Liquid organic hydrogen carriers (LOHCs) are considered as promising candidates for large-scale hydrogen storage, which offers significant advantages in terms of hydrogen storage density, ease of storage and transportation. NPhCZ (N-phenylcarbazole)/18H-NPhCZ (perhydro-N-phenylcarbazole) is proposed as a typical system with high hydrogen storage capacity. However, low dehydrogenation activity and selectivity of catalysts restrict the cyclic efficiency of hydrogen storage. In this study, the efficient catalysts are designed by the immobilization of ultrafine, highly dispersed Pd nanoparticles onto Ni, N co-doped carbon materials with defect structures by the wet chemical reduction. The Pd/Ni@NC-10 catalyst exhibits the highest catalytic performance with 100% conversion, 81.9% selectivity of NPhCZ and 6.48 wt% hydrogen release amount. Combined with XRD, HRTEM, Raman, XPS, H2-TPR, N2 physisorption characterization methods and DFT calculations, it is found that the doped Ni species could both increase the dispersion of loaded Pd nanoparticles, as well as regulate the electronic state around Pd and the ratio of Pd0/Pd2+, which in turn reduced the reaction activation energy of the rate-limiting step. The evident synergistic interaction between Pd nanoparticles and Ni, N co-doped carbon brings the enhancement of dehydrogenation efficiency. Besides, the spent catalysts are measured by XRD, TEM, XPS and evaluated for the dehydrogenation reaction, indicating that Pd/Ni@NC-10 shows good structural stability, durability and recyclability. It provides practical guidance for the design of LOHCs dehydrogenation catalysts. © 2023, The Authors. All rights reserved.

Experimental and simulation investigation of a Savonius vertical axis wind turbine for residential applications: a case study in Indonesia

The aim of this study was to investigate several geometric designs to improve the performance of a Savonius vertical axis wind turbine (SVAWT) at low wind speeds. The SVAWT models were numerically tested using ANSYS prediction software to determine the best performance. Furthermore, a SVAWT prototype was experimentally evaluated in subsonic wind tunnels at wind speeds of 1–5 m/s to determine the electrical power produced. The experimental results were used as input parameters for HOMER tools to optimise renewable energy systems and establish the prototype’s techno-economic environmental viability for satisfying the residential demand load. The simulation results showed that the maximum power coefficient obtained was 0.25 for a SVAWT model with a twist angle of 45° at a wind speed of 5 m/s. The experimental results showed that the modified SVAWT produced 494.9 W of electrical power at a wind speed of 5 m/s. The results confirmed that the cost of electrical energy following an initial investment in the optimised renewable energy system configuration (a grid-connected 1-kW SVAWT with a–kW electrical converter and two battery strings) was 0.0963/kWh and 4,425. This setup achieves a 65.8% renewable fraction, cutting CO2 emissions by over 53.71%, fit for residential use. © 2024 Informa UK Limited, trading as Taylor & Francis Group.
