There exists no single optimal way for transporting hydrogen and other hydrogen carriers from one port to the other globally. Its delivery depends on several factors such as the quantity, distance, economics, and the availability of the required infrastructure for its transportation. Europe has a strategy to invest in the production of green hydrogen in Africa to meet its needs. This study assessed the economic viability of shipping liquefied hydrogen (LH2) and hydrogen carriers to Germany from six African countries that have been identified as countries with great potential in the production of hydrogen. The results obtained suggest that the shipping of LH2 to Europe (Germany) will cost between 0.47 and 1.55 USD/kg H2 depending on the distance of travel for the ship. Similarly, the transportation of hydrogen carriers could range from 0.19 to 0.55 USD/kg H2 for ammonia, 0.25 to 0.77 USD/kg H2 for LNG, 0.24 to 0.73 USD/kg H2 for methanol, and 0.43 to 1.28 USD/kg H2 for liquid organic hydrogen carriers (LOHCs). Ammonia was found to be the ideal hydrogen carrier since it recorded the least transportation cost. A sensitivity analysis conducted indicates that an increase in the economic life by 5 years could averagely decrease the cost of LNG by some 13.9%, NH3 by 13.2%, methanol by 7.9%, LOHC by 8.03%, and LH2 by 12.41% under a constant distance of 6470 nautical miles. The study concludes with a suggestion that if both foreign and local participation in the development of the hydrogen market is increased in Africa, the continent could supply LH2 and other hydrogen carriers to Europe at a cheaper price using clean fuel.
Boosting energy consumption, ensuring energy supply security, and mitigating emissions are critical global concerns, especially during the surge in energy prices, continuous expansion in income level and persistent economic integration with other countries, and climate change. The existing evidence on the determinant of renewable energy is still in its early stages; however, there is currently limited empirical evidence regarding the determinant of renewable energy in Australia. Therefore, this study probed into the effect of the asymmetric effect of economic globalization on renewable energy usage in Australia, which prior studies in the literature have neglected. The study employed carbon emissions, economic growth, and oil price as other regressors. The dataset for the period spanning from 1970 to 2018 was analyzed using the nonlinear autoregressive distributed lag. Evidence from the empirical analysis reported that the positive variation in economic globalization has a positive and significant effect on renewable energy, thus the rise in economic globalization promotes renewable energy. Meanwhile, the negative variation in economic globalization has a neutral impact on renewable energy. Furthermore, economic growth and oil price positively and significantly affect the usage of renewable energy in Australia. Moreover, carbon emissions have a negative and significant effect on renewable energy. Furthermore, the wavelets coherence was also for the robustness test, which reports positive co-movement between all regressors and renewable energy, except for CO2 emissions (negative co-movement). Economic globalization, economic growth, and CO2 emissions drive renewable energy, while renewable energy leads to oil prices in Australia. This study offers significant and crucial suggestions to policymakers in Australia, emphasizing the need to prioritize environmental sustainability and promote economic globalization to foster the growth of the clean and efficient energy sector.
The Turkish Republic of Northern Cyprus is among the many countries which have long embraced the use of social media and social networking sites. The frequent access of and use of social networking platforms have been intensified by the presence of many institutions of learning and the increasing number of foreign students and tourists from across various countries of the world. The Northern Cypriot locals are not left out in the social media activities. The common networking sites frequently used in the setting include but not limited to Facebook, e-mail and twitter. Northern Cyprus is clearly multilingual but three languages seem to be common in communication: Turkish, English and Arabic. However, on the social media, broadcast messages, adverts and bulk sms from service providers are predominant in either English or Turkish. The methodology will be quantitative through survey. The research will compare the use of English and Turkish languages on social media in north Cyprus to determine which is more frequently used and more accessible to social media users. The possible findings would be that English and Turkish are in a competitive situation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
