All-Weather Snow machine driven by Renewable Energy Sources

Periodic Reporting for period 2 - SnowRESolution (All-Weather Snow machine driven by Renewable Energy Sources)

Reporting period: 2018-02-01 to 2019-01-31

The economy of the ski and mountain industry is dependent on the randomness and unreliability of snowfall. Ski resorts must counteract the lack of natural snow to guarantee that they can open during the busiest tourist seasons. Snow making machines currently available in the market are both costly economically and for the environment. We resolve these issues by offering a clean-tech snowmaking machine, producing snow of the highest quality. Furthermore, our machine can operate in temperatures above 0°C and therefore it produces snow even when traditional snowmakers (fans and cannons) cannot. The proprietary technology is based on a steam jet ejector chiller (SJEC) and uses the triple point of water. The thermal energy for the ejector can be provided by solar collectors or by a biomass steam boiler. Water is the only working fluid in the entire refrigeration system as there are no chemical additives, which guarantees an ecologically friendly concept for the snow supply. Thermal energy for the machine is provided by renewable energy sources, which may be either a solar thermal collector or a biomass steam boiler.
With the Phase 2 project, we have successfully scaled-up the production capacity of the snow machine to 2 m3/h, and started development of a mechanical compressor for reduced energy consumption. We installed the assembly line at our facilities in Rovereto and produced one 1.5 m3/h machine and four 2 m3/h machines. The various machines were installed in pilot sites across Europe including Italy, France and Spain, and even as far afield as New Zealand. The pilot sites covered all weather conditions demonstrating the snow production capacity and the operation with renewable energy sources. We also showcased the Snow4Ever machine at the InterAlpin ski industry fair and the Mountain Planet tradeshow where we raised interest from potential customers and industry stakeholders.
Climate change has caused an increase in average temperature and a decrease of the frequency of snowfalls, is also expected to increase the occurrence of drought and warm periods when traditional snowmaking is not achievable. Producing snow at temperatures above 0°C will extend the time during which snowmaking can be performed and therefore offers the chance to extend the opening season of ski resorts. This will protect the revenues of ski resort and stakeholders in the ski business, and the jobs of hundreds thousands of people employed in the industry. SnowRESolution is the only snowmaker that can be powered by renewable energy sources, which decreases the operating costs for the ski resorts and reduces the environmental impact of snow making (less energy consumption and less carbon emission).
