At CES 2026, BLUETTI, a global leader in portable power stations and home energy storage solutions, will introduce a more sustainable version of its popular Elite series. The new Elite 100 V2 features a housing made with partially bio-based Covestro Bayblend® RE polycarbonate, highlighting how advanced materials can support the transition toward low-carbon portable energy solutions.
Unlike conventional polycarbonate, Bayblend® RE contains 25% bio-based raw materials, attributed through mass balance accounting. According to internal calculations, this material innovation can reduce the CO₂ footprint of the battery housing by more than 20%, without compromising durability or safety. The Elite 100 V2 demonstrates how sustainability and high-performance design can go hand in hand in the rapidly growing portable power market.
Portable power stations have evolved far beyond emergency backup devices and are now essential equipment for camping, RV travel, van life, and outdoor work. For BLUETTI, a key design challenge is ensuring that the product housing matches the long lifespan of its internal components. With over 4,000 charging cycles, equivalent to roughly 10 years of use, the LiFePO₄ battery requires a casing that resists aging, brittleness, UV exposure, and extreme temperatures.
Safety is another critical factor. During operation, the housing material must tolerate heat while maintaining excellent flame-retardant properties. At the same time, BLUETTI continues to prioritize carbon footprint reduction, making material selection a strategic part of its sustainability roadmap.
Covestro’s Bayblend® polycarbonate meets these demanding requirements by offering high impact resistance, even in low-temperature environments, and compliance with UL 94 V-0 flame retardancy standards. The Bayblend® RE grade used in the Elite 100 V2 is produced using renewable feedstocks derived from bio-waste and biological residues through mass balance accounting, while delivering the same mechanical and safety performance as traditional materials.
In addition, Bayblend® RE belongs to Covestro’s CQ (Circular Intelligence) product portfolio, which identifies materials attributed with at least 25% alternative raw materials. This supports circular economy principles while enabling manufacturers to lower emissions across the product lifecycle.
“This collaboration with BLUETTI highlights how innovative engineering plastics can accelerate sustainable development in the portable power sector,” said Lily Wang, Global President of Engineering Plastics at Covestro. “Our materials not only meet the technical demands of outdoor energy applications, but also help reduce environmental impact and advance circular economy goals.”
Allen Huang, Vice President of BLUETTI, emphasized the shared vision behind the partnership: “By integrating Covestro’s advanced bio-circular materials, we are enhancing product durability and safety while actively lowering our carbon footprint. This collaboration allows us to deliver reliable, stylish, and more sustainable power solutions to users worldwide.”
Beyond performance and sustainability, Bayblend® also enables refined surface textures and a wide range of color options through Covestro’s CMF (Color, Material, and Finish) expertise, giving BLUETTI greater design flexibility to meet evolving consumer expectations.
