UC Chile Develops Activated Carbon-Based Green Hydrogen Storage for Residential Use
Key Insights
Researchers at UC Chile have developed an activated carbon-based system for storing green hydrogen, making it feasible for residential applications.
The breakthrough could significantly reduce the cost and complexity of hydrogen storage, addressing a key barrier to widespread adoption.
The technology leverages porous activated carbon to safely store hydrogen at lower pressures, enhancing safety and efficiency.
This innovation aligns with global efforts to decarbonize residential energy use and integrate hydrogen into everyday energy systems.
Researchers at the University of Chile (UC Chile) have unveiled a groundbreaking activated carbon-based system for storing green hydrogen, potentially bringing this clean energy carrier into residential use. The development, announced on June 27, 2025, addresses one of the most significant challenges in hydrogen adoption: safe and cost-effective storage.
The technology utilizes porous activated carbon to absorb hydrogen at lower pressures compared to conventional high-pressure tanks or cryogenic storage. This method not only reduces the risk of leaks and explosions but also lowers the energy required for compression, making the system more efficient and economical. According to the research team, the activated carbon material can store hydrogen at near-ambient temperatures, further simplifying infrastructure requirements.
"This is a game-changer for residential hydrogen applications," said Dr. Maria Fernandez, lead researcher at UC Chile. "By eliminating the need for high-pressure tanks, we can integrate hydrogen storage seamlessly into homes, much like natural gas systems today."
The innovation comes as governments and industries worldwide push for hydrogen as a key component of decarbonization strategies. Green hydrogen, produced using renewable energy, is particularly attractive for its zero-emission potential. However, storage and transportation costs have hindered its scalability. The UC Chile solution could bridge this gap, especially in regions where renewable energy is abundant but storage solutions are lacking.
Market analysts suggest that the technology could accelerate the adoption of hydrogen in residential heating, cooking, and backup power systems. Pilot projects are already underway in Chile, with plans to expand to other markets in Latin America and Europe. The research team is also exploring partnerships with energy companies to commercialize the technology by 2026.
This development aligns with global trends, such as the European Union's Hydrogen Strategy, which aims to integrate hydrogen into 20% of residential energy use by 2030. With further refinements, the UC Chile system could become a cornerstone of the emerging hydrogen economy.
