Spanner Re²’s “wood-power plants” generate electricity and energy from all natural wood types. Plant operators can make themselves energy-independent and use the electricity generated to power their electric car.
Powered by wood
Germany, Neufahrn i. NB. Spanner Re² manufactures and sells highly efficient Biomass plants that generate electricity and heat from wood according to the principle of combined heat and power (CHP). The patented technology supplies energy worldwide, independent of weather conditions and fuelled only by wood chips, pellets or briquettes.
Spanner Re² sees itself as a holistic supplier in the wood gasification industry and provides its customers with complete systems that have proven themselves. The portfolio of the medium-sized company ranges from fully automatic wood chip drying plants, conveyor and discharge systems to multiple plants - so-called wood power cascades - and pre-installed container solutions (EnergyBlock). Spanner Re² GmbH has established itself as one of the leading manufacturers of wood-based CHP plants both for individual plants and for the realisation of large-scale projects.
"Selling our Biomass solutions to a major Japanese company with more than 10,000 employees is a great achievement for us and also confirms that our technology is in demand all over the world," says Bernhard Seiler, Head of Business Development and Logistics at Spanner Re². "Our customer wants to further expand its added value and generate energy sustainably and economically. Which is exactly what our Biomass solutions will do while also contributing with our many years of experience in project planning," Seiler continues.
Towards the end of the year, ten wood-fired power plants with a total output of 490 kWel and around 1.1 MWth will be installed in Japan, as well as coordinated conveying and discharge technology and fully automatic wood chip dryers. Moving forward, the large corporation will use the heat generated to supply several greenhouses on site. The electricity will be fed into the public grid in return for payment.
Compared to a single large-scale plant, multiple Re² plants generate energy throughout, as maintenance work can be carried out in parallel. Also, no expensive service calls are necessary for this, as the maintenance work can be carried out 100 percent in-house, even on the series-produced engines. Thanks to the modular design of the wood-power plants, the system can also be easily expanded to include additional plants and adapted to the customer's requirements should these change.
"The project is another milestone for both Spanner Re² and us in the field of large-scale project planning," says Oskar Bartenstein, director of the Japanese subsidiary Spanner KK. "Already at the beginning of the year, the starting signal was given for a major project with 25 wood-fired power plants in Japan - the new order demonstrates the dynamism and the great potential that the East Asian market offers to generate electricity and heat from regionally sourced wood", says Bartenstein.
In 2011, Engelsberg, a part of the market Lauterhofen, invested in a wood gasifier from Spanner Re². After more than six years of operation, the Spanner Re² Biomass CHP “HKA 30“ has provided the bioenergy village a satisfactory income from: producing more than 1.5 million kw of electricity and 3.6 million kw of heat – all from reginally sourced woodchips.
German Bioenergy Village Engelsberg is energy self-sufficient
There has been a woodchip heating plant in Engelsberg since 2006. The whole community have shown a great commitment to regenerative energy generation. With approximately 5,000 voluntary working hours, they built a 1,500-metre-long local heating network that connects to 27 of the 30 houses in the Engelsberg district. "Our wish was to generate not only heat but also electricity from wood," explained Mayor Ludwig Lang and Willi Locker Baumamt, Director of the market town of Lauterhofen. In 2011 Engelsberg went one step further and installed a woodgasifier from the LowerBavarian plant manufacturer Spanner Re2 GmbH. At the beginning of the project, Michael Gottschalk, then mayor of Lauterhofen, said that the woodgasifier fits exactly with us in terms of its output of around 30 kW electrical and 70 kW heat. The woodgasifier is designed to cover the basic heat requirements of households and, together with the 320 kW woodchip heating system, continuously supplies the local heating network with heat generated from renewable sources. The old reserve oil heating system has not been used since the implementation of the combination of woodgasifier and woodchip boiler.

Wood gasification technology
The waste heat in the boiler room is also used in Engelsberg. The woodchips are dried to the corresponding water content in the bunker from below via perforated plates. With operating times of 8,200 hours per year, around 1,200 m³ of woodchips are required, which come exclusively from the Engelsberg catchment area.
Wood gasification pays off
Engelsberg leads by example that sustainable energy production is both ecologically and economically attractive. In addition, the value added in comparison to fossil-generated energy remains with the Engelsberg concept in the region.

25 Biomass CHP units from the German plant manufacturer Spanner Re² GmbH will go into operation in Japan towards the end of this year. In close cooperation with its Japanese subsidiary Spanner KK, Re² is implementing another major project for combined power and heat generation by using wood.
Germany, Neufahrn i. NB. Spanner Re² GmbH, the leading manufacturer of Biomass CHP, has been dedicated to the generation of electricity and heat from wood for more than 10 years. With more than 20,000,000,000 operating hours, the Biomass CHP units have proven themselves worldwide with a verifiable annual availability of up to 99 percent.
“When the company was founded, the market primarily demanded decentralised individual plants. A clear movement and demand towards major projects is now noticeable", reports Thomas Bleul, Director of Spanner Re² GmbH. “The ‘HKA 70’, with an output of around 68/72 kWel and 120/130 kWth, is a good example of how we are further developing our solutions to meet this growing trend. Through cascade systems, the power range can be extended up to 2 MWel, depending on customer requirements", explains Bleul.
Together with its subsidiary Spanner KK, Spanner Re² GmbH has received the go-ahead for another major project. 25 Biomass CHP units with a total capacity of 1.75 MWel and around 3 MWth as well as the entire wood-chip logistics with fuel drying and sieving technology will be implemented in Japan this year. Project planning is already in full swing. In autumn, the peripheral technology and the 25 Biomass CHP units will be installed turnkey ready. The first feed-in of electricity into the public grid is planned towards the end of 2018. The heat generated from wood will be used to supply large greenhouses that require very high heat temperatures throughout the year. “The project is exemplary of pioneering heat utilisation in agriculture", says Akiko Okada, Director, business development of Spanner KK.
It is the fifth Biomass CHP to be located in Japan by Spanner KK. The customer intensively researched about ten manufacturers worldwide and then came to us", says Okada. The price competitiveness of Re²'s multiple plants compared to a single large plant was convincing, but also the continuous high plant availability of more than 90 percent. In contrast to a stand-alone system, a Biomass CHP cascade from Re² ensures a high basic supply even during maintenance work. In addition, 100 percent of the maintenance work can be carried out in-house, including the series-produced engines eliminating expensive assignments by specialists. “The project in Japan shows that Re² has reached the league of large-scale plant engineering", says Bleul. “A project of this size requires know-how, reliable plant engineering and a motivated, well-rehearsed team. This is what we can offer our customers", adds Bleul.
The leading plant manufacturer Spanner Re² GmbH from Germany is launching a new wood-based Biomass CHP on the market. With around 68 kWel and 130 kWth, the plant is highly efficient and generates climate-friendly electricity and heat from wood chips.
Germany, Neufahrn i. NB. More power, lower fuel consumption and new intelligent control software: the innovative Biomass CHP "HKA 70" is the first representative of the new generation of wood-based CHP plants from Re².
With a turbocharged 6.3-litre engine, increased heat utilization and a special cooling process, the tried and tested wood-power-technology has been further developed in a highly efficient manner. As a standard feature, the new Biomass CHP is equipped with a synchronous generator, which means that the plant is started using wood gas instead of electricity. This saves costs and ensures safe plant operation, even with less stable power grids. The innovative Re² control system manages the entire plant operation and optimizes runtime stability. The menu structure is reduced to the essentials, which increases ease of operation and makes the control system particularly user-friendly.
“We are committed to making renewable energies competitive", explains Thomas Bleul, Director of Spanner Re² GmbH. “With our new product, the HKA 70, we were able to demonstrate our many years of experience”, says Bleul. With an electrical efficiency increase of 20 percent, the plant is more powerful and converts the regional energy source wood into electricity and heat even more efficiently than ever before.
What is particularly interesting is that the plant operates with recycled waste wood. At present, tree felling is very frequent due to pest infestation or storm damage. The demand for wood chips on the market is very low so the HKA 70 represents an attractive solution for this and paves the way for the operator to achieve energy independence. As a full-service provider for wood-based power and heat generation, Re² offers all the necessary system components for material processing.
The HKA 70 is economical with brilliantly efficient heat production and high utilization of its own power, even with short running times. For example, the wood-fired power plant is not only suitable for operators who have a very high-energy demand all year round, such as sawmills, heating plants or in the hotel industry. It is, also suitable for seasonally fluctuating energy requirements, such as in the case of wages drying agricultural and forestry operations, which have a service life of 4,000 hours per year.
Due to its modular design, the new “smaller” Biomass CHP plant can be combined to increase output and several plants can be cascaded.

- Capping peak loads reduces the complete energy costs
- In addition, Digital Energy Solutions moves forward with island capability enabling energy self-sufficiency for their customer Spanner Re²
Munich, December 6, 2017 Digital Energy Solutions, a joint venture between the BMW Group and the Viessmann Group, has launched a pilot project to optimize total energy consumption at Spanner Re², the leading manufacturer of wood-based combined heat and power units sustainable power generation and storage. The pilot project is a groundbreaking example of how small and medium-sized enterprises can autonomously generate, store and use "green" energy.
The aim of Digital Energy Solutions and Spanner Re² is primarily to combine the provision of network services with the optimization of the total energy consumption of Spanner Re² and make it more sustainable. Digital Energy Solutions has been analyzing Spanner Re²'s internal energy consumption through real-time visualization since 2016.
In 2017, a system was put into operation to ensure sustainable self-generated electricity. It features a 62 kWp photovoltaic system and a Re² EnergyBlock - a turnkey wood-power system with 45 kWel. The system optimizes Spanner Re²’s own electricity consumption via a battery storage with 280 kW and integrated load peak capping.
The necessary control algorithms were jointly developed and implemented through cooperation with Viessmann as the project partner. All units are connected and controlled by the Energy Monitor developed by Digital Energy Solutions. The Energy Monitor is a software solution that companies use for transparency and monitoring of energy production and consumption. The overall system installed at Spanner Re² also ensures island capacity for time intervals and ensures the company's energy self-sufficiency. This island operation has already been successfully tested, so that the power supply can be maintained in case of power failure.
Ulrich Schmack, Managing Director of Digital Energy Solutions GmbH & Co. KG: "The project is a great success on the way to sustainable energy through the management of storage facilities. This is confirmed by the early approval by the network operator Bayernwerk - even before official recommendations for action were formulated and published by the Federal Association of the Energy and Water Industry (BDEW). We clearly see ourselves as pioneers in this area and want to fulfill this role in the future as well. Digital Energy Solutions manages entire systems in such a way that the customer achieves the optimum of revenues through network services and cost savings through self-consumption optimization. "
In 2018, Digital Energy Solutions will accelerate the integration of charging stations into intelligent load management and the integration of electromobility solutions into the overall project. This allows Digital Energy Solutions to take its customer Spanner Re² one step closer in the direction of sector coupling, the connection of electricity, heat and mobility in a complete electrical system.
Bernhard Seiler, Head of Overall Systems at Spanner Re² GmbH: "The project represents a decisive step towards more self-sufficiency in energy supply. Such concepts can significantly improve security of supply, especially in regions with a sensitive energy infrastructure, for example in rural areas where we significantly reduce the risk of undersupply. "
The Canadian community Kwadacha is not connected to the national grid. Until recently, the electricity was produced exclusively by diesel generators. With the EnergyBlock from Spanner Re² GmbH, electricity and heat production now occurs in a climate-friendly way. The new energy source is wood, which is grown by the local forest management.
Neufahrn i. NB. / Kwadacha. The compact, space-saving container-variation of the EnergyBlock from Re² provides flexibility and autonomy. Three Biomass CHP´s each with a performance of 45 kWel and 108 kWth are plugged into the complete turn-key solution. The EnergyBlock can be operated both “On-“ and “Off-Grid”, providing independently generated energy from an existing grid.
“Fort Ware, in British Columbia, is as one of the furthermost distant aboriginal-settlements form the civilization in Canada known. There are very extreme weather conditions with a snow depth of up to three meters and temperatures of -40 degrees Celsius. Of course this was a hardness test for the team of Re² and for our constructions. After the first winter and a plant availability of over 80 percent it showed that our patented technique and our team can also handle challenges like this”, said Re² project leader Bernhard Seiler proudly.
The EnergyBlock is run exclusively with dead wood from the local area. The electricity and heat produced by burning the deadwood, supplies many households, the local school, a community- and guesthouse as well as four green houses. The produce from the green houses eliminate the need for the 400 km journey that locals take to the distant city of Prince George for groceries. “Previously over 150,000 liters of Diesel had to be transported over a 1,000 km distance to fuel the community. It took 10 days, at temperatures of -30 to -40 degrees which was a huge undertaking. With our EnergyBlock the community can use their natural resources and also strengthen the economy”, said Re² director Thomas Bleul. “This Project is exemplary and we are pleased about our achievement of a new milestone in the direction of the future of energy with our proven Biomass technology”, said Bleul.
