Integrated Approach for Green Hydrogen Production and Sustainable Electrification of Railway Platform With Solar Energy Sources

Introduction

The World is approaching a crucial turning point in the energy transition as a result of the quick depletion of fossil resources and the rising concern over climate change. In the middle of this paradigm change, hybrid renewable energy systems - especially those that use solar power technologies have become well known as effective ways to deal with the issues of energy sustainability. By combining these resources, the energy supply is more reliable and there is less chance of blackouts during inclement weather. Energy storage technologies that are included into hybrid systems also make it possible to store excess energy during times of high production. This allows the energy to be used during periods of low production, which improves system efficiency and minimizes waste. India and the majority of other major economies have committed to net zero goals. One of the main prerequisites for reducing emissions is the switch to green ammonia and hydrogen, particularly in the difficult-to-abate industries. An environmentally friendly substitute for fossil fuels is green hydrogen, which is created by electrolysis with the use of renewable energy sources like solar or wind power. Its effective and environmentally friendly application spans several industries:

Transportation: Fuel for Vehicles: Fuel cell electric vehicles (FCEVs), which provide extended ranges and quick refilling akin to gasoline/diesel cars, may be powered by green hydrogen.

Heavy duty transport: Hydrogen fuel cells may be used by trucks, buses, and trains to operate emissions-free, particularly on long-distance routes.

Maritime and aviation: By using hydrogen in fuel cells for ships and airplanes, emissions in these sectors which have historically proven difficult to decarbonize can be decreased.

Infrastructure: The installation of hydrogen filling stations will facilitate a broader adoption, particularly for fleets and public transit.

• Applications in Industry:

  • •

    Hydrogen may be used as a clean fuel or reducing agent in industries with heavy emissions, such as cement and steel manufacture.

  • •

    For the production of industrial heat and electricity, hydrogen can be used as fuel in gas turbines or combined heat and power systems.

  • •

    Hydrogen is an essential feedstock that lowers carbon footprints in the manufacturing of ammonia, refining, and other chemical processes.

  • •

    When renewable energy output is low, excess energy can be used for electrolysis to produce hydrogen for later consumption.

  • •

    Hydrogen's ability to hold energy for extended periods of time is essential for counteracting seasonal fluctuations in the output of renewable energy.

• Water Conservation and its Effects on the Environment:

  • •

    Electrolysis: Using renewable power, electrolysis splits water into hydrogen and oxygen to make green hydrogen.

  • •

    Water Recycling: In an effort to consume less freshwater, efforts are being made to recycle the water used in electrolysis.

  • •

    Environmental Benefits: Electrolysis with renewable energy lowers pollutants and greenhouse gas emissions.

  • •

    Local Impact: Green hydrogen generation may help communities and local ecosystems by lowering pollution and water use.
