The report outlines a strategic roadmap for establishing a 'Green Hydrogen Valley' in Kochi, India, spearheaded by mec+ in collaboration with GIZ, the Indo German Energy Forum, and the International Hydrogen Ramp-Up Program. By adopting a 'two-way approach,' the study delved into the global hydrogen landscape to draw insights from successful hydrogen valleys worldwide. These insights were then meticulously overlaid with a profound understanding of Kochi's industrial and economic fabric. The research involved engaging with a diverse set of stakeholders in Kerala, reflecting industries, mobility firms, ports, infrastructure companies, technology providers, associations, and government bodies. The collaborative efforts culminated in the identification and exploration of opportunities that could pave the way for a thriving green hydrogen ecosystem in Kochi. The initiative is set to position Kochi as a frontrunner in green hydrogen production, incorporating principles of sustainability, clean energy utilization, and technological innovation. The comprehensive roadmap aims to leverage the synergies of a robust local industrial base and global best practices in hydrogen technology to propel Kochi into a prominent player in the realm of green hydrogen production and utilization.
