High cost and technical immaturity of bulk (multi-hour) electricity storage (BES) systems are often cited as major hurdles to increasing the penetration of intermittent renewables. We use a simple model to assess the economics of BES under carbon emissions constraints. Size and dispatch of a green-field generation fleet is optimized to meet a variable load at a 15 minute time resolution. Electr...

The environmental impacts of fossil-fueled electricity drive interest in a cleaner electricity supply. Electricity from wind provides an alternative to conventional generation that could, in principle, be used to achieve deep reductions ð450%Þ in carbon dioxide emissions and fossil fuel use. Estimates of the average cost of generation—now roughly 4b=kWh—do not address costs arising from the spa...

Fluctuations of electric load call for flexible generation technologies such as gas turbines. Alternatively, bulk energy storage (BES) facilities can store excess off-peak electricity to generate valuable peaking electricity. Interest in electricity storage has increased in the past decade in anticipation of higher penetration levels of intermittent renewable sources such as wind. Compressed Ai...

In power grids, there must always be a balance between energy production and consumption. Due to the variable nature of consumers, energy production should also be subject to these changes. Electricity storage is one of the most important issues in the electricity industry, which can generate many ancillary services such as load curve leveling, peak shaving, integration with renewable units, ro...

Integration of energy storage resources into electricity markets face multiple barriers including high capital costs, sitting difficulties, significant energy penalties due to roundtrip efficiency, and the lack of market structures that appropriately reflect the value of storage. Capital and operating costs could be reduced with advanced storage systems consisting of modular multilevel series/p...

The electrochemical reduction of CO2 has been extensively studied over the past decades. Nevertheless, this topic has been tackled so far only by using a very fundamental approach and mostly by trying to improve kinetics and selectivities toward specific products in half-cell configurations and liquid-based electrolytes. The main drawback of this approach is that, due to the low solubility of C...

Sharing economy is a transformative socio-economic phenomenon built around the idea of sharing underused resources and services, e.g. transportation and housing, thereby reducing costs and extracting value. Anticipating continued reduction in the cost of electricity storage, we look into the potential opportunity in electrical power system where consumers share storage with each other. We consi...

Decentralized power generation may lead to operational problems in electricity distribution networks, such as current overloads and too large voltages deviations. Storage systems can have a beneficial effect to alleviate these problems. However, these systems are relatively very expensive and have not been applied much in electricity grids in Europe. We present an optimization model which can b...
