Increasing global demand for fresh water is driving the development and implementation of a wide variety of seawater desalination technologies driven by different combinations of heat, work, and chemical energy. This paper develops a consistent basis for comparing the energy consumption of such technologies using Second Law efficiency. The Second Law efficiency for a chemical separation process...

Almost all clean hydrogen that is used in industry made by cogenerating low-cost and other commodities. We propose a framework to make the world's from cogeneration processes.

Sustainable economic development requires the efficient production and use of energy; combined heat and power (CHP) systems contribute to both of these goals. While a recent executive order set a national goal of 40 GW of new industrial CHP by 2020, the deployment of CHP is challenged by financial, regulatory, and workforce barriers. Discrepancies between private and public interests can be min...
