NREL report finds electrified heavy-duty vehicle powertrains could provide lower total cost of ownership than diesel under certain conditions

Green Car Congress

Chad Hunter, lead author of the report and former NREL researcher. To further the analysis, researchers compared the powertrains for multiple timeframes to illustrate how battery and hydrogen fuel price reductions are key to accelerating medium- and heavy-duty vehicle electrification. —Hunter et al.

New DuraBlue ultracaps from Maxwell increase shock and vibration tolerance, energy and power capacity

Green Car Congress

This enhanced shock and vibration tolerance is particularly important in the transportation market—especially mass transit—and in developing markets in which the road infrastructure might not be quite as smooth as in more developed ones, noted Chad McDonald, director of product marketing. —Chad McDonald.

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

Green Car Congress

We use vehicles modeled in Autonomie to estimate vehicle costs and fuel economy along with fuel price projections from the Energy Information Administration (EIA), and focus on developing internally consistent estimates for other relevant cost parameters.

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

Green Car Congress

Hydrogen-powered fuel cell electric vehicles will reach cost parity with conventional vehicles as the price of hydrogen falls. Battery electric vehicles, meanwhile, will reach cost parity as battery prices drop. Overall, hybrid electric vehicles tend to be the lowest-cost powertrain. —David Gohlke.

Ioxus unveils 16V/58F iMOD ultracapacitor module series for alternative energy markets

Green Car Congress

With the increase in adaptation of hybrid drives and clean technologies, there is a high demand for more rugged, compact and lower-price ultracapacitor modules with improved cell balancing. —Chad Hall. You can go up to 750V without any external management, you can run it in parallel to a 12V battery or replace a 12V battery.

Ioxus Introduces 1,000-, 3,000- and 5,000-Farad Ultracapacitor Cells with Higher Power Densities

Green Car Congress

Chad Hall, Ioxus COO. The new 1,000-, 3,000- and 5,000-F ultracapacitors are available at www.ioxus.com, starting at the following prices for low volume: 1,000F, 2.7V The ESR is the same as that of higher capacitance products. In general, as capacitance does up, the ESR goes down. ultracapacitors - $62. ultracapacitors - $90.

NREL study finds high-pressure hydrogen pipeline system could potentially make hydrogen cost-competitive with gasoline

Green Car Congress

However, owing to small scale and limited competition, dispensed hydrogen fuel prices currently are higher, averaging about $16.30/kg kg in California in the third quarter of 2018. About half of the levelized cost of retail station hydrogen can be attributed to hydrogen delivery, compression, and dispensing costs. —Penev et al.
