Essay: Opinion: Energy: Focus on Japan: The Next Energy Problem in Japan by Dr. Hiroshi Taniguchi Engineer and Architect Tokyo, Japan Recently, Japan
elected a new member of Diet last December. Especially, the energy problem of
nuclear power was one of the important discussion items for this new Diet
member, because Japan has a very severe situation of power cost increases due
to the current lack of nuclear power generation. An innovational party in the
Diet says that natural power can support a sufficient energy supply in Japan,
but natural power has no stable energy supply due to climate change and season
variations. However, another conservative party in the Diet avers that minimum
nuclear power will be important to keep our energy supply, because the energy
cost has been limited by existing levels but the natural power has a higher
cost than fossil or nuclear power. Fortunately, Japan has elected the many conservative
members of the Diet and the conservative Cabinet will continue through 2015 and
beyond. Now, we try to
re-start the nuclear power supported by conservative Diet, but we have severe
discussion for nuclear accident and underground fault layer. So, some nuclear
power plant may be checked by scientific committee and re-start in near future.
Recently, our import of natural gas and oil has been increased so many level to
the total economic activity. Therefore, Japanese Dollar money is gradually
decreased and Japanese Yen will be decreased its exchange rate. Next, the
natural power supply will be limited by capacity of electric power line and
must be supported by energy storage system of pump-up generation dam etc,
because the natural power of solar has only 12% of annual operation rate and
another power of wind has about 22%. Then, the natural power supply may be limited
by 50% of its total capacity and new natural power will be checked by stable
operation conditions. In the future,
we try to check how to solve the CO2 emission trouble and how to avoid the
temperature increase of earth environment. If we cannot use the nuclear power,
the natural power must be increase and fossil fuel of natural gas, oil and coal
will be limited by minimum level of CO2 emission. Now, the energy use of
transportation is supported by fossil fuel of oil etc., so we must change from
fossil fuel to hydrogen for driving power generation as soon as possible.
However, the hydrogen must be produced by natural or nuclear power, instead of chemical
hydrogen reformer. Today, we find new type of car with fuel cell in which the
hydrogen can be converted to electric power for driving power generation, and
it is possible to supply the domestic electric power from fuel cell of car at emergency
conditions. However, this new car has a very high cost of triple level or over compared
to existing one in Japan. Then, we try to
check how to construct our energy system and how to keep our environmental
conditions of domestic and industrial system. If we have no nuclear power and
try to use the natural power only, the energy cost will be increased as doubled
or tripled with its low annual operating rate. Furthermore, another cost of
electric power line and energy storage system will be increased, because the
electric power must keep our domestic and industrial system with stable conditions.
Today, our total energy consumption is gradually increased, but CO2 emission
must be decreased for keeping our earth environment. So, we try to select which
is better to keep the energy cost or the earth environment, but I think that
the both target may be join together to pick up with us supported by scientific
and engineering development. About the Author: Dr. Hiroshi Taniguchi, a native of Japan, was born to
Sotoeand Chiyoko Hongo in 1930. He graduated from Hokkaido University in 1953,
and three years later he married Yoko Kuroiwa. Dr. Taniguchi subsequently
furthered his studies, completing Doctoral Degree of Engineering at Hokkaido
University. From 1953 until 1962, Dr. Taniguchi was Design and
Development Engineer at Mitsubishi Heavy Industries Co. Ltd., Yokohama
Shipyard; following this he became Associate Professor in the Department of
Mechanical Engineering at Hokkaido University, and in 1979, he was promoted to
Professor. After he retired from this University in 1994, he was given the title
of Professor emeritus, and became Professor in Department of Architecture at
Hokkai Gakuen University. He was also given the title of Honorable Professor of
Zhejiang University in China, in 1985. Numerous honors have been bestowed upon Dr. Taniguchi, including
Technical Paper Award from Society of Heating-Air Conditioning and Sanitary
Engineers of Japan, Thermal engineering Award from Tanigawa Foundation,
Technical Paper Award from Japan Society of Thermal Properties. He has also
been awarded Research Awards from Combustion Society of Japan, Science and
Technology Award from Hokkaido Prefecture, International Award from American
Society of Mechanical Engineers, Contribution Award from Tomakomai City,
Research Award from Energy Conservation Technology Committee of Korea, and
Contribution Award from Hokkaido Prefecture. In addition, Dr. Taniguchi has
published many Japanese books on subjects such as Computer Application,
Radiation Heat Transfer, Quality Control, Thermal and Nuclear Power, Energy and
Environment. He has also published Advances in Heat Transfer Vol.27, Radiative
Heat Transfer by Monte Carlo Method, in English. Not surprisingly, he has belonged to several prominent
associations over the years, including Sapporo Rotary Club, Sapporo Probus
Club, Japan Society of Mechanical Engineers, American Society of Mechanical
Engineers, Society of Heating-Air Conditioning and Sanitary Engineers of Japan,
Combustion Society of Japan, Heat Transfer Society of Japan, Gas Turbine
Society of Japan, Thermal and Nuclear Power Engineering Society, Japan Society
of Energy and Resources, Architecture Institute of Japan, and Professors World
Peace Academy. Dr. Taniguchi has also served in various capacities. In
1969, he became Chairman of Hokkaido Prefecture High Technology Committee and
Chairman of Tomakomai City Environment Committee. Eleven years later, he became
Member of Japanese Government Committees on High Performance Industrial
Furnace, Hydrogen Combustion Gas Turbine, Underground Air Accumulation Gas
Turbine and Oxygen Combustion Power Plant. Additionally, Dr. Taniguchi became Coordinator of Hokkaido
Science and Technology Foundation in 1994. On a more personal note, Dr.
Taniguchi and his wife, who is Professor of Tea Ceremony and loves the Japanese
poetic form of Haiku, have two sons. Masayuki is Chief Researcher at Mitsubishi
and Hitachi Power Systems Co. Ltd., and Nobuyuki is Professor in Department of
Mechanical Engineering at Hokkaido University. With regard to religion, the
family has practiced Buddhism for many years. To relax, Dr. Taniguchi enjoys reading and playing Mahjong. [ BWW Society Home Page ] © 2015 The Bibliotheque: World Wide Society |
