简要介绍: | This century will definitively witness the replacement of current fossil fuels (i.e., oil, natural gas, and coal) with renewable energy sources. Currently, fossil fuels account for almost 80 % of the total energy consumed worldwide and, consequently, there is still a long way to walk before this replacement comes true. Renewable energy-based technologies are being improved fast and they are, little by little, reducing the development level gap with the well-known and optimized fossil technologies. This book offers a compendium of works describing these efforts on some of the most representative renewable technologies. The first five chapters are dedicated to biomass, the only renewable source of organic carbon available on Earth and thus, the only sustainable source for fuels and chemicals. Hydrogen is considered by many as the energy vector of the future. |
