Energy Transition Future with Hydrogen as a Sustainable Energy Source

Abstract

Renewable Energy Sources (RES) and efficiency improvements are the key factor for future energy transition. The huge amounts of fossil fuel that are burned daily through human activities and demand by the growing world population, change dramatically our environmental situation on earth in the coming decades. RES like Wind, Solar, PV, Hydro and efficiency improvement in our energy infrastructure can solve our future energy dilemma on earth. Hydrogen (H2) as a green sustainable secondary energy carrier can help moving in the energy transition future. The objectives of the article demonstrate with two technical applications the possible impact and important issues using Hydrogen (H2) as a green secondary energy source. Energy conversion processes, sustainability, production processes and key applications for H2 fuel, are the scientific aspects. Methodologically a primary energy model is used to show the efficiency chain from Well to Wheel or Room and possible consequences for environmental, economic and technical issues. Practical Hydrogen applications will be analyzed and compared with today´s technology. Out of this analysis general issues can be derived for a possible energy transition future using H2. The result of the analysis shows the critical factors for the transition process working with H2 as a renewable and sustainable energy carrier
