Pit Thermal Energy Storage Solutions
Future-proof heating for a net zero world
Decarbonizing the heating sector requires more than renewable energy generation — it requires smart, large scale energy storage. Pit Thermal Energy Storage (PTES) is a proven solution that bridges the gap between heat production and demand. It enables sustainable, cost-efficient heating for communities, industries and district heating networks, supporting the global transition to Net Zero.
At Solmax, we’ve united our expertise in advanced materials, engineering, and installation services under one name: ENERVIA™ – derived from Latin and meaning “the way of energy,” reflecting a holistic approach to Pit Thermal Energy Storage (PTES).
ENERVIA is more than a solution; it’s a complete ecosystem for Pit Thermal Energy Storage (PTES). From high-performance geosynthetic materials to specialized consulting and precision installation, our dedicated team delivers end-to-end solutions designed for efficiency, reliability, and sustainability.
Every ENERVIA project is powered by Solmax’s proven technologies and the know-how of experts trained exclusively on our products. The result? Future-ready systems that accelerate the decarbonization of heat and help you meet your energy goals with confidence.
