Several current trends are increasing the urgency to address the energy-water nexus in an integrated way, both in the U.S. and China. Precipitation and temperature patterns are undergoing rapid change with increasing frequency and intensity of extreme events. Population growth and regional migration trends indicate that the population in certain arid areas (such as the Southwest United States) is likely to continue to increase, further impacting the management of both energy and water systems. The introduction of new technologies in the energy and water domains could shift water and energy demands. Moreover, policy developments addressing water impacts of energy production are introducing additional complexities for decision making. As both the challenges and opportunities at the energy-water nexus within the U.S. are mirrored in China, productive research collaboration is expected to benefit both nations.
The CERC Water and Energy Technologies Consortium (CERC WET) aims to build and share knowledge, technologies, human capabilities, and relationships that position China and the United States, in particular with relevant industries and non-profits, to thrive in a future with constrained energy and water resources in a changing global climate. Dr. Ashok Gadgil from University of California, Berkeley leads the U.S. consortium, and Liu He, from Research Institute of Petroleum Exploration & Development (RIPED) leads the Chinese consortium.
The U.S. and Chinese consortia (collectively, CERC WET) have agreed to a Joint Work Plan (Bilingual PDF) to significantly advance water and energy technologies, in both China and the United States. U.S. and Chinese officials simultaneously agreed to a Technology Management Plan (TMP) (Bilingual PDF) regarding intellectual property rights. The Agreement (English PDF Chinese PDF) protects American and Chinese research, scientists, and engineers by ensuring their intellectual property rights for the technology they create.
The overarching objective is to address electricity needs, particularly in regions where water is scarce, by creating technological breakthroughs in the areas of water recovery system, dry cooling, non-conventional power conversion, dry carbon-capture methods, and reduced fuel consumption for thermoelectric power plants. The research projects are aimed at developing new approaches to reduce water consumption and emissions from thermoelectric plants.
Researchers are leveraging existing expertise to create new, integrated solutions that will enable the expanded use of non-traditional waters with an emphasis on desalination techniques, natural treatment systems to remove contaminants, and forward osmosis technologies. Researchers are developing models that provide comparative scenarios for non-traditional water management, gain a broader understanding of regional factors, and support technology selection.
Research focus is to improve sustainable hydropower design and operation and to evaluate system reliability under non-stationary hydroclimates. Researchers are developing short-term optimal operational strategies for hydropower facilities; improving life-time design and operations of hydropower facilities under nonstationary hydroclimates; developing remote-sensing precipitation monitoring and forecasts platform to support short-term hydropower scheduling and examining system resilience under extreme events; and assessing hydropower dispatch on electric grids and its social impacts.
The focus is to project future changes in the hydrological cycle of the American West and China, to evaluate these projections against the historical record, and use the validated projections to quantify the impacts of the changing hydrological cycle on power plants, electric grid operations, hydropower generation, and power requirements for the reliable provision of water supplies. The primary goal is to improve our understanding of the resiliency and risks associated with critical energy and water resources.
Researchers will provide insights for future energy-water nexus management decisions in the United States and China. The research team is identifying technology and energy development pathways to maximize water and energy efficiency, conduct policy analysis, and provide recommendations for optimal co- control of energy and water.
