In an email interaction with Chemical Industry Digest, Vaithyanathan Nagarajan (Vaidya), Managing Director of thyssenkrupp nucera India Pvt. Ltd, discussed the company's foray into the green hydrogen business. With over 50 years of experience in electrolysis technology, thyssenkrupp nucera aims to enable energy transition by delivering innovative products for green hydrogen production. Their high-efficiency standardized electrolyzer unit, scalum®, optimizes energy usage and space requirements, making green hydrogen production more cost-competitive. The company plans to increase production to 5GW, emphasizing the importance of large-scale electrolyzer plants for cost efficiency. Transporting green hydrogen poses challenges like infrastructure development, efficiency losses, and costs. Thyssenkrupp nucera suggests using green ammonia and green methanol as substitutes due to their higher energy densities and transport feasibility. However, upgrades in transport infrastructure and safety considerations are essential for their adoption. In India's energy-intensive Chlor-Alkali sector, the company ensures cost competitiveness through advanced technologies that optimize energy usage, operational efficiencies, and strategic sourcing. Thyssenkrupp nucera also offers Chlor-Alkali manufacturing in standardized models and modular/skid-mounted units. Standardized models drive cost-effectiveness in large-scale projects, while modular units provide flexibility for customers to upgrade to the latest developments in electrolysis technology. The company's focus on sustainability, energy efficiency, and cost competitiveness positions them as a key player in promoting green hydrogen and decarbonization in industries.
