In various areas Siemens is committed to helping refugees. In spring 2015 the eight week internship program started and has now been extended to 14 locations. Siemens is also offering six-month special training courses. These courses encompass intensive language instruction as well as pre-vocational training in the areas of mechanics and electronics. The goal is to enable the participants to get an apprenticeship training position. Siemens Real Estate is making space available on a temporary basis at 15 different locations throughout Germany, among these locations are Munich and Erlangen. Countless employees all across Germany have also offered their help and participated in a wide range of donation and aid campaigns.
In May 2014 Siemens, together with the public utilities of Mainz, Linde and the RheinMain University of Applied Sciences, has laid the foundation stone for a new type of energy storage system. Now, time has come: By pressing a symbolic button, the Chairman of the Board of Linde Group, Dr. Wolfgang Büchele, Siemens board member Professor Siegfried Russwurm, two board members of Stadtwerke Mainz AG, Detlev Höhne and Dr. Tobias Brosze, and Professor Dr. Detlev Reymann, President of RheinMain University, officially launched a hydrogen production plant at the Energiepark Mainz on July 2, 2015. With the support of the German Federal Ministry of Economics and Technology as part of the Energy Storage Funding Initiative the 17-million-project could be realized. The system, equipped with an electrolyzer from Siemens, will convert surplus electricity from wind farms to hydrogen from now on. In this way, it will be possible to store electricity from renewable sources over longer periods of time. With a peak rating of up to 6 megawatts the plant is the largest of its kind in the world.
The principle of electrolysis has been tried and tested for decades. What is special about the Mainz system is that it involves highly dynamic PEM high-pressure electrolysis which is particularly suitable for high current density and can react within milliseconds to sharp increases in power generation from wind and solar sources. In this electrolyzer a proton exchange membrane (PEM) separates the two electrodes at which oxygen and hydrogen are formed. On the front and back of the membrane are precious-metal electrodes that are connected to the positive and negative poles of the voltage source. This is where the water is split. The system in Mainz will thus have a capacity relevant for bottlenecks in the grid and small wind farms.
The first passenger train will roll through the Gotthard Base Tunnel early June 2016. Siemens has supplied the tunnel control and fire protection systems for the world's longest railway tunnel. The sophisticated safety system has over 200,000 sensors, and places maximum demands on logistics and data processing.The control system controls and monitors all installations completely automatically. The tunnel is fitted with sensors, control electronics and surveillance equipment. This includes video cameras in the multifunction points, which are connected by optical fiber cables to two tunnel control centers located at the north and south entrances. Siemens has installed a tunnel control system in each center, each system acting as a reserve for the other. The movement of each train is recorded, and displayed in the control center. The system controls the entire infrastructure, which has 3,200 kilometers of electrical cables and 2,600 kilometers of data cables. It detects a door that has not been closed properly or a light that has failed. When required, the ventilation system is activated, the light at the next emergency stop point is switched on, and the doors are opened automatically. What is actually happening is seen on screen by the around 60 employees on duty in the centers. "Events" are classified according to five alarm stages. The system provides information and decision-making steps for each stage to help the head of operations. Sensors check the trains for overheated brakes and leaks before they enter the tunnel and without requiring them to stop. However, the main task of the new system is to maintain availability. The maintenance periods, such as close-down times and spare parts requirement, can be efficiently planned with a new tool.It goes without saying that safety is paramount in a tunnel where in the near future more than 200 trains a day will barrel through the tubes at speeds up to 250 km/h. The tubes are connected every 300 meters by crosscuts that allow train passengers to escape to the other tube in case of a fire. Each tube has two emergency-stop stations 600 meters in length which allows the evacuation of up to 1,000 passengers.
Siemens announced today that it has started a 15-year technical support and spare parts supply agreement with the U.S. passenger rail operator Amtrak for its 70 new Siemens ACS-64 electric locomotives in operation on the Northeast Corridor. This is Siemens' largest technical support contract for passenger locomotives to-date in the U.S. In 2010, Amtrak ordered 70 Amtrak Cities Sprinter electric locomotives from Siemens. The first locomotives are already in passenger service.
