Millfield Flow Converter can convert energy from rivers into stable electricity or be used for water supply or wastewater pumping.

MFC can harness energy from rivers with flow speeds ranging from 0.5 to 4 m/s and is easily installed on riverbanks, bridges, dams, barges, poles, or rocks. It operates at a low speed, making it gentle on wildlife and plant life, and it is quiet and environmentally friendly.

MFC uses a compact wing module that is driven by water currents, creating movement that is converted into electricity. The wing module is mounted on a specially designed crane, which is installed on a quay, riverbank, or barge, from where the wing module is submerged in the water.

The project builds on previous work, including two prototype tests in a Flow Tank at Force Technology, as well as a government-supported VIS project with DTU Mechanical Engineering. DTU’s development of two newly published MATLAB scripts and their conclusions have been integrated into MFC's latest design, leading to optimization of wing constructions and efficient solutions.

Key findings from DTU's final report confirm that MFC technology, using one symmetrical wing (Naca 0018) measuring 1.5 x 1 meters in a flow with a speed of 4 m/s, can potentially generate 43 kW before losses (376,680 kWh annually, supplying energy to 94 households).

Millfield Flow Converter is energy self-sufficient, modular, and made from common materials such as steel, aluminum, and fiberglass. We also have ambitions for a circular approach (ISO 14001), using materials like recycled wind turbine blades, aluminum kegs, and plastic bottles.

The entire collapsible structure weighs less than 15 tons and is transported in a standard 40-foot container. As a result, it is easy to transport and can be set up in just one day.
