Mikrohes produces Archimedes Screws Turbines (ASTs). ASTs are a new form of small, hydroelectric powerplant that can be applied even in low head sites. ASTs offer a clean and renewable source of energy and are safe for wildlife , especially fish in hydro generation options. ASTs can offer many economic, social and environmental advantages that make them an important option for providing sustainable hydropower development.

Archimedes screws can operate in low water heads (less than about 10 m) and a wide range of flow rates with practical efficiencies of 60% to 80% and can generate up to 400 kW of power. ASTs increase the number of suitable sites where it is possible to develop sustainable hydropower, including undeveloped, hard to access regions and small communities. At many low head sites, ASTs may be more cost-effective, with lower installation and operating costs than alternative hydropower systems. ASTs may also reduce the disturbance of natural sedimentation and erosion processes, and have smaller impacts on fish and other fauna. ASTs can often be retrofitted to existing unpowered dams or weirs, providing new hydropower capacity for very little marginal environmental impact.

Gemasan Robotics is a robotics company developing autonomous underwater systems for marine maintenance, inspection and monitoring applications. The company’s work focuses on improving the efficiency, safety and sustainability of operations in maritime and underwater infrastructure environments. Gemasan Robotics’ technology is a modular autonomous underwater robot designed to clean biofouling and pollution from the submerged surfaces of ships, reducing hydrodynamic resistance and associated fuel consumption. The system enables in-water hull maintenance without the need for dry-docking and can be operated wirelessly or via cable, depending on operational requirements. It integrates AI-based image processing and thickness measurement software to support real-time diagnostics, hull mapping and condition assessment. Beyond maritime vessel maintenance, the robot is applicable to the inspection and cleaning of underwater infrastructure such as dams, hydroelectric power plants, ports and research installations. Its modular architecture allows configuration for additional use cases, including leak detection, sediment analysis and underwater habitat mapping. The company also provides simulation tools to support operator training and deployment planning, and is developing in-house production capabilities for key components to enhance system reliability and adaptability.

ALGBIO treats wastewater sewage and captures CO2 with microalgae to produce biofuels, bioplastics, biomaterials and generate carbon credits. Algae are desirable as a source of biofuel as they have a high yield of oil and can flourish on land where other plants can not be produced. As plants, algae can grow with carbon dioxide, sunlight, and nutrients. ALGBIO harvests biomass and turns it into gasoline or black coal, which can be sent to refineries to be converted into chemical or transport fuel. With adequate research and development, biofuel, bioplastic and biomaterials from algae could be a price-effective alternative for petroleum based options.

ALGBIO’s circular economy model provides zero waste policy by maximizing resource utilization and minimizing waste with bioplastic production from algal waste too. ALGBIO enables the transition from a fossil based economy to sustainable manufacturing by providing waste management, carbon capture and renewables.
