class=\"wp-block-list\">\n<li><strong>Green Hydrogen:<\/strong> The hydrogen produced via electrolysis, the splitting of water into hydrogen and oxygen with electricity generated from renewable energy sources such as solar or wind, is known as Green hydrogen.<\/li>\n\n\n\n<li><strong>MNRE defines Green Hydrogen<\/strong> as having a well-to-gate emission (i.e., including water treatment, electrolysis, gas purification, drying and compression of hydrogen) of not more than <strong>2 kg CO2 equivalent \/ kg H2.<\/strong><\/li>\n\n\n\n<li><strong>Gujarat\u2019s Kandla port<\/strong> is the first in India to have an operational Green Hydrogen plant using indigenous Electrolysers.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full

Security:<\/strong> India is the <strong>third-largest oil consumer and fourth-largest crude oil importer,<\/strong> and hydrogen technology will play a key role in reducing this reliance.<\/li>\n\n\n\n<li><strong>Industrial Decarbonisation:<\/strong> Can replace fossil fuels in hard-to-abate sectors \u2013 steel, cement, ammonia, refineries.<\/li>\n\n\n\n<li><strong>Clean Mobility:<\/strong> Powering fuel cell vehicles, trains, and ships.<\/li>\n\n\n\n<li><strong>Grid Stability: <\/strong>Acts as an energy storage medium for intermittent renewables.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Challenges<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Risks associated with the transportation:<\/strong> Hydrogen in gaseous form is highly inflammable and difficult to transport, thereby making safety a primary concern.<\/li>\n\n\n\n<li><strong>High Production Costs:<\/strong> The <strong>levelized cost of electricity (LCOE) and electrolyzer costs<\/strong> are major factors driving up the overall production costs.<\/li>\n\n\n\n<li><strong>Disparity in Production Costs:<\/strong> A substantial disparity between <strong>green hydrogen production costs ($5.30- $6.70 per kg)<\/strong> and traditional grey\/blue hydrogen production costs ($1.9-$2.4 per kg).<\/li>\n\n\n\n<li><strong>Technological Readiness: <\/strong>The adoption rates and risk factors associated with futuristic technologies pose challenges for financing and scaling up production.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Government initiatives for Green Hydrogen<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>National Green Hydrogen Mission: <\/strong>The mission was launched in<strong> 2023<\/strong> with an outlay of <strong>Rs. 19,744 crores. <\/strong>It lays out a comprehensive roadmap to:\n<ul class=\"wp-block-list\">\n<li>Identify and Create demand in potential sectors<\/li>\n\n\n\n<li>Provide production incentives for setting up domestic capacity<\/li>\n\n\n\n<li>Achieve<strong> 5 million metric tonnes<\/strong> of green hydrogen production by 2030.<\/li>\n\n\n\n<li>Averting nearly <strong>50 MMT of CO2<\/strong> emissions annually.<\/li>\n\n\n\n<li>Attract investments of about <strong>USD 100 billion<\/strong>.<\/li>\n\n\n\n<li>Generate over 600,000 jobs.<\/li>\n\n\n\n<li><strong>The Green Hydrogen Certification Scheme <\/strong>is a framework established to ensure the transparent and credible certification of green hydrogen production in India.<\/li>\n\n\n\n<li><strong>Green Hydrogen and Green Ammonia plants<\/strong> have been exempted from Environmental Clearance by the Ministry of Environment, Forest and Climate Change.&nbsp;<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Progress&nbsp;<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The first batch of <strong>three hydrogen-powered heavy-duty trucks<\/strong> will operate on the <strong>Faridabad\u2013Delhi NCR<\/strong> and <strong>Ahmedabad\u2013Surat\u2013Vadodara routes<\/strong>.\n<ul class=\"wp-block-list\">\n<li>To support this transition, Indian Oil Corporation Limited (IOCL) is establishing <strong>hydrogen refueling stations <\/strong>in Faridabad, Vadodara, Pune, and Balasore.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Three major ports<\/strong> namely <strong>Kandla, Paradip and Tuticorin ports <\/strong>have been identified by the Ministry of Ports, Shipping and Waterways (MoPSW) to be developed as <strong>Green Hydrogen hubs.&nbsp;<\/strong><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Concluding remark<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>India\u2019s success in developing a solar-powered green hydrogen device signals the beginning of a transformative journey toward a decarbonised economy.&nbsp;<\/li>\n\n\n\n<li>However, translating scientific innovation into large-scale application will require coordinated efforts across policy, industry, and finance.<\/li>\n<\/ul>\n\n\n\n<p><strong>Source: <\/strong><a href=\"https:\/\/www.pib.gov.in\/PressReleasePage.aspx?PRID=2138051\" rel=\"nofollow noopener\"
