Assessing the Potential of Underground Hydrogen Storage in Poland

A group of researchers – Reza Derakhshani, Leszek Lankof, Amin GhasemiNejad & Mojtaba Zaresefat – have finished an interesting study relating to underground hydrogen storage in Poland. 

The abstract

“This study explores the feasibility of utilising bedded salt deposits as sites for underground hydrogen storage.

“We introduce an innovative artificial intelligence framework that applies multi-criteria decision-making and spatial data analysis to identify the most suitable locations for storing hydrogen in salt caverns,” as said in report abstract.

The approach integrates a unified platform with eight distinct machine-learning algorithms—KNN, SVM, LightGBM, XGBoost, MLP, CatBoost, GBR, and MLR—creating rock salt deposit suitability maps for hydrogen storage.

The performance of these algorithms was evaluated using various metrics, including Mean Squared Error (MSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), Root Mean Square Error (RMSE), and Correlation Coefficient (R2), compared against an actual dataset. 

The CatBoost model demonstrated exceptional performance, achieving an R2 of 0.88, MSE of 0.0816, MAE of 0.1994, RMSE of 0.2833, and MAPE of 0.0163.

The novel methodology, leveraging advanced machine learning techniques, offers a unique perspective in assessing the potential of underground hydrogen storage in Poland.

This approach is a valuable asset for various stakeholders, including government bodies, geological services, renewable energy facilities, and the chemical/petrochemical industry, aiding them in identifying optimal locations for hydrogen storage.

Research could have a significant on an ongoing scientific discourse

The implications of their work extend to governmental and European Union institutions. They are key players in the infrastructure development for renewable energy storage.

Additionally, the outcomes of this research are poised to contribute significantly to the ongoing discourse within the scientific community regarding hydrogen storage solutions, offering empirical data to inform policy decisions.
