The biogas food digestor at ISK is not being used. Biogas can be used in many ways, although the area that the digestor is in doesn't allow for easy use of the methane it produces. It would be challenging to use the methane at ISK. The amount ISK spends buying gas from the station every week or month isn't too costly, so switching to a biogas system wouldn't be beneficial. Not only would ISK need many more digestors, which are expensive, but we would also need them to be much closer to the kitchens; ISK would need to make space for them, meaning additional costs. The idea was to transport the gas to areas in need or use it around the ISK. This would be done by filling up a secondary smaller balloon/bladder with biogas and transporting the smaller bag. One issue is that the bladder is difficult to transport because it can pop easily and is too bulky.
Biogas Digestor
We tested the portable bladder. Seeing how long the gas lasted and if the flame was strong enough. Pressurizing the bag was fundamental, before, the flame was weak and barely provided enough heat, but with the pressure the flame was much stronger and hotter.
This system allows for pressurising the bladder so gas will come out in a steady flow. This was done by having tiles or blocks on the top to weigh down the bag. This box can be moved and transported without the bag popping.
