Sustainer Homes

As you may noticed, Pushkar and me we are reporting quite often about pilot projects and plans on how to apply new knowledge on sustainability in the real world.

Today I would like to present you another project; the dream of everyone studying and working in the field of sustainability: Sustainer Homes, a house created by a startup from the Netherlands, that produces all the energy it needs out of local renewable energy sources.

As you can see in picture above, it is a 30 square meters container that originally were just normal transport containers. Isolation on the inside is made completely out of organic and recycled material, the wall color is anti-toxic and on a hemp basis.

The watersystem within the container and the heating system is powered by solar pannels that can generate up to 5 thousand kilowatts in one year, wind powered electricity generators and a rainwater collector that supplies fresh water. The generated electricity power gets stored in such that even in moments without wind and sun there is enough electricity left to supply the container with energy. Dark water gets filtered before it gets released into the environment.

And if I tell you that the price of this “house” you wont believe it: Only 75 thousand euros is what the designers want you to pay for this kind of accommodation. And the best thing, you will never ever have to pay for water, electricity, gas and all the other bills one has to pay.

Big thumbs up to lifegate.it for the original article, and an applause to Sustainer Homes that make such an incredible thing real.

Wind-to-Hydrogen: A possible solution to store energy?

If you follow our blog than you might know that one of the topics we discuss most is how to create energy in a sustainable way and how we can store that energy.

When electricity gets produced it has one big disadvantage: it has to be consumed when it gets produced. It is very difficult to store energy in big quantities. One possibility for the future could be what we discussed in one of our previous blog entries (HERE: Tesla lets you store energy at home) storing energy in a decentralized way.

Pumping water to higher places and use it when most needed is another way. But here i show you something even better: Using wind power to create hydrogen. In this article from derstandard.at, my favorite Austrian newspaper.

In a pilot project in Niederösterreich wind power gets used to create hydrogen trough electrolysis. Hydrogen is a high energy fuel, that can be used in different ways to get stored and then reused for energy production. The station build can produce up to 31 kg of hydrogen a day, consuming 50 liters of water/hour.

Right now the gained hydrogen can also be used to get mixed in the conventional natural gas pipelines, that allow a percentage of up to 5% mixture. But also cars could be powered with hydrogen.

The security aspect is not more difficult to handle than with other comparable substances. Hopefully this project shows that this is a way that has a bright future. Applied on a big scale this could be a realistic way to gain in energetic independence and in energetic sustainability.
