A report last month by IdeaWorks, an airline revenue consultant, noted that "airlines all over the world have been watching this demonstration of ancillary revenue power" by carriers in the United States, and many are devising similar initiatives, especially for flights within Europe.
But increasingly, some ancillary functions, like power steering or power brake pumps, or air-conditioning, are performed by electric motors, to lower the load on the internal combustion engine and improve gas mileage.
Using hydrogen-based solutions to provide ancillary services for power system operation, such as frequency control and power balancing etc., would offer another promising value stream to hydrogen technology developers.
Among all the ancillary equipments, the power consumption of air compressor is the greatest, typically accounting for up to 80%% power of the overall ancillary equipments and 15 %–20 % of the fuel cell system [2, 4].
All the ancillary electronics, the power, transistors and circuitry, are things today that are not yet fully flexible at large scales".
Grid connected energy storage systems are expected to play an essential role in the development of Smart Grids, providing, among other benefits, ancillary services to power grids.
Among the various ancillary services, reactive power appears to be the one that least lends itself to competitive procurement due to its electrical characteristics.
To solve that problem, they went about inventing a system that could power ancillary equipment without the use of an engine.
Ancillary services are power-related services held in reserve in case of unexpected situations.
