Stadtwerke Herne builds energy self-sufficient settlement with redox flow storage system
Published
Stadtwerke Herne is planning to build a climate-friendly and car-free housing estate with an innovative energy concept in Sodingen: seven detached single-family homes are being built in Baueracker, which will be largely self-sufficient in terms of energy. The building permit is expected before the end of this year. The groundbreaking ceremony is scheduled for early 2018. The first families are expected to move in in February 2019.
Whether heating, electricity or hot water - the houses are to produce almost all the energy they need themselves from renewable sources. A large photovoltaic system on each roof and a battery storage system are the basis for this. Geothermal and air-source heat pumps are combined with these. The result is a variety of energy concepts developed by Smart-Tec, the municipal utility's heating service. Smart-Tec also supplies the technology and ensures smooth operation.
PV power: 70 kWp
At the heart of the project is a new type of electricity storage, the so-called redox flow battery. It has extremely low energy losses and can be recharged almost indefinitely. "This concept is unique in Germany," knows Stephan Becker, who is responsible for the project at the municipal utility. This is why the construction project also successfully qualified for the "EnergyEnvironmentEconomy.NRW" lead market competition organized by the state and the EU. Fraunhofer UMSICHT is providing scientific support.
In addition to the energy concept, car-free living is also a special feature in Herne. Cars are parked outside the settlement in a solar garage. "This makes the settlement safe and child-friendly, and there is also nothing to prevent the purchase of an electric car," Becker continues.
The detached single-family homes have a living area of around 120 square meters. The plot size starts at 215 square meters. Building-willing can announce themselves already now under telephone 02323/592-315 or autark-wohnen@stadtwerke-herne.de apply, as a large response is expected. Detailed information will be available after the summer holidays.

A district without cars, in a major German city? In Cologne-Nippes, about 1300 people live in a car-free neighbourhood. The residents of the French Quarter in Tübingen have been gathering experience in a neighbourhood without cars for around 20 years. Does the concept work?
For its fight against light pollution, the city of Fulda in eastern Hesse has been honored as Germany's first dark sky municipality by the International Dark Sky Association in the USA. Fulda Mayor Heiko Wingenfeld (CDU) said: "A large part of light pollution is avoidable, and we want to set an example for other municipalities with intelligent solutions." Light pollution refers to the brightening of the night sky by artificial light sources whose light radiates into the atmosphere.
Daniel Schreiner (independent), the city's planning officer, explained that too much light, and above all the wrong kind of light in cold light colours, has been proven to affect the lives of many nocturnal species, disturb plants and damage people's health. It is easy to use artificial light according to location and need, he said. "In this way, you can avoid light pollution, reduce costs and contribute to climate protection by saving energy."
Following Fulda's application, the International Dark Sky Association awarded the city the title in January. According to the information, Fulda is the fifth municipality in Europe. Worldwide, Fulda is even the second largest city to receive this status.

At a press conference today, Lord Mayor Dieter Reiter, together with City Planning Councillor Professor Dr. (l) Elisabeth Merk, presented an overall plan for Munich's mobility in the coming decades.
Where could new underground and tram lines be built, where could the new cycling expressways run, and where can people switch from their cars to environmentally conscious means of transport? The mobility of tomorrow will be characterised by an optimal interlocking of different forms of mobility - first and foremost an optimised and broadly developed public transport system, a wide network of cycle paths, new offers for commuters in so-called HOV lanes ("High-occupancy vehicle lanes"), dedicated bus lanes and clever mobility concepts in settlement development with innovative means of transport.
Not only population and economic growth pose major challenges for transport infrastructure and settlement development, but at the same time the urban goals for traffic safety ("Vision Zero"), the political and legal requirements for environmental and climate protection (air pollution control, CO2 neutrality) and technological progress (digitalisation and networking) must always be taken into account.
Mayor Dieter Reiter: "Only with a well-developed and, above all, cleverly networked mobility will we be able to master the great challenges. The overall concept published today contains many good ideas for the further expansion of our transport infrastructure. The backbone is, of course, local public transport, which we not only want to greatly expand, but also create further tangential and ring connections in its network. I see this look into the future as a good basis and impulse for further debates. However, the mobility of the future can only be successfully developed in cooperation with the Munich region. In recent years, the city council has passed several groundbreaking resolutions for well-connected, environmentally friendly and space-saving mobility. We want to continue this".
City Planning Councillor Professor Dr. (l) Elisabeth Merk. "In the overall concept, we want to bundle all important measures for sustainable transport planning. It is important to us that we tackle it together. In dialogue with citizens and stakeholders from the region".
Expansion of local public transport (ÖPNV)
Public transport is the backbone of sustainable mobility. To encourage even more people to switch from their cars to public transport, the service will be significantly improved - through the new main station, the second main line, new bus lanes, underground and tram lines, increased frequency, more reliability and comfort. The existing network will be decentralised by tangents and, where sensible, supplemented by innovative means of transport such as cable cars or on-demand services. The result is less congestion and freed-up space that can be used, for example, for lanes for express buses, cycle paths or as amenity spaces.
Improving the cycling infrastructure
Cycling in the city is becoming much safer and more attractive. The continuous and safe "Altstadt-Radlring" (Old Town Cycle Ring) demanded by the citizens' petition is being implemented step by step; every quarter, the city council also decides on a bundle of further measures to make the road network significantly more cycle-friendly. This means that the demands of the second citizens' petition "Radentscheid" will be largely realised by 2025. Munich's first cycle path from the Stachus in the direction of Garching and Unterschleißheim as well as five further star-shaped routes will connect the city centre with the surrounding area; a cycle ring connects several city districts.
New offers for the city-countryside commuter traffic
Work-related commuting between the city and the region is made easier: modern Park & Ride facilities are being built on the motorways and main access roads at the gates of the city. From there, express buses continue on to the city centre on separate lanes without traffic jams and loss of time. The occupancy rate of commuting cars is increased by allowing the bus lanes to be shared by vehicles with several occupants. These "high-occupancy vehicle lanes" are already successfully helping to reduce car traffic abroad. For the "first" and "last mile" to and from public transport stops, more sharing and on-demand services will be provided, for example call buses.
Car-reduced city centre
New parking regulations, fewer parking spaces, traffic-calmed zones and sustainable logistics concepts will reduce car traffic in the old town and city centre. The space thus freed up will benefit cycling, walking and public transport as well as the quality of stay and the green and open spaces that are so important for the urban climate. Necessary, unavoidable car journeys into the city centre will still be possible. However, it is primarily emission-free, innovative means of transport that will shape mobility here. Efficient city logistics concepts make delivery and loading traffic compatible.
Mobility concepts
When planning new neighbourhoods and urban renewal projects, mobility concepts are considered from the very beginning. The focus is on a lively, balanced structure of uses in which as many everyday needs as possible can be found in the immediate residential environment. Short distances, good internal and external access to the neighbourhood by public transport, car and bike sharing services enable people to live without their own cars and increase the quality of life.
Innovative means of transport
Mobility is strongly influenced by digitalisation and innovations. The City of Munich takes these up, plans ahead and is open to trends. Automated and connected driving is currently being researched together with partners from business, science and research; a cable car over the Frankfurter Ring is being studied for the north of Munich, which has heavy traffic. With all new technologies, the focus is on user needs.
On Wednesday, 12 February, the City Council will deal with other important resolutions on mobility in Munich in the Committee for Urban Planning and Building Regulations in addition to the draft resolution "Mobility Plan for Munich".
Difu study provides recommendations for more effective use of funding in NRW
Staff shortages and high administrative demands are two of the reasons that prevent cities, districts and municipalities in North Rhine-Westphalia (NRW) from drawing down available urban development funding on time. This is an important finding of a study conducted by the German Institute of Urban Affairs (Difu) on behalf of the then Ministry of Building, Housing, Urban Development and Transport of North Rhine-Westphalia (now: Ministry of Home Affairs, Local Government, Building and Equality).
In the past ten years, about 83 percent of the municipalities in NRW used urban development funds. Due to a very high number of project applications - with a total volume of around 1.45 billion euros - four to five times more funds were applied for than were originally earmarked. This illustrates the high demand of the municipalities and at the same time the fundamental acceptance of the existing funding instruments.
However, more than 80 per cent of the cities and municipalities surveyed criticise the public procurement law, as the resulting administrative burden is a key obstacle for them in making smooth use of urban development funding. In addition, the municipalities surveyed believe that there are generally major staffing bottlenecks. Many municipalities also feel that the cost calculations for funding measures that have to be submitted with the application are too time-consuming and detailed. This is also due to the fact that multi-year forecasts are always subject to uncertainties regarding the actual time allocation by the funding agencies, price developments and possible unforeseeable developments.
Based on the results of its survey of North Rhine-Westphalian municipalities, Difu therefore recommends dispensing with new programmes in favour of merging and/or redesigning the existing federal-state programmes for urban development funding. In addition, the existing procedures should be made more flexible. This applies in particular to the application for and settlement of funding by the municipalities with the state. However, the municipalities must also make their contribution: urban development funding must be a "matter for the boss" and requires sufficient personnel resources and continuous cooperation between all the departments and treasuries involved in the cities and municipalities. However, the municipalities need support from the state to build up sufficient personnel capacities in the technical areas.
