I am looking to build a digestor for farm use. The gas production will

SR replies   Make sure you consider the pressure / gas feed rate to the engine. Using bladder type gas storage, as you suggested, you will probably need a gas blower to deliver around 150 mm Water Column.

The bladder will have to be protected from wind and animals etc. - ie inside an old container - the volume might be constrictive.

That's the fun in working these things out!

Other means of tackling the storage problem are by 1. budgeting / scheduling the gas use rate with the gas production rate or 2. compress the gas.
