Maximising revenue for non-firm distributed wind generation with energy storage in an active management scheme [PDF]

open access: yes, 2013
The connection of high penetrations of renewable generation such as wind to distribution networks requires new active management techniques. Curtailing distributed generation during periods of network congestion allows for a higher penetration of ...

Compressed Air Energy Storage-Part I: An Accurate Bi-linear Cavern Model

open access: yes, 2017
Compressed air energy storage (CAES) is suitable for large-scale energy storage and can help to increase the penetration of wind power in power systems. A CAES plant consists of compressors, expanders, caverns, and a motor/generator set.

Hydrogen-fueled engine [PDF]

open access: yes, 1978
A hydrogen-oxygen fueled internal combustion engine is described, which utilizes an inert gas, such as argon, as a working fluid to increase the efficiency of the engine, eliminate pollution, and facilitate operation of a closed cycle energy system. In a

Free energy barrier for molecular motions in bistable [2]rotaxane molecular electronic devices [PDF]

open access: yes, 2009
Donor−acceptor binding of the π-electron-poor cyclophane cyclobis(paraquat-p-phenylene) (CBPQT^(4+)) with the π-electron-rich tetrathiafulvalene (TTF) and 1,5-dioxynaphthalene (DNP) stations provides the basis for electrochemically switchable, bistable ...

Continuity and boundary conditions in thermodynamics: From Carnot's efficiency to efficiencies at maximum power

open access: yes, 2015
[...] By the beginning of the 20th century, the principles of thermodynamics were summarized into the so-called four laws, which were, as it turns out, definitive negative answers to the doomed quests for perpetual motion machines.

REVISITING COMPRESSED AIR ENERGY STORAGE. [PDF]

open access: yes, 2015
The use of renewable energies as a response to the EU targets defined for 2030 Climate Change and Energy has been increasing. Also non-dispatchable and intermittent renewable energies like wind and solar cannot generally match supply and demand, which ...
