Finding a biomass energy solution that combines power generation with forestry


Volter 40 Indoor with fuel handling and drying solution


Introducing a show-case project where the heat is used for heating greenhouses and electricity is sold to the grid through a feed-in-tariff system, introducing a new forestry based business model for the Miyazaki area

Hamatech Co. Ltd is located in Nishimera village in Miyazaki prefecture, Japan. The company was founded in 2010 and has sales offices in Fukuoka and Tokyo. Hamatech currently employs around 22 people. The company’s plans include extending their operations internationally.

Sustainable and renewable energy production in the Miyazaki area

Hamatech has a history of clean energy production and solar energy in particular, but the sale of solar energy has decreased recently. On the other hand, there are substantial forest resources in Miyazaki prefecture. Making power from wood is a sensible alternative for solar energy. Hamatech aspires to introduce a business model in the Miyazaki area, where companies produce energy from wood; the wood is harvested from their own forests as a silvicultural procedure.

Creating a profitable business model from biomass energy production

The company became interested in producing energy from biomass as they wanted to combine electricity business with forestry. Even if biomass is favoured in Miyazaki prefecture, large biomass installations are not conceivable due to electric company regulations. Hamatech’s idea is to meet the demand with smaller-scale installations. Greenhouse cultivation is a strong field of agriculture in Miyazaki, which creates a natural market niche for Volter CHP systems; the electricity can be sold on to the grid, and the heat can be used for heating the greenhouses. With their first Volter 40 Indoor installation, Hamatech can prove their customers that the concept is working.

Compact design and fully automated operation process with Volter 40 Indoor

Hamatech chose Volter 40 Indoor because of the advanced automation features, easy operation, safety and compact design. Also, the heat recovery was one of their criteria.

“We like Volter 40 Indoor system very much, and in our opinion, it is the best CHP in its scale. Operating by both experts and amateurs is easy. It is compact and alarms the user even in small issues. Since the process is fully automated, the CHP doesn’t require to be looked after 24 hours a day. Although it uses fire, it is safe to operate unmanned, and it doesn’t waste the heat. For these reasons we think Volter 40 Indoor is a safe and superior CHP system.”
Hiroumi Syukuwa, Director, Miyazaki Sales Office 


"From the day we received our Volter 40 Indoor from Finland, we have always been able to count on Volter Japan’s support. Sales team and engineers regularly keep in touch with us by calling or by visiting us and it gives us the sense of security."
