Sustainable water use: Greater efficiency in the water industry

Health, nature, urbanization, industry, energy, food, and equality are the seven themes being highlighted by the United Nations for World Water Day 2015. Due to deficient or poorly developed infrastructures, adequate access to clean water is not available in all countries around the world. The consequences can be grave and even lead to serious conflicts and crises. And especially in the booming regions of the world, industry needs to be asking where water will come from in the future, and how th ...

The SGT5-8000H gas turbine developed by Siemens is the heart of the highly efficient combined cycle gas turbine power plant

Record-Breaking Power Plant

One of the challenges of Germany’s energy transition is to safeguard security of supply with the rising share of volatile renewable energy feeding into the grid. Stadtwerke Düsseldorf decided to ensure their city’s electricity demand locally, within sight of the city center, with a record-breaking combined heat and power plant at the city’s Rhine port in Lausward – a tailor-made turnkey solution from Siemens. A multimedia TechStory showcases the challenges and achievements, as well as the people ...

the efficiency of the overall system is the key to further lowering the levelized cost of energy from wind

Sustainable energy – efficiency is crucial

Only six more weeks to go until this year’s Hannover Messe, and our preparations for this important event are, of course, running full speed ahead. The motto of the Siemens booth this year is “On the way to Industrie 4.0 – Driving the Digital Enterprise.” But what kinds of highlights and surprises can visitors to the trade show expect to find? In a Hannover Messe blog series our colleague Adam Wesoly offers a preview of what’s to come over the next few weeks.For me, the development of wind power ...

“Today it’s cool to become and engineer, it has completely changed since I was a student,” Prof Jacob Østergaard remembers

A new brand of engineers

This is the final part of our decentralized energy blogpost-series with Professor Jacob Østergaard. Here you can find the first part of the series: The island in building 329 Click here to read part 2: The energy partisan “Follow me, follow me,” the older students carrying the colored flags shout to the dozens of novices following them through the halls of Denmark's Technical University (DTU), set on the fringes of the capital, Copenhague. It is orientation day, and hundreds of students pass ...

Siemens GIL in Kaprun, Austria – 45° installation to connect the Limberg hydro power plant to the grid

Overhead lines in a can – the GIL alternative to power cables

This is part 2 from my gas-insulated transmission lines blogpost-series. Here you can find the introducing part: "Power trip – Are there alternatives to overhead transmission lines?". The increasing demand for power brings high-voltage and extra high-voltage lines closer to the end users in urban areas or even the heart of cities. But space for high-voltage transmission systems is more and more restricted and environmental requirements such as EMC and fire protection are of fundamenta ...

I am a partisan, but don't call the police! - Professor Jacob Østergaard sees himself at the forefront of decentralized energy production

The energy partisan

Professor Jacob Østergaard, electrical engineer and founding head of the Centre for Electric Power and Energy at Denmark's Technical University (DTU), is a respectable scientist. It might strike one as a surprise then if he introduces himself as a partisan. “But please don't call the police,” he says to the team of Living Energy. “I’m a legal partisan, and I’m not using bombs or bullets for my revolution.” Instead, Jacob Østergaard uses steel, polymers, and the latest feats of engineering. “I’m ...

Instead of flying to Bornholm, Professor Jacob Østergaard (right) can steer the EcoGrid EU project remotely from his base at Danish Technical University, DTU

The island in building 329

It's a cloudy day in the outskirts of the Danish capital Copenhague, and the yellow-brick building the team of Living Energy is about to visit looks just like so many others at Danish Technical University (DTU). But once inside, that impression changes quickly. Behind a crowded workshop lies a modern control room, checking the energy supply of an entire island, as Professor Jacob Østergaard points out.The biggest experiment One in ten inhabitants of the Danish island of Bornholm is partaking in ...

Fascinating – Linkin Park live

Power the World: Sustainability and energy poverty are humanitarian issues

Interview with Linkin Park bassist David Farrell Siemens is supporting Power the World, a program launched by the U.S. rock band Linkin Park to support the United Nations initiative »Sustainable Energy for All«. This initiative aims at enabling universal energy access with a strong focus on renewable energy, distributed generation, and energy efficiency. The »Power Booth«, a specially equipped multimedia container from Siemens, Linkin Park, and Warner Music, is calling attention to Power the Wor ...

A vastly increased production of Li-ion batteries, in combination with the integration of intermittent renewable energy, is expected to foster this form of power storage

Batteries: The Storage Form with the Greatest Potential

Batteries beat other storage types in many respects. Their cost is expected to fall rapidly due to the rising popularity of electric cars.Rechargeable batteries and especially lithium-ion batteries have the greatest potential among the storage technologies, experts estimate. There are several reasons for this assessment. Batteries can be activated within seconds and are capable of storing electricity for several hours, making them very dynamic. Their charge/discharge capability is high. Yet anot ...

The variety of potential applications for energy storage is almost as diverse as the range of technical solutions

Electricity Storage: A Puzzling Picture

Electricity storage is a truly complex topic in theory. But the complexity can be reduced for decision-makers if they are presented with the right choice for a particular application.When investigating options for electricity storage, the most striking impression is the complexity of this topic. Both the sheer number and the broad variety of storage types are puzzling and almost overwhelming. The options come in very different forms: mechanical, electrical, chemical, electrochemical, and thermal ...
