Innovative solution that improves the feasibility of land-fill gas and other CHPs

ETW Energietechnik GmbH developed a new equipment that blends two gas streams of different qualities to fuel CHPs. This equipment precisely blends the two gases to a homogeneous fuel mixture and is indicated for landfills that struggle with shrinking heating values and volumes of biogas along their lifetime. This shrinking heating value can be compensated by gradually enriching biogas with natural gas (NG). The blending is completely automatized and designed to consume the lowest possible amounts of NG. Almost any CHP can easily be upgraded.
There are several advantages for the operator. At startups the CHP receives the perfectly balanced fuel, preventing startup problems caused by low CH4 concentration.
That enables the operation of CHPs even with CH4 concentration lower than 30%, increasing its lifetime and availability, thus its economic feasibility. The CHP can be operated independently from the land-fill gas supply.

ETW Energietechnik GmbH has been developing and producing energy plants in Moers, Germany, since 1997. The company‘s core business comprises the construction and maintenance of combined heat and power (CHP) plants in the output range of 400 to 4,600 kWel. as well as highly efficient Biogas Upgrading plants that produce pure Biomethane out of raw Biogas using a high-end PSA technology.
The company is a one-stop provider: From the transfer of biogas to the feed- in of power into the grid and the provision of heat, ETW also takes care of the construction, commissioning, and maintenance of CHP and Biogas Upgrading plants.
The clientele of ETW Energietechnik GmbH includes large energy suppliers, agricultural plants, municipalities, and industrial businesses of various types and sizes, all of which attach importance to eco-friendly, economic energy generation.
One of the strategic highlights is the implementation of economic, sustainable plant concepts that are planned individually and adapted to the respective
requirements. A qualified service team ensures operational reliability and maximum availability of the plants.
The medium sized, family owned enterprise employs a staff of 80 and is managed by its founder Helmut Weiss and his two sons Marco and Carsten.
