In a new Nature Communications study, researchers propose a new method for hydrogen storage using existing pipes located at the bottom of lakes and reservoirs.

Hydrogen has surfaced as a promising alternative to fossil fuels for energy generation in several industries. The focus is especially on green hydrogen, which is produced via electrolysis of water using renewable energy sources like solar, wind, and air.

Nonetheless, the broad adoption of green hydrogen has faced challenges, primarily due to a lack of adequate storage solutions.

This study recommends the use of high-density polyethylene (HDPE) pipes as a means of storing green hydrogen. HDPE pipes are used at the bottom of lakes, reservoirs, or hydropower storage systems for water management.

Phys.org spoke to the study's first author, Dr. Julian David Hunt, a Research Scientist at the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia.
