Oman unveiled one of the world’s most ambitious ever renewable energy schemes, with plans to build 25GW of wind and solar to turn the Middle East state into a global hub for green hydrogen.

A consortium of Oman’s state energy company OQ, developer InterContinental Energy and Kuwait-based Enertech said the vast renewable capacity would “produce millions of tonnes of zero-carbon green hydrogen per annum” for local use, export or conversion into green ammonia.
