In this paper, we present a fused flight dynamics and wake interaction modeling framework for arrays (farms) of tethered wind and marine hydrokinetic energy systems. The replacement of conventional towers with tethers necessitates a dynamic model that captures the flight characteristics of each system, whereas the arrangement of the systems in an array necessitates a wake interaction model. The integration of these components is unique to the tethered energy systems literature and is applicable to both airborne wind energy systems and tethered marine hydrokinetic energy systems. In the application case study of this paper, we focus specifically on arrays of ocean current turbines (OCTs), which are intended to operate in the deep waters of the Gulf Stream, adjacent to the eastern coast of the United States. In particular, we evaluate the dynamic performance and resulting projected energy output of an array of tethered OCTs, based on real Gulf Stream resource data from an acoustic Doppler current profiler (ADCP) located adjacent to Cape Hatteras, North Carolina.

At a global level, hydrokinetic power has been considered as a renewable energy source, and it has become an attractive alternative for the rural electrification of non-interconnected areas with the presence of water resources. Aspects such as the low rural electrification rate, the increase in energy demand, the decrease in fossil reserves and the climate change, are some of the factors that have driven the use of this technology for the electricity production. The aim of this work is to give a review of the hydrokinetic energy potential of water resources, the requirements and impacts of the implementation of hydrokinetic technology in different countries, and the current development in the Colombian case. At present, it can be observed that the implementation of this technology in different regions of the world, especially in Colombia, has several challenges and barriers, including gaps in knowledge, information and data, such as well as limitations of water resources and infrastructure, finally, impacting on a low adoption of this technology. On the other hand, publications on studies of implementation and potential of hydrokinetic technology have been increasing over time, indicating that this topic has been gaining interest despite the challenges.

Lower Variability

Hydrogen can be produced from various primary resources by using different processes. The full benefits of hydrogen production can be obtained when it is produced from renewable energy resources. Among these emerging renewable energy resources, marine and hydrokinetic (MHK) energy systems lower variability in the energy production. Also, more than 50% of the total US population resides near water bodies. In this paper, a brief review of renewable energy-based hydrogen production systems is provided, the emission level of both conventional and renewable energy sources for producing the same amount of hydrogen are compared using GREET model, and research needs for further MHK-based hydrogen production systems are discussed. The results showed the significant emission reductions obtained from renewable-based hydrogen production systems. Moreover, the study showed the potential of producing the same amount of hydrogen with less resource quantity of wave energy compared to that from other renewables such as solar energy.
