NWO financiering voor flexibele stroomvraag van elektrisch gedreven industrie

NWO financiert twee projecten waarin onderzoek gaat plaatsvinden hoe de stroomvraag van de industrie flexibel gemaakt kan worden. Daarmee sluit het beter aan op het toekomstige energieaanbod. Een van de consortiumprojecten: ‘DEFLAME’ wordt geleid door Machteld van den Broek van de TU Delft. Zon en wind leveren een variabele hoeveelheid stroom, toch vraagt de huidige industrie een vrij constant vermogen. Om de industrie voor te bereiden op een stroomaanbod met veel zon en wind zijn aanpassingen nodig. Het gaat om zowel technische, economische als sociale aanpassingen die gezamenlijk door kennisinstellingen en bedrijfsleven worden onderzocht in deze twee projecten. Ook is er aandacht voor de drempels die aanpassingen in de weg staan. Over DEFLAME DEFLAME staat voor Direct Electrification of industrial heat demand supported by FLexibility At Multiple levels and their Exchanges (DEFLAME). Het project streeft ernaar de Nederlandse procesindustrie, en dan met name de chemische en voedselindustrie, veerkrachtiger en klimaatneutraal te maken door industriële warmte te elektrificeren met flexibiliteitopties. Van den Broek: ‘Hierbij kan je bijvoorbeeld denken aan het op- of afschakelen van installaties, opslag van warmte in de ondergrond en/of opslag van elektriciteit in batterijen, zodat de industrie beter kan inspelen op schommelingen in het energienetwerk.’ Dit vereist samenwerking op verschillende niveaus: technologie, fabrieken, clusters en nationale en internationale energiesystemen. DEFLAME richt zich op het wegnemen van obstakels voor de elektrificatie van lage temperatuur warmte (tot 400°C) met efficiënte technologie. ‘Dit wordt bij heel veel processen ingezet. Warmte is nodig om ervoor te zorgen dat de juiste chemische reacties plaatsvinden, maar ook bij het drogen, distilleren en verdampen is warmte nodig. In het kristallisatieproces om suiker te maken van bieten bijvoorbeeld, of bij de winning van zout’, legt Van den Broek uit. Bij kristallisatieprocessen kan bijvoorbeeld mechanische damprecompressie gebruikt worden. In dit proces worden de dampen door een elektrisch bediende compressor samengeperst en opnieuw gebruikt om de verdamper te verwarmen. ‘Dat bespaart energie, omdat je restwarmte gebruikt en de elektriciteit kan schoon worden opgewekt. Met zon en wind heb je, anders dan met gas, een variabel stroomaanbod. Als je de industrie wilt elektrificeren moeten bedrijven en de technologie daar flexibel op kunnen inspelen, door bijvoorbeeld als cluster warmte op te slaan of flexibiliteit in te bouwen in het elektriciteitssysteem.’ DEFLAME gaat vanuit verschillende niveaus en interdisciplinair strategieën en regelingen ontwikkelen om deze oplossingen mogelijk te maken. Van den Broek: “Ik kijk ernaar uit om samen met de partners een belangrijke stap te zetten om elektrificatie van de industrie in Nederland te bevorderen. Dit is een essentieel onderdeel van de energietransitie” Consortium partners Partners in het consortium zijn: AtlasCopco, Cosun, ISPT, Nobian, Oranje Wind Power II C.V./RWE, Smart Port, Stedin, Tennet, TNO, TU Delft en TU Eindhoven.

Students Amos Yusuf, Mick Dam & Bas Brouwer winners of Mekel Prize 2024

Master students Amos Yusuf, from the ME faculty (Mick Dam, from the EEMCS faculty and graduate Bas Brouwer have won the Mekel Prize 2024 for the best extra scientific activity at TU Delft: the development of an initiative that brings master students into the classroom teaching sciences to the younger generations. The prize was ceremonially awarded by prof Tim van den Hagen on 13 November after the Van Hasselt Lecture at the Prinsenhof, Delft. They received a statue of Professor Jan Mekel and 1.500,- to spend on their project. Insights into climate change are being openly doubted. Funding for important educational efforts and research are being withdrawn. Short clips – so called “reels” – on Youtube and TikTok threaten to simplify complex political and social problems. AI fakes befuddle what is true and what is not. The voices of science that contribute to those discussion with modesty, careful argument and scepticism, are drowned in noise. This poses a threat for universities like TU Delft, who strive to increase student numbers, who benefit from diverse student populations and aim to pass on their knowledge and scientific virtues to the next generation. It is, therefore, alarming that student enrolments to Bachelor and Master Programs at TU Delft have declined in the past year. Students in front of the class The project is aimed to make the sciences more appealing to the next generation. They have identified the problem that students tend miss out on the opportunity of entering a higher education trajectory in the Beta sciences – because they have a wrong picture of such education. In their mind, they depict it as boring and dry. In his pilot lecture at the Stanislas VMBO in Delft, Amos Yusuf has successfully challenged this image. He shared his enthusiasm for the field of robotics and presented himself as a positive role model to the pupils. And in return the excitement of the high school students is palpable in the videos and pictures from the day. The spark of science fills their eyes. Bas Brouwer Mick Dam are the founders of NUVO – the platform that facilitates the engagement of Master Students in high school education in Delft Their efforts offer TU Delft Master Students a valuable learning moment: By sharing insights from their fields with pupils at high school in an educational setting, our students can find identify their own misunderstandings of their subject, learn to speak in front of non-scientific audiences and peak into education as a work field they themselves might not have considered. An extraordinary commitment According to the Mekel jury, the project scored well on all the criteria (risk mitigation, inclusiveness, transparency and societal relevance). However, it was the extraordinary commitment of Amos who was fully immersed during his Master Project and the efforts of Brouwer and Dam that brought together teaching and research which is integral to academic culture that made the project stand out. About the Mekel Prize The Mekel Prize will be awarded to the most socially responsible research project or extra-scientific activity (e.g. founding of an NGO or organization, an initiative or realization of an event or other impactful project) by an employee or group of employees of TU Delft – projects that showcase in an outstanding fashion that they have been committed from the beginning to relevant moral and societal values and have been aware of and tried to mitigate as much as possible in innovative ways the risks involved in their research. The award recognizes such efforts and wants to encourage the responsible development of science and technology at TU Delft in the future.

New catheter technology promises safer and more efficient treatment of blood vessels

Each year, more than 200 million catheters are used worldwide to treat vascular diseases, including heart disease and artery stenosis. When navigating into blood vessels, friction between the catheter and the vessel wall can cause major complications. With a new innovative catheter technology, Mostafa Atalla and colleagues can change the friction from having grip to completely slippery with the flick of a switch. Their design improves the safety and efficiency of endovascular procedures. The findings have been published in IEEE. Catheter with variable friction The prototype of the new catheter features advanced friction control modules to precisely control the friction between the catheter and the vessel wall. The friction is modulated via ultrasonic vibrations, which overpressure the thin fluid layer. This innovative variable friction technology makes it possible to switch between low friction for smooth navigation through the vessel and high friction for optimal stability during the procedure. In a proof-of-concept, Atalla and his team show that the prototype significantly reduces friction, averaging 60% on rigid surfaces and 11% on soft surfaces. Experiments on animal aortic tissue confirm the promising results of this technology and its potential for medical applications. Fully assembled catheters The researchers tested the prototype during friction experiments on different tissue types. They are also investigating how the technology can be applied to other procedures, such as bowel interventions.
