During Bhutanese Prime Minister Tshering Tobgay's visit to India, Indian Petroleum and Natural Gas Minister Hardeep Singh Puri unveiled India's first green hydrogen fuel cell bus in New Delhi. The bus, powered by green hydrogen, emits only water vapor, making it an environmentally friendly mode of transportation compared to traditional diesel and petrol buses. The launch was attended by both Prime Minister Tobgay and Indian Prime Minister Narendra Modi, who highlighted the significance of sustainable energy in India's future. Green hydrogen, produced from renewable sources like wind and solar power, presents a clean energy alternative that can reduce carbon emissions and establish India as a leader in clean energy technology. The hydrogen fuel cell bus project aims to decarbonize public transport and address environmental challenges, especially in cities like New Delhi that struggle with air pollution. While the technology offers advantages like zero tailpipe emissions and quick refueling times, challenges such as high production costs and infrastructure development remain. India's Green Hydrogen Policy seeks to incentivize investments and reduce the cost of green hydrogen production, positioning the country as a key player in the global green energy market. Collaborations with international clean energy firms and the National Hydrogen Mission further demonstrate India's commitment to a sustainable and greener future.
