Guidelines for wastewater treatment technologies in preparation

Operating a wastewater treatment plant is a complex task in itself. If you start thinking about using solar energy to drive certain separation or disinfection processes, the task becomes even more challenging (as the graphic above shows). Water treatment plant operators who want to harness more solar energy would benefit …

Superbonus has pushed solar heat in Italy

The combination of the Conto Termico incentive scheme, supporting renewable heat installations, and the 110 % Superbonus for energy efficiency in buildings allowed Italy to hit a record year for solar thermal in 2021. According to the industry association ANIMA, 225,000 m2 of collector area (158 MW) were installed in …
Cities Going Carbon Neutral

Celsius’s cities are going carbon neutral with waste heat and PV rather than with solar thermal

Waste heat and photovoltaics seem to be the preferred technologies for cities aiming to decarbonize their energy supply, rather than solar heat. This became clear during the webinar Cities Going Carbon Neutral at the end of February. During the presentations by energy experts from the Swedish city of Lund, Sonderborg …
