pictureDecember 2015: The Article "Homogeneity of lithium distribution in cylinder-type Li-ion batteries" is published in the Nature Journal

The article deals with structural studies on the graphite anode of different Li-ion cells of 18650-type in charged state performed in combination with electrochemical measurements and X-ray CT revealed non-homogeneity. Discussed are also deviations from a homogeneous behaviour in the frame of cell geometry and electrical connection of electrodes.

Better Energy Systems Thanks to Data AnalysisNovember 2015: The German Research Foundation (DFG) Funds New Research Training Group on Energy Informatics at Karlsruhe Institute of Technology (KIT)

Extension of futureproof energy systems is one of the major challenges faced by society in the next decades. These energy systems will have to be able to flexibly cope with different inputs from renewable energy sources and fluctuating demands. For this purpose, complex computerized solutions will be required. Within the framework of a new research training group funded by DFG, young researchers of KIT will develop methods to evaluate data from complex energy supply systems and identify optimization options. The research training group will start on May 01, 2016.

November 2015: Helmholtz-Energy-Alliance 'Technologies For The Future Energy Grid'

Together with universities and energy suppliers, Helmholtz researchers in the energy alliance “Technologies for the future energy grid” were developing solutions for a flexible and stable power grid that can withstand fluctuating input of electricity from renewable energies. This also involves the use of existing gas networks as energy storage facilities and the interlinking of electricity and gas networks. In Berlin take place the concluding conference to evaluate the results.

Combining Battery and CapacitorOctober 2015: Energiewende: Combining Battery and Capacitor

The concept of the energiewende inherently includes smart energy use. But there is not yet any storage system that could be used by industry to efficiently recover braking energy of the many machines in Germany. A hybrid storage system combining the properties of batteries and capacitors would be needed for this purpose. Further development of these hybrids, called power caps, is now pushed by KIT and its cooperation partners under the FastStorage BW II project that is funded with EUR 25 million by the state of Baden-Württemberg.

Electric VehiclesSeptember 2015: Electric Vehicles Reduce Costs and Protect the Environment

Under which conditions are electric vehicles less expensive than diesel vehicles? What are the positive environmental effects? And what about their acceptance by users and reliability in practice? The RheinMobil project coordinated by KIT answers these questions in a study of a fleet test covering two and a half years of operation with 300,000 electrically driven kilometers. The results were presented at the International Motor Show (IAA) in Frankfurt.

Regional Generation, Use, and Storage of PowerAugust 2015: Regional Generation, Use, and Storage of Power

As a result of the energy turnaround, a large fluctuating amount of renewable energy will be fed decentrally into the power grid. Ideally, it should be used and stored locally to make the extension of the long-distance transmission grid unnecessary. This requires new concepts for power use, conversion, and storage on a local level in cities and municipalities. Karlsruhe Institute of Technology (KIT) now cooperates with partners in the RegEnKibo project to develop smart grid technology and infrastructure for future regional energy supply. The project in the model city of Kirchheimbolanden is now funded by the Federal Ministry for Economic Affairs and Energy (BMWi) with EUR 2.2 million for a period of three years.

Helmholtz Energy Materials Foundry August 2015: New Laboratory Platform HEMF For Energy Research

The Helmholtz Senate has resolved to set up a large-scale infrastructure for the synthesis and development of novel material systems for energy conversion and storage. The total volume will be € 46 million between 2016 and 2020. The creation of the Helmholtz Energy Materials Foundry (HEMF) will be coordinated by Helmholtz-Zentrum Berlin (HZB). Five other Helmholtz centres will be involved in the concept and setup: the German Aerospace Center (DLR), Forschungszentrum Jülich (FZJ), Helmholtz-Zentrum Geesthacht (HZG), and the Karlsruhe Institute of Technology (KIT). The new platform HEMF will also be available to external user groups from universities and non-university institutes both within Germany and abroad, as well as to industry.

Home Storage SystemsJune 2015: Intersolar: Finding Safe and Efficient Home Storage Systems

How do I find the right storage system for my application? This question is asked by many potential buyers. Battery storage systems available on the market differ considerably in terms of safety, price, performance, and, hence, economic efficiency. At the Intersolar, the world’s leading exhibition for the solar industry in Munich, the KIT will now present its latest research findings as to how efficient batteries should be designed and provide information on the reliable assessment of the performance of storage systems.

reactor INERATECMay 2015: INERATEC founded by SCI-Researchers

SCI-Researchers at IMVT in Topic 3 Synthetic Hydrocarbons established the spin-off INERATEC which provides innovative reactor technologies. Core of the novel technology ist a micro structured chemical reactor that was developed within research activities at KIT. INERATEC advance this technology to a marketable chemical compact system. For the first time this system is able to turn small and medium quantities of methane gas derived from fossil or renewable sources and, for example, arise as waste in oil or biogas production, into liquid synthetic fuel - petrol, diesel or kerosene - of the highest quality.

Solar Power StorageApril 2015: Solar Power Storage Units Reduce Costs of the Energiewende

The increasing share of electricity based on solar and wind power results in an increasing load of distribution and transmission grids. At the “Helmholtz Institute Ulm (HIU) for Electrochemical Energy Storage“, the KIT demonstrates how modern high-performance batteries and smart controls make renewable energy compatible with the grid. Expensive and controversial grid extension measures can be reduced in this way. The solar power storage system with a 76 kWh battery unit started operation at HIU today and supplies the building with electricity.

SCIJanuary 2015: New Helmholtz Program Storage and Cross-linked Infrastructures (SCI) Started

The transformation of the energy system in Germany is a long-term challenge facing society. A number of political and economic aspects have to be considered. The central technical challenge consists in extending the existing energy system such that all energy sources can be integrated and transmitted reliably. The new research program SCI of the Helmholtz Association is coordinated by the KIT and aims at developing the technologies required for this purpose. The budget for the project period of five years totals about EUR 310 million.
