This is great news. At this point they are just looking for producing polyethylene without CO2 emissions, and the H2 byproduct is just a bit of cherry on the cake. But pyrolysis can be taken to its logical end where you fully remove all the hydrogen from the hydrocarbon molecule, and only carbon is left, which can then be put in long-term storage (like old mines, or simply landfills). The hydrogen is then burned to get electricity without any greenhouse gas emissions. This is not economical right now, although research is active [1]. But any R&D investments in partial pyrolysis will certainly bring us a bit closer to economical full pyrolysis.
