Study finds high-density, low-rise cities such as Paris may be optimal urban form for reducing life cycle GHG emissions

Green Car Congress

A study by researchers at CU Boulder and Edinburgh Napier University finds that high-density, low-rise environments such as those found in Paris are the optimal urban form when looking to reduce greenhouse gas emissions over their whole life cycle. There is a growing belief that building taller and denser is better. —Francesco Pomponi.

Ecolectro secures $1.7M ARPA-E award for development of alkaline exchange membranes and ionomers for fuel cells and electrolyzers

Green Car Congress

Alkaline fuel cells (AFCs) that are assembled with alkaline anion exchange membranes (AAEMs) have several significant advantages in comparison to state-of-the-art proton exchange membrane fuel cells (PEMFCs). (1) 2) Oxidation of direct alcohol fuels (e.g., methanol and ethanol) is also significantly faster in AFCs. (3) Wei You, Kristina M.
