When Tokamak Energy was established by company founders Dr Mikhail Gryaznevich, Dr Alan Sykes and Dr David Kingham, we embarked on a unique mission: to recreate the process that powers the sun – on earth.

Mimicking the sun here on earth is an enormous scientific and engineering challenge. The temperatures needed for efficient fusion to occur are over 100 million degrees and confining and controlling the immensely hot, sometimes unstable plasma, is a complicated task.

Very sophisticated systems are required to manipulate the plasma and after decades of research tokamaks can nearly produce and sustain the plasma conditions needed for efficient fusion to occur.


2009

  • Tokamak Energy Ltd founded

    Tokamak Energy is established by Dr Mikhail Gryaznevich, Dr Alan Sykes and Dr David Kingham. The company, a spin out of Culham Laboratory, aims to design and build compact spherical tokamaks to use as neutron sources for a range of scientific applications.

  • Gideon Hammond becomes the company’s first employee. ‘Gid’ remains an integral part of the Tokamak Energy team today.

2012

  • The company focus and strategy changes to find a faster way to fusion power.

  • Clock

    Plasma pulse:3 Milliseconds

    ST25

    The ST25 working prototype compact spherical tokamak is built and successfully tested at Culham. The device achieves plasma for three milliseconds. This demonstrates that Tokamak Energy can rapidly build and test working prototypes.

  • Patent

    Tokamak Energy files its first patent application on fusion power from a compact spherical tokamak with HTS magnets.

2013

  • Clock

    Plasma pulse:5 Seconds

    ST25 Upgrade

    Testing begins on the ST25 Upgrade that features high temperature superconductors. The increased pressure and temperature afforded by HTS magnets achieves a plasma pulse for five seconds

  • Patent

    Tokamak Energy files another patent on fusion power from a low power spherical tokamak.

2014

  • Clock

    Plasma pulse:100 Seconds

    ST25 HTS

    The ST25 HTS device is built, featuring all high temperature superconductor magnets. First phase testing is successful with plasma pulse lengths extended to over 100 seconds.

  • Paper

    Papers published showing tokamaks do not have to be huge to be powerful.

2015

  • Patent

    Our UK patent on ‘HTS magnets for use in spherical tokamaks’ is granted in the UK.

  • Clock

    Plasma pulse:29 Hours

    Second phase testing of the ST25 HTS demonstrates the enormous potential of Tokamak Energy’s compact spherical tokamak device. During the Royal Society Summer Exhibition, the device achieves continuous plasma for 29 hours – a new world record.

  • Patent

    Setting a new world record allows Tokamak Energy to file four new patent applications on HTS magnets.

2016

  • Patent

    Further patent applications on HTS magnets are filed. Paper on the physics, engineering and financial viability of compact fusion is also submitted for publication.

  • ST40

    Tokamak Energy designs and starts to build its ST40 device, the world’s first high field compact spherical tokamak. The device has a diameter of two metres.

2017

  • Patent

    First patent is granted in Japan

  • First plasma in ST40
  • Patent

    First patents granted in Europe

  • Patent

    A total of 18 families of patent applications have now been filed by Tokamak Energy.

  • HTS MAGNET
