Gulf Cooperation Council states are positioning themselves as leaders in the emerging hydrogen economy, leveraging their advantages in solar power generation, industrial capacity, and storage options for carbon sequestration. With ambitious projects like Saudi Arabia's NEOM megaproject, the region aims to generate significant revenues from green hydrogen by 2050. Hydrogen diplomacy is growing, with GCC states building relations with Asian markets, particularly China, Japan, and South Korea. The development of hydrogen infrastructure, including tanker-based transportation, is key to maintaining the Gulf's status as a major energy producer and exporter, while also reflecting new geopolitical dynamics.
