JUST PUBLISHED: Study number 58 on hydrogen for heating. It concludes that 1) heating with hydrogen more expensive than heat pumps 2) the required quantities of hydrogen are not available and unlikely to become available soon enough 3) there is a risk of delay of roll-out of tried and tested technologies Study by Borderstep Institute for Innovation and Sustainability gGmbH and Scientists For Future #S4F#S4F here: https://lnkd.in/eB7iTXHu In December I published my meta-review of 54 studies on hydrogen home heating assessing all independent studies on this subject.

I recently read about the TRANSCRITICAL CO2 HEAT PUMP, a technology that's pushing the boundaries in sustainable energy solutions. The paper I explored provided a detailed look at how these high-capacity heat pumps operate, focusing on key components like the shaft, rotor, and motor, and the innovative use of CO2 as a refrigerant. The paper's technical depth was a challenge, but it was rewarding to grasp the mechanics behind this eco-friendly alternative. Understanding the benefits and challenges of using CO2 highlighted the balance of innovation and practicality in this field. I'm grateful to the authors, Leonhard Wolscht, Reto Somaini, Emmanuel Jacquemoud, and Philipp Jenny from MAN Energy Solutions Schweiz AG in Zurich, for their comprehensive research in "FULL-SCALE DEMONSTRATION AND VALIDATION OF A 35 MW TRANSCRITICAL CO2 HEAT PUMP." As we navigate towards a sustainable energy future, technologies like these play a pivotal role. This exploration has not only expanded my knowledge but also fueled my enthusiasm for contributing to greener energy solutions in future endeavors. #CO2 #HeatPump #TRANSCRITICALCO2 #energyengineering

Recent paper (https://lnkd.in/dM35uqiu) on degradation aware energy management of hydrogen and reversible fuel cell-based microgrids (DOI: 10.1016/j.ijhydene.2024.03.339).

The HANNOVER MESSE reopens its doors on April 22. The most important industrial fair brings experts from mechanical engineering, the electrical industry and energy economy together to discuss the most important questions regarding climate neutrality.   At Hannover Messe 2024 we will present our application-oriented developments for fuel processing from all conventional and renewable fuels.   One of our topics at the Fraunhofer joint booth in hall 2 booth B24 is ammonia-based systems for stationary and decentralized energy supply. IMM has developed ammonia cracking systems to supply hydrogen for fuel cells and engines using different energy sources for heating of the cracking reactor. For these systems IMM has developed unique ammonia cracking catalyst coatings, which are highly active and stable. In combination with IMM’s microreactor technology, the developed ammonia cracking reactors are much more compact compared to conventional technology due to higher catalyst utilization and better heat management.   For detailed information check out our website 👉 https://lnkd.in/e5rcWu3n   #ammonia | #hydrogen | #hydrogentechnology | #energysupply | #Fraunhofer | #WeKnowHow | #FraunhoferHM24

Sector coupling and decarbonization (Article in Energy) Sector coupling is gaining international attention as a means to drive decarbonization in many countries worldwide. Our study simulates 27 sector coupling technology combinations and then evaluates their efficacy in meeting Germany’s CO2 emission targets for 2030, 2045, and 2050, respectively. Our findings show that ambitious technological pathways involving disruptive innovations in multiple sectors can substantially contribute to the decarbonization of the German energy system. Using a scoring system that incorporates technical and socioeconomic indicators, we reveal the relation between reductions in CO2 emissions and multi-criteria-based scores assigned to specific sector coupling scenarios. Our results favor emission reductions from both a socio-economic perspective and a purely economic one, and they highlight the benefits of disruptive sectoral linkages in achieving emission reduction targets. Nevertheless, none of the technology combinations analyzed here meet the ambitious German emission targets. The article is the outcome of extensive data collection and simulation efforts. It appeared in the prestigious journal Energy (Elsevier). Co-authors are Jonas Beckmann and Kai Klöckner. #decarbonization #energy #RWTHAachen #sectorcoupling #sustainability
