Its a critically important item of course and so we at Host Bio-energy put considerable thought into this. We utilize double membrane digester roofs which are cost effective and extremely durable. They provide protection from extreme weather and UV rays. They offer several hours of biogas buffering which from an operational perspective is helpful when downstream systems are offline. They are also extremely easy to install and maintain. We can in colder climates up the anti on heat insulation too, helping us maintain optimal temperatures within the digester. Our membrane roofs also has efficient gas collection with minimal losses which is exactly what you need on an RNG project!
