New digestate storage facility with double membrane gas storage at Bioenergie Huber GbR

    A state-of-the-art double membrane gas storage tank from AGROTEL CenoTec was installed at the biogas plant of Bioenergie Huber GbR in Halsbach – including a patented airflow system for maximum efficiency and safety.

    The project at a glance

    High-performance gas holder with 50 % spherical shape

    In 2024, Bioenergie Huber GbR in Halsbach carried out significant extensions to its biogas plant. In addition to the commissioning of a new combined heat and power plant, a modern fermentation residue storage facility with an integrated double membrane gas storage tank was also built. The high-quality gas storage cover was supplied by AGROTEL CenoTec - a further step towards sustainable and efficient energy generation.

    The new gas storage facility impresses with a diameter of 40 metres and a particularly high storage volume - achieved thanks to the innovative 50% spherical shape. In addition to the large storage volume, the shape also enables a high degree of flexibility in the event of operational fluctuations. Thanks to a sophisticated supporting air system, the gas storage tank is statically stable at all times.

    Patented airflow system for precise control

    The Airflow system patented by AGROTEL CenoTec is a technical highlight. It ensures optimum control of supply air and exhaust air (support air) between the inner and outer membrane. The system not only ensures even pressure distribution, but also permanently protects the membrane from material fatigue - an important contribution to the longevity and operational safety of the gas cylinder.
    The gas cylinder fulfils the highest standards of safety and material quality. The inner and outer membranes are stable, tear-resistant, high-frequency welded and UV and weather-resistant. The material is also fire-protection treated - a crucial aspect for the safe operation of biogas plants.

    FAQ`s

    A double membrane gas holder is a flexible gas storage system for biogas plants. It consists of an inner and an outer membrane. The inner membrane stores the biogas, while the outer membrane serves as weather protection and static cover. A patented airflow system precisely regulates the supporting air between the membranes – for optimum stability and safety.

    The storage tank impresses with its high storage capacity (e.g. 50 % spherical shape for more volume), extremely robust materials, UV and weather resistance and fire-treated fabric. The patented air control system ensures durability and efficient operation. The system is also low-maintenance and economical in long-term use.

    The AGROTEL CenoTec double membrane gas holders are customised and can therefore be used individually. They are suitable for agricultural biogas plants as well as industrial plants and are ideal for new installations and for retrofitting existing fermentation residue storage facilities.

    The airflow system patented by AGROTEL CenoTec regulates the supply and exhaust air between the inner and outer membrane. This ensures even internal pressure, protects the material and prevents uneven loading – a key factor ft he service life and operational reliability ft he storage tank.

    The decisive factors were AGROTEL’s high quality, technical expertise and innovative storage solution. The new gas storage facility in Halsbach offers maximum safety, high efficiency and is an important building block for the sustainable energy production of Bioenergie Huber GbR.
