Cost of Electricity Interruption to Commercial and Industrial End-Users
The question ‘what is the cost of electricity interruptions?’ is fraught with lots of complexities as electricity interruption is not a tradable commodity. A closely associated question is ‘from whose perspective should this cost be assessed – the electric utility or its customers?’ Extant research …

System level design enhancements for cost effective renewable power generation by reverse electrodialysis
Studies of the future competitiveness of reverse electrodialysis (RED) with other energy technologies show that the projected levelized cost of electricity realized through current stack designs is prohibitively high. Despite these high projected costs, RED maintains other advantages - namely, the …

Studies in Pressurized Oxy-Combustion: Process Development and Control of Radiative Heat Transfer
<p>Fossil fuels supply over 80% of the world’s primary energy and more than two-thirds of the world’s electricity. Of this, coal alone accounts for over 41% of the electricity supplied globally. Though coal is globally well-distributed and can provide stable and reliable energy on demand, it emits …
