The Dutch government has awarded subsidy to six partners including Ansaldo Thomassen, Delft University of Technology, OPRA Turbines, Vattenfall, Nouryon and EMMTEC for the project ‘High Hydrogen Gas Turbine Retrofit to Eliminate Carbon Emissions’
The subsidy, valued at US$565.58,000, is awarded as part of the Dutch hydrogen programme within the top sector energy area of the Dutch Ministry of Economic Affairs and Climate Policy.
This amount is apportioned among all partners of the consortium based on their specific contributions to the project. The subsidy was approved considering the cooperation of partners from Dutch academia and industry.
The Dutch hydrogen programme focuses on future carbon-free hydrogen value chains in line with European Commission 2050 Energy Strategy Directives.
As hydrogen can deliver a carbon-free solution for industry, mobility, housing and the power sector, the programme aims to enable joint innovation between Dutch companies and institutes to be able to deliver economic value in the short-to-medium-term.
The major objective of the project is to develop cost-effective ultra-low emissions (sub-9ppm NOx and CO) combustion system retrofit for existing installed gas turbines in the output range of one megawatt to 300MW.
Fuel flexibility and stable operation from 100 per cent natural gas to 100 per cent hydrogen and any mixture is a major requirement. This is a major challenge as extreme changes in fuel reactivity switching from natural gas to hydrogen can result in dramatic shifting of heat release within the combustor, which can be physically destructive if not well controlled.
At the centre of this innovative high-technology project is the patented and novel aerodynamic trapped vortex FlameSheet combustion technology platform, owned by Genoa Italy-based Ansaldo Energia. The FlameSheet combustion system is operating commercially in multiple 60hz F-Class gas turbine power plants with sub-9ppm NOx emissions including with the use of hydrogen- blended fuel mix.
The prime focus of this award from the Dutch government is a full-scale atmospheric verification in 2020, which will ultimately lead to a first engine demonstrator by 2023.
The lead applicant, Ansaldo Thomassen BV is an experienced expert in high technology gas turbine retrofits. Delft University of Technology provides advanced theoretical, computational and experimental experience in support of advanced high hydrogen combustion development. OPRA is a manufacturer of gas turbines with access to state-of-the-art test facilities which will play an important role in the project. The knowledge from this project will enable the power plant operator partners Vattenfall, EMMTEC and Nouryon, to make significant progress in the realization of dry low NOx, carbon-free production of power and heat. Hydrogen generated from renewable energy resources such as excess wind and solar will also allow existing gas turbine power plants to become part of the large-scale energy storage solution.
