SolDAC is moving forward! In December 2024, a crucial step in the SolDAC project took place as experts from CNR and the University of Lleida gathered at the University of Lleida’s premises. Their mission? To advance the integration of two cutting-edge technologies: the water harvester unit and the full spectrum solar system. This milestone paves the way for more efficient direct air capture (DAC) and deep dehumidification processes.
What makes the full spectrum solar system revolutionary?
Unlike conventional solar panels, the full spectrum solar system doesn’t just generate electricity. It captures and utilizes electricity, heat, and photons—maximizing energy use from sunlight. In the SolDAC framework, this innovation plays a critical role: the harvested heat is used to dehydrate the sorbent material in the water harvester unit, driving the air’s humidity below 7 g_water/kg_air. This is the first essential step for DAC technology, creating air conditions that allow efficient CO₂ capture.
Beyond carbon capture: industrial applications
The potential of this technology goes far beyond DAC. By enabling deep dehumidification, it opens new opportunities in industrial sectors where ultra-dry air is required. A prime example is Li-ion battery production, where strict humidity control is vital to ensure safety and product quality. The ability to efficiently remove moisture from the air could lead to breakthroughs in manufacturing processes that depend on controlled environmental conditions.
Collaboration driving innovation
The synergy between CNR and the University of Lleida is accelerating the development of sustainable climate technologies. The December meeting marked an important phase in the real-world implementation of integrated renewable energy and carbon capture solutions—an achievement that aligns with the EU’s ambitious climate goals.
What’s next?
The SolDAC team will now focus on optimizing the integration process and testing the system’s efficiency under different conditions. As we push the boundaries of solar-driven dehumidification and DAC, we are one step closer to a cleaner, more sustainable future.
Stay tuned for more updates!
