Climate

Heatwaves, droughts, and a growing population are making it more challenging to meet water demand, even in a water-rich country such as the Netherlands. By 2030, our society is estimated to need an additional 100 million cubic metres of drinking water per year. A membrane technology studied at the University of Twente could turn the North Sea into a source of fresh water, preventing water shortage in the future. But Prof. Wiebe de Vos asks, “Is this the smartest choice?”

In Spain, the lights went out for millions of people. Not because of a cyber attack, but because of... sunlight. Researchers at the University of Twente see this as a lesson in systems thinking: sustainable solutions require smart direction. And that involves more maths than you might expect.

Losing everything in a matter of hours. Your house underwater, no safe place to go. For millions of people around the world, this is not an exception but a reality that happens more often than we think. Even in Europe, disasters are becoming more frequent, and it is becoming increasingly clear how vulnerable our homes are.

At sunrise, deep in Ghana’s tropical forest, a camera 40 metres above ground wakes up. It captures a treetop bursting into bloom, or not... A small detail in a vast green landscape, but one that holds a crucial clue to understanding how our climate is changing.

The energy transition requires action. Not just from policymakers or engineers, but precisely from the people who have to do it: the installation engineers, work planners and technicians. They are the key to change. But how do you give them space to learn the necessary skills as well as to innovate?

What if preparing for climate change could be as simple as playing a game? Cities everywhere are dealing with flooding, but not everyone knows what they can do to help. Sustainable Drainage Systems (SuDS), like rain barrels and green roofs, could make a huge difference. But how do you educate people about them? My name is Kees, and I am participating in experiments to learn more about the research at the University of Twente. In this Kees Study, I participated in the research of Dr. Carissa Champlin from the Urban and Regional Planning department at ITC.

From the tyres that keep our cars safely on the road to the soles of our shoes that provide comfort with every step – rubber is everywhere. But what makes this material so essential to our daily lives? In this story, we delve into the world of rubber alongside Professor Dr Anke Blume, an expert in elastomer technology at the University of Twente, to understand its many uses and why it matters so much.

Batteries are everywhere. In your pocket, in your car and in lots of other places. Yet, despite their ubiquity, batteries are far from reaching their full potential. They degrade over time, charge slowly and are often made of unethically sourced or environmentally harmful materials. Prof. Mark Huijben and his Research Group are looking into novel battery materials to extend battery life and improve performance across applications, from smartphones to heavy machinery.

In the heart of the Netherlands, among the centuries-old trees of the Veluwe, a new way of studying our planet is taking shape. Using advanced sensors, Paul Vermunt is comparing mathematical models with satellite data. His ultimate goal is to enable satellites from among other ESA to measure the water content in forests.

Did you know that in winter, solar panels produce only 10% of their summer output? In a country like the Netherlands, where we lead the world with 3.5 solar panels per person, this seasonal drop is a major challenge. Why do solar panels produce so little energy in winter? And what can we do about it?

At Citizen Farm Herenboeren Usseler Es, farmers are exploring how data can help them adapt to climate change challenges, such as unpredictable weather and longer growing seasons. Researchers from the University of Twente are helping by providing them with more precise data for better-informed farming decisions. The goal is to enhance local food production while offering valuable insights for farms around the world.

When you think of protecting our coasts, you probably think of dikes and seawalls. But did you know that mangroves, a special type of tree that grows between land and sea, also play an essential role in coastal protection? In this story, Erik Horstman, associate professor of Civil Engineering, tells you how these unique trees can be the key to defending our coasts against rising sea levels and extreme weather conditions.

The Netherlands faces a water crisis: too much water, a shortage of water, agricultural fertilisers, and industrial pollution such as PFAS and medicine residues threaten our drinking water supply. Some new businesses are already denied drinking water connections; new residential areas may soon meet the same fate. It is crucial to invest in water technology for a sustainable future.

As the world switches to renewable energy, the electric grid — originally designed for the stable energy flows from centralised fossil fuel power plants — is struggling to keep up. Electric vehicles, heavy machinery, and fluctuating sources like solar and wind are putting more strain on the grid. Could blue and green hydrogen be a solution to keep the lights on and machines running?

In this story, Dr. Yashar Hajimolana, Assistant Professor Energy Systems Integration at the University of Twente, explains how hydrogen can contribute to a more sustainable and stable energy system.

The switch from fossil fuels to renewable energy is going to need some nifty technology that depends on chemical elements that we have not used much before, and most of these come from minerals in rocks in the Earth’s crust. Five of these minerals stand out as Earth’s potential lifesavers.

The province of Overijssel is known for its robust agricultural and animal-farming activities. But the bustling livestock farms come with a cost. The animals produce an overwhelming amount of manure, leading to water pollution and harmful emissions. But what if this ‘waste’ could become a source of energy?

How can we make our holidays more sustainable? A question that concerns many engineers, scientists, and citizens. Emissions need to decrease, but in the aviation industry, that's not so simple yet. Research at the University of Twente is investigating a promising technology that could lead to hydrogen-powered airplanes: cryogenic superconductivity.

A looming shortage of clean drinking water is screaming for innovations in water treatment. The Waterlab of the Membrane Science and Technology cluster gives an insight into possible solutions.

Bitcoin, non-fungible tokens (NFTs), and other popular blockchain innovations represent our shift to a digital society. But this transition comes at a cost. The emissions generated by these blockchain technologies from the year 2021 alone are responsible for around 19,000 future deaths. This alarming statistic raises many questions: How is this possible and what can we do about it?

The Netherlands has been fighting a battle against water for centuries. This symbolism of water as the enemy was popular among 20th-century engineers. In the 21st century, there is more focus on natural processes, and we speak of water management instead. But what will the Dutch water landscape look like in another century?

Can we limit global warming to 1.5 oC? Unlikely, if you'd ask Debra Roberts. The co-chair of the Intergovernmental Panel on Climate Change (IPCC) is already brainstorming about a plan B. What could be our next steps?
