#SeaPower - A Scottish tidal energy company is launching a new round of funding to commericalise its developments in Orkney, as HydroWorld reports.

Scotrenewables has appointed Aberdeen-based financial advisors Simmons & Company International to lead the investment process after successful testing over the last year of its SR2000 2MW floating turbine, built at Harland and Wolff in Belfast.

The grid-connected device has reportedly supplied up to 25% of Orkney’s power demands at times, with recent figures hitting 20MWh per day. HydroWorld has much more HERE.

#RNLI - A collision with a tidal turbine was to blame for the incident that caused the dismasting of a yacht in Strangford Lough on Sunday 9 June.

As reported yesterday on Afloat.ie, Portaferry RNLI's lifeboat crew was dispatched to the stricken yacht in the narrows of Strangford Lough close to the SeaGen water turbine.

The local RNLI press office confirmed that three men and a teenage boy were on board the 37ft yacht at the time - though BBC News says that only three people were rescued, including a child.

The SeaGen installation in Strangford Lough was accredited by Ofgen as Britain's first tidal power plant, as previously reported on Afloat.ie.

Scotland's west coast will be home to the world's largest tidal power facility, it has been announced.
The £40 million (€45.9 million) 10MW tidal array, to be developed by ScottishPower Renewables in the Sound of Islay, will generate power for more than 5,000 homes.
Scottish Cabinet Secretary for Finance John Swinney, who signed off on the deal, described the project as "a milestone in the global development of tidal energy".
"Scotland's seas have unrivalled potential to generate green energy, create new, low carbon jobs, and bring billions of pounds of investment to Scotland," he said.
The project comes in tandem with the consultation process for the Scottish government's National Marine Plan, intended to highlight the best opportunities for investment across all marine industries.

About Electric outboard engines

The direct-drive component in electric outboard engines means that the electric motors are incredibly efficient compared to conventional marine combustion motors, operating with considerably higher torque whilst using less power.

Without any need for gears, cooling systems and moving parts the motors are maintenance free, highly efficient and economic to run.

As a result, electric boat engines are becoming more popular on Irish waters as the world transitions from fossil fuels to green energy.

To date, popular electric engine sizes have been trolling engines typically used by fishermen on lakes.

These marine engines are available in models that can be used in fresh water and sea water, for your boat or kayak.

Electric motors are Ideal for fishermen because they are quiet and create little in the way of disturbance 

Popular electric trolling models range from 30lb thrust to 55lb thrust in a range of shaft lengths.

But use is becoming broader now in 2021 and electric outboard engines are being used on small runabouts and RIBS where electric outboard engine sizes are getting bigger.

Outboard electric engines are economical and environmentally friendly. Battery technology is also improving at a rapid rate meaning they are becoming smaller and lighter and run for longer.

Built in hydro-generation provides alternative recharging options whilst under sail are also options meaning the electric outboard now has a home on the stern on small yachts and dayboats too.

As far back as 2014, Torqeedo owner Jack O'Keefe from Cork Harbour told Afloat readers of his sailing adventures in a Drascombe Coaster dinghy and how after swapping from a petrol version the rewards from his new electric outboard engine are less noise, no smells, more stowage, better sailing performance and a motor that can be started by a small child. But it's still not silent, there's a whine he says here 

Popular brands in Ireland are Torqeedo, ePropulsion, Pulsar and Minn Kota but there are more arriving all the time as the technology advances
