DEWA’s TESTIAC project reduces 44,000 tonnes of CO2 emissions annually

By Emirates24/7

Dubai Electricity and Water Authority (DEWA)’s Thermal Energy Storage and Turbine Inlet Air Chilling (TESTIAC) project implemented in three Gas Turbines at L-Station in Jebel Ali Power and Desalination Complex has contributed to reducing more than 44,000 tonnes of CO2 emissions annually, which is equivalent to the planting of two million trees.

This project is the first of its kind internationally combining Thermal Energy Storage with Inlet Air Chilling in Frame 9F Gas Turbines. This reduces the consumption of natural gas in the electricity production process, which limits greenhouse gas emissions.

“We support the vision of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, to make Dubai a smart and sustainable city and a global centre for clean energy and green economy. We are committed to achieving a balance between development and the environment to protect the rights of future generations to live in a clean, healthy, and safe environment.

This is in accordance with the UN Sustainable Development Goals (SDGs) 2030 and the Dubai Clean Energy Strategy 2050, and the Dubai Net Zero Carbon Emissions Strategy 2050 to provide 100% of Dubai’s total power capacity from clean energy sources by 2050. DEWA contributed to reducing carbon emissions in Dubai by 21% in 2021, exceeding the target in the Dubai Carbon Abatement Strategy 2021, which aimed to reduce 16% of carbon emissions by 2021. We spare no effort to make Dubai a model for clean and renewable energy, sustainability, green economy, carbon reduction, and finding sustainable solutions to mitigate the adverse effects of climate change,” said HE Saeed Mohammed Al Tayer, MD & CEO of DEWA.

The TESTIAC project was implemented to increase the electricity generation capacity of gas turbines during high ambient temperatures in summer by using chilled water to cool the inlet air to gas turbines. The process consumes less energy than the additional energy produced, as it resulted in increasing the cumulative electricity generation capacity of three gas turbines by 111 MW.

The project was awarded the Certified Emissions Reductions (CERs) credit from the United Nations Framework Convention on Climate Change. Dubai Carbon Centre of Excellence (Dubai Carbon) presented the accreditation after the project significantly-exceeded its initial target.
