Since the industrial revolution, we use cheap energy sources and special materials such as high strength concrete, carbon and mineral wool. The downside is an increasing use of fossil fuels and scarce earth materials, global warming and increasing environmental pollution. It is generally recognized that, in order to reverse this trend, we need to develop a circular economy.
Circular isolation materials can safely be composted or reused at a high quality level. Better for a healthy living and for our environment.
The circular economy aims to maximize the reuse of products and commodities and the prevention of value destruction.
Contrary to our current linear system, which transforms raw materials into products destroyed at the end of their lifespan. Read More
Eaton and Nissan said that, unlike Powerwall, xStorage will include professional installation and all requisite extras, such as cables.
Nissan and Eaton make home energy storage reliable and affordable to everyone with ‘xStorage’. Providing a sustainable ‘second life’ for Nissan’s electric vehicle (EV) batteries after their first life in cars is over.
The partners are collaborating to unveil a new residential energy storage unit. They intent to design the most affordable and reliable home power storage system for households. Read More
Miners use their bare hands to filter out precious minerals using a sluice. These countries can be compensated of we agree on international quotas for minerals
Critical minerals are running out too fast: there should be quotas
Last week, Theo Henckens has been promoted on this worrying thesis. “We need a kind of international agreement on minerals.”
Molybdenum is a mineral that is essential in the production of high-grade stainless steels. But within 80 years Earth will be running out of molybdenum, like many other major minerals. By the end of this century there will be a shortage, unless the reuse of molybdenum will be drastically increased. Read More
Aquion did come up with a breakthrough saltwater battery. It is environmentally friendly, cost effective and has a life cycle way beyond any other battery: up to 5,000 cycles.
The development of sustainable saltwater batteries enters the next level.
The American company Aquion Energy has received $ 33 million extra finance.
Previously, Bill Gates invested in Aquion Energy.
Aquion developed batteries that can store solar and wind energy to serve as backup for times when there is no wind nor sun. Saltwater batteries are not new, but the batteries from Aquion are special because they are using salt water as a conductor, instead of acids or bases.
Aquion has come up with a clever twist on a 200 year old salt water battery technology using:
Activated carbon (anode)
Manganese oxide (cathode)
And basically a salt water electrolyte
They have come up with a breakthrough solution. It is environmentally friendly, cost effective and has a life cycle way beyond any other battery: up to 5,000 cycles
So what’s Aquion’s energy storage innovation?
The startup — which was backed by Bill Gates and VCs like Kleiner Perkins and Foundation Capital — is making a low cost, modular grid battery made from basic materials like sodium and water.
The battery pairs a carbon anode with a sodium-based cathode, and a water-based electrolyte shuttles ions between the two electrodes during charging and discharging.
The technology was developed out of Carnegie Mellon University by founder and chief technology officer Jay Whitacre.
By using basic materials, Aquion is hoping its product is inexpensive enough to disrupt the current grid battery market.
Aquion’s CEO Scott Pearson:
“When the battery has been manufactured at a commercial scale for awhile, the price point of the battery could be $300 per kilowatt hour. That’s about a third of the cost of some of the more expensive lithium ion battery grid products.”
Saltwater batteries are tolerant to wide temperature ranges, partial state of charge cycling, and daily deep cycling with minimal degradation.
In addition to the safety and sustainability advantages of using water as electrolyte, another advantage is the thermal mass of the embodied water means that Aquion products neither heat nor cool rapidly. As such, the products can operate in a very wide operating temperature window because they simply take so long to heat and to cool.
The saltwater battery chemistry relies on charge/discharge mechanisms which are unaffected by partial state of charge – these batteries can sit indefinitely at partial, or even no state of charge, without irreversible capacity loss like lead acid batteries.
In June 2016, Aquion Energy has introduced the Aspen 24S, a 24-volt version of its award-winning Aqueous Hybrid Ion (AHI) battery.
The new product is designed for energy-intensive applications that use solar panels, such as off-grid solar-powered LED lighting, as well as small pumps and motors. It is also an ideal drop-in replacement for existing systems using 24-volt lead-acid batteries.
in 2014, companies in the electric transportation sector accounted for 820 million euro.
In 2014, the number of employments in electric vehicles increased by 25% to 3,200 jobs in the Netherlands.
Dutch companies in circular electric transport are doing a great job. National and international. Important, because they do not only contribute to our economy but they also are part of the solution to the global energy and climate issues. Read More
The approach of circular economy is: make – use – maintain/ reuse/ remanufacture/ recycle. Waste should be seen as source of valuable resources. Products should be repaired, remanufactured and reused. A genius idea in times when resources get scarce – be it oil, water or different metals and when the world has to face a growing population. It is estimated that 9.2 billion people will live on earth in 2050 (UN).
The world in 2050: That world is a fair, high-tech and sustainable one – with advances that mean food for all, a reformed capitalism, and a circular economy.
But the road getting there will not be easy.
The more I look at the two sides – the environment and the economy – the more convinced I become that the way forward is to fully integrate resource efficiency into the way we live and do business in the world.
We know why a circular economy is a good idea. At the moment the world is still locked into a linear production chain that is resource intensive. We obtain resources and then discard them as waste.
