The article delves into the innovative world of green hydrogen production through electrolysis, shedding light on its numerous benefits and potential as a sustainable energy alternative. Green hydrogen is showcased as a versatile 'Swiss army knife of molecules,' capable of serving various purposes like fuel, energy storage, and agricultural applications such as fertilizer production. Vertige, a company specializing in alkaline water electrolysis, is at the forefront of making green hydrogen more economically viable by focusing on reducing the costs associated with electrolysis equipment and achieving grid parity in select regions. They have developed a 20-megawatt electrolyzer that can produce over 8000 kg of hydrogen daily, with plans to scale up production through multiple electrolyzers in large-scale plants. The company aims to reach fossil parity before 2030, making green hydrogen more cost-effective than fossil fuels on a global scale when produced efficiently at a large scale. The article highlights the efficiency and adaptability of Vertige's electrolyzers, their cost competitiveness, and the potential for large-scale adoption of green hydrogen in the near future.
