ETN Webinar on “Finno Exergy’s PGC Technology: a novel solution for efficiency improvement and fuel flexibility in gas turbines”

December 2023

ETN Global is glad to invite you at its new webinar entitled Finno Exergy’s PGC Technology: A Novel Solution for Efficiency Improvement and Fuel Flexibility in Gas Turbines.  The event will take place on Friday, 15 December from 10.00 to 11.00 (CET).


The virtual event is jointly organized with ETN MemberFinno Exergy. Since 2015, Finno Exergy has been developing a novel pressure gain combustion system for gas turbines applications. The technology has the potential to reduce fuel consumption and enable the retrofitted gas turbine to operate with any mixture of hydrogen and methane.  In this webinar, Fabio Ciccateri (Chief Technology Officer, Finno Exergy) will describe Finno Exergy’s technology basic principles, the potential reduction in fuel consumption and CO2 emissions, the technology development up to date and next steps towards a commercial implementation of the combustion system.


Registrations & attendance

Registrations to this event are free, but mandatory. To register, please follow the link here. We are looking forward to seeing you online!

Positive publicity in the Tekniikka & Talous-magazine

November 2023

Finno Exergy has received positive publicity in the Tekniikka & Talous-magazine. The excellent results of the combustion chamber tests have been noted in a Finnish technology magazine. We continue to scale the technology to the commercial version and have started selling to gas turbine manufacturers to deliver the first PGC combustion chambers in the next few years. Our cooperation with Shell continues and we have signed a joint Memorandum of Understanding to continue our journey in reducing CO2 emissions.

Finno Exergy advancing its innovative gas turbines technology with the help of Shell GameChanger

September 2023

Company aims to help decarbonize hard-to-abate sectors and contribute to development of hydrogen economy by making technology available to the global market.

Finnish company Finno Energy is aiming to take another step forward in commercializing its gas turbines technology after proving its functionality through a successful testing phase which concluded this spring.


With the help of Shell Gamechanger, Finno Exergy's team has validated their proof of concept and will now advance its research & development work toward commercial utilization.

"Finno Exergy has developed a solution that has shown potential to cut gas turbines’ CO2 emissions by up to 20%. In addition, our pressure gain combustion system works with any mixture of natural gas and hydrogen. This feature has potential to enable the direct utilization of hydrogen in the sectors where emissions are hard to abate, like heat and power generation in industrial applications, and dispatchable electricity generation.

For end users, like a manufacturing plant, our solution could deliver substantial cost savings and emissions reduction by improving the efficiency of energy production," says Mr. Timo Erämaa, Founder and CEO of Finno Exergy.

The essence of the innovation is a more efficient combustion system for gas turbines applications. Gas turbines are widely applied across many sectors and industries.

As the innovation is fuel-agnostic, meaning it can use any type of fuel, including hydrogen, it has potential to accelerate the transition to lower-carbon options like lower carbon hydrogen.

"We have been developing and piloting our solution in cooperation with Shell GameChanger since we won the New Energy Challenge competition in 2020 and our unique innovation is now protected by 10 patent families in Europe, the United States, China and Japan, ” says Mr. Fabio Ciccateri, Chief Technology Officer at Finno Exergy.

Finno Exergy's goal is to start the first customer projects at the end of 2023 and to achieve a turnover of more than EUR 130 million through license sales in 2027. Commercial negotiations with potential customers, including gas turbine manufacturers worldwide, are already underway. Finno Exergy is starting a new project, in collaboration with academic and industrial partners, focused on the design and test of a retrofitting package for a selected industrial gas turbine, to be used as a technology demonstrator. Shell GameChanger will continue to monitor Finno Exergy’s technology development for awareness about the progression and maturation of this technology.

We have started testing and validiation in Helsinki with our new test rig



Our test rig is operating at our test lab in Helsinki. We managed to burn hydrogen and methane separately and together. More test results will be published in December.


We have recruited senior designer James, senior test engineer Osmo and junior test engineer Jenni to our team together with gas specialist Kari and test engineer Pertti. We also start scientific project at Florence University by Clarissa.


Our seed round is ongoing and if you are interested to join in, please contact our CEO Timo.

Finno Exergy has completed the phase 1 of the "Shell GameChanger" program



The project started after the victory of the "New Energy Challenge 2020" and ended in October 2021. During these months we installed on our prototype an additional power turbine and new measurement equipment. This upgrade enabled us to calculate the thermal efficiency of the system and to compare it with an equivalent ideal traditional gas turbine.

The experimental results showed the potential of efficiency improvement of up to 40% for small gas turbines applications, in line with our forecast.

We are starting next phase technology and research project at the Energy transition Campus Amsterdam from 1st of September.

Finno Energy has made various new simulations


Finno Energy has made various new simulations of its process in different sizes and gas turbine applications. The results are excellent, and they are proving the flexibility of Finno Energy PGC technology.

Finno Energy started a project with a major gas turbine manufacturer

November 2018

The goal of the project is to show the potential of Finno Energy’s pressure gain combustion applied to their technology.

First coupled simulation with GT-POWER and CONVERGE CFD was run on Finno Energy’s digital development platform


The simulated pressure trace matched the pressure trace that was measured from the test unit. Simulations with the new design are giving promising results about the technology’s potential.

The testing of the updated test unit has shown some really promising results


New record in pressure gain was measured with the new setup.

Finno Energy updated their digital development


Finno Energy updated their digital development platform with an in-house High-Performance Computing (HPC) facilities. The facilities are used to run CONVERGE CFD simulations of our process. The new HPC cluster consists of 144 cores.

Finno Energy did a major update to the test unit

December 2017

The updated test unit is now ready to be tested. The team is waiting for excellent results from the tests.
