Development of new biomass mixed fuel
KYUSHU ELECTRIC POWER CO.,INC.
Outline
This project relates to the development of an alternative fuel to fossil fuels in an effort to achieve both environmental load reduction and economic efficiency. Coal-fired power generation is very efficient in economic terms but results in relatively high CO₂ emissions. Therefore, the development of a new biomass mixed fuel by using large deposits of brown coal (low-grade coal containing water and many impurities) and unused wood biomass will help achieve CO₂ emission reduction and fuel resource security.
Description
Japan has set targets of 26% greenhouse gas cut by 2030 and 80% cut by 2050, and reducing the amount of CO₂ generated by thermal power generation is an important issue.
With support from the Japanese government* and in partnership with Nippon Steel Engineering Co., Ltd., our company has been developing a new biomass mixed fuel by using brown coal and unused wood biomass since October 2018, and in April 2019, a memorandum was signed with Victoria. Australia regarding technological development using wood biomass resources and the utilization thereof.
Coal is very efficient in economic terms but generates a large volume of CO₂. Therefore, the expansion of the use of biomass is one of the key methods for reducing the amounts of CO₂ emitted from coal-fired power plants. Brown coal, low-grade coal, has advantages in that it is available in large deposits and it is low in ash and sulphur. Meanwhile, brown coal has a high spontaneous heating character , which makes storage and long-distance transportation difficult, and it is used only locally. By using this brown coal together with unused wood biomass, we are producing a new biomass mixed fuel locally, and transporting it to Japan safely so that we can establish and implement a technology that utilizes this new fuel as a fuel for power generation.
By developing a technology for producing a new biomass mixed fuel that is as manageable as coal for thermal power generation, we aim to achieve both CO₂ emission reduction and energy security.
* The project is commissioned by “New Energy and Industrial Technology Development Organization (NEDO)”
