Our R&D & Laboratory Competency

We develop technologies that tackle the challenges with underground energy storage systems, geothermal systems and CCS/CCUS combining numerical simulation and experimental methods. Our research activities are performed in collaboration with the Institute of Subsurface Energy Systems of the Clausthal University of Technology in Germany.

Simulating Underground Gas Storage Systems

We developed a multi-phase multi-component flow simulator coupling hydro with microbial effects for the future of underground hydrogen storage.

Gases such as hydrogen, methane and carbon dioxide are typically in supercritical state when stored underground.

The flow behaviour of hydrogen, methane and mixtures will be gas-like while carbon dioxide will behave liquid-like due to its high in-situ density.

Still the gases are almost immiscible with brine so that underground storage becomes a complex multi-phase system.

The numerical simulation of gas storage operations requires considering, on top of reservoir rock characteristics, the mixing behaviour between gases with different compositions, mass transfer between the phases by dissolution and vaporisation and changes in gas composition by microbiological reactions.

We have developed a reservoir simulator

tailored for gas storage operations

considering all these aspects.

Site-specific flow and microbiological properties are measured in our laboratories based on fluid and rock samples and used as input for numerical modelling.

This way we generate calibrated and reliable reservoir models

for planning hydrogen and carbon dioxide underground storage facilities

and underground bio-methanation reactors.

Our R&D Projects

SOFTWARE

H2 SIM

Developed a multi-phase multi-component flow simulator coupling hydro with microbial effects for the design and optimisation of underground hydrogen storage.

SenEx

Modelling and calibrating (history matching) reservoirs selected for conversion to underground storage is essential for mitigating the investment risk.

SenEx is a unique and highly efficient well-level assisted history matching software: it usually takes only 10 to 20 simulation runs to arrive at a full field well-level match – irrespective of number of wells and production history.

InspIOR VISION PRO

Developed machine learning (ML) based advanced image analysis software for processing and analysing recorded data. Includes image processing, segmentation, computation and visualisation.

InspIOR VISION

Developed process control, monitoring and data recording software to run laboratory experiments in an automated mode minimising human interaction.

LABORATORY

HydrogenHolder

Developed customised equipment for laboratory experiments with hydrogen and CO2.

Allows visualising the effect of microbes/bacteria on hydrogen, CO2, natural gas and brine systems.

MPVC 20

Developed test kit for fiber optical sensors. Applicable for liquid and gaseous environments, including CO2, hydrogen, methane and similar.

Rock-on-Chip-Sense

Developing and integrating optical pressure and temperature sensors in micromodels to expand the data stream from micromodel experiments.

The project receives funding from the European Regional Development Fund (ERDF) and the Lower Saxony SER Programme.

fluidSens

Developing and integrating optical sensors in microfluidic systems to determine fluid composition.

This R&D project is performed in collaboration with the Fraunhofer Society (Heinrich Hertz Institute, HHI) and is supported by the Federal Ministry of Economics and Technology [BMWi] based on a resolution of the German Parliament.

InspIOR

Designed and developed a microfluidic flooding system for real time visualisation of flow and transport processes in porous systems (geological formations).

Facilitates programmable and automated experiments under reservoir conditions combined with effluents’ fluid analytical chemistry.
