About Us

Dolphin N2
  • Innovate project “StepCo2″consortium of UK manufacturers and universities was formed in 2017 and led by Ricardo PLC to develop the split cycle technology and to produce a demonstration engine.
  • Dolphin-N2 was created internally in Ricardo as a separate group
  • Dolphin N2 is purchased by FPT Industrial in December 2019 and takes the lead in StepCo2 project.
  • Dolphin N2 develops the technology for first scale demonstration in 2020, and forms a further APC grant funded consortium to showcase hydrogen capability.
Dolphin is developing three variants of split cycle technology:

  • CryoPower®; which includes liquid Nitrogen injection in the compressor
  • ThermoPower®; which includes Water injection in the compressor
  • ThermoPower® will be the first technology to be introduced for road transport and power generation.
  • June 2021: Engine running on hydrogen
  • December 2020: first full-scale demonstration
  • August 2020: Awarded APC ARMD grant
  • December 2019: acquired by FPT Industrial
  • January 2018: Proof of concept for combustion system using single cylinder engine at University of Brighton

Dolphin N2 was created by Ricardo PLC to continue the development of the Split cycle engine. The name “Dolphin” is taken from the first engine developed and produced by Sir Harry Ricardo, the popularity of which laid the foundations of Ricardo PLC.

In December 2019 Fiat Powertrain limited purchased Dolphin N2 to support the development.

The split cycle engine has the potential to reduce fossil fuel use by up to 30% whilst simultaneously reducing air pollutants to below any future planned legislation.

The concept is covered by 8 international patents and a single cylinder proof of concept engine has been running in Brighton University on an Innovate UK programme to reduce carbon emissions from heavy transport.

Mario Borromeo

Purchasing & Stores Support, Dolphin N2

Having worked within the engineering industry over the last 30+ years, Mario has extensive experience in a wide range of roles, including Production Management and Supply Chain Management.

In Mario's previous employment the company manufactured precision-machined components for the Medical, Aerospace and Oil & Gas Industries. My main responsibilities were to manage a team to strategically procure all items, to facilitate the engineering of these specialised components. This would include the requirement to subcontract processes (including material) where required, to ensure the timeliest and cost-effective outcome.

Something that motivates Mario is the chance to build positive and prosperous working relationships with my colleagues and suppliers alike.

The opportunity to explore a new challenge with Dolphin-N2 provides a new, exciting motivation.
