Record size of Group Exhibit
Storage of renewable energies – the key for the turnaround in energy policy
 
   
January 29, 2014
   
A focus point of the Group Exhibit will be the storage of renewable energies won out of wind and photovoltaic. The interest in the topic can be seen in the largest exhibition area since the beginning of the Group Exhibit. 150 expected exhibitors from 25 countries will present their products, services and innovations on 5.000 m² in hall 27.

The Group Exhibit will be adding the theme of Batteries to its 20th anniversary exhibition. “Fuel cells and batteries are the key technologies for the turnaround in energy policy, either in electric cars or for stationary storage. Therefore it is very consequent to open and expand the Group Exhibit thematically. The ZSW will present its activities in the field of batteries and fuel cells along the whole value chain at HANNOVER MESSE 2014.” says Prof. Dr. Werner Tillmetz, board member at the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW), Ulm.

Since the beginning of the turnaround in energy policy the amount of produced fluctuating energy from photovoltaic and wind systems increased. Resulting excess energy can be stored directly in batteries or can be used to produce hydrogen which then can be stored.

NiMH batteries as energy storage
Nilar International, Täby, Sweden will present a modular bi-polar nickel metal hybrid battery at the Group Exhibit. At an excess supply of renewable produced energy, this energy can be saved and later be fed into the electric circuit as required. Additionally the power system stability increases.

Hydrogen as an energy storage solution
Renewable energy can be used to produce hydrogen which thus serves as an energy carrier. The process for the hydrogen production is known as electrolysis. Through electrical energy water is split into hydrogen and oxygen. The therefore used electrolysers will be demonstrated by 15 exhibitors of the Group Exhibit. The produced hydrogen can either be fed into the gas pipelines (Power to Gas) or later be transformed back into electricity using gas turbines or fuel cells.

Filled power gap by combined cycle power plant
GP JOULE, Reußenköge, Germany will present an innovative storage solution: the "Stromlückenfüller" - a model project for a combined cycle power plant power-to-gas-to-power. Hydrogen generated from the excess energy of renewable energies is stored. Depending on demand the hydrogen is then again converted together with biogas from the biogas plant into electricity in a combined heat and power plant and fed into the power supply system. The overall efficiency of the electricity and heat use is up to 95%. The project is currently in the implementation phase. A trial operation is planned for the end of 2014.

Fuel cell vehicles and hydrogen fueling on site
On a 15.000 m² Ride + Drive outdoor area interested visitors can test drive fuel cell vehicles. The Clean Energy Partnership CEP, Berlin will present cars from Daimler, Honda, Hyundai and Toyota. The vehicles will be fueled on site by the mobile hydrogen filling station of Linde.

Visitors have the possibility to inform themselves in two forums within the Group Exhibit in hall 27. The moderated interviews and presentations will additionally be transmitted via live stream online.

The Group Exhibit is located in hall 27 directly next to the MobiliTec, the international leading trade fair for hybrid and electric powertrain technology, mobile energy storage and alternative mobility solutions.
