XFuel develops a single-step Chemical Liquid Refining (CLR – CLEAR) process that converts waste hydrocarbon liquids into ultra-clean, drop-in transport fuels aimed at the shipping sector and other hard-to-abate industries. The company is building a modular production plant in Catalonia designed to process 16,000 tonnes of marine waste oils into 14,000 tonnes of low-carbon marine gas oil using waste-based feedstocks. XFuel says the waste-derived feedstocks and process will significantly reduce the carbon footprint of produced fuels. The Catalonia facility is intended as a flagship demonstration of commercial viability and infrastructure compatibility for drop-in low-carbon fuels. The company secured a €4.1 million competitive grant—the second-largest award under the programme—to support the project, which company leadership frames as validation of its technology and commercial credibility. The project also aims to contribute to local economic regeneration in communities facing nuclear plant closures.

Neptune Robotics is a Hong Kong–based technology company that develops and deploys autonomous underwater robots for hull cleaning, aiming to eliminate the need for human divers. Its robotic systems are capable of working up to five times faster than divers while tolerating strong currents and low-visibility conditions. The company’s fleet currently services major bulk carrier and container ships across 61 ports in Asia. By keeping hulls free of biofouling, Neptune helps ship operators cut fuel consumption, reduce emissions, and lower operational risk. The firm plans to channel new capital into R&D for additional robotic platforms and AI-enabled service systems. Expansion into new global markets—beginning with Japan—is a key priority. The strategic relationship with NYK Line reinforces the maritime industry’s interest in technology that improves efficiency and sustainability.
