TOKYO — The
HIT Business Research Group has commenced verification tests for a new
technology using sewage sludge to produce hydrogen.
HIT Business Research Group targets conversion of biomass (disposed sewage
sludge) into hydrogen, as a substitute for fossil fuels, utilizing JBEC’s
proprietary biomass gas BLUE Tower technology.The introduction of BLUE Tower
technology to sewage treatment plants will facilitate supply of hydrogen to
fuel cell vehicles (FCV) and stationary fuel cells (FC), which are forecasted
to increase significantly in the future, thereby contributing to actualization
of a sustainable society and urban development based on a low carbon economy.
HIT Business Research Group has commenced verification tests using sewage
sludge to generate bio-hydrogen at JBEC’s BLUE Tower new technology plant
located at its development center in Izumo City, Shimane Prefecture.
small scale tests have shown that the BLUE Tower technology is successful in
converting sewage sludge into gas with high hydrogen concentration, thereby
confirming the potential of sewage sludge as a raw material of bio-hydrogen.
test runs at the verification plant, methodology and production of bio-hydrogen
will be substantiated and followed by studies for a commercial scale
bio-hydrogen production plant and a model business structure.
of the main features of the BLUE Tower is its use of alumina balls as a heat
carrier. In the pyrolyzer, biomass material (woodchips, sewage sludge, etc.) is
brought into contact with high temperature alumina balls to generate biogases
such as methane.
is further heated by alumina balls and steam, and converted to gas with higher
concentrations of hydrogen. Circulation of the alumina balls is highly
efficient in heating core components and also effective in preventing and
making controllable common plant equipment problems such as blockage caused by
