Lezing, Tuesday Talks: Science Insights

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

Naar schatting bestaat de wereldbevolking over twintig jaar uit ongeveer 8,7 miljard mensen, terwijl dat aantal nu 7,3 miljard is. Deze groei, gecombineerd met de bijbehorende groei in consumptie en de verbeteringen in levensstandaarden, zal resulteren in een enorme groei in de vraag naar voedsel, verbruiksgoederen,…

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

The Institute of Environmental Sciences has carried out and participates in several projects that deal with the analysis of energy systems.

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

Examining if large scale application of new energy pathways can be constrained by materials and emissions.

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

Wat zijn de belangrijkste thema's in het uitvoeren van systemen voor bio-energie ?

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.

Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

Examining the sustainability aspects of biotechnology, especially those related to the production of ethanol from biomass.

Where and how are critical materials currently used and how can this information be used to develop scenarios about their future demand.

The work in this thesis describes the fundamental role of Lkb1 as a conductor of metabolism-related processes in zebrafish larvae.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

This thesis aims to address offshore wind energy (OWE)-related environmental impacts.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

Submissions are sought for a special issue with Frontiers in Political Science that explores the conceptual and practical aspects of a ‘just’ energy transition both within and beyond Europe. In particular, contributions to the theoretical and interdisciplinary foundations of just transitions, as well…

Prof.dr. Gert Jan Kramer is bij de Faculteit Wiskunde en Natuurwetenschappen in deeltijd benoemd tot hoogleraar Sustainable Energy. Kramer is en blijft daarnaast manager Energy Futures bij Shell. Tot zijn aantreden in Leiden was Kramer hoogleraar bij de TU Eindhoven.

De huidige en toekomstige quantumcomputers vormen dezelfde uitdaging als de laser in zijn begindagen. In theorie werd voorspeld dat de laser een bron van zeer speciaal, zeer krachtig licht zou zijn. Maar in die tijd waren er geen duidelijke toepassingen voor. Critici van het idee noemden het een probleem…

De Energie survival gids van prof. Jo Hermans is nu ook in het Engels beschikbaar en bovendien is het boek volledig geüpdated. De Energy Survival Guide is een compacte en betrouwbare bron van informatie voor iedereen die op zoek is naar adviezen over de toekomst van de wereldwijde energievoorziening…

De productie van duurzame energie kost tot 1000 keer meer ruimte dan fossiele brandstoffen, becijferde milieuonderzoeker Paul Behrens in een publicatie in het blad Energy Policy. Uiteenlopende media berichtten over deze opmerkelijke uitkomst.

Bacterial biocatalysis constitutes a sustainable alternative for high-value chemicals production by enabling the utilization of renewable feedstocks.

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

HEPGAME is a research project that combines the world’s fastest computer algebra system for High Energy Physics equations, FORM, with insights from artificial intelligence. The name combines High Energy Physics and Games.

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.
