The electrical storage movement and the global demand for graphite.

Why is Tesla targeting non-mobile storage systems? As an order-of-magnitude estimate, with full integration of worldwide renewable energy sources and maintaining a constant flow through the grid, up 2,8000 GW of electrical storage capacity (production and consumer) may be required worldwide.

There are currently three alternatives for the storage of electricity; lithium ion and vanadium reduction batteries, and fuel cells. All three use about four tonnes of graphite per MWhr. Assuming a slight grown in demand by the time the system is fully installed an initial total of 12 million tonnes of graphite plus an additional 1.2 million tonnes on a yearly basis (20 year lifespan and 5% annual increase in grid capacity) could be required.

To answer the Tesla question you have to know the current state of the electrical grid and alternatives to the increasing outdated, and overworked system. The present electrical grid infrastructure is decades old and is approaching 100% capacity during peak load hours; particularly on hot summer days. In a simplified form the grid consists of three components: generators, transmission and consumers.

However, there is often significant excess capacity at non-peak hours. Rather than expanding the current grid and replacing aging infrastructure, the availability of large scale electricity storage systems gives another alternative; that is a distribution system wherein significant power is stored at a consumer level and the even integration of renewables into the system. In the past physical means of storage have been advocated including pumping water into hydroelectric reservoirs and compressing air in underground caverns. None of these systems have proved to be viable. Thus the stationary battery or its alternatives.

Installed storage capacity would create a system that is more resilient to power failure allowing both consumption and production to continue when the grid is not available. With the exception extraordinarily long events, such as major storms, power disruptions would be a thing of the past. The storage system would also allow built in surge protection and very close regulation of the quality of the electricity both into and out of the grid. Such a system would also allow many parts of the grid to convert to high voltage direct current allowing existing transmission wires to carry up to 40% more power.

Generators consist of slow responding, but inexpensive base-load capacity, some more responsive generators for “shoulder periods” and quick acting peak generators. The base-load generators are always on-line and produce the even supply dictated by the demand minimum. Electricity on the grid must be balanced. Thus, as demand increases the faster responding generators are brought online or run at a higher capacity. Some generator power is not used, but is dissipated and can be brought on-line immediately in the case of surges. Without storage, what goes into the grid must come out. Renewable energy sources such as wind, solar, and tidal energy cannot be controlled thus can only make up a small percentage of the grid or instabilities result. This means that there are limits to the quantity of renewables that can be safely integrated.

Consider the case of solar power. Electricity is only generated during the day, peaking at about noon. The peak occurs during “shoulder”, or mid load thus would allow some of the moderately responsive generators to idle; but, solar cannot replace them as the power is required during evening hours. Also, the amount of generated power cannot exceed what those generators would normally provide as base-load generators cannot be idled in the same manner. Thus solar usage under the current system is limited. However, by adding storage to the system the solar generator could supply any capacity, to its maximum, upon demand. The amount generated depends on the weather, the latitude and the hours of sunlight which means that a storage safety factor will have to be included.

Solar is predictable, with minor variations. Tidal power is entirely predictable thus the easiest to compensate. Wind, on the other hand, is much more variable unless the turbine is located in a very favorable zone. Due to calm days and high velocity wind during storms there can be a considerable variation as captured by the wind generation in Germany during one month in 2009 as shown in Figure 2. A daily storage would not suffice for wind, rather, wind patterns over time would need to be analyzed to determine a monthly or even longer compensation storage system.



Figure 1: German wind generated power from January 2009. Red shows power output from storage systems that along with the power stored (green) would result in a constant power output.

As there are periods wherein there is no power generated the system must be capable of storing all power from the base-load output to the peaks and outputting all the power for that load from the batteries. The amount of electricity stored would be the maximum anticipated power as represented by the area of the largest red section (time and MW for MWhrs).

What is the total power that must be stored in order to maximize grid performance and totally integrate renewables into the system? As a very rough approximation, the total power generated in the world is on the order of terawatts, or thousands of gigawatts. Assuming a value of 4,000 GW and a further assumption that 30% of the power would have to be stored to create an even flow, there must be 1,200 GW storage ability worldwide.

The scenarios shown illustrate the even grid flow of electricity that can used to maximize the carry capacity of the grid. However, to allow this state of operation the consumer side also has to be buffered with electrical storage. Residential, commercial and industrial users of electricity do not have even demand during the day. Illustrations of these demand are shown in Figure 2 through Figure 4.

Figure 2: Typical residential daily electrical consumption over a 24 hour period. Green shows local battery storing power and red indicates battery output of power in order to create an even consumption of power with time.



Figure 3: Typical commercial daily electrical consumption over a 24 hour period. Green shows local battery storing power and red indicates battery output of power in order to create an even consumption of power with time.



Figure 4: Typical small industrial daily electrical consumption over a 24 hour period. Green shows local battery storing power and red indicates battery output of power in order to create an even consumption of power with time.

In all three electrical consumer scenarios the battery storage system required to create an equal demand with time is the area of either the red or green zones (both are equal). As both commercial and small scale industrial operate only during daylight hours they would require a larger storage system, compared to their total consumption then residence that always has a load. If it is assumed that this is half of the power, it means that, worldwide, consumer storage will be fairly similar to renewable generator storage. As an added benefit such a storage system would mean that generate or wider distribution grid failures could be compensated for at the local level for periods of up to half a day.

How much electricity would be stored at the consumption end of the grid? As an order-of-magnitude, this would be about 50% for both commercial and industrial and about 30% for residential resulting in a very approximate total of about 40% or 1,600 GW worldwide.

Nissan In Europe: Growing Despite Headwinds - Europe is slated to be the fastest growing EV market in the world. The Leaf is the top-selling electric vehicle in Europe.

Nissan has outperformed the European auto market this year, becoming the top selling Asian OEM in the continent.

Nissan, however, will face challenges in Russia due to the weakness of the ruble, which played a key role in expanding Nissan's operating loss in Europe last year.

Nissan is doing the right thing by tapping the fast-growing EV market in Europe though the LEAF by adding a larger battery to the car to enhance its range.

Europe is slated to be the fastest growing EV market in the world, and by giving an improved product to this market, Nissan should attract more customers.

Nissan's alliance with Renault will allow it to capture growth in the European car market more effectively on the back of the Common Module Family architecture, which will reduce costs.

Europe means a lot to Nissan. By volume, the continent buys about 19% of what Nissan sells worldwide. Fiscal year 2014-15 was the fifth consecutive year growth for Nissan in Europe, with total sales of 740,640 units, an increase of 11.5% from FY 2013-14. And this year too, it looks all set to break its previous sales records.

Strong momentum in EuropeFor instance, in the first half of the year, Nissan's sales in Europe increased 4.3% to 384,726 units. As it announced its record sales in the first six months of 2015, it became the top selling Asian brand in Europe, recording a market share of 4.2%.

Nissan's emergence as the bestselling Asian brand comes on the back of outstanding performance in a number of high volume markets, including the U.K. (+34%), Spain (+18%), and Germany (+11%), where numbers were up versus its main Asian competitor Toyota. In Italy, its passenger car sales grew by more than 23% for the first half of the year.

In fact, Nissan's registration growth in Europe in June outpaced the overall industry's growth rate in the continent. However, not everything is rosy for Nissan in the continent as we will shortly see.

The headwindsEarlier this year, Nissan announced operating income of 589.6 billion yen for fiscal year 2014, a 5.2% margin on net revenue of 11.38 trillion yen, led by demand in North America and Western Europe. Adding to the gains was the favorable yen-dollar exchange rate over the period.

But, the company had to witness an operating loss of 25.8 billion yen in FY 2014 in Europe as compared to 23.6 billion yen in the previous year. The higher loss was attributed to the Russian market, where the no-frills Datsun models boosted Nissan's unit sales, but the Ruble's almost 50% plunge in 2014 forced the company from taking orders of some vehicles at the end of last year to keep its profitability intact.

A look at the positives and negatives in the European car marketEurope's car market was up 14.6% in June despite the debt crisis in Greece. This was the biggest monthly increase for the European auto industry since December 2009. This growth is attributed to the weakening euro, new models, and steady economic growth in the continent. Europe's five biggest car markets posted double-digit growth last month after a disappointing May.

Germany was up 12.9%, the U.K. grew 12.9%, France rose 15%, Italy improved 14.4%, and Spain reported an increase of 23.5% in vehicle sales. Moreover, in the first half of this year, new passenger car registrations increased 8.2%, surpassing 7 million units. In comparison, Nissan's registrations have increased 21% so far this year, outpacing the overall industry.

However, such a steep rise in June registrations has been the subject of scrutiny by many analysts who have declared it an outlier. They have warned that self-registrations - a practice whereby dealers register vehicles to themselves - and heavy discounting "continue to distort the true level of demand in many countries." However, ACEA, the European manufacturer's association, has raised its forecast for full-year auto growth from 2% to 5%.

In fact, the European car market is growing at a faster pace than China and the U.S. this year, driven by wage increases and employment gains. However, Nissan might continue facing weakness in the Russian market, as the ruble has started weakening once again after a period of growth earlier in the year. The recent weakness is attributed to Iran's deal with the six other countries regarding oil exports, while economic sanctions against Russia are another problem that Nissan has to contend with.

What will drive Nissan in EuropeNissan, however, has chalked out a smart strategy to tap growth in the European market. The company has built a strong manufacturing presence in Europe, with factories in Sunderland, Spain, and Russia.

In order to tap the European market more effectively, Nissan is in alliance with French automaker Renault since 1999. The partnership is proving to be fruitful every year. In the year 2014-15, the Renault-Nissan Alliance posted record synergies of €3.80 billion, up from €2.87 billion in the previous year. Synergies are generated from cost reductions, cost avoidance, and revenue increases.

The Alliance has built a unique system, known as the Common Module Family (CMF) of modular vehicle architectures that is driving synergies between the two stakeholders. As a result of this architecture, both companies can share parts and design language, which helps them in saving costs. However, a key growth driver for Nissan in Europe will be the LEAF electric car.

Leaf sales in Europe were up 21% to 7,201 units through May. In fact, the Leaf is the top-selling electric vehicle in Europe. This is good news for Nissan investors, since Europe is the fastest growing EV market across the globe. This is good news for Toyota, as the market for hybrid vehicles in Europe is anticipated to grow at a rapid pace going forward and outperform the global growth rate.

It is anticipated that EV sales in Europe were 75,000 units in 2014. Looking ahead, sales of EVs in Europe are expected to increase to 775,000 units by 2020, more than 10 times as compared to last year. The following chart indicates that EV sales in Europe will remain robust growing forward:



Now, in order to tap this fast-growing EV market, Nissan is making improvements to the LEAF by increasing its range. As reported by Day Herald:

"According to Automotive News, a long-range 2016 Nissan Leaf could be launching soon. However, keep in mind that this longer-model isn't going to be a 2017 or 2018th edition.

In fact, it will be a new update to the long-running Nissan Leaf, introduced in 2010. Automotive News further details that the new battery will have a 30 kWh capacity which is an improvement over 2015's 24kWh."

Thus, by improving the LEAF's battery size by 25%, Nissan will be able to attract more customers by reducing range anxiety. This will help the company increase sales of this vehicle going forward, and allow it to tap a greater proportion of the European EV market.

ConclusionNissan has been able to outperform the European auto market by leaps and bounds in 2015. Looking ahead, this trend will continue, especially due to its Nissan LEAF electric vehicle. Moreover, the company's alliance with Renault will act as a driver for its bottom line performance. Thus, driven by its strong performance in Europe, Nissan can continue getting better in the long run as the continent contributes close to 20% of its overall volumes, as mentioned earlier.
