ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Exergy Efficiency of Closed and Unsteady-Flow Systems
Exergy efficiency is viewed as the degree of approaching reversible operation, with a value of 100 percent for a reversible process characterized by zero entropy generation or equivalently zero exergy destruction since Xdestroyed = T0Sgen.

The feasibility of using a hybrid flat‐plate solar collector–organic Rankine cycle–proton exchange membrane system for the generation of electricity, heat, and hydrogen simultaneously is analyzed. The energy efficiency of the solar thermal system reaches 23.82%, and hydrogen production of up to 13.62 kg/month is achieved while reducing CO2 emissions ...

Exergy Analysis of a Desiccant Cooling Cycle Recovering Heat from Hot Exhaust
The manufacturing processes of industrial gases are major consumers of energy as electricity or fossil fuel. A big part of this energy ends up as heat in the process gas at temperatures around 150°C.

Abstract This paper presents a two‐stage model for planning a renewable energy portfolio by balancing economic, social and environmental sustainability goals. The first stage addresses a multi‐objective problem where conflictive impacts generated by the energy portfolios should be optimised according to the corresponding economic, social or ...
