At its core, blockchain technology is a way to transfer any kind of data or information in a fast, tracked, and secure way without the need for an intermediary institution. Initially developed to allow peers to directly exchange digital currency faster and at lower cost, blockchain is now yielding a variety of promising new solutions beyond financial services.
The blockchain technology has attracted public interest as it provides an effective instrument to satisfy the needs of people to cooperate horizontally with each other in economic and social spheres like energy microgrids.
Blockchain technology is an innovative method of storing and validating data that permits direct transactions between energy producers and consumers.
We have to rush to limit climate change and to seize the economic opportunities that the transition entails. This WindWheel has released an architecture design for the wind turbine of the future
10 challenges we should overcome in order to transform successfully to a sustainable, strong and secure green energy economy.
Buildings, transport, industry, ICT, user behavior, energy storage, solar energy, wind energy, bio-energy, CO2 capture and more … Energy is one of the biggest changes in this century and has many aspects.
We present to you the ten important and urgent challenges, summarized by NERA. Read More
how to keep the climate comfortable in buildings, without energy-intensive installations
Do you also have dry eyes and headaches in your office building? This new Facade System allows a building to ‘breathe’. Tobias Becker used biomimicryfor a pleasant indoor climate.
The German engineer Ing. Tobias Becker has developed a glass facade system that requires minimal energy to generate a pleasant indoor climate. The system allows air through holes and makes buildings ‘breathe’. Read More
Shell has been operating in wind energy with 9 projects in North America and Europa, together 500MW of installed capacity.
Last May, Shell launched a new division for renewable energy, Martin Wetselaar, now responsible for integrated gas (including LNG), will lead the division ‘New Energy‘. Is Shell moving towards renewables?
The new division will be transferred to the existing activities in hydrogen, biofuels and renewable power generation. It will also be used as a basis for new activities in wind energy. Read More
Sam Molenaar believes that, with further optimization, the bacteria-based battery could rival the performance of lithium-ion batteries at a lower cost and with greater safety.
A rechargeable battery driven by bacteria? Lithium-ion batteries are limited by safety issues, high costs and other factors. Sam Molenaar and his colleagues from Wageningen University wanted to come up with a less expensive, more sustainable solution.
The research team combined two separate microbial energy systems. One system used bacteria to form acetate from electricity, while the other one converted the produced acetate back into electricity. Read More
Fusion proces: Because of a phenomenon known as quantum tunneling, the hydrogen atoms smash into each other and fuse into helium.
Is Fusion the answer for the new energy world? Scientists create hydrogen plasma, what the sun is made of.
Max Planck researchers finally succeeded in building this breakthrough reactor. And for the first time, the scientists have successfully created hydrogen plasma, the key component to nuclear fusion, and held it in a contained environment. Read More
“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 United States is the greatest risk, CarbonTracker states, with a cost of $ 412 billion in stranded assets “unnecessary fossil projects in 2025. Second in risk is Canada (220 billion). Than China (179 million), Russia (147 billion ) and Australia (US $ 103 billion).
The next decade fossil energy companies will lose possibly $ 2.2 trillion in investments, according CarbonTracker in a recent report.
When something is wrong with an energy meter, the SEC shows this in an alarm screen and you will get an automatic email
The Smart Energy Connector (SEC) is a very easy and sophisticated energy registration system for businesses. This plug&play system gives insights where, how much and how much energy is being used at any moment. 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.
the Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas by making use of both of the existing energy grids on a global scale
Power-to-Gas is the process of converting surplus renewable energy into hydrogen gas by rapid response electrolysis and its subsequent injection into the gas distribution network. One of the most promising energy storage systems to storage renewables into the existing EU gas infrastructure.
The hydrogen produced is injected into the natural gas system to displace natural gas, so reducing greenhouse gas emissions and reliance upon fuel imports.
If the power is derived mainly from renewable power sources, only low-carbon hydrogen will be produced. Thereby the Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas by making use of both of the existing energy grids on a global scale.
