  • Hon banar väg för elbilar

    Published Apr 23, 2013

    Elbilarnas miljöförtjänst beror på förarnas beteende när de laddar sina elbilar. Det slår KTH-forskaren Pia Grahn fast. Hon har gjort en kartläggning som beskriver när elbilsägare laddar sina bilar.

  • Hon laddar för framtiden

    Hur väl elbilar med uppladdningsbara batterier kommer bidra till en mer hållbar miljö beror delvis på förarnas laddningsbeteende. I sin licentiatavhandling har Pia Grahn kartlagt elbilisternas laddningsmönster. Det kan motverka konsumtionstoppar i elnätet när fler elbilar ska in i systemet.

  • KTH-forskare: Elnätet är väldigt sårbart

    Published Dec 12, 2012

    Den sjätte november drabbades Stockholm av ett elavbrott. Stora delar av tunnelbanan, pendeltågen och SJ-tågen slogs ut. Det första elavbrottet i sig varade inte så länge, men effekterna av det dröjde sig kvar desto längre. Detta i form av så väl nya elavbrott ända upp i Gävle som kraftiga förseningar i lokaltrafiken.

  • Induction machine generating reactive energy

    Published Sep 18, 2012

    What if it was possible to generate reactive power from the rotor of the induction machine in remote areas where there was no grid available? Naveed‐ur‐Rehman Malik and his colleagues have developed the first induction machine that theoretically holds to the test.

  • New method opens for more renewable energy

    Published Sep 03, 2012

    A new advanced control method for power converters in electric transmission systems will permit for substantial power loss reductions. Used for HVDC solutions, this new technology will among other things open up for increased penetration of renewable energy sources in the energy system.

  • Electrified roads - TEDxKTH

    Published May 28, 2012

    The world is today facing a grand challenge when it comes to transforming the present energy system, that to large extent is based on fossil energy sources, to a future system that relies on renewable energy sources. This is particularly true for our transports. Regardless how the solution will look like, one thing is certain, electricity will play a major role.

  • New material paves the way to more effective energy

    Published May 22, 2012

    In the future, we can expect to become more dependent on different sources of energy. This will demand smarter electric grids that can handle variations in power generation. At the kth School of Electrical Engineering (kth ee), researchers have developed a new type of power converter that makes the equation possible.

  • The converter that reduces energy losses by a factor of ten

    Published Dec 14, 2011

    Researchers at Electrical Energy Conversion have developed an energy converter with an efficiency close to 100 percent. The converter will, among other things, make our electric cars, hybrid cars, electric trains and cross-border electricity grids more energy and cost efficient.

  • From research to finished product

    With solid expertise and experience, KTH was the obvious partner when Bombardier decided to develop a new drive system for trains, a technology that is already contributing to faster, more efficient and more energy-saving trains.

  • Environment-smart car a winning concept

    Published May 25, 2011

    The car of the future is not just climate-smart. It will be a cog in our entire energy-consuming society. It will be powered by hydrogen and electricity, and instead of just standing idle in the garage when not in use, it will be able to function as an energy source.

  • Brighter times for solar electricity

    Published Oct 12, 2010

    Solar energy is a business area on the move. Major investments are underway in Europe and China. Sweden has the opportunity to contribute the technical expertise necessary to supply Europe with cheap electricity - from the Sahara! Last week the KTH solar cell facility was inaugurated with that goal in its sights.
