Wood gasifier in agriculture | References
The wood-based CHP plant with 2 MW electric is located in Azumino, Japan. Particularly innovative: the Japanese large group Air Water Inc. generates electricity and heat from regional wood in the specially built biomass energy center Azumino with the CHP systems from Spanner Re² and uses CO2 by means of a special process to promote photosynthesis in tomato cultivation - a so-called " Trigenereration ”concept, which is unique in this form in Japan.
The agricultural enterprise in Etzenbach near Neufahrn/NB has been generating electricity and heat since December 2011 for the residential building, the calves stable, the workshop and a total of four drying systems for hay and wood chips.
Annual plant availability of the wood gasifier of 98%.
"We are delighted with our 3 Re² Biomass CHP units and would highly recommend them for their reliability and efficiency. The scalability of deployment means the units are suitable for many different types of business models", said Viorel Panait, Energy Manager, Castleton Fruit.
Castleton Fruit were one of the first businesses in the UK to install a Re2 Biomass CHP on their farm located in Laurencekirk, Scotland. They are one of Scotland's largest commercial soft fruit growers producing premium, high quality strawberries, raspberries, blueberries and cherries. The infrastructure required to operate such a successful large scale fruit farm is vast and requires a considerable amount of heat and electricity.
Above San Casssiano lies the property of the Crazzolara family, a dairy farm at 1,600 m above sea level, which has covered its energy requirements with a Spanner Re² HKA 45 since December 2012. Two drying systems for hay and wood chips, two holiday homes, the private home, an external garage with workshop as well as the agricultural building incl. cow barn get their heat and electricity from the Biomass CHP.
“Conventional energy generation with the negative results, independency of costs and the central energy politics made me thoughtful. With the HKA 10 we can produce electricity and heat anytime with our own wood and are independent. A good feeling.”, says Andreas Huber.
Andreas Huber was determined to find an electricity and heat solution for his farm and buildings that was self-sufficient and cost-effective. In 2016, after a long search to find the best technology he invested in a Biomass CHP from Re². The HKA 10 CHP unit produces electricity to cover Andreas´s own needs as well as supplying the power supply system which he receives payment for according to renewable energy law. The heat produced by the HKA 10 is used for heating Andreas´s buildings and also for drying the wood chip.
Organic farmer benefits from heat & electricity from wood chips
Organic farmer Josef Braun from Bavaria’s Freising district is one of the first to operate a Spanner biomass CHP with an output of 30 kWel and 80 kWth. Josef "Sepp" Braun harms 57 hectares of land to produce feed for 22 dairy cows through organic farming. The 85,000 litres of milk are processed at his own cheese dairy, and sold at the farm shop. The heat from the biomass CHP is used to dry 25 hectares of clover, while the electricity is fed into the public grid.
Wood gasifier supplies electricity for hay drying & electric car
At the organic farm Helfer in Pensier, the electricity generated from wood chips is primarily used for hay drying. The electric car of the family as well as a telescopic battery charger and a refrigerated container, which is used in summer to cool vegetables, are also supplied with the green electricity supplied by the wood gasifier.
Like many farms JS Baird & Sons use a considerable amount of electricity and also require a reliable source of heat. Based in Angus, Scotland, JS Baird & Sons operate a mixed farm including arable, organic sheep and cattle, chickens, organic hens and various renewable technologies. Always looking for the most environmentally responsible option, JS Baird & Sons became interested in Biomass CHP technology to generate electricity and heat for their farm.
The Roßmeier family, from the Bavarian town of Bäderdreieck, runs a 30-system biomass CHP, which commenced operation in December 2011. It reached 7,000 operating hours in 2012 and 8,000 in 2013. Along with a farm and boarding house, the family also runs an ostrich farm, marketing the meat through its farm shop. The electricity is fed into the public grid, and remuneration is paid in accordance with the German Renewable Energy Sources Act (EEG).
Farmer Johann Huber generates energy from roadside greenery. North of Landshut (DE) is located Johann Huber's agricultural company. The woodchip heating system installed, there was no longer able to cover the heat demand from 2011. Since Huber cultivates roadside greenery for the community and can thus use this raw material, the new heating system should be used again with wood chips. Huber has a special interest generating electricity from wood. So he installed a wood gasifier from Spanner Re².
Repowering of the wood gas CHP from 30 to 55 kWel
Due to an increasing energy demand Huber replaced his old wood gas CHP with a new one in 2018, increasing its plant output by up to 50 %.
