INTEGRATING RENEWABLE ENERGY IN WATER SYSTEMS: DESIGN CASE STUDIES FOR THE GALáPAGOS ISLANDS

摘要

A new methodology was used to explore a range of water treatment scenarios for the population centers on the four inhabited islands of the Galápagos archipelago. The met meth- hodology combines a odology sustainability sustainability-oriented decision matrix, comparisons of water treatment system energy use, and simulations of grid grid-connected renewable energy systems for the water systems. Treatment technologies were screened with the sustainabi sustainability ity-oriented decision matr matrix. Typical ix. Water treatment system energy consumption for each appr appro- opriate process train was calculated and HOMER software priate was used to determine economically optimal grid grid-connected renewable energy systems providing a 70% renewable fra frac- ction. Water trea tion. Treatmen ment process trains for each island were t compared over the 20 20-year project lifetime using HOMER simulation r results. Preliminary design recommendations and sults. Cost est estimates for both the water treatment and renewable mates energy systems were developed for each locatio location. R n. Results sults indicate the importance of including energy consider considerations tions in the selection of appropriate water treatment systems.
