Abstract

Listen

Sustainability of current energy policies and their mid-term outlooks are investigated. First, an overview is given about the trend of global energy demand and energy production. The share of energy sources and the geographic distribution of demand are analysed on the basis of the statistics and projections published by major agencies. Sustainability of selected renewable energy sources is then explored. Finally, potential use of Hydrogen for energy storage in systems with high share of renewable sources is investigated.

Biomasses appear to be among the most interesting energy sources, as they provide a close approximation to a closed life-cycle: energy is produced while releasing as a waste product CO2 that in turn can be fixed in new vegetal species by photosynthesis and solar radiation

Summary

Introduction

The concept of sustainability involves a web of environmental, economic and social factors and in the field of energy it clearly shows its complex interdisciplinary nature. Fossil fuels currently are the most common energy source, and only infrequently are associated to CCS installations This is causing release of Carbon Dioxide (CO2) at a rate higher than absorption by forests, oceans and other natural CO2 sinks, resulting, as it is widely accepted, in the already perceived global temperature increase. In emerging countries a reduced use of coal and hydrocarbons would be an unacceptable burden, as low-cost energy is essential for their industrial growth, which in turn is a prerequisite to increase population welfare. Further relevant savings could arise from the reduction of losses along electricity distribution grids: they are nearly 2% in Europe, but are larger than 5% in many countries, and, despite recent improvements, are still close to 20% in India
