Global hydrogen energy technology and resource developments

Developments in the hydrogen energy sector are advancing through technological innovation, resource exploration, and sustainable synthesis research.

Technological progress includes the delivery of a 0.5 MW Anion Exchange Membrane (AEM) electrolyzer from the US to Belgium, designed to integrate with renewable power while avoiding scarce materials. Concurrently, global interest in geologic hydrogen is rising, with researchers in China reporting high-purity hydrogen seepage in the Sichuan Basin and potential extraction hotspots identified in the Philippines. This follows estimates from the U.S. Department of Energy regarding vast global natural hydrogen deposits.

Research is also expanding into alternative production and storage methods. In Colombia, studies have simulated using sugarcane bagasse for hydrogen production via thermochemical conversion, though economic evaluations suggest current lack of profitability. In Chile, efforts are focused on the electrochemical synthesis of green ammonia using Protonic Ceramic Electrochemical Cells (PCECs) to provide a more efficient alternative to the traditional Haber-Bosch process.
