#POWER FROM THE SEA - Martin McAdam of Aquamarine Power talks to The Irish Times about his company's efforts to harness power from the sea.

The Edinburgh-based firm has spent a number of years and some £60 million (€74.5 million) developing its sea surface instruments - using technology researched at Queen's University Belfast - at locations in Scotland, Northern Ireland and the United States.

Most recently, the business has been overseeing the final stages of an underwater base off Orkney to complete testing of its latest wave energy 'harvester' prototype, the Oyster 800.

As previously reported on Afloat.ie, the Oyster 800 can generate an incredible 800 kilowatts by way of a giant hinged flap that juts out of the water.

Each passing wave closes the flap shut like a clamshell, with the resultant hydraulic pressure driving an onshore turbine.

It marks an impressive development, but as McAdam says, the wave energy sector still requires patience from those who provide its funding.

“We need to perfect the technology that we have got," says the Aquamarine chief executive, who adds that the objective is “not revolution anymore, but evolution”.

“We shouldn’t be overambitious," he says. "We should get the technology to a stage where it is robust and cost effective. In 10 years’ time, if we in Scotland have somewhere up to 500MW, then that would be a successful industry.”

New Scientist has highlighted some of the latest technologies being developed to harness power from the sea.
Companies such as Pelamis Wave Power and Aquamarine Power are already testing prototypes of their so-called wave energy 'harvesters' - enormous machines that can capture the massive potential energy stored within ocean waves.
Pelamis' huge P2 is filled with state-of-the-art computers that allow programmers to control and update its operations on the fly, quickly taking advantage of changes in sea conditions to maximise energy production and increase efficiency.
The proof is in the pudding, as P2 can produce 750 kilowatts of power - twice as much as earlier prototypes.
Aquamarine's Oyster 800, meanwhile, can generate an incredible 800 kilowatts by way of a giant hinged flap that juts out of the water. Each passing wave closes the flap shut like a clamshell, with the resultant hydraulic pressure driving an onshore turbine.
"If you can get that sort of level of performance improvement then the economics suddenly start to look a lot more favourable," says The Carbon Trust's Stephen Wyatt.

Marine Leisure & Aquatic Tourism

Domestic coastal tourism expenditure was approximately €698 million in 2018, while domestic marine tourism generated €381 million.

Activities such as walking/ running along the coast, swimming and beach visitations are among the most popular activities for domestic visitors on both day and overnight trips.

While participation rates in pursuits such as bird and wildlife watching in coastal areas and visiting nature reserves, etc. in coastal areas were lower, these activities did see the highest frequency of both day and overnight trips for those active in these activities. 

According to the National University of Galway (NUIG) research the average expenditure per coastal day trip in 2018 was calculated at €95. The equivalent for coastal overnight trips was €310. The estimated water-based activity expenditure per person per trip across the sample was €56 rising to €73 for the subsample that actually undertake waterbased activities on their coastal visits. The results also indicate that domestic tourists undertake the majority of their marine activities on the West and South coasts of Ireland and that there are notable differences in participation rates across age groupings, social classes and by family makeup.

A domestic tourist is defined in this report as a person who spends at least one night away from home on their trip. Total expenditure by domestic tourists in coastal areas was estimated to be €698 million in 2018, which represents 35% of the total expenditure by domestic tourists (using the broader Fáilte Ireland measure for domestic tourists that includes business trips equating to 10.92 million in total trips and €2,006 million in total revenue).

The marine-related activity expenditure, or what might truly be referred to as domestic marine tourism, is estimated to generate revenue of €381 million with €172 million being spent on water-based activities. Marine tourism makes up an estimated 19% of total domestic tourism expenditure.

Marine Leisure Tourism - FAQ

Coastal tourism refers to land-based and water-based tourism activities taking place on the coast for which the proximity to the sea is a condition including also their respective services. Coastal and Marine Tourism & Leisure are seen as one of the Blue Economy (BE) sectors that can help unlock the potential of multi-use of space at sea by engaging with Blue Growth (BG) sectors such as Aquaculture and Marine Renewable Energy among others.

Sports: sailing, surfing, diving and fishing Heritage: Unesco coastal villages, archaeological sites of interest, biospheres and historical points of interest Arts: coastal museums, art galleries, museums, wrecks Education: Eco-tourism, field courses, NGOs. Food: Seafood restaurants, Seafood festivals

NUI Galway carried out a survey of domestic residents in Ireland in 2019 as part of a survey entitled "Valuing and understanding the dynamics of Ireland's Ocean Economy". The purpose of the household survey was to profile the domestic market for single-day trips (leisure) and overnight trips (tourism) for coastal and marine-related activities in Ireland. The results of the survey are also used to estimate what proportion of an Irish resident's total domestic tourism expenditure is in coastal areas (coastal tourism) and what proportion is spent on undertaking marine-related activities (marine tourism).

The NUI results highlight the important contribution that Ireland's marine and coastal resources make to the leisure experiences of the general population and the importance of the domestic tourism market to local coastal economies. The analysis indicates that domestic coastal tourism expenditure was approximately €698 million in 2018, while domestic marine tourism generated €381 million. Activities such as walking/ running along the coast, swimming and beach visitations are among the most popular activities for domestic visitors on both day and overnight trips. While participation rates in pursuits such as bird and wildlife watching in coastal areas and visiting nature reserves, etc. in coastal areas were lower, these activities did see the highest frequency of both day and overnight trips for those active in these activities. Satisfaction with the available marine-related leisure facilities was also found to be very high across all activities.
