To the extent the HTR is also applied for electricity alone, this would enlarge the technology base and improve the economics of other HTR energy products, such as process heat and hydrogen. As articulated in EPACT05, the NGNP program did not explicitly address the broader use of high-temperature process heat, but the complementary public/private partnership initiative clearly hopes to extend the HTR to industrial process heat applications that now primarily use expensive natural gas.

The current disconnect between the base NGNP program plan and the complementary public/private partnership initiative must be resolved so that all parties are working to achieve a consistent set of milestones. These elements include the reactor design; the heat transport system design, including the IHX; the fuel design and supply; and the hydrogen generation process design.

Has the Program Demonstrated Adequate Progress in Achieving Its Long-Term Performance Goals? Since the long-term performance goals are not fully established -- for example, the final temperature design for the VHTR is not defined -- it is not possible to judge NGNP program on this criterion yet.

From page 69... ...
Because the high-temperature methods could realize 60 to 80 percent greater efficiency than conventional electrolysis, the NHI program is tightly connected to the NGNP program to develop a reactor capable of providing high-temperature process heat. The mission of the NHI program is to operate a nuclear hydrogen plant to produce hydrogen at a price that is cost competitive with other transportation fuels by 2019.

Given the escalating prices of gasoline and the mounting desire to reduce carbon emissions, the need for these products is likely to grow substantially within years rather than decades. Hydrogen Production Technology Options and R&D Status Current R&D on high-temperature steam electrolysis focuses on solid oxide electrolysis cells, a process that was recently demonstrated on the laboratory scale at Idaho National Laboratory.
