In windy regions like the north of Europe, the challenge is to store all the green windmill electricity.
Of course the large amounts of electricity can be stored in batteries but Denmark, the Netherlands and Germany are investing in hydrogen to store the energy.
During reel-out, the kite is flying figure-eight maneuvers at high speed (70 to 90 km/h). This creates a high traction force (3.1 kN at 7 m/s wind speed) which is converted into electricity by the drum and the connected 20 kW generator.
Kite Power by harnessing high altitude wind next step in Dutch Icon project ‘Afsluitdijk’.
Even NASA has started to work on airborne wind energy. This field is very new and has much room for innovation.
Flight testing with actual consistent measured power production is the next step.
If this large-scale storage of renewable energy in liquid ammonia succeeds, communities can cover long low wind and solar energy periods
Is liquid Ammonia the solution for energy storage?
Big energy company Nuon, together with the Technical University Delft started a pilot project in which renewable energy will be stored in liquid ammonia. Read More
The challenge we face is big, perhaps bigger than many people imagine. But so is the opportunity. If the world can find a source of cheap, clean energy, it will do more than halt climate change. It will transform the lives of millions of the poorest families.
Every year, Bill Gates writes a letter to students.
This year’s letter is about our climate and energy transition towards a renewable energy world.
In his letter, he notices that that all plans and existing techniques will not be sufficient enough to stop the global warming.
This year, Gates appeals to the students of today. Read More
Green affortable desalination technology Virgin Islands, using gravitation
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’.
The Wind Lens could deliver even five times more power than conventional turbines
Japanese researchers have created a technology called “Wind Lens” that at least triples the potential output of a wind turbine.
The Wind Lens is a source of renewable energy that Japan has been introducing since the earthquake and tsunami of 2011.
Imagine: our entire society powered by the quiet “woosh” of a wind turbine. Kyushu University‘s Wind Lens Turbine is one example of the many innovations happening right now that could transform our world in a green world. Read More
Of all the Australian states, the South has the most wind and solar capacity per person. Wind power generates electricity equal to about a third of the state’s total consumption and rooftop solar generates about 6%. All up, South Australia gets about 40% of its electricity from wind and solar. Read More
Renewable energy: in a 33% renewable scenario on the western grid there is a net savings of over $6.8 billion dollars each year
From a system perspective, wind and solar can increase annual operating costs for fossil-fueled generators by $35 million to $157 million, while reducing fuel costs by $7 billion reports NREL.
Bill Gates and Jigar Shah started an excellent discussion – and good science should spark debate. But, when determining policies pertaining to emissions reductions – for the electricity or any other sector – the scope needs to be long term because climate change is a long-term issue. Read More
This WavePower Generator mini-model is the first to use the whole elliptic way of movement of the waves. And by that takes the full advantage of the wave energy in order to produce electricity.Fully patented, the most efficient device for producing electricity from wave’s energy.
The wave energy potential is
10 times greater than wind energy
more than 100 times greater than solar energy
The WavePower generator is capable of gathering almost 30% of the waves energy potential.
Maintenance and repair costs
Prior calculations show that the total cost of energy (financing, building and maitenance) for 20 years should be around USD 0.02/KWh.
