SUNFIRE GMBH, DRESDEN

The Dresden-based sunfire GmbH, which was founded in 2010, develops and produces high temperature electrolysis cells (SOEC) and high temperature fuel cells (SOFC). High temperature fuel cells made by sunfire permit the particularly efficient production of electricity and heat according to the combined heat and power principle. Decentralized, combined heat and power in the low power range is considered to be the energy concept of the future because electricity and heat are generated according to the actual demand and right there where they are needed. High temperature electrolysis splits water vapor into hydrogen and oxygen. It is operated with renewable electricity. The resultant hydrogen can either be efficiently converted into fuels with sunfire’s power-to-liquids process or directly used in the H2 mobility as well as industrial sectors. 

AXXELLON GMBH, LICHTENSTEIN / SA.

Headquartered in Lichtenstein near Zwickau, the AXXELLON GmbH develops and produces high performance lithium batteries for industrial and automotive applications. The product portfolio of the company, which was founded in 2009, ranges from individual electronic components all the way to complete high performance batteries. Specific competences are available in the battery management systems and the associated power electronics sectors. In addition to an innovative vehicle battery, AXXELLON has also designed and developed a stationary energy storage system for energy coming from photovoltaic plants. With a capacity of 20 kilowatt hours, the storage system is suitable both for isolated and mains parallel operations. It is possible to not only integrate the PV plant, but also wind turbines, combined heat and power plants, emergency power generators, and fuel cells into the system.

HAASE GFK-TECHNIK GMBH, GRÖSSRÖHRSDORF

Located in Großröhrsdorf, the Haase GFK-Technik GmbH produces storage tanks and hot water tanks built with glass fiber reinforced plastics (GRP). The material is resistant to ageing and corrosion and exhibits low thermal conductivity. Thermal energy coming from such energy sources as solar plants, solid fuel boilers, or heat pumps is stored inside the tank and, if so required, used to heat up drinking water or to support the heating system. Water serves as a storage medium. Depending on the individual container size, it is, thus, possible to bridge a longer period of time during which no additional energy needs to be fed into the system. The storage tanks, which have a volume of up to 100,000 liters, can be installed both above ground and below ground. Thanks to a specific assembly technique, the tanks can also be mounted in spaces that are difficult to access. 

DBI GAS- UND UMWELTTECHNIK GMBH (DBI GUT), LEIPZIG

Located in Leipzig, the DBI Gas- und Umwelttechnik GmbH (DBI GUT) addresses the integration of renewable energy carriers into the natural gas grid as well as underground gas storage facilities. Its current focus is on analyzing gas supply systems; developing concepts for energy storage technologies, particularly power-to-gas; and evaluating the feeding of hydrogen into gas grids. In the fuel cell technology sector, DBI GUT develops fuel processors for fuel cells. Basic fuels include natural gas, liquid gas, biogas as well as their mixtures.
