BESS Projects Represent ‘Encouraging Progress’ in New York Efforts To Replace Dirty And Polluting Peakers

The title of this post, is the same as that of this article on Energy Storage News.

These are the first three paragraphs.

Battery storage is playing an active role in helping New York City retire its fleet of peaker power plants, with around 700MW of its most polluting power generation assets already fully retired.

According to a new report, 4,019MW – about two-thirds of a 6,093MW fleet – has either retired or put in place plans to replace turbines with cleaner technologies since New York adopted its climate goals and environment protection policies in 2019.

In addition to 700MW already retired, around the same amount again is actively being moved towards end of life.

Note.

  1. Just over 6,000 MW seems a lot of extra peaker power, even for a city as large as New York.
  2. But at least over 4 GW has been retired or the plans to replace it with cleaner technologies are in place.
  3. The New Yorkers certainly seem to be getting on with the conversion, with about a GW/per year either retired or planned to do so.

The article says this about batteries.

Battery storage is one of a number of different technologies that can be used to replace peaking capacity. While lithium-ion batteries with 4-hour duration might be the most directly analogous in terms of technical capability to peakers, effectively retiring the power plants could be facilitated with a combination of other resources including rooftop solar, offshore wind and energy efficiency measures.

I find the 4-hour duration interesting, but I suspect the Yanks know what they’re doing.

So if you were going to replace the 240 MW Glanford Brigg power station, which Centrica describe as a peaker station, with energy storage, you’d use a 240 MW/960 MWh battery, if you were working to New York rules.

Batteries in the UK, that I’ve talked about lately include.

Amp Hunterston – 400 MW/800 MWh – 2 hours

Amp Kincardine – 400 MW/800 MWh – 2 hours

  • Carlton Energy Park – 1040 MW/2080 MWh – 2 hours – Close to an 884 MW gas-fired power station.
  • Coalburn – 500 MW/1000 MWh – 2 hours- Close to a 946 MW collection of wind farms.
  • Gateway Energy Centre – 450 MW/900 MWh – 2 hours – Close to an 732 MW gas-fired power station.
  • Normanton Energy Reserve – 500 MW/1000 MWh – 2 hours
  • Richborough Energy Park – 100 MW/100 MWh – 1 hour
  • Spalding Energy Centre – 550 MW/1100 MWh – 2 hours – Close to an 860 MW gas-fired power station.

Note.

  1. The first field is Output/Storage Capacity.
  2. The second field is the duration.
  3. I have assumed Spalding Energy Centre is another two hour duration system, like Gateway Energy Centre, which is also being developed by Intergen.
  4. Two hours seems to be the most common duration for a UK battery.

Adding the batteries up gives a virtual 3940MW/7780MWh battery.

It amazing how they add up to quite large values. But then every little helps!

And these are only the ones I’ve talked about.

Japanese Offshore Wind And Battery Storage Project Begins Commercial Operation

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

On 1 January 2024, JERA and Green Power Investment Corporation (GPI) began commercial operations at the 112 MW Ishikari Bay New Port Offshore Wind Farm in Japan, which they own through Green Power Ishikari GK, a special-purpose corporation (SPC).

The most significant thing about this wind farm, is that it has been designed from Day One to operate with a battery, which is detailed in the last paragraph.

The project also features a battery storage component with 100 MW x 180 MWh of capacity.

Note that the output of the battery is 89 % of that of the wind farm. Is that the ideal ratio between battery and wind farm capacities?

Conclusion

Because of my training, as an Electronics and Control Engineer, I belief that most renewable energy can be smoothed with the adding of a battery.

Do All Wind Turbines Have To Be Similar?

I feel this is a reasonable question to ask.

But do all wind turbines have to look like those in this picture?

Wikipedia lists three main types.

  1. Horizontal Axis – Those in the picture are of this type, as are all the large wind turbines I’ve seen in operation.
  2. Vertical Axis – Wikipedia shows several examples.
  3. Unconventional Types

Recently, I have come across some which would be placed in the last group.

Hybrid Offshore Wind And Wave Energy Systems

This article on the Journal of Physics is entitled Review of Hybrid Offshore Wind and Wave Energy Systems, is a study from serious academics.

This is the abstract.

Hybrid wind wave systems combine offshore wind turbines with wave energy on a shared platform. These systems optimize power production at a single location by harnessing both the wind and the waves. Wave energy is currently at an earlier development stage than offshore wind. Research in this area is focused in wave energy converters being used for platform motion suppression of floating offshore wind turbines. Wave energy converters can passively shelter offshore wind turbines from waves and can also be actively controlled to reduce the system loads. Additionally, a small amount of supplemental power may be generated, which can be used for offshore wind turbine local power needs. There may be future benefits to these hybrid systems, but at this stage wave energy may increase the project cost and risk of offshore wind turbines. Hybrid wind wave system research and development is discussed, with a focus on floating offshore wind turbines. Additionally, two ocean demonstration scale hybrid wind and wave systems are discussed as case studies: the Poseidon Wave and Wind system and the W2Power system. Hybrid wind wave systems show potential to be part of the future of offshore wind energy.

Note.

  1. Wave energy development is at an earlier stage than offshore wind.
  2. Wave energy converters can passively shelter offshore wind turbines from waves and can also be actively controlled to reduce the system loads.
  3. There is more about Poseidon on this page on the Tethys web site.
  4. There is more about W2Power on the Pelagic Power web site.

The last sentence of the abstract is significant and I believe that hybrid offshore wind and wave energy will play a significant part in the future of offshore energy.

Wind Turbines With Added Storage

Critics and cynics of wind power always ask, what happens, when the wind doesn’t blow.

It is generally accepted, that the best thing to do is to pair a wind farm with some form of energy storage.

Technologies and solar and/or wind farms with energy storage are starting to be proposed and/or installed.

More energy storage will be added in the future in or near to wind and solar farms.

Twin Turbines

This document from the Department of Business, Industry and Industrial Strategy lists all the Contracts for Difference Allocation Round 4 results for the supply of zero-carbon electricity.

One of the projects allocated a Contract for Difference, was the 32 MW TwinHub wind turbine, which I wrote about in Hexicon Wins UK’s First Ever CfD Auction For Floating Offshore Wind.

A full scale twin turbine hasn’t been built yet, but it does seem promising and the visualisations are impressive.

Scroll down on the TwinHub home page to see a video.

World Wide Wind

I’ll let the images on the World Wide Wind web site do the talking.

But who would have thought, that contrarotating wind turbines, set at an angle in the sea would work?

This is so unusual, it might just work very well.

Conclusion

There will be other unusual concepts in the future.
