Aldar is the first developer in the MENA region to incorporate hydrogen-based steel rebar into a construction project. In Sustainable City, Yas Island, the company is building the first Net Zero carbon mosque.
The use of green steel is central to the mosque’s bid for LEED Zero Carbon certification, a first for Abu Dhabi, which Emsteel said would set a new benchmark in sustainable architecture.
“This landmark delivery reinforces Emsteel’s commitment to driving industrial sustainability and accelerating the UAE’s transition to a low-carbon economy,” explained Saeed Ghumran Al Remeithi, Group CEO at Emsteel.
While it’s not clear how much was delivered, the rebar was produced using hydrogen from Emsteel’s green hydrogen pilot project it launched with Masdar in 2024.
The mosque delivery marks the first commercial use of the pilot’s output, certified to ISO standards by Avance Labs and independently verified by Bureau Veritas.
“In collaboration with Aldar, Emsteel is setting a powerful precedent for the adoption of green steel across future residential, commercial, and public infrastructure projects,” added the CEO.
While green hydrogen shows strong potential to replace grey hydrogen in existing industrial feedstocks, its use in steelmaking remains at a very early stage globally.
The cost and infrastructure barriers in the sector are expected to delay widespread adoption until the 2030s, according to IDTechEx.
