ICaRE4Farms (I4F) intends to boost the use of solar thermal energy (STE) in farming in NWE, to contribute to reduce GHG emissions and increase the share of renewable energies, to help the transition to a low-carbon economy and meet the EU 2030 goal of 27% share for RE. STE is an affordable RE to heat water and has a huge potential to replace fossil energies. However, in the NWE region it only provides 1.1% of total energy consumption and 0.25% of that in agriculture, due to low efficiency of current systems in areas with low solar irradiance. Through transnational cooperation, I4F will test next generation STE systems in 4 agricultural sectors that require hot water to feed livestock (calves) and heat farm buildings (poultry, pigs) and greenhouses (horticulture). The technology that I4F will test is up to 3 times more efficient than traditional STE systems (900 vs. 350kWh/m²). It has shown to be reliable, affordable, easy to install and long lifetime (40 years) with low maintenance requirements. It allows a 70% reduction of GHG emitted for water heating. The partners will share good practices and implement the solution taking into account the features of each region and sector, will install and monitor 4 pilot sites to test and demonstrate the technology, and will support the deployment of other 17 flagship STE systems to improve the economic model and validate the GHG cuts. The outcome of the monitoring will be fed into a feasibility assessment tool and digital model of the STE system, including a software for the farmers to manage the system. The project partners will build a transnational network of distributors and installers to roll-out STE in NWE, to lead the market uptake. In 10 years, it is expected that nearly 1,000 STE systems will be operational in NWE (10 new sites per year in the first 5 years and 20 in the next 5), saving 92 ktCO2 per year, equivalent to 1,4% of CO2 emissions in agriculture in NWE in 2016 and generate 200 new jobs.
