The future is uncertain for IPG Energy – a regular star of our EnviroTech 50 ranking – after a technical blow halted its ability to commercialise its tech.
The London firm has developed Flameless Combustion technology – backed by academic institutions, government agencies and pioneering manufacturing and commercial partners – which delivers pollutant-free power from any fuel.
However CEO Toby Gill, who joined as a business development analyst in 2017 and moved through the ranks to become CEO in 2020, wrote on its website that in recent testing, it encountered an “unforeseen engineering challenge” which “limits overall system performance and means the unit is not yet ready for deployment with pilot customers”.
“In light of this, the board has taken the decision to scale back the focus of the business. We will no longer be pursuing the commercialisation of our generator product and will instead concentrate on the underlying Flameless Combustion technology.
“As part of this transition, the company will no longer maintain an operational team and will focus on how the technology can be taken forward through third parties.”
