Dsider builds an AI-powered Decision Intelligence Platform

US-based startup Dsider provides an AI-driven platform that supports energy transition planning and decarbonization strategies. It also enables low-carbon project development across the hydrogen, ammonia, biofuel, CCUS, and power sectors.

Its technology integrates specialized AI agents, a continuously learning knowledge engine, and no-code analytical tools to turn complex climate, economic, and engineering data into actionable insights. Through real-time forecasting, carbon assessment, economic modeling, and scenario analysis, the software streamlines net zero planning.

Also, it aids organizations in evaluating production pathways, storage strategies, infrastructure investments, and lifecycle emissions with accuracy. Moreover, the platform aligns with resource allocation, regulatory compliance, and climate risk mitigation.

FlameSense offers a Wildfire Prevention Technology

Chilean startup FlameSense develops a smart forest monitoring system that detects wildfire ignition conditions before a fire begins. The technology operates through a distributed network of in-forest sensing pods that analyze terrain, microclimate patterns, and environmental risk factors.

It continuously transmits data to an AI engine trained to identify early indicators of ignition. The system works through a sequence of steps, beginning with AI-based terrain analysis to identify high-risk zones and customized installation across priority areas.

It then configures a pod-to-pod network for reliable communication, while adaptive machine learning continuously improves detection accuracy. Its device network monitors the causes of wildfires rather than the flames themselves to enable faster intervention while remaining fully integrated within the forest environment.

Also, the software provides real-time situational awareness and a dynamic risk map that improves with continuous environmental training.

Carbonetics makes an AI-monitored Carbon Capture Platform

Indian startup Carbonetics develops an AI-enabled carbon capture platform that isolates CO2 from industrial emission streams using a modular, chemisorption-based system designed for point-source decarbonization.

The technology directs purified flue gas through contactor lattices where amine-based capture media selectively bind CO2. Then, the system regenerates the sorbent and outputs high-purity CO2 for storage or utilization.

It continuously monitors operational conditions through CapNet, a deep neural network, and OmniSense, an AI-powered monitoring system that applies computer vision and predictive maintenance to sustain uptime and enhance safety.

The platform reduces capture costs by optimizing absorber-regenerator performance, adjusting process parameters in real time, and scaling efficiently across industrial domains such as power, cement, waste-to-energy, fuels, and metals.

Wespran provides CO2 to Methanol Upcycling

French startup Wespran develops biomimetic biotechnology that captures industrial CO2 and converts it into valuable products through a proprietary enzymatic electrocatalysis system. The technology uses cofactor-free enzymes coated on carbon nanotube electrodes to bind and transform CO2 after flue-gas boosting and pressurization.

The reaction stream then moves through evaporation, distillation, and storage steps to produce green methanol and other chemical intermediates suitable for fuels, materials, and consumer goods.

This integrated platform reduces reliance on fossil-derived feedstocks, enables modular deployment alongside existing industrial plants, and supports continuous improvement through data-driven optimization.

Jooules makes a Sustainable Aquaculture Protein

New Zealand-based startup Jooules produces a high-performance protein ingredient through gaseous fermentation that transforms captured CO2 and green hydrogen into a nutrient-rich single-cell protein for aquaculture.

Its process feeds unmodified bacteria with CO2 from industrial emissions, hydrogen produced using renewable electricity, and trace nutrients inside stainless steel bioreactors. Within these bioreactors, the microbes grow and convert the gas streams into biomass.

The technology uses naturally occurring bacterial strains chosen for rapid growth, full amino acid profiles, and the ability to operate without land, freshwater, or marine inputs.

After fermentation, downstream filtration, purification, and drying produce a consistent protein ingredient enriched with essential lipids and minerals.
