It can not be missed: we have to combat our CO2 emissions to stop climate change.
We have some news: Three scientific breakthroughs will enable us to quickly reduce these emissions according to venture investor Bill Joy. A pre-publication – including an update of the companies he mentions. Read More
Eco cities have a huge opportunity to impact the magnitude of climate exchange: after all, larger cities are consuming two thirds of the world’s energy and responsible for emitting over 70% of global CO2 emissions.
We analyzed the key objectives of the top 10 eco cities that were ranked highest in terms of environmental sustainability. Read More
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:
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
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.”

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.

IKEA has decided to invest an extra € 1 billion to tackle climate change, including investments in renewable energy.
Since 2009 the company has € 1.5 billion invested in wind and solar energy.
“We have got a very good year,” according to IKEA Group President and CEO Peter Agnefjäll at the presentation of the Annual Review and Sustainability Report of the past year. “As a result we have been able to continue significant investments in sustainability, improving our product portfolio and more increasing the number of our stores.”
The final declaration of the G20 summit in Antalya (Turkey) seems to be not an great start for the next climate summit in Paris. Especially India and Saudi Arabia will not cooperate. To limit the rise in global temperature to below two degrees Celsius, all countries must reduce greenhouse gas emissions.
Even after twenty hours of negotiations, both countries refused to agree a passage which included periodic monitoring of the reduction of greenhouse gas emissions.
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.
Since last weekend, the Virgin Islands, an archipelago in the Caribbean Sea, runs a sustainable desalination plant on solar power, designed by ‘Elemental Water Makers’.
Seldom I have seen people so grateful with a small contribution. I’m honest. Slightly less than 10 dollars. For a lot of StartUps this is normal nowadays. This one not. Class!

Jan van Liempt, director of In2Ecobuildings:
“The electronics industry makes perfect stuff for consumers: TVs, iPhones, sound equipment. Everything is made because customers want it. Clients get value for their money.
Any complains? Most of the times, it’s resolved perfectly. Why not for houses? Nor installations? That’s my passion. I build energy neutral buildings and I have learned that comfort in an energy neutral building is possible!”
For a period of two months, 25 streets in Ghent (Belgium) are transformed to the perfect play ground for kids.
The streets are closed to traffic.
The asphalt is covered with a green carpet. Neighbors made scattered tables and benches with wooden pallets. Street Live is returning, and even the opponents are turning – slowly.
Nowadays the traffic is too dangerous and parents are too afraid to let the children play outside.
In this Living Street, kids can play outside again.
