Energy Storage
& Capture

Reducing energy and cost requirements

Nanoparticles can be used in a large variety of applications in energy storage and sorbent materials, including gas capture and storage, photovoltaics, batteries, fuel cells and catalysts. New applications are constantly being developed, and Promethean Particles offers materials to move these applications forward.

Metal oxides are used in energy storage applications, such as fuel cells and batteries. Metal organic frameworks (MOFs) can absorb gas and other materials. Small particle size and higher specific surface area allow for milder processing conditions, such as lower sintering temperatures. In turn, this can help reduce energy requirements and the associated costs during downstream processing. Costs previously limited the application of MOFs, but Promethean Particles’ large-scale continuous production is positively impacting the market and enabling advances.

Metal Organic Frameworks

• Coordination compounds composed of metal ions or clusters that are linked by rigid organic linker molecules to form 2D or 3D porous structures
• Void space can be used to absorb/store gases, such as H₂, CO₂, SO₂ and N₂
