The article discusses the urgent need to reduce greenhouse gas emissions in heavy industries to meet the global climate goals outlined in the Paris Agreement. Despite progress in renewable energy, many industries still heavily rely on fossil-based hydrogen, contributing to global carbon emissions. To address this, the shift to green hydrogen, generated through renewable electricity and water electrolysis, is crucial. Ohmium, a prominent electrolyser manufacturer, has developed innovative PEM electrolysis technology that significantly reduces costs and boosts efficiency. Their hyper-modular design streamlines deployment and enhances scalability, supporting the rapid adoption of green hydrogen solutions. The article also highlights a collaborative pilot project in New Delhi where Ohmium's PEM electrolyser technology is utilized to generate green hydrogen from a solar array, demonstrating the practical application of green hydrogen in power generation.
