Fusion Stellarator Project Gains Formal Backing On 26 February 2026 Munich‑based Proxima Fusion, the Free State of Bavaria, utility RWE and the Max Planck Institute for Plasma Physics signed a memorandum of understanding to build a commercial stellarator at the former Gundremmingen nuclear site [1]. The roadmap begins with the Alpha demonstration reactor in Garching, targeted for the 2030s and intended to achieve net‑energy gain [1]. Financing will combine roughly 20 % private investment, a matching 20 % Bavarian state contribution pending federal funding, and additional participation from RWE [1]. Germany’s Fusion Action Plan earmarks more than €2 billion for fusion research and pilot projects through 2029, supporting the commercial plant goal for 2040 [1].

Industrial Consortium Assembles for Stellarator Supply Chain Proxima launched the Alpha Alliance, a consortium of over 30 industry partners—including Siemens Energy, Air Liquide and Framatome—to coordinate manufacturing, system integration and material supply for Alpha and later commercial plants [1]. The alliance aims to ensure supply‑chain readiness and accelerate technology transfer from the demo reactor to the Stellaris commercial plant [1]. Unlike tokamak designs such as ITER, the stellarator’s figure‑8 magnetic coils avoid toroidal density imbalances, offering potential continuous‑operation advantages [1].

Poland Commits to Standardized SMR Design On 25 February 2026 GE Vernova Hitachi Nuclear Energy and Orlen Synthos Green Energy signed a generic BWRX‑300 design agreement at the U.S. Department of Energy, witnessed by Deputy Secretary James Danly and Polish Energy Minister Miłosz Motyka [2]. Orlen Synthos Green Energy will fund the detailed design, creating a reference model for future small modular reactor (SMR) projects across Poland [2]. The generic design is promoted as a means to reduce costs, accelerate investment preparation and integrate Polish industry into the global supply chain [2].

Polish SMR Plan Envisions Large Fleet The joint venture OSGE, formed by Synthos Group and PKN Orlen, targets a fleet of 24 BWRX‑300 reactors, with development at three sites and the first unit in Włocławek scheduled for completion by 2032 [2]. Ministers Motyka and Wojciech Wrochna highlighted SMRs as baseload power for energy‑intensive industry, a tool to stabilise electricity prices and a repeatable deployment model that lowers capital expenditures [2]. GE Vernova Hitachi CEO Jason Cooper described the OSGE investment as a pivotal step toward accelerating BWRX‑300 deployment in Poland [2].

Both Projects Reflect Europe’s Push for Low‑Carbon Power The German stellarator initiative and the Polish SMR program each combine public funding with private investment to accelerate commercial nuclear technologies [1][2]. While the stellarator aims for a commercial plant by 2040, the Polish SMR fleet seeks operational units by the early 2030s, together illustrating a coordinated European strategy to diversify clean‑energy sources and strengthen domestic supply chains [1][2].

Timeline

Feb 25, 2026 – Poland signs a generic BWRX‑300 design agreement between GE Vernova Hitachi Nuclear Energy and Orlen Synthos Green Energy, with Deputy U.S. Secretary of Energy James Danly and Polish Energy Minister Miłosz Motyka present; the deal funds a detailed SMR reference design to speed future deployments and cut costs [2].

Feb 25, 2026 – GE Vernova Hitachi CEO Jason Cooper calls the OSGE investment “a pivotal step toward accelerating BWRX‑300 deployment in Poland,” while Ministers Motyka and Wojciech Wrochna stress that standardized SMRs will provide baseload power for energy‑intensive industry, stabilize electricity prices, and create a repeatable deployment model [2].

Feb 26, 2026 – Proxima Fusion, the Free State of Bavaria, RWE and the Max Planck Institute for Plasma Physics sign an MoU to build Europe’s first commercial stellarator at the former Gundremmingen nuclear site, launching a roadmap that begins with the Alpha demonstration reactor in the 2030s [1].

Feb 26, 2026 – The MoU outlines a financing split of roughly 20 % private international capital, a matching 20 % Bavarian state contribution pending federal funding, and additional participation by RWE, establishing a public‑private partnership for the stellarator project [1].

2026 – Proxima’s Alpha Alliance gathers more than 30 industry partners—including Siemens Energy, Air Liquide and Framatome—to coordinate manufacturing, system integration and materials for the Alpha demo and future commercial plants, ensuring supply‑chain readiness [1].

By 2029 – Germany’s Fusion Action Plan earmarks over €2 billion for fusion research, infrastructure and pilot projects, aiming to support the Alpha demo and achieve a commercial stellarator plant by 2040 [1].

2030s – The Alpha stellarator aims to achieve net‑energy gain, becoming the first fusion device to generate more power than it consumes and serving as a testbed for key technologies that will feed into the subsequent Stellaris commercial plant [1].

2032 – The first BWRX‑300 reactor at Włocławek is slated for completion, marking the launch of a planned fleet of 24 small modular reactors across three Polish sites [2].

2040 – The Stellaris commercial stellarator plant is expected to begin continuous baseload power generation, offering an operational advantage over tokamak designs such as ITER by avoiding toroidal coil density imbalances [1].
