3 winners of DOE’s “America’s Next Top Energy Innovator” Challenge: hydrogen-assisted lean-burn engines, graphene for Li-air and -sulfur batteries, and titanium process

Green Car Congress

Vorbeck Materials , a startup company based in Jessup, Maryland, is using a Pacific Northwest National Laboratory (PNNL)-developed method for developing graphene for better lithium air and lithium sulfur batteries. These Liquid Desiccant HVAC systems deliver a 50 - 75% reduction in energy usage over conventional HVAC units.

Systematic review of EV battery pack costs suggests economies of scale may push cost toward US$200/kWh without further cell chemistry improvements

Green Car Congress

Industry-wide cost estimates for battery packs for electric vehicles have declined by approximately 14% annually between 2007 and 2014, from above US$1,000 per kWh to around US$410/kWh, according to a systematic review of more than 80 different estimates by a team from the Stockholm Environment Institute.

New aqueous rechargeable lithium battery shows good safety, high reliability, high energy density and low cost; another post Li-ion alternative

Green Car Congress

Aqueous rechargeable lithium batteries (ARLBs), which use aqueous electrolytes and lithium intercalation compounds as electrode(s) based on redox reactions, were invented in 1994 and have attracted wide attentions since 2007 as a promising system because of their low capital investment, high reliability and good safety.

The Net-Zero Neighborhood: Advanced Energy Storage and Highly Efficient Photovoltaics Take Transportation Off the Gasoline Grid and Residential Off the Electric Grid

Green Car Congress

Ab initio materials, design, performance, and manufacturing can initially be handled with petascale (1 x 10 15 op/s) computation, Weigand suggests. Weigand is looking for a “500-mile battery” such as a Li-O 2 (Lithium air) thin film nano-technology system and for 50% efficient photovoltaic cells.
