ONE of the first Siemens Avenio light rail vehicle (LRV) equipped with a nickel-metal hydride hybrid energy storage system is being tested ahead of delivery to Qatar.
Canadian Energy Storage Systems manufacturer Corvus Energy and Siemens have been awarded a contract to supply lithium energy storage systems to hybrid passenger ferries.
German-Danish ferry operator’s Scandlines agreed to have its M/V Berlin and M/V Copenhagen ferries fitted with a 1,050VDC, 1.5MWh ESS built from 231 Corvus Energy AT6500 advanced lithium polymer batteries.
The batteries will be used alongside a Siemens converter system and powered by four diesel gensets.
The AT6500 Lithium Polymer battery will provide 6.5kWh of energy in a ~2.5 cubic foot volume. Weighing 65kg, it is available in 12V, 24V, 48V and 96V configurations.
The hybrid propulsion system will also be equipped with a scrubber to clean the engines of exhaust streams of pollutants, which - according to a statement from Corvus - is expected to reduce sulphur emissions by “at least 90%.”
“The M/V Berlin and M/V Copenhagen are examples of the significant benefits both operationally and environmentally of battery hybrid propulsion,” Andrew Morden, President and CEO of Corvus Energy said.
The ferries will have a similar system to the ESS Corvus and Siemens delivered to the hybrid vessels currently operating on Scandlines’ Puttgarden-Rødby route.
Each ferry will have the capacity to carry 1,300 passengers and 460 cars or 96 trucks.
South Korea's LG Chem and Siemens have agreed to collaborate more closely on development and marketing of industrial battery energy storage systems (ESS).
The two companies signed a preliminary deal at Siemens' German headquarters in Erlangen, Bayern to cooperate on several major ESS projects over the next few years.
Siemens has struck a deal with US service provider Direct Energy to install its demand response management system (DRMS).
Direct Energy will manage the existing load commitments in several independent system operators (ISO) with Siemens’s DRMS. The DRMS are designed to control power usage and to help managing power demand requirements particularly during peak times.
The DRMS is to be integrated with sub-metering devices located at each Direct Utility account and to collect consumption data. The service provider will then use the data to determine the amount of energy it needs to transact into the marketplace.
"The flexibility of Siemens DRMS to provide automated interfaces to multiple ISO systems will allow Direct Energy to operate their portfolio in a more streamlined and efficient manner and will improve reliability for all of their customers," said Craig Cavanaugh, director of Siemens Smart Grid Applications and Solutions. “By leveraging the forecasting and analytics engine embedded in Siemens DRMS, Direct Energy will be able to optimize the market based transactions,” he added.
The deal will enable Direct Energy to deploy its demand reduction and demand management programs throughout the US and Canada. The company has more than six million residential and commercial customers.
Germany-based Siemens said that the US-contract is its biggest demand response project so far.
Siemens Industry and Aquion Energy have signed a memorandum of understanding (MOU) to integrate its battery and drive technologies to develop microgrid and grid energy storage systems.
The companies will test the integration of Aquion's AHI (‘Aqueous Hybrid Ion’ saltwater electrolyte chemistry) and Siemens' Sinamics S120 drive technology. As part of the MoU, Siemens acquired an initial set of Aquion batteries for immediate shipment to their manufacturing and test facility in Alpharetta, Georgia, US.
