ebm-papst: Cooling technologies for direct air capture and battery storage systems

The energy transition requires increasingly innovative solutions to reduce emissions and stabilize the electricity grid. Among these, direct air capture (DAC) and battery storage systems are emerging as key technologies. Both pose complex thermal management challenges: efficiently moving large volumes of air and maintaining batteries within safe temperature ranges are essential to ensuring sustainability, safety, and reliability. ebm-papst , with its expertise in EC ventilation systems, develops solutions that effectively address these challenges.

Efficient ventilation for direct air capture

DAC technology is based on the principle of extracting CO₂ directly from the atmosphere, but this requires moving enormous quantities of air. Fans are a key element in this process: they must ensure high and constant flows while minimizing energy consumption. ebm-papst systems, thanks to the high efficiency of their EC motors, ensure an optimal balance between flow rate and consumption, making an otherwise extremely energy-intensive process sustainable.

Another aspect concerns reliability in harsh operating conditions. Capture units are exposed outdoors and must operate in environments characterized by low temperatures, humidity, and dust. ebm-papst fans are designed to withstand these stresses, maintaining stable performance over time. The option of integrating intelligent control systems also allows fan speed to be adjusted based on environmental conditions, reducing consumption, vibration, and noise, and extending the operating life of the systems.

Advanced thermal management in battery storage systems

Heat management is also a crucial factor in battery storage systems. During charge and discharge cycles, cells generate heat which, if not dissipated properly, can compromise performance or reduce the overall lifespan of the system. For this reason , ebm-papst develops both air and liquid cooling solutions, adaptable to different system configurations. In the former case, compact fans ensure a constant flow that keeps the batteries at optimal temperatures; in the latter, the coolant transfers the heat to a ventilated exchanger, ensuring more precise control in high-energy density systems.

Cooling isn't just about battery modules: electrical panels and conversion electronics also generate heat that must be managed to maintain operational continuity and safety. In this area, ebm-papst solutions offer energy efficiency, quiet operation, and robustness, with the option of integrating ATEX-certified fans where additional safety measures are required to prevent gas or fume risks.

Cooling as a strategic factor for efficiency and safety

Both direct air capture and battery storage require reliable cooling systems . In the first case, it is essential to maximize the energy efficiency of the process, minimizing consumption due to the large air flows involved. In the second, thermal management is essential to extend battery life and ensure system safety. In both cases, robust fan designs and the ability to operate in extreme conditions are essential requirements.

Thanks to its expertise in EC ventilation, ebm-papst provides solutions that not only stabilize operating conditions, but also directly contribute to the reliability and sustainability of new renewable energy technologies.
