Synthetic Fuel Production
Background The conversion of solar energy to fuels requires both water (H2O) and carbon dioxide (CO2) as feedstocks. These feedstocks provide the carbon and hydrogen atoms necessary to form hydrocarbons. By removing oxygen from one or both of these compounds, liquid hydrocarbon fuels can be produced. Water can be converted into hydrogen and oxygen...

Methods and Systems for Capturing and Concentrating CO2 Using Mesh Tubes
Background Carbon dioxide removal (CDR) from atmospheric air, which includes direct air capture (DAC), is essential to limit global warming to 2°C, or ideally 1.5°C. Current DAC methods based on thermal and pressure swings remain too energy intensive. Moisture-driven DAC using strong-base anion exchange resins (AER) binds CO2 from ambient air...
