aerogel-it visiting IBIH in China

Last week Marc and Dirk of the aerogel-it team had the pleasure to visit leading Chinese aerogel and thermal barrier manufacturer IBIH Advanced Materials. IBIH celebrated their their 10th anniversary and hosted the official opening of a brand-new joint international aerogel R&D center.

Also present were Hamburg University of Technology president Prof. Dr. Andreas Timm-Giel and vice-president Prof. Dr. Irina Smirnova. Both were visiting China to build new collaborations. They were joined by fellow aerogel compatriots Keey Aerogel with Francisco RUIZ, new CEO Stéphane Reyniers and his predecessor Michael O’Connor.

The IBIH story

Starting from zero, the IBIH team around CEO Dr. Yunhong Wang has established itself as the leading provider of aerogel thermal barriers for EV batteries. Through hard work and grit, they have become market leader in China. Founder and chairman Mr. Tian emotionally spoke about how hard the journey had been – which resonated with the aerogel-it and Keey Aerogel teams.

In addition to the very touching anniversary celebration, the colleagues of IBIH very kindly and proudly gave their guests tours of their various R&D and production facilities. A pleasure for the assembled aerogel experts who were impressed by the capabilities. Furthermore, aerogel-it and IBIH identified potential collaborations. And in addition to the many business-related events, the IBIH organizing team around Haibing Dong, Yitian Du杜倚天 and Meng Xiao hosted the visitors for an amazing week in Beijing and surroundings!

Thermal barriers and aerogels

Thermal barriers are – as of now – necessary to contain possible thermal runaway from EV battery cells. In this way, they prevent chain reactions across the battery and help to protect passengers of electrical vehicles. Aerogel has been found to provide an excellent solution for two reasons:

1️⃣ Due to its excellent thermal insulation performance, the material shields against thermal runaway even if very thin which saves space and increases vehicle range.

2️⃣  The aerogel structure can deal with battery cell “breathing” and expansion over the battery lifetime.

There was some hope for solid-state batteries to get rid of the runaway problem and with it the thermal barriers. But the involved high energy densities still bear risk. Therefore, aerogels may be here to stay.

Heat shields have already become the largest aerogel application. The aerogel market is now heavily contested between older players such as Aspen Aerogels and Cabot and younger players, especially in Asia and China. Interestingly, there is currently no aerogel production in Europe (something that aerogel-it and Keey are driving to change with our step-change and cost-saving technologies).

Already around 5 million electrical cars drive with 200 million aerogel thermal barriers produced by IBIH. Now they are expanding globally and hired a stellar set of people to do it. Quite a success story that we can only congratulate them on!

Inauguration of UNU CampusLab “Circular Economy” at TUHH

Last week, Marc and Dirk represented aerogel-it at a very special occasion: The inauguration of the new “CampusLab Circular Economy” at Hamburg University of Technology. This event formed part of the 1st Annual United Nation University Hubs Meeting. The inauguration was headed by TUHH president Prof. Dr. Andreas Timm-Giel and Vice President Prof. Dr. Irina Smirnova.

CampusLab project manager Dr. Baldur Schroeter did an excellent job in setting up the lab as well as preparing and executing the inauguration ceremony (despite the many challenges).

aerogel-it was thrilled to be part of the inauguration of the CampusLab Circular Economy at TUHH. The team is very happy and honored to be a part of this great story at TUHH!

Background

Next-generation silica aerogel produced at pilot scale

After his recent success with the bioaerogel, Alberto also single-handedly produced ~1000 liters of our next-generation silica aerogel at pilot scale on our plant at TUHH. This is a another major milestone for us.

We have concentrated all of our 15-20 years of aerogel experience and chemical expertise into the design of this material. Our next-generation silica aerogel is a hybrid material made of silica and biopolymers. We like to call it “biomineral” or “LSMA” – for now. There will be some re-branding in the future as we refine the material for various applications. Whatever its name – our customers and partners already really like it.

We see a number of important advantages:

1. If you have worked with current silica aerogels, you will know how dusty and brittle they are. This has always been a big problem for the applicators and integrators. We have tackled this: Our biomineral silica aerogel is not dusty, and it is mechanically stable. This makes it much easier to handle and work with.

2. Due to the improved mechanics, completely new types of aerogel composites can made out of our biomineral silica aerogel. This was difficult to impossible with current silica aerogels! Check out the photo.

3. Recycling and re-use become much more feasible, since the biomineral silica aerogel does not break down into dust quickly.

4. High cost is a problem of current aerogel materials and limits their acceptance. With our raw material choice together with our proprietary manufacturing process, we push for lower cost of aerogel materials. This is one of our core missions.

5. Current silica aerogels suffer from high CO2 footprints. Due to raw material choice and our proprietary manufacturing process, we expect a strongly reduced CO2 footprint for our biomineral silica aerogel. This will be especially important in the Construction industry with its ever stricter GWP targets. But of course improved sustainability is great in any application.

6. We can produce it with the same proprietary manufacturing process as our other aerogel materials – such as our bioaerogels. Multi-purpose production has been validated.

We are now going through the piloting phase and move towards showcases with our partners and customers. Really exciting times for the team!

Cellulose aerogel produced at pilot scale!

Last week, the aerogel-it team could celebrate reaching several milestones: Alberto has single-handedly achieved production of 1000 liters of cellulose aerogel beads at pilot scale using our pilot plant at Hamburg University of Technology!

Why is this important to us?

1️⃣ It is likely the largest quantity of bioaerogel ever produced. Alberto may very well have achieved a world record – especially since he did it completely on his own!

2️⃣ Much of the cellulose bioaerogel is required for our BIOVIPWALL project as part of the iclimabuilt (an EC Horizon Europe project). It will be converted to bioaerogel vacuum insulation panels (VIPs) by our partner va-Q-tec. Some bioaerogel VIPs will undergo testing by the project partners, and most will be integrated into carbon-reinforced sandwich elements. With this, we want to demonstrate one of the slimmest wall designs possible while using bio-based superinsulation!

3️⃣ The cellulose bioaerogel is also relevant for bioaerogel VIPs in new, more lightweight logistics solutions as well as greener cooling appliances (replacing for example fumed silica).

4️⃣ Based on the learnings he made, Alberto could validate and further improve his process concepts and equipment designs. This is highly important for scaling to our first large production plant. What is most amazing: Almost all of his designs work exactly as he planned.

It seems hard to believe that a year ago we could only produce a couple of liters at a time in the lab. Now we have reached a whole different level and have produced cellulose aerogel at pilot scale. We will be able to serve our customers with much needed pilot-scale quantities for their testing and showcases.

Meeting for CO2-optimized Construction for Roads and Paved Surfaces at DBU

Recently, Marc presented our aerogel-it activities and products at the meeting for CO2-optimized construction for roads and paved surfaces (CO2-optimiertes Bauen von Verkehrsflächen & Straßen). The meeting took place at the DBU Deutsche Bundesstiftung Umwelt Umwelt in Osnabrück.

Michael Hafemann and Mark Gieseke of Gieseke Gruppe expertly moderated the event after Prof. Markus Große-Ophoff of DBU, Mark Gieseke and Prof. Dr. Prof. Dr. Heiko Meinen of Hochschule Osnabrück had kicked it off. The speakers highlighted roads and paved surfaces as very important but often overlooked lever for CO2 savings. Next to buildings they make up a large share of the built environment and cause corresponding CO2 emissions during construction and repair.

There were excellent presentations on decarbonization e.g. of bitumen and concrete by B2SQUARE and CarStorCon® Technologies. Stephan Harnischfeger of MHI Baustoff GmbH explained the challenges around asphalt emissions and low-temperature asphalt products as important solutions. ecopals, ecoLocked, HeideHanf and Bundesanstalt für Materialforschung und -prüfung also gave presentations. Furthermore, there were keynotes by Dr. Martins Zaumanis of EMPA and Prof. Dr. Hans-Hermann Weßelborg of FH Münster.

Aerogels also play a role for CO2-optimized construction in this field and are already being investigated for more thermal-resistant roads and paved surfaces. One example are our US colleagues from aerogel Coating Technologies (aCT Inc.).

Great discussions in the networking sessions rounded off the event. As former DBU Green Startup, we were certainly happy and thankful to have this opportunity to be back at DBU. Thank you very much to the organizers for inviting us.

New team member Eduard Siemens

We are very happy to share that the aerogel-it team has grown: As of January 2025, Eduard Siemens joined our team as new team member and Sales Director.

In addition to being a Sales expert, Eduard is an experienced founder himself. He built a highly successful 3D-printing company, EWOQE, from scratch. With his business running stably, he was looking for new challenges to pursue and found our work and mission. He was intrigued by our aerogel materials and potential they offer. Because of that, he contacted us to see if we could work together – which we immediately accepted.

It goes without saying that his founders experience and Sales skills are invaluable to us. In his first two months, Eduard has already managed to open up lots of exciting opportunities. We are honored to have him on the team!

aerogel-it participates in BIOVIPWALL project

The aerogel-it team is very happy to be part of the BIOVIPWALL open call project funded by iClimabuilt, an EC Horizon Europe project.

Prefab sandwich wall elements are interesting for both new construction as well as for serial renovation of existing buildings as they can be mass-produced in factories. This enables leveraging standardization and automatization for higher efficiency compared to local construction on the construction site.

But currently, almost exclusively steel-reinforced concrete is used which requires minimum thickness to protect the steel reinforcement from corrosion and structural failure over time. The additional concrete for protection of the steel reinforcement leads to additional CO2 emissions during production and transportation.

When using carbon-reinforced concrete (carbon concrete) instead of conventional steel-reinforced concrete, the carbon reinforcement no longer needs to be protected against corrosion. Therefore, the concrete layer can be reduced in thickness which saves material and transport cost, reducing CO2 footprint and reducing CO2 emissions for transportation. Thinner carbon concrete elements also save valuable space in buildings.

Then thermal insulation is required for the envelope, and vacuum insulation panels (VIPs) are the highest-performing thermal insulation materials. When combined with VIPs, carbon concrete wall construction gives access to slimmest wall designs: The overall wall thickness can be reduced from ca. 40 cm to ca. 20 cm or less – or by 50% or more!

Within the BIOVIPWALL project, together with our partner va-Q-tec and the iClimabuilt service providers we will develop and test a new prefab sandwich wall system based on carbon concrete in combination with bioaerogel VIPs such as our cellulose bioaerogel. We will prepare various materials and sandwich elements for test campaigns by iClimabuilt members as well as for demonstration purposes including integration and monitoring in a building. Based on our own calculations, we expect that a substantial CO2 footprint reduction is possible. Stay tuned!

New brand and mission statement – new website coming

Aerogel the World!

After three intense years of research, innovation, and passion, we are ready for an important step – a new brand and mission statement!

When we founded aerogel-it in 2021, we knew the road ahead would not be easy. Building a deep-tech company with high capital requirements is a challenge. But we were convinced: Aerogel has much wider scope than previously thought. And we were right.

We have not just improved existing aerogel materials with their various drawbacks. We have also created the first bio-based aerogels for applications that were previously unimaginable. Aerogels can be everywhere.

At the same time, we completely reimagined aerogel production. Our goal: to develop the best manufacturing technology — sustainable, efficient, and affordable. In our pilot plant, this vision has become reality.

And this is just the beginning on our journey. We felt this was the right moment to redefine our brand but also to sharpen our mission. In a nutshell, we want to leverage our leading aerogel expertise to provide new solutions for global problems, foremost the climate change and decarbonization – and we are in it for the long run. A huge thank you to our partner Nikias Thörner from BYNIK, who has taken our brand communication to the next level.

Our mission: “Global, active climate protection for everyone, every day.”

And the best part? Our new website will be live in just a few days! Stay tuned— we are excited to have you on this journey with us.

Visit from Beerenberg Advanced Solutions team

Last week the aerogel-it team was thrilled to receive Toni Suomäki, Geir Harris and their colleagues of the new Beerenberg Advanced Solutions team at Hamburg University of Technology. Beerenberg has recently bundled innovative products and solutions such as robotics and aerogels in this global business unit to maximize synergies and push innovative topics.

To kick it off, the team took the Beerenberg colleagues on a deep dive into aerogel technology and highlighted the improvements that the aerogel-it team has achieved over the last years regarding aerogel product and process technology: The team developed completely new aerogel products that address current shortcomings of aerogels but also open up new areas of application. And with the new step-change production tech, much higher efficiency and lower cost are achieved. Over the following days, the team then discussed deeper collaboration regarding the Oryza silica aerogel blanket technology as well as the aerogel-it aerogel particle technology.

Both companies see enormous potential in aerogel materials and the solutions they can provide across a wide range of industries and applications. To name one example: The Oryza silica aerogel products offer excellent, space- and energy-saving performance while achieving highest Fire Class A1 – as certified by a German ETA for the Construction industry. We see this as an important contribution to the much-needed energetic renovation of the European building stock.

The Beerenberg visit was rounded off with a tour of the pilot plant where Alberto demonstrated the worldwide largest quantity of our new biomineral aerogel particles! With this silica/biopolymer hybrid material, we are reinventing silica aerogel technology: excellent aerogel performance with highly improved handling, a great sustainability footprint and what is best – at competitive cost. We are looking forward to sharing more details soon – stay tuned!
