Task 44 published Best Practice examples on flexible bioenergy to showcase the multiple benefits and services that flexible bioenergy can provide. The global coverage of Best Practices aims to highlight different operational environments and how bioenergy can fulfil different requirements. You can explore different Best Practices either through the interactive map or list of Best Practices.
If you know a good example and would like to have it presented as a Best Practice, please contact nora.lange[at]dbfz.de, kjell.andersson[at]svebio.se or miia.nevander[at]vtt.fi. |

E-GAS PLANT, Werlte, Germany In Werlte, green hydrogen is initially produced from renewable electricity by electrolysis. The hydrogen is then converted to methane in a catalytic methanation process using carbon dioxide from a biogas plant operated with residual and waste materials. The plant preferably obtains electricity for electrolysis when there is an oversupply due to high feed-in quantities of wind or photovoltaic power. The final product is grid-ready synthetic natural gas (SNG) in a compressed (CNG) or liquefied (LNG) state. Task 44 Best Practice_e-gas Werlte_Germany |

BIOMASS HYBRID DRYER, Jyväskylä, Finland VTT’s pilot hybrid dryer combines solar collectors and a heat pump in an efficient and flexible way. Various drying modes, such as solar alone, pump alone or solar and pump together, can be applied, depending on the availability of solar irradiation and electricity price. Especially, when electricity is cheap, this dryer is economical. Solar energy can always be utilized to boost the drying process. The control system allows flexibility between different operating modes. Task 44 Best Practice_Biomass hybrid dryer_Finland |

THE ETHTEC LIGNOCELLULOSIC BIOETHANOL PILOT PLANT, Muswellbrook, Australia Production initially of sugars and lignin from lignocellulosic feedstocks, then flexible use of the sugars for production of ethanol, other liquid biofuels, food additives, bioplastics precursors and other biochemicals. Biofuels are flexibly used for transport, agriculture, forestry, mining and electricity generation. Lignin is used for electricity generation and production of biochemicals.

SIEMENS ENERGY ON THE PATH TO DECARBONIZATION THROUGH GAS TURBINES, Finspång, Sweden Siemens Energy is developing a pioneer technology, turbines that can be fuelled with natural gas, biogas and hydrogen. The company works on the development, manufacture and services related to gas turbines as well as on the construction of the entire power plants. The main characteristics of these turbines are high efficiency and low environmental impact as well as low emissions. The integration of hydrogen fuelled gas turbines in future energy systems is demonstrated in the Zero Emission Hydrogen Turbine Center (ZEHTC). Task 44 Best Practice_Siemens gas turbine_Sweden |

WOOD-BASED CHP WITH BIOCHAR PRODUCTION FOR NEGATIVE EMISSIONS, Frauenfeld, Switzerland The otherwise unused wood from forest and landscape management is converted in a pyrolysis type thermochemical process at 850 °C to a gaseous fuel and biochar. While the wood gas is converted in four gas engines to produce renewable electricity for around 8,000 households and heat that is used by a sugar factory and the regional district heating network, biochar is also discharged from the process. Part of the CO2 stored in the wood is permanently removed from the atmosphere in the form of biochar. The biochar is used in agriculture to improve the soil, as a feed additive or as active carbon for water cleaning. Task 44 Best Practice_Biochar Frauenfeld_Switzerland |

PIONEERING INITIATIVE TO PRODUCE RENEWABLE HYDROGEN FROM ETHANOL IN BRAZIL, São Paulo, Brazil The University of São Paulo (USP), Hytron, Shell Brazil, Raízen, and the SENAI Innovation Institute for Biosynthetics and Fibers (CETIQT) have put together a pioneering initiative to produce renewable hydrogen from ethanol and signed a cooperation agreement for the development of two production plants in the city of São Paulo in Brazil. The agreement includes a hydrogen refuelling station (HRS) for a university bus. Hydrogen reforming from ethanol enables local production of hydrogen close to consumption from ethanol that is easy to transport. Thus, the solution creates temporal and spatial flexibility through intermediate bioenergy carrier. Task 44 Best Practice_Hytron_Brazil |

RENEWABLE HEAT SUPPLY IN A BIOENERGY VILLAGE, Mengsberg, Germany The small village of Mengsberg has opted for a state-of-the-art hybrid solution consisting of an open-space solar thermal field, a wood chip boiler, and an on-demand and redundant biopropane boiler for fully renewable heat supply. Mengsberg’s concept is based on the variant of a three-stage heat generation system with redundancy, so that a reliable heat supply to all connected buildings is guaranteed 365 days a year. This is an exemplary step towards minimising dependence on fossil fuels in rural areas. Task 44 Best Practice_Mengsberg, Germany |

BECC – FROM BASE-LOAD BIOMASS CHP TO A FLEXIBLE ENERGY HUB, Land van Cuijk, the Netherlands
BECC, Bio-Energy Centrale Cuijk, is transforming from a base-load project based on a solid biomass power plant to a flexible renewable energy hub, which is steered on optimizing operational margin instead of maximizing MWh output. |

EMPYRO – BIOMASS TO PYROLYSIS OIL, Hengelo, the Netherlands
This example highlights BTG Bioliquids’ fast pyrolysis technology, demonstrated at a commercial scale of 25 MWth. This polygeneration facility converts 5 t/h of clean wood into 3.2 t/h of pyrolysis oil, while excess heat is utilized to produce steam. The steam drives a turbine for electricity generation, aids biomass drying, and is supplied to a neighbouring company, with surplus electricity sold to the grid. |
