Molten salt facility awarded USD 2.5M to restart testing
KTH and IMT Mines Albi students collaborate
As part of the Power2Powder project, students Ellen Turås and Carolina Myrvoll from KTH Royal Institute of Technology, together with Quentin Lannoy, an intern from IMT Mines Albi, have been actively engaged in the experimental development and testing of a particle heat exchanger rig at KTH. This collaboration directly contributes to Work Package 2( WP2): Particle Behavior, Transport, and Handling, which investigates the behaviour of particle suspensions, material erosion, and transport mechanisms in hightemperature environments, as part of the broader development of particle-based Concentrated Solar Power( CSP) systems. At the KTH lab, the student team supported the setup and refinement of an experimental rig designed to test horizontal tubular heat exchangers. They applied
Particle Image Velocimetry( PIV) techniques to analyse particle flow characteristics— a key step toward optimizing particle-based systems for scale-up to MW-level pilot plant operation. Ellen and Carolina, working through their KEX( bachelor thesis) project, contributed to both rig development and experimental procedures. Quentin focused on the software side, enhancing the reliability and integration of the PIV analysis tools. Their combined efforts helped to generate valuable experimental data and improve system performance. According to Dr. Taras Koturbash, researcher at KTH and supervisor in the P2P project, this collaboration highlights how combining local academic programs with international internships fosters technical innovation and enriches experimental research.
Concentrating solar thermal power and nuclear industries may soon have a safe, reliable, radiation-free environment to test components in flowing, molten nitrate salts. The DOE Solar Energy Technologies Office awarded USD 2.5M in funding to Sandia to restart the Molten Salt Test Loop facility at the National Solar Thermal Test Facility. With this funding, Sandia can complete the second phase of the Molten Salt Test Loop Restart project, reopening a test location for researchers and industry partners to study molten salt component systems and salt chemistry compositions. Once in operation, the Molten Salt Test Loop could perform industrial-scale validation and demonstration tests for the concentrating solar power and nuclear industries, contributing to ongoing research in these areas. The facility could also perform contingency scenarios such as rapid shutdown
processes and safety procedures. These types of interactions are critical to improving industry safety by addressing accident scenarios such as heat exchanger failure. The facility could test high-temperature molten salt pumps, pressure transducers, flowmeters, valves, and heat exchangers. In addition to testing concentrating solar power molten salt test components and integrated systems, the facility supports a twopronged process for researching molten salt reactors. Through this process, fundamental science researchers could address thermodynamic challenges that exist with fluoride salts and perform scoping to determine which materials could be used to replace potentially problematic components. The Molten Salt Test Loop operates at temperatures of up to 600 degrees Celsius, as required for many industrial power and process heat systems.
Honeywell acquires Sundyne
Honeywell( HON) has announced the completion of its acquisition of Sundyne from private equity firm Warburg Pincus for USD 2.16bn in an all-cash transaction. The acquisition of Sundyne is expected to be immediately accretive to Honeywell’ s sales growth and segment margins as well as to adjusted EPS in the first full year of ownership. Sundyne’ s deep customer relationships, bestin-class products, and technology will unlock strategic growth potential for Honeywell UOP’ s value chains in refining and petrochemicals, liquefied natural gas( LNG), and clean and renewable fuels. Unified under the Honeywell Forge platform, the combined solution provides
a scalable, full-spectrum approach that positions Honeywell as a leader in the energy transition. The completion of this acquisition follows Honeywell’ s announcement of the planned spinoffs of its Aerospace Technologies and Solstice Advanced Materials businesses, which will result in three publicly listed industry leaders with distinct strategies and growth drivers. Since December 2023, Honeywell has announced a number of strategic actions to drive organic growth and simplify its portfolio, including USD 13.5bn of accretive acquisitions. In addition to Sundyne, these acquisitions include: the Access Solutions business from Carrier Global, Civitanavi Systems, CAES
Systems, the LNG business from Air Products, and Johnson Matthey’ s Catalyst Technologies Business. Honeywell also completed the sale of its Personal Protective Equipment business to Protective Industrial Products last month.
Constellium and Nikon AM collaborate on a new project
Constellium has announced the kick off of a new collaborative project with Nikon Advanced Manufacturing( Nikon AM), America Makes, and a team of industry leaders to expand the use of its Aheadd ® CP1 aluminum alloy for additive manufacturing in defense and aerospace applications. The USD 2.1M project is funded by the Office of the Under Secretary of Defense’ s Manufacturing Technology Office( ODS ManTech) through America
Makes, the National Additive Manufacturing Innovation Institute. This project is led by Nikon AM with the collaboration of ASTM International and 3Degrees, along with guidance from top defense contractors including Lockheed Martin, Northrop Grumman, Honeywell Aerospace Technologies, and others. Constellium’ s Aheadd ® CP1 is a high-performance aluminum alloy designed specifically for additive manufacturing. Its strength, thermal conductivity, and excellent printability— allowing high-speed productivity and stability to avoid post-processing— make it ideal for demanding applications such as heat exchangers and other mission-critical components. The project will generate key material property data through testing on Nikon SLM Solutions’ L-PBF systems. Results will be shared via the Workbench for Additive Materials( WAM) database to support qualification and use by defense and aerospace manufacturers.
