[Digestion] Digestion Digest, Vol 45, Issue 4

Dr. Karve,

Thank you for your response! (It is really great to hear from you, my whole
team and I really admire the work that you are doing.)

Transportation via a cylinder does make a lot more sense.

Now I am wondering what other kinds of pumps could be used to achieve a
high pressure for storage.

I do know of some Chinese-made biogas pumps that achieve around 4 psi, I'm
wondering if that would be enough for a cook-out and if a more powerful
compressor that I don't know about yet would be able to achieve a higher
pressure (and thus store more gas).

Do you have any suggestions of pumps that can pressurize biogas safely
(besides a pesticide pump)?

Sincerely,
