Open AccessIncorporation of Rare Earths and Yttrium in Calcite: A Critical Re-evaluation
The reported partition coefficients of REE with calcite are reviewed and critically discussed. In some of the reported experimental sets, REE concentrations are found to be supersaturated with respect to indiv...

The H2STORE Project: Hydrogen Underground Storage – A Feasible Way in Storing Electrical Power in Geological Media?
The large scale storage of energy is a great challenge arising from the planned transition from nuclear and CO2-emitting power generation to renewable energy production, by e.g. wind, solar, and biomass in German...

Modelling CO2-induced fluid–rock interactions in the Altensalzwedel gas reservoir. Part I: from experimental data to a reference geochemical model
Modelling fluid–rock interactions induced by CO2 is a key issue when evaluating the technical feasibility and long-term safety assessment of CO2 storage projects in deep formations. The German R&D programme CLEAN...

Modelling CO2-induced fluid–rock interactions in the Altensalzwedel gas reservoir. Part II: coupled reactive transport simulation
Injection of CO2 into gas reservoirs for CO2-enhanced gas recovery will initiate a series of geochemical reactions between pore fluids and solid phases. To simulate these conditions, the coupled multiphase flow a...
