The Spanish gas transmission system operator, Enagas, has unveiled its ambitious plans for the development of renewable hydrogen infrastructure in Spain. The company intends to invest €4.035 billion through 2030, with a significant portion of €3.125 billion earmarked for this purpose. Enagas has completed the conceptual design for the Spanish Hydrogen Backbone and has secured funding from the Connecting Europe Facility, with plans to finalize the investment decision by the end of 2027. Additionally, the company has presented extensions for the Backbone, which would add 1,480 km of hydrogen pipelines post-2030, requiring an estimated investment of €2.135 billion. Enagas has also established a subsidiary, Scale Green Energy, dedicated to decarbonisation projects such as CO2 and LNG bunkering, renewable hydrogen for mobility, and green ammonia. The subsidiary will focus on developing various infrastructure like pipelines, liquefaction terminals, and CO2 transport vessels. Enagas foresees its gas infrastructures continuing to be vital, particularly in supporting electricity demand stability amid renewable energy variability, the nuclear phase-out, and increasing data center consumption.
