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.

DONG to Build World’s Largest Offshore Wind Park Hornsea-UK

DONG Energy of Denmark has won the bid for building the largest offshore wind park to date (1.4 GW), Hornsea-2 in the British part of the North Sea at a record low price guarantee of £57.50/MWh and is scheduled for completion in 2022. DONG is currently working on Hornsea-1 (1.2 GW), to be completed in 2020.

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.

European North Sea Energy Alliance

The old and near obsolete North Sea oil & gas infrastructure can be reused for the coming reneweable energy base, where the North Sea will play a central role. Core themes ENSEA:

Energy system: The infrastructure and processes that deliver power to end users and includes the electricity and gas supply networks, power generators (both large and centralised land small and decentralised) and other assets.

Balancing: Regulation of energy production, storage and consumption in order to equalise the production and consumption at any time (e.g. by quick regulating gas power plants) to keep the electrical energy system secure.

Back up: Energy production capacity which is in standby to react quickly when there is a difference in energy production and consumption e.g. because of fluctuating production of renewable energy sources like wind and solar energy.

Storage: Small capacity storage and high power pumps (e.g. flywheels or batteries) capable for operating for minutes or hours, or larger capacity storage necessary for extended periods without production from renewable sources.

Infrastructure (electricity grid): Smart grid infrastructures designed for both supply to customers as well as production of power within these grids.

[wikipedia.org] – Sabatier reaction

CO2 + 4H2 → CH4 + 2H2O   ∆H = −165.0 kJ/mol

Hydrogen can be won from water and electrolysis, using renewable electricity. Hydrogen is explosive and needs to be stored at very low temperatures. By mixing it with the superfluous greenhouse gas CO2 (an exothermic reaction, meaning you get extra heat), you get methane, which is far easier to handle. And you solve the storage problem.

3 x 1.2 GW Wind Parks to be Built in Spain and Britain

[source] La Mancha, Don Quixote and Windmills. Nobody fighting the Spanish wind mills this time around.

The wind is blowing in the right direction for the European wind industry these days. 3 giant 1.2 GW wind projects have been given the green light, one Spanish onshore in North-East Aragon and two offshore in the North Sea off the coast of England: Hornsea I and East Anglia III, the first with 7MW Siemens wind turbines. The British projects are supposed to be completed by 2020 and 2025 respectively.

Scotlands Generates 124% Wind Electricity Jan-Jun-2017

Statoil of Norway busy constructing floating wind turbines for the Scottish Hywind projects.

Scotland makes impressive progress with installing renewable power. During the first half of 2017 124% of Scotland’s electricity needs were met from wind power alone. According to a report, Scotland could be fossil-free by 2030.

Hywind Scotland Floating Wind Turbines Pilot Completed

A small 30 MW wind farm has been completed in the waters of Stord, Norway and will be towed to Scotland. The project consists of five 6 MW wind turbines. What makes the project unique is that the turbines are floating, ensuring that shallow water is no longer necessary for offshore wind to work.

Van Oord to Build East-Anglia Wind Farm Foundation

Van Oord has been awarded the contract for East Anglia ONE offshore windfarm by ScottishPower Renewables (part of the Iberdrola Group) for the transport and installation of 102 three-legged jacket foundations. This is the largest amount of three-legged foundations in a wind farm ever installed worldwide. The East Anglia ONE offshore windfarm is located in the southern North Sea, 45 kilometers southeast of the town of Lowestoft, United Kingdom. The offshore wind farm will have 102 Siemens 7 MW wind turbines, with a total capacity of 714 MW. Once operational in 2020, the offshore wind farm will deliver sustainable energy to 500,000 households.

Van Oord will be responsible for the logistics of all jacket foundations and piles, sourced from various suppliers, and the transport to the marshalling port of Flushing in The Netherlands. From there the foundations will be transported and installed with an installation vessel. The installation work is planned between half of April 2018 and the end of October 2018.

Walney Extension Wind Farm Irish Sea Under Construction

The Walney 367 MW 102 wind turbine wind farm is one of the largest offshore wind farms in the world today. The construction of an extension is now under way to be carried out by Dong Energy of Denmark, which will add new very large turbines: 40 8MW Vestas V164 for Phase 1 and 47 7MW Siemens gearless turbine for Phase 2. Together this will constitute 660 MW name plate capacity.

If you install the MarineTraffic app on your iOS device and add the Van Oord installation vessel Aeolus to your fleet of favorites, you will receive an email every 2-3 days, indicating that the Aeolus has arrived again in Belfast to pick up yet another load of four monopiles to be rammed into the floor of the Irish Sea. The turbines will be installed by the Seajacks Scylla.
