Chaussée de Charleroi 146-148/20ETN regularly publishes R&D reports and other publications as part of the activities within our Working Groups. You can download below our reports covering topics such as micro gas turbines, digitalisation, additive manufacturing, hydrogen and supercritical CO2.
ETN Global Laser Powder Bed Fusion (LPBF) Machine Evaluation Initiative assessed the capabilities of LPBF machines from multiple manufacturers, focusing on Alloy 718—a key material for gas turbine components. The study was undertaken by selected members of our Additive Manufacturing Working Group.
ETN R&D Recommendation Report-2023 Edition. The purpose is to provide up-to-date insights and recommendations for R&D topics aligned with user community needs, energy policy targets, and the transformative potential of gas-turbine solutions.
This report was prepared by ETN’s Project Board.
The summary report “Addressing the combustion challenges of hydrogen addition to natural gas” led by ETN’s Combustion task force within Hydrogen Working Group sums up the findings and conclusions as well as presents recommendations from a larger study, which aims to facilitate the introduction of gas turbines firing the full range of hydrogen and natural gas blends to deliver heat & power.
This report, prepared by ETN’s Gas Turbines Life Assessment and Extension Working Group, outlines the current status and future potential of extending the service life of gas turbine rotors. Initiated by ETN gas turbine users, it addresses the need for asset extension in the technical landscape. The report delves into rotor life definition, degradation mechanisms, OEM recommendations, and the necessity of extending fleet lifetimes to meet energy demands. It also discusses the lifetime assessment process and draws parallels with flight engine procedures to propose an action plan for improving rotor life extension practices.
ETN Global Hydrogen Gas Turbines report 2024 version was issued as part of the activities of our Hydrogen & alternatives fuels Working Group.
ETN Global 2024 HLUM report offers a comprehensive analysis of the challenges and opportunities facing the gas turbine users. Based on insights from pre-meeting interviews with stakeholders across all sectors and in-depth discussions during the meeting, the report provides a detailed examination of the technical, market, and regulatory challenges faced by operators. It outlines the path forward as the industry works towards current low-emission targets and ambitious net-zero goals.
The techno economic case study “Hydrogen Deployment in centralised power generation” was led by ETN’s Young Engineers Committee. It is an evaluation of the technical feasibility and economics of hydrogen utilisation for large-scale, centralised power generation.
The full report “Addressing the combustion challenges of hydrogen addition to natural gas” was written by ETN’s Hydrogen combustion task force. It presents the findings, conclusions and recommendation, aiming to facilitate the introduction of gas turbines firing the full range of hydrogen and natural gas blends to deliver heat and power.

ETN’s position paper titled “Proposed NOx emissions reporting for hydrogen-containing fuels”. The background for this paper is the current normalisation method that is being used for correcting emissions, in particular nitrogen oxides, to reference conditions, which adds a burden of up to 40% on hydrogen compared to natural gas.
The report “Decentralised energy systems: Towards carbon-neutral energy solutions for gas turbines” is part of the activities undertaken by ETN Global’s Decentralised Energy Systems Working Group. The report delves into the critical role of Decentralised Energy Systems (DES) in achieving carbon-neutral energy solutions, particularly focusing on the integration and application of gas turbine technologies. This comprehensive report outlines the current state of DES, highlights market trends, and identifies technological challenges and opportunities.
The ETN report“Best practices for defects detection in additively manufactured components in the energy sector” gives a general overview of the current utilisation, development and future trends of additive manufacturing (AM) in the energy sector, highlighting the actual knowledge of the defects induced by AM processing. This publication is available for ETN members only (login required).
ETN’s “Business case for sCO2 Waste Heat Recovery System” report was published in October 2020 as part of the activities within ETN’s sCO2 Working Group.
The objective of ETN’s White Paper “Industrial Internet: the next age of productivity for European GT based plants” is to provide support and guidance to the ETN members on Industry 4.0 and the Industrial Internet. The content was developed during ETN Workshops in 2016-2017, in a joint effort between Technical Committees 4 and 5, and the full paper was presented at ETN’s IGTC in October 2018.
The Micro Gas Turbine Technology Summary was produced by ETN’s Micro Gas Turbine Working Group composed of MGT OEMs, heat exchanger manufacturers and R&D institutes. This document aims to identify a number of key areas that require substantial R&D efforts for micro gas turbines from the European community to become competitive in the energy sector worldwide.
ETN R&D Recommendation report – 2021 Edition. This report was prepared by the ETN Project Board, which provides an independent support to new initiatives or issues brought to the ETN platform. The report includes recommendations on key research topics of gas turbine development based on the current market outlook and the users’ requirements.
The ETN Hydrogen Gas Turbines report 2020 version was issued by ETN, as part of the activities of our Hydrogen Working Group.
