Thanks all . Really great to hear that JV is using the info constructively.

sorry - thought first post hadnt worked

I posted yesterday that I had contacted Storen about the taken-down article. Detailed response below:
thanks for your email.When we refer to cycles, we refer to Equivalent Full Cycles. Many factors influence the total number of cycles of lithium batteries, the main one being Depth of Discharge. If I discharge the battery at 20% DoD, rather than at 100%, we would increase the total number of cycles. At the same time, we would be using only 20% of the nominal battery capacity.  If we limit the DoD, the total number of cycles will grow. If we look at warranties of lithium batteries, Powerwall included, they often introduce the concept of maximum throughput, that is the maximum number of MWh that are covered by the warranty. The US Powerwall warranty is:   >Solar self-consumption/ backup only - 70% at 10 years following initial installation - Unlimited cycles (comment: offering unlimited cycles is meaningless generosity. With solar, people cycle once per day, they charge during the day and they discharge at night, so it equates to 3,650 cycles in 10 years).   Any other application or combination of applications  - 70% at 10 years following initial installation date - 37.8MWh of aggregate throughput (comment: in this scenario you may cycle more than once per day, but Tesla limit the aggregate throughput).Furthermore, if the battery loses say 30% capacity in 10years, over the period I will have only an average of 85% of the minimal capacity that is usable. So the price/kWh should be adjusted accordingly given that the customer pays for capacity that is in fact lost over time. The calculation is Adjusted Cost/kWh / number of expected Equivalent Full Cycles. In the first example above, solar, it would be 3,650 cycles. In the second example, it would be Max Throughput 37,800kWh / 13.5kWh capacity = number of EFCs, then Adjusted cost/kWh / number of EFCs cycles. Thanks for your words of support. I have sent Cleantechnica all relevant information and we are discussing republishing of the article.

Thanks all for comments. Much appreciated. Nod to Alfa for number to text which prompted me!

....astonishing how many of my friends were listening to R2. I've had quite a lot of responses!

Well, stunned. I texted JV on the number Alfa gave ...and amazed that they phoned me back for a comment. Liverpool Carnegie Road should have hit National headlines , so good to put it out to a wider audience especially as Pivot have gone for a predominantly Li model.

me!

Dear Sirs , I have just read the article on VRFBs that you had published but just pulled after an intervention by Elon Musk who is supporting a rival lithium based technology.

Your article is broadly correct about the degredation of lithium batteries , although I am unable to comment on the figures you use on cost per cycle.

You do not mention the risk of fire in lithium batteries – there are videos of several Tesla vehicles burning furiously and in the UK we have just had a major fire at a newly commissioned lithium battery storage unit in the centre of Liverpool (Carnegie Road).

Negligible fire risk is a further HUGE advantage of VRFBs. The gases released in lithium battery fires include Hydrogen Fluoride which is exceptionally dangerous and toxic to the health of firefighters (see Larsson https://www.nature.com/articles/s41598-017-09784-z). For this reason , a number of authorities have banned the deployment of lithium battery technology.

I hope you will stand by the facts in your article. The future is vanadium despite what Elon might try.

Well, I lay awake last night reflecting sadly on the bad decisions I've made around this share. I bought in at 1.5p in 2013 but then continued to buy as I believed in the story right up to 48p and my average of well over 7 figure shareholding is 14p. I was not alone in thinking this would be well past 100p by now as many dozens of investors on this board guessed at the date this would be reached and every single one of them has been wrong. We were all done by the SP rocketing on the back of a brief and poorly understood spike in the price of Vanadium which shows no sign of recovering even 2 years later , and where even the increase in V demand from VRFBs can seemingly be met at rock bottom prices . So, when I look back, it's clear that I was greedy. I had the opportunity to sell at a profit but didn't. So, I would very definitely sell at 50p if that was offered .

No, I meant kidding about not wanting a bid hostile or otherwise. Bring it on. Whether successful or not it would relate us pronto.

Are you kidding Libero?

Mogwhy, can I ask where you found this - i hadnt seen it. Its a little unusual in that there seem to be 2 sets of 30 voting shares. Setting up the distinct possibility of standoffs if different views are taken. Where is the casting vote?

...FT....hold for another 5 and you'll get an ide of how I feel...

So, securing funding for huge expansion at favourable rates added £0 to the value....yeah, right

...don't know about anyone else, but I'm getting close to the end of mine......

100% correct there Sanchez. We need the buzz to convert to LTHs in for a couple of years to take advantage of 200 ( or even ??2000) % rises. Rather than swing traders out with their 10%.

DBB: best post for ages. Laughed out loud!!

Are you reading the same RNS as the rest of us Libero:

Duferco Participations Holding S.A., has agreed to accept an early repayment of US$11.5 million of their US$23 million convertible loan notes issued in accordance with the terms of acquisition announced on 23 October 2019. US$6.5 million will be repaid through the issue of new Bushveld shares and US$5 million of the loan notes, plus interest of US$1.15 million will be settled as a cash payment.
Half is being repaid by new share issue.

..these RNSs. I think FM would have liked to pay cash to Duferco for full amount but has been prevented from doing so by low V price and CV affecting profitability short term . However Orion obviously like what they see. Going to be interesting to see how markets react.
