This is a brilliant idea! Ive been thinking about powering a kiln with hydrogen, couldnt you just generate the hydrogen directly using electrolysis with a hydrogen generator that you build yourself? Like have a pipe running through the kiln with small holes drilled in it to distribute the hydrogen and put a seal around the pipe, you can make your own bricks to build the kiln from clay and sand, then make fired bricks with hydrogen and build with them
@GindaUP A commercial electrolyzer could probably make enough h2 in a matter of minutes, but a small electrolyzer would take a few days. Then there's the challenge of storing the h2- a relatively easy problem to solve for a little kiln when compared to the energy equivalent needed for a vehicle...
@kritsri29 The results were good- pretty much like propane, w/ a nice reduction, great copper reds. That kiln would take about an hour for cone 10. I've done a several firings w/ hydrogen , but not for a while now...
@GindaUP Hey G, I paid about $40. per tank (197 cubic ft. per tank, w/ 300btu / cubic foot. That's enough to fire the kiln once @ cone 10. In comparison, propane has about 2500 btu /cubic foot and gasoline has 114,000+ btu per gallon
dave. what temp did you finally get to ? what i find interesting is that no carbon monoxide is produced. wondering what kind of glaze effects can be created with the absence of carbon/carbon monoxide ? thoughts. can a reduction atmosphere be created ? cheers ! i'll be experimenting with hydrogen sometime soon.
cory Lum Hi Cory, I fired the kiln to cone 10 several times, with excellent reduction and nice glaze results. NOx production is one of the main concerns as far as greenhouse gas, etc.

Thanks for your answer.
Good day!

How much hydrogen do I need to burn in order order to get 1000°C in a 1500m3 Kiln?
soulbobo1 A lot- that is a big kiln!

It might take a while to get enough gas to fire using electrolysis. How much is a tank of that stuff anyway?
how was the result?
