The defossilization of the electricity and heat supply in chemical industry poses a significant challenge. In particular, intended feed-in volatile renewable into processes may conflict with need for constant, secure affordable plants. Adapted concepts operation cogeneration plant, which is located at site, play central role. present work defines so-called ideal-typical utility infrastructure (...

some engravings are meant to be adored and some possibly abhorred. teacher cognition, as a meant-to-be-praised engraving, is defined by borg (2003, p. 81) as “the unobservable cognitive dimension of teaching what teachers know, believe, and think.” this concept in teaching has recently gained momentum meaning that teachers learn so much about their teaching through the vast experience they have...

With “defossilisation” at the core of many sustainability goals within industry, exploration new synthesis routes to chemicals has never been more vital. As part their Clean Futures initiative, Unilever Home Care published Carbon Rainbow, a scheme which categorizes chemical sources into different “colors,” depending on derivation. One Rainbow is phase out non-renewable “black” carbon from suppl...

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 proce...

Abstract With the progressive defossilization of our industry, hydrogen (H 2 ) has been identified as a central molecule to store renewable electricity. In this context, ammonia (NH 3 is now rapidly emerging promising carrier for future. This game change indirectly impacts field fine chemistry where hydrogenation reactions are widely deployed. particular, possibility performing using directly i...

Electricity-based jet fuel from renewables, also labeled sustainable aviation (SAF), is expected to play a key role in the defossilization of aviation. The realization first plants for production such power-to-liquid (PtL) fuels imminent. This raises challenge an effective PtL supply chain design, which addressed this work. A novel optimization approach introduced that enables integrated select...

Long-term transition pathways to a low-carbon energy system are analysed by applying the model REMod. All in all, paper contributes current research through an innovative scenario approach, using assumptions for societal trends and quantitative results scenarios, analysing paths towards climate neutrality defossilization 2050. In case study of Germany, these drivers influence technology composi...

Thermocatalytic CO2 hydrogenation to methanol is an attractive defossilization technology combat climate change while producing a valuable platform chemical and energy carrier. However, predicting the performance of catalytic systems for this process remains challenge. Herein, we present machine learning framework predict catalyst from experimental descriptors. A database Cu-, Pd-, In2O3-, ZnO-...
