Empirical Evaluation of V2G Round-trip Efficiency
2020 International Conference on Smart Energy Systems and Technologies (SEST), 2020The business case of vehicle-to-grid (V2G) technology and its potential to provide grid services is heavily dependent on the round-trip efficiency of this technology. Surprisingly, very little empirical research is conducted to determine the V2G round-trip efficiency of electric vehicles currently available in the market, resulting in a wide range of ...

Efficient Round-Trip Time monitoring in OpenFlow networks
IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications, 2016Monitoring Round-Trip Time provides important insights for network troubleshooting and traffic engineering. The common monitoring technique is to actively send probe packets from selected vantage points (hosts or middleboxes). In traditional networks, the control over the network routing is limited, making it impossible to monitor every selected path ...

Electric round-trip efficiency of hydrogen and oxygen-based energy storage
International Journal of Hydrogen Energy, 2005An electrolyzer and a fuel cell have been integrated in a small-scale stand-alone renewable energy system to demonstrate that hydrogen can be used for long-term stationary energy storage. The economic and environmental performance of such a system is strongly related to the ability of the electrolyzer to convert electrical energy to hydrogen and the ...

Replica-exchange enveloping distribution sampling (RE-EDS) allows the efficient estimation of free-energy differences between multiple end-states from a single molecular dynamics (MD) simulation. In EDS, a reference state is sampled, which can be tuned by two types of parameters, i.e., smoothness parameters(s) and energy offsets, such that all end ...

Analysis of Round Trip Efficiency of Thermal Energy Storage in Northern Arizona
ASME 2019 Power Conference, 2019Abstract Energy storage systems provide a variety of benefits, including taking better advantage of renewable electricity when available and smoothing demand by shifting demand peaks to times when electricity prices and demand are lower. When low electricity demand occurs during the nighttime, system wide advantages also occur.

ECS Meeting Abstracts, 2023
A Unitized Reversible Fuel Cell (URFC) system provides many benefits for energy storage by combining a fuel cell and an electrolyzer into a single stack, thus simplifying the system while decreasing weight, footprint, and material costs. URFC systems usually have low overall efficiency due to conflicting optimal operating conditions required for ...

An efficient method to produce single-walled carbon nanotubes by round-trip arc discharge
Materials Chemistry and Physics, 2006Abstract By using a tungsten rod as cathode and exchanging the electrodes after each discharge, large amount of single-walled carbon nanotubes (SWCNTs) were produced by an improved arc discharge method, in which the Y–Ni–C composite rod was used as anode.
