Croatia is preparing its first subsidy program for heat pumps with seawater for heating and cooling. Professor Neven Duić says the technology could be used throughout the Adriatic coast and for buildings near rivers and lakes.
The Ministry of Regional Development and EU Funds will issue a public call by the end of the month for using sea temperature to provide heating and cooling, Jutarnji.hr reported. It is the first scheme in Croatia designed specifically for the purpose since it started drawing European Union funds, according to the article.
The draft refers to converting energy from the sea in general, but the only eligible technology this time will be heat pumps for buildings on the coast, the media outlet revealed and added the budget is EUR 1.5 million.
Professor at the Faculty of Mechanical Engineering and Naval Architecture at the University of Zagreb Neven Duić praised the plan and stressed all the hotels on the Adriatic shore and cities with district heating systems could benefit from such subsidies.
“There is a possibility to install heat pumps in a big part of the coast. Areas near big rivers like the Sava and Danube are also suitable, but the technology can also be implemented next to lakes. Actually, Stockholm has been using municipal wastewater for heating for many years. Groundwater can also be utilized. Palace Hotel Zagreb installed such a system,” he told Balkan Green Energy News.
Using wave or tidal energy as well as seawater heat exchangers is still in the early stages in the European Union, but they are included in the solutions supported through a massive financial package within the European Green Deal. Croatia has a long sea coast, which makes the heating and cooling technology especially beneficial, the ministry said, as quoted by the news website.
