< About Woody biomass power generation >
Last year in 2017, we looked at the first international Biomass Power generation exhibition at Tokyo Big Sight.
As the renewable energy fixed price purchase system (FIT) and power liberalization became the lure of water, the venue was exhibited many power generation related facilities, and the number of visitors was many, especially in the event that the power generation business using woody biomass in various parts of Japan was started. The difficulty of woody biomass power generation of woody biomass power generation is as far as the success case of the business to be able to take profit is close to zero.Looking at this exhibition, the biomass power generation business of the Japan, in fact, was a subsidy project in the past and the present, and it seemed that it was still far ahead to become independent as the power supply which was able to take profit on a roll on a commercial base. In the case of woody biomass power generation, the purchase price of Japan fit is 32 yen per 1kw in unused timber. I hear that this is a case in which a chip of 12000 yen per ton is made a fuel in the 5MW facility by the steam turbine. However, the business operation is difficult though it set the purchase price of 42 yen last year in a smaller power generation facility than this. Therefore, the electric power of the equipment cannot help becoming a large equipment. Large-scale equipment can reduce the cost of electricity, which is more profitable. Many large-scale power generation facilities are exhibited in the venue on this day, and the introduction has been proposed and planned.
However, the reality is severe. If it becomes possible to introduce a large-scale equipment that only the priority of the thermal use than power generation is not recoverable cost high, and the equipment operation, to operate the business, the collection of the current woody biomass resources, and considering various circumstances such as efficient energy use,
The sustainable power generation business is a difficult and unreasonable story even if the subsidy is used. So, what should I do? The answer is one.
First of all, the proper use of woody biomass based on the current situation is not the first form of power generation, and it seems that the priority of thermal use is high solid business profitability. In United Kingdom, we removed woody biomass from fit and started buying a fixed price instead of heat.
