Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

The study considers five different powertrains (internal combustion engine, hybrid-electric, plug-in hybrid-electric, fuel-cell-electric, and battery-electric) and 12 cost components (purchase cost, depreciation, financing, fuel, insurance, maintenance, repair, taxes, registration fees, tolls and parking, payload capacity and labor).

DOE labs study on costs and benefits of new transportation technologies the most comprehensive to date

Green Car Congress

Levelized cost of driving (LCOD) across powertrains for light-duty SUV, MY 2025. The report covers light-duty passenger vehicles as well as medium-/heavy-duty commercial vehicles: semi-tractors; medium-duty vans and pickups; transit buses; box, utility aerial and dump trucks; and garbage trucks.

Unifrax introduces new nano-structured alumina catalyst support technology for a greener catalytic conversion option: Eco-lytic

Green Car Congress

This results in increased efficiency due to faster light-off of catalytic performance. The transportation industry is going through an incredible transformation—vehicle manufacturers and regulators are focusing efforts on reducing greenhouse gas emissions and transitioning to electric or plug-in hybrid vehicles.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Typical ultracapacitors are characterized by high power density compared to batteries (but poor energy density), as well as quick charge and discharge. Smaller Ioxus cells offer a power density of 22-28 kW/kg, and larger cells offer densities of 12-15 kW/kg, said Chad Hall, COO of Ioxus. Earlier post.).

Ioxus introduces new iCAP ultracapacitor series with a 3,000F cell

Green Car Congress

Ioxus is targeting a number of markets for the iCAP: transportation drives or systems (comprising several specific sub-groups, notes Chad Hall, Founder and VP Sales); grid power storage; large regenerative energy capture (e.g., Start-stop for micro-hybrid applications. Material handling.

Big Science tools for clean transportation: neutron scattering at ORNL

Green Car Congress

Another major difference is that the intensity of x-ray scattering increases with the electron density of a material; light elements such as hydrogen and lithium thus make very little contribution to scattering. Neutrons, on the other hand, can obtain an appreciable scattering signal from light elements. TAX: Triple-Axis Spectrometer.
