“…In the last decade, research on the estimation of marine resources has greatly increased around the world. Examples of this kind of research include: energy from waves [4][5][6][7][8][9][10][11][12], ocean currents [13][14][15][16], salinity gradients [17][18][19][20], and thermal gradients [21][22][23]. Other works concerned with energy resource assessment for specific countries, such as Korea [24] and Colombia [25], have also been published.…”

The Atlantic and Pacific coasts of Mexico offer a variety of marine energy sources for exploitation. Although the Mexican government has made important efforts to reduce its dependence on fossil fuels, national participation in clean energies is still limited in terms of electricity production. This paper presents a practical theoretical assessment of marine energy sources around Mexico, with the aim of identifying potential zones for subsequent, more detailed, technical evaluations and project implementations. The energy sources considered are ocean currents, waves, salinity, and thermal gradients. Using global databases, the percentages of energy availability for the defined thresholds were computed to establish the prospective regions with the most persistent power availability. This approach proved to offer more meaningful information than simple averaged values. Moreover, some environmental and socio-economic factors to be considered for future ocean energy resource assessments in Mexico were also discussed. The results show that the wave energy potential is highest in the northwest of Mexico (~2–10 kW/m for more than 50% of the time), and that there is a constant source of ocean current energy off Quintana Roo state (~32–215 W/m2 for more than 50% of the time). The thermal gradient power is more persistent in the southwest and southeast of the country, where ~100–200 MW can be found 70% of the time. The salinity gradient energy is strongest in the southeast of Mexico. The practical approach presented here can be extended to perform preliminary resources assessments in regions where information is scarce.

“…The latter study predicted an absolute power limit at 30 TW, beyond which increasing water flow rates would induce mixing of the thermocline and reduce the global power potential [16]. Further studies include mapping the thermal difference between proposed cold and warm water resource depths and mapping the predicted power output from representative OTEC plant model [17]. respectively, with 5-6 ˚C temperature swing between mean summer and winter values.…”

Technological advances in marine renewable energy allow for various methods of extracting energy in the form of electrical power from the ocean. One method is through the process of ocean thermal energy conversion (OTEC). This study assesses the distributions of electrical power that can be extracted from the ocean around the state of Florida. The OTEC resource is analyzed with the combination of a state-of-the-art ocean circulation model, the Hybrid Coordinate Ocean Model, along with a state-of-the-industry OTEC plant model in order to predict the attainable power values offshore Florida. The power predictions are then constrained by local cold deep sea water replenishment to provide an upper limit to the sustainable OTEC resource. The thermal resource is used as input to the plant model to predict the potential power production. The resource data is then validated through the comparison against in situ oceanic measurements to safeguard the quality of the predicted power values.

“…The information presented herein is intended to help improve understanding of the locations and characteristics of the resources and how they might contribute to the future energy portfolio of the United States. This work is based on several DOE-funded resource assessment studies (Haas et al 2011;Haas 2013;Jacobson, Hagerman, and Scott 2011;Jacobson et al 2012;Ascari et al 2012), a review of these studies performed by the National Research Council (National Research Council (NRC) 2013), and work to update and improve resource assessment studies currently underway at the National Renewable Energy Laboratory (NREL), Pacific Northwest National Laboratory (PNNL), and Sandia National Laboratories (Sandia). Accordingly, this report presents the most up-to-date marine energy technically recoverable utility-scale resource data for the United States.…”
