Just read @Matt thread on gas storage and thought there was some interesting cross over between the subjects.
A home steam gasification vessel operated in batch mode, feeding a gasometer with 20MJ/m3 gas, (without a blower) is certainly an interesting way to solve the energy storage issue for reliable domestic systems without using a battery bank or long run time engine/gasifier.
Let’s see;
** You get to skip the charcoal making problems of open flames, smoke, grinding, screening and heat recovery (assuming char-gas for small engines).
** You get access to all the low value biomass otherwise unusable for gasification.
**The higher energy content gas means you get to use a smaller storage unit.
**You get built in gas cleanup
**You have a reservoir of engine grade fuel gas (super convenient)
All for the low low price of an untested pressure vessel and it’s regulation and controls:)
Yes, we just re-invented ‘town gas’, but hey..
