@RonHughes @KeithMcGraw @RonHughes It is true that both Germany and Denmark have high electricity prices: https://1-stromvergleich.com/electricity-prices-europe/
But this has not influences the rate of energy poverty in these countries: https://energytransition.org/2016/08/comparing-energy-poverty-in-germany-with-other-countries/
And it has created a strong... -
@RonHughes Thank you for providing this additional statistics for the participants. Very informative.
One thing that you should consider is that change does not happen overnight. Germany, of course, should take stronger measures to increase the share of renewables in its gross power consumption and reduce its Co2 emission (especially from the transport... -
@DavidSutton Thank you for your feedback. I will consider this for the preparation of our next courses.
-
@RonHughes @KeithMcGraw some companies are already focusing on this. Check fo example Epiroc: https://www.epiroc.com/en-ge/products/loaders-and-trucks/electric-loaders
Their electric machines are about 2-3 times more expensive than diesel-based yellow machines, but the working condition of workers improves a lot and also the mining company do not need to...

Thank you all for your feedback. I consider your comments for the next courses.

Thank you for your comment, I will revise the video for the next release.
Lack of finance in some off-grid regions has been identified as a barrier. But at the same time, in some other countries, the number of financial instruments is increasing and that drives the market forward. -
@KeithMcGraw Sonnen, if I understood correctly, plans to expand its community. So in a residential building, you install a battery and allow them to store electricity when its cheap and use that electricity during peak time.
Time still is needed for further development of this business model in the market. -
@RonHughes @MartinCook @LanceHavell Thank you all for your feedback, I will consider your suggestions for the next course.
-
@RonHughes thanks for your comment and providing the participants with additional information.
I would like to note that in addition to what you said, in both the website and video, Sonnen explains their 'new' business model in very simple words. Oliver Koch says electricity is for free, but he does not say you do not need to pay for other electricity bill... -
@KeithMcGraw No, there are other ways as well. For example, it is also possible to store electricity during low demand when the electricity price is low, and use that stored energy during peak time. But this is possible when dynamic electricity pricing applies in a country.

Anna Darmani replied to Martin Cook
@MartinCook Thank you for your feedback. I will consider it for our next courses. Note that we used the example of li-ion batteries mainly for the sake of simplicity and in order to increase the knowledge of students on the most promising energy storage technology in the market. But I see your point and I will consider it for our future courses.

Anna Darmani replied to Kevin O'Shea
@KevinO'Shea note that the peak demand is different in different countries, but normally is in the afternoon and not in the morning. For example in Sweden, you pay less if you use your dishwasher between 1-3pm. As @RonHughes Ron said, slowly batteries are becoming available in the market to be purchased by private consumers (for example Tesla Power wall). The...

@RafaelMatos you wrote"In raining days, the water that we collected is free, and also the energy from the Sun. We can store this energy at very low cost. ". Could you please explain where do you store the energy of the sun?
-
@KeithMcGraw I completely agree with your comments. EBA aims at encouraging European industries to be sustainable and ethically responsible when entering the battery market! Let's time show us how successful they will be in this regard.
-
Anna Darmani replied to IBNOMER SULIMAN
@RafaelMatos so far most of the things that I have read about Redox flow is written by "they". I think still we need a bit more time before seeing more of Redox flow batteries in the market.
-
As far as I know, in Europe they are also working on new grid lines between different European countries.

Dear Keith, thank you for your comment! We appreciate the feedback.

Dear IBN, thank you for your comment! We appreciate the feedback.

Hopefully, EBA and Northvolt could facilitate/guide the development of similar battery manufacturing facilities in Europe.
-
@RonHughes one thing that often is overlooked by car owners is that (private) vehicle are generally parked 90% of the time. So I agree with you that the charging process could be slow, but it is not that slow if we consider that a car is parked 90% of the time. This 90% of the time actually will provide a good ground for services such as Vehicle2Grid (V2G) and...
-
Through the larger application of batteries (in particular li-ion) we will see more and more recycling facilities entering the market due to 2 reasons: 1) possibly a higher price for Lithium (due to shortage) 2)economy of scale (based on larger number of available li-ions). Both reasons make the establishment of recycling facilities more profitable.

@BisratMechal Energy density is less of an issue since, for grid-scale application of even in battery farms, space is not constrained. Space is a critical parameter when we use batteries in EVs or for example in flats (in big cities).
-
@CarlesSoldado Energy density is less of an issue since, for grid-scale application of even in battery farms, space is not constrained.
-
@MahsaAzarnia this could be true for very specific cases. But for the majority of grid-scale battery applications, energy capacity thereby battery size is not a big issue.
-
We will go through this topic more in the off-grid application of battery storage.
-
@MahsaAzarnia let me give you an example. At the moment in Europe, it is not possible for distribution or transmission companies to provide cost revenue services using batteries. For example, they can not themselves store electricity when it is cheap and provide it to the market when is more expensive. If such a business model becomes feasible, this will change the...

Anna Darmani replied to Steve Mayers
@SteveMayers Probably you are not familiar with Flow Batteries because they are fairly new therefore their application in the market has been more limited than others (e.g., li-ion or lead acid). I think we will have more flow batteries in the future market and you will hear more often about them. They will be used in applications for which space is not an...

Dear @MariaVivian , thank you for your comment! We are glad you like the course and you are welcome to come back to future courses.
-
@IBNOMERSULIMAN I will look at these two technologies (capacitors and batteries) more as complementary technologies, rather one is being a substitute for another.
-
Dear @MartinCook , thank you for your comment! I appreciate the feedback and will take it under consideration for future courses.
-
Dear @KeithMcGraw, thank you for your comment! We appreciate the feedback and we will try to put this information available online.
-
@JoãoFigueira Thank you for your comment! This course is focusing mainly on batteries and storage technologies utilised for the electricity market. I really appreciate your comments and would hopefully make this point clear in the future courses.
-
@EdwardWright Thank you for your comment! We appreciate the feedback and will take it under consideration for future courses.
-
Anna Darmani replied to Maria Vivian
The cost of batteries has been reduced significantly over the past years. And hopefully very soon will be affordable for everyone.
-
In the next lessons, we discuss further dynamic tariffs which you are referring to. This is a powerful tool and hopefully will be introduced to the energy market soon.
-
Anna Darmani replied to Rafael Matos
@RafaelMatos I hope after this course you understand better that there have been huge improvements in the battery technologies. I do not agree that at the moment all types of battery technologies are expensive, toxic and bulky! Happy to discuss this with you further.

Anna Darmani replied to Andres ALFARO
@AndresALFARO EBA is planning to reduce EU dependency on countries such as China or Japan. They are planning to do so through establishing a strong value chain in Europe, from raw materials to cell production and packages. Although most of the raw material sources are outside of Europe, still there are huge sources are available within Europe. But we are not...

Dear Peter, as Martin said this was implicit in point 4. But this will be further answered in the next video on Grid-scale application of battery storage. Hopefully, that video makes this topic more clear for you.

Dear Roberto, thank you for your comment! We are glad you like the course and you are welcome to our next courses.

Dear Martin, thank you for your comment! We are glad you like the course and you are welcome to our next courses.

Storage size is not an issue due to the availability of rural areas. Storage price, on the other hand, could be an issue, especially if we also consider the cost of connecting the storage facilities to cities and villages using the grid.
-
Hi Vinay, then we should search for an ideal option, no?
-
Hi Andy, I believe you mean to ask industry (for example for melting bottles) for demand response. This would be possible only if there is a financial justification for doing so.
-
Hi Ron, Thank you for your informative comment!
-
Hi Steven, another option is improving the connection to the neighbouring markets (countries). In this way, we can export excess CLEAN energy and still earn money.
-
Dear Hugh, as you commented, storage should not be the only and first chosen technology. Correct planning and energy management is key for a successful energy transition.
-
Dear Nigel, Thank you for your comments. I cannot agree more with you.
