Double-membrane biogas cover
Biogas stands as a key renewable energy derived from organic waste and slurry. In addition to the standard biogas floating covers, Genap has developed a specialised double-membrane cover, which can be applied in biogas facilities. The cover is also suitable for fermenting silos, where biogas is both produced and stored. This dual-layered cover system for slurry silos is designed and fabricated exclusively by Genap.
Construction of a double-membrane biogas cover
The distinctive dome shape, formed by two layers (membranes), maximises storage capacity while also providing resistance to external elements such as rain, wind, and snow. A fan inflates the space between the two membranes to keep the outer ‘protective’ membrane taut. The inner membrane flexes with the volume of gas produced, acting as a reservoir for the generated biogas. For each biogas covering, we conduct a static calculation to ensure the structure can withstand the snow and wind loads applicable to the specific location, considering local laws and regulations.
- Adaptable gas storage capacity
- Tailored cover solutions including static assessments
- Complete setup with ventilation and a gas level monitoring system
