The dataset contains details of field collection of soil gas samples with use of Supel Inert Foil gas sampling bags and the results of methane, ethane, carbon dioxide measurements performed within the environmental monitoring campaign in vicinity of abandoned boreholes on 2 Polish shale gas exploration sites where operations including hydraulic fracturing were conducted in 2010-2016 period.

UKCCSRC Call 2 Project C2-189. The data, which was produced as a result of a UK CCSRC Call 2 funded project, consists of the GC-MS characterisation results for the products collected from the rejuvenation tests of degraded amine sorbents from carbon capture and related model degradation compounds. The examined amine-based sorbent samples included one heavily degraded industrial MEA solvent, one degraded solid-supported polyethyleneimine sample and 6 model MEA degradation compounds (N-(2-Hydroxyethyl)-ethylenediamine, glycylglycine, 2-Oxazolidinone, 1-(2-Hydroxyethyl)-2-imidazolidinone, 1-(2-Hydroxyethyl)-imidazole, N-Acetylethanolamine. Novel reductive approaches, which were investigated as a potential means for rejuvenating the degraded amine sorbents and where the samples for characterisation were produced, included catalytic hydrogenation, hydrous pyrolysis and hydropyrolysis with platinum, nickel and molybdenum as the catalysts used. The dataset also contains some preliminary CO2 absorption test results for a degraded MEA solvent before and after rejuvenation with hydrous pyrolysis using a continuous reactor. Full technical details of the research are contained in the final report submitted to UK CCSRC.

The dataset contains details of field collection of groundwater samples with use of different water intake devices and the measurement results of gaseous compounds (methane) obtained during analytical method validation performed in order to develop a methodology of groundwater sampling for analysis of dissolved gases. The dataset is not intended to be used for any site characterisation. Sampling sites were chosen based on high probability of occurrence of measureable methane content in groundwater. Furthermore, the data will be used for formal procedure to obtain the methodology accreditation from the Polish Centre for Accreditation (PCA). The dataset was created within SECURe project (Subsurface Evaluation of CCS and Unconventional Risks) - https://www.securegeoenergy.eu/. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 764531
