Indeed, but they're also touting that the energy component of haber-bosch can come from complete combustion of the charcoal, which is where some (much?) of the economic incentive comes from to pay for 'geologic sequestration'. If a less energy-intensive ammonia process is used, perhaps a simpler hydrogen-generating process would be a better fit. ie, if the heat can't be used directly, is this process an economically viable way to generate hydrogen?
