Exploring the Power of the Solar Air Water Generator (SAWG). Developed through a collaboration between AQUOVUM, Azelio, and Khalifa University, the project aims to generate clean, off-grid drinking water from air using solar energy and thermal storage. This marks a critical innovation in the field of water technology with zero carbon emissions.

What Is a Solar-Air-Water Generator?

A solar air water generator (SAWG) extracts humidity from ambient air and condenses it to produce potable water. Unlike standard AWGs that rely on grid electricity, this Masdar project incorporates solar-thermal energy storage, allowing continuous operation even after sunset. The ability to function off-grid makes it ideal for remote and arid regions.

How Does the System Work?

The pilot system integrates cutting-edge technologies :

A 450 kW photovoltaic solar array supplies energy during daylight.

Azelio’s TES.POD® stores heat from the sun in recycled aluminum and converts it to electricity on demand using a Stirling engine.

AQUOVUM’s AWG units use this electricity to power dehumidification and filtration systems, producing clean drinking water. Each unit generates up to 1,000 liters per day, with scalability up to 7,500 liters per day based on demand.

This integration of TES ensures water production 24/7, overcoming a major limitation of solar-only systems. The use of recycled aluminum in storage also reflects the project’s focus on sustainability.

Why This Matters: The Water Crisis and a Net-Zero Future

Zero Emissions and Energy Independence

This solution eliminates reliance on fossil fuels or battery storage, significantly reducing emissions. In contrast to desalination, which is energy-intensive and emits CO₂, this system runs entirely on renewable energy, enabling net-zero water production.

Water Security and Global Relevance

Water scarcity affects more than 2 billion people worldwide. By providing decentralized and sustainable access to clean water, this pilot addresses both UAE’s Water Security Strategy 2036 and UN Sustainable Development Goal 6. The technology could serve as a model for other water-stressed countries.

Benefits of the Masdar City Pilot Project

Environmental Benefits

The project drastically reduces pressure on groundwater and eliminates the need for environmentally damaging desalination. It also avoids brine discharge and minimizes the energy-water nexus footprint.

Economic and Social Potential

The AWG market is projected to grow over 25% CAGR globally and more than 30% in the MENA region, indicating strong economic viability. The system is low-maintenance and requires no complex infrastructure, making it scalable in rural, off-grid, or disaster-affected areas.

Applications Beyond the Pilot

This technology has multiple practical applications :

Rural Villages: Ensures year-round access to clean drinking water

Disaster Response: Mobile AWGs can be rapidly deployed in emergency zones.

Urban Farming: Supports rooftop agriculture and closed-loop water reuse in cities.

Military Operations: Provides independent water supply in remote bases

By bypassing the need for traditional water infrastructure, this system empowers communities with resilience and autonomy.

Voices Behind the Innovation

Abdulla Balalaa, Executive Director at Masdar, emphasized the project’s role in advancing sustainable urban development :

“This pilot strengthens our commitment to innovation in sustainable water solutions.”

Robert Wood, CEO of AQUOVUM, added:

“We are proud to work with nature, not against it, to create future-ready water sources.”

Dr. Nicolas Calvet from Khalifa University, leading the academic research, stated :

“We will gather year-long performance data under Masdar’s climate to optimize and scale this technology globally.”

The Road Ahead

The pilot system will operate throughout the year in Masdar City, which offers extreme weather conditions ideal for testing AWG efficiency. If results prove successful, similar setups could be deployed across the UAE, MENA region, Sub-Saharan Africa, and Asia-Pacific. The modular design allows systems to be tailored to local needs with minimal environmental disruption.

Conclusion

Masdar City’s solar-air-water generator is not just a technological milestone—it is a blueprint for sustainable water generation in the face of climate change and population growth. If adopted at scale, such systems can democratize access to clean water while drastically reducing ecological impact.
