Our Energy Problem: Putting the Battery in Context

In Part 1, we examined the evolution of battery technology. In this part, we examine what batteries can and cannot do, and the energy problem that humans hope that batteries can help solve.

Batteries enable many important aspects of modern life.

They are portable, quiet, compact, and can start-up with the flick of a switch. Importantly, batteries can also store energy from the sun and wind for future use.

However, batteries also have many limitations that prevent them from taking on an even bigger role in society. They must be recharged, and they hold a limited amount of energy. A single battery cycle is only so long, and after many of them they begin to lose potency.

Therefore, to understand the market for batteries and how it may look in the future, it is essential to understand what a battery can and cannot do.

Energy Density

The biggest difference between batteries and other fuel types is in energy density.

Even the best lithium-ion batteries have a specific energy of about 250 Wh/kg. That is just 2% of the energy density of gasoline, and less than 1% of hydrogen.

While it may be enough to power a car, it’s also magnificent engineering that helps makes this possible. Airplanes, ships, trains, and other large power drains will not be using batteries in powertrains anytime soon.

A Renewable Future?

Renewable energy sources like solar and wind face a similar problem – today’s battery technology cannot store big enough payloads of energy. To balance the load, excess energy must be stored somehow to be used when the sun isn’t shining and the wind isn’t blowing.

Currently, industrial-strength battery systems are not yet fully developed to handle this storage problem on a widespread commercial basis, though progress is being made in many areas. New technologies such as vanadium flow batteries could play an important role in energy storage in the future. But for now, large-scale energy storage batteries are experimental.

Other energy storage technologies may also solve this problem:

  • Chemical storage: Using excess electricity to create hydrogen fuel, which can be stored.
  • Pumped hydro: Using electricity to pump water up to a reservoir, which can be later used to generate hydroelectric power.
  • Compressed air: Using electricity to compress air in deep caverns, which can be released to generate power.

Solving this energy storage problem will pave the way for more use of renewables in the future on a grander scale.

The Sweet Spot

Therefore, the sweet spot for battery use today comes when batteries can take advantage of their best properties. Batteries can be small, portable, charged on the go, and provide energy at the flick of a switch.

It’s why so many rechargeable batteries are used in: electronics, laptops, smartphones, electric cars, power tools, startup motors, and other portable items that can benefit from these traits.

To assess the suitability of a particular type for any specific use, there are 10 major properties worth looking at:

  • High Specific Energy: Specific energy is the total amount of energy stored by a battery. The more energy a battery can store, the longer it can run.
  • High Specific Power: Specific power is the amount of load current drawn from the battery. Without high specific power, a battery cannot be used for the high-drain activities we need
  • Affordable Cost: If the price isn’t right for a particular battery type, it may be worth using an alternative fuel source or battery configuration for economic reasons
  • Long Life: The chemical makeup of batteries isn’t perfect. As a result, they only last for a number of charge/discharge cycles – if that number is low, that means a battery’s use may be limited.
  • High Safety: Batteries are used in consumer goods or for important industrial or government applications – none of these parties want batteries to cause safety issues.
  • Wide Operating Range: Some chemical reactions don’t work well in the cold or heat – that’s why it’s important to have batteries that work in a range of temperatures where it can be useful.
  • No Toxicity: Nickel cadmium batteries are no longer used because of their toxic environmental implications. New batteries to be commercialized must meet stringent standards in these regards.
  • Fast Charging: What good would a smartphone be if it took two full days to recharge? Charge time matters.
  • Low Self-Discharge: All batteries discharge small amounts when left alone over time – the question is how much, and does it make an impact on the usability of the battery?
  • Long Shelf Life: The shelf life of batteries affects the whole supply chain, so it is important that batteries can be usable many years after being manufactured.

There are many pros and cons to consider in choosing a battery type. The more pros that a given battery technology can check off the above list, the more likely it is to be commercially viable.

Now that you know what batteries can and cannot do, we will now look at the rechargeable battery market in Part 3 of the Battery Series.

At an average $11.10 per gallon, households in Hong Kong pay the highest for gasoline in the world—more than double the global average. Both high gas taxes and steep land costs are primary factors behind high gas prices.

Like Hong Kong, the Central African Republic has high gas costs, at $8.60 per gallon. As a net importer of gasoline, the country has faced increased price pressures since the war in Ukraine.

Households in Iceland, Norway, and Denmark face the highest gasoline costs in Europe. Overall, Europe has seen inflation hit 10% in September, driven by the energy crisis.

2. Global Energy Prices: Electricity

Extreme volatility is also being seen in electricity prices.

The majority of the highest household electricity prices are in Europe, where Denmark, Germany, and Belgium’s prices are about double that of France and Greece. For perspective, electricity prices in many countries in Europe are more than twice or three times the global average of $0.14 per kilowatt-hour.

Over the first quarter of 2022, household electricity prices in the European Union jumped 32% compared to the year before.

In the U.S., consumer electricity prices have increased nearly 16% annually compared to September last year, the highest increase in over four decades, fueling higher inflation.

However, households are more sheltered from the impact of Russian supply disruptions due to the U.S. being a net exporter of energy.

3. Global Energy Prices: Natural Gas

Eight of the 10 highest natural gas prices globally fall in Europe, with the Netherlands at the top. Overall, European natural gas prices have spiked sixfold in a year since the invasion of Ukraine.

The good news is that the fall season has been relatively warm, which has helped European natural gas demand drop 22% in October compared to last year. This helps reduce the risk of gas shortages transpiring later in the winter.

Outside of Europe, Brazil has the fourth highest natural gas prices globally, despite producing about half of supply domestically. High costs of cooking gas have been especially challenging for low-income families, which became a key political issue in the run-up to the presidential election in October.

Meanwhile, Singapore has the highest natural gas prices in Asia as the majority is imported via tankers or pipelines, leaving the country vulnerable to price shocks.

Increasing Competition

By December, all seaborne crude oil shipments from Russia to Europe will come to a halt, likely pushing up gasoline prices into the winter and 2023.

Concerningly, analysis from the EIA shows that European natural gas storage capacities could sink to 20% by February if Russia completely shuts off its supply and demand is not reduced.

As Europe seeks out alternatives to Russian energy, higher demand could increase global competition for fuel sources, driving up prices for energy in the coming months ahead.

Still, there is some room for optimism: the World Bank projects energy prices will decline 11% in 2023 after the 60% rise seen after the war in Ukraine in 2022.

Visualizing the World’s Largest Hydroelectric Dams

Hydroelectric dams generate 40% of the world’s renewable energy, the largest of any type. View this infographic to learn more.



Visualizing the World’s Largest Hydroelectric Dams

This was originally posted on Elements. Sign up to the free mailing list to get beautiful visualizations on natural resource megatrends in your email every week.

Did you know that hydroelectricity is the world’s biggest source of renewable energy? According to recent figures from the International Renewable Energy Agency (IRENA), it represents 40% of total capacity, ahead of solar (28%) and wind (27%).

This type of energy is generated by hydroelectric power stations, which are essentially large dams that use the water flow to spin a turbine. They can also serve secondary functions such as flow monitoring and flood control.

To help you learn more about hydropower, we’ve visualized the five largest hydroelectric dams in the world, ranked by their maximum output.

Overview of the Data

The following table lists key information about the five dams shown in this graphic, as of 2021. Installed capacity is the maximum amount of power that a plant can generate under full load.

CountryDamRiverInstalled Capacity
🇨🇳 ChinaThree Gorges DamYangtze River22.5181 x 2,335
🇧🇷 Brazil / 🇵🇾 ParaguayItaipu DamParana River14.0196 x 7,919
🇨🇳 ChinaXiluodu DamJinsha River13.9286 x 700
🇧🇷 BrazilBelo Monte DamXingu River11.290 X 3,545
🇻🇪 VenezuelaGuri DamCaroni River10.2162 x 7,426

At the top of the list is China’s Three Gorges Dam, which opened in 2003. It has an installed capacity of 22.5 gigawatts (GW), which is close to double the second-place Itaipu Dam.

In terms of annual output, the Itaipu Dam actually produces about the same amount of electricity. This is because the Parana River has a low seasonal variance, meaning the flow rate changes very little throughout the year. On the other hand, the Yangtze River has a significant drop in flow for several months of the year.

For a point of comparison, here is the installed capacity of the world’s three largest solar power plants, also as of 2021:

  • Bhadla Solar Park, India: 2.2 GW
  • Hainan Solar Park, China: 2.2 GW
  • Pavagada Solar Park, India: 2.1 GW

Compared to our largest dams, solar plants have a much lower installed capacity. However, in terms of cost (cents per kilowatt-hour), the two are actually quite even.

Closer Look: Three Gorges Dam

The Three Gorges Dam is an engineering marvel, costing over $32 billion to construct. To wrap your head around its massive scale, consider the following facts:

  • The Three Gorges Reservoir (which feeds the dam) contains 39 trillion kg of water (42 billion tons)
  • In terms of area, the reservoir spans 400 square miles (1,045 square km)
  • The mass of this reservoir is large enough to slow the Earth’s rotation by 0.06 microseconds

Of course, any man-made structure this large is bound to have a profound impact on the environment. In a 2010 study, it was found that the dam has triggered over 3,000 earthquakes and landslides since 2003.

The Consequences of Hydroelectric Dams

While hydropower can be cost-effective, there are some legitimate concerns about its long-term sustainability.

For starters, hydroelectric dams require large upstream reservoirs to ensure a consistent supply of water. Flooding new areas of land can disrupt wildlife, degrade water quality, and even cause natural disasters like earthquakes.

Dams can also disrupt the natural flow of rivers. Other studies have found that millions of people living downstream from large dams suffer from food insecurity and flooding.

Whereas the benefits have generally been delivered to urban centers or industrial-scale agricultural developments, river-dependent populations located downstream of dams have experienced a difficult upheaval of their livelihoods.
– Richter, B.D. et al. (2010)

Perhaps the greatest risk to hydropower is climate change itself. For example, due to the rising frequency of droughts, hydroelectric dams in places like California are becoming significantly less economical.
