Given the long distance between geo-dispersed variable renewable energy (VRE) and cascaded hydropower, an innovative and flexible integration of cascaded multi-terminals (CMT) technology has been adapted. Three key issues for hybrid power system, that zoning impact on its optimization, flexibility dispatch between hierarchical converter stations, and solutions under power balance constraints for …

The transition to low-carbon technologies in agriculture has drawn increasing attention, with battery electric tractors (BETs) emerging as a promising alternative to conventional diesel-powered machinery. This study presents a systematic literature review following PRISMA guidelines to assess the economic feasibility of BETs and factors influencing farmers’ willingness to adopt them. We searched …

Magnetic refrigeration at cryogenic temperatures represents a promising cleaner-production approach to reduce the energy intensity of hydrogen liquefaction. Experimental development of cryogenic active magnetic regenerators (AMRs) has been limited by the scarcity of magnetocaloric materials (MCMs), complex fluid–solid interactions, and the challenges of scaling up laboratory prototypes. Here, we …

The rapid transition toward inverter-dominated renewable power systems has substantially reduced rotational inertia, resulting in faster frequency excursions and heightened vulnerability to disturbances. In this context, green hydrogen-enabled power systems—integrating electrolyzers, fuel cells, hydrogen storage, and hydrogen-fueled turbines—are increasingly recognized as a promising pathway to e…
