SEPTA, Constellation, and Viridity Energy to deploy 8.75MW energy storage system to capture and reuse subway train braking energy
January 22, 2016
An 8.75MW battery storage network which will capture and reuse the energy created by braking subway cars will help Southeastern Pennsylvania Transportation Authority (SEPTA) reduce operating costs, ensure energy resiliency, and support the stability of the electrical grid.
Constellation, a subsidiary of Exelon Corporation, will fund, own, and operate the 8.75MW battery storage network, deployed at seven SEPTA substations. The network is designed to use stored energy to power trains as they accelerate from stations and can provide emergency generation for trains in the event of a power outage. ABB will provide engineering, procurement, construction and operations services to Constellation for the project. Saft will provide the lithium-ion battery technology.
Bombardier battery-electric powered tram sets range record: 25.9 miles of catenary-free operation
November 06, 2015
Bombardier Transportation has successfully completed a 41.6 km (25.9 miles) catenary-free test run using a Bombardier-built tram, powered entirely by its PRIMOVE battery in combination with BOMBARDIER MITRAC (Modular Integrated TRACtion system). The test run was conducted in the German city of Mannheim on the Rhein-Neckar-Verkehr GmbH (RNV) network.
RNV began using SuperCaps energy storage systems in 2009, and has integrated this technology into 30 of their trams. This provided sufficient energy for short catenary-free operation (CFO) distances. However, the latest generation of Bombardier’s PRIMOVE battery system has been specifically developed for use with CFO where greater distances need to be covered.
Audi using Alstom H3 plug-in hybrid shunting locomotive at Ingolstadt
October 30, 2015
Audi has begun using a new 1,000 horsepower plug-in hybrid shunting locomotive manufactured by Alstom in daily operations at the Audi plant in Ingolstadt, Germany. The new locomotive runs without any emissions inside the plant buildings and can operate for up to two hours at a time in purely electric mode. Its battery is plugged in during breaks for recharging with CO2‑free electricity, or is supported while in motion by a diesel engine.
The three-axle Alstom H3 hybrid locomotive is significantly quieter than its conventional counterparts, and can deliver up to a 50% reduction in diesel fuel use, with a concomitant reduction in CO2emissions. This means that the plug‑in‑hybrid locomotive emits up to 60 tons less CO2 each year. For the Ingolstadt plant, this is another stage on the way to the CO2‑neutral factory.
DDFlyTrain flywheel hybrid technology to deliver around 10% fuel savings, rapid ROI
June 17, 2015
The DDFlyTrain research project, conducted by Ricardo, Artemis Intelligent Power (a group company of Mitsubishi Heavy) and Bombardier Transportation, (earlier post) has projects a fuel savings of around 10% based on the use of high speed flywheel brake recovery technology retrofitted to Diesel Multiple Unit (DMU) rolling stock. This order of saving means that the technology has a potential return on investment (ROI) of inside five years.
The DDFlyTrain hybrid solution—designed for integration onto a Bombardier Turbostar DMU—is based on Ricardo’s TorqStor high-speed flywheel energy storage technology and the high efficiency Artemis Digital Displacement hydraulic pump-motor transmission. (Earlier post.) The project has also produced a proof of concept test rig used to demonstrate the technology to rail industry stakeholders and a concept for integration onto a Bombardier Turbostar DMU.
Hydrogenics and Alstom Transport to develop and commercialize H2 fuel-cell commuter trains in Europe; €50M, 10-year agreement
May 27, 2015
Hydrogenics Corporation, a leading developer and manufacturer of hydrogen generation and hydrogen-based power modules, signed a 10-year exclusive agreement to supply Alstom Transport with hydrogen fuel cell systems for Regional Commuter Trains in Europe. Alstom Transport is a unit of Alstom, a France-based global leader in power generation, transmission and rail infrastructure with sales of €6.2 billion.
The agreement, valued at more than €50 million, includes the supply of at least 200 engine systems along with service and maintenance as necessary over a 10-year period. The fuel cell systems, based on Hydrogenics’s Heavy-Duty HD series fuel cells, will be developed to meet European train compliance regulations. The first units are expected to be delivered in 2016 following prototype work slated for late 2015.
