“…They showed that the fault breach occurred due to excessive injection in a confined space. Meanwhile, for safe disposal of CO2 and wastewater in saline aquifers or depleted reservoirs, the studies of Phan et al [49] and Gogri et al [50] offered practical guidelines for prognosis with real-time surveillance data.…”

In recent years, the oil and gas sector has been moving towards green production methods to achieve net-zero emission goals. Governments and corporations have started large-scale initiatives to deploy advanced technologies to reduce carbon footprints and prevent global warming. Herein, we have explored the emerging techniques and methods used in reducing the effects of gas emissions in the oil and gas industry. The transition process from hydrocarbons to renewable energy resources, including solar thermal applications for EOR, thermal energy extraction from hydrocarbon reservoirs, hydrogen generation strategies, and CO2 EOR and storage applications, has also been discussed. Literature information and publicly available data have paved the way to provide the theoretical background, the rationale of use, screening and selection criteria, challenges, and workarounds for these novel energy sources. Systems to integrate green methods into oil and gas processes appear in detail, from screening to implementation. Then, the technical information for integrating these resources under multiple conditions that affect the system's efficiency, such as weather, seasonal temperature changes, wind, and solar exposure, have been investigated. Moreover, added benefits of such incorporation strategies, such as improved economics with minimal effects on capital intensiveness or other burdens on the overall economy, have also been addressed. The transition from fossil fuels to renewable and greener energy resources provided the underlying motivation for this study.

“…As an alternative incentive, the prospect of generating secondary revenue or higher productivity, or reducing costs associated with the primary activities of an operator hosting CDR strategies, may entice financial commitment or reduce associated risks. Beyond carbon pricing incentives, there are limited co-benefits to in-situ approaches that could be realized, although there is a possibility to utilise wastewater as the injection solution (Phan et al, 2018), while the scale of operations could provide an employment transition from diminishing fossil fuels industries. Ex-situ methods likely afford several possible co-benefits, such as increased crop yields and plant growth associated with enhanced weathering and spreading in soils, as well as remediation of toxic metal contamination, reversal of soil acidification and replenishment of macro and micronutrients (Leonardos et al, 1987;Hartmann et al, 2013;Anda et al, 2015;Renforth et al, 2013;Beerling et al, 2018Beerling et al, , 2020Kelland et al, 2020;Buckingham et al, 2022).…”

Many nations have pledged to reduce carbon dioxide (CO2) emissions over the remainder of the century to meet the Paris Agreement targets of limiting warming to no more than 1.5&#176;C, aiming for net zero by mid-century. This is the long-term commitment of the European Union (EU), which is targeting climate-neutrality by 2050, in line with the commitment to global climate action under the Paris Agreement and the European Green Deal. For many European nations, this means a critical examination of all potential pathways to net zero (or net negative), including assessing methodological options, material suitability and physical footprints. To achieve national and EU reduction targets, there is a further need for CO2 removal (CDR) approaches on a scale of millions of tonnes, necessitating a better understanding of feasible methods and materials for utilization. One approach that is gaining attention is geochemical CDR, encompassing (1) in-situ injection of CO2-rich gases into Ca and Mg-rich rocks for geological storage by mineral carbonation, (2) ex-situ approaches such as ocean alkalinity enhancement and ocean liming, enhanced weathering and carbonation of alkaline-rich materials, and (3) electrochemical separation processes. In this study, we examine the geochemical CDR potential of Spain. As an EU Member State, Spain is bound to adopt the national energy and climate plans to make considerable progress on its climate actions. Here, an assessment of the reactivity potential of materials and utilization sites in Spain has been made based on the suitability of hosted materials in terms of spatial and volumetric availability, chemistry, modal mineralogies and mineral kinetics. Spain hosts a potentially high geochemical CDR capacity thanks to its varied geological settings and its high tonnage production of industrial alkaline wastes, suitable due to their high Ca and Mg contents and varying occurrence of kinetically favourable minerals (e.g., serpentine, brucite, olivine). There are notional kilotonne to million tonne scale CDR options for Spain over the rest of the century, with attention paid to mafic, ultramafic and carbonate rocks, mine tailings, fly ashes, slag by-products, desalination brines and ceramic wastes, with industrial, agricultural and coastal areas providing opportunities to launch pilot schemes. Materials and land space are distributed across the Spanish mainland and islands, with particularly high potential for Galicia, Andaluc&#237;a, Murcia and the Canary Islands regions. The CDR potential of Spain warrants dedicated investigations to achieve the highest possible CDR to make valuable contributions to national reduction targets. Results can also be used to further define Spain&#8217;s overall climate targets and initiate future CDR plans and projects for academia, industry, government and other sectors of interest. This work forms part of the DETAILS project (Developing enhanced weathering methods in mine tailings for CO2 sequestration; Marie Sk&#322;odowska-Curie grant agreement ID: 101018312).

“…In situ mineralization may have fewer adverse environmental and human health effects than surface-based geochemical NETs, since materials are mostly contained beneath the Earth's surface where they have little direct impact on ecosystems and biodiversity, and typically use less land and fresh water than other NETs (National Academies of Sciences, Engineering, and Medicine, 2019). Wastewater could be co-injected with CO 2 for dual benefit (Phan et al, 2018). In situ mineralization could have other potential co-benefits, such as enabling the transition of workers from fossil fuel industries into the clean energy sector where near-identical skills are required.…”

Geochemical Negative Emissions Technologies: Part I. Review

Over the previous two decades, a diverse array of geochemical negative emissions technologies (NETs) have been proposed, which use alkaline minerals for removing and permanently storing atmospheric carbon dioxide (CO2). Geochemical NETs include CO2 mineralization (methods which react alkaline minerals with CO2, producing solid carbonate minerals), enhanced weathering (dispersing alkaline minerals in the environment for CO2 drawdown) and ocean alkalinity enhancement (manipulation of ocean chemistry to remove CO2 from air as dissolved inorganic carbon). CO2 mineralization approaches include in situ (CO2 reacts with alkaline minerals in the Earth's subsurface), surficial (high surface area alkaline minerals found at the Earth's surface are reacted with air or CO2-bearing fluids), and ex situ (high surface area alkaline minerals are transported to sites of concentrated CO2 production). Geochemical NETS may also include an approach to direct air capture (DAC) that harnesses surficial mineralization reactions to remove CO2 from air, and produce concentrated CO2. Overall, these technologies are at an early stage of development with just a few subjected to field trials. In Part I of this work we have reviewed the current state of geochemical NETs, highlighting key features (mineral resources; processes; kinetics; storage durability; synergies with other NETs such as DAC, risks; limitations; co-benefits, environmental impacts and life-cycle assessment). The role of organisms and biological mechanisms in enhancing geochemical NETs is also explored. In Part II, a roadmap is presented to help catalyze the research, development, and deployment of geochemical NETs at the gigaton scale over the coming decades.
