Recent reports of a telephone conversation between the presidents
of the USA and Iran suggest the possibility of constructive future
discussion, including Iran's plans to develop nuclear electric
power. While the diplomacy of Iran's new president is very positive,
the behavior of his predecessor was a definite cause for concern
across much of the Middle East and beyond. Iran is not the only
Middle Eastern nation that seeks to generate future electric power
from nuclear energy. Several other Middle Eastern and North African
nations seek to do likewise and all using uranium-based fuel.
Much has been written previously including at Energy Pulse, on the
more peaceful aspects of thorium-based nuclear power. Previous
research suggests that thorium can be more easily reprocessed than
uranium and that it is quite unsuitable for use in a nuclear
explosive device. The ore that contains thorium occurs quite
naturally in nearby nations such as India, Turkey and Egypt. Earlier
research has also suggested that a relatively small amount of
thorium can generate as much electric power as some 50-times the
amount of uranium.
Constructive political dialogue with Iran could open the door for
possible discussions about using thorium-based nuclear electric
power. At present, much research is under way in China, India and
the USA to develop thorium-based nuclear electric power. Chinese
researchers have been working on high-temperature, gas-cooled
reactors capable of processing thorium fuel. Any willingness by Iran
to discuss possible future thorium nuclear power may go far in terms
of easing political tensions across the Middle East. Iran may
require foreign investment to consider a conversion from uranium to
thorium fuel for their future nuclear electric program.
Any easing of economic sanctions against Iran may likely open a
possible door to discuss future prospects for thorium nuclear
electric power in that nation. Despite having been economically
isolated, Iran has connected long-distance electric power lines
across international borders into Turkey and into Turkmenistan.
Improved diplomatic relations between Iran and other Middle Eastern
neighbor states could possibly result in an undersea power cables
connecting under the Strait of Hormuz or under the Persian Gulf. The
undersea distance between SE Iran and NW India is much shorter than
the proposed undersea cable distance linking British Columbia and
California.
Mutually cordial diplomatic relations prevail between Iran and China
and could open the door to possible discussions about Iran possibly
using Chinese thorium-nuclear technology to generate electric power
for domestic use as well as for export. Iran's geographic location
in regard to time zones allows long-distance power lines to carry
electric power to different time zones located to the east and west
of Iran. The AM peak demand for electric power would occur in a
sequence beginning in India and western China, followed by Iran and
the Middle East, then followed by Eastern and Western Europe.
The Desertec Group has previously discussed prospects east-west and
also north-south long-distance power transmission across Asia, North
Africa, the Middle East and Europe. Except that Desertec focused on
renewable energy such as wind and solar power. Several European
countries that include Spain, Iceland, Ireland, Greece and Portugal
had previously invested heavily in renewable energy, believing that
a Green Energy revolution had the potential to rebuild national
economies. Except that the economic promise of cost-competitive
renewable green energy has faded in several nations. Plans to
install solar collectors and panels across the Sahara and Arabian
deserts are now on-hold.
Energy Storage:
Given the seasonal cyclical nature of the demand for electric power
across much of the Middle Eastern, the Near East and Western Europe,
future development of nuclear power may benefit from the
availability of seasonal energy storage capability. Beginning some
5-years ago, a research team at MIT and a British research group
named Isentropic Energy independently explored future prospects for
seasonal high-temperature geothermal energy storage. There is
definitely potential to develop such storage in the Middle East,
given the availability of a few exhausted natural gas wells that
were flooded with seawater to displace residual natural gas.
Seawater is also used to displace oil from some oil wells, leaving
future potential for some form of geothermal energy storage.
However, high-temperature geothermal energy storage would require
the physical presence of a thermal power station in close proximity
to the energy storage site. The Middle East does have potential for
pumped hydraulic storage with an installation operating in Iran, as
well as potential for compressed air energy storage (CAES) with the
added option of seasonal, water-displacement CAES. Across the
oil-producing Middle East, large salt caverns and salt domes occur
deep underground and also in high mountains.
Salt domes in Muscat and in Iran protrude above ground in high
mountains, allowing for excavation of massive volumes of rock salt
that may be replaced by seawater. A fabric tent cover placed over
the top of the mountain salt dome would reduce evaporation from the
upper reservoir of a seasonal water-displaced CAES system. One of
more salt domes located at great depth and partially flushed of rock
salt would serve as compressed air storage reservoirs. During winter
seasonal recharging, compressed air pumped into the lower elevation
chambers would displacing seawater or brine into the upper
reservoir(s).
Conclusions:
The cost of further, prolonged armed conflict across the Middle East
would be unproductive. Given the US$5-trillion estimated of the Iraq
involvement, it would cost far less to assist Iran to convert their
proposed nuclear-electric program from uranium to thorium fuel that
would produce far less toxic waste that would be quite unsuitable
for use in an explosive device. The future of peaceful nuclear
electric power would depend in the nature of future
inter-governmental discussions between the Iran and USA as well as
other relevant nations
