What is STEM’s Innovation?
A GREEN TECH THAT REVOLUTIONIZES THE RACE FOR ENERGY SAVINGS – that’s the bold promise behind this breakthrough. Emerging as a spin‐off from the École des Mines Paris-PSL in 2020, STEM has introduced an inventive approach for air and water treatment that taps into the potential of residual heat sources. Instead of relying on conventional electricity, this technology harnesses waste heat – free energy that transforms how industries view efficiency. By capturing the simplicity of water vapor exchange through a membrane, this method not only saves energy but also redefines the possibilities of heat recovery. The approach is built on the physics of phase change and leverages an ingenious twist: condensing and evaporating water in a controlled design. Tested rigorously, the process delivers reliable performance while inviting industries to transition from high-cost, high-emission systems to smart, sustainable alternatives… a refreshing take on an age-old challenge.
Main Benefit
STEM’s solution brings tangible benefits that disrupt traditional practices. The technology offers impressive energy savings and environmental advantages, supported by compelling figures that confirm its efficiency:
- Up to 75% energy savings
- 3 Patents secured – the first filed in 2018 and granted at the end of 2022, the second filed in March 2023, and the third filed in September 2024
- 2 pilot sites already in operation, validating its real-world success
These numbers speak volumes about the leap forward in technology and performance. Integrators are taking notice, as these breakthroughs offer a clear path to both innovative design and measurable sustainability gains.
Technological Challenge and Traditional Methods
For 25 long years, technological solutions for air and water treatment remained stagnant, lacking the dynamism needed to tackle modern energy and climate demands. Traditional approaches relied heavily on outdated energy consumption methods, offering only marginal improvements despite repeated efforts. The persistence of these conventional techniques left a significant gap—a gap that STEM now fills. With no substantial advancements in decades, the old systems failed to provide the efficiency or environmental benefits required by today’s industries. This long-standing challenge created the perfect backdrop for a revolutionary idea, one that questions the limits of traditional methods and dares to reimagine them entirely… proving that a fresh perspective can break through entrenched inefficiencies.
Innovative Process in Focus
At the heart of this green tech lies a simple principle: water vapor exchange through a membrane. This process relies on a patented heat exchange method involving the condensation and evaporation of water, making it both elegant and effective. Products such as NEODRY for air dehumidification, AQUAHIVE for water distillation, and NEOPOOL—which ingeniously combines the strengths of both approaches—underscore the versatility of this design. The membrane system operates with precision, using residual heat that would otherwise be wasted. This simplicity is deceptive; its effectiveness has been validated through rigorous testing in pilot projects and real-world applications. By focusing on the fundamentals of heat and mass transfer, the technology turns a once-overlooked energy source into a powerful asset for air and water treatment.
Real-World Impact and Applications
Beyond theoretical models and laboratory experiments, STEM’s innovations have proven their mettle in real-world applications. Pilot sites around the country have demonstrated that this technology works reliably under operational conditions, addressing the severe environmental impact of industrial and tertiary processes. Actual performance metrics show energy savings ranging from 30% up to 90%, while reducing CO2 emissions significantly. Industries now have access to solutions that tackle air dehumidification, water distillation, and even simultaneous air treatment with water heating – all enabled by this forward-thinking design. With a combination of waste heat recovery and smart AI-powered optimization, the technology is not only cutting costs but also paving the way for cleaner production practices. This real-life validation confirms that a practical, high-impact solution is now available where outdated systems once dominated.
