How energy storage can power global renewables drive

As the consequences of climate change become ever more apparent, investments in renewable energy are seen as crucial to safeguarding the future of the planet.

Renewable sources, including wind, solar and hydroelectric, currently account for about a quarter of global electricity generation – a proportion that is set to increase as part of efforts to decarbonise.

However, the sector still suffers from constraints. The most common criticism of renewables is reliability because output fluctuates according to, for example, the time of day, the weather and, in the case of hydroelectric power, seasonal river flows.

This is where energy storage comes into play. Grid-scale storage involves technologies that are linked to the grid and can send power back into it when necessary.

Pumped-storage-hydropower, where water is pumped into a reservoir and released at another time to generate power, is currently the biggest form of grid-scale storage.

Demand for battery storage is also growing, as scientists are working to devise devices that are more efficient and – crucially – affordable.

Some of that research is taking place in the UAE, as evidenced by a recent announcement by Dubai Water and Electricity Authority (Dewa).

The organisation revealed that it had filed a patent for a chemical liquid said to make energy systems more efficient. The liquid could, Dewa said, be suitable for lithium-ion batteries and fuel cells.

Lithium-ion batteries are among the most important methods of short-term energy storage. They typically last up to a few hours, and can level out demand on the power grid.

As renewable energy ramps up and electric cars (which typically use lithium-ion batteries) are manufactured in ever-greater numbers, demand for lithium is on an upwards trajectory – so what is getting in the way of producing enough?

“From the point of view of technology, there’s actually no reason nowadays to not implement 100 per cent renewable,” Prof Fabio La Mantia, who works on energy storage and conversion at the University of Bremen in Germany, said.

“The limitation is how much do you need? Where will we find all the materials? And how much do we have to pay for 100 per cent renewable instead of fossil fuels?”

He added: “So the research, the new technology, is to find materials that are more abundant, less problematic, more safe and cheaper systems – new technologies that are simply cheaper.”

Is zinc the answer?

A few alternatives are being looked at which use materials that don't break the bank.

These include batteries using what are sometimes called post-lithium-ion technologies, including lithium-sulphur and lithium-air, and post-lithium technologies, which include zinc-ion, potassium-ion, sodium-ion and magnesium.

“They’re following similar principles in the way the system works, the battery works, however using different materials that are cheaper,” Prof La Mantia said.

“Zinc is nowadays getting a lot of attention; magnesium a little bit less. Zinc is really more abundant than lithium – four to five times more, but less than sodium. From a safety point of view, the industry is interested in zinc products, they’re cheap to assemble and to produce.”

What does the future have in store?

Renewables will require serious progress around medium-term and long-term energy storage.

The global demand will be “huge”, according to Prof Yulong Ding, director of the Birmingham Centre for Energy Storage at the University of Birmingham in the UK.

He said that in the UK alone – which has less than one per cent of the world’s population – the demand for energy storage by 2050 will be as great as the current total global capacity.

“Different countries have different [demands],” he said. “For example, the UAE is very hot, so their need for heating is minimal but their need for cooling is high. But broadly, the needs for storage will be similar, namely short-term, medium-term and long-term storage.”

There are several technologies that could be used for medium-term storage, ranging from a few hours up to several weeks and even months.

Some of these involve what are called phase transitions, including systems that use energy to compress, cool and liquefy air. This liquefied air releases the energy stored within it when required.

Mechanical forms include compressed storage, which uses energy to compress and store the air, often underground, before it is released when needed to generate energy.

Hydrogen, Prof Ding said, can be used for long-term storage. “This could store energy for years,” he said.

With investments expected to be up to trillions of dollars by 2040, when some analysis suggests energy systems should have decarbonised in order to hit climate goals, energy storage is set to be big business – and an essential one.

Sharrie Williams
The American singer is hugely respected in blues circles due to her passionate vocals and songwriting. Born and raised in Michigan, Williams began recording and touring as a teenage gospel singer. Her career took off with the blues band The Wiseguys. Such was the acclaim of their live shows that they toured throughout Europe and in Africa. As a solo artist, Williams has also collaborated with the likes of the late Dizzy Gillespie, Van Morrison and Mavis Staples.
Lin Rountree
An accomplished smooth jazz artist who blends his chilled approach with R‘n’B. Trained at the Duke Ellington School of the Arts in Washington, DC, Rountree formed his own band in 2004. He has also recorded with the likes of Kem, Dwele and Conya Doss. He comes to Dubai on the back of his new single Pass The Groove, from his forthcoming 2018 album Stronger Still, which may follow his five previous solo albums in cracking the top 10 of the US jazz charts.
Anita Williams
Dubai-based singer Anita Williams will open the night with a set of covers and swing, jazz and blues standards that made her an in-demand singer across the emirate. The Irish singer has been performing in Dubai since 2008 at venues such as MusicHall and Voda Bar. Her Jazz Garden appearance is career highlight as she will use the event to perform the original song Big Blue Eyes, the single from her debut solo album, due for release soon.

TERMINAL HIGH ALTITUDE AREA DEFENCE (THAAD)

What is THAAD?

It is considered to be the US's most superior missile defence system.

Production:

It was created in 2008.

Speed:

THAAD missiles can travel at over Mach 8, so fast that it is hypersonic.

Abilities:

THAAD is designed to take out  ballistic missiles as they are on their downward trajectory towards their target, otherwise known as the "terminal phase".

Purpose:

To protect high-value strategic sites, such as airfields or population centres.

Range:

THAAD can target projectiles inside and outside the Earth's atmosphere, at an altitude of 150 kilometres above the Earth's surface.

Creators:

Lockheed Martin was originally granted the contract to develop the system in 1992. Defence company Raytheon sub-contracts to develop other major parts of the system, such as ground-based radar.

UAE and THAAD:

In 2011, the UAE became the first country outside of the US to buy two THAAD missile defence systems. It then stationed them in 2016, becoming the first Gulf country to do so.

Key findings of Jenkins report
  • Founder of the Muslim Brotherhood, Hassan al Banna, "accepted the political utility of violence"
  • Views of key Muslim Brotherhood ideologue, Sayyid Qutb, have “consistently been understood” as permitting “the use of extreme violence in the pursuit of the perfect Islamic society” and “never been institutionally disowned” by the movement.
  • Muslim Brotherhood at all levels has repeatedly defended Hamas attacks against Israel, including the use of suicide bombers and the killing of civilians.
  • Laying out the report in the House of Commons, David Cameron told MPs: "The main findings of the review support the conclusion that membership of, association with, or influence by the Muslim Brotherhood should be considered as a possible indicator of extremism."

Pharaoh's curse

British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.
