Waternet, a Wastewater Treatment Plant (WWTP) - The Netherlands
420 trucks provided with Bio-CNG
Households and cargo cars in Amsterdam are now running on green gas thanks to DMT’s biogas upgrading system at Waternet. DMT’s Carborex®MS upgrades the biogas into biomethane which is injected into the national gas grid and used as transportation fuel. This project uses a Total Solutions Provider model including engineering, procurement, commissioning, maintenance, operation and trading.
Green gas in Amsterdam transport sector
As a Total Solutions Provider, DMT was responsible for engineering, procurement, commissioning, maintenance, operation and trading. Currently, DMT will operate the facility for 15 years for Waternet. Part of the biomethane generated from this project is converted into Bio-CNG. This provides clean vehicle fuel for trucks, public transport, and taxis in Amsterdam. This green gas project will reduce carbon emissions equal to 13,2 million kilometres. The result is a significant reduction in the carbon footprint of Amsterdam’s transportation sector.
About the project
Waternet cleans and purifies wastewater for 1.3 million people in Amsterdam and a large part of the provinces of Utrecht and Noord- Holland. DMT delivered a total engineering and design package to process 2050 Nm3/h of raw biogas into biomethane. The design included the purification, conditioning, compression and drying of the gas.
As a greenfield project, DMT was responsible for the development of the entire site. This included ground preparation such as soil investigation, pipework, HDD drilling, power supply, powering the building, fencing, entrance gates and security installation. It also included all the permitting approval process (e.g., environmental, emissions, building, and gas grid injection).
A big step towards being climate neutral
In this Total Solutions Provider concept, the build of the entire biogas upgrading site included installation, civil works, grid injection and fuelling stations. Additionally, DMT is not only responsible for plant performance but also for its biomethane production. Currently, the agreement is for DMT to operate the facility for 15 years.
Project results
In March 2021, Waternet’s biomethane successfully injected into the Dutch national gas grid. This biomethane will provide green gas to households in the metropolitan area of Amsterdam. 14,7 million m3 of raw biogas is upgraded into 9,7 million m3 of biomethane using the Carborex®MS. This is equivalent to 10% of the total amount of green gas used by the national grid in the Netherlands.
While part of the biomethane is injected into the gas grid, the remaining is compressed into Bio-CNG. Trucks, public transport, and taxis use this green gas as clean fuel. By transitioning to green energy, this project will reduce carbon emissions equal to 13,2 million kilometres. The result is a significant carbon footprint reduction for Amsterdam’s transportation sector. This is good news as the world nears the historic record for the highest CO2 concentration in the atmosphere.
