The global power sector is facing a number of issues, but the most fundamental challenge is meeting the rapidly growing demand for energy services in a sustainable way. This challenge is further compounded by the today’s volatile market rising fuel costs, increased environmental regulations, etc. Plant owners are challenged to prepare for the impact of future fuel price increases and carbon tax...

Large scale power production benefits from the high efficiency of gas-steam combined cycles. In the lower power range, fuel cells are a good candidate to combine with gas turbines. Such systems can achieve efficiencies exceeding 60%. High temperature Solid Oxide Fuel Cells (SOFC) offer good opportunities for this coupling. In this paper, a systematic method to select a design according to user ...

The Second Law of thermodynamics is known to be an essential guide for the improvement of energy conversion systems. Throughout the years it has been applied to various engineering methods in particular in methods based on exergy [1] including the 2 Law, thermoeconomics and exergoeconomics. It has also been used in graphically attractive energy integration techniques such as pinch technology an...

The familiarity of mature thermal technologies for brine concentration and crystallization is likely to sustain their widespread deployment despite high capital operational (i.e., energy) costs relative emerging non-thermal alternatives. This critical review analysis evaluates the potential recent innovations in manufacturing devices improved heat mass transfer demonstrably reduce lifecycle the...
