Proxima Fusion signs Japanese partnerships for supply chain
Proxima Fusion, a German fusion power company, has signed Memoranda of Understanding (MoUs) with Japanese firms Fujikura and Kyoto Fusioneering to develop critical technologies and industrial supply chains for commercial fusion power. The agreements, signed in Tokyo during a visit by German Chancellor Friedrich Merz, focus on high-temperature superconducting (HTS) tape manufacturing, plasma heating, and fusion fuel cycle technologies. The partnerships aim to strengthen Germany's industrial base for fusion, with a goal of building the world's first fusion power plant in the country. This includes assessing the feasibility of HTS tape production in Germany and advancing gyrotron and fuel cycle technologies. Proxima plans to build its Alpha demonstrator in the early 2030s and its first commercial plant, Stellaris, later that decade, supported by over 50 industrial partners in the Alpha Alliance.
The partnerships are significant for the fusion energy supply chain, but they are not directly related to AdTech, MarTech, or digital advertising. They may have indirect implications for technology innovation but are outside the core industry focus.

Recent verified developments and strategic activity across this market segment.
Proxima Fusion invests €140M in HTS tape plant
German fusion startup Proxima Fusion announced plans to build a €140 million factory in Lower Saxony to produce high-temperature superconducting (HTS) tape, a critical component for its stellarator reactor design. The facility will reduce reliance on Asian suppliers, which currently dominate HTS tape production. The company will use a mix of public and private funding, with the state government contributing €21 million. Proxima recently raised €411 million, positioning it among top-funded fusion startups. The factory aims to secure supply for its demonstration plant, which requires 20,000 km of tape, and future commercial plants needing double that amount.
German startups expand to Japan: defence, fusion, quantum
The article reports on a wave of German startups expanding to Japan, highlighted during Chancellor Friedrich Merz's visit. Quantum Systems announced MoUs with Mitsubishi Chemical and Panasonic and established a Tokyo subsidiary. Proxima Fusion signed partnerships with Kyoto Fusioneering and Fujikura for fusion technology. OHB and Astroscale agreed to explore orbital services. Previous developments include Helsing's partnership with Rakuten, Panasonic's investment in tado°, QUDORA's subsidiary and partnership with Fixstars, and DeepL's Japanese subsidiary. Motivations include access to manufacturing expertise and Japan's startup investment plan. Challenges include language and business culture.
Race to Power the Grid by 2035 Widens
Tech companies' growing AI compute needs are driving investment and commercial deals across fusion, small modular fission, natural gas, and long-duration battery storage as contenders to supply reliable 24/7 power by 2035. Natural gas remains the current baseload choice but faces supply-chain vulnerabilities and multi-year turbine backlogs. Several small modular reactor (SMR) firms and fusion startups aim to connect commercial plants to grids in the early 2030s; notable projects include Kairos Power's Hermes 2 demo, Oklo's 2028 target, Commonwealth Fusion Systems' demo and 400 MW Arc, and Helion's aggressive plan to deliver electricity to Microsoft by 2028 and to supply OpenAI at multi-gigawatt scale by 2030–2035. Cost and scale remain key hurdles: current levelized costs for new nuclear and fusion are high versus gas and renewables paired with batteries, while new long-duration storage (iron‑air, organic fluid designs) could undercut alternatives.
