India's transition to a low-carbon economy is gaining momentum, with green hydrogen emerging as a pivotal element in achieving net-zero emissions by 2070. Green hydrogen, produced via electrolysis using renewable energy sources, offers a versatile, zero-emission alternative for hard-to-abate sectors such as steel, fertilizers, refining, and transportation. At the national level, the Government of India launched the National Green Hydrogen Mission (NGHM) in January 2023, setti

Electrolyzers are critical for green hydrogen production, splitting water into hydrogen and oxygen via electricity from renewables. As of early 2026, the global market is dominated by alkaline (AWE) and proton exchange membrane (PEM) technologies, with anion exchange membrane (AEM) and solid oxide electrolysis cells (SOEC) emerging. Key efficiencies (based on higher heating value, HHV, system level) vary: AWE (~65-75%, mature and cost-effective for large-scale), PEM (~60-70%,

Green hydrogen, produced via electrolysis using renewable energy, requires efficient storage to address its low density and intermittency challenges. As of 2026, storage methods have advanced significantly, focusing on scalability, safety, and cost reduction to support global decarbonization. Key technologies balance energy density, efficiency, and infrastructure compatibility, with innovations driven by materials science and AI. Below, we outline the primary methods, includi

Green hydrogen, produced through the electrolysis of water using renewable energy sources like solar or wind, represents a cornerstone of the global energy transition. Unlike "grey" hydrogen derived from fossil fuels, green hydrogen emits no carbon dioxide during production, making it a vital tool for decarbonizing hard-to-abate sectors such as heavy industry, transportation, and power generation. As of January 2026, the sector is at a pivotal juncture. After years of hype an

In 2026, green hydrogen—produced through electrolysis using renewable energy sources like solar and wind—stands at the forefront of the energy transition. As nations strive for net-zero emissions, these projects represent massive investments in clean fuel production, often aimed at exporting hydrogen or derivatives like green ammonia for industrial use, transportation, and power generation. Drawing from recent industry reports and databases, here are the top 10 largest green
