Our Story

With concerns for the environment and aspirations to create an energy-efficient future, Phase Change Energy Solutions (PCES) was formed in 2011 to pioneer plant-based, non-toxic, non-corrosive phase change materials that transition from solid-to-gel or solid-to-solid when they absorb and release heat.

This innovative material, BioPCM®, can store large amounts of latent heat at targeted temperatures, ranging from -50°C to 135°C, and provides maximum energy performance with minimal impact on the environment. After perfecting and patenting the technology, US-based manufacturing capabilities were established and the world's first gelled phase change products were introduced commercially.

Today, PCES operates a 130,000 sq. ft. R&D and manufacturing facility in Asheboro, North Carolina. Positioned in one of the nation's most research-rich communities, PCES has become a global leader and a recognized manufacturer of next generation phase change products and thermal storage solutions using its proprietary technology platform, BioPCM®.

BioPCM® products are used to improve whole-building energy efficiency in retail, commercial, hospitality and industrial applications; enable safe transport of sensitive food and pharmaceutical products; and provide enhanced thermal storage capabilities for industrial and commercial processes, among other applications. ​

By continuously pushing the known limits of manufacturing capabilities and dedicated research to develop more efficient materials, PCES is positioned to revolutionize the worldwide thermal storage market.
