In the future, we will experience a continuously increasing energy demand mostly due to the continuous growth of the world population. Today we use fossil fuels (coal, oil and gas) in order to cover the society’s basic needs. This involves significant CO2 emissions that contribute to the climate change by contributing to the increase of the global temperature. A great number of countries through international...

The inflow into aquifers of transition metals leached from muck disposed in quarries is a process that requires a detailed analysis in the framework of the environmental impact studies of dump sites. It is important to thoroughly examine the risks of potential contamination of pre-existing groundwater wells and, more in general, to assess the risk of qualitative deterioration of nearby shallow aquifers....

The paper provides an overview of the several scientific and technical issues and challenges to be addressed for underground storage of carbon dioxide, hydrogen and mixtures of hydrogen and natural gas. The experience gained on underground energy systems and materials is complemented by new competences to adequately respond to the new needs raised by transition from fossil fuels to renewables. The experimental...

The aim of this paper is to analyze the factors affecting hydrogen as well as Carbon Capture and Storage Technologies (“CCS”) policies with refer to countries’ upstream capacity of hydrocarbon activities. By using a panel data of 79 countries in 20 years, the interactive model will take into consideration Oil Reserves in relationship with Fossil Fuel Consumption, Blue or Green hydrogen...
