Recent research published in the journal Heliyon sheds light on the potential of marine renewable energy, a sector that remains largely untapped despite its promise. The study, led by Ephraim Bonah Agyekum from the Department of Nuclear and Renewable Energy at Ural Federal University, employs both traditional and bibliometric analysis to explore the current landscape of marine energy.
Marine renewable energy, which includes sources like tidal and wave power, is considered a promising avenue for sustainable energy production. However, the research highlights several hurdles that have hindered its growth. Key challenges identified include high initial capital costs, a lack of standardized device designs, insufficient legal and regulatory frameworks, and competition from other renewable sources. Furthermore, the harsh conditions of the ocean environment pose significant challenges to the survivability of various technologies.
Despite these obstacles, the study outlines several commercial opportunities that could drive the sector forward. Agyekum notes that “the availability of renewable energy targets and international greenhouse gas (GHG) emissions reduction targets present significant opportunities for marine energy.” The potential for job creation and skill transfer from established offshore industries also stands out as a major benefit.
The bibliometric analysis conducted in the study reveals that tidal power is currently the focal point of research within the marine energy sector. Many studies aim to enhance the efficiency of tidal energy technologies or to identify optimal sites for deploying marine renewable systems. This focus indicates a growing interest and investment in the technology, which could lead to advancements that make it more commercially viable.
To address the challenges and capitalize on the opportunities, the research suggests several actionable recommendations. Agyekum emphasizes the importance of “strong cooperation between the government and private sector,” as well as increased public education and collaboration with existing marine industry players. Additionally, boosting research and development efforts could pave the way for innovation in the sector.
As the global demand for renewable energy continues to rise, marine energy presents a unique opportunity for businesses and governments alike. By overcoming existing challenges and leveraging the identified opportunities, stakeholders in the marine energy sector can contribute to a more sustainable energy future while also benefiting economically.
