Hydrogen has emerged as a key component in the global transition towards low-carbon energy systems. Acknowledged for its potential to drive sustainability, clean hydrogen is hailed as a promising solution capable of decarbonizing challenging sectors, facilitating the integration of renewable energy through robust energy storage mechanisms, and enhancing energy security. However, the current landscape reveals that clean hydrogen occupies only a marginal share in the broader hydrogen market, due to a constellation of challenges, including high costs, intricate technical barriers, and a lack of standardized protocols. Nonetheless, several governments across the world have unveiled comprehensive plans and funding initiatives intended to catalyze transformative progress in clean hydrogen technology by the end of this decade.
