Die Energiewende in Deutschland erfordert neben neuen Übertragungsleitungen für regenerativ erzeugten Strom auch den Bau neuer Speicherkraftwerke. Für das bei Trier geplante Pumpspeicherkraftwerk Rio wurde 2012/2013 ein Raumordnungsverfahren durchgeführt. Der folgende Beitrag dokumentiert...

The calculation of unit cost that can be used for estimating capacity investment decisions is frequently ambiguous due to the many ways to apportion applicable cash ows connected to the delivery of products. This paper studies the identification of relevant unit cost when productive capacity is...

This presentation uses a vehicle simulator and economics model called the Battery Ownership Model to examine the levelized cost per mile of conventional (CV) and hybrid electric vehicles (HEVs) in comparison with the cost to operate an electric vehicle (EV) under a service provider business...

The objective of this task is to compile information regarding batteries which could be use for electric cars or hybrid vehicles in the short term. More specifically, this study applies lead-acid batteries and nickel-cadmium battery technologies which are more developed than the advanced...

Battery charging systems are very important in many developing countries where rural families cannot afford a solar-battery home system or other electricity options, but they can afford to own a battery (in some cases more than one battery) and can pay for it to be charged on a regular basis....

Electric vehicles could significantly reduce greenhouse gas (GHG) emissions and dependence on imported petroleum. However, for mass adoption, EV costs have historically been too high to be competitive with conventional vehicle options due to the high price of batteries, long refuel time, and a...

''GridWise'' is a concept of how advanced communications, information and controls technology can transform the nation's energy system--across the spectrum of large scale, central generation to common consumer appliances and equipment--into a collaborative network, rich in the exchange of...

The Department remains focused on the technologies that are critical to making electric and hybrid vehicles commercially viable and competitive with current production gasoline-fueled vehicles in performance, reliability, and affordability. During Fiscal Year 1994, significant progress was made...
