Hi Again,
Welcome to a new edition of the State of Charge Newsletter. A concise monthly overview of the renewable energy transition and the advent of electric mobility. This month we read about the ocean as a source of energy, we explore what driving an EV with a caravan does to your range, and we watch a clip that explains the politics behind the destruction of the Amazon 🌳.

SoC Big Story

The oceans cover 71 percent of the earth's surface, thus the potential of harvesting the power of waves to generate renewable energy is enormous. For many decades people have been working to achieve this, but there are still many technological, environmental and economic complexities that keep this technology from being used on a large scale. Today Hawaii is taking a massive step towards harvesting wave power on a large scale by connecting a newly built system to the grid. 🎉

The State of Charge September 2019

Every month we include an exclusive overview of the latest EV sales statistics from around the world. After a dip in July and August, September has seen a steep incline in the number of EVs sold.
State of Charge - Stats

These statistics only include 100% Electric Vehicles, no hybrids. Statistics are provided by our partner The Electric Vehicle World Sales Database.

SoC Must Read 

Between 1946 and 1958, the United States detonated 67 nuclear bombs on, in and above the Marshall Islands — vaporizing whole islands, carving craters into its shallow lagoons and exiling hundreds of people from their homes. After decades of experimenting the US build the Runit Dome, which harvests 3.1 million cubic feet by the US-produced radioactive soil and debris. Due to climate change, sea levels are rising, and the dome is showing decay which will lead to leakage of contaminated soil into the Enewetak Atoll and the surrounding ocean.

SoC Good Reads

Read up on the latest breakthrough in harvesting the energy of the sun with this emissions-free energy system, which saves heat from the summer sun for winter.

Are you thinking about switching to an electric vehicle but wonder what towing a caravan does to your range? Is it even possible to charge with an attached trailer or do you need to unhook it at every charging session? The Norsk Elbilforening had the same questions and decided to do the first electric vehicle test with caravans. You can find the article here.

SoC Deep Dive 

For this month's deep dive we take a look at a new technique that will significantly bring down the charging time of electric vehicles, something that for many people is still a reason not to buy one. In short, heating the battery to the perfect temperature allows for faster charging, cooling down the battery right after charging stops the battery from degrading. For a better explanation, find the article here, for the research article press the read more button.

SoC Other News

Electric mobility has taken off, and it is going nowhere but forward. This raises the issue of what to do with the batteries that power electric cars after they have retired. Why not use them for electric boats?

These pictures show a landscape straight out of a dystopian movie; sadly they are not. They were taken in Germany, where streams of an orange acid fluid are streaming out of mines.

In this newsletter, we have already mentioned a couple of new technologies that will help limit humanity's carbon emissions, either by emitting less or capturing it after the fact. But nature, of course, also provides us with many opportunities, like planting trees or restoring peatlands. And now new research has shown that whales—especially the great 🐳🐳—play a significant role in capturing carbon from the atmosphere.

SoC Listen to This

This month we listen to another interesting podcast from Engineering Matters, the podcast is hosted by Bernadette Ballantyne and highlights engineering solutions to global problems.

In this episode, she discusses the 2050 Carbon Calculator developed by late Cambridge professor David MacKay. This calculator allows anyone to calculate the impact of different energy scenarios on carbon and greenhouse gas emissions.
