Battery Storage

The energy storage market is expanding quite rapidly, driven largely by the increasing
availability of affordable energy from renewable sources.

Energy storage helps during emergencies like power outages from storms, equipment failure, accidents or even terrorist attacks. But the game-changing nature of energy storage is its ability to balance power supply and demand instantaneously – within milliseconds which makes power networks more resilient, efficient, and cleaner than ever before.

Energy storage is needed on a grid-scale for three main reasons. The first is to “balance load” – to shift energy generation into the future, often by several hours – so that more generation capacity is used efficiently. The second reason is to “bridge” power – in other words, to ensure there is no break in service during the second to minutes required to switch from one generation source to another. Finally, power quality management - the control of voltage and frequency to avoid damaging sensitive equipment – is an increasing concern that storage can alleviate whenever needed, for a few seconds or less, many times each day.


Another benefit is that energy storage systems are ‘fuel neutral’, regardless of the source. Energy storage captures excess electricity at high efficiencies for optimal use during outages, peak hours, or whenever grid management is a challenge.


Today’s electricity grid is increasingly vulnerable to threats from nature, terrorists, and accidents. Millions of families and businesses are victimised by outages each year. Power outages cost us $130 billion globally annually, hitting the job-creating commercial and industrial sectors hardest. Energy Storage can significantly reduce the vulnerability of the grid.


Energy Storage supports the integration of renewable energy generation. Energy storage can also help cut emissions by improving green energy efficiency and reducing the need for fossil fuel generation. Peaking generation is one of the most costly and wasteful aspects of the grid, so making the existing generation go further and avoiding capital and resource-intensive new facilities would make a significant contribution to our environmental priorities.


Energy Storage is going to be a vital part of the UK’s energy generation and distribution system, helping smooth out intermittency of renewable generation systems and ensuring consistent supply on the grid. The electricity sector is currently undergoing its biggest transformation for over half a century. The necessity to bring in renewable energy generation sources, coupled with the associated adjustments required to the distribution network (allowing these sources to contribute to the national grid) means energy storage is integral to these major changes.


The world will witness an international mega shift towards energy storage – batteries in particular – within the next 10 years according to ARENA (Australian Renewable Energy Agency). Further, according to Bloomberg New Energy Finance, energy annual investment in storage systems will increase six-fold to £6.7 billion in 2024, and to £197 billion by 2040.


Energy Storage is not new; it has been around for a very long time, in fact over 200 years, ever since Alessandro Volta invented the very first battery. The vast applications of Battery storage have not been lost either, from electric cars to battery storage for the national grid; battery storage has long been touted as the next big thing that never materialised. The reasons for this are simple – technology and cost. Whilst the theory of all of these applications was possible and proven, it was simply usurped by cheaper and more effective technology. That has now changed and not only can battery storage compete, it is now becoming much better.


The best example of this would be Tesla Electric Vehicle’s; just 15 years ago Electric Vehicles were effectively very expensive, glorified golf buggies. Today Tesla is producing electric cars that are cost competitive, can travel over 300 miles on a single charge, and in the case of the Tesla Model S P100D can do 0 – 60 mph in 2.5 seconds, that’s the same as the $1.7 million Bugatti Veyron. Battery storage on a home level and national level is also experiencing the same advancements.


Energy storage now looks as though it has reached the tipping point and will be one of the fastest growing sectors within renewable energy, which is the fastest growing industry in the world.



Economic landscape of the renewables sector

“Push Me, Pull You!” Subsidies, Taxes, and Storage
It is difficult to understand the logic behind Britain’s policy toward renewable energy. To meet its plans for a low-carbon economy it has been estimated that Britain requires £1.4 trillion of investment to fund its transition to net zero by 2050 , but in the recent budget, the government has announced plans to tax excess profits at a rate of 45% of some renewable energy companies who have been the recipients of past public support to induce investment to raise generating capacity. According to the statement by Jeremy Hunt justifying the decision: “The structure of our energy markets creates windfall profits for low-carbon electricity generation. “
Reform wholesale electricity pricing before the next crisis
In this paper we argue that the United Kingdom is evolving from a hierarchical vertical linear electricity system to a decentralised complex system. However, as the electricity system’s structural complexity increased, there has been no attempt to modify a broken regulatory system where the politically sensitive price-capped retail price for energy is based on distorted national wholesale prices which no longer reflect actual local market supply or demand conditions for electricity nor provide the correct market signals necessary to attract investment to meet net-zero targets.
Sky News on the importance of batteries
Sky News reports that batteries will become increasingly important to the energy grid as the UK transitions to green energy. Power storage will also become more critical as our electric demand increases.
Stagflation and Net Zero
It is popular to blame the invasion of Ukraine on rising energy inflation, particularly oil and gas prices, but there are sound structural reasons why the cost of generating electricity from these sources will continue to rise globally in the coming years. Russia’s militarism is a humanitarian disaster and will place inflationary pressures on food prices, but despite these problems, the UK government is hiding behind the short-term consequences and is not honestly communicating the real economic cost of moving to net-zero by 2050 and meeting the planned carbon reductions by 2030. In addition, the policy measures such as raising interest rates that are being promoted by many economists to meet the problem of stagflation (rising prices and falling output) will only exacerbate the pathology, while making the transition to a low-carbon future more painful.

The CCC says all that’s required is for the government to just go for it.
Today’s progress report – meant to assess the government’s annual progress against climate targets – is unlike any other that precedes it.
Demand for storage surging
The expected rate of return on battery storage facilities is rising sharply as demand is far outpacing supply. In the short-term the imbalances stemming from the fall off in the demand for electricity stemming from the COVID-19 induced downturn in economic activity is pushing up the utilisation of off grid batteries.
