Such storage will require large-scale injection of CO 2 into subsurface saline aquifers and depleted hydrocarbon reservoirs (e.g. Ringrose and Meckel, 2019; Ringrose et al., 2021).
The large-scale injection of carbon dioxide (CO 2) into saline aquifers is a promising tool for reducing atmospheric CO 2 emissions to mitigate climate change. An accurate assessment of the post-injection migration and trapping of the buoyant plume of CO 2 is essential for estimates of storage capacity and security, but these physical …
CO2 geological storage combined with deep saline water recovery technology (CO2-EWR) is one of the most effective ways to reduce carbon emissions. Due to the complex structural features, it is difficult to use CO2-EWR technology in Huaiyin Sag, Subei basin, East China. In this study, the multi-source information superposition …
Our results show that PM-CAES is a potentially viable large-scale inter-seasonal electricity storage technology, crucial in power systems with over 80% of their generation capacity provided by...
Fig. 1 shows schematically the large-scale subsurface impacts that may be experienced during and after industrial-scale injection of CO 2.While the CO 2 plume at depth may be safely trapped under a low-permeability caprock with an anticlinal structure, the footprint area of the plume is much smaller than the footprint area of elevated …
This UK storage potential is achievable at costs in the range US$0.42–4.71 kWh−1. Compressed-air energy storage could be a useful inter-seasonal storage resource to support highly renewable power systems. This study presents a modelling approach to assess the potential for such storage in porous rocks and, applying it to the UK, finds ...
Inter-seasonal compressed-air energy storage using saline aquifers. Meeting inter-seasonal fluctuations in electricity production or demand in a system dominated by renewable energy requires the cheap, reliable and accessible storage of energy on a scale that is currently challenging to achieve. Commercially mature compressed-air energy …
formations with suitable thickness and extent. For the decarbonisation of entire energy sectors and regions, large-scale storage in porous media, such as depleted gas fields and saline aquifers, is considered more promising (Heinemann et al., 2021).
The large-scale subsurface storage of hydrogen is a crucial element of the hydrogen economy value chain and is an essential process for achieving the successful replacement of carbon-based fuels. The wettability of the rock-H 2-brine system, as quantified by contact angle measurement, has been the focus of most recent research due to its impacts on …
Deep saline aquifers offer the largest storage potential of all the geological CO 2 storage options and are widely distributed throughout the globe in all sedimentary basins. For CO 2 storage to have a significant impact on atmospheric levels of greenhouse gases, the amounts of CO 2 injected and sequestered underground need to be extremely …

For storage over longer periods of time (months), for example to supply energy to domestic homes during the winter season, porous saline aquifers and depleted hydrocarbon fields …
Selecting suitable storage sites is the key to successfully implementing large-scale hydrogen storage in saline aquifers. Extensive research and demonstration …
As renewable fuel sources are intermittent and location-specific, large-scale, long-term storage options for H 2 must be explored with high necessity. …
Saline aquifers have been considered as sites with the highest potential for CO 2 storage because of their enormous capacity of roughly 1000–10,000 Gt of CO 2, which is 99% of possible storage capacity in the world (IPCC, 2005, Michael et al., 2010, White et).
Surface-based hydrogen storage facilities, such as pipelines and tanks, have limited storage and discharge capacities (MW h, hours–days); subsurface hydrogen …
