Virtual Power Plants: Enphase, Sunverge And LG In The US, Project Symphony In Australia
The title of this post, is the same as that of this article on Energy Storage News.
The article is a good introduction to the concept of a virtual power plant. The Wikipedia entry starts with this definition.
A virtual power plant (VPP) is a cloud-based distributed power plant that aggregates the capacities of heterogeneous distributed energy resources (DER) for the purposes of enhancing power generation, as well as trading or selling power on the electricity market.
It can almost be thought of as an energy equivalent of the Internet.
As a Control Engineer, I believe that the creation of virtual power plants will be very important in the future.
Read the article and the Wikipedia entry and see if you agree.
EMEC And Gravitricity Pick Up Scottish Green Energy Awards
The title of this post, is the same as this article on renews.biz.
These are the first two paragraphs.
The European Marine Energy Centre (EMEC), energy storage innovator Gravitricity and Crown Estate Scotland were among the winners announced last night at the Scottish Green Energy Awards in Edinburgh.
EMEC won the Champion of Renewables award for its ocean energy test facility, while Gravitricity’s energy storage system, which uses excess electricity to winch weights to charge the system and then releases these when energy is required, was announced as the Best Innovation winner.
I am pleased, as I own a small part of Gravitricity, which I contributed through crowdfunding.
Energy Dome Secures Funding, Partner For New CO2 Energy Storage Projects
The title of this post is the same as that of this article on Renewables Now.
This is the first paragraph.
Energy Dome SpA announced on Tuesday that it has closed a funding round securing USD 11 million (EUR 9.7m) to finalise the construction of a demonstration 2.5-MW/4-MWh carbon dioxide (CO2) battery storage project in Sardinia and to speed up business growth.
Note.
- It appears that Energy Dome has weaponised carbon dioxide against climate change.
- Providing 2.5 MW for over an hour and a half is an impressive performance.
- I think this project has the style we associate with Italy and Italians.
I have found their website at energydome.com and behind their energy storage system is unusual technology.
Their web site says this about their choice of storage medium.
CO2 is the perfect fluid to store energy cost effectively in a closed thermodynamic process as it is one of the few gases that can be condensed and stored as a liquid under pressure at ambient temperature. This allows for high density energy storage without the need to go at extreme cryogenic temperatures.
That is breathtakingly simple!
The main tank for the gaseous carbon dioxide is an inflatable dome and the liquid carbon dioxide is stored in steel tanks.
A turbine -compressor moves the carbon dioxide between gaseous and liquid states storing it appropriately.
It is very impressive! And I suspect extremely affordable!
1.5GW Of Irish PV To Receive Grid Connection Offers Through ECP Process
The title of this post is the same as that of this article on Solar Power Portal.
Note.
- There are 85 projects in total.
- Several also involve energy storage
- Gresham House and Gore Street Energy Storage Funds are involved.
It all seems to be happening in Ireland.
Gravitricity Explores Czech Coal Mine For MW-Scale Storage
The title of this post, is the same as that as this article on renews.biz.
This is the first paragraph.
Scottish energy storage outfit Gravitricity is exploring the potential to transform a former Czech coal mine into an energy storage plant with a capacity of up to 8MW.
It all sounds like a good use for a disused coal mine.
According to the article, future systems with multiple weights could store up to 25 MWh.
Fortescue Unveils Green Investment Framework
The title of this post, is the same as that of this article on Mining Weekly.
This is the first paragraph.
Iron-ore major Fortescue Metals this week launched its Sustainability Financing Framework, enabling the future issuance of green and social debt instruments that will support investments in eligible green and social projects.
I have to admit, that I thought something like this might happen, after seeing all the Fortescue Future Industries publicity on a bus, which I wrote about in Green Hydrogen Can Save Us. But Waiting For It Won’t.
I did say this in that post.
Andrew Forrest is intending to get his message across to the City.
But I didn’t take any action.
I can see other companies and investment trusts following Andrew Forrest’s lead.
Harmony Energy Income Trust Eyes IPO To Develop 213.5MW Of Tesla Battery Storage
The title of this post, is the same as that of this article on Solar Power Portal.
The article is a very detailed look at Harmony and their development of energy storage, using Tesla hardware and software.
It also has things to say about the energy storage market in general.
This is a paragraph.
Paul Mason, managing director of the Investment Adviser, said battery energy storage offers exciting growth potential, with an expected requirement of up to 43GW by 2050 from just 1.2GW now.
It is certainly looking that companies like Harmony Energy Income Trust will be important in funding this extreme growth of energy storage.
‘Unique’ Solar-Storage Solution Providers Plot 300MW / 3.6GWh Australia Project
The title of this post, is the same as that of this article on Energy Storage News.
The first two paragraphs outline the system.
A 1,200 hectare site in South Australia has been secured by a developer hoping to use it to build a 300MW solar power site with 3.6GWh of energy storage, based on a novel technology solution.
Europe-headquartered renewables company Photon Energy is working to roll out the technology created by Australian company RayGen. It combines a kind of concentrating solar power (CSP) + solar photovoltaics (PV) hybrid that RayGen calls ‘PV Ultra’, paired to a long-duration energy storage tech dubbed ‘thermal hydro’.
Thermal hydro appears to be an interesting concept, which uses hot and cold water reservoirs to store energy. Electricity is retrieved using a Rankin cycle engine and the claimed roundtrip efficiency is seventy percent.
This power plant might seem to be very futuristic, but a 4MW solar with 3MW / 50MWh of energy storage project is already under construction and should go on-line in the middle of next year.
The developer; Photon Energy hopes to get the giga-plant ready-to-build by the end of 2023.
This concept could be a very useful one, where there is enough sun for concentrating solar power.
Hydrophilic Polymers: The Key To A Green Future
The title of this post, is the same as that of this article on Tech Xplore.
This is the first paragraph.
Researchers from the University of Surrey and the University of Bristol are working on innovative devices to tame and store carbon-free renewable energy from unpredictable sources such as wind and solar.
That got me interested and I read the whole article.
This abstract on SpringerLink gives a definition of hydrophilic polymers.
Hydrophilic polymers are those polymers which dissolve in, or are swollen by, water. Many compounds of major technical and economic importance fall within this definition, including many polymers of natural origin. Many foodstuffs—containing substantial amounts of carbohydrate and protein— can be classified as hydrophilic polymers, and some have important technical and industrial uses, apart from their nutritional value. For example, although over 95% of the starches produced from corn (maize), wheat, potato, tapioca, and other vegetable sources are used as foods (human or animal), the remaining quantity represents an important part of the technical polymer market. In fact, more than two-thirds of hydrophilic or water-soluble polymers used in industry are derived from polymers of natural origin, so coming from renewable resources (harvested crops, trees, waste animal products and so on), rather than petrochemical sources of finite availability.
This paragraph from the Tech Xplore article describes the research.
The Chemistry Department at Surrey is working with collaborators at Bristol, Professors Ian Hamerton and David Fermin, and Superdielectrics Ltd., an innovative British Research Company located at the Surrey Research Park to transform simple hydrophilic polymers which were originally developed for use as contact lenses, to realize a second critical energy storage process.
This could lead to the next generation of supercapacitors.
Conclusion
This is fascinating technology and it could save the world.
