Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

Importantly for scalability, the cell-level cost of the aluminum–sulfur battery is projected to be less than one-sixth that of current lithium-ion technologies. The smaller scale of the aluminum-sulfur batteries would also make them practical for uses such as electric vehicle charging stations, Sadoway says.

Georgia Tech study suggests unlinking EVs from CAFE and coordinating with power sector for low-cost benefits

Green Car Congress

However, managed EV adoption can reduce the cost of achieving GHG reductions through a RES, they concluded in their paper published in the ACS journal Environmental Science & Technology. They assumed a gasoline price of $4/gallon (2009 $). Uncontrolled charging is the current norm.

Lux Research: fuel cell vehicles lag other drivetrains in terms of cost of ownership; ICE and HEV lowest cost

Green Car Congress

Based on an analysis of various cost of ownership scenarios for various drivetrains, including internal combustion engine (ICE) gasoline and diesel; hybrid (HEV); battery-electric (EV); plug-in hybrid electric (PHEV); and fuel cell vehicles, Lux Research concludes that fuel cell vehicles (FCVs) are “ solidly in a laggard position. ”.

SOFC-maker Bloom Energy announces initial strategy for hydrogen market entry; partnership with SK

Green Car Congress

Both companies have committed to fund and to resource these two phases fully. Over time, it has improved the efficiency and aggressively reduced the cost of its products and expects this trend to continue. Generating low-cost hydrogen from intermittent renewables is a sine qua non for decarbonization.

New catalysts convert ethanol to butanol with high selectivity; potential low-cost upgrade for ethanol plants

Green Car Congress

While butanol has emerged as a potential sustainable liquid fuel replacement for gasoline, development of biosynthetic pathways for its synthesis are challenged by very low conversion and modest selectivity, they noted. Quite simply, they are the world’s best catalysts for making the gasoline of the future.

Study finds wide range in GHG intensities and production costs of cellulosic ethanol from corn stover, switchgrass and miscanthus

Green Car Congress

In their study, published in the ACS journal Environmental Science & Technology they found that—compared to gasoline—the GHG savings from miscanthus-based ethanol ranged between 130% and 156% whereas that from switchgrass ranged between 97% and 135%. Production cost of ethanol is annualized over the simulation period.

Study shows bamboo ethanol in China technically and economically feasible, cost-competitive with gasoline

Green Car Congress

Now, researchers at Imperial College London have shown that bioethanol production from bamboo in China is both technically and economically feasible, as well as cost-competitive with gasoline. The economic analysis found that the lowest enzyme loading had the most commercially viable scenario (production cost of $0.484 per liter (US$1.83/gallon
