Sustainable H2-Future: CEO Matthias Rudloff at CHC Forum Science, Dresden

On the 25th of October 2023, our CEO, Matthias Rudloff, had the honor of representing the business perspective at the CHC Forum Science panel discussion. The key takeaways from the discussion:
1. To advance the growth of the hydrogen economy, we urgently need economically viable business cases for #hydrogen applications.

2. It’s vital for policymakers to establish straightforward and practical regulatory frameworks to support this transition.

3. While fundamental research is essential, #Germany has made significant progress. Our challenge now is fostering companies that turn this research into value for the German economy.

AMBARtec and Envenion cooperate on hydrogen projects in Switzerland

AMBARtec AG and Envenion GmbH, the Swiss consulting company for innovative energy supplies, reaffirm their commitment to the Swiss energy market. The two companies plan to work together to bring AMBARtec's uniquely innovative HyCS technology for large-scale hydrogen storage and transport to Switzerland and neighbouring regions.
AMBARtec and Envenion are looking forward to deploying the innovative HyCS® storage technology in Switzerland and adjacent regions.

Envenion GmbH specializes in climate-friendly, low-emission energy supply solutions for residential, commercial and industrial buildings. The company, based in the greater Zurich area, accompanies its customers on the path to energy self-sufficiency with planning, project management and long-term support for the systems. 

Hannover Messe 2023: Successfully completed

Thank you for joining us at the Hannover Messe on 17-22th April 2023. We had the pleasure of meeting Minister President of Lower Saxony, Stephan Weil, and other dignitaries at our booth. We had an informative and robust discussion about hydrogen-storage and the benefits of our HyCS technology.

First plant for storage of energy and hydrogen based on iron oxide successfully commissioned

DRESDEN/FREIBERG - 15 November 2022 - AMBARtec AG (Dresden), together with the EPC company Umwelt- und Ingenieurtechnik GmbH Dresden (UIT), has commissioned the first plant for the storage and transport of hydrogen based on iron oxide using the Hydrogen Compact Storage (HyCS®) process in the Saxon city of Freiberg.
The companies have implemented the demonstration for a hydrogen storage that is in addition to its compactness extremely efficient and sustainable. The strongly reduced water requirement for hydrogen production, the rapid storage and retrieval as well as the simple permitting procedures make the process very attractive.

Compact storage increases transportability
Compared to today’s storage technologies, AMBARtec’s HyCS process enables a much more compact storage and transport of energy and hydrogen. Up to 3 kWh of energy can be stored in one litre of storage material, whereas lithium-ion batteries currently only achieve 0.3 kWh/litre and liquid hydrogen 2 kWh/litre. The solution jointly implemented by UIT and AMBARtec makes the regional and international transport of H2 significantly easier and more cost-effective. Beyond transport, the HyCS process can contribute to becoming less dependent on supra-regional electricity and gas supplies in times of rising energy prices in combination with photovoltaic systems and/or heat pumps.

Technology with a lot of potential
HyCS technology offers enormous potential for increasing the efficiency of electricity storage compared to known H2-based solutions. Through clever integration with high-temperature electrolysers (SOEC) and fuel cells (SOFC), efficiencies of over 65 percent can be achieved, about twice as high as with established processes.

Constructive and trusting cooperation between the project partners The innovative process was first developed into a very detailed technical concept by AMBARtec AG and then implemented by Umwelt- und Ingenieurtechnik GmbH Dresden. Thanks to the cooperation of the individual specialist departments, the planning details were clarified in a targeted manner and the project was completed on time.

AMBARtec company founders Uwe Pahl and Matthias Rudloff, supported by Umwelt- und Ingenieurtechnik GmbH Dresden, have reached a major milestone: with the commissioning, they have provided technical proof that their process, developed over many years, can also be operated in a real plant. "We have already implemented all the components, control loops and safety systems in this plant that are required in real customer facilities," explains AMBARtec CTO Uwe Pahl. "After completing the test operation, we will systematically scale up the storage facility step by step over the next few months."

UIT Managing Director Lars Braun was also satisfied with the cooperation: "Together we have mastered this challenging project as project partners on an equal footing. Thanks to the constructive and trusting cooperation, we were able to react quickly to changing framework conditions. We are very satisfied with the completed plant in Freiberg. I would like to thank all UIT and AMBARtec employees for their excellent work." Storage with a capacity of 250 kWh can be supplied by AMBARtec AG as early as mid-2023, while storage with 3,000 kWh will be available from the end of 2023. Planning for projects with the HyCS standard module in a 20-feet container with a storage capacity of 20,000 kWh can already be kicked off now.
