“…Significant emission reductions can be achieved by replacing diesel-powered buses with battery-electric buses [3] or Fuel Cell Electric Buses (FCEB), fueled by renewable hydrogen [4,5]. With a refueling time similar to traditional diesel-powered buses (i.e., 10 min, as opposed to 3 h -5 h for electric buses) and promising performance over extended driving ranges (i.e., 250 km) [6], FCEB achieve significant interest across Europe, with over 90 FCEB deployed in 2018 [7].…”

“…Production of renewable hydrogen using wind and solar power Ghana, in general, is faced with the threat of an energy crisis mainly due to the growing population and limitation of resources. The ever-increasing population involves rising demand for energy and expanded infrastructure to match the growth (Gunawan et al 2020). The country has created policies to deploy wind and solar energy for hydrogen production and supply electricity.…”

Ghana suffers from inadequate power supply due to increasing demand though it is amongst the African nations with the highest access to electricity. This research aims to assess the techno-economic potential of wind and solar energy potential for Ghana's northern part. We employ the Weibull distribution function, levelized cost of energy, and net present cost metrics for the economic study. The wind and solar energy resource's structure generated 72,284 kWh yearly. Both systems were identified to be too expensive if implemented under the current financing conditions in the country. The PV systems generated 38,859 kWh/year, representing 53.76% of the total electricity generated in a year, generating renewable hydrogen in the country. The findings show that sizing and management of renewable plants will fulfill the basic annual cooking demands of the populations, which are 785 kg H 2 in Ghana. The countries' capacity for developing solar hydrogen plants is further suggested by generating new solar hydrogen opportunity charts. Considering the significance of hydrogen energy under the renewable energy output, we recom-mend using hybrid systems for hydrogen production. The findings reveal which flexibility options are critical in key stages of the energy transition to a 70, 80, 90, and 100% renewable energy system.

“…Although this equalization method reduces the energy loss, the circuit design is complex and the hardware implementation cost is high. In some studies, a new type of equalization circuit is designed by combining the advantages of active equalization and passive equalization, which improves the equalization efficiency to a certain extent and simplifies the circuit design [7][8][9][10]. In addition to improving balance efficiency and reducing balance time, different balancing strategies are proposed, which are mainly defined according to the battery cell voltage or the remaining capacity of the single battery.…”

Lithium-ion batteries, the core components of electric vehicles, have received unprecedented attention and undergone development in the era of huge energy demand. The traditional clustering algorithm cannot meet the requirement of the consistency of lithium battery distribution. In this study, we provide an improved K-means algorithm to meet the battery distribution needs of enterprises and combine it with reality. This model includes an early data processing model and a battery comparison method based on the new K-means algorithm. In the battery data processing model, the preprocessing process approach and actual production standards preclude problematic batteries. In the battery comparison algorithm, the number of batteries in each cluster becomes equal after the battery comparison. The algorithm can ensure the internal characteristics of lithium-ion power batteries, and, at the same time, after the matching is completed, the number of lithium batteries in each cluster is equal.
