large scale wood gas project in japan

Another large scale project with biomass power plants from Spanner Re² GmbH goes on grid in Japan and also protects the population from allergies by reducing sickle fir pollen. With around 1.8 MW of electricity, it is one of Spanner Re²'s largest projects and once again demonstrates the know-how of the market leader.

Spanner Re² GmbH, based in Neufahrn in Lower Bavaria, has once again implemented a major project in Japan. A total of 28 biomass power plants including the entire periphery such as conveyor unit, discharge and fuel dryer were installed in Japan. With an electrical output of around 1.8 MW, supply the region with electricity from renewable energy sources and do so in a CO2-neutral manner. The generated heat output of around 3.3 MW is used for strawberry cultivation in greenhouses. The Biomass power plants are connected in a so-called cascade and generate electricity and heat from wood according to the principle of combined heat and power. A major advantage compared to conventional large-scale plants is that individual modules can be switched off for maintenance work, but energy production is still ensured.

Customer receives payment for feeding electricity into the grid

In Japan there is a special remuneration system for renewable energy (government FIT system). In this system, the customer receives a subsidy for feeding electricity from his wood-fired power plants into the grid, which represents a significant source of income for him.

Protecting the population from allergies with the help of biomass power plants

One of the most common allergy triggers in Japan is pollen from the sickle fir ("Japanese cedar"), a type of cypress. This pollen poses a health problem for the population, which is why the utilisation of this type of wood is being promoted. In the latest Japanese wood gas megawatt project, wood chips from this cypress species are used to generate energy, thereby reducing pollen. The fuel is dried on site with some of the heat generated.
