Seasonal hot water storage tanks for buildings

Storage systems can stay outside

Hot water storage tanks are mostly installed in homes to provide domestic hot water heating and buffer storage for space heating. However, large storage systems that can store solar thermal heat for months take up considerable space in buildings. Researchers have therefore pursued a new approach: they have designed a hot water storage tank that is placed outside. It is particularly efficient thanks to innovative thermal insulation and special charging and discharging.

Interview with Professor Dr Ulrich Wagner

"Power-to-heat and thermal storage are of utmost interest"

In the merit-order study, researchers at the Research Center for Energy Economics (FfE) and 13 industrial partners jointly examined the nature of an economic system infrastructure for reliable energy supply until 2030. Professor Dr Ulrich Wagner, scientific director at FfE, speaks about the study in this interview. He explains the role of functional energy storage systems, and which storage options were most suitable in which situations.

Long-term heat storage systems

Exploratory drilling in the deep subsurface

On Monday the GFZ German Research Centre for Geosciences started research drilling on the campus of the Technical University of Berlin in Charlottenburg. The data collected is intended to clarify whether Berlin’s substratum is suitable for storing heating and cooling energy. The study is being accompanied by extensive wellbore measurements and laboratory tests.

PEM electrolysis

Prototype has been running for 1,000 hours

Hydrogen will become increasingly important in future for supplying energy because it enables large, renewably generated energy volumes to be stored for longer periods. Together with partners from science and industry, scientists from Forschungszentrum Jülich are developing methods for producing hydrogen by electrolysing water as part of the Ekolyser project. They have tested more robust and cost-effective materials in a new test facility. The prototype has now reached its intended lifetime of 1,000 hours. It is planned that the developed technology will be ready for operational use on a broad scale by 2020.

SmartRegion Pellworm

Renewably stored electricity for the island

Wind energy and photovoltaic systems do not always generate power when it is needed. Schleswig-Holstein is therefore testing the local storage of renewably generated electricity on the North Sea island of Pellworm. The SmartRegion Pellworm project has now won first place in the German Renewables Award competition.

Electricity storage systems in the cloud

green2store: Field test started

The green2store project shows how energy storage systems can be bundled together in a virtual cloud. For the next twelve months, a local network storage system and nine home storage systems will be interconnected with one another in a cloud. The field test has now commenced...

Greater current density for zinc-air batteries

Rechargeable zinc-air storage systems have yet to achieve satisfactory charge and discharge cycles. This provides the starting point for the ZnPLUS project: researchers have increased the current density by using a modified zinc slurry. This makes the batteries easier to maintain and improves their performance reliability – with simultaneously lower costs...

Vanadium Redox Flow

Large-scale storage system begins operation

In the Smart Power Flow project, scientists are testing the use of a large vanadium redox flow battery in a local low-voltage grid. The local storage system recently commenced operation in Tussenhausen in Bavaria. ...

Vanadium redox flow batteries

New design reduces costs for bipolar plates

Redox flow batteries have a relatively complex structure and are prone to error. Researchers have therefore now integrated a bipolar plate directly into a stack. This saves on components and at the same time reduces costs. In addition, it makes the system easier to assemble and more reliable.

World’s largest electrolysis plant

Energiepark Mainz inaugurated

At Energiepark Mainz, Linde, Siemens, RheinMain University and the Stadtwerke Mainz municipal utility company are producing large amounts of hydrogen by renewable means. Four adjacent wind turbines take over the largest part of the electricity generation. The hydrogen can be stored on site, transported in tanks or fed into the natural gas network for the subsequent generation of electricity or heat. The world's largest electrolysis plant of its kind has now been inaugurated...
