DNV Validates Efficiency of Flocean's Desalination Tech
gas emissions and consumes 5% of its power.To verify these results in real-world conditions, the Flocean Zero project launched in November 2024. Initial data analysis confirmed that the deep ocean environment provides optimal conditions for high-efficiency desalination while dramatically reducing energy requirements. Efficiency gains are achieved through two advantages, natural pressure utilization and superior water quality.By placing reverse osmosis systems at 400-600 meters depth, Flocean harnesses natural hydrostatic pressure to drive filtration without energy-intensive pumping systems.Deep ocean

uptick in demand for uncrewed underwater vehicles (UUVs) where we sell both sonar and batteries to AUVs and provide minehunting solutions to Navies with our KATFISH towed synthetic aperture sonar solution. The emergence of a new class of UUVs, the Extra Large UUV (XLUUV) is driving much higher energy requirements in UUVs and our subsea battery business is benefitting.“Many countries and Navies around the world are in various stages of upgrading their subsea surveillance equipment, with underwater solutions such as towed sonar or autonomous underwater vehicles (AUVs) that are deployed from crewed
How Floating Solar Panels Could Power Future Population Hotspots
tracks. Author-supplied, using OpenStreetMap base, CC BY-NDSolar power rules by mid-centuryOn current trends, the global economy will be largely decarbonized and electrified by 2050, supported by vast amounts of solar and wind energy.About 70 square kilometers of solar panels can provide all the energy requirements of a million affluent people in a zero-carbon economy. The panels can be placed on rooftops, in arid areas, colocated with agriculture, or floated on water bodies.But countries with high population densities, such as Nigeria and Indonesia, will have limited space for solar energy harvesting
Corals Make Light Work of Photosynthesis Despite Lack of Sunshine
found at 54m depth, only one percent of the surface light was available likely due to the rich phytoplankton community present in the mesophotic zone at Ashmore Reef, which is common for the eastern Indian Ocean region. Three of the five coral species examined were still able to meet their daily energy requirements via photosynthesis, which indicates that these species have a remarkable ability to efficiently use the low amount of light available. The remaining two species obtained most of their nutritional requirements by increasing the amount of filter feeding undertaken.”Research co-author Dr

changes accompanying the reversible electrochemical interconversion of water to hydrogen and oxygen gases, providing soft VB displacement for subsea vehicles. That description also suggests it can supply breathing oxygen for a manned system as well. We’d have to look closely at the energy requirements of said system. Gaseous CO2 liquifies at a pressure of just 5.2 bar (74psi) between a temperature range of -56°C (-69°F) and 31°C (87°F), so that could be used near-surface from a pressurized liquid CO2 source.

The company also uses air source heat pumps, is ISO 50001 Energy Management System certified, and has had a Building Management System installed for a number of years, helping it to make the most efficient use of energy for heating and power. Any further energy requirements are purchased from a certified renewable energy supplier, Sonardyne said.The company is also considering making investments in large-scale batteries and grid services, which will benefit the company’s access to and cost of renewable energy. They will also provide additional storage to
