Summary
Tabreed, in partnership with Ireland-based HT Materials Science (HTMS), has concluded what is believed to be the world’s first pilot project of its kind, demonstrating results that provide real hope for significant gains in energy efficiency.
Applied across Tabreed’s current portfolio of 89 district cooling plants, the heat transfer fluid technology developed by HTMS – known as ‘Maxwell’ – could result in efficiency increases of between nine- and 15%. Theoretically, this could mean preventing approximately 200,000 metric tons of greenhouse gas (GHG) emissions annually, as a result of decreased electrical energy consumption. For context, this would equate to removing 43,500 cars from the roads each year as a result of saving 335 million kWh of electricity, which is enough to power approximately 20,000 homes.
Maxwell, named after James Clerk Maxwell, the pioneering scientist who first developed the concept of nanofluids in the 19th century, is an engineered suspension of sub-micron aluminium oxide particles in a base fluid of water or water/glycol (nanofluid) – a drop-in additive for cooling and heating systems, that works by enhancing heat transfer. It was trialled in the summer of 2023 at a Tabreed district cooling plant in Khalifah City, Abu Dhabi, which exclusively supplies chilled water to a 55,742 square metre educational campus.
