Technology:
Chiyoda Corp. developed a technology necessary to put hydrogen power generation to
practical use. The company has already been having business negotiations with
several energy-related companies both at home and abroad, and the world’s first
hydrogen power plant is expected to start operation in a few years at the
earliest. Hydrogen power generation does not emit carbon dioxide. On top of
that, Japan is self-sufficient in hydrogen. The company plans to apply the new
technology to the provision of hydrogen fuel for fuel-cell electric vehicles.
Hydrogen
can be used as fuel for gas turbine power generation, but it is hard to store
and transport hydrogen because hydrogen easily catches fire besides being
bulky. To use hydrogen as fuel for power generation, it is necessary to store a
fixed amount of hydrogen at lower than minus 253 degrees centigrade by way of
liquefaction. Chiyoda Corp. developed equipment that allows storage and
transportation of liquefied hydrogen at normal temperature and subsequently
extract only hydrogen efficiently. The equipment can provide hydrogen to a
small-scale generation plant with an output of 100,000 kW. It will be priced at
around 10 billon yen.
Hydrogen
can be stored at normal temperature should it be mixed with toluene, but it was
very hard to extract only hydrogen from the mixture. The equipment built by
Chiyoda Corp. can extract only hydrogen at such high efficiency of more than
98% with the help of its originally-developed catalytic agent. Hydrogen power
generation costs less than oil-fired power generation, but it costs 80% higher
than gas-fired power generation.
