A focus on clean energy transition
Michigan-based consulting firm Ducker Carlisle has released a report that outlines projected developments and opportunities as well as potential problems in the global shift to cleaner power. Global Energy Transition Outlook predicts that market growth will happen not only in large-scale utility upgrades but also in small- and mid-scale electrification projects.

A new helical axis stellarator called Helias-Heliac Hybrid Stellarator(HHHS) is based on the modulated l = 1 helical coil. In order to obtain Helias-like and Heliac-like configurations, toroidal coils, poloidal coils and an additional l = 1 helical coil are adjusted to control magnetic field spectrum. It is shown that the bumpy field with opposite sign to l = 1 helical field is essential to minimize the neoclassical ripple transport. An HHHS configuration with sufficient magnetic well and reduced neoclassical ripple transport is demonstrated.
