Incorporating thermal energy storage (TES) into a concentrating solar power (CSP) system extends the power production hours, eliminating intermittency and reducing the Levelized Cost of the Energy (LCOE). The designed TES system was integrated with a 3 kW free-piston Stirling convertor. A NaF–NaCl eutectic salt was chosen as the phase change material (PCM) with a melting temperature of 680 ◦C. ...

Both hydrogen and plug-in electric vehicles offer significant social and environmental benefits to enhance energy security and reduce criteria and greenhouse gas emissions from the transportation sector. However, the rollout of electric vehicle supply equipment (EVSE) and hydrogen retail stations (HRS) requires substantial investments with high risks due to many uncertainties. We compare retail...

Based on results of field testing conducted by the U.S. Department of Energy's National Energy Technology Laboratory (DOE/NETL), this article provides preliminary costs for mercury control via conventional activated carbon injection (ACI), brominated ACI, and conventional ACI coupled with the application of a sorbent enhancement additive (SEA) to coal prior to combustion. The economic analyses ...

Australia possesses the highest average solar radiation of any continent in the world, but solar energy in total contributes less than 1% to Australia’s primary energy consumption. This study intends to assess whether solar photovoltaic (PV) is really a sustainable option for Australia’s energy transition on the project level. A life cycle sustainability assessment (LCSA) was conducted on a 1.2...

Our aim in this paper is to present a brief overview of the scaled hydrokinetic turbine model testing activities in the United States using test turbines specifically designed by the US Department of Energy for its Marine and Hydrokinetic Research and Development program. These test turbines include: (1) a three-bladed horizontal axis turbine (the Sandia turbine) that was designed to demonstrat...

To become more competitive, less dependent on financial support and attractive for investors, wind energy needs to reduce its final cost of energy. According Levelized Cost Energy, there are two ways achieve this goal, by reducing costs or increasing production. Overall Equipment Effectiveness (OEE) is a widely used metric in manufacturing systems, supporting operators enhance productivity oper...

the continuous improvement of eaf performance is crucial for the increase in productivity and cost effectiveness and to render an environmental friendly process. rhi supports these targets by providing a diverse range of refractory and process solutions. chemical energy in practical operation by injection of gaseous media like oxygen and natural gas, and solid materials like carbon have become ...
