The integration of ecological solutions in the national economy, including on the railway, is very important, because Latvia has already identified himself the task of becoming the greenest country in the world, emphasizes the Vice-President of Latvian railway, INIS Sturmanis. He notes that many countries are increasingly choosing environmentally friendly transport for both passengers and for freight. LDz in the future can develop in several ways, including through electrification, but to carry it everywhere is impossible, therefore, in parallel work on the project hydrogen engine, the prototype of which can be seen in the Latvian pavilion at the Astana EXPO 2017. "Now we are working to create, as far as we know, the world's first hydrogen shunting locomotive", said A. Sturmanis.
Introducing the audience with the developed jointly with the Latvian railway project hydrogen shunting locomotive, the Chairman of the Latvian hydrogen Association Aivar Old explained that hydrogen is not an energy source but a carrier of energy that allows you to use it especially effectively. "We're not the only one who looks in this direction. For example, the company ALSTOM in March of this year began testing a passenger train running on hydrogen, and Latvia, introducing the hydrogen driving force for the transport of goods, has the opportunity to become one of the leaders in this field", — shared his plans for the production of hydrogen locomotive A. Starikov.
Chief engineer of LLC "LDz ritošā sastāva serviss" Fedor Mikhailov told the participants about the work done by the Latvian railway in the course of implementing several environment-related projects. The company has already several years engaged in cleaning the environment in the historical areas of contamination near the shops of the equipment of locomotives, and maintenance, where for decades systematically leaking oil and other substances. In turn, at present, after modernization, a few shunting and mainline locomotives, significantly reduced the fuel consumption and the amount of required, as well as the amount of CO emissions2.
Presented at the Astana EXPO 2017 prototype hydrogen-powered locomotive "Hyloco" was made to showcase the latest technologies in this field. With additional visualization options every visitor of the Latvian pavilion can examine in detail the principle of operation of this locomotive. The potential of this project last week and praised the representatives of the Kazakhstan Railways, Latvian railway participated in organized discussions.
When you use a locomotive running on hydrogen, the pulling power is planned to provide with batteries 250 kWh hybrid system of a hydrogen fuel cell with a capacity of about 400 kW, while the system of reservoirs for the storage of hydrogen in the amount of 120 kg maximum load will provide at least 20 hours of continuous operation between refills. To run his locomotive with a high pressure run hydrogen from the cylinders is directed to the fuel cell where it mixes and reacts with the air, is converted into electricity and water. Further, the electricity from the cells falls in a special system, as necessary, governing the supply of electricity — either from the motors or the battery.
