Hydrogen Storage Potential of the Graphitic Carbon Nitride

Abstract

The size of the global market of renewable energy has increased significantly in the last years, thanks to new environmental policies that were adopted to slow down the inevitable rise of global temperatures. In this article the focus in on addressing hydrogen storage, that is acceptable for the environment and for security reasons. Today's methods of storing H 2 that are viable for economic use are liquid hydrogen (LH2) and compressed hydrogen, however, they present some risks that other experimental methods do not have. For example, liquid hydrogen can ignite and burn in the presence of oxygen, and it can also create an explosive mixture with air if it evaporates too quickly. The main topic of the research is the study of the economic possibilities of integration of the Graphitic Carbon Nitride g-C3N4, into existing H 2 storage systems and the study of the prospects of creating a new scalable system using Graphitic Carbon Nitride as the base material for storage possibly at Standard Temperature and Pressure (STP). This study aims to make an analysis of the newly proposed system and to compare its general storage possibilities to already-in-use solutions, as a reference to other hydrides.
