Subsea Power Hub Tested in Aberdeen

Subsea energy storage and power generation specialists EC-OG said it has demonstrated the capabilities of its Subsea Power Hub (SPH) for powering subsea production equipment using battery power alone, during a recent workshop test program in Aberdeen.During the trials, supported by the Oil & Gas Technology Center (OGTC) and a North Sea operator, the SPH was used to power a commercial Subsea Control Module (SCM) and local power distribution system. By operating the SCM using lithium ion battery technology, located within EC-OG’s proprietary Energy Storage and Intelligent Energy Management

, which will in the future enable Eni to convert mature offshore platforms into renewable energy generation hubs.The pilot plant was installed at the Ravenna offshore site by Eni’s Central Northern District and has been integrated into a hybrid smart grid system featuring photovoltaics and energy storage.It reached a peak power output of over 51 kW, or 103% of its nominal power. This technology is suitable for powering medium and large offshore assets and, in the future, will enable Eni to convert mature offshore platforms into renewable energy generation hubs.Waves are the most underutilized

Ocean Power Technologies Pact with NEC Energy Solutions

The provider of ocean energy solutions Ocean Power Technologies (OPT) signed a letter of intent to enter into a long-term supply agreement with NEC Energy Solutions, global leader in utility scale energy storage.Under the terms of the supply agreement, NEC ES will supply lithium ion batteries for OPT's subsea battery solutions.George H. Kirby, President and Chief Executive Officer of OPT, said: "NEC is a supplier of lithium ion batteries for our subsea battery solutions. Their long-standing leadership in the industry, as well as their dedication towards providing versatile, high-quality

Given OPT’s expertise in offshore energy storage systems from existing PB3 technology, the subsea batteries will provide an opportunity for OPT to differentiate through technical, cost and delivery leadership. The specialized knowledge required of pressure regulated battery solutions can create a significant barrier to entry, thus potentially

The demands of operating in harsh environments made these tools robust and inspired fully waterproof variants. Unfortunately at the time limitations in energy storage, autonomy and telemetry made seafloor crawling robots a novelty rather than a productive tool. This has changed.Through the surfToday C-2 Innovations, Inc., (C2I) has developed a family of capable, production ready, seafloor crawling robots to take users back through the surf zone and into the

speed.Through an exclusive partnership with L-3-Open Water Power the micro-UUV will pioneer the use of aluminum seawater batteries. This new technology harnesses the energy of a chemical reaction between seawater and specially developed, high-purity aluminum alloys. The result is an inherently safe energy storage solution with a dramatic increase in energy density. This technology will be tested in 2018 and is anticipated to be available commercially on Riptide UUVs in 2019.Through both electronics optimization and new energy technologies Riptide is taking compact UUVs further than ever before.Faster:

At the same time, as vehicles go deeper, the pressure vessels become excessively heavy and expensive and AUVs with internal batteries become limited by the fact that these batteries have to be recharged. The Consortium aims to produce a pressure-tolerant battery pack that delivers increased energy storage and that can be hot swapped to improve operational utilization.   The first phase of the project was completed at the National Oceanography Centre (NOC) in Southampton and involved repeatedly testing Li-S cells at pressures and temperatures equivalent to undersea depths of 6,000m.
