Siemens presents three-point plan for implementing cost-efficient energy transition in Germany

Green Car Congress

Relying on a higher share of efficient, low-emission combined cycle power plants and wind energy could save €150 billion (US$200 billion) by 2030 while attaining the same CO 2 targets, Siemens says. However, the financial cost of the shift is causing concern. Source: Siemens. Click to enlarge. One possibility here is auctions.

Two studies exploring battery costs for hybrids and plug-ins: LEESS, PHEV20, and PHEV40

Green Car Congress

For PHEV20 batteries, TIAX found significant overlap in battery costs among five cathode classes, with wider variation within each chemistry based on the electrode design than between chemistries. Cell formation and aging, anode and cathode coating and drying, and winding account for as much as 70% of the total processing costs.
