[Gasification] Compression question

[WJ Seidl]

I've seen the topic of compression of woodgas bandied about on the list for
some time, with the general consensus being that it cannot be "easily"
compressed.
Being new to all this, I pose a question, therefore:

Why can't the gas be run through an (perhaps) liquid-cooled oil-lubricated
cylinder type "air compressor" and into a tank? That would provide
compression of at least 100-150 psi. Tank storage would certainly help
provide for a more "transportable" fuel source for auto use. 
Is it the flammable nature of woodgas that prevents such a trial? Or does it
spontaneously combust under pressure?  If that type of system could be made
to work, couldn't the same thing be done with biogases, such as methane?
I realize that for commercial applications, it is better to compress the gas
into liquid state and pipe it, but we're generally proposing smaller
systems, such as for generators, engines, vehicles etc.

Could someone take the time and explain to this newbie why that won't work?

TIA,
