Gasholders

Safely store and regulate biogas from anaerobic digestion.

GTI is the exclusive distributor of VSO Biogas Technologies’ double-membrane gasholders in the United States and Canada. GTI’s cover experts can deliver, install, and commission these gasholders, and provide advice on how to maximize the use of biogas.

Gasholders are designed to:

  • Regulate and respond to fluctuations in biogas volume
  • Safely store excess biogas for later use 
  • Reduce greenhouse gas emissions
  • Increase profitability by reducing wasted biogas
  • Operate digesters with lower energy demand

The gasholders safely store and regulate the use of biogas, which can be used in engines and combined heat and power (CHP) units for electricity and heat at wastewater treatment plants, municipalities, and farms. Biogas can be also be used in boilers for process heat and steam or, in some cases, sold to a local utility for profit. 

Double-membrane gasholders have an inner membrane to hold the biogas and an outer membrane to protect the inner membrane from the elements and regulate internal pressure. Both membranes are made from flexible composite materials and are assembled using high-frequency welding following strict standards. The gasholders range in size from 1,800 ft³ to 180,000 ft³ (50 m³ to 5,000 m³). Proper operation is managed by a level sensor, pressure relief valves, damper valves, and blowers. Leak detection is also available.
