ENGIE New Ventures Invests in MAGNOTHERM, Raising Seed Financing to €6.8M

ENGIE New Ventures (ENV), the investment fund of ENGIE Research & Innovation for innovative start-ups that accelerate the energy transition, has invested in MAGNOTHERM.

Our disruptive technology, which can also be used for cold production (refrigerators, air conditioners), uses magnetic refrigeration to liquefy hydrogen, allowing it to be transported and stored in larger quantities. The process is based on the magnetocaloric effect (MCE), which changes the temperature of a magnetic material exposed to an external magnetic field.

MAGNOTHERM’s hydrogen liquefaction technology is currently in the development phase. With this investment, ENGIE aims to play an active development role by drawing on the knowledge and expertise of the Lab Crigen , ENGIE’s R&D centre for green gases (hydrogen, biogas, liquefied gases). ENGIE and MAGNOTHERM are also members of a European consortium as part of the EU-funded HyLICAL project, which aims to build Europe’s first magnetic liquefactor of hydrogen.

MAGNOTHERM’s technology will cut hydrogen liquefaction costs, making it economically viable. This paves the way for the emergence of a hydrogen transport supply chain for the development of the entire hydrogen sector. This ambition falls under ENGIE’s broader strategy of leading the energy transition with a strong decarbonisation policy, and of achieving carbon neutrality by 2045.

“ENGIE New Ventures’ investment in MAGNOTHERM is an important step for ENGIE in developing a renewable hydrogen supply chain ecosystem that aims to produce, liquefy, and transport this hydrogen throughout Europe. Their technology could constitute a breakthrough innovation for hydrogen liquefaction, and ENGIE will support its development for future industrialisation via its Research Centre,” says Valérie RUIZ DOMINGO, ENGIE’s Group Vice-President for Hydrogen.

“We are very happy about the valuable support from one of the world’s largest energy companies! Now, hopefully, we will be able to answer the question of how we can transport green hydrogen to or within Europe and use it more quickly much faster!” adds Timur SİRMAN , Co-CEO of MAGNOTHERM .

ENGIE and MAGNOTHERM are convinced: The green transformation requires not only green hydrogen, but also the associated infrastructure for safe and efficient transport. Industries such as aviation, shipping and other heavy-duty applications might benefit massively from hydrogen liquefaction based on magnetocaloric cooling technology and reach net zero faster. MAGNOTHERM’s goal is to offer a solution that is scalable for industrial scale. The construction of the prototype plant for the liquefaction of hydrogen on an industrial scale, mentioned at the beginning, is planned to take place as early as 2025.

This joint effort should help to meet the coming industrial needs in a more resilient way: Several studies¹ predict that by 2030, when the first magnetocaloric hydrogen liquefier will be at the industrial scale, the total demand for hydrogen amounts to 40 – 90 terawatt hours per year – corresponding to an electrolysis capacity of 22 to 37 gigawatts² which compares to around eighty times the currently installed global electrolysis capacity.

€6.3M Seed Round to Commercialize First Sustainable Refrigerator

€6.3M Seed Round to Commercialize First Sustainable Refrigerator

MAGNOTHERM closes €6.3 million seed funding round to mass produce first sustainable refrigerator

The climate tech startup MAGNOTHERM has successfully closed its seed financing of 6.3 million with lead investor Extantia, Revent, BMH Beteiligungs-Managementgesellschaft Hessen, LAUDA Dr. R. WOBSER Beteiligungs-mbH as well as Katrin Pucknat, Arne Stoschek, Willi Tscheschner,and Christoph Behn through the business angel club better ventures. The investment will be used for the series production of the world’s first sustainable refrigerator, which already has a paying clientele.

MAGNOTHERM develops and builds highly efficient and sustainable cooling systems based on magnetic materials. Instead of climate-damaging, explosive or toxic cooling gases, the climate tech startup uses a temperature-active metal that cools down a mixture of water. The founders have already received several awards for their work, including the Hessischer Gründerpreis.

MAGNOTHERM revolutionizes the climate-damaging cooling market

The energy saving potential in the cooling market is huge. Commercially available cooling systems cause about 10 percent of global greenhouse gas emissions. In addition, there are emissions from the refrigerants in these cooling systems, such as hydrofluorocarbons, which have up to 600 times the global warming potential of carbon dioxide and are regularly released when they are scrapped. Replacing these harmful refrigerants could avoid 1.3 gigatons of CO2e per year. This is exactly where MAGNOTHERM comes in. MAGNOTHERM’s revolutionary technology has many potential applications for any type of refrigeration – from refrigerators to air conditioners to hydrogen liquefaction.

With the new capital, the founders plan to go into mass production of their already commercially successful beverage refrigerator, introduce a 3kW refrigerated shelf for food retail, and have their magnetic hydrogen liquefaction validated in the lab with the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). The startup’s big goal: to establish their solution as an industry standard to combat climate change.

MAGNOTHERM develops sustainable cooling systems thanks to magnetic cooling

“Our magnetic cooling is not only up to 40 percent more efficient than conventional solutions, but also produces no direct greenhouse gases. With POLARIS, we have developed the first magnetic beverage cooler, making us the world’s first commercial supplier of this technology at room-temperature. With the financing, we are pushing ahead with the series production of our beverage cooler and accelerating the market development for sustainable refrigerated shelves in food retail,” comments Timur SİRMAN, Co-CEO of MAGNOTHERM, on the financing round.

“We have been following the team at MAGNOTHERM for a long time and are really impressed with them! Their highly efficient and sustainable cooling systems are the result of years of research, and they are pioneering a technology that will be part of everyday life in the future – be it through the preservation of products or as a key element of the hydrogen economy. As true pioneers who have found a smart solution to an important climate problem, Timur and Maximilian are poised to accelerate their journey to commercialize a scientific breakthrough,” said Torben Schreiter, Partner at Extantia Capital.

“The issue of cooling will become more important in an increasingly warmer world. But conventional cooling systems consume too much energy to support this change in a sustainable way. We must now do everything we can to make cooling technology massively more energy efficient. MAGNOTHERM shows that this is possible using deep tech,” says Tina Dreimann, founder and managing director of better ventures.

“As the world market leader, we want to improve the world together with exact temperatures – that is our vision and we put it into practice every day. In the future, energy-efficient systems will be needed that conserve resources and minimize climate-damaging emissions. MAGNOTHERM is taking a decisive step forward here, which fits well with our technological competence as a world market leader. With our investment, we are laying the foundation for successful cooperation between start-up and industry and can benefit from each other,” states Managing Partner of LAUDA, Dr. Gunther Wobser.

“We are thrilled to have supported MAGNOTHERM as financial advisor with their successful seed round“, says Laurent Guyard, CEO of Proof of Concept Partners.

Multi-award-winning startup that combines science with practice

MAGNOTHERM develops and builds highly efficient and sustainable cooling solutions based on magnetic materials. Instead of gas-vapor refrigerants, the novel magnetic cooling technology uses the magnetocaloric effect in iron-based alloys. MAGNOTHERM was spun out of Technische Universität Darmstadt in 2019. With Co-CEOs Timur SİRMAN and Dr. Maximilian Fries, CTO Dimitri Benke, CPO Jeffrey Pickett, and Advisors Prof. Dr. Oliver Gutfleisch and Dr. Tino Gottschall, the six-member founding team is made up of scientists in physics and materials science. Together with their team, which combines special know-how from the fields of materials science and plant engineering, they want to revolutionize the cooling industry – and above all make it sustainable.
