Redt Energy Share Discussion Threads

Islands often want to attract tourism and increase the life-quality of its inhabitants by
getting a "green image" through its energy transformation. This can be seen as not only
a useful energy and environmental but also a good economic strategy.

Roosecote is Younicos lithium-ion technology I believe.

Two questions TW:
1. What's all this about, and why are you apparently slagging yourself off
2. Why are you posting this on this board. Push off.

Back to business: The Sunday Telegraph article is about the Centrica battery storage depot at Roosecote, Cumbria. The article goes on to talk about energy storage in general,and plans by Eon, RWE and GDF Suez, and implies that energy storage will undermine large-scale nuclear. Not much talk about the technology involved, and no mention of flow machines.



Back in August, Energyst webmag gave us this overview of energy storage business, but again no mention of flow machines. Either RedT is way ahead of the game, or its all BS. I hope not the latter as I'm now intending to change my mind and top up tomorrow!

The Age of the Giant Battery Is Almost Upon Us

Sandfire's Degrussa and Rio Tinto's Weipa project have raised attention for solar-diesel hybrid projects at mines in Australia. Two projects and several announcements suggest that the market for solar- and wind-diesel hybrid plants at mine sites is about to take off in Australia. Diesel generators often power remote mines. The total off-grid generation capacity at mines is estimated at 3.9 GW with an annual electricity consumption of 12 TWh. For replacing a large share of diesel fuel by solar and wind, energy storage solutions play an important role. Australia might serve as a prime example for the rest of the world.

crogrids are a hot topic in the power sector, but for years utilities have struggled to devise business models that allow deployment at a larger scale.

Now, new research is targeting how microgrids, typically designed for individual customers, can be standardized for wider adoption and provide benefits to the larger utility grid.

Africa is prioritizing its energy generation and transmission to drive economic growth and job creation, an energy expert from the New Partnership for Africa's Development (NEPAD) said here on Wednesday.

On the sidelines of the Africa Energy Indaba in Johannesburg, Professor Mosad Elmissiry, senior energy advisor of the NEPAD, said that time for talk has passed and the continent is now committed to fast tracking large-scale provision of energy.

"We want to increase people's access to energy and to make the access affordable, secure and reliable. We are focusing on massive infrastructural projects as a faster way to increase access to energy," Elmissiry said.

Have you seen bobby's tweet in reply to that picture scott posted, is it just me who thinks this is bizarre posting on a company's he supposedly holds shares?

Got to say Western Powers offering looks archaic compared with the inside of a RedT unit and looks like a series of shelving with interconnected Lorry Batteries unlike RedT's futuristic look

Interesting read in "Powerlines" (Magazine for Western Power)the title is "An innovative £1 Million project which examines linking battery storage and solar energy with the distribution network is underway in the South West"

In the article it states:

"The battery energy storage system, the first of its kind in the UK, will be embedded at Copley Wood 1.5 megawatt solar park and connected to WPD's 11kV network."

Pictures are included from outside and inside the array and the batteries are imported from China and encased in a shipping container. The cells comprise of Lithium Iron Phosphate which claims to have "improved chemical and thermal stability". The battery will be running until December to give a full year of results and tests.

Vanadium is a soft, silvery gray, ductile transition metal and is the 22nd most abundant element in the Earth's crust. Vanadium in not found by itself, instead it's most often found in chemically combined forms occurring in about 65 different minerals and has been historically mined as a by-product of other mining operations.

According to the U.S. Energy Storage Monitor, energy storage demand, especially at the business and utility scales, will increase ten times in just the next five years.
The Energy Storage Association states that corporate investments in energy storage reached $660 million in the third quarter of 2016.
Fact - A lack of energy storage is the main factor limiting the spread of renewable energy.
Fact - When we can create, and easily access as required huge stores of energy, we will be free from much of our dependence on fossil fuels.
New battery technology, efficient, easily accessible stored energy, is essential to our renewable energy future.

"V-flow batteries are fully containerized, non-flammable, compact, reusable over semi-infinite cycles, discharge 100% of the stored energy and do not degrade for more than 20 years. Unlike solid batteries, like lithium-ion or lead-acid, that begin degrading after a couple of years, V-flow batteries are fully reusable over semi-infinite cycles and do not degrade, giving them a very, very long life." James Conca, The Energy Storage Breakthrough We've Needed

In VFB batteries, these materials are liquid and have different electric charges. Both liquids (V2+/V3+ and VO2+/VO2+) are pumped into a tank. A thin membrane separates the two liquids but the liquids are able to react and an electric current is generated.
Vanadium is used because it can convert back and forth from its various different states which carry different positive charges. The risk of cross contamination is eliminated as only one material is used. They are also safer, as the two liquids don't mix causing a sudden release of energy.

The liquids have an indefinite life, so the replacement costs are low and there are no waste disposal problems. Also, battery life is extended potentially infinitely. By using larger electrolyte storage tanks VFB's can offer almost unlimited energy capacity and they can be left completely discharged for long periods with no ill effects.

Introducing hydrochloric acid into the electrolyte solution almost doubles the storage capacity and enables the system to work over a far greater range of temperatures, from -40°C to +50°C.

Currently traditional clean, green, renewable energy sources are unreliable sources of electricity production. Vanadium's unique properties make it ideal for a new type of batteries that will revolutionize our energy storage systems.
The Vanadium Flow Battery (VFB), given its unlimited storage capacity, long battery life, low maintenance requirements, adaptability and almost non-existent environmental footprint is today's answer to efficiently storing and accessing energy. The stored electricity will reduce our reliance on fossil fuels cutting pollution and CO2 emissions.
Vanadium, and the fact VFB's are the basis for a more efficient, reliable, and cleaner electrical energy market, needs to be on your radar screen.

Best guess December 2016, what it confirms is what it's use is for, it's way out from what Munters says.
