Germany: Vacuum Super Insulation Reduces Heat Losses at Long-term Storage

Submitted by Baerbel Epp on February 4, 2013

The vacuum super insulation (VSI) by German manufacturer Hummelsberger ensures minimum heat losses when storing solar heat over long periods. This is especially interesting to solar space heating and domestic hot water with a high solar fraction, but also to industrial process heat at higher temperatures. At the SMEThermal 2013 conference in Berlin, Jürgen Melzer, CEO of Hummelsberger, and Manfred Reuß, Group Manager Solar Thermal at the Bavarian Center for Applied Energy Research, ZAE Bayern, explained the design, working principle and possibilities of vacuum-insulated solar storage tanks (see the attached document).
