DOE Launches $1.7 Million Marine Energy Prize

that harness the power of the ocean.“Marine energy technologies have incredible potential to power systems out at sea that serve broad societal needs, like collecting data about our vast and largely unexplored oceans,” said Jeff Marootian, Principal Deputy Assistant Secretary for Energy Efficiency and Renewable Energy. “I’m excited to see the inventive concepts competitors develop and how they can help advance our goal to achieve net-zero emissions across all sectors of our economy by 2050.”Concepts can power any off-grid use in the ocean with marine energy, which includes

Most Data Lives in the Cloud. What if it Lived Under the Sea?

Cloud is another American company doing so. China’s Shenzhen HiCloud Data Center Technology Co Ltd has deployed centers in tropical waters off the coast of Hainan Island.Why move data centers under the waves?Underwater data centers promise several advantages over their land-locked cousins.1) Energy efficiency - The primary benefit is a significant cut in electricity consumption. According to the International Energy Agency, data centers consume around 1–1.5% of global electricity use, of which some 40% is used for cooling.Data centers in the ocean can dissipate heat in the surrounding water

New Thermal Buoyancy Engine Design Proposed for Underwater Gliders

material to harvest thermal energy as the temperature of seawater drops from surface temperatures of around 20 to 30 °C to around 4 °C below 650 feet.The aim of the researchers' work was to achieve a higher energy yield than existing thermal buoyancy engines and therefore enhance the energy efficiency of gliders. To maximize the power output, they designed their thermal engine to have a higher ballast capacity that could therefore provide a large driving force for the glider.This was achieved by fully using the pressure that the engine's phase change material can generate. This amplified

MacArtney to Supply All-electric LARS for SMD ROV

to integrate SMD’s next-generation EV work class ROV (WROV) technology, specifically for the Atom-EV.MacArtney noted its eLARS offers several environmental benefits, including reduced risk of oil spillage with zero pressurized oil over water. The system provides approximately 30% better energy efficiency than traditional hydraulic systems, and maintenance is reduced by up to 50%, with the eLARS being fully electric, the company said.Related: Rovco Invests in SMD's EV Work Class ROVRelated: MacArtney Puts First All-electric LARS into Productio

CO2 emissions to limit climate change. Reducing emissions from of the energy sector requires urgent action on a global scale, and while a global energy transition is underway, further action is needed to reduce carbon emissions and mitigate the effects of climate change. Renewable energy and energy efficiency measures can potentially achieve 90% of the required carbon reductions. Baker Hughes is an energy technology company. As an energy technology company, we are aiming for emissions reductions rather than eliminating a particular fuel source. To support with emissions reductions and decarbonization
