We go around this issue frequently, as end users often come up with the same idea. It is hard to tell them no, so we always take a fresh look under the circumstances. At the end of the day filtration of CO2 i always ruled out, and that means 40% of the volume of gas you are compressing serves no energetic purpose. Add that to the fact that methane does not like to be compressed, and we arrive again at a "no" response. <br>
<br>The one option we always examine is the non-compressed transportation of large gas reservoirs. This we have tried for distances that are too long for a simple gas line, and short enough to be practical by cart. Since we can make durable gas reservoirs of any size and shape, this is not unfeasible. Once transported, the gas is connected and used as usual, while a second reservoir is filling. If you can create value for this use, and the transport logistics to not out-weight the value of the energy provided, you may have an option for success. Others have used large truck inner-tubes in the same way, that are then rolled down the street to the end use. I suspect that in certain locations, systems that considered low-pressure distribution could gain some traction. <br>

Hello Harold,<br><br>I completely agree withYvonne, it will be economically expensive to compress the gas.<br><br>P.S. Yvonne, could you send me a copy of the paper and ppt as well? <br><br>Best regards<br><br><div style="display: inline;">

<div>hello</div>
<div>Got a question from the owner of a small biogass plant in Tanzania.</div>
<div>He is expanding a small existing biogas plant to be able to digest waste from 200 households and manure from 100 cows. </div>
<div>He is interested in using the biogas for fueling vehicles. In our part of the world we think it will be necessary with cleaning, uppgrading of the gas and compressing.</div>
<div>Do any of you have experience/ideas about whether this is feasible for such a small plant?</div>
<div>1)What is necessary to use the biogas for fueling vehicles and 2) what are the technical and economical consequences?</div>
<div>Thank you</div>
