Pumped Hydro Storage Proposal for Loch Ness

Urquhart Castle, Loch Ness

400 MW, 2.4 GWh pumped hydro storage plant proposed for Loch Ness by ILI Energy, enough to power 400,000 households for 6 hours. Scotland has 2.4 million households and in 2017 69% of its electricity generating capacity was renewable, mostly wind. By 2020 this share is expected to be increased to the full 100%.

Britain Rules the Waves of Offshore Wind

This graph depicts the total amount of offshore wind projects that are “in the pipeline”, a branch of sport dominated by Europeans, who are lucky to own large, shallow water tables in the North Sea, Irish Sea and Baltic Sea, with excellent wind speeds (>10 m/s average). These 600,000 km2 combined have the potential to supply the entire EU with clean electricity three times the current consumption. Currently the British are adopting wind energy at a breath-taking speed, pun intended, although the developers and equipment producers are mainly continental Europeans, that is Danish, Germans, Dutch, Norwegians, Swedish, whose industries are growing rapidly and have the potential to become the successors of the Anglo Seven Sisters oil giants of the 20th century.

Dockwise Used to Transport Windfarm Jackets From Gulf

Offshore wind moving into the area formerly reserved for giant oil platforms only. The world’s largest heavy lifting vessel Dockwise Vanguard of the Dutch based Boskalis was used to transport 36 jackets from Lamprell’s construction yard in Jebel Ali to Vlissingen, from where they will eventually be installed in the 714 MW East-Anglia ONE offshore wind farm. Partners: ScottishPower Renewables (developer), Boskalis & van Oord (logistics), Lamprell (jackets), Siemens (102 x 7 MW turbines + rotor blades).

Gravitricity

Dutch-British project involving storing/retrieving electricity by lifting/sinking large weights in a mine shaft (59,000 of those in the UK alone). Claim made by startup “Gravitricity”: power up to 20 MW per installation, life span ±50 year and a storage efficiency of 80 à 90%.

MeyGen Tidal Power

MeyGen is the worlds largest tidal energy plant which is currently in construction. The project uses four 1.5 MW turbines with 16m rotor diameter turbines submerged on the seabed. The project is owned and run by Tidal Power Scotland Limited and Scottish Enterprise. The high speed of currents in the area, reaching up to 5 metres per second (11 mph), made the chosen site in the Pentland Firth well suited to this type of energy generation… In December 2016 it was announced that the first turbine had begun full power operations, and all four turbines were installed by February 2017. Atlantis plans for 400 MW.

World-Record Pumped-Hydro Storage for Scotland?

An anonymous energy blogger named “Scottish Scientist” has posted a proposal for a giant pumped hydro storage facility in the Scottish Highlands with the potential to service most of Europe.

The numbers are massive:

Height dam: 300 meter
Width dam: 2,000 meter
Max. water elevation: 650 meter
Storage volume: 4.4 billion m3
Lake surface area: 40 km2
Energy content: 6,800 GWh or 283 GW days

The new storage facility would have “enough capacity to balance and back-up the intermittent renewable energy generators such as wind and solar power now in use for the whole of Europe!”

If one “limits” the area to a circle with a radius of 3,000 km and applies 800 kW transmission lines, a two-way storage efficiency of 79% could be achieved. However, if limited to the North Sea area, one-way losses could be reduced to 7%.

The proposed design would includ a “stepped-canal solution”, see picture above. The biggest cost would be building a large canal of 170 meter width, which would require to move more earth than in the Panama Canal project to allow for discharging water speeds of 10-11 m/s.

Green Light Swansea Bay Tidal Power Station?

A UK government commission under former energy cabinet minister Charles Hendry has advised to go ahead with a 320 MW tidal energy project in Swansea Bay, Wales.
The British industry may have missed the boat with wind energy manufacturing, here is a chance to lay a claim on becoming a leader in tidal power.

#BritanniaRulesTheWaves

Three largest operational tidal power plants:

  1. Sihwa Lake Tidal Power Station, South Korea – 254MW
  2. La Rance Tidal Power Plant, France – 240MW
  3. Annapolis Royal Generating Station, Canada – 20MW

Liquid Air Energy Storage

[source]

Core idea: freeze air with excess renewable electricity for storage purposes and when you need electricity, warm the liquid air with heat from the environment and as such create high pressure air that can be used to drive a generator. Advantage: scalability, mature technology, low cost, high lifespan, possibility to include waste heat (for instance from powerstations) to increase efficiency. 50 MWh typical storage volume (“entry level”).

Round-trip efficiency:

In isolation the process is only 25% efficient, but this is greatly increased (to around 50%) when used with a low-grade cold store, such as a large gravel bed, to capture the cold generated by evaporating the cryogen. The cold is re-used during the next refrigeration cycle. Efficiency is further increased when used in conjunction with a power plant or other source of low-grade heat that would otherwise be lost to the atmosphere. Highview Power Storage claims an AC to AC round-trip efficiency of 70%, by using an otherwise waste heat source at 115 °C. The IMechE (Institution of Mechanical Engineers) agrees that these estimates for a commercial-scale plant are realistic. However this number was not checked or confirmed by independent professional institutions.

Scotland E-Vehicle Country by 2032

The quiet streets of Edinburgh in the late thirties.

The Scottish government has pledged to phase out new petrol and diesel cars and vans across Scotland by 2032, eight years ahead of the UK Government target. Nicola Sturgeon outlined plans to “massively expand” charging points and set up pilot projects to encourage uptake of electric vehicles.

Comment: Scotland can afford it, now that it every now and then produces more than 100% of its electricity needs from renewable power.

2050 – An Energetic Odyssee

Fascinating English-spoken video of Dutch origin [*], with graphics illustrating the energy policy of the European Union for 2050 (of which Britain will no longer be a part after Brexit). Core of solving the energy and climate problems are 25,000 10 MW offshore turbines that will provide the countries bordering the North Sea with 90% of its electricity needs and leaving ample additional capacity potential to provide the rest of Europe with energy as well, in the form of electricity or hydrogen.
