HoSt Supplies Renewable Heat to Greenhouse Companies  

For the next 13 years, six greenhouse horticulture companies in the area ‘Het Grootslag’ located in Andijk, province North-Holland of the Netherlands will collectively purchase renewable heat directly from HoSt. For this purpose HoSt is realizing the new 15 MWth biomass-fired heat and power plant that the company will operate commercially.  The first heat supply is planned in the first quarter of 2020.

The biomass-fired heat and power installation is equipped with a 15 MWth fire-tube boiler. A bag house filter takes care of filtering and collecting dust. Flue gas cleaning technology, in the form of urea injection into the furnace, provides the installation with guaranteed low dust and nitrogen dioxide emissions (dust: 3and NOx <145/Nm3). Very high fuel efficiency is achieved through the use of a flue gas condenser that supplies up to 30 percent extra heat.

Greenhouse horticulture area ‘Het Grootslag’ covers approximately 370 hectares. Around 200 hectares of greenhouses in the area are connected to a local heat distribution network, which will be co-heated with renewable biomass heat from HoSt from 2020. The Dutch greenhouse horticulture sectors must meet stringent reduction targets for reducing natural gas consumption and CO2 emissions, which is why multiple greenhouse companies in the area invest in various forms of new energy. Recently, Energy Combination Wieringermeer (ECW), a network organization dedicated to the energy infrastructure of the area, opened the new geothermal power plant. Here, geothermal energy is extracted as alternative to natural gas.

The project is funded by ASN Bank as well as by the Dutch National Fund for Green Investments (Nationaal Groenfonds). In addition, the project receives SDE+ subsidy (Stimulation of Sustainable Energy Production) from the Netherlands Enterprise Agency (RVO).
