This year, Scottish renewable energy firm, Sustainable Marine will deliver the first development phase of the Pempa’q In-stream Tidal Energy Project, located in the Bay of Fundy on the east coast of Canada

The first phase consists of a 420kw PLAT-I tidal energy platform, and Norway-based Seasystems has been commissioned to supply adjustable mooring tensioners. Lying on the seabed, these are attached to the anchors that hold the power station in place in the strong tidal current – connecting the anchor chains with the anchors.

Seasystems MD, Torkjell Lisland, said: “This is the first mooring contract we (have) secured within floating tidal power, representing an important breakthrough for the company.”

Teaming up with Swift Anchors

Seasystems has joined forces with Swift Anchors, a division of Sustainable Marine, in developing a unique hybrid mooring connector and anchor solution, specifically targeting wave, tidal, floating wind, floating solar, ocean thermal energy conversion, deep water aquaculture and other challenging anchor applications. This new solution, applied to the Pempa’q project, involves the integration of Seasystems’ adjustable mooring tensioners with Swift Anchors’ broad anchor product portfolio – including groutless rock Anchors, screw anchors, drag embedment anchors and grouted self-drilling piles.

When completed, the project will provide up to 9MW of electricity to the province’s power grid. This is enough to power around 3,000 homes and will reduce greenhouse gas emissions by 17,000 tonnes of CO2 annually.

DNV’s Energy Transition Outlook, now in its fifth year and launched two months before COP26 takes place in Glasgow, provides an independent forecast of developments in the global energy system to 2050.

Electrification is on course to double in size within a generation and renewables are already the most competitive source of new power however, DNV’s forecast shows global emissions will reduce only 9% by 2030, with the 1.5˚C carbon budget agreed by global economies emptied by then.

Hydrogen is the energy carrier that holds the highest potential to tackle hard to abate emissions however, DNV’s forecast indicates hydrogen only starting to scale from the mid-2030s and, even then, only building to 5% of the energy mix by 2050.

“Extraordinary action will be needed to bring the hydrogen economy into full force earlier”, says DNV’s Group President and CEO Remi Eriksen.

The new technology combines Nagasaki University’s tidal current power generation technology with Kyocera’s IoT technology to collect reliable ocean data.

Prototype buoys can collect a wide range of data on the marine environment using self-generated energy. A pilot program gathered information from 21 sensors, monitoring everything from water temperature and humidity to current direction. Future development may include sensors for temperature-related salinity variation, chlorophyll turbidity, and temperature related variations in dissolved oxygen concentrations, to name a few.

Marine pollution and climate change have become serious societal issues. To solve these issues and help create a more sustainable world, scientists need more reliable ways to monitor and visualize various sea conditions. However, maintaining a stable power supply is a big challenge for continuous data collection at sea. Therefore, Nagasaki University and Kyocera developed the “Energy Harvesting Smart Buoy,” which generates its own electric power for continuous ocean data collection using a tidal-current power generation system in the buoy.

The new Smart Buoy combines tidal-current power generation technology from Nagasaki University and IoT-related technology from Kyocera. In addition, Kyocera has future plans to monitor fisheries and aquaculture, conduct ocean surveys, and more.

Each prototype is equipped with two different tidal-current power generation systems:

SLTT (Small Lens-type Tidal Turbines) – The buoy and power generation are separate, and a diffuser is installed around the turbine. In addition to protecting the turbine, the diffuser has the effect of increasing the flow of water for better power generation.

VTT (Vertical-axis Tidal Turbines) – The power generation element is directly connected to the buoy. Its AI-guided design incorporates a tilted axis to optimize turbine rotation amid heavy ocean swells and waves.
