Carbon Upcycling is a waste and carbon utilization company unlocking a new frontier of circular materials. We’re tackling the biggest problems on the planet—like climate change and industrial waste. Applying our novel technology platform, we enable hard-to-decarbonize industry to transform local industrial byproducts and natural materials into superior additives. Our first massive market is concrete, the source of eight percent of global CO2 emissions and growing. Our novel technology reduces the carbon footprint of cement, sequesters carbon, and improves concrete performance. We do this by opening up a new class of locally available, carbon-sequestering cement replacements. With Carbon Upcycling, cement producers can now create a superior product using local industrial byproducts and natural materials and save the planet at the same time.

ConnectDER we craft technology and business solutions for the distributed generation industry. Our flagship product provides plug-and-play grid integration for distributed energy resources (DERs) like solar power, energy storage, and electric vehicles.

Travertine process accelerates the Earth’s natural carbon cycle to precipitate carbonate minerals from carbon dioxide in the air, permanently storing carbon in the solid phase.

At Electrified Thermal, we are working to decarbonize the hottest industries and processes by replacing fossil fuels with renewable heat. Our new technology, the Joule Hive Thermal Battery, converts unreliable solar and wind energy into on-demand heat, stored at temperatures approaching 2000 degrees Celsius. The stored heat can be delivered to industrial furnaces, boilers, or power plants that the Joule Hive is co-located with, enabling a phase-out of fossil fuels across heavy industry by 2050.

Aqua Membranes is revolutionizing RO membrane filtration with its unique printed spacer technology. The Polymer is applied directly to the flat sheet membrane to create a customized raised pattern that replaces conventional extruded mesh feed spacers. Unlike traditional membrane spacers that trap particles and biofilm within the spacer mesh and thereby obstruct flow, the printed dimensional spacers optimize flow patterns and turbulence throughout the membrane element, minimizing the entrapment of particulates and organic fouling. Printed spacer technology also increases permeate flow, improves flux and recovery, minimizes system pressure drop, and extends the operational life of a membrane element. Aqua Membranes' unique technology is perfect for spiral-wound membrane manufacturers eager to improve their product performance and whose customers demand more durable, low maintenance elements that can withstand challenging feed streams. Its technology provides a more open design and reduces fouling. Their technology offers a significant reduction in both Capital and Operating Expense in membrane plant operations.
