The rapid increase in cooling demand for air-conditioning worldwide brings the need for more efficient cooling solutions based on renewable energy. Seawater air-conditioning (SWAC) can provide base-load cooling services in coastal areas utilizing deep cold seawater. This technology is suggested for inter-tropical regions where
Intriguingly, all the increase in ocean heat storage (OHS) is attributable to the passive component, with the ocean circulation change playing almost no role. In the Southern Ocean, both the active and the passive ocean heat transports are overcompensated by the reverse atmospheric heat transport via the Bjerknes

Heat transports on a monthly basis are calculated using surface energy flux data from a previous study together with the computed heat storage change. There is a large annual cycle in heat storage change at almost all latitudes with the largest amplitude in latitudes where the western boundary currents dominate.
Significant ocean warming and accelerating OHC changes are also consistent with the increase in net radiative energy absorbed by of historical ocean heat storage and transport . Proc. Natl
Heat storage within the Earth system is a fundamental metric for understanding climate change. The current energy imbalance at the top of the atmosphere causes changes in energy storage within the
Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications [4] and power generation. TES systems are used particularly in buildings and in industrial processes.
Here, we study the mechanism for the initial response of the heat transport to global warming from the ocean perspective, with an emphasis on the role of ocean heat storage and coupled
Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored by oceans. To calculate the ocean heat content, it is necessary to measure ocean temperature at many different locations and depths. Integrating the areal density of a change in enthalpic energy over an ocean basin or entire ocean gives the total ocean heat
By Elliot Clark December 12, 2023 3 Mins Read. Thermal energy storage involves heating or cooling a substance to preserve energy for later use. In its simplest form, this process includes heating water during periods of abundant energy, storing it, and later using the stored energy. This utilizes storage options like water, ice-slush-filled
To compare the two basins'' efficiencies in storing heat, we look at basin OHC changes divided by the respective basin''s surface area (in J m −2).After 200 years'' warming, the final anomalous OHC difference, Δ OHC SB − Δ OHC LB, is 3.45 × 10 9 J m −2 (Figure 1b), and in terms of heat storage rates in W m −2, this translates to a time
The rate of warming of the global ocean, calculated from a lin-. ear least squares fit, using the GF reconstruction between 1955. and 2017 is estimated at 0.22 ± 0.05 and 0.30 ± 0.06 W/ m. in
However, our current understanding of the spatial distribution of ocean heat uptake (OHU) and storage is limited, not least because of sparse observations with large

In contrast, at 45 S we see anomalous convergence of ocean heat transport and heat loss at the surface. As a result, the wind-induced ocean heat storage (OHS) peaks at 46°S at a rate of 0.07 ZJ
Anthropogenic global surface warming is proportional to cumulative carbon emissions 1, 2, 3; this relationship is partly determined by the uptake and storage of heat and carbon by the ocean 4. The
Studies of the role of the ocean in climate invariably focus on SST. However, what is really important is the persistence of SST anomalies that depends on
Osmotic power, salinity gradient power or blue energy is the energy available from the difference in the salt concentration between seawater and river water. Two practical methods for this are reverse electrodialysis (RED) and pressure retarded osmosis (PRO). Both processes rely on osmosis with membranes. The key waste product is brackish water.
1. Introduction The ocean covers 70.8% of the Earth''s surface, with a total area of about 360 million km2. It plays a significant role in maintaining the ecological balance of the environment on Earth. Besides, the ocean also contains plenty of resources, e.g., mineral [1], biological [2], water [3], and renewable energy resources [4].
Abstract. Ocean heat storage due to local addition of heat ("added") and due to changes in heat transport ("redistributed") were quantified in ocean-only 2xCO2 simulations. While added heat storage
What happens to heat energy once absorbed by the ocean? The heat absorbed by the ocean does not disappear: it may circulate and become redistributed over time. For instance, it can melt ice shelves, heat the atmosphere or land as part of the Earth
We find that the global ocean absorbed heat during this period at a rate of 0.30 ± 0.06 W/ m 2 in the upper 2,000 m and 0.028 ± 0.026 W/ m 2 below 2,000 m, with large decadal fluctuations. The total
Climate models show more skill in simulating ocean heat storage by the pre-industrial circulation compared to heat redistribution,
Atmospheric ozone concentrations have dramatically changed in the last five decades of past century. Herein we explore the effects of historical ozone changes that include stratospheric ozone depletion on Southern Ocean heat uptake and storage, by comparing CESM1 large ensemble simulations with fixed-ozone experiment. During
Among them, Webb [11] et al. applied ocean thermal energy conversion technology to SLOCUM and transformed SLOCUM into an underwater thermal glider. NASA''s Jet Propulsion Laboratory has joined forces with several units to develop a new unmanned submersible powered by ocean thermal energy, which can replenish its
Abstract The observational record shows a substantial 40-yr upward trend in summertime westerly winds over the Southern Ocean, as characterized by the southern annular mode (SAM) index. Enhanced summertime westerly winds have been linked to cold summertime sea surface temperature (SST) anomalies. Previous studies have

Meanwhile, we look into the trend of the vertically integrated OHC over 1861–2005, or equivalently, the ocean heat storage (OHS). We find a different pattern of OHS from OHU. Anthropogenic

Abstract A simple three-dimensional thermodynamic model is used to study the heat balance in the Gulf Stream region (30°–45°N, 40°–75°W) during the period from November 1992 to December 1999. The model is forced by surface heat fluxes derived from NCEP variables, with geostrophic surface velocity specified from sea surface height
This study provides an analysis of the Mediterranean Sea surface energy budget using nine surface heat flux climatologies. The ensemble mean estimation shows that the net downward shortwave radiation (192 ± 19 W m −2) is balanced by latent heat flux (−98 ± 10 W m −2), followed by net longwave radiation (−78 ± 13 W m −2) and sensible
But the warming did not occur at the surface; it showed up below 10 meters (32 feet) in depth, and mostly between 100 to 300 meters (300 to 1,000 feet) below the sea surface. They published their results on
