Green hydrogen has emerged as a focal point in the global pursuit of decarbonisation, with India leading the charge through its National Green Hydrogen Mission. The country has set ambitious goals for green hydrogen production, aiming for 5 million tonnes by 2030 and investing significantly in the necessary infrastructure. Green hydrogen, produced through electrolysis from renewable energy sources, is seen as a key component in achieving India's sustainable development targets and transitioning to a cleaner energy future. Global trends indicate a potential market value of $11 trillion by 2050 for green hydrogen, with countries like Europe, Japan, and South Korea making strides in production and adoption. Despite challenges such as high production costs and infrastructure development, optimism remains high for green hydrogen's role in the energy transition. Public awareness and government support are crucial for the successful adoption of green hydrogen, with surveys showing significant interest in Fuel Cell Electric Vehicles (FCEVs) and optimism towards government initiatives. Overcoming challenges in cost, infrastructure, and awareness will be essential for realizing the full potential of green hydrogen in achieving sustainable energy goals globally.
