Hydrogen as an energy vector

Abstract

Two of the main problems we are facing at the onset of this new century are the early warning signs of a global environmental crisis, and an increased awareness of the finite nature of our fossil fuel sources and their uneven distribution. These challenges favor a transition to a new energy system based on hydrogen, a clean energy vector. In this paper, the challenges to the introduction of hydrogen on the energy market are discussed, as well as the solutions proposed to overcome them.
