Hydrogen future pathways

For each hydrogen production pathway and for both states of technology development (current and possible future), the committee developed engineering-economic models to estimate the primary inputs of feedstocks, of electricity or other energy, and of capital equipment for each standard-sized plant and to estimate the resulting outputs of H2 and C02. Within the models, a distinction is made between pathways in which the C02 is sequestered and those in which it is released back into the atmosphere. Additional costs of C02 separation, capture, compression, transport, and sequestration are included for processes in which most of the C02 is sequestered. 

Nonetheless, several assertions can be made about future hydrogen supply. In the long term, to fully realize hydrogen s multiple benefits, it will be important to use hydrogen supply pathways with near-zero emissions of...
