BEST - WP4: ENERGY RESTITUTIONTASK 4.1. DECENTRALIZED RESTITUTION
Ward De Paepe
Kick-off Meeting
February 13th, 2020
Main question addressed in this WP
How can we efficiently use electrofuels to retrieve the stored
energy?
In BEST, two main routes are considered
Electricity production
Mobility Applications
WP4.3: Prof. Verhelst
Shift from centralized to decentralized,in the form of combined heat and power production.
WP4.2: Prof. Blondeau
Shift from centralized to decentralized,in the form of combined heat and power production.
WP4.1
Focus on two key technologies for decentralized combined heat and power
Piston Engines micro Gas Turbines
To get a place in the future energy production,the mGT and Piston Engines need to evolve
They need to become more efficientboth at full and part load operation
They need to become fully CO2 neutral/negative
by using E-fuels (H2/NH3)by integrating CCUS
They need to become MORE flexibleflexible in terms of fuel and operation
è In BEST, focus on fuel flexibility
Development of Homogeneous Charge Compression Ignition (HCCI) in Piston Engine
Homogeneous Charge Compression Ignition (HCCI) offers theoretically
high fuel flexibilityhigh efficiency (>50%)for small-size (1-10MW)
Potential still needs to be demonstrated in real conditions
è at UCLouvain, a lab-scale engine will be placed in realistic conditions
Development of Homogeneous Charge Compression Ignition (HCCI) in Piston Engine
Assessment of concept of a multi-fuel, high-efficiency, low-NOx emissions mGT for residential use
mGT offers high potential for local restitution
humidification for operation flexibilityEGR reduces Carbon Capture costproven to work with H2 and NH3
Main challenge remains fuel flexibility, which requires novel combustion mode.
è Development and tests of Flameless Combustor in actual mGT (ULB+UMONS)
