Cost-efficiently modernising heating networks


In the last thirty years, the population of Duisburg has declined by more than one-fifth with a simultaneous reduction in the heating requirement. On behalf of the municipal utility company, an engineering company has investigated how the heat supply can be adapted to this development. The BINE-Projektinfo brochure “Future heating supply designed” (16/2015) describes possible scenarios.

Experts design scenarios for Duisburg’s heating supply

Based on the characteristic values for 2011, the experts investigated how the network structures could be optimally designed in future and whether a change of energy sources would be useful. They simulated the possible heating supply for the years 2020, 2025, 2030 and 2050.

Above all, connecting the Central/West/South district heating network with the adjacent district heating system proved to be a sensible solution. This would improve the utilisation of industrial waste heat and the primary energy efficiency would increase. The connection between the two networks is currently being checked as part of a planning approval procedure.

In many areas of Duisburg there is a parallel distribution of heat and gas. This is not always sensible and the engineers investigated in which areas the customers should be primarily supplied with gas or district heating. They also defined areas where a parallel supply continues to be appropriate.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
