Technology group Wärtsilä has successfully completed large-scale testing of its proprietary Active Ignition Mitigation System (AIMS). AIMS is engineered to mitigate potential flammable gas build-up during an abnormal thermal scenario within battery energy storage systems (BESS). With this milestone, Wärtsilä becomes one of the first BESS integrators to demonstrate the effectiveness of an integrated explosion control system.
In July, Wärtsilä conducted a series of three rigorous full-system tests in the United States. Each test simulated worst-case thermal runaway scenarios within Wärtsilä’s Quantum2 containerised BESS enclosure. During the tests, a flammable gas blend, representative of UL 9540A CATL 306Ah cell-level testing, was released at multiple internal locations over a two-minute period. The tests were witnessed by a major US-based utility, a fire alarm vendor, and a third-party consultant. Across all three tests, AIMS successfully prevented uncontrolled deflagrations and structural deformations, allowing the Quantum2 system to remain fully intact with no compromise to enclosure integrity. The tests validated the system’s ability to maintain safety and functionality under extreme conditions.
“AIMS is more than just a technical upgrade – it represents a paradigm shift in energy storage safety,” said Mishaal SyedNaveed, Product Manager, Fire Protection at Wärtsilä Energy Storage. “We believe true safety starts well before gases build up as a result of thermal runaway. With AIMS, we are pioneering technology to help our customers manage BESS risks before they escalate.”
Advancing beyond reactive containment, Wärtsilä’s AIMS technology takes a pioneering approach by deliberately igniting flammable gases before they accumulate. AIMS uses sparker systems in combination with door-mounted deflagration panels to safely ignite flammable gases at the earliest stage of a thermal event. This early intervention prevents significant off-gas build-up and reduces the likelihood of deflagration panel activation.
“This test is a first-of-its-kind in the industry, and a powerful testament to the leadership of our fire safety experts,” said Tamara De Gruyter, President of Wärtsilä Energy Storage and Executive Vice President at Wärtsilä. “We’re not only rethinking how storage systems are built, we’re also actively collaborating with first responders, emergency personnel, customers, consultants, and other stakeholders to engineer a robust system and best equip our partners to act when it matters most.”
During the testing, Wärtsilä collected visual, temperature, static and dynamic pressure, and UV/IR data, which will be used to continue the company’s commitment to energy storage innovation and community safety. These rigorous tests and industry-leading safety investments align with Wärtsilä’s ongoing effort to not only meet, but exceed, evolving safety and regulatory standards. The company partners with its customers to offer integrated support across its products and lifecycles to ensure full compliance across global markets.

Boeing [NYSE: BA] unveiled a 3D‑printed solar array substrate approach that compresses composite build times by up to six months on a typical solar array wing program from print to final assembly. This represents a production improvement of up to 50% when compared to current cycle times.
Flight‑representative hardware has completed engineering testing and is progressing through Boeing's standard qualification path ahead of customer missions.
"Power sets the pace of a mission. We reached across our enterprise to introduce efficiencies and novel technologies to set a more rapid pace," said Michelle Parker, vice president of Boeing Space Mission Systems. "By integrating Boeing's additive manufacturing expertise with Spectrolab's high‑efficiency solar tech and Millennium's high‑rate production line, our Space Mission Systems team is turning production speed into a capability, helping customers field resilient constellations faster."
The first 3D-printed solar arrays will fly Spectrolab solar cells aboard small satellites built by Millennium Space Systems. Both non-integrated subsidiaries are part of Boeing's Space Mission Systems organization.
Beyond the arrays themselves, Boeing's approach enables a parallel build of the complete array, pairing a printed, rigid substrate with flight-proven modular solar technologies.
By printing features such as harness paths and attachment points directly into each panel, the design replaces dozens of separate parts, long‑lead tooling, and delicate bonding steps with one strong, precise piece that is faster to build and easier to integrate. It is built upon the foundation of Boeing's qualified additive, flight-proven materials and processes.
"As we scale additive manufacturing across Boeing, we're not just taking time and cost out, we're putting performance in," said Melissa Orme, vice president, Materials & Structures, Boeing Technology Innovation. "By pairing qualified materials with a common digital thread and high‑rate production, we can lighten structures, craft novel designs, and repeat success across programs. That's the point of enterprise additive, it delivers better parts today and the capacity to build many more of them tomorrow."
Across the Boeing portfolio, the company has incorporated more than 150,000 3D‑printed parts, yielding significant schedule, cost, and performance benefits. This includes more than 1,000 radio-frequency parts on each Wideband Global SATCOM (WGS) satellite currently in production and multiple small‑satellite product lines with fully 3D‑printed structures.
The new array approach is designed to scale from small satellites to larger platforms, including Boeing 702‑class spacecraft, targeting market availability for 2026.
By printing the panel's structure and built‑in features, Boeing can assemble the array in parallel with cell production. Robot‑assisted assembly and automated inspection at Spectrolab further reduce handoffs, improving speed and consistency.

Sol Systems, an independent power producer (IPP) committed to building, owning, and operating domestic clean energy infrastructure that benefits local communities, announced that Great Bay Renewables (GBR) has made an initial commitment of approximately $80 million in interconnection letters of credit (LCs) supporting Sol's MISO portfolio. The revolving facility will be used to post refundable milestone deposits to MISO and, subsequently, to support readiness deposits in PJM.
"Interconnection is a bottleneck for U.S. clean energy deployment," said Richard Romero, Chief Financial Officer, Sol Systems. "This facility lets us scale more efficiently by posting deposits with letters of credit rather than cash, so we can advance a broader, de-risked portfolio for our customers and capital partners. Great Bay Renewables understands today's queue realities and structured a solution that meets the moment."
Frank Getman, CEO of Great Bay Renewables, said, "The capital required for grid interconnection security is one of the largest impediments to energy project development. At Great Bay, we specialize in creating innovative financial solutions to solve these complex problems. Our interconnection financing frees up our partners' balance sheets, enabling companies like Sol Systems to deploy their resources efficiently to build the projects that accelerate the growth of American industry."
Non-cash-collateralized LC capacity has historically been reserved for large, credit-rated platforms. By partnering with GBR, Sol gains balance-sheet efficiency comparable to the industry's largest players while continuing to invest in rigorous upfront engineering and site selectivity. This non-cash-collateralized LC capacity enables Sol to advance a greater number of high-quality interconnection positions without tying up cash, supporting a larger, more diversified pipeline and accelerating deployment as projects mature.
