Water-Energy Nexus // Coal-Based Power Generation and Conversion - Saving Water

This report was commissioned by the Asia-Pacific Economic Cooperation (APEC) to compile and analyse information on technology developments, best practices and current policy measures related to water use for coal-power generation and clean coal technologies in APEC economies. Information was collected from publicly available policy documents, research papers, technical reports, trade publications and supplemented by DNV GL’s internal knowledgebase. The information from documents in the public domain was supplemented by contacting major utilities such as Enel and Eskom to get additional information on their publications.

More than half of the APEC economies generate a significant (>33%) portion of their electricity from coal. However, the focus on clean development necessitates reduction in water consumption for power generation, especially where water resources are stressed. The volume of water required for power generation depends on several factors, such as the generation technology, type of cooling deployed, and site operating conditions. The water used for these plants in turn consumes considerable amounts of energy as this water needs to undergo various physical and chemical treatment processes. The report reviews technologies to reduce water consumption for coal power generation.
