So called hydrogen would lead to more pollution then petrol because because its less efficient then petrol but would be derived from petrol thereby increasing over all petrol emissions and CO2 beyond even petrol. You have to be smoking crack to think sequestration would help or work economically. Cleaning up the petrol piece would make already catastrophically bad economics that much worse its not even a pipe dream. Its economic are worse than petrol's which is pure welfare to the extent that its unnecessarily hollowed out the public sector and been a lead weight on standard of living. Its just there to make it seem like petrol fuel energy has a future. Its kind of like VW again saying they are buying 50 billion in batteries or that the beer company bought 800 fool cell motors trucks. Its all BS. Its like the Iran posturing is meant to signal that petrol fuel energy is still relevant. It isn't. Its over. Its only relevance is its rapid inevitable decline despite more useless transfer payments to run phony headlines trying to say its doing better. Now the new thing is to try got call lithium white petroleum. Again irrelevancy. Lithium isn't the end point. Cheaper chemistries will arrive.
