Dynastrom

Dynastrom ApS, founded in 2021 by Tue Physically and Lasse Vinther, operates within the sustainable energy sector, focusing on the development of cost-effective and scalable energy storage solutions. The company's core mission is to facilitate the transition to renewable energy sources by addressing the intermittency of power generation from wind and solar. The founding team brings together relevant expertise for this venture. Tue Physically has a background as a researcher at the Technical University of Denmark (DTU), specializing in Power-to-X technologies and electrochemistry, which directly informs the company's technological foundation. Lasse Vinther complements this with experience in business development and project management, crucial for navigating the commercial landscape of the energy industry.

The business centers on a proprietary all-iron redox flow battery technology. This approach distinguishes itself from conventional battery chemistries, such as lithium-ion or vanadium flow batteries, by utilizing abundant and low-cost materials, specifically iron, water, and salt. This choice of materials aims to significantly lower the levelized cost of storage (LCOS), a key metric for the economic viability of large-scale energy storage projects. The target market includes utility companies and other large-scale energy producers and consumers who require long-duration energy storage to balance the grid and maximize the use of renewable assets. Dynastrom's revenue model will likely be based on the sale of these battery systems and potentially long-term service and maintenance contracts.

The product itself is a modular battery system designed for scalability, allowing it to be tailored for various project sizes, from kilowatt-hour to megawatt-hour capacities. A key feature is the decoupling of power and energy capacity; energy is stored in the electrolyte liquid, while power is determined by the size of the electrode stack. This modularity provides flexibility for clients to optimize their energy storage installations based on specific needs. By using non-flammable, water-based electrolytes, the system also offers a higher safety profile compared to some other battery technologies. The company has received support from institutions like the EIT (European Institute of Innovation and Technology) and has participated in accelerator programs such as GreenUP Accelerator and Venture Lab by The Danish Foundation for Entrepreneurship, indicating external validation of its technology and business plan.
