Three Leaders Combine Forces for a Greener Construction Future
In a strategic collaboration that signals a major shift toward sustainable construction, ProLogium Technology, Kyushu Electric Power, and Nakayama Iron Works announced their joint development of advanced solid-state battery modules and zero-emission construction machinery. The partnership highlights how cutting-edge energy storage, power infrastructure, and heavy equipment manufacturing can converge to redefine on-site operations. The initial concept, set to be unveiled at CES 2026, promises to demonstrate how solid-state technology can deliver longer range, faster charging, enhanced safety, and lower total cost of ownership for industrial vehicles and equipment.
Solid-State Battery Module: The Core of Zero-Emission Machinery
At the center of the collaboration is a next-generation solid-state battery module designed for heavy-duty use. Unlike traditional lithium-ion packs, the solid-state design employs a ceramic or glass-ceramic electrolyte that enhances safety, thermal stability, and energy density. This allows construction machinery to operate longer between charges while maintaining performance under demanding site conditions. The partners stress that the module is engineered for rugged environments, with improved vibration resistance and rapid charging capabilities that reduce downtime on busy construction projects.
Synergy Across Industries: Energy, Materials, and Equipment
Kyushu Electric Power brings a deep expertise in power supply reliability and grid-compatible energy solutions, ensuring that a fleet of electric construction machines can be supported by resilient charging infrastructure. Nakayama Iron Works contributes its decades of precision manufacturing know-how, enabling scalable production of robust, field-ready equipment. ProLogium supplies the core solid-state battery technology and integration know-how, creating a seamless interface between energy storage and heavy machinery controls. The collaboration aims to optimize system-level efficiency—reducing emissions, cutting fuel-related costs, and improving on-site safety through quieter operation and more predictable power delivery.
CES 2026: A Glimpse of the New Era
The joint project is scheduled to be featured at CES 2026, where visitors will see a prototype of zero-emission construction machinery powered by a solid-state battery module. Demonstrations are expected to showcase extended operating hours, faster battery replenishment, and a reduction in maintenance needs due to the inherent stability of solid-state chemistry. Industry observers anticipate that this combo of solid-state energy storage, reliable electric grids, and high-precision manufacturing could drive broader adoption of electric construction equipment in sectors like road building, mining, and heavy lifting on construction sites.
Environmental and Economic Implications
The move toward zero-emission machinery aligns with global decarbonization goals and stricter emissions regulations in construction corridors around major markets. Beyond environmental benefits, operators stand to gain from lower fuel costs, quieter work environments, and improved workplace safety with fewer thermal and fire risks associated with conventional lithium-ion systems. Over the long term, the collaboration envisions a scalable platform that can be adapted for a wide range of heavy equipment, potentially spurring new business models such as on-site managed charging fleets and retrofitting programs for existing machines.
What This Means for the Industry
As construction projects grow more complex and sustainability benchmarks tighten, the alliance among ProLogium, Kyushu Electric Power, and Nakayama Iron Works signals a proactive approach to next-generation powertrains. The emphasis on solid-state battery modules indicates a belief that reliability, safety, and energy density can be enhanced without sacrificing performance on demanding job sites. If CES 2026 impressions translate into real-world deployments, the construction industry could see a faster transition to cleaner machinery, supported by robust energy infrastructure and high-precision manufacturing capabilities.
Looking Ahead
Whether the venture will redefine the pace of electrification in construction depends on continued collaboration, testing outcomes, and the readiness of global supply chains to deliver the needed solid-state components at scale. Nonetheless, the alliance between ProLogium, Kyushu Electric Power, and Nakayama Iron Works marks a pivotal step toward a future where heavy machinery operates with zero emissions, sustained by reliable energy storage and advanced industrial engineering.
