The Question
- Given that on-demand hydrogen can be generated anywhere, why is it so unpopular for on-demand generation of cutting gas? The big guys [1] say that is expensive.
However, if a 50 lb bottle of acetylene is $100 - and electricity is 10 cents per kilowatt hour - we have $100 would cover 1000 hours of such cutting. Assuming that it takes 5kW to generate a cutting flame at 85% electrolyzer efficiency - that is enough for 200 hours of cutting on the equivalent of one tank of acetylene. One tank of acetylene lasts no more than 24 hours in cutting, so oxyhydrogen appears to be a factor of 10 cheaper.
Why nobody oxyhydrogen cuts?
