Greener veggies and flowers – HoSt launches renewable heat as a service
Netherlands-headed bioenergy technology providers HoSt has announced that it is developing a commercial "renewable heat as service" project for six horticultural companies in the ‘Het Grootslag’ area in Andijk, North-Holland province. HoSt will build, operate and maintain a 15 MWth biomass-fired combined heat and power (CHP) plant that will supply renewable heat to greenhouses operated by the companies.
Located in the province of North Holland, the greenhouse horticulture area of ‘Het Grootslag’ covers approximately 370 hectares (ha). About 200 ha of these greenhouses are connected to a local heat distribution network. It is this heat network that will be co-heated with renewable biomass heat by HoSt from 2020.
The Dutch greenhouse horticulture sectors must meet stringent reduction targets for reducing natural gas consumption and fossil carbon dioxide (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 an alternative to natural gas.
Low emissions, high efficiency, no worries
The biomass-fired heat and power (CHP) plant will be equipped with a 15 MWth fire-tube boiler with urea injection in the furnace to reduce NOx emissions. Bag filters will be used for flue gas dust and particulate removal while a flue gas condenser will recover up to 30 percent additional heat making the plant very fuel efficient.
According to HoSt, with its renewable heat supply service, the greenhouse growers “do not have to worry” about the installation. The maintenance and business operation is being carried out entirely by HoSt. The first heat supply is planned in the first quarter of 2020.
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).
