Abstract

The quest for a carbon–neutral energy future has positioned hydrogen as a pivotal player in global-sustainability eff orts. This

comprehensive review examines the transformative role of hydrogen in revolutionizing sustainable energy consumption.

Hydrogen’s high energy density, versatility, and minimal ecological footprint make it ideal for stabilizing the intermittent

nature of renewable energy sources. This study evaluates the latest advancements in hydrogen production technologies,

including advanced electrolysis, reforming strategies, and biologic processes, assessing their operational effi ciencies and

environmental impacts. In addition, it explores the strategic deployment of hydrogen in transportation, industrial processes,

and electricity sectors, highlighting its potential to signifi cantly reduce fossil-fuel dependence and mitigate climate change.

The economic considerations and policy imperatives crucial for the global adoption and scaling of hydrogen storage systems

are also discussed. This review underscores hydrogen’s critical role in creating an eco-effi cient and resilient energy

infrastructure, advocating for an accelerated transition to hydrogen-based solutions to achieve a cleaner, greener planet.
