Innovation and Service for a World with Clean Power

About us

Ansaldo Thomassen B.V. (ATH) is a leading supplier of technologically advanced aftermarket gas turbine components, performance upgrades, in-house component repair and outage services for existing GE Frame 3, 5, 6B, 7E, 7F, 9F platforms. We offer flexible and comprehensive Service Agreements (FSA’s), ranging from parts supply and reconditioning to full scope agreements including remote monitoring and diagnostics and inventory management. ATH is a proven alternative with parts and upgrades successfully operating for more than 10 million operating hours in over 10 GW of installed gas turbines.

Our Vision

Our vision is to supply cost effective advanced retrofit solutions for a Clean Energy World. ATH is leading a consortium targeting the demonstration of gas turbine retrofit technology for hydrogen. This technology will allow flex operation from 0-100% hydrogen in machines sized from 1MW to 300MW.

The significant growth of renewables (solar and wind) in markets such as Europe have highlighted the tremendous opportunity and need for balancing with fast/flexible/clean electrical generation. Gas turbines offer the ideal solution for grid balancing, and many gas turbines in Europe are restarting to take advantage of the opportunity. By harvesting the excess electricity in peak renewable generation periods through the production of hydrogen, and then releasing this fuel into gas turbines when renewable generation swings to under supply, existing gas turbines can be effectively retrofit to become super batteries. Balancing the electrical grid with carbon free hydrogen fuel is becoming a primary focus for economic stimulus in Europe. ATH is actively involved leading this technology evolution with our retrofits for renewables.
