Tesla’s Megapack Powers its Small, But Growing Energy Storage Business

on July 24, 2020

Tesla’s energy storage business picked up steam in the second quarter and even played a minor role in the company’s fourth consecutive quarter of profitability, according to earnings reported Wednesday.

Commercial and residential energy storage sales as well as solar are still mere slices of Tesla’s overall business, which is largely dominated by automotive. However, second-quarter results show some promise for energy storage, particularly Megapack, the utility-scale energy storage product that launched in 2019 and is modeled after the giant battery system it deployed in South Australia.

While Tesla does provide separate deployment stats for solar and energy storage, it combines the two when reporting revenue, making it impossible to fully measure the success of Megapack. However, Tesla made a point in its earnings statement to flag Megapack as a winner in the second quarter, and noted that it turned a profit for the first time.

“There’s a lot of demand for the product and we’re growing the production rates as fast as we can,” Drew Baglino, senior vice president of powertrain and energy engineering, said during Wednesday’s earnings call.

For the past four years or so Tesla has been asking investors to view it as an energy company instead of just an automaker. Some analysts think that the real value in Tesla’s business will be when it actually achieves some level of parity between the two sides of the shop — a goal that Musk is also shooting for.

But energy storage and solar has remained in Tesla’s automotive shadow, despite assurances that these business products will eventually be equals. For now, energy storage remains a small, but growing, fraction of Tesla’s revenue.

Nanogrids: A New Opportunity for the Solar Industry & its Customers

on July 23, 2020

What exactly are nanogrids? Think of a microgrid, but:

  • Smaller, which means quicker and easier to deploy and more affordable
  • Localized, so customer centric and able to be tied to other nanogrids, microgrids and the utility macrogrid
  • Able to be aggregated, which can create a coordinated response to support other grids in times of emergencies

Both nanogrids and microgrids are forms of local energy—self-sufficient systems with power generation, controls and often energy storage—that serve customers within a discrete footprint. Although they can operate on their own, most North American microgrids and nanogrids are also connected to the central grid. They are able to island from the larger grid and operate independently during power outages. Electricity continues to flow to homes and buildings served by microgrids and nanogrids even as others around them are in the dark. This is a prime reason for their installation, one that is especially important given that the U.S. is experiencing more outages caused by storms, wildfires and other dangerous conditions that affect the safety of communities. Meanwhile, power outages to homes, a prime market for nanogrids, are no longer a mere inconvenience; they can carry significant costs now that more people are working from home. Indeed, COVID-19 created situations where high ranking corporate officials were operating from their houses, shifting the corporations’ de facto headquarters to residences that lack the kind of backup energy systems more likely to be found at their office complexes.

But it’s not only electric reliability that makes these systems attractive. Because they are tied to the electric grid, they may supply services to it and be paid for doing so. For example, a utility might pay to tap into a nanogrid’s battery at a time when demand is high on the electric grid and it needs more energy, such as a hot day when air conditioning use is high.

Nanogrid and microgrid owners also can save money if they use energy from their systems, instead of the grid, during times when grid power is expensive.

Another important benefit of nanogrids is their interconnectivity to a larger scale smart grid. An aggregated network of nanogrids can be very valuable to the grid. Currently, solar is generating power at times of the day when energy is at lowest demand. Besides simply turning off the solar panel production, through a practice called curtailment, the utilities do not have an effective way of managing all the separate points of intermittent connection. They don’t have a way to store the solar power effectively. In addition, at times when the utilities need the power most, current independent solar systems cannot necessarily supply it because they lack the intelligent technology to do so. This is partially due to the fact that the solar energy is not being produced at those critical times of the day. Nanogrids can help solve this problem.

Guidehouse: Utility-Scale Energy Storage Industry ‘Blossoming’ in Several US States

on July 22, 2020
Energy-Storage-News

The US utility-scale energy storage market is projected to maintain its position as the world’s largest and fastest-growing in the coming years, according to a new report from Guidehouse Insights.

Despite the rapid growth, the development of new utility-scale energy storage systems (ESSs) remains highly concentrated in a few states. The market research provider’s report shows California, New York, and Texas lead the top 10 US energy storage markets.

Alex Eller, senior research analyst with Guidehouse Insights, said utility-scale energy storage in the US “has quickly transformed from an expensive and poorly understood niche technology to a major source of new investment”.

“While several states have seen a blossoming storage industry, many others have little to no utility-scale energy storage currently operating,” he said.

“However, this reality is expected to change quickly as the falling costs of batteries and other technologies allow utility-scale energy storage projects to compete directly with conventional fossil fuel systems.”

The report, ‘Leading US States for Utility-Scale Energy Storage’, says the US utility-scale energy storage market is the most diverse in terms of the uses of energy storage and the number of competitors and technologies.

It notes that while the market is highly fragmented, additional states are quickly emerging as strong markets. However, the report warns of varying market structures, regulations and economic applications for projects in different states.

Value of Energy Storage Lies in Increased Renewables and Capacity Deferrals

on July 22, 2020
Renew-Economy

A new study has concluded that the economic value of energy storage increases as variable renewable energy generation increases its share of electricity supplied, however, the degree to which such variable renewable energy sources can be deployed hinges upon the future availability and cost of energy storage technologies.

The new study recently published in the journal Applied Energy was authored by researchers from the Massachusetts Institute of Technology (MIT) and Princeton University’s Andlinger Center for Energy and the Environment (ACEE), supported by General Electric (GE).

The research analysed battery storage technology in an effort to determine the key drivers impacting its economic value, how that value changes with increasing deployment over time, and the implications for energy storage’s long-term cost-effectiveness.

“Battery storage helps make better use of electricity system assets, including wind and solar farms, natural gas power plants, and transmission lines, and can defer or eliminate unnecessary investment in these capital-intensive assets,” said Dharik Mallapragada, research scientist at the MIT Energy Initiative (MITEI) and the paper’s lead author.

“Our paper demonstrates that this ‘capacity deferral,’ or substitution of batteries for generation or transmission capacity, is the primary source of storage value.”

There are other sources of value for energy storage identified by the report, including its ability to provide operating reserves to electricity system operators, avoiding fuel cost and wear & tear incurred by cycling on and off gas-fired power plants, as well as shifting energy from low price periods to high value periods.

However, the paper conclusively showed that these sources are of secondary importance compared to the value energy storage creates by helping to avoid capital-intensive capacity investments.

Enabling The Grid of The Future Requires More Than One Energy Storage Technology in The Toolkit

on July 21, 2020
Energy-Storage-News

Energy generation has never been a single technology market. Gas, coal, nuclear, hydro, solar and wind all make a significant contribution to our global generation capacity, and each play different roles based on their specific characteristics.

For instance, nuclear provides low-carbon baseload, whilst gas generally meets more flexible, peaking requirements with a higher carbon cost. Renewables, once a high-priced subsidy-only option, are now considered to be a key low-cost and low carbon part of our future generating mix.

The energy storage market is no different. I don’t believe there will be a ‘one size fits all’ technology solution, given the wide variety of technical requirements and market designs that allow grids to operate effectively.

Could one energy storage technology technically perform every conceivable requirement? Yes, quite possibly, but specialisation in the market will deliver far more economically optimal solutions.

Approaching the roles that storage can play with a single technology would be like leaving your toolkit at home and turning up to a DIY job with just a hammer – it’s capable of a great many things, but it really isn’t the best tool to paint the bedroom with.

Differentiation will emerge as energy storage grows in future grid scenarios
Instead of a one-size-fits all situation, I believe the future will see a segmentation in the energy storage market, driven by myriad factors including; technology type, age, warranty limitations, control systems, financing structures and operating strategies. The technical and economic factors driving this segmentation will necessitate different storage products for different applications; once deployed, a further segmentation for dispatch will evolve.

We can see this today, for example within gas there are a wide range of solutions, from reciprocating engines to combined-cycle gas turbines (CCGTs). Selection amongst these competing solutions is made at the time of deployment based on the specific purpose they are intended to serve. During their operational lifetime, each generator is dispatched to meet market requirements at lowest cost. The same will be true for energy storage. Within a storage fleet you’re going to have older installations (based on earlier technologies) coming to the end of their life, competing in the same markets alongside newer systems, with different chemistries, warranties and operating strategies. It is easy to see how differentiation will emerge as energy storage grows in future grid scenarios.

Solar+Battery in One Device Sets New Efficiency Standard

on July 21, 2020
Ars-Technica

The drop in battery prices is enabling battery integration with renewable systems in two contexts. In one, the battery serves as a short-term power reservoir to smooth over short-term fluctuations in the output of renewable power. In the other, the battery holds the power for when renewable power production stops, as solar power does at night. This works great for off-grid use, but it adds some complications in the form of additional hardware to convert voltages and current.

But there’s actually an additional option, one that merges photovoltaic and battery hardware in a single, unified device that can have extensive storage capacity. The main drawback? The devices have either been unstable or have terrible efficiency. But an international team of researchers has put together a device that’s both stable and has efficiencies competitive with those of silicon panels.

Solar flow batteries
How do you integrate photovoltaic cells and batteries? At its simplest, you make one of the electrodes that pulls power out of the photovoltaic system into the electrode of a battery. Which sounds like a major “well, duh!” But integration is nowhere near that simple. Battery electrodes, after all, have to be compatible with the chemistry of the battery—for lithium-ion batteries, for example, the electrodes end up storing the ions themselves and so have to have a structure that allows that.

So, the researchers used a completely different sort of chemistry. Flow batteries use solutions of two chemicals that can undergo charge-exchange reactions, shifting them between two chemical states. The battery basically borrows those charges in order to produce current when discharging, or it pumps charges back in to shift the chemicals to their alternate state, thus charging the battery. Flow batteries have the advantage that their total storage capacity is simply dependent upon the total volume of solution you use.

While there are many chemistries capable of working in a flow battery, the researchers started with their photovoltaic system and used that to choose the battery’s chemistry.

Even here, they didn’t exactly use off-the-shelf hardware. There was silicon involved, but it was part of a two-layer solar cell. In this setup, one photovoltaic material absorbs a set of wavelengths that aren’t absorbed by a second; the first layer, by contrast, is transparent to those wavelengths absorbed by the second. This allows a single cell to absorb a much broader range of wavelengths than would be possible otherwise, upping its overall efficiency.

For their device, the bottom layer was silicon. On top of that is a layer of perovskite photovoltaic material. Perovskites are a potential next-generation solar material, useful because they’re made from cheap ingredients and can be created simply by evaporating a solution of the perovskite. Unfortunately, these chemicals also have a propensity to decay, which has made for short lifetimes in many experimental setups. The researchers here don’t try to solve all of these problems; they simply use a perovskite-on-silicon photovoltaic setup and don’t try to run it for long enough that chemical decay is an issue.
