System LCOE: applying a whole-energy system model to estimate the integration costs of photovoltaic

On the road to a carbon-neutral continent, Europe will have to implement major changes to its energy system. The following transformations are needed: massive integration of renewable energies, from which intermittent ones; electrification of the heat and mobility sectors; use of renewable fuels (e.g. biogas and hydrogen); and use of storage technologies. As a result, the energy system of tomorrow will be very different from that of today. Recently, technologies based on intermittent renewable announced cheaper production costs than their equivalent fossils. However, these announced costs usually do not account for the adaptation of the energy system to implement back-up technologies or reinforce the grid. The levelised costs of electricity (LCOE), a common metric to compare electricity generation technologies, is extended in this work to compare dispatchable technologies with intermittent ones. By applying an energy model (EnergyScope TD) that optimises the system design and operation, it computes the integration costs of photovoltaic energy and therefore its system LCOE. We find that accounting for the integration costs almost double the system LCOE of the photovoltaic compared to a LCOE calculated on the technology only. Another key finding is the importance of the electrification among sectors, which facilitates the integration of additional intermittent renewables and at a cheaper cost

CFD simulations of the iso-octane ignition in a Rapid Compression Machine using detailed chemistry

The Rapid Compression Machine (RCM) is widely used in the study of auto-ignition phenomena at temperature and pressure conditions similar to those of standard combustion devices such as an internal combustion engine. A reactive and homogeneous mixture is rapidly compressed by a moving piston: the subsequent auto-ignition provides information that help developing detailed chemical kinetics models. The machine-to-machine variability observed in the experimental results is however a key question that needs to be definitely addressed as it is still an active topic of discussion in the RCM community. In this study, CFD simulations first for non reactive investigations, and then coupled to detailed chemistry for the ignition of iso-octane will highlight the strong machine-dependence of RCM experiments.The Rapid Compression Machine (RCM) is widely used in the study of auto-ignition phenomena at temperature and pressure conditions similar to those of standard combustion devices such as an internal combustion engine.
