Deep Space Energy, SIA

Based in the UK, Deep Space Energy Ltd. specializes in developing advanced radioisotope power systems for deep space exploration, providing reliable energy solutions to enable critical missions. Deep Space Energy Ltd. was founded in 2022 in Coventry, UK, focusing on innovative energy solutions for deep space missions.

The company has successfully completed 2 deals, with the latest deal on February 11, 2026. The most recent funding round raised EUR 350,000, led by Outlast Fund, which is part of a larger EUR 930,000 venture and grant funding initiative. Dr. Mihails Scepanskis founded the firm and leading it as CEO as of 2026.

Deep Space Energy specializes in the development and commercialization of radioisotope power systems (RPS) designed to deliver resilient electric power for deep space exploration and resource utilization. Their core product is a modular 50W power system that converts radioactive heat into electricity with a 25% efficiency rate, significantly reducing the radioisotope fuel required compared to traditional radioisotope thermoelectric generators (RTGs). These systems are designed to operate effectively in extreme conditions, including the harsh darkness of lunar nights and Martian dust storms, thereby supporting critical scientific payloads and enabling continuous power supply for missions. The intended end users include governmental space agencies, such as the European Space Agency, and commercial entities involved in lunar exploration and Martian missions.

The target geographical markets include Europe, particularly through partnerships with ESA, as well as potential clients in North America and other regions involved in space exploration. Deep Space Energy generates revenue primarily through partnerships and contracts with governmental agencies and commercial enterprises requiring reliable power solutions for space missions. The company engages in business transactions that involve providing Power-as-a-Service offerings, allowing clients to access regulated radioisotope power sources under legally compliant frameworks. This transactional structure may include long-term contracts for continuous power supply during missions, ensuring operational capabilities across lunar and Martian environments.

Specific pricing plans for individual products have not been disclosed, but the revenue model likely incorporates a subscription-like framework, facilitating steady income from clients relying on Deep Space Energy's advanced power systems. Deep Space Energy plans to utilize the EUR 350,000 raised in February 2026 to further develop its power generation technology and support its transition toward commercial use for satellite and space applications. The company is working on enhancing its product offerings and aims to expand into new markets, specifically targeting North America and potentially other regions by 2027. This expansion will support their mission to provide reliable energy solutions for future exploratory missions.
