Abstract
Quality measure for of energy is exergy. Amount of exergy in energy carriers is very different and prices includs value of quantity and not of the energy quality. Exergy is measure for quality of energy, because the only part of energy available to do work is exergy. Transition to sustainable energy system, without GHG emissions, based on RE, open the questions how to evaluate exergy from solar energy. Solar energy in all form (irradiation, water flows, wind, and biomass) consists from nearly 100% of exergy. Solar energy is for free, conversion systems are not. To exploit at maximum the present infrastructure there is common agreement that we need sustainable energy system with four main energy carriers: electricity, gaseous, liquid and solid fuels. Our vision is the new Sustainable Energy System (SES) based on the biomass carbon recycling using solar and planetary energy for electricity and hydrogen production. SES is based on the existing infrastructure and known chemical processes. With regards to availability of renewable energy resources (RES) it is unrestricted in comparison to present fossil fuels use. The proposed SES consists of the three main energy carriers: electricity, synthetic methane (CH4) and synthetic methanol (CH3OH). Tha last two present also the chemical storage of solar energy.
