Colorado Teardrops developing EV-specific teardrop trailer: The Boulder

Green Car Congress

The Boulder has a 75 kWh battery pack built into the trailer frame to recharge the EV’s batteries. As a comparison, the company’s conventional Mt. EV drivers can recharge their car’s battery pack using the batteries in the Boulder. Colorad teardrops envisions a line of future EV-specific trailers.

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

Researchers from Japan’s NIMS (National Institute for Materials Science), the University of Tokyo and Hiroshima University have jointly conducted a techno-economic analysis for hydrogen production from photovoltaic power generation (PV) utilizing a battery-assisted electrolyzer. This approximately converts to US$1.92 to US$3.00/kg to US$3.00/kg

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

Green Car Congress

Then the team tested the material’s electrical performance as the anode, with lithium metal as the cathode, inside a coin-shaped battery. (a) In comparison, lithium-ion batteries made with other carbon-based anodes, including graphite and carbon nanotubes, held almost no charge at freezing temperatures. C and maintained 85.9%

TU Berlin team develops multifunctional catalyst for ORR and OER for fuel cells or rechargeable metal-air batteries

Green Car Congress

One of the challenges in electrocatalysis (be it for solar fuels, fuel cells or rechargeable metal-air batteries) is to find an effective catalyst that will reduce (oxygen reduction reaction, ORR), as well as generate (oxygen evolution reaction, OER), oxygen at moderate temperatures.
