Nuclear Production of Hydrogen, Fourth Information Exchange ...

PRESENT STATUS OF HTGR AND HYDROGEN PRODUCTION DEVELOPMENT IN JAEA
on nuclear energy utilisation, works to show the public easy-to-understand basic information on
future energy supply and demand as nuclear energy vision for 2100. The JAEA hopes to encourage
vigorous public discussion of these issues.
Because it will take more than a century to transform our energy system into a truly sustainable
system by replacing society’s major infrastructure, the time range of the scenario in the report is from
2000 to 2100. The scenario quantitatively examines a variety of technological options on their
effectiveness in reducing emissions and stabilising energy supplies. Most of the options are taken
from the outcomes of JAEA’s own past and ongoing research programmes.
Proposal for low carbon society
The 2100 vision shows that the utmost utilisation of the renewable and nuclear can solve the energy
and environmental problem.
On the demand side, final energy consumption shifts to electricity and hydrogen. Energy
consumption in 2100 will decrease by 42% with development and improvement of the technology
about the transportation field in addition to the energy saving and decrease of the population shown
in Figure 11. As a result of the promotion of electrification, the rate of the power to the total energy
consumption will greatly increase from 24% in 2005 to 62% in 2100 as shown in Figure 12. Hydrogen
will account for 8% of the total energy consumption.
