Indian Railways is going to limit their fuel usage by installing solar panels and battery packs on 250 trains. The Economic Times that six cars will initially get the additions. They'll be attaching flexible 4.5 kilowatt solar panels and lithium-ion batteries that are either 110 or 120 volts. These will be tested out in the public for two months.
Evaluation will be made on how the solar panels attached to the trains will absorb the sun’s energy. Hero Future Energies’ CEO, Sunil Jain, explained how these panels would impact the cars in the report. “Flexible solar panels on moving trains is a good idea. However, efficiency of solar panels on moving trains is something which needs to be seen...Additionally, these panels would also increase the weight of the train requiring extra fuel to move them.”
There’s further plans on a larger scale. Indian Railways can run 25 percent of their energy from sustainable sources by 2025. Based on studies released from the Council on Energy, Environment, and Water, it would require an investment of $3.6 billion US. They would be able to install five gigawatts of capacity and this would be completed over the next few years. 3.9 gigawatts would be for utility-scale projects while rest are rooftop-based.
All of this solar production is only the beginning, and it’s completely affected the coal industry. Not only is Coal India shuttering lots of mines in the next year, but 14 gigawatts of planned coal-fired power plants have been scrapped. That’s good news for urban areas that are for longer than a half hour.
