Integrated Assessment Models must better constrain CO2 geological storage projections Open
The availability of large-scale CO2 Geological Storage (CGS) strongly influences the feasibility and costs of ambitious climate pathways in Integrated Assessment Models (IAMs). IAMs describe transformation pathways across energy, land-use,…

Screening of mine shafts for future energy technologies: a case study from the Scottish coalfields Open
Abandoned mine shafts could be retrofitted for future energy technologies. We provide a high-level assessment of the potential for recorded mine shafts in the Scottish coalfields to be utilized for seven future technologies: geothermal hea…

Rapid Large-scale Trapping of CO2 via Dissolution in US Natural CO2 Reservoirs Open
Naturally occurring CO2 reservoirs across the USA are critical natural analogues of long-term CO2 storage in the subsurface over geological timescales and provide valuable insights into the fate of CO2 in the subsurface (Fig. 1). Previous …

National climate strategies show inequalities in global development of carbon dioxide geological storage Open
Carbon dioxide geological storage (CGS) is considered critical for limiting global average temperature rise to below 1.5 °C by mitigating fossil industrial emissions and delivering permanent Carbon Dioxide Removals. Here we examine the rol…

Constraining O isotope equilibrium exchange between CO2 and water during fluid cycling in a closed system Open
Residual trapping is a critical component of secure geological CO2 storage. Quantification of the amount of CO2 residually trapped plays a key role in predicting CO2 plume migration, immobilisation and storage security. However, it is diff…

National climate strategies show inequalities in global development of geological storage of CO2 Open
CO2 geological storage (CGS) is considered critical for limiting global average temperature rise to below 1.5°C by mitigating fossil industrial emissions and delivering permanent carbon dioxide removals. We examine the role of CGS in long-…

Comparing fluid flow mechanisms in reservoir rocks to improve subsurface pollutant remediation Open
In order to reach carbon neutrality, a drastic increase in subsurface carbon storage is essential. During the storge site selection process, sites are assessed based on overall security for long-term storage, and any remaining risks requir…

Reconstructing the temperature and origin of CO2 mineralisation in CarbFix calcite using clumped, carbon and oxygen isotopes Open
In-situ CO2 mineralisation has been demonstrated as a rapid and secure mechanism of geological CO2 storage through a series of field demonstrations in Icelandic basalts by Carbfix. A key indicator of success in the first of these tests was…

Sleipner CO₂ securely stored deep beneath seabed, in spite of unexpected Hugin fracture discovery Open
General readers of Nature may now think that the proposition to store carbon dioxide in deep geological strata is doomed to fail (Monastersky 2013). This is far from the case, as a more balanced review could easily have pointed out. It is …

Geosciences and the Energy Transition Open
A substantial and rapid decarbonisation of the global economy is required to limit anthropogenic climate change to well below 2°C average global heating by 2050. Yet, emissions from fossil fuel energy generation—which dominate global green…

Constraining the Geochemical Fingerprints of Gases from the UK Carboniferous Coal Measures at the Glasgow Geoenergy Observatories Field Site, Scotland Open
Usage of thermal energy contained in abandoned, flooded, coal mines has the potential to contribute to low carbon heating or cooling supply and assist in meeting net-zero carbon emission targets. However, hazardous ground gases, such as CH…

Multi-Isotope Geochemical Baseline Study of the Carbon Management Canada Research Institutes CCS Field Research Station (Alberta, Canada), Prior to CO <sub>2</sub> Injection Open
Carbon capture and storage (CCS) is an industrial scale mitigation strategy for reducing anthropogenic CO 2 from entering the atmosphere. However, for CCS to be routinely deployed, it is critical that the security of the stored CO 2 can be…
