Hello all. First of all, greetings. I’m a bit of an interloper on this forum, having no active involvement with the topic, but I always enjoy learning something new about paths not taken or less ‘modern’ because one way or another the waves of industry passed them by. I’ve sometimes wondered how different history would be if the modern insights in permaculture, land management, and simple but efficient cumbustion had been the historical breakpoint before the industrial revolution. Perhaps we would be little less centralized and little more self sufficient than we are today. Congratulations on one of the more truly unique communities on the internet.
Back on topic to my post: I am aware that the major reason that woodgas cannot be compressed and stored is that various trace gasses( primarily CO2 and methane) compose such a large portion of the gas, while possessing such a low compressibility, as to make make it a largely pointless exercise( without even considering the inherent risk of giant ‘kaboom!’). However, I also know that passing steam over/through a bet of hot char/coals produces a gas with a much more goodly amount of hydrogen; from what I can discover with my Google-fu, the percentages seem to range around the lower 60 percents of the final gas). So I was wondering( for my own curiousity, and perhaps one day, a bit of writing) if anybody has here has run the numbers or even does or knows on anybody who has done the experiments to find if the gas poduced from a simple, ‘built at home’ version of such a process is low enough in trace gasses with negative properties for compression and rich enough in hydrogen that this gas could be highly and safely enough compressed that it might be practical to compress and store it for use on motor vehicles( yes, I am aware that hydrogen can be produced via steam reformation of biogas, but then with a few modifications that biogas itself can be used to power and engine, so that largely defeats the point). What is the composition of the gas produced by such a process, and what are it’s properties?
Thanks in advance; And a very merry Christmas to everyone on the board!
