    Impressive photo:
    Does anyone recognise the used EV batteries?
    If those are 24kWh Nissal Leaf batteries, that's 432kWh of storage. (Even if degraded by 25%, as stated in the article, it's still 324kWh.)

    Interesting thing is that used leaf 24kwh battery packs cost about £4k or £200 per kwh assuming they still have 20kwh useable which is supposedly more than car makers are getting new packs for at the pack level and presumably way more than it costs for Telsa megapacks for example....
    I think....

    What a great scheme Vattenfall have proposed below. Let's hope it becomes a reality in the fullness of time.

    Vattenfall eyes hybrid wind, solar and storage development in Mid Wales

    Vattenfall is eying the development of a renewable energy scheme at Mynydd Lluest y Graig in Mid Wales.

    The Swedish multinational is considering a range of technologies for the site, including solar panels, energy storage and wind turbine options.

    Plans for the site in north Powys between the villages of Talerddig and Llanerfyl were previously shelved in 2013 due to regulatory changes in Britain, but given technological advancements the company has decided to look at the site afresh.

    “We’re looking forward to talking to the local community about this renewable energy scheme and seeing what the full potential of the project could be,” said Jonathan Hewett, Vattenfall’s project manager for the scheme.

    “The amount of investment planned through this scheme could be transformative – supporting communities at a grass roots level to reduce their energy bills, invest in the local economy over the long term and build a real benefit from hosting the project.”

    Hiya CW, I've gone off on a tangent (again), but the dates stand out for me, an earlier proposal in 2013, and now 2022. Back in 2013 I assume, and of course that may be unfair, that the default position by many locals would have been negative, due to fears and concerns over wind turbines, and change in general. A totally natural and understandable initial reaction. But now, folk are probably far more positive, having seen the rollout of PV and wind, and also more supportive of green generation.

    Nothing really to do with the scheme you've posted, just a general thought provoked by the article, and the positive transition over the last decade.

    Have to agree there Mart, It will certainly be interesting to see what reception the affected communities offer. Given how fuel poverty is being mitigated by the generation of energy from Graig Fatha and rising energy costs perhaps they will get a warmer welcome now. We can but hope!

    For those with an interest in CfD Allocation Round 4, the "sealed bid window" closed on the 16th of June.
    We're currently in the "allocation and audit" phase, and the winning bidders are dut to be announced on the 7-8 July, roughly a fortnight from now.

    Didn't we address this one a couple of weeks' ago?

    In terms of capacity and distance this mammoth scale project has cleared another hurdle along the way. Financial close is anticipated by early '24 with delivery of energy to Darwin in '27 and Singapore '29. While the panels will cover an area of some fifty sq miles it amounts to no more than 0.002% of Australian land mass suggesting there is considerable potential for similar schemes both here and elsewhere on our planet.

    Sun Cable project secures support of Infrastructure Australia

    Sun Cable’s massive AUD 30 billion ($20.7 billion) Australia-Asia PowerLink project has passed another major milestone by obtaining approval from Infrastructure Australia.

    You've done it again CW and sent me off on a ponder. Two things - I wonder if any progress on this scheme helps to bolster confidence in the Morocco to UK scheme and vice versa, presumably can't do any harm. And secondly I was thinking about all of that desert land with PV. Presumably some shade will help the local flora and fauna, a bit like wildflowers and pollinators benefit from PV over grass in the UK. Assuming of course that the 'disruption' is beneficial to a desert environment, and how desirable a desert is.

    [Just done a quick bit of Googling on deserts:

    A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation.

    Denudation is the name for the processes of erosion, leaching, stripping, and reducing the mainland due to removal of material from higher to lower areas like valleys, river valleys, lakes and seas with a permanent filling of low lands.]

    Article on the amount of energy storage that Europe will need going forward. Things may have changed, but I think the estimate for the UK is ~20GW by 2030. Note that around a third of the stated 2030 target for Europe of 187GW comes from existing PHS (pumped hydro storage). The article also provides a breakdown by type of how that storage may be provided.

    I may have missed it, but I'm not sure if overcapacity is included, as that's an easy first option for expanding RE penetration, and as generation costs fall, so does the cost of spill/waste/curtailment. Perhaps this 'spills' over into some of the large seasonal solutions mentioned.

    Europe needs 600GW of energy storage by 2050, says trade body EASE

    Europe will need a total of 187GW of energy storage by 2030 and 600GW by 2050 to meet its renewable energy targets, according to the European Association of Energy Storage (EASE).

    The 2030 figure was first published last month while the target for 2050, when the continent’s renewable mix is expected to reach 85%, is an entirely new forecast. The 600GW is part of a total of 811GW of flexibility capacity needed, with the rest made up of gas turbines.

    Of the 187GW, 65GW will be pumped hydro energy storage (mostly already existing today), 67GW of battery storage and other short duration solutions, and 55GW of energy storage from longer-duration batteries and other energy storage solutions.

    The organisation said that storage uptake on the continent is lagging behind renewable energy resource and that the EU risks being unable to integrate new renewable energy resources. As reported in last week’s webinar conducted by research firm Delta-EE in collaboration with EASE, covered by Energy-Storage.news, deployment needs to ramp up to 14GW a year to hit the 2030 goal.
