Grolsch to produce biomethane using Host’s technology
Host will offtake the biogas from Grolsch’s wastewater treatment plant and install a biogas upgrading system that will produce over 1 million Nm3 of biomethane annually - equivalent to the gas needs of approximately 700 households.
By the end of the year, more than two-thirds of Grolsch’s heat demand will be met by sustainable heat from waste management company Twence, delivered through a new underground pipeline. With this heat supply, not all of Grolsch’s biogas can be used directly for its heat demand. Therefore, the biogas will be upgraded to biomethane in the newly built biogas upgrader.
“With the arrival of the heat pipeline, it is necessary to give biogas another use, in which it is still optimally utilised,” said Susan Ladrak, sustainability manager at Grolsch, “Biomethane is a sustainable, proven efficient application.
“We are very proud of this step as part of our energy transition, in combination with the projects of our sustainable heat purchase and 100% green electricity choice. All of these initiatives bring us a big step closer to our goal of being a carbon-neutral brewery by 2025.
“In fact, by taking these steps, we are reducing our CO2 emissions within Scope 1 and Scope 2 combined by more than 85%.”
Host’s managing director, Jelle Klein Teeselink, commented: “More than half of the biomethane systems in the Netherlands are built by Host and energy-as-a-service collaborations like this are becoming more common.
“This sustainable gas variant plays a key role in the energy transition and, through our technologies, we are able to provide answers to both the energy and waste issues.
“Biomethane is highly suitable for the existing gas grid and for taking sustainability steps in existing buildings and industry. The government strongly stimulates the production of biomethane and there is a great need for alternatives to fossil fuels.
“Part of the Dutch Government’s plans include mandatory blending targets for gas suppliers to add renewable gas to their supply, but we also see a strong increase in demand internationally on all continents. We are very proud of this collaboration close to home.
“The Netherlands is not a leader in getting energy from renewable sources, however, the country has high ambitions. Every initiative is a step closer.”
It is expected that biomethane can be delivered to the gas grid from the third quarter of this year.
