ELECTRICITY AND HYDROGEN PRODUCTION

Electricity and hydrogen product rates per each 600 MWt-reactor plant... 

Today, different processes (steam reforming, autothermal reforming, partial oxidation, gasification) are available and commercially mature for hydrogen production from natural gas or coal. These processes would have to be combined with technologies for C02 capture and storage (CCS), to keep the emissions profile low. A power plant that combines electricity and hydrogen production can be more efficient than retrofitted C02 separation systems for conventional power plants.

Generation of photocurrent at the semiconductor/electrolyte interface upon its illumination makes it possible to carry out photoelectrochemical reactions which can be used either for chemical fuel production, or purification of waters. Principles of operation of electrochemical cells with semiconductor electrodes for solar energy conversion to electrical and chemical energy are formulated. Most efficient cells for electricity and hydrogen production are surveyed. Certain processes for photo-destruction of pollutants, recovery of metals, etc. with making use of semiconductor dispersions are briefly discussed. 

Large, Passively Safe, High-Temperature Reactor for Electricity and Hydrogen Production... 

The INL has performed an assessment of both the pebble bed and prismatic fuel type helium gas cooled reactor. This is for the next generation nuclear plant (NGNP) to demonstrate emissions-free nuclear assisted electricity and hydrogen production. These designs will meet the three basic requirements that have been set for the NGNP a coolant outlet temperature of 1,000°C, passive safety, and a total power output consistent with that expected for commercial HTGRs.
