Minesto has developed a technology that generates electricity from predictable tidal currents which is similar to a kite flying in the wind. Its power plant consists of a wing mounted with a turbine, directly connected to a generator in the nacelle. A control system steers the boat along a predetermined trajectory by moving the rudders and ailerons at the rear of the kite. The wing uses the hydrodynamic lift generated by the underwater current to propel the kite. Thanks to the onboard control system, the kite autonomously steers along a predetermined figure-eight trajectory, moving the turbine through the water at a flow speed several times greater than the actual current. The turbine shaft rotates a generator, which supplies electricity to the grid via a power cable in the tether and a bottom cable to the shore. The concept has already been demonstrated and proven.

Natel Energy develops and produces hydraulic turbines FishSafe that improve fish passage, modernize existing power plants and ensure reliable megawatts of grid power. The company uses computer modeling and scale model testing before integrating turbine into existing hydropower plant. It's collaborating with leading turbine manufacturers to implement its designs in hydropower projects worldwide. FishSafe turbines feature thick, forward-curved blades. They ensure 98-100% fish survival rate when passing through them, minimize wear from sediment, extend service life, save money on blade repairs and increase plant productivity by up to 10% by preventing flow losses in bypasses and pressure losses in fine mesh.

Husk is creating solar microgrids in rural Africa regions (primarily in Nigeria, expanding to the Democratic Republic of the Congo, Zambia, and Madagascar). The company has developed an integrated AI-based platform that goes beyond simply selling electricity to include the sale and financing of energy-efficient appliances, comprehensive solutions for rooftop solar power systems on commercial and industrial properties, and a wide range of low-carbon and climate-resilient energy services, including e-mobility, agro-processing, and cold storage. The company says this approach is gradually becoming more intelligent and automated through the use of artificial intelligence and the Internet of Things.

Blue Energy builds nuclear power plants in shipyards because these facilities allow for the processing of large volumes of steel and the easy delivery of it to the construction site after completion. Unlike many nuclear energy startups, Blue Energy isn't developing a new reactor, but rather reimagining the nuclear plant construction process. By shifting the bulk of specialized construction work to the shipyard, Blue Energy significantly reduces project costs. The reactor itself is built in a factory and delivered to the shipyard by barge. While this limits the total number of sites Blue Energy can develop, it can still use rivers to expand into the US, Europe, Africa, and Asia.

Power Ledger is developing a blockchain-based P2P energy trading platform. The company uses blockchain technology to address pressing issues of grid instability and congestion caused by the integration of renewable energy sources into the grid. Current REC (Recommended Energy Certificate) markets are plagued by unnecessary complexity and data issues. The market lacks transparency, necessitating manual management of all REC procurement processes, including KYC verification, contracting, payments, and settlement. Powerledger's platform offers transparent and cost-effective REC trading solution that benefits all stakeholders in the renewable energy sector.

VEIR develops superconducting power transmission systems for data centers and renewable energy. Its superconducting rack-mounted wire (STAR) technology delivers 5-10 times more power than conventional cables at the same voltage level. These advanced cables operate at significantly higher currents with negligible energy loss compared to both traditional and other advanced conductors. This innovation not only increases efficiency but also minimizes the physical space required to transmit large amounts of power. VEIR uses a simple, open-loop passive nitrogen cooling system, where distributed evaporation delivers 20 times more cooling power per kilogram of liquid nitrogen.

Energy Dome develops a low-cost and efficient system for long-duration electricity storage using liquid CO2. Its CO2 Battery Plus technology aims to improve the efficiency and flexibility of gas-fired power generation by combining energy storage with waste heat recovery. The CO2 Battery technology stores energy by compressing CO2. In the conventional setup, both pressure and heat generated during charging are stored separately: heat in a thermal storage system for later use during discharging.
