Gravitricity: Fast, Versatile Energy Storage Solution: UK
Globally, we are generating more electricity from intermittent renewable energy sources than ever before. We are slowly making steps to a decarbonized world, but for our renewable energy, we are still reliant on weather-dependent sources, like marine, wind, and solar. We will need new technologies to capture and store energy during periods of low demand and with a quick release when needed. The idea of the British start-up Gravitricity almost seems too good to be true. By using enormous weights, the company wants to turn mine shafts into low-cost energy storage systems – with 'some of the best characteristics of lithium batteries and pumped storage.' Is this the large-scale electricity storage the world needs, or is it, in fact, too good to be true? The concept seems to be so simple. Gravitricity describes their innovative technology as a huge 'clock weight.' "A cylindrical weight of 500 - 5000 tonnes is suspended in a deep (preferably already existing) shaft by a number of cables each of which is engaged with a winch capable of lifting its share of the weight. Electrical power is then absorbed or generated by raising or lowering the weight. The weight is guided by a system of tensioned guide wires (patents applied for) to prevent it from swinging and damaging the shaft. The winch system can be accurately controlled through the electrical drives to keep the weight stable in the hole."  Gravitricity: Fast, Versatile Energy Storage Solution Like A Dream The target groups are network-constrained users and operators, distribution networks, and major power users. The technology operates in the 1MW to 20 MW power range. With a design life of fifty years, response time from zero to full power in less than one second and efficiency between 80 and 90 percent, Gravitricity seems like a dream. It is a way to utilize existing mines or purpose-built shafts. ‘Future deployments will be able to utilize existing mines or purpose-built shafts, allowing development wherever storage is required,’ according to Gravitricity.

The Illusions Of Renewables. Solar And Wind Will Not Save Our Climate
Far too often, the debate on climate change shifts to one of fossil fuels versus renewable energy. If we were to completely let go of the ‘wasteful’ and switch to energy generated by natural elements such as wind, solar or waves, it would - or so it is alleged - save our planet. This thought has been at the center of the climate debate for more than 30 years, setting in motion large-scale renewable energy projects. However, looking at today’s landscape, we see that there isn’t a single nation that has completely shifted its energy needs to renewable sources. Some Scandinavian countries are well underway to realising a near-zero carbon electricity supply, but what stands out here, is the fact that renewables like solar and wind only make up a small percentage of this. It is a well-documented fact that the number of solar panels or wind turbines required to even come close to the amount of energy generated by ‘regular’ producers is massive. At the same time, these enormous grids required will lead to higher costs of generating electricity, huge amounts of energy required for its production, and leave behind a large environmental footprint. Additionally, it is a rather unreliable source of energy.   In short, solar and wind energy are not just falling short of what they ought to be producing in order to be an adequate replacement, they are also largely unnecessary when looking at the bigger picture. Which will, eventually, really be a good thing. Renewables history When listening to a regular climate change debate, one will be quick to conclude that renewable energy - in particular solar and wind energy - is a relatively new invention. Wind turbines have, after all, not been recorded in modern history as a common sight until recently. Yet the reality is that wind and sunlight are some of the oldest sources of energy that we have. Already back in 1833, a man named John Etzler was involved in a proposal that sought to construct solar power plants. These would employ mirrors to concentrate sunlight on boilers. Solar panels that are capable of generating electricity have even been mentioned in literature back in the late 1800s. The schools of thought were there, waiting to be picked up - but unfortunately being overrun by the power of coal and other fossil fuels. Yet renewables were never far from our mind, as there have been numerous mentions of solar energy in publications throughout the 20th century - pointing at it as the next ‘big thing’ in power generation. This started in 1891, with The New York Times reporting that solar energy is not yet economical in an article titled “ Solar Energy: What the Sun's Rays Can Do and May Yet Be Able to Do ”, in which it concluded "… the day is not unlikely to arrive before long… ”. Solar and wind energy revolution! Did it arrive? That day did arrive, yet it never really ‘caught on’, despite the hype being attributed to it by journalists and experts alike. In 1931, another journalist of The New York Times had discovered this ‘hidden treasure’, writing about “ the evolution of civilization similar to that which followed the invention by James Watt of the steam engine ”. In the following decades, renewables slowly got more attention and found themselves at the center of scientific and political debate, with subsidies, tax cuts and grants being thrown at it. Especially around the turn of the century, it seemed as if the ‘big breakthrough’ was waiting to happen - only waiting on that last bit of funding. A massive $2 trillion was spent on wind and solar energy combined between 2007 and 2016, according to Bloomberg New Energy Finance, with governments spending up to 100 times more on its subsidies than it did for nuclear and fossil fuels.   The results? Far from as impressive: in 2016, solar and wind generated energy only made up 1.3 and 3.9 percent of the earth’s total, respectively. ( Recommended :  Vortex Wind Turbine: Energy Generator Without Blades ) Denmark and Germany as role model? Of course, these numbers above are merely an average. Some countries, like Denmark, show more promising numbers for its decarbonisation process: where wind energy in particular is thriving, making up 48 percent of the total electricity in the country. Does this make them the role model for renewables that we need to create a blueprint for other countries as well? Well, it is important to understand the specific reasons why this tiny Scandinavian country was able to achieve this. Firstly, it is small. Really small. It has fewer than 6 million inhabitants, occupies a piece of land that can be crossed in only a few hours, and is a minor player on the world’s economic stage.   While small, it is located in a favourable region, with many European neighbours willing to import the excess wind energy generated, lowering the risk of a costly surplus. Regardless, Denmark’s electricity prices are still amongst the highest in the world. And while this is justified by claiming that the industry is one of its most important export products, it is still striking.   Areas that are deploying solar energy on a large scale have seen similar uptakes in electricity price. Denmark’s neighbour Germany has long boasted a status as the poster child of renewables, but is facing similar issues. Their electricity is the second most expensive in Europe, after Denmark, while emissions are not declining as much as they would like.   Danish Tax Minister Karsten Lauritzen said that the Government should rethink the level of tax on electricity consumption, which is currently the highest in Europe. According to the Tax Ministry, approximately 40 percent of a household electricity bill is tax but these revenues were and are nessecarry in Denmmark to subsidize the development of renewable energy. Carbon emissions least production: France and Sweden Therefore, measuring the share of solar and wind based energy sources in the total energy production will paint a somewhat misleading image - and show the inefficiency of solar and wind. A much better benchmark can be found when looking at the amount of carbon emissions per capita. Here, France and Sweden are ranking high. The surprising thing? While those countries have successfully cut their carbon emissions, they have done so by employing only limited wind and solar sources. Sweden is deriving 95 percent of its electricity from zero-carbon sources, and France 88 percent. What these sources are? Nuclear and hydroelectric power. Other countries, including Norway, Brazil and Costa Rica, have harnessed hydroelectric power in a similar fashion, effectively decarbonising their economies. Nuclear is slightly more scalable and reliable, compared to hydroelectricity’s relatively large environmental impact. Hydroelectricity, as demonstrated by Brazil and California, is inherently unreliable and will not let itself be steered, meaning that countries will have to fall back on fossil fuels if production unexpectedly falls short. Thus, nuclear energy appears to be the only zero-carbon source that is capable of saving our planet - it is scalable, reliable, and efficient. Renewables not necessary to save the climate   Good news, so far: we do not need renewables to solve climate change. Renewables require a lot of land and specific wasteful ‘ingredients’ like concrete, steel and glass for its production - nuclear plants only need a fraction of this.   {youtube}                                              The Illusions Of Renewables. Solar And Wind Will Not Save Our Climate To demonstrate this: solar panels have been shown to rake up to 300 times more toxic waste than nuclear energy. And even after having been produced in a wasteful manner, they still harm the environment by occupying large areas of land, threatening the local ecosystem - all in exchange for a relatively minor share of electricity. ( Recommended :  Solar Farms In Space: Next Step In Renewable Energy ) Are we headed for a solar waste crisis? While people are up in arms about nuclear waste, only very few really seem to be concerned about the concept of solar waste. And solar waste there is: most countries do not have an adequate plan for safely disposing this often toxic waste, while its pile is growing steadily. Nuclear waste makes all the alarm bells in our heads go off, while solar waste seems to be regarded with something akin to indifference. Solar waste versus nuclear   Let’s start with some cold, hard facts. Every unit of energy generated by solar creates 3000 times more toxic waste than a unit of energy generated by nuclear energy. To put it in a perspective that hits home: Environmental Progress calculated that, if all waste generated over the next 25 years would be stacked on a football field, the pile of nuclear waste would be about the same height as the Leaning Tower of Pisa (52 meters), while the solar waste pile would be as high as two Mt. Everests (16 km). Developing countries, on the other hand, are facing similar issues. China, India and Ghana are dealing with those living in communities near waste dumps. Here, waste is often burned in an attempt to salvage copper wires, which are consequently resold. This process requires the burning of surrounding plastics, meaning that the smoke that is released is very harmful and straight-up toxic to human health. Nuclear waste, on the other hand, is carefully stored and managed. Using the highest levels of caution and safety, waste is contained in cement-filled drums and stored in secured facilities for decades or even centuries on end. When comparing this to the lacklustre way in which solar waste is simply ‘dumped atop the pile’ of electronic waste, it is not hard to see where we are doing something wrong. Solar panels contain a large number of dangerous materials, including lead, chromium and cadmium - not just harmful on direct impact, but also potentially capable of infiltrating drinking water supplies.   Actual dangers versus perceived dangers The dilemma is not as tough when carefully observing those facts. The share of nuclear energy in the world’s electricity market is larger, yet created using ‘less’. Less waste, less land area, less of an ecological and environmental footprint. While we are keen on implementing more solar and wind, the reality is that these energy sources are often showing far from rosy numbers below the line.   We would do well to move beyond this illusion of renewables and explore other zero-carbon sources of energy, in particular nuclear energy. There are relatively few drawbacks to this stable and secure source of energy, that has remained at the center of societal scrutiny since its earlier days. Nuclear energy is one way of tackling climate change in a meaningful manner - something that unfortunately cannot be said about wind or solar. It is time to make decisions based on facts rather than on dreams of renewables. Recomended: Man-Made Climate Change

Solar Farms In Space: Next Step In Renewable Energy
The green energy revolution continues to accelerate - solar parks are a familiar sight all over the world. But China wants to take solar energy to a whole new level. The nation’s ambition is to put a solar power station in orbit by 2050. With this power station, China will have access to the most reliable source of renewable energy, since the sun always shines in space. If this difficult and costly plan will work, it will make China the first nation to harness the sun’s energy in space and beam it to Earth. Are solar farms in spaces the answer to our prayers or a mission impossible? Solar energy: the inexhaustible source It seems to be a great idea: space-based solar power as an inexhaustible source of energy. "You don’t have to deal with the day and night cycle, and you don’t have to deal with clouds or seasons, so you end up having eight to nine times more power available to you," said Ali Hajimiri, a professor of electrical engineering at the California Institute of Technology and director of the university’s Space Solar Power Project for solar farms in space. ( Recommended: Solar Energy Turned Into Liquid Fuel Can Be Stored For 18 Years ) Energy demands So why haven’t anyone thought of this before? Well, the thought of using solar farms in space is nothing new. The idea was very vivid in the 1970s. The research stalled largely because the technological demands of a solar power station in space were thought to be too complex. But nowadays, there is a huge progression in technology compared to a few years ago. The improvements in the design and efficiency of photovoltaic cells and advances in wireless transmission are making it possible to pick up where researchers left off. How much of a difference will these improvements make? Asked John Mankins, a physicist who led the agency’s efforts in the field in the 1990s before NASA abandoned the investigating. “We’re seeing a bit of a resurgence now, and it’s probably because the ability to make solar farms in space is there, thanks to new technologies."   According to Mankins, there is another factor driving the revived interest in this kind of renewable power. The world’s population is growing – it’s expected to swell to 9 billion by 2050. Space-based solar power can become essential to meet the energy demands of people in parts of the world that aren’t particularly sunny. “If you look at the next 50 years, the demand for energy is stupendous. If you can harvest sunlight with solar farms in space where the sun is always shining and deliver it with essentially no interruptions to Earth — and you can do all that at an affordable price, you win." {youtube}                                                                       Solar Farms In Space: Next Step In Renewable Energy                                                                                Mission impossible? Details of China’s plan remain a secret. According to Mankins, the nation can 'launch tens of thousands of 'solar satellites' that would link up to form an enormous cone-shaped structure that orbits about 22,000 miles above Earth. They would be covered with photovoltaic panels to convert sunlight into energy, which would be beamed wirelessly to ground-based receivers. Such a solar facility could generate a steady flow of 2,000 gigawatts of power.’ There are still some hurdles to overcome, like the weight of the solar panels. ( Recommended: Waste In Space Will Be Fetched By The Cubesail carbage Truck ) It will also cost billions of dollars to make these solar farms in space happen. The research, the tests and the solar satellites itself (price tag: about ten billion each) will make this a very expensive project – to say the least. China hasn’t revealed how much it’s spending to develop its solar power stations, but the China Daily reported that the nation is already building a test facility in the southwestern city of Chongqing. It doesn’t seem like a mission impossible. China is taking a key position in the development of solar farms in space. According to John Mankins, a solar power station in space is a wonderful thing. “For a lot of locations, rooftop solar is fabulous, but a lot of the world is not like Arizona (or other sunny places). Millions of people live where large, ground-based solar arrays are not economical,” he said. Mankins hailed recent developments in the field and said he is keen to follow China’s new initiative. What do you think - is this next step in renewable energy? ( Recommended: All About Solar Energy )
The green energy revolution continues to accelerate - solar parks are a familiar sight all over the world. But China wants to take solar energy to a whole new level. The nation’s ambition is to put a solar power station in orbit by 2050. With this power station, China will have access to the most reliable source of renewable energy, since the sun always shines in space. If this difficult and costly plan will work, it will make China the first nation to harness the sun’s energy in space and beam it to Earth. Are solar farms in spaces the answer to our prayers or a mission impossible? Solar energy: the inexhaustible source It seems to be a great idea: space-based solar power as an inexhaustible source of energy. "You don’t have to deal with the day and night cycle, and you don’t have to deal with clouds or seasons, so you end up having eight to nine times more power available to you," said Ali Hajimiri, a professor of electrical engineering at the California Institute of Technology and director of the university’s Space Solar Power Project for solar farms in space. ( Recommended: Solar Energy Turned Into Liquid Fuel Can Be Stored For 18 Years ) Energy demands So why haven’t anyone thought of this before? Well, the thought of using solar farms in space is nothing new. The idea was very vivid in the 1970s. The research stalled largely because the technological demands of a solar power station in space were thought to be too complex. But nowadays, there is a huge progression in technology compared to a few years ago. The improvements in the design and efficiency of photovoltaic cells and advances in wireless transmission are making it possible to pick up where researchers left off. How much of a difference will these improvements make? Asked John Mankins, a physicist who led the agency’s efforts in the field in the 1990s before NASA abandoned the investigating. “We’re seeing a bit of a resurgence now, and it’s probably because the ability to make solar farms in space is there, thanks to new technologies."   According to Mankins, there is another factor driving the revived interest in this kind of renewable power. The world’s population is growing – it’s expected to swell to 9 billion by 2050. Space-based solar power can become essential to meet the energy demands of people in parts of the world that aren’t particularly sunny. “If you look at the next 50 years, the demand for energy is stupendous. If you can harvest sunlight with solar farms in space where the sun is always shining and deliver it with essentially no interruptions to Earth — and you can do all that at an affordable price, you win." {youtube}                                                                       Solar Farms In Space: Next Step In Renewable Energy                                                                                Mission impossible? Details of China’s plan remain a secret. According to Mankins, the nation can 'launch tens of thousands of 'solar satellites' that would link up to form an enormous cone-shaped structure that orbits about 22,000 miles above Earth. They would be covered with photovoltaic panels to convert sunlight into energy, which would be beamed wirelessly to ground-based receivers. Such a solar facility could generate a steady flow of 2,000 gigawatts of power.’ There are still some hurdles to overcome, like the weight of the solar panels. ( Recommended: Waste In Space Will Be Fetched By The Cubesail carbage Truck ) It will also cost billions of dollars to make these solar farms in space happen. The research, the tests and the solar satellites itself (price tag: about ten billion each) will make this a very expensive project – to say the least.

Solar Energy Turned Into Liquid Fuel Can Be Stored 18 Years
It works like a rechargeable battery, which is charged by the sun.  A major discovery in the field of solar fuel could make it possible to store solar energy for years to come. It is hard to believe that we are still using fossil fuels that contribute to climate change. We have a sun bombing our planet daily with abundant, clean, renewable energy. However, fossil fuels do have an often overlooked advantage over solar energy, which has long prevented solar energy from really popping up: they are fuel. Sunlight in a bottle? Solar energy, for all its benefits, does not come in the form of fuel, which essentially means it cannot be stored easily. This could now all change, following a breakthrough in the development of a fuel that can capture and save the sun's energy. Scientists say that this fuel can store that energy for up to 18 years, reports NBC. Call it 'sunlight in a bottle'. Researchers in Sweden have detected a specialised liquid that operates like a rechargeable battery. The sunlight shines on the device, and the fluid absorbs it. At a later stage, that energy can be released as heat by merely adding a catalyst. This remarkable discovery could be how we power our homes by 2030. How to get sunlight in and heat out? "A  solar thermal fuel is like a rechargeable battery, but instead of electricity, you put sunlight in and get heat out, triggered on demand," explained Jeffrey Grossman, who is in charge of the MIT lab working on the project.  It is incredibly easy. The liquid consists of a molecule of carbon, hydrogen and nitrogen that reacts to the presence of sunlight by shifting its atomic bonds. The particle, fundamentally, transforms the molecule into a cage that "captures" the energy of the sun. Surprisingly enough, this energy content is retained even after the liquid itself has cooled to room temperature. To release the energy, pass the liquid over a cobalt-containing catalyst, returning the molecules to their original form. As a result: energy from sunlight comes from the cage as heat. "And when we come to extract the energy and use it, we get a warmth increase which is greater than we dared to hope for," says Kasper Moth-Poulsen, one of the team members. A rechargeable device that does not lose capacity Early results have shown that once the liquid has passed by the catalyst, it heats up with 113 degrees Fahrenheit. But researchers believe that with the right mixes they can elevate the output to 230 degrees Fahrenheit or more. Noted today, the system can double the power capacity of Tesla's reputed Powerwall batteries. This has drawn the attention of countless investors.  Even better, researchers have tested the liquid through as many as 125 cycles. The particle has shown almost no degradation. In short, it is a rechargeable battery that continues to take charge without losing much capacity over many applications. What is it being used for? The technology is intended to be applied for domestic heating systems, like powering a building's water heater, dishwasher, dryer, etc. Since the energy comes in the form of fuel, it can be stored and used even when the sun is not shining. It should also be possible to  transport energy through pipes or trucks.  If everything goes as planned - and it seems to be going much better than expected so far - researchers estimate that the technology could be available for commercial use within ten years. Given the rapidly escalating climate change crisis, this could not happen fast enough. https://www.whatsorb.com/category/energy

Solar And Battery-Based Generator: Electricity Anywhere
If you are looking to generate energy in a mobile or off-grid place, this most likely requires a petrol generator. These polluting generators are used pretty much on a daily basis by building companies, farmers, and festivals. And while it certainly does not help the environment, it is the only option, for now. Environmentally friendly Needless to say, they are far from environmentally friendly. It is mostly based on the decade-old car technology. Back then, there were no strict regulations regarding emissions. This allowed car manufacturers and other users of petrol generators to pollute freely. While they are decidedly not ‘green’, there is an added downside, as they are generally very noisy and user-unfriendly as well. This is not to mention the huge amount of fuel that it consumes. Now, Volta Energy has created an alternative! The Volta Naos is a solar and battery-based system that can power the same devices or machinery as used by builders, farmers, and festival organizers alike - all while not using any fuel. This makes the system more sustainable. On top of that, it is silent and more user-friendly. Oh, did we mention that it is also a lot cheaper to operate? The Volta Naos is a modular system. This means that it can be extended or reduced through clicking on an extra battery and solar module . The latter uses a sun tracking system to maximize yield, which is a great way of using renewable energy sources effectively. And no, this system is not massive and top-heavy either. Even better, it can be transported using a van or a trailer. Additionally, the system as a whole can be lifted by a person (in line with relevant ARBO legislation). All of this makes it the ideal successor of the old-fashioned generators. Volta Energy has just successfully finished its prototyping phase and is scaling up its production of Naos systems. The first customer, that effectively launched it, was a city in the direct vicinity of the company’s base. This summer, several systems were rented out to users who had previously only used petrol generators, which led to great and valuable feedback. For the next year, Volta Energy is looking to 'green up' as many festivals as possible. They aim to do so by matching the price of the system with the price of a petrol generator. As such, cost can no longer be the reason for not opting for the more sustainable solution. Currently, the rental website is under construction to fit it to this purpose, while more rental systems are set up and a renting corporation is put in place. All to be ready for what is to come! Interested in the company? Or are you interesting in renting the Volta Naos for the weekend? Find out more at www.volta-energy.com .  https://www.whatsorb.com/category/energy
