Pilot project successful – surplus biogas supplies construction sites.

First measurements: significantly less nitrogen on construction site.

Sustainable fuel chain shows proven environmental benefits.

The first measurements by the Hogeschool van Arnhem en Nijmegen (HAN) show that there is much less nitrogen emissions at the construction site of the pilot ‘De Duurzame Brandstofketen (The Sustainable Fuel Chain)’. In this pilot, excess biogas is used as clean fuel for local construction sites.

How does a local sustainable fuel chain work?

The sewage water from the municipalities of Rhenen, Renkum and Wageningen is treated at the Renkum sewage treatment plant of the Vallei en Veluwe water board. Sewage sludge is formed during the purification process. This sludge is fermented and biogas is created from this. This biogas is used to produce electricity and heat for, for example, the processes at the sewage treatment plant. Only the current biogas production is more than the purification itself needs. Gashouders came up with the idea of collecting the excess biogas and converting it into a zero impact fuel. This idea was further developed and realized in collaboration with six partners.

The excess biogas is no longer flared, but collected in filling station of Gashouders. The biogas is converted into a zero-impact fuel and supplied to regional projects of contractor GMB. Buse Gas B.V. is responsible for the development of containers for biogas storage and Koninklijke van Twist is supplying the engine for a hybrid generator, powered by locally produced biogas. HAN is conducting research into the positive environmental impact of the chain.

Measuring is knowing!

The pilot will run until November 1, 2022 and is already showing that it is a promising option for making energy-intensive applications more sustainable and for low-emission charging of electrical equipment. The measured nitrogen emissions turned out to be only a few percent of the permitted legal amount and the emissions of particulate matter were nil. In addition, the measurements offer potential for even more improvement. Koninklijke van Twist wants to optimize the motor control even further. In the coming year, HAN will continue to research the environmental impact and carry out several measurements.

This pilot is made possible in part by a contribution from the European Regional Development Fund of the European Union.
