Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. The conversion rate reaches 32.9 ± 1.38 —Song et al. Song et al. 2301206120

MIT researchers boost efficiency of carbon capture and conversion systems

Green Car Congress

Researchers at MIT have developed a method that could significantly boost the performance of carbon capture and conversion systems that use catalytic surfaces to enhance the rates of carbon-sequestering electrochemical reactions. The movement through water is sluggish, which slows the rate of conversion of the carbon dioxide.

University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.
