Goodenough perspective on Li-ion batteries; in transportation, PHEVs for the near-term, longer term requires new electrochemical strategies

Green Car Congress

John Goodenough at the University of Texas at Austin and colleague Kyu-Sung Park have written a perspective paper on Li-ion batteries (LIBs), published in the Journal of the American Chemical Society. Opportunities exist for the chemist to bring together oxide and polymer or graphene chemistry in imaginative morphologies. ”.a

Starfire Energy closes major funding round; green ammonia and hydrogen solutions

Green Car Congress

Ammonia offers an energy density comparable to fossil fuels and significantly higher than Li-ion batteries and compressed or liquid hydrogen. It can be stored and transported inexpensively and easily, leveraging established infrastructure and shipping networks, and is regulated by well-developed codes and standards.

Five Cool Tech Demos From the ARPA-E Summit

Cars That Think

Gas Li-ion batteries thwart extreme cold South 8 Technologies demonstrates the cold tolerance of its Li-ion battery by burying it in ice at the 2024 ARPA-E Energy Innovation Summit. That’s a big improvement on conventional Li-ion batteries, which start to degrade when temps reach 0 °C and shut down at about –20 °C.

Valence Signs Multi-Year Li-ion Supply Agreement with Bénéteau Group for Hybrid Vessels

Green Car Congress

New hybrid-electric sea-going vessels yield low to zero-emissions, reduce fuel consumption and require less maintenance than traditional diesel marine propulsion systems. The ZF Marine hybrid drive system creates kinetic energy when reversing the propeller while under sail, thereby storing this regenerative energy back into the batteries.

ERTRAC publishes roadmap on energy carriers and powertrains; role for power-to-gas

Green Car Congress

For the topic of future road mobility these are the development of alternative and decarbonized fuels and energy carriers; and higher powertrain efficiency leading to cleaner mobility and reduction in resource demand. Liquid Air technically does not store any energy, as energy has been removed to create it. Liquid Air. Earlier post.)
