Dutch crowdfunded biogas plant supplies first biomethane-to-grid
In the Netherlands, bioenergy technology specialists HoSt has announced that after a successful 24-hours test last week, the biogas plant in Alphen-Chaam has now supplied its first biomethane to the regional gas grid.
Construction of the biogas-to-biomethane plant began in August 2018 and, of particular noteworthiness, the ‘Van Eijck Groengas’ biogas project was the very first biogas project on the crowdfunding platform Oneplanetcrowd. Within one week, the target amount of EUR 900 000 was crowdfunded and a total of EUR 1.1 million for the project was raised.
Using anaerobic digestion (AD) technology the biogas plant processes 43 650 tonnes of manure and a maximum of 5 percent agricultural co-products per year to produce 2.4 million Nm3 biomethane, which is fed into the regional gas grid. The digestate is separated: the thin faction will be supplied to arable farmers.
To cover the heat consumption, maximum heat recovery is applied by the use of a heat pump, which results in high overall plant efficiency. All the products are stored in enclosed spaces and the exiting air is first treated with an advanced air treatment technique to ensure minimal odour.
In addition to the turn-key supply and construction of the biogas plant and upgrading technology, HoSt will also provide maintenance for the biogas upgrading system based on a 24/7 service contract. The plant receives the Dutch government’s “Stimulation of Sustainable Energy Production” subsidiary SDE+.
