hydrogenrelated

Hydrogenrelated refers to topics, technologies, and research connected to hydrogen, the lightest element and a versatile energy carrier. The term covers production, storage, distribution, conversion, and end use of hydrogen as a fuel, chemical feedstock, or energy-storage medium. Hydrogenrelated work spans chemistry, materials science, and energy systems and is central to efforts to decarbonize industry, transportation, and power generation.

Production methods vary in carbon intensity. Electrolysis using renewable or low-emission electricity yields green hydrogen, while steam methane reforming remains prevalent with carbon capture (blue hydrogen) or without (grey hydrogen). Other routes include coal gasification and solar thermochemical splitting. Storage and transport pose technical challenges due to hydrogen's low density, diffusion, and material compatibility; common approaches include high-pressure compression, liquefaction, and chemical or solid-state carriers such as ammonia or metal hydrides.

Applications encompass fuel cells for vehicles and stationary power, industrial hydrogenation, refining and chemical synthesis, and large-scale energy storage to balance variable renewables. Infrastructure, cost, and purity requirements influence adoption. Safety concerns include flammability, leakage, and metal embrittlement, prompting codes, leak detection, and standards for handling and transport. Environmental impact depends on electricity sources and process efficiency; green hydrogen offers decarbonization potential but requires scalable, reliable systems and policy support.
