Renewable Energy merits and drawbacks in application for Masses

By Khubaib Khan – Director ECO ESS Ltd. UK

Dark clouds and faded greenery are asserting openly and challenging to the humankind if you don’t awaken then get ready for more strikes – bad to worse breathing atmosphere has become the anti-body free of cost silent killer for many and despite of a buzz we don’t wake up.

Shielding of the atmosphere & our surroundings is the responsibility of the individuals but not only for the authorities. Let’s contribute by changing this unpredictable environment into a friendly nature. Handful Cos. in the UK, EU and USA have been contributing towards clean energy and swapping fossil fuels energy by renewable energy and sustainable energy that’s ultimately directing towards Zero CO2 emission. We all must be ambitious in this expedition and say let’s promote renewable energy and store valuable energy for better tomorrow, for the world & for the generation to come. In Unies, colleges and schools, we must add a line in title of their text books and notes – “Save the earth and save the nature by going green”.

With my immense research work, I identified that strong loophole persists in implementation and awareness of renewable energy on the mass level, despite of the loud slogans, activates, COP26 agenda, meetings, exhibition, seminars incentive schemes, big talks in developed countries specially in the EU, UK and in the USA. Ironically, Asia & Africa are unaddressed except China where the pollution and CO2 are its max. level of this era.

Green West does not nuisance for the polluted Asian & African atmosphere. Policies have been drafted, PM of few countries and their legislatives are in scene but reality is, their own progress is slow indeed and least public awareness being generated. Mega projects for renewable energies are in hands of few. The supplier i.e. manufacturer and buyer’s bond is stiff enough that the small Pvt. sector cannot courage to jump into this sector. Funds are for those Cos. who are the giant and can build-up mega project but what about small enterprises and individuals – how to encourage them? Is a valid question.

The major types of renewable energy sources are:

In this instance, I started asking my peers and industries fellows including capitalist and Tycoons of Gigawatt-projects owners what is the solution of slow coach towards decarbonisation? Why the hydraulic and Biomass / Waste energy cannot be the replacement?

Answer is unanimous, ‘most of the nation cannot afford hydraulic energy since don’t have much infrastructure and water flows and waste energy is another CO2 source somehow’. Compressed natural Gas is disputed – either its free from CO2, better than fuel or its lesser harmful than others fossil fuels. Thermal energy is also in doubt too either it is the best source for energy production or harmful to humankind? Blue energy is practically in fantasies and theories and in hand of few generalists and with money makers & markets. No one has seen blue energy so far, their actual form and how it can be generated. In fact, blue energy is just a theory and not coming to the practical review anywhere except in few texts. 

Therefore, Long duration Energy Storage Solution (ESS) is needed to substantiate the Renewable Energy for masses either extracted by Wind or by Solar energy. One of the best option and solution is Lithium Titanate Battery for individual houses from 3KW/h to 10KW/h. Though, LTO is relatively costly but pays off its cost in few years since life cycle is 30+ years. LTO is the safest, fastest and highly efficient ESS in both charging and discharging states. But LFP realistically is the economical solution as of today. It is the best option for individual houses, small industries, farm houses, machineries, backups etc even for EV and Electric cars can rely on this Li Ion form. This is another topic as a whole that prices are being rocketed and one could say this is due to the demand vs. supply. But questions are raised on Li Ion batteries as well – Millions of boxes where to be dumped after their usage and expiry or it’s another add on to the pollution and destroying the nature. Answer was received – these are minerals or synthetically produced molecules and can be dumped to the nature earth from where they originated – answer is elementary and needed further debate since Govt of UK have published 100s of pages on Li Lion batteries where and how to dump safely after their expiry – these good deeds with good intention by UK Gov. raised 10s of questions spontaneously.   

In my strong opinion, Westerns Govts must ponder on the LFP factor till the time energy distribution should emerge from the alternative mega solar plants along with wind parks. Automobility has to run on the aid of these Li Ion batteries since they don’t have other option so far in this era unless something originated from the surface to replace these powerful and long-lasting Li Ion batteries. 

I had extracted few excellent articles and quotes which are self-explanatory and would clarify the picture which is gloomy but foggy as far as commercial part is concerned and needed a lot of attention from top world-wide think tanks – if not today then get ready to face rebellious nature tomorrow in form of more shocks, jolts, floods, tsunami, drought, hunger, poverty and faded nature. (God forbid)  

Energy Storage Latest

“Renewable energy has come a long way in the past decade, and it’s still trending upward going into 2022. These days, “carbon-efficient, all-natural” energy is the norm, incorporated into everyday life with an irreversible effect on society.

The International Renewable Energy Agency (IRENA) names renewable energy the backbone of global development and climate strategy.

In other words, our world has become dependent on renewable energy. Production has increased exponentially and the world has doubled its capacity over the past decade. But the main contributor to renewable energy’s success is the way in which we store that energy. It has an enormous shelf life, which increases demand.

In fact, this growth will increase by 13 times in grid-scale storage by 2024.

This is a monetary equivalent of $71 billion.

Global Market Insights sees energy storage systems reaching $500 billion by 2025.

Energy storage including lithium batteries, solar panels, and microinverter-based storage systems allows this renewable energy boom to continue.

Not to mention energy storage also allows for a massive opportunity to enter the market in a very solid and secure way.

And I happen to have three red-hot energy storage stocks that can get you started in profiting from the renewable energy industry.”

Energy Stoarge is the Future

“The energy storage industry should play a proactive role in supporting market development in Southeast Asia, a panel discussion at the Solar and Storage Finance Asia event heard this week, from Aquila Capital regional CEO Alexander Lenz. We speak exclusively with Yaron Ben Nun, CTO and founder of Nostromo, a start-up aiming to commercialise a new ice-based energy storage for cooling buildings and Yaron is adamant that it can turn electricity demand for commercial buildings into a powerful tool of the energy transition. US independent power producer Talen Energy has hired developer Key Capture Energy to work on a battery project at one of its coal power plant sites in Maryland, as Talen pursues its new ESG-driven path. Koch Industries, another name more commonly associated with fossil fuels, has invested in zinc-based energy storage company Eos, through its Koch Strategic Platforms investment vehicle. The UK’s Flexion Energy has gained a US$200m+ investment commitment from an infrastructure investment group as it targets development of a 1GW battery storage portfolio and in South Australia, developers Maoneng and SAPGen are seeking permission to construct 465MW of large-scale battery storage, solar-plus-storage projects behind-the-meter and in front-of-the-meter make progress in Hawaii. Finally, we round up some news about investors acquiring three US solar and storage developers, which could be a sign of things to come.” By Andy Colthorpe

AN ENERGY SYSTEM ON THE BRINK OF TRANSFORMATION

“The global transition to renewable energy has been accelerating worldwide, driven by the urgent imperative to address the climate emergency and increasingly favourable economics.

This has been supercharged by the impact of the Covid-19 pandemic, creating unique conditions to accelerate the transition, with the IEA recognising that renewable energy, such as wind and solar, showed ‘a degree of immunity to the crisis’.1 The temporary acceleration of the share of renewable energy driven by Covid-19 has fixed the eyes of the world’s energy leaders on the opportunity to realise the potential of renewables to reduce emissions, permanently. The UK is one such test-case.

The UK Prime Minister has increased the Government’s offshore wind target from 30 GW to 40 GW by 2030 and pledged that offshore wind will power every home in the country in that time. This will form a keystone in the country’s path to a net zero energy system.

The UK Government will soon release its energy white paper, detailing its strategy for the coming decade and beyond. This is an opportunity to set an ambitious target for renewable energy to become the primary source of power by 2030. In 2019, the UK energy system reached 37% renewable energy.

By 2030, modelling undertaken by Wärtsilä shows that the country could easily achieve a permanent 62% renewable generation, even with the energy system as it is today. The country should go further, setting a target to achieve 80% renewable energy by the end of the decade. That may sound ambitious, but it is realistic. During the initial Covid-19 lockdown, when energy demand fell by up to 10%, the energy system as it is today coped with up to 60% renewables for short periods. Energy systems in other European countries, such as Germany and Spain, achieved over 70% renewable energy. If current systems can manage major spikes of renewable energy today, then – as this report shows – with investment in technologies that add system flexibility, we can be confident to set ambitious targets for permanently higher levels of renewables in the near future.”

The question of bankability: From tech to revenue model

Laurent Segalen states that “from a financial point of view, li-ion batteries are now a fully bankable technology. World-class providers like Fluence and Tesla are delivering new products with up to 20,000 cycles and above 90% round-trip efficiencies. And lithium ferro phosphate (LFP), with its lower cost and reduced fire risk, seems now the chemistry of choice for stationary storage.

Now that the technology aspect has been sorted, how can the revenue model of stationary storage become bankable? Contrary to wind and solar, batteries don’t typically benefit from long-term secured revenues, such as power purchase agreements (PPAs).

Instead, investors in storage need to deal with several types of revenues (arbitrage, grid services, reserve) which are difficult to model. Even more important, capturing those new revenues relies on implementing ever-improving software that maximise the monetisation of the numerous market opportunities but can be often seen as “black boxes” by investors.

The software race is on. Against Tesla’s Autobidder, you see Fluence acquiring AMS to provide an integrated hardware + software solution. That new software is incomparably more suited to optimise battery assets than human traders. For instance, in Australia, the new market design has created five-minute bidding windows: the best human trader will post 15-20 trades a day, whereas the software will be able to bid 288 times (12 bids per hour x 24h).” Published in Financier, renewable energy transactions.

Summary:  I could sum up in below sentences.

The renewable energy problem:

There are some days when;

  • the sun doesn’t always shine, and
  • the wind doesn’t always blow.
  • And then there are days when these happen for extensive periods.
  • This causes intermittency & variability of your renewable energy generation.

The natural environment has a massive impact on the balancing capability of renewables. Which often results in decreased commercial capability of your renewable assets.

How can we increase the capability of renewable assets?

Grid scale storage solutions

By applying unique storage expertise into renewable energy generation projects, one can transform the value of your assets, ‘get a detailed roadmap for your route to the market and achieve your goals.’

Why Do You Need a Solar Battery Storage System?

Pairing solar batteries with solar arrays is a relatively new practice, but an effective one. You can benefit from solar battery storage in 4 key ways:

  1. Store energy for later use
  2. Significantly lower your energy costs
  3. Earn money by selling stored energy to the grid
  4. Become independent from the grid 

Firstly, a solar battery stores the energy generated during sunlight hours and makes it readily available for use during non-production hours, such as at night or on cloudy days, essentially enabling your home to run on 100% renewable solar energy around the clock, as long as electricity demand does not exceed the supply that the battery can provide.

In addition, solar battery backup power can lower your energy costs significantly. By charging the solar battery during off-peak hours and discharging it during peak hours, you can avoid paying a lot for electricity from your utility company. The savings from this can serve towards reducing your battery system costs.

What’s more, you can earn money by selling the energy stored in your solar battery back to the electrical grid when electricity prices are at their highest—if your utility allows net metering.

Finally, by adding a solar panel battery to your solar system, you can choose to be independent from the national grid at any time, thereby ensuring energy security for your household. Naturally, the how many solar panels you need to install for this will vary depending on your energy demands and budget.

AC vs. DC Coupling Energy Storage Systems

Lucas Miller March 4, 2021

At Mayfield Renewables, we routinely design and consult on complex solar-plus-storage projects. In this article, we outline the relative advantages and disadvantages of two common solar-plus-storage system architectures: AC coupled and DC coupled energy storage systems (ESS).

Before jumping into each solar-plus-storage system, let’s first define what exactly a typical grid-tied interactive PV system and an “energy storage system” are.

Looking at the diagram below, a simplified interactive PV system is composed of a DC power source (PV modules), a power converter to convert from DC to AC (interactive inverter), and AC loads (main service panel). 

When the sun is shining, the PV modules produce DC power. That power is fed through the interactive inverter which then feeds the main service panel. The interactive inverter “interacts” with the grid to send excess power to the utility and also will shut down during a power outage. This prevents the PV modules from producing power which could energize downed power lines.

Interactive PV System String Inverter.MR logo.png

Now that we have a simple grid-tied system, let’s build onto it by adding energy storage. The 2017 Article 706.2 of the National Electrical Code (NEC) defines an energy storage system as: “One or more components assembled together capable of storing energy for use at a future time. ESS(s) can include but is not limited to batteries, capacitors, and kinetic energy devices (e.g., flywheels and compressed air). These systems can have ac or dc output for utilization and can include inverters and converters to change stored energy into electrical energy.”

For the purposes of our analysis, we loosely define ESS as a component(s) of our circuit designed to store energy for later use (e.g., a lead-acid or lithium-ion battery bank).

AC Coupled Systems

As mentioned above, PV modules will produce DC power. That power must be converted to AC to be used in most commercial and residential applications (e.g., typical electrical loads for buildings and homes). In contrast, battery cells must be charged with DC and will output DC power. The AC-DC distinction has major system design implications.

In an AC coupled system, power from the PV modules is converted to AC prior to connecting to the ESS. In other words, the output from the PV modules is fed through an interactive inverter before it reaches the ESS. This means that the power must be converted to DC before charging the ESS, and any power output from the ESS must be converted once again to AC. To achieve this, an additional multimode inverter is required.

AC Coupled Multimode System.MR logo.png

Moving from left to right in the diagram above: The PV array produces DC power, which is immediately converted to AC by the interactive inverter. That power feeds a backup loads panel containing select loads formerly located in the main service panel. The backup panel is also connected to the ESS, with a multimode inverter acting as a middleman to convert AC to DC when the ESS is charging, and DC to AC when discharging.

In this setup, it’s possible for the PV array, backup loads panel, and ESS to operate independently from the grid. During a power outage, the multimode inverter—using power from the ESS—will mimic signals from the grid, allowing the interactive inverter to stay online and the PV array to continue producing power to feed the backup loads panel and charge the ESS with any excess power.

DC Coupled Systems

DC coupled systems rely only on a single multimode inverter that is fed by both the PV array and ESS. With this system architecture, DC output power from the PV modules can directly charge the ESS. No DC-to-AC conversion is required between the PV array and ESS. 

The backup loads panel and main service panel—both of which require AC power—are placed downstream from the multimode inverter. In the case of a power outage, the microgrid interconnect device (which is commonly integrated into the multimode inverter) will cut off the multimode inverter’s output to the main service panel but the inverter will continue to supply AC power to the backup loads panel.

DC Coupled Multimode System.MR logo.png

Moving from left to right in the diagram above: The PV array outputs DC power to the ESS and the multimode inverter. The multimode inverter will convert the DC power to AC and any power in excess of the loads in the backup and main service panels (or that is used to charge the ESS) is exported to the grid.

Advantages of AC Coupling

Retrofits

Adding an ESS to an existing grid-tied interactive PV system is not uncommon. Doing so can cause headaches for system designers, and the easiest solution is often AC coupling the new ESS. 

Compare the simple interactive PV system and the AC coupled system above. Note that in both cases, the PV side of the system is the same. AC coupling will add a backup loads panel and multimode inverter but, crucially, the existing PV system does not need to be redesigned. 

Higher Inverter Capacity

A DC coupled system relies on only a single multimode inverter and is thus limited by its capacity. AC coupled systems have two inverters (one interactive and one multimode), both of which feed the backup loads panel. So if an outage occurs while the sun is still shining, the backup loads panel can have the kW capacity of both inverters available.  

Redundancy

As with any electrical system, PV designers should consider potential points of failure. In an AC coupled system, if the battery-based multimode inverter is disabled, a simple bypass switch will keep the PV array and interactive inverter online (as long as the grid is up). This is not the case for DC coupled systems, which are reliant on a single multimode inverter at the heart of the system architecture. 

Efficiency

Interactive inverters tend to be more efficient than multimode inverters. If the sun is shining and the power being produced is consumed immediately (i.e., the power output from the PV array is directly feeding the loads rather than passing through the multimode inverter to charge the ESS) an AC coupled system architecture will be more efficient than its DC counterpart. 

Advantages of DC Coupling

Efficiency

While an AC coupled system is more efficient when the PV array is feeding loads directly, a DC coupled system is more efficient when power is routed through the ESS (e.g., when the ESS is charged directly and discharged at a later time) since there is only one conversion from DC to AC—a single inverter, rather than two, to pass through.

Full PV Array Power

In typical interactive and AC coupled systems, inverters are downsized under the assumption that the PV array will rarely, if ever, produce at its nominal rating. For example, consider a 5kW PV array that is tied to a 4kW interactive inverter. This hypothetical system is now limited to a nominal 4kW power output. 

For DC coupled systems, the power feeding the ESS is not limited by an interactive inverter. Returning to the hypothetical system above, but without the interactive inverter this time, a theoretical maximum of about 5kW could be used to charge the ESS and/or feed the multimode inverter without any power limiting. 

Direct Charging

Low-battery-voltage situations can arise within AC coupled systems. If too much energy is pulled out of the battery bank during an outage, that energy can cascade throughout the system, shutting down the multimode inverter, then the interactive inverter and the PV array. Since there is no way for the PV array to directly charge the batteries in this case, system owners may have to wait for grid power to return before the system can come back online.

Conversely, a DC coupled system can continuously send power (during daylight hours) directly from the PV array to the ESS. The unincumbered pathway between the PV array and battery bank allows the battery voltage to rise and thus the multimode inverter can turn back on and supply power to the backed-up loads without having to wait for the grid power to return.

What are the driving forces behind decarbonisation?

“COP26 aside, financiers are being driven to invest in decarbonisation by the brute reality of the climate crisis, by public pressure, and by shifting market forces.

Spooked by the risks of inaction, 45% of banks disclosing to CDP — the global environmental impact disclosure non-profit group — have aligned their portfolios with net zero. This empowers green technology companies. 

Despite the pandemic, 260GW of new renewable generation was deployed globally in 2020 – smashing former records by almost 50 per cent. The electric vehicle (EV) sector raised US$28 billion, 10 times more than in previous years.

And we are seeing increasing support for the key technology linking renewable generation with zero-carbon transport: battery storage. 

The forces behind the energy transition are expanding the market for new storage technologies. The global storage market is poised to increase by 23% by 2030. As the market grows, regulation will respond, making it easier for battery operators to meet the needs of energy systems. 

We are already seeing this in the UK. The Government is consulting on opening up the transmission network to competition, so that new technologies can resolve constraints at lower costs to consumers. The Pathfinders programme of the national electricity system operator National Grid ESO, is enabling operators to stack revenues, so that they can provide multiple flexibility services at once.

These changes make it more likely that we will hit the 18GW of storage capacity we need to run a zero-carbon system.”

Era of Energy Storage

“Volkswagen recently placed an order worth US$14 billion with lithium-ion battery manufacturer Northvolt, taking their existing partnership to new heights and while the obvious focus there is electric vehicle batteries, we’ve heard exclusively from Northvolt’s VP of communications Jesper Wigardt that the deal will also have a significant knock-on impact for the startup’s targeting of the stationary energy storage market. South Africa’s government identified an urgent need for capacity to prevent load shedding on its grid and renewables-plus-storage projects have been among the winners in a tender for 2GW of contracts. Consultants Clean Horizon and Harmattan helped us out with some insights there. In Germany, more than 300,000 residential energy storage systems have now been installed, and while energy storage at larger scales has been somewhat less successful over the past year or so, every segment is expected to grow this year, a new report commissioned by Germany energy storage association BVES has found. New York City’s 6GW of fossil fuel peaker plants could be retired quickly and cost-effectively between now and 2030 using a combination of renewable energy, energy efficiency, and of course, energy storage. There’s also a roundup of some of the latest news stories from the residential energy storage segment around the world, Canadian Solar has big ambitions in solar-plus-storage and standalone energy storage for 2021 and just a month after applying for approval for a large solar-plus-storage plant, two Wisconsin utilities have put forward a plan for another. All this and much more on the site. Thanks for reading and subscribing.”

Advantages of Renewable Energy

“Advantages of Solar Energy

1. Renewable Energy Source

Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source. It can be harnessed in all areas of the world and is available every day. We cannot run out of solar energy, unlike some of the other sources of energy.

Solar energy will be accessible as long as we have the sun, therefore sunlight will be available to us for at least 5 billion years when according to scientists the sun is going to die.

2. Reduces Electricity Bills

Since you will be meeting some of your energy needs with the electricity your solar system has generated, your energy bills will drop. How much you save on your bill will be dependent on the size of the solar system and your electricity or heat usage.

For example, if you are a business using commercial solar panels this switch can have huge benefits because the large system size can cover large chunks of your energy bills.

Moreover, not only will you be saving on the electricity bill, but there is also a possibility to receive payments for the surplus energy that you export back to the grid through the Smart Export Guarantee (SEG). If you generate more electricity than you use (considering that your solar panel system is connected to the grid). 

3. Diverse Applications

Solar energy can be used for diverse purposes. You can generate electricity (photovoltaics) or heat (solar thermal). Solar energy can be used to produce electricity in areas without access to the energy grid, to distil water in regions with limited clean water supplies and to power satellites in space.

Solar energy can also be integrated into the materials used for buildings. Not long ago Sharp introduced transparent solar energy windows.

4. Low Maintenance Costs

Solar energy systems generally don’t require a lot of maintenance. You only need to keep them relatively clean, so cleaning them a couple of times per year will do the job. If in doubt, you can always rely on specialised cleaning companies, which offer this service from around £25-£35.

Most reliable solar panel manufacturers offer 20-25 years warranty.

Also, as there are no moving parts, there is no wear and tear. The inverter is usually the only part that needs to be changed after 5-10 years because it is continuously working to convert solar energy into electricity and heat (solar PV vs. solar thermal). Apart from the inverter, the cables also need maintenance to ensure your solar power system runs at maximum efficiency.

So, after covering the initial cost of the solar system, you can expect very little spending on maintenance and repair work.

5. Technology Development

Technology in the solar power industry is constantly advancing and improvements will intensify in the future. Innovations in quantum physics and nanotechnology can potentially increase the effectiveness of solar panels and double, or even triple, the electrical input of the solar power systems.”

2020 was the UK’s Year of Battery Storage

ESS

“Solar Media Market Research, which is the in-house team of experts at Energy-Storage News’ publisher Solar Media, tracked 60 new planning applications for large-scale battery storage projects in the UK last year, representing some 1.2GW of capacity. Lauren Cook said that activity has increased year-on-year in this regard and business models are changing quickly. Legislation has also shifted to allow projects of over 50MW capacity to bypass the Nationally Significant Infrastructure Project planning status that larger projects previously had to attain.

“The battery storage pipeline in the UK has reached over 14.5GW with around 1.2GW operational. The pipeline is continuing to grow as we see increasing number of projects of 50MW and larger,” Lauren Cook told Energy-Storage.news in an interview.

“There is also increased interest in battery storage co-located with wind and solar and we are now seeing more planning applications being submitted for these projects.”

Energy-Storage.news asked Cook how much of an impact lifting those rules that limited projects to under 50MW would have. During the webinar, the analyst had said that of projects deployed and planned in the UK, the largest share by percentage had been projects with 49.9MW rated output: in other words, the largest that developers could make them while complying.”
