Paper presented at the Abu Dhabi International Petroleum Exhibition & Conference, November 9–12, 2020
Paper Number: SPE-202984-MS
... Abstract Approximately 40% of current global natural gas resources have high H 2 S and CO 2 concentrations. The H 2 S concentration in Middle East gas reservoirs can potentially reach up to 30 mol%. H 2 S is toxic; therefore, the produced natural gas must be treated and sweetened. In this high...

... methods release CO 2 as a side product and are thus carbon-intensive. A zero-carbon approach of producing hydrogen can be achieved via electrolysis of water powered by surplus renewable energy sources, which in return helps to balance the intermittency of solar photovoltaic (PV) or wind. Hydrogen is also...
