 Is using hydrogen in your home a new thing? My name's Mark Pescovacius and I'm Associate Professor here at Curtin University. Using hydrogen in your home is not actually a new thing. Back before the 1970s in Perth, we used to use something called town gas. That was a gas that was rich in hydrogen but contained other things like carbon monoxide. It was produced from coal and it was quite a dirty source of hydrogen. We then transitioned across to natural gas, which is methane, and now we're thinking about moving to hydrogen. Around Australia we're starting to blend hydrogen back into the natural gas pipelines but they can't take too much hydrogen without causing some damage to that pipework. Here at Curtin we're researching new ways to code pipelines to protect it from this large concentration of hydrogen.
