  1. 21. Design of a Polygeneration system in Filipinas ETCR, Colombia

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Germán Ropero Pérez; [2021]
    Keywords : ;

    Abstract : This project has addressed the design of a cost-effective Polygeneration system that guarantees a continuous, equitable and environmentally friendly energy supply for the rural settlement of Filipinas ETCR, (in Spanish, Espacios Territoriales de Capacitación y Reincorporación) Colombia, which is currently not achieved, due to a system that relies on the national electricity grid (with numerous outages) and on LPG (Liquefied Petroleum Gas) and wood to meet the thermal demand, mainly for cooking. For this purpose, in addition to the current energy supply situation, the energy demand according to type (electricity and heat) and sector (residential, commercial and agro-livestock) is characterized.

    Abstract : Flygindustrin närmar sig ett vägval där sektorn kommer behöva bestämma sig för vilken typ av framtida energimöjligheter den ska använda sig av. En väg är att även fortsättningsvis använda sig konventionellt flygbränsle vilket med stor sannolikhet kommer leda till fortsatt ökande utsläpp globalt, och den andra vägen leder sektorn till hållbart flygbränsle, vätgasdrift och batteridrivna elektriska flygplan.
