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.

Ebru Alazi ‘hacked’ an enzyme-producing system in the fungus Aspergillus niger in order to produce renewable energy more easily. She manipulated the fungus, making it produce more pectinases: enzymes mainly used in the food industry and in the production of renewable energy, such as biofuels. Promotion…

On 24 May 2022, Christa Tobler gave a lecture on 'EU-Swiss Legal Relations: Why do we still not have an Energy Agreement?'

The present market regulations make it extremely risky to invest in green energy, and this is impeding the fight against climate change. This is what Oscar Kraan writes in his dissertation. PhD defence on 25 April.

How can we ensure a more resilient and sustainable supply of Rare Earths in the EU in the future?

Both the Dutch government and the European Commission dedicate an increasing share of public funding for research and innovation to mission-oriented programs, aiming to facilitate sustainability transitions. These programs typically involve support fora range of different research activities, from the…

Assistant Professor Vedran Dunjko and his team received a gift from Google to support their quantum research. The research focuses on whether quantum computers can provide new ways of understanding the mysteries of high-energy physics.

Imagine we could convert the greenhouse gas CO2 into synthetic fuels using sustainable energy. This would enable us to reduce the amount of CO2 and at the same time store wind and solar energy in an innovative way. Chemist Akansha Goyal (Leiden University) is conducting fundamental research to make…

To generate renewable energy takes more space than one might think. New research by environmental scientist Paul Behrens and master's student John van Zalk shows how much space is needed for nine specific types of energy. Biomass, hydro and wind, while vital, take up the most space. Natural gas and…

Despite the rapid progress in solar and wind energy, a completely clean energy supply remains a huge challenge. Heavy industry, aviation, shipping and road transport are not yet able to do without carbon-based fuels. To reach the climate goals, in these industries energy consumption should be CO2 neutral. In…

Huub de Groot is one of the 55 authors for the book The Colours of Energy. The book consists of Essays on the Future of Energy in Society in which leading energy thinkers explore the future of energy in society.

In order to build wind turbines and electric cars, we need tons of magnets. Currently, we import these mainly from China, which means Europe is very dependent on this superpower for the energy transition. This has to change, according to industrial ecologist René Kleijn. In the REEsilience project,…

On Friday 10 July the Towards Biosolar Cells research programme was granted a budget of 25 million euros by the Dutch Government. The Ministry of Agriculture, Nature and Food Quality recommended the programme because it will contribute to green energy, improve food supplies and a create a more sustainable…

Time-series forecasting through modelling sequences of temporally dependent observations has many industrial and scientific applications. While machine learning models have been widely used to create time-series forecasting models, creating efficient and performant time-series forecasting models is…

Governments are increasingly facilitating the roll-out of so-called “smart meters”, a technology for measuring energy consumption that are able to transmit and receive data using a form of electronic communication. However, implementation has been slow or even stalled.

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

A festive and honourable visit to our southern neighbours for professor Marc Koper. On Thursday 23 March, he received an honorary doctorate at the University of Antwerp. Koper gets the title in recognition of his expertise in the field of electrochemistry. ‘An important recognition for our research…

Overview of the main research projects at the Leiden Papyrological Institute.

On Wednesday 11 June 2025 Steffie van Gompel successfully defended a doctoral thesis and graduated.

With its Green Deal The European Union has set itself much-needed ambitious climate goals. But the energy crisis and geopolitical tensions are making these difficult to achieve. Seven researchers from the Leiden-Delft-Erasmus Universities (LDE) alliance have written a white paper offering solutions.

Both Leon Jacobse and Thom Hersbach from Marc Koper's research group obtained their PhDs cum laude. They both investigated changes on the surface of a platinum electrode. Jacobse studied this at a positive voltage, Hersbach at a negative voltage. Platinum has the potential to convert renewable energy…

How will we generate energy without further contributing to global warming? Industrial ecologist René Kleijn tells about low-carbon energy in tv and radio show Focus, and in VPRO Magazine.

A consortium of international researchers comes with a unique solution to the energy problem. By mimicking photosynthesis, they aim to produce sustainable fuels out of sunlight, water, and CO2. Their secret? ‘Soap bubbles’, says Leiden chemist Sylvestre Bonnet, who is part of the consortium.

Yuvraj Birdja converted CO2 to formic acid to store energy in a sustainable way, with different catalysts. With this new knowledge, scientists are a step closer in industrially converting CO2 to chemicals and fuels. This can help reduce CO2 emission and the greenhouse effect.

European dependence on Russian gas, earthquake damage in Groningen and the changing climate: the call for an energy transition is getting louder. This transition will be accompanied by an increasing demand for 'new' raw materials. The Geo-Resources for the Future minor looks at exactly that developm…

A wide range of metals need to be mined for solar panels, wind turbines and batteries. But the overall mining activity is set to decrease as clean energy replaces fossil fuels such as oil, coal and gas.

A team of researchers at Leiden University’s Europa Institute authored an extensive study on the potential for a Climate and Energy Union within the EU constitutional framework. The study was published by the European Parliament in December 2024.

Physicist Remko Fermin from Leiden University was awarded a Rubicon grant from NWO. He will use it to study superconducting diodes that could contribute to reducing the CO2 emission of data centres.

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

The STW project Energy Efficient Computer-Brain Interaction (principal investigator for LIACS: dr. T.P. Stefanov) has been granted. Funding for LIACS: 1 PhD student + travel/equipment budget, project duration: 4 years.

The rising energy prices cannot have escaped anyone’s notice. They have dominated the news in recent months. As a university, we too face a big challenge as the prices continue to rise.
