HoSt supplies renewable heat to greenhouse companies ‘Het Grootslag’ in Andijk

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 HoSt will also operate commercially.

With the renewable heat supply service from HoSt, the greenhouse growers do not have to worry about the installation. The maintenance and business operation is totally carried out by HoSt. The first heat supply from biomass (wood chips) is planned in the first quarter of 2020.

Low emissions, high efficiency

The biomass-fired heat and power installation is equipped with a 15 MWth water-tube boiler. Thanks to the bag house filter, that takes care of filtering and collecting dust, and the extensive flue gas cleaning technology, in the form of urea injection into the furnace, the installation has guaranteed low dust and nitrogen dioxide emissions (dust: <5 mg/Nm³ and NOx <145/Nm³). Very high efficiency is achieved through the use of a flue gas condenser that supplies up to 30% extra heat.

Greenhouse horticulture area ‘Het Grootslag’

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 sector 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.

Green financing

The project is funded by ASN Bank, which is committed to sustainable investment, as well as by the Dutch National Fund for Green Investments (Nationaal Groenfonds) that is involved in projects that contribute to a better quality of the green living environment. In addition, the project receives SDE+ subsidy (Stimulation of Sustainable Energy Production) from the Netherlands Enterprise Agency (RVO).
