GWU team suggests C2CNT carbon nanotube composites could amplify reduction of GHG emissions

Green Car Congress

Stuart Licht reports that the addition of carbon nanotubes (CNTs) produced from CO 2 by low-energy C2CNT (CO 2 to CNT) molten electrolysis ( earlier post ) to materials such as concrete or steel not only forms composites with significantly better properties, but amplifies the reduction of CO 2. A) Carbon mitigation with CNT-cement. (B)

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

AQDSH 2 refers to the reduced form of AQDS. The two main components—the electrochemical conversion hardware through which the fluids are flowed (which sets the peak power capacity) and the chemical storage tanks (which set the energy capacity)—may be independently sized. Cell schematic. Huskinson et al. Click to enlarge.

ARPA-E adds five new funding topics to FOA to advance critical energy innovation

Green Car Congress

Direct Removal of Carbon Dioxide from Oceanwater (DOC); $2.0 Direct Removal of Carbon Dioxide from Ambient Air (DAC); $2.0 Direct removal of CO 2 from the atmosphere, sometimes referred to as direct air capture (DAC), is the separation of CO 2 at ambient concentration (about 410 parts per million by volume fraction (ppmv)) from air.

Nitrogen-doped graphene nanoplatelets offer high catalytic performance in fuel cells and solar cells; possible replacement for Pt

Green Car Congress

Researchers in South Korea have developed a simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets (NGnPs) with excellent catalytic performance in both dye-sensitized solar cells and fuel cells to replace conventional platinum (Pt)-based catalysts for energy conversion. —Jeon et al.

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. mixture of hard carbon or Sn-C, SuperP carbon black as a conductive additive, and poly(vinylidene fluoride) as a binder.

Lloyd’s Register and UMAS release Zero Emission Vessels 2030 study

Green Car Congress

All analyses are performed against a heavy fuel oil (HFO) reference ship. For those in shipping with niche access to a low-cost supply of zero-emission fuel or energy sources, or an ability to pass on a voyage cost premium to a supply chain that values zero-emission services, the gap may already be closed.

IDTechEx calculates ~31 GWh of electric vehicle markets beyond cars in 2021

Green Car Congress

IDTechEx calculates that non-automotive EV sectors in 2021 demanded approximately 31 GWh globally in 2021; for reference, battery-electric and plug-in hybrid cars demanded approximately 280 GWh globally in 2021. Upcoming IMO policy includes an ‘Energy Efficiency Existing Ship Index (EEXI)’ and the Carbon Intensity Indicator (CII).
