The manufacturing process described pertains to the production of blade hubs for 1.5 MW wind turbines. These hubs are integral components of wind turbines, designed to connect the blades to the rotor. Hubs of this nature are specifically used in the construction of wind turbines for generating renewable energy. Wind farms, such as the one referenced with 33 domestic turbines in Inner Mongolia, rely on these hubs for their wind power installations, contributing to the production of sustainable energy. This life cycle assessment data should be used taking into account the technological specifics and environmental implications of manufacturing blade hubs for 1.5 MW wind turbines. When applying this data, users should consider the energy consumption and emissions associated with the production process, as detailed by Xue et al. (2015). It is also important to model the use phase behavior of the wind turbines to understand the overall environmental impact, including their substitution effects on traditional energy sources. This data is applicable primarily to regions with similar wind power infrastructure to the case study of Northeast Inner Mongolia.
