Descripción del proyecto
Combustión secuencial a presión constante: aumento del uso de hidrógeno en turbinas de gas modernas
Emplear hidrógeno (H2) gaseoso en vez de gas natural u otros combustibles fósiles en las turbinas de gas respaldará la generación de energía eléctrica sin emisiones de dióxido de carbono (CO2). En el proyecto FLEX4H2, financiado con fondos europeos, se desarrollará aún más una tecnología de combustión patentada, conocida como «combustión secuencial a presión constante», que tiene un gran potencial para su funcionamiento limpio y estable utilizando H2 mezclado con gas natural en cualquier concentración, hasta el 100 %. La tecnología se ha implementado en la turbina de gas GT36 de clase H desarrollada por Ansaldo Energia. El equipo del proyecto optimizará la tecnología al combinar métodos informáticos y analíticos con campañas de pruebas experimentales, lo que permitirá demostrar el funcionamiento de la cámara de combustión con concentraciones de H2 del 70 %, 90 % y 100 % en un entorno relevante para motores en laboratorios de categoría mundial.
Objetivo
The project aims at moving technological frontiers for low-emission combustion of hydrogen to fuel modern gas turbines at high firing temperatures and pressures, beyond the latest state-of-the-art. This will be achieved whilst maintaining high engine performance, efficiency, fuel and load flexibility, without diluents. At the same time, all emission targets set by the Clean Hydrogen JU Strategic Research and Innovation Agenda (SRIA) will be met.
The idea is based on a proprietary combustion technology, designated constant pressure sequential combustion (CPSC) already deployed into the GT36 H-class engine (760 MW in combined cycle). The CPSC concept, based on a unique longitudinally staged combustion system, yields the best fuel flexibility and has the greatest potential to achieve the project target of demonstrating stable and clean combustor operation with concentrations of hydrogen admixed with natural gas, up to 100%, at firing temperatures typical of modern H-Class engines. The new, improved combustor design will be fully retrofittable to existing gas turbines, thereby providing opportunities for refurbishing existing assets.
The primary objective is to demonstrate the CPSC technology in engine relevant environment (TRL6) in three steps (70, 90 and 100 vol% H2). In this pursuit, a subset of specific performance data (KPIs) will be met within the project timeline and with the planned resources and allocated budget.
The project uses state-of-the-art computational tools, analytical modelling, and diagnostic techniques to investigate static and dynamic flame stabilisation. Testing is performed at world-class laboratories in test campaigns at reduced scale and in full size (at atmospheric and pressurised conditions).
In preparation for commercialisation, the project will also develop a roadmap towards deployment of the developed system into operation and demonstration into a power plant environment quantifying the valuable contributions to the EU Green Deal.
