Green hydrogen has long been heralded as a revolutionary clean energy technology, particularly for challenging sectors like transportation, steel production, and shipping. Despite its potential, the anticipated surge in green hydrogen usage has been hindered by high production costs and inefficiencies compared to direct clean energy use.
Combustible at high temperatures and emitting only water vapor, hydrogen presents an attractive option for industries requiring intense heat. Unlike solar or wind power, green hydrogen offers a reliable and storable energy source, enhancing flexibility and resilience.
The cost factor remains a significant hurdle for green hydrogen, which is produced from renewable sources, unlike gray hydrogen made from fossil fuels, or blue hydrogen derived from natural gas. Historically, green hydrogen has been priced at three to five times the cost of its gray counterpart.
Globally, the transition to green hydrogen has faced a disconnect between ambitious plans and their execution. As of 2023, less than 10% of planned projects had reached completion. A 2025 study tracking 190 projects over three years highlighted that only 7% of global capacity announcements met their schedule.
Nevertheless, the landscape for green hydrogen could shift by 2026. Continued research has led to breakthroughs, indicating that green hydrogen remains viable. A notable advancement involves a system utilizing waste materials in production, which has been successful in producing hydrogen at costs lower than fossil fuels, as reported by Interesting Engineering.
This innovative system, developed by China Agricultural University and Nanyang Technological University, uses sugars from agricultural waste, reducing production costs to $1.54 per kilogram. The study published in eScience details an efficient process where glucose is converted to formate, avoiding the need for costly separation membranes and lowering energy requirements.
The implications of this breakthrough are substantial. According to Interesting Engineering, it might end the economic impasse between clean energy and natural gas. However, the newfound affordability of green hydrogen doesn’t automatically position it as the optimal energy solution.
The International Renewable Energy Agency (IRENA) cautioned in a 2022 report against widespread hydrogen use without strategic planning. They emphasized that green hydrogen requires dedicated renewable energy, which might be better allocated to other uses in a decarbonized world.
