“…BECCS using dedicated bioenergy crops could substantially increase agricultural water demand (Bonsch et al, 2014;Séférian et al, 2018) and nitrogen fertilizer use (Bodirsky et al, 2014). DACCS and BECCS rely on CCS and would require safe storage space in geological formations, including management of leakage risks (Pawar et al, 2015) and induced seismicity (Nicol et al, 2013). Some approaches like DACCS have high energy demand (Socolow et al, 2011).…”

“…Induced seismicity due to fluid removal and reinjection has continued for over a hundred years, although analysis of earthquakes in California and Oklahoma indicates that the mechanisms have varied with industry practices [9,10]. The geological sequestration of CO 2 , which is a critical component of any climate management strategy, may [80] (or may not [81]) result in significant changes in seismicity rates around storage sites.…”

Earthquakes can influence flood hazards by altering the flux, volumes, and distributions of surface and/or subsurface waters and causing physical changes to natural and engineered environments (e.g., elevation, topographic relief, permeability) that affect surface and subsurface hydrologic regimes. This paper analyzes how earthquakes increased flood hazards in Christchurch, New Zealand, using empirical observations and seismological data. Between 4 September 2010 and 4 December 2017, this region hosted one moment magnitude (Mw) 7.1 earthquake, 3 earthquakes with Mw ≥ 6, and 31 earthquakes with local magnitude (ML) ≥ 5. Flooding related to liquefaction-induced groundwater pore-water fluid pressure perturbations and groundwater expulsion occurred in at least six earthquakes. Flooding related to shaking-induced ground deformations (e.g., subsidence) occurred in at least four earthquakes. Flooding related to tectonic deformations of the land surface (fault surface rupture and/or folding) occurred in at least two earthquakes. At least eight earthquakes caused damage to surface (e.g., buildings, bridges, roads) and subsurface (e.g., pipelines) infrastructure in areas of liquefaction and/or flooding. Severe liquefaction and associated groundwater-expulsion flooding in vulnerable sediments occurred at peak ground accelerations as low as 0.15 to 0.18 g (proportion of gravity). Expected return times of liquefaction-induced flooding in vulnerable sediments were estimated to be 100 to 500 years using the Christchurch seismic hazard curve, which is consistent with emerging evidence from paleo-liquefaction studies. Liquefaction-induced subsidence of 100 to 250 mm was estimated for 100-year peak ground acceleration return periods in parts of Christchurch.

“…While leakage through seal permeability (fluid flow) and seal integrity (fracturing) can be assessed empirically, and leakage via unsound infrastructure can be mitigated with some certainty, leakage up fault zones is more difficult to assess, mainly because of their heterogeneity. 31,32 The magnitude and extent of a pressure front depends on the rate of injection versus the effective permeability of the reservoir, and how readily the pressure can be transmitted. Pressure relief wells 33 that withdraw formation water create a zone of reduced pressure that can allow more rapid injection nearby, guide the direction of movement of the injected material, or potentially eliminate a pressure front entirely.…”

Subsurface resources include oil, gas, coal, groundwater, saline aquifer minerals, and heat (for geothermal use). Pore space itself should also be considered as a resource as it can be used for injection of waste fluids, produced water, storage of natural gas, compressed air, and supercritical CO 2. Use of subsurface resources can overlap in space, and pressure changes at one site can remotely influence resource use at other sites. Resource use can also vary in time, such as the use of depleted oil or gas fields for natural gas or CO 2 storage. Before allocation of a subsurface resource it is therefore useful to understand the potentially wide range of resources available in an area, how they might be developed successively, and how they could affect each other if used concurrently. While these issues are primarily geological, they have critical significance for legal, environmental, and economic considerations.
