Total integration of renewable and fossil energy aiming to a clean and sustainable energy system

Abstract

This paper presents a new concept of total integration of renewable and fossil energies (TIRFE), represented by an octagonal structure of all sources, vectors of transmission and optimization of consumption, aiming a clean and sustainable energy system. The main TIRFE technologies are: cogeneration of H2 and electric energy (EE) by biomass gasification in supercritical water integrated with a thermoelectric unit (H2-BGSCW/TEU); use of H2 from biomass in oil refinery processes for production of light and clean derivatives; supply of H2 deficiency for methanol production from coal; carbon sequestration by a basket of technologies (exhausted P&G wells, underground saline aquifers, forests and stockpile of cellulignin-CL-produced from forest residues); use of H2-BGSCW/TEU as district CHP with photovoltaic panels for EE, including electric car battery recharge; optimization of energy consumption by verticalization of the cities replacing low strength materials (bricks and common cement) by high performance concrete with addition of silica from rice husk. TIRFE helps to solve key problems of H2-BGSCW/TEU, such as materials, energy recovery, plugging, corrosion, economics and energy security for the first generation of plants, and organizes the development for the second generation. TIRFE can be incrementally implanted in existent and new cities.
