Energy storage – the Holy Grail of renewable energy


Isentropic Ltd is at the forefront of an exciting, new £100 billion industry sector – energy storage for renewables. We believe our Pumped Heat Electricity Storage (PHES) technology is the only viable, long-term solution for large-scale electrical energy storage and recovery.

We are a privately funded UK engineering start-up where creativity is actively encouraged and facilitated by a management team led by engineers. Based near Fareham in Hampshire, we are building an in-house technical team of up to 30 people to take our PHES technology from design and development to market.

We are looking for people from a diversity of backgrounds, including physics, mechanical engineering, fluid dynamics, aerospace engineering, engine design, thermodynamics, heat transfer, materials science, and electrical power machinery. The ideal candidates will be creative, innovative, hands-on engineers with highly developed analytical skills.

We would like to hear from you if you have expertise in one or more of the following areas:

  • design experience in engine or powertrain design
  • experience of machinery and systems operating at high (>500 deg C) or low temperatures (-160 deg C or below)
  • experience with electrical power systems ranging from 100 kilowatts to multi-megawatt
  • modelling of complex systems and matching of results to experiment
  • designing complex machines and systems from first principles and
  • are passionate about engineering and solving problems

We offer competitive salaries and benefits and, because we want everyone at Isentropic Ltd to share in the company’s success, a share option scheme for all team members.


We are now recruiting for the following newly created roles:
