Japan Industry and Policy News: Practical use of the next generation microalgae-derived bio-fuel

ISUZU MOTORS Co. Ltd. and EUGLENA Co. Ltd. aiming at practical use of the next generation “Midorimushi” microalgae-derived bio-fuel by 2018 with the “DeuSEL” project

(21/07/16). ISUZU MOTORS Co. Ltd. and EUGLENA Co. Ltd. are joining efforts in the joint projectDeuSEL [1]  aiming at the practical use of the next generation bio-fuel in 2018. The project is divided by 2 main different roles depending of the Company, and various stages (Table 1):

  • EUGLENA Co. Ltd.: R&D for cultivating the euglena microalgae strain, its treatment for obtaining dried biomass and the process for extracting the Midorimushi bio-fuel.
  • ISUZU MOTORS Co. Ltd.: logistics and distribution of the Midorimushi bio-fuel in service stations, and specially, the validation of the Midorimushi bio-fuel using diesel-based buses.

The project consists of a series of tests using the Midorimushi bio-fuel on the DeuSEL bus. To date, the project passed successfully a two-year experiment with a mileage of over 40,000 km. DeuSEL can use the existing diesel infrastructures such as (1) storage tanks, (2) the regular service stations for diesel vehicles and (3) trucks for transportation of fuel.

By using the Midorimushi bio-fuel there are 4 main assets; (1) it helps to tackle the current high dependence on fossil oil imports by enhancing the production of local microalgae-based bio-combustibles, (2) the CO2 emissions are significantly reduced when compared with conventional fuels [2-3], the energy security is improved [4] and it is shaped a sustainable business model through microalgae as it is depicted in the next carbon cycle (Figure 1).

Furthermore, the DeuSEL project created an interactive “HaKoBu” [5] community web in order to (1) enhance the awareness among the potential future customers about the importance of using the Midorimushi bio-fuel and   (2) for detailing how the proposed carbon cycle works, as 2 keys for success.

EU-Japan Centre Comments:

  • The project sets up an cutting-edge R&D initiative without precedent for the validation of bio-fuel derived from euglena microalgae strain using existing standard diesel-based infrastructures (tanks, transportation and stations) and vehicles (in this case, a bus).
  • The project should conclude its validation by 2018. However, it is not revealed if by that period it would be introduced commercially in the Japanese market.
  • The Midorimushi bio-fuel is not yet economically viable when compared with the fossil oil, but it is expected that the costs of production should be going down as the developed technologies are being improved.
