“…Such studies are an important platform from which more targeted policies and project plans can be developed. A number of authors have highlighted this "data paucity" in the African context and noted the negative impact it has for sustainable energy system planning [9][10][11]. This study aims to address this shortcoming by undertaking a continental scale, first order analysis of the technical OWE potential for all African Exclusive Economic Zones.…”

Offshore wind energy is rapidly becoming a technology that developing countries could consider because project costs have recently fallen substantially. Further reductions are expected as the industry matures. For most African coastal states, specific information about their offshore wind potential is not available. This study aims to address this shortcoming by evaluating the technical offshore wind potential of the entire continent using spatially explicit models and long-term satellite data. Two different scenarios were developed to reflect different levels of technological maturity in the wind industry: The shallow-water, near-coast scenario 1 represented the conservative assumption that technology will not improve beyond what is available already now. The deep-water, full-exclusive economic zone (EEZ) scenario 2 assumes the operational availability of floating platforms that would allow it to access wind resources at much deeper water depths across the entire EEZ. It is emphasized that the model results are subject to a number of uncertainties and therefore should be treated as first order estimates only. Both scenarios indicate very good technical offshore wind energy potential for one third of the African coastal states, with Mozambique, South Africa, Somalia, Madagascar and Morocco exhibiting particularly good resources. More than 90% of the offshore wind resources are concentrated in coastal zones associated to three African Power Pools. These are the Southern African Power Pool (SAPP), the Eastern African Power Pool (EAPP), and the Comité Maghrébin de l'Electricité (COMELEC). A joint and integrated development within these power pools could offer a promising approach to utilising offshore wind energy in Africa.

“…Due to the increasing demand for electrical power and the decreases in fossil resources, most countries in the world have urgently turned to renewable and sustainable energy [1,2]. In the past decade, wind power, especially offshore wind power, has developed rapidly and become a significant source of renewable energy to supply electricity throughout the world [3]. By the end of the year 2017 [4], the total installed capacity of wind power has reached 513.5 GW, which is about 4.4 times as large as the capacity of 115.4 GW in 2008.…”

Offshore wind turbine (OWT) structures are highly sensitive to complex ambient excitations, especially extreme winds. To mitigate the vibrations of OWT structures under windstorm or typhoon conditions, a new eddy current with tuned mass damper (EC-TMD) system that combines the advantages of the eddy current damper and the tuned mass damper is proposed to install at the top of them. In the present study, the electromagnetic theory is applied to estimate the damping feature of the eddy current within the EC-TMD system. Then, the effectiveness of the EC-TMD system for vibration mitigation is demonstrated by small-scale tests. Furthermore, the EC-TMD system is used to alleviate structural vibrations of the OWT supported by composite bucket foundations (CBF) under extreme winds at the Xiangshui Wind Farm of China. It is found that the damping of the EC-TMD system can be ideally treated as having linear viscous damping characteristics, which are influenced by the gaps between the permanent magnets and the conductive materials as well as the permanent magnet layouts. Meanwhile, the RMS values of displacements of the OWT structure can be mitigated by 16% to 28%, and the acceleration can also be reduced significantly. Therefore, the excellent vibration-reducing performance of the EC-TMD system is confirmed, which provides meaningful guidance for application in the practical engineering of OWTs.

“…In this century, solving the serious energy and environmental problems is one of the biggest challenges facing the scientific community. In the past 10 years, multiform new energy has had rapid development such as solar energy [ 1 ], wind energy [ 2 ], tidal energy [ 3 ], and so on. However, these new energies are interval energy, which need to be stored for use.…”

In this work, we designed and successfully synthesized an interconnected carbon nanosheet/MoS2/polyaniline hybrid (ICN/MoS2/PANI) by combining the hydrothermal method and in situ chemical oxidative polymerization. The as-synthesized ICNs/MoS2/PANI hybrid showed a “caramel treat-like” architecture in which the sisal fiber derived ICNs were used as hosts to grow “follower-like” MoS2 nanostructures, and the PANI film was controllably grown on the surface of ICNs and MoS2. As a LIBs anode material, the ICN/MoS2/PANI electrode possesses excellent cycling performance, superior rate capability, and high reversible capacity. The reversible capacity retains 583 mA h/g after 400 cycles at a high current density of 2 A/g. The standout electrochemical performance of the ICN/MoS2/PANI electrode can be attributed to the synergistic effects of ICNs, MoS2 nanostructures, and PANI. The ICN framework can buffer the volume change of MoS2, facilitate electron transfer, and supply more lithium inset sites. The MoS2 nanostructures provide superior rate capability and reversible capacity, and the PANI coating can further buffer the volume change and facilitate electron transfer.
