Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

Researchers from Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruher Institute of Technology in Germany have developed a novel energy conversion and storage system using seawater as a cathode. Similarly, sodium has recently attracted attention as a replacement for lithium in alkali-metal-air batteries.

Sandia progressing to demo stage with supercritical CO2 Brayton-cycle turbines; up to 50% increase in efficiency of thermal-to-electric conversion

Green Car Congress

—principal investigator Steve Wright of Sandia’s Advanced Nuclear Concepts group. Test results will illustrate the capability of the concept, particularly its compactness, efficiency and scalability to larger systems. The S-CO 2 system is also very compact, meaning that capital costs would be relatively low. Wright et al.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Our concept has the following advantages: Compared to carbon dioxide, solid bicarbonates are easy to handle and highly soluble in aqueous media (96 g L -1 NaHCO 3. Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle. at 20 °C in H 2 O).
