“…Storage projects expect a risk profile that decreases steadily during site planning, operation, and closure (de Coninck & Benson, 2014). If anomalies are observed, such as gas detected at the ground surface or seafloor, or unexpectedly rapid plume migration, a new evaluation of risks will determine if an operational change is needed (Dean et al, 2020;Waage et al, 2021;Glubokovskikh et al, 2020).…”

Limiting climate change to less than 1.5 o C would require vast quantities of CO2 storage in subsurface geological formations. Global injection rates projected by integrated assessment models synthesised in IPCC reports are on the order of ten gigatonnes per year by 2050. Industrial experience with megatonne per year storage projects allows us to evaluate the feasibility and potential limitations of a transition to the gigatonne scale. The successes with CO2 have also led to interest in new energy technologies using subsurface fluids, including hydrogen storage underground. We review the role of subsurface CO2 and H2 storage in a sustainable energy transition. We have found that current deployment demonstrates the viability of CO2 storage in a variety of geological, social, economic, and technological contexts, and is making contributions to climate change mitigation today commensurate with the impact of solar photovoltaics in the USA market. The implications of this are that CO2 storage is well positioned to play an important role in the energy transition, and H2 storage may benefit from this experience. However, these are not certain outcomes, with many hurdles -the development of multi-site regional scale storage, viable business models for accelerated deployment, demonstrating environmental sustainability and achieving societal acceptability -yet to be addressed.

“…This observation might affect the identification and interpretation of seal bypass systems with dimensions below seismic resolution, which can even be more effective bypass structures than their larger scale seismic chimneys analogues (Cartwright et al, 2007). In this regard, Waage et al (2021) found that detectable geophysical signatures of partial CO2 saturation structures using high-resolution P-Cable 4D seismic method (with f = 500 Hz), highly depends on the pore fluid distribution, with a low detection limit of SCO2 ~3% for uniform distribution but up to ~27% if patchy. This SCO2-patchy value is in agreement with our experimental observations, Amalokwu et al (2017) andFalcon-Suarez et al (2020b) for sandstones with oriented fractures at ultrasonic frequencies, and can be expected above 200 Hz according to the modelling results reported by Solazzi et al (2020) if just considering the hypothesis of CO2-induced sub-vertical fractures.…”

Submarine landslides pose a hazard to coastal communities due to the tsunamis they can generate, and can damage critical seafloor infrastructure, such as the network of cables that underpin global data transfer and communications. These mass movements can be orders of magnitude larger than their onshore equivalents and are found on all of the world’s continental margins; from coastal zones to hadal trenches. Despite their prevalence, and importance to society, offshore monitoring studies have been limited by the largely unpredictable occurrence of submarine landslide and the need to cover large regions of extensive continental margins. Recent subsea monitoring has provided new insights into the preconditioning and run-out of submarine landslides using active geophysical techniques, but these tools only measure a very small spatial footprint, and are power and memory intensive, thus limiting long duration monitoring campaigns. Most landslide events therefore remain entirely unrecorded. Here we first show how passive acoustic and seismologic techniques can record acoustic emissions and ground motions created by terrestrial landslides. We then show how this terrestrial-focused research has catalysed advances in the detection and characterisation of submarine landslides, using both onshore and offshore networks of broadband seismometers, hydrophones and geophones. We then discuss some of the new insights into submarine landslide preconditioning, timing, location, velocity and their down-slope evolution that is arising from these advances. We finally outline some of the outstanding challenges, in particular emphasising the need for calibration of seismic and acoustic signals generated by submarine landslides and their run-out. Once confidence can be enhanced in submarine landslide signal detection and interpretation, passive seismic and acoustic sensing has strong potential to enable more complete hazard catalogues to be built, and opens the door to emerging techniques (such as fibre-optic sensing), to fill key, but outstanding, knowledge gaps concerning these important underwater phenomena.
