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. —David Gohlke.

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).

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.).

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. Simmons, B., and Singh, S.
