Description: Rushnu’s on-site chlorine production technology targets decentralized chemical production using low-value waste streams as feedstocks. The process is intended to reduce reliance on centralized chlorine production and transportation by enabling production closer to the point of use.

Description: Sensatek’s computer vision technology converts standard video footage into quantitative motion and vibration data. The system uses image analysis to extract structural vibration frequencies and modes without requiring physical sensors on the structure.

Description: Sentinel Ag’s imagery-based fertigation technology analyzes multispectral crop imagery to estimate plant nitrogen requirements during the growing season. The software converts these measurements into spatially targeted liquid fertilizer prescription maps.

Description: SkyCool Systems’ radiative cooling technology uses optical panels that reflect incoming solar radiation while emitting thermal radiation through the atmosphere’s infrared transmission window. The panels can cool circulating water or other fluids to temperatures below ambient air without mechanical refrigeration.

Description: SKYRE’s electrochemical gas separation and compression technology uses proton-exchange membranes to selectively separate, purify, and compress gases from industrial waste streams. The membrane-based systems operate without mechanical compressors or other moving parts.

Description: SolarMantle’s nanoporous polymer thin-film technology provides passive radiative cooling by reflecting most incoming solar radiation and emitting infrared thermal energy through the atmosphere’s infrared transparency window. The material enables surfaces to cool without electricity or active refrigeration.

Description: Sora Fuel’s synthetic aviation-fuel technology converts air into hydrocarbon fuels suitable for aviation. The process is designed to produce jet fuel without relying on agricultural biomass or other land-intensive feedstocks.

Description: SPAN’s smart electrical panel technology provides circuit-level monitoring and control of residential electricity use. The panels integrate household loads with batteries, electric vehicles, and other energy resources through centralized software and remote controls.

Description: Stalagmite’s electrochemical metal-extraction technology selectively recovers critical metals from acidic mine drainage and industrial wastewater. The process separates and precipitates metals including manganese, cobalt, nickel, and rare-earth elements while treating the contaminated water stream.

Description: Stash Energy’s thermal energy storage technology integrates with conventional heat pumps to store thermal energy during off-peak periods. The system uses stored thermal energy during peak periods to reduce electricity drawn from the grid.
