Sustainability - Start-up Magneto is developing an environmentally friendly alternative for cooling systems that uses patented magnetocaloric material.
Cooling systems are indispensable. Refrigerators enable our food to last longer. Medicine is also stored in these systems. Air conditioners cool our homes and buildings. However, the energy consumption of these cooling systems and the refrigerant gases that leak from them are what is causing more than ten percent of the greenhouse effect, states Ivo Dusek, managing director of Magneto. The TU Delft spin-off is working on an environmentally friendly variant for cooling systems. For this, the start-up is making use of patented magnetocaloric material that does not require any rare metals. Last month, the start-up participated in the Finnish start-up event Slush.
More about Insightful Innovators
The โInsightful Innovatorsโ series is an initiative of 4TU.Federation and Innovation Origins. This is where you can read the stories behind entrepreneurial students at the four Dutch technical universities and their ambition to make the world a bit more beautiful. They are the driving force behind innovation in the Netherlands.
โOur material heats up when it is magnetized and cools down when you remove that magnetism,โ Dusek explains. Professor at TU Delft Ekkes Brรผck invented the material more than 20 years ago, after which TU Delft has since filed several patents for the material. Magneto is marketing several uses of the technology. For this, the start-up is targeting hardware manufacturers that are interested in developing heat pumps.
One system
โFrom the powdered form of the material, the company 3D-prints a gauze-like structure. โA solid material ( composed of manganese, iron, phosphorus and silicon, ed.) transfers warmth and cold to an appliance,โ Dusek goes on to explain. โTo do this, we let water flow through the mesh-like material. This way, we can maximize the efficiency of the heat and cold transfer. Our technology is capable of reaching a very broad temperature range: from -80 Cยฐ up to +200 Cยฐ. This also means that it has a wide range of applications.โ
โThe material in the heat pump cools or heats the water that flows through it. All you have to do is change the direction of the flow.โ A separate boiler, air conditioning system, refrigerator or heat pump will eventually no longer be needed with the Magneto system, Dusek points out. โOur dream is to develop one system that takes care of the entire thermal management of a house or building.โ In order to shed light on the problem that cooling poses, Dusek goes back in time.

A heat pump can be used for cooling just fine by reversing the way it works, as an analysis by the Fraunhofer Institute for Building Physics IBP has shown.
Possibilities
โUntil maybe a hundred and fifty years ago, people used ice to keep things cool. Ice that they collected in the winter and stored in their basements.โ A hundred years ago, the refrigeration industry used propane and ammonia to cool things. โThese turned out to be flammable (propane) and toxic (ammonia). Both gases have since been banned. However, the new kinds of gases caused holes in the ozone layer. Present-day gases, though, are safe for humans and do not cause any holes in the ozone layer. However, the greenhouse effect that they cause is much bigger, sometimes as much as ten thousand times more than a CO2 molecule.โ
The potential of the magnetocalorific material is formidable. Dusek: โIt can be used to liquefy hydrogen. At extremely low temperatures, it can also be used in the pharmaceutical industry. And itโs also really well suited to industrial processes that are carried out at higher temperatures.โ
Given that the opportunities for this technology are so enormous, the start-up decided to involve companies โ prospective clients โ in the development process. โThey possess knowledge of the target market, and they understand the needs that are out there. We are teaching them how they can develop a product with our technology.โ

Data centers and supermarkets
โFor example, we are now in talks with a French manufacturer that has data centers as clients. We are working with them to see how they could translate our technology to their market: what temperature range is needed? What would the yield be? How much would it cost? Right now, we are doing a feasibility study with this French company.โ
Dusek also plans to conduct a pilot study at several supermarkets. โ Itโs an interesting market for us. Supermarkets are under a lot of regulatory pressure. As a result, they are stepping over to systems that are far from ideal in terms of safety and efficiency.โ For that reason, a consortium has been set up with a French company and a Dutch refrigeration systems company. โWe want to bring the technology to supermarkets with the help of these companies.โ
According to Dusek, the difficult thing about working on an innovative piece of deep tech is โthat there isnโt a market for it yet.โ โWe have got a fantastic material that has a ton of potential, but there isnโt any demand for it yet,โ he adds.
โItโs a bit of a chicken-and-egg situation. You have to develop the market at the same time that you are developing the product.โ That is what Dusekโs area of focus is.

Europe
Dusek worked for Vodafone for the first ten years of his career. First based out of Prague, and later based in Dar es Salaam, Tanzania. The Czech held various commercial positions within the telecom company. โFrom sales, marketing, customer service to strategy. I have a good grasp of business. I know how to build a company.
For one thing, Dusek started a renewable energy company in Africa. That company then also went on to establish itself in Southeast Asia. Dusek and his family lived in Myanmar for two years and in Vietnam for a year. โWe werenโt quite sure if either of these places were really home to us. So, we decided to go to Europe.โ
His Canadian wife also found a job in the Netherlands. This is why Dusek looked for an opportunity to work there as well. โI really love the energy of start-ups. So, I was looking for a start-up with a good product or a good idea for a product. A start-up that I could then help launch onto the market.โ He eventually ended up with Bowei Huang and Michael Maschek, the founders of Magneto who were working on technology at TU Delft.

Valuable
The start-up also receives a lot of support from the Dutch government, Dusek points out. In the form of loans and grants from the Province of South Holland, among others, but also through network contacts. Dusek also speaks very highly of the Yes Delft incubator. โA very well-organized incubator. Thereโs also a lot of knowledge there thatโs very useful to us.โ
Through Delft Enterprises, an organization that supports start-up/spin-offs from TU Delft, Dusek was invited to join the delegation to Slush. On his return, he enthusiastically announced that his LinkedIn profile had grown much larger over those two days than it had in the past two years.
โEverything was so well organized. You knew before and during Slush exactly what was going to happen and who we could talk to. This meant we could do exactly what we came for: build a network of potential investors and business partners outside of the Netherlands.โ In addition to forging new contacts, Magneto also leveraged Slush to launch a new investment round.
Dusek spoke with twenty investors. โYou really only have time to establish some common ground in order to arrange a follow-up meeting. Nothing less, nothing more. We are now at the stage where we can start working out more details. Normally it would take us at least a couple of weeks to make these first few contacts. Really valuable, in other words.โ
