In Kansas and Oklahoma, over 5,000MW of wind and solar could be deployed by 2025 using the tech. Image: Getty.
Technologies to help tackle grid congestion could double the volume of solar and wind deployed by 2025, according to a new study.
The study – undertaken by the Brattle Group on behalf of the WATT Coalition – identifies how three Grid-Enhancing Technologies (GETs) could boost the technologies, using the Southwest Power Pool (SPP) grid as an illustrative case study.
It found that renewables curtailments in Kansas and Oklahoma are likely caused by transmission congestion and that the three GETs – Advanced Power Flow Control, Dynamic Line Ratings and Topology Optimisation – could enable the two states to integrate 5,200MW of solar and wind generation currently in interconnection queues by 2025, with this being over double the development possible without the technologies.
Powder bed metal additive manufacturing (AM) processes typically use up to 20kg of powder for each 1kg of manufactured part, so AM users must be able to effectively handle and recycle vast amounts of powder during the process. In the current generation of AM machines, the powder handling equipment provides a potential risk to powder traceability and powder quality.
PowderCleanse, which is in its final stages, set out to develop and demonstrate an effective solution for powder management which utilises digital connectivity to monitor and control every aspect of the process. Key innovations are being developed for metal powder sieving, online process monitoring, foreign body contamination detection and fully enclosed powder handling environments.
Porsche unveils new electric drive housing from 3D printing and additive manufacturing

Porsche has unveiled its first-ever electric drive housing created entirely using 3D printing and additive manufacturing technology. According to the German carmaker, 3D printing and its latest additive laser fusion process are opening new possibilities in creating high-stress components for low-volume series production.
“This proves that additive manufacturing with all its advantages is also suitable for larger and highly-stressed components in electric sports cars,” says Falk Heilfort, Project Manager in the Powertrain Advance Development department at Porsche Development Centre in Weissach.
Porsche’s 3D-printed drive housing is 10-percent lighter than a similar part created using traditional casting techniques. It benefits from unique lattice structuring in high-stress areas that only became possible due to 3D printing, added P
