Assessing Natural Gas Versus CO2 Potential Underground Storage Sites in Greece: A Pragmatic Approach †

Although subsurface traps have been regularly explored for hydrocarbon exploration, natural gas and CO2 storage has drawn industrial attention over the past few decades, thanks to the increasing demand for energy resources and the need for greenhouse gas mitigation. With only one depleted hydrocarbon field in Greece, saline aquifers, salt caverns and sedimentary basins ought to be evaluated in furtherance of the latter. Within this study the potential of the Greek subsurface for underground storage is discussed. An overview and re-evaluation of the so-far studied areas is implemented based on the available data. Lastly, a pragmatic approach for the storage potential in Greece was created, delineating gaps and risks in the already proposed sites. Based on the above details, a case study for CO2 storage is presented, which is relevant to the West Katakolo field saline aquifer.

Natural gas storages in salt caverns are receiving an increasingly important role in energy storage system of many countries. This study focuses on analyzing the consequence of jet fire associated with natural gas storages in salt caverns. A widely used software, ALOHA, was adopted as simulation tool. The reliability of ALOHA was validated by comparing the simulated results with the field data observed in real accidents and the values calculated by a simple model presented in a previous study. The China's first natural gas storage in salt cavern, Jintan natural gas storage, was selected for case study. The case study reveals that the hazard distance of jet fire decreased with the increase of pipeline length, as well as the decrease of pipeline diameter and operating pressure.

Abstract Over the last decade, there has been an irreversible shift from hydrocarbon exploration towards carbon storage, low-carbon energy generation and hydrogen exploration. Whilst basin modelling techniques may be used to predict the migration of hydrocarbons through sedimentary basins on geological timescales, there remains little understanding of how fluids behave at the basin scale on present-day timescales. Maximum vertical fluid velocity, vmax, may be calculated as the product of mobility and buoyancy. We present am algorithm to determine the basin-scale mobilities of CO2 and methane with depth for sandstone and carbonate. CO2 and methane mobility and buoyancy increase by an order of magnitude at gas phase transitions and are significantly greater in sandstone than in carbonate. Critical properties of CO2 cause fluid mobility and buoyancy to be sensitive to changes in surface temperature. vmax for CO2 and methane are on scales of m/year. Our results indicate an optimal depth for CO2 storage of below 0.59 km and 1.24 km when surface temperature > 20oC and 0oC, respectively. vmax for hydrogen is approximately 2-10 times greater than other hydrocarbon fluids and this will have important consequences for the future use of basin modelling software for determining hydrogen migration for exploration and storage.

This article examines the claim that Israel’s natural gas exports from its Mediterranean gas fields will give geopolitical leverage to Tel Aviv over the importing countries. Using the geoeconomic tradition of Klaus Knorr and others who wrote about applying leverage using economic resources to gain geopolitical advantage, it is argued that certain criteria have to be satisfied for economic influence attempts, and that Israel’s gas exports do not satisfy these criteria. They include the importer’s supply vulnerability, the supplier’s demand vulnerability, and the salience of energy as an issue between both countries. Israeli gas exports to Egypt are used as a case study.
