Dynelectro, a pioneering company in sustainable energy solutions, announces its first commercial-scale Dynamic Electrolyser Unit (DEU), after exceeding two years performance testing with low degradation.
Demonstration of the first dynamic electrolysis unit reaches initial investment decision at European Energy’s green methanol facility in Denmark:
- FID reached to develop and deploy the commercial-scale fully modular 1-MW Dynamic Electrolyser Unit (DEU) at European Energy’s Danish renewable energy facility.
- Technology maturation funding reaches €20m, with nearly 50% from innovation funds.
- Performance testing exceeds two years and shows very low degradation rates of 3µΩcm2/hour.
About Dynelectro
Founded in 2018, Dynelectro is at the forefront of developing advanced, sustainable energy solutions. Utilising cutting-edge solid-oxide electrolysis technology, Dynelectro achieves unprecedented system performance and lifespan. Co-founders Søren Højgaard Jensen and Samantha Phillips bring more than 50 years of combined experience, respectively, within high-temperature electrolysis and resource deployment focused on innovation and technology.
Their innovations enable operators to seamlessly adjust production based on the availability of cost-effective renewable energy. The company commercialises MW-scale Dynamic Electrolyser Units (DEUs), delivering clean hydrogen to unlock syngas and e-fuel production.
Dynelectro green hydrogen technology
Dynelectro’s technology focuses on next-generation solid-oxide electrolysis (SOE) and offers unparalleled system performance and longevity. SOE aids decarbonisation in hard-to-abate sectors by efficiently producing hydrogen and utilising industrial waste heat. It supports heavy industries and chemical production by providing on-site hydrogen, reducing emissions, generating synthetic fuels, and enabling the green energy transition in these sectors. SOE is poised to revolutionise the energy sector by enhancing energy efficiency, reducing costs, and facilitating broader renewable integration.
Dynelectro’s journey, thus far, has culminated in over €20m, which has been solely directed to technology and innovation development. Comprised of €11m in equity funding with early-stage investors, including Export & Import Fund of Denmark (EIFO), Yara Growth Ventures, Vsquared Ventures, PSV Deeptech, The Footprint Firm and the European Innovation Council (EIC) Fund. Furthermore, €9m in grant funding has been achieved from the European Innovation Council, Shell Gamechanger, the Danish Energy Technology Development and Demonstration Program (EUDP) and other innovation programmes.
According to the European Innovation Council technical evaluation: “The technology may significantly transform and strongly accelerate a major new market. It, therefore, justifies a breakthrough characterisation. It supports the adoption of hydrogen as a major clean energy carrier and strongly contributes to the EU’s Green Deal.” The European Investment Bank’s involvement in this round marks a step change in our maturity, transitioning our investor profile toward industrial investors.
Performance testing
After surpassing 16,000 hours of operation, the performance has shown a degradation of less than 3µΩ · cm² per hour, with downtime remaining below 2%. The load factor has consistently exceeded 92%, even with 6% of the time allocated for standby during performance measurements. It’s worth noting that the typical degradation rate for alkaline systems falls within the range of 2-5µΩ · cm² per hour, highlighting the efficiency and stability of the system in comparison, as seen in the following image.
Benefit of SOE
Current electrolysis technologies waste 25-50% of input electricity, limiting their commercial and sustainability potential. Solid oxide electrolysis (SOE) offers the highest conversion efficiency but has been hindered by its short lifespan, making it cost-prohibitive. Dynelectro’s innovative AC:DC technology addresses this issue, extending SOE lifespan from two years to ten years, thereby aligning it with other electrolyser technologies. This advancement reduces costs and enables quick production adjustments, aiding in grid balancing through ancillary services. Consequently, Dynelectro becomes a crucial partner for Power-to-X developers striving to lower green hydrogen costs.
The completion of the first 1-MW unit installation at European Energy’s renewable energy facility in Denmark is scheduled for the first half of 2025, demonstrating the practical applications and benefits of this advanced energy solution.
