Store heat smarter. Deliver it when it matters. That’s Muspell. ⚡ PCM + TCM = flexible heat delivery 🔥 Innovative heat exchangers = more power 🧪 New materials = higher energy density, lower critical-material dependency ♻️ Solid-solid PCMs = no leakage, minimal volume change

#Muspell is developing a compact, flexible and modular mid-to-long-term #TESS with increased energy density & integrated heat-pump capabilities. Better energy management, greater flexibility, cost savings and renewable energy integration. Energy shouldn’t come with an expiry date
