A New Paradigm in EV Charging - More Convenient, Less Expensive

I had the pleasure this week at LinkedIn’s global headquarters of helping to introduce a radical new concept in electric vehicle charging.FreeWire Technologies, Inc. is piloting its invention, the Mobi Charger™, to provide EV charging to LinkedIn’s employees. Mobi Charger turns traditional charging on its head by bringing the charger to the car – instead of the driver bringing the car to the charger. Siemens is a partner in the project, providing the data collection, management, and energy billi ...

What is biogas, what are some approaches to digester optimization and how does it affect me?

If you work in or around the wastewater industry you have most likely heard of, or been involved in some sort of investigation on solids waste digesters. Their use in the industry has surpassed just being a trend and is getting closer to becoming an ubiquitous facet of most medium-sized to large-sized facilities.I recently attended a 2-day conference on wastewater with my sole objective being to understand the general attitude toward the operation of digesters, what facilities are doing to optim ...

Transformers, backbones of the AC Voltage Grid

At the early age of electricity a war of currents took place— DC v.s. AC, also known as direct current and alternating current. Both technologies offered many advantages but also disadvantages. One major step towards today’s alternating current grids was the invention of transformers. The transformer enabled higher voltage levels in the grid, which allowed a more efficient transmission of energy and application specific voltage levels. That was the beginning of the success story of transformers. ...

Weinhold’s Power Lines: Brains and Brawn - The Electronics Revolution and the Energy System

What is power? In human interactions, the term often refers to physical strength, but we also speak of “the power of information” as a way of shaping and directing the course of events. Power is the ability to influence the world in both material and immaterial ways – through intelligence and muscles, through brains and brawn. The same is true for the way in which electronics has reshaped the energy system. It was the invention of the transistor and its first commercial usage in the 1950s that ...

Tesla, cheaper batteries for solar systems, and managing the demise of traditional utility business models

A few weeks ago, Tesla Chief Executive Elon Musk took to Twitter to issue a new product announcement tease: “Major new Tesla product line—not a car—will be unveiled at our Hawthorne Design Studio on Thursday at 8 pm, April 30.” Word on the street is that the new product will be Tesla’s entry into home energy storage, leveraging Tesla’s battery Gigafactory announced last year. This joint venture between Tesla and Panasonic, expected to be completed in Nevada in 2020, would become the world’s larg ...

SIESTORAGE - initial installation at Enel in Italy

Continuous Power Flow? Totally Integrated!

Walking from one end of Siemens’ 3,500-sqm exhibition area to the other at this year’s Hannover Messe one solution was prevalent across all areas, from Energy to Industry: Totally Integrated Power. It was a way to physically experience the comprehensive scope of Siemens’ end-to-end portfolio encompassing software and hardware products, systems and solutions for all voltage levels – from high-voltage in-feed, to low-voltage consumption, from grid access via industry application to home supply. Ba ...

Le parc éolien Tarfaya (Maroc) exploite le vent

42 % d'énergie renouvelable d'ici 2020 : pour atteindre cet objectif, les pouvoirs publics marocains font appel à Siemens depuis des années. C'est ainsi que fin 2014, le parc éolien de Tarfaya a été mis en service. Il s'agit du plus grand parc onshore d'Afrique : 131 turbines SWT-2.3-101 produites et installées par Siemens fournissent chacune 2,3 MW d’énergie.

How Digitization Drives Smart Grid Innovation

At this year’s Hannover Messe Siemens is showcasing the opportunities of Industry 4.0 and digitization for the energy business. The first blog post in the Hannover Messe series explained how necessary gains along the wind energy value chain can only be achieved with intelligent, digital solutions – ranging from software for blade optimization via control systems for wind power plants to machine learning solutions for wind turbine self optimization. Next, I would like to introduce a further promi ...

underground ac transmission lines in Germany, direct buried

Lines in a Can yet again – this Time for Direct Current

DC CTL and HVDC might sound like alphabet soup, but actually they are technologies to transmit electricity over long distances. Brunsbüttel to Stuttgart – nearly 700 kilometers. Güstrow to Munich – almost 900. In future, ever more electrical power will need to make such journeys, from offshore wind farms in the Helgoland Bight to population centers in the depths of Germany. This will be critical to the Federal Republic’s aim of generating 80% of its power by 2050 from renewable energy. It also ...
