Zeam is the world's first autonomous and electric urban passenger ferry. The concept is to deploy a network of small uncrewed vessels that connect city districts across urban waterways. Zeam is a low-cost, flexible, emission-free, and compelling alternative to driving around or building new bridges. Autonomy is the enabler, and the market opportunities are enormous worldwide.
Project TRL: TRL 8 - Actual system completed through test and demonstration
Main sector: Shipping & ports
Zeefier® develops and supplies industrial 100% seaweed-based dyes for textile production. Based in Amsterdam, our team works with leading partners across Europe to provide a scalable, sustainable alternative to synthetic dyes. Our dyes are designed for performance, made for industry, and built to support environmental responsibility at scale.
By turning seaweed (a renewable and abundant resource) into high-quality textile dyes, we combine innovation, functionality, and sustainability . Our dyes integrate directly into existing industrial systems, requiring no process changes or additional equipment.
Project TRL: TRL 7 - System prototype demonstration in a relevant environment
Main sector: Blue biotechnology
Zenco's core innovation is the Zenethane™ feedstock pellet — a proprietary seaweed-blended formulation engineered with anaerobic digestion additives at the cultivation stage. Unlike conventional AD feedstocks, the pellet is pre-optimised for maximum biogas yield before it reaches the plant, eliminating pre-treatment costs and yield variability for operators.
The pellet is produced during offshore seaweed cultivation, structured as a natural capital project: ocean bioremediation and CO₂ drawdown are the primary purpose; feedstock supply is the commercial consequence.
The pellet drives three commercial outputs from a single process: Zenethane™ (certified biomethane, ISCC EU certifiable, GGCS-registered), Zenthilizer™ (premium bio-fertiliser from the high K, N and P content of seaweed digestate), and in Phase 2, Zenthynol™ (drop-in SAF, diesel and LPG via Fischer-Tropsch synthesis). The pellet is also licensable to third-party AD operators as a standalone recurring revenue stream.
Project TRL: TRL 5 - Component validation in relevant environment
Main sector: Blue renewable energy
ZENI (ZEro NItrate) is a nature-based solution start-up, that has developed an innovative solution for wastewater treatment using microalgae. This sustainable method effectively cleans industrial waters, removing pollutants such as nitrates and phosphates, and also preserves natural resources.
The process is circular :
- The purified water can be reused in various applications, such as industrial processes and agricultural irrigation.
- the process also generates a valuable byproduct—algal biomass, that can be valorized as biofertilizer in agriculture and as a product in the animal feed industry.

Project TRL: TRL 9 - Actual system proven through successful mission operations
Main sector: Shipping & ports
Zeroqu is a web-based platform that combines our proprietary Fouling Exposure Index (FEI) — built from AIS voyage tracking and paint-specific degradation, life cycle, and idle impact models — with a physics-based hull performance model calibrated to each vessel's own design and trial data. The platform continuously monitors speed % and power deviation % against this ship-specific baseline, factoring in real hull husbandry events like cleaning, dry-docking, and propeller polishing. Vessel and shore teams get live visibility into hull condition and compliance scores such as CII, plus early alerts when performance starts to degrade.
