Abstract

In the 26th Conference of the Parties (COP26), United Nations Framework Convention is committed to suppressing the acceleration of climate change due to carbon by applying energy from fossil fuels to New Renewable Energy (NRE). Indonesia targets that in 2060 the coal phase-out will be replaced by renewable energy 2056. As a tropical country with many rivers and many lakes, Indonesia has a water energy potential of 75,000 MW. In some remote areas, the need for electrical power is pico scaled (< 5kW). The vortex turbine was chosen to be suitable for river flow with low water levels, low maintenance and construction costs, as well as being environmentally friendly for the underwater ecosystem. This study aims to compare the performance of the vortex to the differences in the shape of the pico scale blade. This study was carried out with variations in the shape of the straight, tilted, and curved blades. Based on the results of all vortex turbine studies, it can be ascertained that the best blade shape obtained numerically is an inclined blade with a hydraulic efficiency of 36%.
