NACFE releases guidance report on hydrogen fuel cell heavy-duty trucks

Green Car Congress

Battery electric trucks should be the baseline for hydrogen fuel cells electric vehicle (HFCEV) comparisons, rather than any internal combustion engine alternative. Many factors will influence this, including emissions regulations, infrastructure, hydrogen availability and total costs of ownership. Stop comparisons of fill times.

2023 Hyundai Elantra N Review - Keeping The Faith

The Truth About Cars

We mourn the loss of cheap and cheerful pickup trucks. Call them, if you will, hot hatches, but any number of sporty, affordable, fun toys were once available from nearly any dealer. Cheap speed is only a pair of rose-tinted shades away. The black wing atop the trunklid looks a bit mild in comparison.

Jülich, ORNL researchers advance high energy density iron-air batteries

Green Car Congress

Iron–air batteries, originally proposed in the 1970s, have theoretical energy densities of more than 1,200 Wh/kg; by comparison, present-day lithium-ion batteries come in at about 600 Wh/kg, and even less (350 Wh/kg) if the weight of the cell casing is taken into account. —Weinrich et al.

Stanford researchers develop copper-based catalyst that produces ethanol from CO at room temperature; potential for closed-loop CO2-to-fuel process

Green Car Congress

However, efficient electrocatalysts for reducing CO 2 and its derivatives into a desirable fuel are not available at present. By comparison, conventional Cu nanoparticles with an average crystallite size similar to that of oxide-derived copper produced nearly exclusive H 2 (96% Faraday efficiency) under identical conditions.
