Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

The resulting 12-sided carbon nanospheres had “bumpy” surfaces that demonstrated excellent electrical charge transfer capabilities. The resulting 12-sided carbon nanospheres had bumpy surfaces that demonstrated excellent electrical charge transfer capabilities. An open-access paper on the work is published in ACS Central Science.

MTU carbonate-superstructured solid fuel cell (CSSFC) delivers enhanced power density at lower operating temperatures

Green Car Congress

Now, researchers at Michigan Technological University have demonstrated a carbonate-superstructured solid fuel cell (CSSFC) in which in situ generation of superstructured carbonate in the porous samarium-doped ceria layer creates a unique electrolyte with ultrahigh ionic conductivity of 0.17 S⋅cm −1 at 550 °C. . … 2208750119

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

Cohort of new stakeholders joins Open Hydrogen Initiative

Green Car Congress

There is a high degree of variability in the carbon intensity of hydrogen production, even using the same technologies or pathways. The creation and adoption of these technical protocols will help build and harmonize the hydrogen market, contextualize climate solutions, advance transparency and support global trade in low-carbon hydrogen.

DOE to award up to $24M to advance direct air carbon capture technology

Green Car Congress

The US Department of Energy (DOE) will award up to $24 million for research into technology that captures carbon emissions directly from the air, replicating the way plants and trees absorb CO 2. ( DOE supports the search for carbon removal solutions at both the basic and applied science levels. DE-FOA-0002481 ).

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Our analysis assumes that captured carbon dioxide can be stored indefinitely, an optimistic and unproven assumption.
