Sorption chillers may still be a niche market, but Europe’s manufacturers reported rising demand for solar thermal cooling in Italy, Spain and the Middle East in 2017. Solar thermal numbers are on the rise because of three factors: the potential to reduce power consumption, including peak loads; the option to use natural refrigerants, such as water; and the ability to provide demand-responsive heating and cooling throughout the year.

Solarinvent managed to sell three of its new freescoo (free solar cooling) systems in 2017. They are now being tested in a real-life environment. Two small-scale installations were set up in Catania, Italy, and another one in Morocco. Pietro Finocchiaro, CEO of SolarInvent, said: “We focus on smaller units and have received many requests for solar cooling systems over the past two years. We concentrate our sales activities currently on Italy, Spain and Middle East. However, the most promising markets for solar cooling are outside Europe, besides Middle East these are India, China, Brazil and Mexico.”

Mario Colaiemma, Executive Managing Director at Maya, the European distributor of Japanese Yazaki chillers, reported the commissioning of nine solar thermal cooling installations in 2017, a considerable increase over the two systems which the company had installed in Italy in 2016. Six of the new ones were set up in Italy and three in Spain, the majority on commercial buildings. All were connected to collector fields and combine solar cooling with hot water, space heating or both.

However, Colaiemma said that the current market for solar thermal cooling was “rather complicated and definitely not satisfying. Roof space is limited. You have to decide on either PV or solar thermal and, right now, PV is winning the numbers game.”

In the Middle East, several countries and regions, including Kuwait, Saudi Arabia and the Emirate of Dubai, have announced a gradual removal of subsidies for electricity. This, in turn, will generate demand for renewable cooling solutions, as air conditioning is the number one cost factor on private and commercial electricity bills. “We’ve received an increasing number of requests from potential clients in the Middle East,” Bashir Kanawati, Sales Engineer for this region at German chiller manufacturer Fahrenheit, said. In 2017, his company installed a 10 kW sorption chiller at an energy recovery facility in Dubai and it is planning to erect a second demonstration plant at Qassim University in Saudi Arabia. He said that the chiller would be delivered in June and the system would start operating this year.

In early 2018, two German organisations agreed on a joint membership model to promote solar thermal air conditioning and cooling, a niche market in the country. The cooperation between the Green Chiller Association for Sorption Cooling and the Central Association for Refrigeration, Air Conditioning and Heat Pumps, or ZVKKW for short, is hoped to popularise innovative and sustainable cooling solutions.

A search for ‘solar thermal’ in a recently published 195-page document titled Secure, Clean and Efficient Energy will not return encouraging results (see the document at the bottom). The publication by the Horizon 2020 Work Programme 2018-2020 shows only 6 entries in total. “Solar thermal is definitely not a priority of the new programme,” said Daniel Mugnier, Head of R&D at French engineering services company Tecsol. “And even if the European Solar Thermal Technology & Innovation Platform were to try to promote several hot topics, there’s only one call [LC-SC3-RES-7-2019 on solar process heat] dedicated to the technology.”

Substantial solar resources and a generous incentive scheme called Conto Termico 2.0: Perfect conditions, it seems, for the widespread use of solar district heating. But barriers such as a low gas price and the concentration of district heating in a small part of Italy have so far limited deployment to a few installed systems.

There is more than one way to read 2016’s market statistics published by Solar Heat Europe about 2 months ago. One could emphasise the great achievements made in reducing emissions and creating jobs in the solar heating and cooling sector in Europe (first part). One could likewise point to Denmark as a leader in solar district heating. A third possibility would be to concentrate on the continued decline in most key markets in Europe and the stark difference between renewable heating targets and their fulfilment in many countries (second part).
