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.

Tesla is Now the World’s Most Valuable Automaker

Thanks to a surging stock price, Tesla is now the world’s most valuable automaker – surpassing industry giants Toyota and Volkswagen.

Tesla is Now the World’s Most Valuable Automaker

Even in the midst of a pandemic, Tesla continues to reach new heights.

The company, which began as a problem-plagued upstart a little over 15 years ago, has now become the world’s most valuable automaker – surpassing industry giants such as Toyota and Volkswagen.

This milestone comes after a year of steady growth, which only hit a speed bump earlier this year due to COVID-19’s negative impact on new car sales. Despite these headwinds, Tesla’s valuation has jumped by an impressive 375% since this time last year.

How does Tesla’s value continue to balloon, despite repeated cries that the company is overvalued? Will shortsellers declare a long-awaited victory, or is there still open road ahead?

Tesla’s Race to the Top

Earlier this year, Tesla hit an impressive milestone, surpassing the value of GM and Ford combined. Since then, the automaker’s stock has continued it’s upward trajectory.

Thanks to the popularity of the Model 3, Tesla sold more cars in 2019 than it did in the previous two years combined:

As well, the company is taking big steps to up its production capacity.

Austin, Texas and Tulsa, Oklahoma are currently rolling out the incentives to attract Tesla’s new U.S.-based factory. The company is also increasing its global presence with the construction of Giga Berlin, it’s first European production facility, as well as completing the ongoing expansion of its Giga Shanghai facility in China.

Battle of the Namesakes

Tesla’s most recent price bump was fueled in part by a leaked internal memo from Tesla’s CEO, Elon Musk, urging the company’s staff to go “all out” on bringing electric semi trucks to the global market at scale.

It’s time to go all out and bring the Tesla Semi to volume production.

– Elon Musk

Of course, Musk’s enthusiasm for semi trucks isn’t coming from nowhere. Another company, Nikola (also named after famed inventor Nikola Tesla), is focused on electrifying the two million or so semi trucks in operation in the U.S. market.

Although Nikola has yet to produce a vehicle, its market cap has surged to $24 billion – which puts its valuation nearly on par with Ford. Much like Tesla, the company already has preorders from major companies looking to add electric-powered trucks to their delivery fleets.

For major brands looking to hit ESG targets, zero-emission heavy-duty trucks is an easy solution, particularly if the vehicles also live up to claims of being cheaper over the vehicle’s lifecycle. The big question is which automaker will capitalize on this mega market first?

6 Ways Hydrogen and Fuel Cells Can Help Transition to Clean Energy

Here are six reasons why hydrogen and fuel cells can be a fit for helping with the transition to a lower-emission energy mix.

Published

on

Hydrogen and fuel cells

While fossil fuels offer an easily transportable, affordable, and energy-dense fuel for everyday use, the burning of this fuel creates pollutants, which can concentrate in city centers degrading the quality of air and life for residents.

The world is looking for alternative ways to ensure the mobility of people and goods with different power sources, and electric vehicles have high potential to fill this need.

But did you know that not all electric vehicles produce their electricity in the same way?

Hydrogen: An Alternative Vision for the EV

The world obsesses over battery technology and manufacturers such as Tesla, but there is an alternative fuel that powers rocket ships and is road-ready. Hydrogen is set to become an important fuel in the clean energy mix of the future.

Today’s infographic comes from the Canadian Hydrogen and Fuel Cell Association (CHFCA) and it outlines the case for hydrogen.

6 Ways Hydrogen and Fuel Cells Can Help Transition to Clean Energy

Hydrogen Supply and Demand

Some scientists have made the argument that it was not hydrogen that caused the infamous Hindenburg to burst into flames. Instead, the powdered aluminum coating of the zeppelin, which provided its silver look, was the culprit. Essentially, the chemical compound coating the dirigibles was a crude form of rocket fuel.

Industry and business have safely used, stored, and transported hydrogen for 50 years, while hydrogen-powered electric vehicles have a proven safety record with over 10 million miles of operation. In fact, hydrogen has several properties that make it safer than fossil fuels:

  • 14 times lighter than air and disperses quickly
  • Flames have low radiant heat
  • Less combustible
  • Non-toxic

Since hydrogen is the most abundant chemical element in the universe, it can be produced almost anywhere with a variety of methods, including from fuels such as natural gas, oil, or coal, and through electrolysis. Fossil fuels can be treated with extreme temperatures to break their hydrocarbon bonds, releasing hydrogen as a byproduct. The latter method uses electricity to split water into hydrogen and oxygen.

Both methods produce hydrogen for storage, and later consumption in an electric fuel cell.

Fuel Cell or Battery?

Battery and hydrogen-powered vehicles have the same goal: to reduce the environmental impact from oil consumption. There are two ways to measure the environmental impact of vehicles, from “Well to Wheels” and from “Cradle to Grave”.

Well to wheels refers to the total emissions from the production of fuel to its use in everyday life. Meanwhile, cradle to grave includes the vehicle’s production, operation, and eventual destruction.

According to one study, both of these measurements show that hydrogen-powered fuel cells significantly reduce greenhouse gas emissions and air pollutants. For every kilometer a hydrogen-powered vehicle drives it produces only 2.7 grams per kilometer (g/km) of carbon dioxide while a battery electric vehicle produces 20 g/km.

During everyday use, both options offer zero emissions, high efficiency, an electric drive, and low noise, but hydrogen offers weight-saving advantages that battery-powered vehicles do not.

In one comparison, Toyota’s Mirai had a maximum driving range of 312 miles, 41% further than Tesla’s Model 3 220-mile range. The Mirai can refuel in minutes, while the Model 3 has to recharge in 8.5 hours for only a 45% charge at a specially configured quick charge station not widely available.

However, the world still lacks the significant infrastructure to make this hydrogen-fueled future possible.

Hydrogen Infrastructure

Large scale production delivers economic amounts of hydrogen. In order to achieve this scale, an extensive infrastructure of pipelines and fueling stations are required. However to build this, the world needs global coordination and action.

Countries around the world are laying the foundations for a hydrogen future. In 2017, CEOs from around the word formed the Hydrogen Council with the mission to accelerate the investment in hydrogen.

Globally, countries have announced plans to build 2,800 hydrogen refueling stations by 2025. German pipeline operators presented a plan to create a 1,200-kilometer grid by 2030 to transport hydrogen across the country, which would be the world’s largest in planning.

Fuel cell technology is road-ready with hydrogen infrastructure rapidly catching up. Hydrogen can deliver the power for a new clear energy era.
