AMBARtec is exhibiting at the 1st East German Hydrogen Congress

 

On 26 August 2026, the European Metropolitan Region Central Germany and the HYPOS hydrogen network are inviting participants to the 1st East German Hydrogen Congress in Dresden. Please note that the congress will be held in German.

As part of the accompanying trade exhibition, AMBARtec will present its compact, safe, iron-oxide-based hydrogen storage systems, which are compatible with standard logistics.

Our exhibition focuses on two key topics:

Seamless hydrogen supply with silver recycled hydrogen

For sites without a pipeline connection, AMBARtec offers container-based hydrogen delivery using standard logistics (truck, rail, ship) – 25–50 % cheaper than conventional storage. We also offer cost-effective silver hydrogen. Unused hydrogen from exhaust and residual streams of industrial processes is captured, processed and returned for reuse. This is recognised as ‘low-carbon hydrogen’ under EU Delegated Regulation C(2025) 4674.

Heat supply via hydrogen during the cold, dark doldrums

Our storage systems enable municipal utilities, energy suppliers and the housing industry to provide heat and power on demand, even during periods of low renewable electricity generation. Installed in standardised 20-foot containers, the solution is easy to transport and install, and integrates seamlessly into existing boiler and CHP systems without the need for costly conversions.

Safe, efficient and straightforward: intercontinental hydrogen transport


Find out more at the AMBARtec stand at the World Hydrogen Exhibition

Rotterdam, 20–21 May, Hall 4 / Stand B110b

Hydrogen is a forward-looking energy source, particularly attractive due to its excellent storage capacity. The challenge: How can it be transported safely and cost-effectively over long distances? For example, from sun-drenched desert regions to energy-intensive economic hubs?

AMBARtec presents the solution: iron nuggets as storage medium. When loaded, the systems contain only iron, so hydrogen cannot escape. This eliminates the need for expensive safety measures or complex infrastructure work in ports, and ships do not need to be retrofitted.

The storage systems can be easily transported using conventional logistics methods, such as by crane, ship, lorry or rail. They are readily available, technically mature and cost-effective.

To find out more, visit us at the World Hydrogen Exhibition in Rotterdam: German Pavilion, Hall 4 /Stand B110b.

Ramp-up of hydrogen economy picks up speed despite complex regulatory framework

Handelsblatt hydrogen summit: AMBARtec CEO Matthias Rudloff as expert on the podium

The hydrogen industry faces numerous challenges. On the one hand, some regulatory requirements are hindering the realisation of hydrogen projects. These include a lack of technological openness in hydrogen production, overly complex rules for defining climate-friendly hydrogen, and delayed government investment and subsidies.

On the other hand, companies need to improve the economic efficiency of hydrogen as an energy source. Matthias Rudloff, a participant in one of the panel discussions, shares this view based on his experience in his day-to-day work at AMBARtec. However, he also recognises the opportunities arising from technological developments in the use of hydrogen for energy storage. "Numerous discussions and comments have confirmed that hydrogen still has great potential to make our future energy supply both sustainable and secure. However, it is imperative to encourage companies to plan for security and drive innovation forward," he concluded.


Matthias Rudloff was also in high demand as a discussion partner outside of the conference programme, particularly among steel industry representatives. After all, the AMBARtec process enables blast furnace or coke oven gas from steelworks to be converted into clean hydrogen by capturing CO₂.

Regardless of the hydrogen source, the AMBARtec process enables hydrogen to be stored and transported without changing the infrastructure and at competitive costs. AMBARtec has also launched an initiative to provide the economy with cost-effective hydrogen produced in various industrial processes that cannot currently be used.

Industrial-scale production of containers and storage tanks  
 
AMBARtec plans to sell several hundred of its 20-foot standard storage containers per year from 2028. Each contains 10 tanks for the iron nuggets, which can carry the equivalent of up to 800 kg of hydrogen.  
 
The tank design has to meet several criteria: it has to create optimal conditions for the processes involved in storing and withdrawing the hydrogen, the dimensions and weight have to meet the transport requirements, and the tanks have to be economical to produce. "To achieve this, we need a partner with extensive practical expertise, particularly in automated welding and industrial series production in general," explains Uwe Pahl, Technical Director of AMBARtec. "Purem by Eberspächer has exactly this knowledge and already works with the same steel grades that we use for the tanks. The company is also able to set up a production line within a relatively short period of time."  
 
"We see great potential for a future technology in the cooperation with AMBARtec: thanks to our expertise in the field of hydrogen materials science and our industrialisation know-how, we are adding great value to the development of new storage and transport options for this energy source," explains Benjamin Brenkel, Executive Vice President Business Unit Europe.   
 
Cooperation with Purem by Eberspächer in pilot phase  
 
AMBARtec is currently optimising and testing the prototype of its 800 kg storage tank. Matthias Rudloff, CEO of AMBARtec AG: "Purem by Eberspächer is now helping us to gain insights from the pilot phase for subsequent series production and to contribute its knowledge to product optimisation – with the aim of manufacturing the product as economically as possible."   
 
Preparations for series production are being made in a joint project with the TU Bergakademie Freiberg. The Free State of Saxony and the EU are funding this project with around €4 million EUR from the 'Joint R&D Project Funding 2021–2027' programme. As a result, Europe's first hydrogen storage power plant will be built in Freiberg by early 2026.
