Phasic Energy is a British advanced technology company pioneering AI-optimized systems that turn wasted heat into valuable power and cooling. Founded in 2021, it has quickly attracted attention for tackling a niche but critical challenge: improving energy efficiency by harvesting low-grade waste heat from data centers, factories, and even military bases[1][2]. In an era when Europe seeks greater strategic autonomy and sustainability, Phasic’s innovations promise a dual benefit. They can reduce dependence on imported energy storage technologies while strengthening the energy resilience of key infrastructure. The company remains relatively secretive about its proprietary hardware, yet it has signaled enough progress to win industry accolades and entry into NATO’s innovation accelerator. With backing from high-profile partners and recognition from defense and tech communities, Phasic Energy stands at the intersection of green innovation and strategic security needs. Its story illustrates how a deep-tech startup can align climate-conscious engineering with Europe’s broader push for technological sovereignty and defense readiness – a combination intriguing enough to warrant closer examination.
