Welcome to this week’s edition of the “Our Future Water” newsletter, where we explore the crucial intersection of water and energy in driving sustainability. In an increasingly pressing era where resource scarcity and environmental challenges, innovative water and energy solutions offer a path towards resilience and sustainability.
Insights
Low-Energy Desalination Technologies: Revolutionizing Water Supply
Low-energy desalination technologies are revolutionizing water supply by making seawater and brackish water desalination more sustainable and accessible. These innovations use advanced membranes, energy recovery devices, and optimized processes to cut energy consumption and costs. Improving desalination efficiency can provide reliable freshwater to arid regions and coastal cities, reducing reliance on over-exploited sources and enhancing water security. Discover how Singapore is seeking innovators to develop low-energy desalination technologies.
Hydropower and Cogeneration: Harnessing Energy from Water Utilities
Water utilities play a crucial role in energy production through hydropower and cogeneration. Hydropower generates renewable, low-emission electricity from flowing water, while cogeneration (CHP) uses heat from electricity generation for heating buildings and industrial processes. Integrating these technologies helps utilities reduce their carbon footprint, improve energy efficiency, and support sustainable water management, enhancing the resilience of energy systems. Explore how Athens’ water utility is developing hydropower.
Anaerobic Digestion: Converting Waste to Energy
Anaerobic digestion converts organic waste like crop residues and food waste into biogas through microbial activity. Water utilities can use this technology to turn wastewater sludge into renewable energy, powering treatment plants and reducing costs and emissions. The byproduct, digestate, serves as a nutrient-rich fertilizer, promoting sustainable agriculture. This process integrates waste management and energy production, enhancing resource recovery and environmental sustainability. Read how Severn Trent is powered by energy crops and food waste.
