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.

French hydrogen producer Lhyfe said its plant in Bouin (Vendée), France is now producing the first renewable green hydrogen in the world made using an electrolyser powered directly by wind turbines, and in industrial quantities (up to a tonne a day).

Matthieu Guesné, CEO and founder of LHyfe, said: “A year after laying the foundation stone, we are extremely proud to be launching this site, which is symbolic of course for us, but also for what it represents for energy transition. Our gratitude goes to our five initial partners, who have made this “mad” project to change our energy model possible. Now we have succeeded this first step, we are ready to move faster.”

Volume to ramp up

The site currently produces 300kg a day, but will ramp up to a tonne a day in the coming months. Lhyfe’s hydrogen will supply four refuelling stations in western France.

Some fifty or so heavy vehicles, buses and refuse collectors will be powered by renewable green hydrogen in Loire-Atlantique, Sarthe, and Vendée at first. Further rollout will happen eunder the VHyGO project in particular.

Lhyfe will soon reveal the names of other operators that it will be supplying, in sectors such haulage, logistics and industry.

Lhyfe’s first R&D centre, adjacent to the production site, is dedicated primarily to optimizing its production process and to offshore development work. It is already prepared to produce hydrogen at sea, through a first renewable hydrogen production demonstrator that will be implemented in a few months off the coast of Loire-Atlantique.

The company has already confirmed around sixty projects throughout Europe. Lhyfe has raised €50m to support Lhyfe’s development in France and abroad, through the strengthening of its teams and the funding of R&D and new projects.

A study, led by Northern Ireland maritime design and applied technologies company Artemis Technologies has been awarded £533,000 to investigate transformative solutions to decarbonise crew transfer vessel (CTV) operations in the offshore wind sector.

The grant, announced at London International Shipping Week, has been awarded as part of the Clean Maritime Demonstration Competition funded by the Department for Transport and delivered in partnership with Innovate UK.

Artemis Technologies, which is also in the process of building two fully electric foiling ferries for Belfast, is partnering with Tidal Transit, an experienced CTV owner and operator; ORE Catapult, a research technology organisation specialising in the offshore renewables sector; and Lloyd’s Register, a globally respected maritime classification society.

It will seek to demonstrate the transformative power of the revolutionary Artemis eFoilerTM electric propulsion system to drive down carbon emissions in global CTV operations.

Dr Iain Percy OBE, CEO at Artemis Technologies said: “Operating for an average of 250 days a year, crew transfer vessels burn around 1,500 litres of diesel a day. Equating to almost 475,000 tonnes of CO2 emissions across the UK and EU annually, they are a major pollutant.

“With global offshore wind capacity set to soar over the coming decades, including the UK government targeting a four-fold increase by 2030, it is imperative that a solution to decarbonise CTV operations is brought to market quickly.

The study will use digital twin technology and include a full mission simulation of an eFoiler propelled CTV undertaking crew transfer operations, as well as provide a regulatory roadmap towards certification of the technology.

Leo Hambro, Commercial Director, Tidal Transit added: “The eFoiler aims to deliver an electric solution that would work even at the most far from shore projects over time and will revolutionise the industry.”

Additionally, the companies are partnering on a £2.8m project led by MJM Power which will test an on-turbine electrical vessel charging system.

Artemis Technologies is also part of the Northern Ireland Green Seas consortium, led by Power NI, which is receiving £398,000 in funding to investigate shore power and hydrogen bunkering solutions.

The AiP was given to Dutch renewable energy company SolarDuck for its offshore floating solar solution ‘King Eider’, designed to help meet zero emission goals.

Koen Burgers, CEO of SolarDuck, said: “Bureau Veritas is a key name in the maritime industry, and well known for their certification of maritime structures. We are immensely grateful for their support and cooperation on certifying our technology and setting standards for the Offshore Floating Solar industry.”

Strong floating structure

Launched in April, SolarDuck’s first pilot ‘King Eider’ consists of four triangular-shaped units, which are mounted by 156 solar panels and deliver a combined electrical output of 64 kWp to the grid. The project was deployed in IJzendoorn, in the Netherlands. The structure holds the solar panels more than three meters above water level. The platform is designed to handle coastal sea conditions and hurricane-force winds. It is also optimised for offshore sites in estuaries, natural harbours, as well as near-shore sites.

Bureau Veritas was involved in the project from the design stage. The AiP covers the design methodology of the unit’s structure and validates the relevant parts against guidance note NI631 on the Certification Scheme for Marine Renewable Energy Technologies, and NI572 on the Classification and certification of floating offshore wind turbines. These guidance notes provide the requirements to certify novel marine renewable energy technologies.

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.
