    Contracts for Difference (CfDs) have emerged as a key policy instrument to incentivize renewable energy investments by mitigating revenue volatility. However, conventional CfDs, while effective in fostering growth in renewable energy sources, can introduce market distortions. These distortions arise from misaligned incentives, particularly the ‘produce-and-forget’ mentality, where generators prioritize maximizing production without considering market signals. To address these challenges, in recent years, alternative CfD designs have been proposed in the literature with the aim of enhancing market integration by decoupling payouts from real-time generation, and aligning generator incentives with market outcomes. However, the challenge is that these modified CfDs introduce basis risk, where discrepancies between reference prices and output, and actual prices and output, can lead to financial volatility. This is however unavoidable because the purpose of CfDs is to mitigate risks for renewable energy generators, while market efficiency relies on participants bearing some level of risk through price exposure, so as to incentivize optimal decision-making. This challenge underscores the complex trade-off policymakers face between market efficiency and risk mitigation, necessitating a balanced approach to the design of CfDs. Additionally, the impact of increased basis risk on various stakeholders, including generators, the government, consumers and financial institutions, highlights the need for a nuanced understanding of financial volatility and regulatory implications of alternative CfD designs.

    Dächerschachttrockner werden weltweit in der Landwirtschaft zur Trocknung verschiedenster Getreidearten sowie Mais und Reis eingesetzt. Im Vergleich zu anderen Trocknungsverfahren weist das Trocknen in Dächerschachttrocknern noch ein deutliches Potenzial zur Steigerung der Energieeffizienz auf. Der vergleichsweise hohe Primärenergieverbrauch wird überwiegend durch ungleichmäßige Trocknung hervorgerufen, die sich weniger auf Ursachen wie eine mangelhafte Trocknerregelung als auf ein ungünstiges Trocknerdesign und unzureichende Isolierung zurückführen lässt. Zur Optimierung der verarbeitenden Prozesse in agrartechnischen Anlagen werden immer häufiger numerische Methoden angewendet. Ein hohes Potenzial zur Effizienzsteigerung von Dächerschachttrocknern bietet die Optimierung der Trocknergeometrie. Im Folgenden werden die Methoden der Computational Fluid Dynamics (CFD) und der Diskreten-Elemente-Methode (DEM) verwendet, um den aktuellen Stand der Technik numerisch zu untersuchen. ; Mixed flow dryers (MFD) are widely used in agriculture for the drying of various crops including maize and rice. As compared to other drying methods in the industrial drying, mixed flow dryers still have considerable potential for improving energy efficiency. The comparatively high primary energy consumption is mainly caused by uneven drying, which, in turn, is caused less by poor dryer control rather than by unfavorable dryer design. In order to optimize the processes in agricultural engineering, such as the mixed flow dryer, numerical methods are being increasingly used. Optimization of the dryer geometry provides a high potential to further increase the efficiency of MFD. In the following, the methods of Computational Fluid Dynamics (CFD) and the Discrete Element Method (DEM) are used to investigate the state of the art.

    Der Dächerschachttrockner wurde in den letzten Jahren hinsichtlich der Trocknungseffizienz, Regelungstechnik und Leistungssteigerung vielfach analysiert. Dennoch besteht erheblicher Optimierungsbedarf bezüglich Energieeffizienz und Gleichmäßigkeit der Trocknung. Zur Analyse des spezifischen Energieverbrauchs und der Homogenität des Trocknungsprozesses wurden thermodynamische Prozesszustände anhand der konventionellen Trocknergeometrie numerisch und experimentell analysiert. Aus den gewonnenen Ergebnissen wurde eine neue Trocknergeometrie entwickelt, mit der eine deutliche Effizienzsteigerung erreicht werden soll. Wie die strömungsmechanische Analyse des ersten Designentwurfs ergab, ist weiterer Entwicklungsbedarf bis zur Praxisüberführung erforderlich. Während im Kernflussbereich in der Trocknermitte gleichmäßige Strömungsbedingungen nachgewiesen werden konnten, ist die Konstruktion in den wandnahen Bereichen zu optimieren. ; The mixed-flow dryer has been a matter of investigation many times regarding drying efficiency, dryer control, and performance enhancement over the past years. However, there is still considerable demand for optimization in terms of energy efficiency and homogeneity of drying. In order to analyze the specific energy consumption and the homogeneity of the drying process, different thermodynamic process conditions have been investigated for the conventional MFD design using numerical and experimental methods. Based on the results obtained, a novel dryer design has been developed. With this, a considerable increase of efficiency is expected. As the fluid dynamic analysis of the first design draft revealed, further development is required until scaling-up and transfer into practice will be possible. While homogeneous airflow conditions could be demonstrated in the core flow region in the center of the dryer, the configuration must be optimized in the near wall regions.
