Within the sCO2Flex project, funded by European Union Program Horizon 2020 (grant agreement #764690), the consortium addresses the necessities to upgrade existing fossil fuel plants to integrate renewable energy sources increasing the overall efficiency in power generation plus avoiding the use of water. Deliverable of the project is the development and validation of all main components of a sCO2 Brayton cycle capable to provide 25MWe at 100% load ensuring a wide plant flexibility (from 100% to 20% of the electrical load). Moreover, a centrifugal compressor prototype has been designed and manufactured to operate in proximity of CO2 critical point, with the aim of maximizing the thermodynamic cycle efficiency. Specific models and equation of state have been implemented to properly predict CO2 behavior close to critical point, even in the event of multi-phase conditions which could occur in low-pressure regions inside the gas path.
Gas turbine system with diffusion-flame combustion and fuel blending for the reduction of undesired emissions
Speaker: Marco Baldini, Strategic DTI Manager Hydrogen Gas Turbines and Systems
In the overall scenario of energy sector decarbonization, one of the promising technology solutions to reduce emissions is burning low-carbon fuels in gas turbines. Hydrogen is the low-carbon fuel whose application is expected to grow most. Burning hydrogen in gas turbines will enable reduced carbon emissions at the exhaust, lowering the carbon footprint of combustion in all energy sectors. Hydrogen combustion produces no carbon emissions, since the hydrogen molecule does not contain carbon atoms. Hydrogen combustion can, however, generate high nitrogen oxide (NOx) emissions.
Energy storage systems adoption to decarboniseelectricity production from power generation islandsservicing large industrial gas processing plants
Speaker: Marco Bruschini, Electrical Integration Leader
Electricity production from fossil energy sources, including power generation islands serving gas processing plants, is one of the main causes of anthropogenic greenhouse gas emissions. In this paper, Baker Hughes expert Marco Bruschini evaluates the impact of a utility scale electrochemical energy storage (BESS) adoption into a power generation island with the joint purpose to supplement the synchronous generation spinning reserve, without one extra Gas Turbine in “N+1” configuration, and to permit partial injection of intermittent renewable source.
