About

Founded in 2018, Hydrobag Special Products BV is a private headquartered in Emmer-Compascuum, Netherlands with approximately 50-200 employees specializing in Solar, Hydrogen, Energy Storage.

Hydrobag Special Products BV is a Dutch renewable energy company specializing in thermal energy storage solutions. Founded in 2018 and officially launched on the market in 2020, the company manufactures innovative flexible thermal buffer tanks (Hydrobag) made from durable EPDM material. These tanks store excess heat from renewable sources including solar collectors (heatpipes), heat pumps, solar panels, and biomass boilers for later use, reducing reliance on gas heating and optimizing energy consumption. The Hydrobag system can achieve 50% energy cost savings with heatpipes and CV ketels, or near 100% gas-free operation when combined with heat pumps. Available in standard sizes from 500 to 10,000 liters, the flexible tanks fit in crawl spaces, attics, or outdoor locations. With a 40-year lifespan, minimal heat loss (0.4-0.5°C per 12 hours), and annual maintenance requirements, the system typically achieves payback periods of 5-7 years. Hydrobag manufactures products in-house in Emmer-Compascuum and has installed hundreds of systems across the BeNeLux region, supporting both residential and commercial applications including offices, retail spaces, and industrial facilities.
