    Not a huge battery, but great to see flow batts being deployed on a large scale. Hopefully they prove to be viable increasing the range of battery technologies available.

    Bushveld Energy Secures Funding For 3.5 MW Solar PV + 1 MW / 4 MWh Vanadium Redox Flow Battery For Vametco Mine

    Bushveld Minerals Limited, through its 84%-owned energy subsidiary Bushveld Energy Limited, has completed the development and achieved financial closure for a 3.5 MW solar PV plus 1 MW / 4 MWh Vanadium Redox Flow Battery (VRFB) hybrid mini-grid project at Vametco mine, which will operate as a funded independent power producer (“IPP”).

    Nothing new to me, I grew up aware of all the floaters in the sea at Barry Island.

    Floating windfarms could be hosted off Cornwall and Wales, crown estate says

    Floating windfarms could be built off the coasts of Cornwall and Pembrokeshire after the Queen’s property manager identified a clutch of sites in the Celtic Sea that could host them.

    The crown estate, which generates money for the Treasury and the royal family, has published five “areas of search” that will be narrowed into development plots to host wind power generation.

    Once the project development areas have been agreed, they will be offered to businesses through a tender process, which is due to be launched in mid-2023.

    The crown estate hopes these areas will deliver 4 gigawatts of floating offshore wind power by 2035, fuelling almost 4m homes.

    Only a thought, but I checked the maths (I do that sometimes), and the 4m homes figure works at 3,500kWh pa each if the farm operates at a 40% capacity factor. I wonder if over time the 'number of homes' metric will change as demand goes up for heatpumps and BEV's? At the moment I suspect additional demand is balanced by efficiency gains.

    Just like buses, the post below on Oxford's Energy Superhub project also features a Flow battery as part of a Hybrid battery system.
    There has been an awful lot of effort put into renewable schemes within the Oxford area over a number of years leading up to this. They are certainly working hard to show that it is possible to have energy generated and used locally thus reducing stresses on the Grid. Unfortunately there are not sufficiently strong winds locally to power wind turbines so they have had to rely on other options, solar, Sandford Hydro and of course now, battery's too.

    Wärtsilä supplies battery to Pivot Power as part of cutting-edge Energy Superhub Oxford project

    The technology group Wärtsilä has supplied a 50 MW / 50 MWh lithium-ion battery to Pivot Power, part of EDF Renewables, who have developed a cutting-edge hybrid battery site in Oxford, UK. The hybrid battery system, which was officially launched today at the opening of Energy Superhub Oxford (ESO), will play an essential role in the UK’s shift to renewables.

    The hybrid battery combines Wärtsilä’s 50 MW / 50 MWh lithium-ion battery with Invinity’s 2 MW / 5 MWh vanadium-flow battery. The system will be controlled and dispatched by Wärtsilä’s GEMS Digital Energy Platform and optimised by Habitat’s AI-enabled battery trading system, with the project being owned and developed by Pivot Power.

    The hybrid battery is the first of its kind in the UK, designed to fulfil multiple energy storage needs and support the ramp-up of renewable energy required to reach the UK’s targets of 50 GW of offshore wind and 70 GW of solar capacity by the 2030s[1]. It is also the first in the UK to be directly connected to the National Grid’s high-voltage transmission network at the Cowley substation on the outskirts of Oxford., with the UK’s largest flow battery providing a unique overdrive function that allows it to be operated at higher power levels for sustained periods of time.

    The site forms one part of the 41 million GBP Energy Superhub Oxford (ESO) project. ESO integrates energy storage, electric vehicle (EV) charging, low carbon heating, and smart energy management technologies to decarbonise Oxford by 2040 and create a blueprint for other towns and cities to achieve net zero. The hybrid battery system is a short distance from the Redbridge Park and Ride, where the project’s EV charging hub is located, and can provide backup power for the EV charging infrastructure.

    A big Berlin battery is getting closer to completion. It may be storing heat, not leccy, but at 2.6GWh(t), nothing to be sniffed at.

    Vattenfall starts filling up 200MW thermal storage tower in Berlin

    Swedish public utility Vattenfall is about to start filling a 45m-high, 200MW-rated thermal energy storage facility with water in Berlin, Germany.
    He explained that when there is a surplus of wind energy, the power-to-heat system can convert that surplus into heat to be stored in the tank, reducing any need to curtail wind production. The storage tank can also integrate heat from other industrial processes such as the city’s cleaning department or waste heat from waste water.

    Wow, that's some huge tank Mart and storage facility and what a great way to use excess energy rather than curtailing as you've been advocating for years now.
    From the same page I came across another article on battery storage I thought relevant and that being on how it will in future be perceived by authorities making for a simpler and less costly process when setting up such a facility as detailed below.

    Germany finally gives energy storage its own legal definition

    I really don't have an issue with energy being stored as heat as most of the extra winter energy we need is in the form of heat.  It does make me wonder whether heat pumps will be the future for heating or whether some other solution based on long term storage will become the solution in time.

    CfD round 4 results are out, and good news, 7GW* of offshore wind at slightly less than round 3 (£37.35, v's £39.65). These are 2012 baseline prices, so today, around £45, v's the round 3 price ~£48.

    [*Edit - 7GW of offshore wind at a capacity factor of 50%, is roughly equal to 10% of current leccy demand, so a very significant figure considering the CfD's take place roughly every 2yrs. M.]

    Bit disappointed with on-shore wind and PV at £42.47 (0.9GW) & £45.99 (2GW) (again 2012 baseline), hoped for 10%+ cheaper.


    Contracts for Difference Allocation Round 4 results


    Thanks Martyn.  Interesting that onshore wind needs more 'subsidy' than offshore.

    Not sure what the volumes mean in context?

    Current capacity of wind power is of order 25GW?  But we already have a pipeline of projects under previous CFD rounds?  Not sure how big or when for.  Plus google says there is an 88GW pipeline?

    Are wind farms also being built without CFD support?
    I think....
