Sensitivity of CO2 Emissions to Renewable Energy Penetration for Regions Utilizing Power and Water Cogeneration

RE-mapping the UAE’s energy transition: An economy-wide assessment of renewable energy options and their policy implications

“…The displacement of one kW h of conventionallygenerated power results in a reduction of $ 0.02 m 3 of desalinated water production, assuming a constant, optimal PWR of 15:1 [10]. The 'water-gap' is equivalent to 0.91MCMD (200MIGD) or 12% of the 2012 installed capacity and could be serviced using renewables either by RO plants utilizing RE electricity or by new MED plants that use low-grade heat from solar or geothermal.…”

“…Water cogeneration impacts power plant efficiency for electricity generation. This is especially true in the winter due to the reduced demand for electricity while water demand stays the samedropping the power-to-water ratio (PWR) to lower than optimal efficiency for the power plant operation [10].…”
