Jakarta (2025-03-11) – A report published in july 2024 highlights the potential for humans to tap into underwater “mines” of electricity and an “unlimited energy source” found in the ocean depths.
Electricity is essential for nearly all daily human activities. This dependence coincides with the growing need to shift away from fossil fuels and toward renewable energy sources.
Diversifying electricity sources will enhance energy security.Relying on a single source, such as fossil fuels, carries a high risk of supply disruptions.
The Promise of Ocean Energy
The integration of new technologies and renewable energy sources enables diversification of the energy mix, ensuring a more stable and reliable supply.
Unlimited Electricity Mines Beneath the Sea
Vast and inexpensive sources of hydrogen and electricity have been discovered on the seabed. The July 2024 report reveals the extraordinary potential for extracting offshore geothermal energy by harnessing the movement of underwater tectonic plates.
According to the report, meaningful untapped potential exists to provide the world with cheaper and more accessible electricity.
Geothermal energy could become an inexhaustible and stable energy source, drastically reducing electricity prices. Unlike other promising technologies like nuclear fusion, geothermal energy is already operational.
Unlike solar and wind energy, it is available 24/7. Moreover, its infrastructure costs are reportedly much lower.
However,geothermal exploration to find optimal installation sites is expensive and does not always yield the expected results. Therefore, companies tend to install these facilities in places with easy access to highly fractured and permeable hot rocks, which greatly limits their deployment and prevents expansion.
some entities have developed new technologies to address this issue, technologies that are already injecting energy into the electricity grid. However, the report states that extraction is simpler if done on the seabed.
Specifically, the report mentions installing geothermal power plants in areas of seafloor spreading, a process where tectonic plates continuously separate, creating new pieces of the Earth’s crust.
The report estimates that approximately 65,000 square kilometers of land exist where magma from these large underwater fissures is very close to the surface. It suggests that in certain areas, it would be more sensible to extract fresh water from the steam passing through turbines and perform electrolysis to produce green hydrogen.
Various resources can be exploited in this way.On one hand, there is fresh water as a byproduct. on the other hand, there is hydrogen, and ammonia, which can be converted into hydrogen, can also be processed into an energy source. In short, this is a mine of perpetual energy sources beneath the sea.
Ocean Energy Technologies
Several technologies are being developed to harness the power of the ocean. these include:
- Ocean Wave Energy Conversion: Captures kinetic and potential energy from moving and elevated water.
- Tidal and Current Energy: Utilizes the predictable flow of tides and currents to generate electricity.
- Ocean Thermal Energy: Exploits temperature differences in the ocean to produce power.
The Blue Economy and Offshore Renewable energy
the ocean holds immense potential for renewable energy generation. The theoretical resource potential of ocean energy is sufficient to meet present and projected global electricity demand well into the future. Ocean energy is highly predictable and well-suited to provide baseload power.
The theoretical potential for electricity generation differs among technologies,with the aggregated potential being significant.
Unlocking the Ocean’s Energy Potential: Your Questions Answered
The ocean is increasingly recognized as a vast and largely untapped source of renewable energy.A recent report highlights the potential for underwater geothermal energy and other ocean-based technologies to revolutionize our energy supply. Here’s a breakdown of what this could mean for the future of energy.
The Basics of Ocean Energy
What is ocean energy and why is it crucial?
ocean energy refers to all forms of renewable energy derived from the ocean. This includes wave energy,tidal energy,ocean thermal energy,and geothermal energy extracted from the seabed. It is important becuase:
It’s Renewable: Ocean energy sources are naturally replenished and sustainable.
It’s Abundant: The theoretical potential of ocean energy could meet current and future global electricity demands.
It Enhances Energy Security: Diversifying energy sources reduces reliance on fossil fuels and mitigates risks of supply disruptions.
What are the main types of ocean energy technologies?
Different technologies are being developed to harness the ocean’s power:
Ocean Wave energy Conversion: Converts the kinetic and potential energy of waves into electricity.
Tidal and Current Energy: Uses the predictable flow of tides and currents to generate electricity.
Ocean Thermal Energy Conversion (OTEC): Exploits temperature differences between surface and deep ocean waters to produce power.
Offshore Geothermal Energy: Extracts geothermal energy from the seabed, notably in areas of seafloor spreading.
Delving into Offshore Geothermal Energy
What is offshore geothermal energy?
Offshore geothermal energy involves tapping into the Earth’s heat beneath the ocean floor to generate electricity. This is particularly promising in areas where tectonic plates are spreading apart, creating thinner crust and bringing magma closer to the surface.
According to a July 2024 report, meaningful potential lies in extracting offshore geothermal energy by harnessing the movement of underwater tectonic plates.
Where is offshore geothermal energy most accessible?
Offshore geothermal energy is most accessible in areas of seafloor spreading, where:
Tectonic plates are continuously separating.
Magma is closer to the surface due to thinner crust.
There are approximately 65,000 square kilometers of land suitable for geothermal power plants.
The ocean crust is notably thinner at rift zones,around 5km,in comparison to continental crust which ranges from 30-100km.
What are the benefits of offshore geothermal energy?
Consistent Energy Supply: Unlike solar and wind, geothermal energy is available 24/7.
Lower Infrastructure Costs: Reportedly, geothermal infrastructure costs are lower compared to other energy sources.
Potential for Hydrogen Production: Steam from geothermal vents can be used to produce fresh water and, through electrolysis, green hydrogen.
Reduced Need for Extensive Power Grids: Geothermal power can be harnessed and used locally, reducing the need for long-distance energy transportation.
What are the challenges of offshore geothermal energy?
Exploration Costs: Finding optimal installation sites is expensive, and success isn’t guaranteed.
Technical Difficulties: Extracting geothermal energy from the ocean floor presents formidable technical challenges.
How does offshore geothermal energy extraction work?
The process involves installing geothermal power plants in areas of seafloor spreading, using the steam from underwater fissures to drive turbines. This process can also yield fresh water as a byproduct, which can be used to produce hydrogen through electrolysis.
Self-sustaining, submersible, remotely controlled turbine generators on the ocean floor would convert energy to electricity at mid ocean rift zones, which reduces the energy loss from transferring heat to the surface
What resources can be derived from offshore geothermal energy?
Electricity: The primary product.
fresh Water: A byproduct of steam extraction.
Hydrogen: Produced through electrolysis of fresh water.
* Ammonia: Processed into an energy source or converted into hydrogen.
The Future of ocean Energy
What is the “Blue Economy” and how does ocean energy fit in?
the Blue Economy refers to the sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of the ocean ecosystem. Ocean energy is a key component, offering a way to generate clean energy while utilizing the ocean’s vast potential.
How significant is the potential for ocean energy?
