Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. Earlier post.) —Licht et al.

In the Solar Thermal Electrochemical Process (STEP), developed by Professor Stuart Licht and his group at GWU, solar UV–visible energy is focused on a photovoltaic device that generates the electricity to drive the electrolysis, while concurrently the solar thermal energy is focused on a second system to generate heat for the electrolysis cell.

For the current study, Toma and her team designed a model solar fuels device known as a photoelectrochemical (PEC) cell made of copper(I) oxide or cuprous oxide (Cu 2 O), a promising artificial photosynthesis material. We knew it was unstable—but we were surprised to learn just how unstable it really is. —Francesca Toma.

One way to circumvent both problems is to link man-made solar cells to biological CO 2 fixation and fuel production. Theoretically, H 2 generated by solar electricity can drive CO 2 fixation in lithoautotrophic microorganisms engineered to synthesize high energy-density liquid fuels. —Li et al. Han Li, Paul H.

kWh/kg—about 20 times the specific energy of advanced Li-ion batteries with silicon anodes. Renewable energy sources such as wind or solar power plants generate excess current at times when it is not needed. It offers energy densities of 4.4 kWh/l—almost six times that of hydrogen—and 5.5 kWh battery.
