Technology:
IHI successfully
developed a technology for stable culture of algae expected highly to be the
next-generation biofuel for aircraft. The company confirmed that improved algae
proliferated while maintaining the high concentration and reduced the estimates
production cost per liter from 1,000 yen to 500 yen. IHI wishes to reduce the
production cost further to 100 yen per liter to compete successfully with the
existing aircraft fuel by 2020.
Successful stable mass cluture of
Botryococcus outdoors
The most critical problem with alga fuel is mass production
because it is necessary to realize mass culture even in the condition susceptible
to contamination. IHI NeoG Algae, one of IHI’s subsidiaries, succeeded in
stable culture of Botryococcus outdoors for more than half a year, opening up
the road to mass production. The company plans to increase the culture scale by
20 times and conduct the substantiative experiment in a test plant of several
thousand square meters. In Japan, IHI, Denso, and JX Nippon Oil and Energy are competing
in the development of algae to be used for jet fuel for aircraft toward 2020.
Research is in progress to develop algaes for fuel
