Saudi Aramco has entered into an agreement with US-based Air Products to develop the world's first hydrogen refuelling station in Saudi Arabia amid a push to look at cleaner investment opportunities in the kingdom. The refueling station is expected to be operational in 2Q19 and will be located within the Dhahran Techno Valley Science Park, the company said in a statement. Saudi Aramco and Air Products are set to establish a pilot fleet of fuel cell vehicles that run on high-purity compressed hydroden dispensed at the new fuelling station, the company said.
