The cost and carbon intensity (CI) of renewable hydrogen production exhibit significant regional variability, driven by disparities in renewable energy resources, according to a comprehensive geospatial techno-economic analysis. The study, which evaluates solar and wind-based hydrogen production across diverse locations, identifies optimal regions where low-cost, low-carbon hydrogen can be produced efficiently. For instance, areas with high solar irradiance or consistent wind speeds demonstrate lower production costs and reduced CI compared to regions with less favorable renewable energy conditions.

Life cycle assessments (LCAs) further reveal the environmental trade-offs associated with different hydrogen production methods. Electrolysis powered by renewable electricity emerges as the most sustainable option, but its viability hinges on the local availability of solar or wind energy. The analysis also highlights the importance of infrastructure, such as water availability for electrolysis, which can further influence regional feasibility.

Industry experts emphasize the implications of these findings for policymakers and investors. "Location-specific strategies are critical to unlocking the full potential of renewable hydrogen," said Dr. Elena Rodriguez, a lead researcher on the project. "Targeted investments in regions with abundant renewable resources can accelerate cost reductions and decarbonization."

The study provides a framework for identifying high-potential hydrogen hubs, offering a roadmap for scaling up production while minimizing environmental impacts. As global demand for clean hydrogen grows, these insights could shape national and international energy policies, ensuring that renewable hydrogen plays a pivotal role in the transition to a low-carbon economy.
