Improved Energy Efficiency of Power‐to‐X Processes Using Heat Pumps Towards Mobility Sector Defossilization

چکیده
Combining Power-to-X (PtX) processes with high temperature heat pumps (HTHP) can significantly increase their energy efficiency. Evaluating the example of oxymethylene ethers (OME) production from H2 via H2O electrolysis and captured CO2 air shows that by upgrading waste streams using HTHP, a process overall efficiency higher than 61 % be achieved compared to 30 in conventional integrated processes. Thereby, stream already covers low demand for capture direct capture, not only OME but also various PtX products. Importantly, significant lever enhancement is consideration other heat-demanding sectors. High efficiencies electrification industry are key aspects towards sustainable mobility sector.

assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Rankine cycle efficiency gain using thermoelectric heat pumps
The Rankine cycle remains the dominant method of thermal plant electricity generation in the world today. The cycle was described over 150 years ago and significant performance advances continue to be realised. On-going metallurgy research has enabled the operating pressure and temperature of the boiler and turbine to be increased, thereby improving the cycle efficiency. The ubiquitous use of t...
متن کاملSmart energy management as a means towards improved energy efficiency
The costs associated with refrigerator equipment often represent more than half of the total energy costs in supermarkets . This presents a good motivation for running these systems efficiently. In this study, we investigate different ways to construct a reference behavior, which can serve as a baseline for judging the performance of energy consumption. We used 3 distinct learning models: Multi...
متن کاملEfficiency of closed loop geothermal heat pumps: A sensitivity analysis
Geothermal heat pumps are becoming more and more popular as the price of fossil fuels is increasing and a strong reduction of anthropogenic CO2 emissions is needed. The energy performances of these plants are closely related to the thermal and hydrogeological properties of the soil, but a proper design and installation also plays a crucial role. A set of flow and heat transport simulations has ...
