Werlte plant 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.

Hybrid dryer 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.

LIQUID WIND AND ÖVIK ENERGI – THE FIRST E-FUEL FACILITY, Örnsköldsvik, Sweden
Övik Energi will partner with Liquid Wind to provide CO2 for the first commercial-scale eFuel facility. Biogenic CO2 emissions from the energy facility will be captured and combined with renewable hydrogen to form liquid carbon neutral fuel. The fuel will be used by the marine industry to enable carbon neutral shipping. The site is located on the north east coast of Sweden, where Liquid Wind will also have access to the low-cost renewable electricity needed to produce the eFuel.

Australia - Ethtec 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.

POWER-TO-GAS INTEGRATED WITH WASTE-TO-ENERGY, Vantaa, Finland
Vantaa Energy Ltd has initiatied planning of a Power-to-Gas (PtG) facility in its Waste-to-Energy (WtE) plant. PtG plant will produce synthetic natural gas (SNG) from green hydrogen and unavoidable carbon dioxide, captured from the WtE process. PtG facility will be connected to city’s extensive district heating system. In addition to utilization for heating during peak loads, SNG will be utilized as transportation fuel. The concept is designed to fit on foreseen energy markets where supply from variable renewable energy sources decreases electricity prices but increases volatility, and utilization of fossil fuels to cover peak load periods of local district heating system is not allowed anymore, or is very expensive due to tightening climate actions.

Siemens plant 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).

Frauenfeld factory 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.

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.

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.

PELLET PRODUCTION LINKED TO COMBINED HEAT AND POWER PLANT, FALUN, SWEDEN
The city of Falun has an extensive district heating and cooling system and most of the energy is generated at a CHP plant, which mainly uses woodchips as fuel. Falun works closely with the nearby town of Borlänge, and the two towns are linked by a 20 km hot water pipeline that connects the two heating networks and enables cost-effective utilisation of heat and fuel throughout the seasons. The base load of heat production for the two cities is a combined heat and power plant in Borlänge that uses municipal waste as fuel. The solution is based on technology that is readily available on the market, and can be applied in most district heating systems.
