Lithium is king of batteries, today. Plain and simple.

That’s, for today …

Wood Mackenzie reports that batteries made up 99 percent of [compound ] battery deployments at Q4 2018. 

Technology dominance is a understatement.

But nobody is ideal.

Hence, lithium batteries — with its six major chemistry variants — have problems with the following weaknesses.

Security — Overheating and exploding (“Uh, honeymy hoverboard is on fire. ”-RRB-
Duration — Maximum discharge length of four hours
Performance over time — 10-year life span, also round trip efficiency declines Costs — High energy density comes at a cost too high for mainstream use
Material accessibility — Uncertainty about lithium and cobalt (“Slavery in the distribution chain? No thank you. ”-RRB-

In reaction to these Achilles Heels’, entrepreneurs, angel investors, billionaires, venture capitalists, chemists, physicists, and even a former theology student (“God, help us? ”-RRB- are hard at work producing non-lithium battery solutions.

Three main Kinds of technology that are non-lithium are showing the most promise:

Thermal storage — that is, water heating (heaters) or heating (frequently into ice)
Flow batteries — typically between vanadium, but occasionally zinc or iron chemistries
Long term batteries — off-the-wall thoughts like molten salts or underground fluid compression

Can we actually need anything?

On one hand, the answer is no. 

Lithium-ion’s energy density and safety continue to increase, while its costs continue to decrease, roughly 85% because 2010. As the car market develops, it brings more lithium-ion manufacturing online to further lower costs and enhance performance. Regrettably, we’ve got no idea where the EV marketplace will property: Bloomberg sees EVs as 55 percent of new car sales globally in 2040, whereas OPEC and oil majors think the number is approximately 10%.

On the other hand, lithium won’t reduce it. 

With analysts projecting that solar and wind plants are more likely to get 73 percent of new power capacity investment internationally between now and 2050, we need to span days, weeks, or months together with stored power, not just minutes and minutes.

Case in point: From 2017 to 2018, Wood Mackenzie demonstrates that energy storage in the US grew by 44% concerning MW but 77 percent concerning MWh. The sector is demanding release durations. 

As their analyst Mitalee Gupta puts it“Four decades back, we weren’t talking about 4-hour duration. ” But today we’re speaking about 4 hours of release duration.

The marketplace for energy storage is changing rapidly. Forget about it, if you thought you understood it six or even twelve months before. It’s time to Combine with the most recent Lazard accounts on the Levelized Cost of Energy Storage, today on version 4.0, with new developments released each Fall.

For example, at 2017, they noted that lithium ’s 5-year price reduction could be 36 percent while circulation battery costs would drop 19% and 28 percent for vanadium and zinc bromide chemistries, respectively. 

However, the report shows the reverse: flow battery costs are projected to drop 38% and 45 percent, while costs may fall 28 percent.

To a degree that is to be anticipated: The speed of price decreases can’t continue to drop in exactly the same rate for a technology reaches maturity. 

By comparison, we are still in the first days of circulation battery creation and installation, and the corresponding price decreases that may come.

With Bloomberg projecting $620B spent in energy storage between this past year and 2040, there’s plenty of time and room for non-lithium technology to grab market share and develop into serious companies solving energy issues at scale. 

So which firms might lead that charge? Let’s have a peek …

In the event that you’re perplexed with any of the specialized terms within this discussion of next generation batteries, don’t worry. You’re . I’m with you.

But actually, who cares? Investors and job programmers don’t even need to be chemists or physicists. 

Instead, for storage technology to be set up, we simply need to understand that it does what it states it will, over a definite period of time, at the right price. 

And who knows, maybe insurance, not technology innovation, is going to be the alternative that substitutes “credit risk for tech risk” also makes non-lithum bankable. Contemplate headlines about Vionx Energy and ESS Energy Storage along those lines.
