Water use intensity is projected to increase for many of the leading decarbonization pathways for fossil power generation. These include fuel switching (e.g. biomass, hydrogen) and carbon capture and storage (CCS). In many parts of the US, water scarcity is already a key consideration both for management of current systems as well as for planning of future investments. This motivates additional effort at reducing power plant water intensity through operation improvements, technology selection, and sourcing of non-traditional waters.
