GE is planning to test 3D printing in the on-site production of wind turbine towers, as part of a group which involves LafargeHolcim and COBOD, following the successful demonstration of a 10-meter prototype. Tower size is traditionally limited by logistical issues imposed by road size, meaning that maximum dimensions are typically 100 meters for height and 4.5 meter for diameter. With the potential for heights of up to 200 meters, the group has claimed that a 5 MW turbine would generate 33% additional power with a larger tower, due to access to higher wind speeds at higher altitude. The IEA has released its monthly oil statistics for March 2020, reiterating the reasons behind the record low prices seen across the…
