World's first smog filtering tower goes on tour

The Dutch city of Rotterdam has opened the world’s first smog-free tower.


Co-designed by Dutch artist Daan Roosegaarde, the seven-metre high tower sucks in dirty air like a giant vacuum cleaner. Ion technology then filters it, before returning bubbles of smog-free air through the tower’s vents. It is able to clean 30,000 cubic metres of air an hour, according to Roosegaarde.


Clean air is a precious commodity. A new study has found that more than three million people die prematurely due to air pollution each year. This is projected to double by 2050 if the problem isn’t tackled.


“The smog-free tower contributes to a debate that shouldn’t be confined to politics,” says Rotterdam’s mayor, Ahmed Aboutaleb. “Air pollution is a matter that affects us all, and it requires a serious discussion. But we do need innovators like Daan Roosegaarde to start the conversation at another level.”


Roosegaarde has far-reaching ambitions for the tower, which is part of his Smog-Free Project. “It’s not only intended to be a local solution that creates clean parks or playgrounds,” he explains. “It’s also a sensory experience of a clean future, a place where people can experience clean air.”


He hopes to bring together governments, NGOs, the clean tech industry and ordinary citizens. “We can work together to make whole cities smog-free,” he says. “We can wait – or we can participate.”


The man behind the tower’s Hoover-like cleaning filter is Bob Ursem, a nanoparticles expert at the Delft University of Technology. In outdoor tests, the filter has cleaned the air by 60%, measured by the share of nanoparticles removed, and in indoor environments the reduction is even more significant, he claims. “We’ve installed it in a parking garage here in the Netherlands and it sucks and cleans both the inside and outside air,” Ursem says. “Inside the parking garage, the air became 70% cleaner.”

But it’s not Rotterdam where the need for air filters is greatest. According to the World Air Quality Index, most of western Europe enjoys clean air, with exceptions including London, where air quality is classified as moderate. It’s a different story in the booming cities of the developing world and the Bric countries. Air quality is much poorer in China and Malaysia, for example, where most cities feature air deemed unhealthy for sensitive groups. The air in several cities, including Delhi, has been classified as very unhealthy, indicating emergency conditions.


The tower’s creators recognise this and, after its run in Rotterdam, the tower moves to Beijing, a city suffering from very poor air quality.


Earlier this month, Chinese authorities shut hundreds of factories in Beijing and banned half of the country’s 5m cars from the roads in preparation for a gigantic military parade. In the days leading up to the parade, the air quality improved, resulting in pristine blue skies for the parade, only to return to smog when the ban was lifted.


According to Ursem, Rotterdam’s filter can easily be scaled to help alleviate Beijing’s smog. Yet while smog filters may offer some hope to suffering residents of booming cities, as the military parade ban suggests, no one technology or tactic can be as effective as working on the root causes of air pollution. In the tower’s case, the filters would be costly too . While neither Roosegaarde nor Ursem would disclose the cost of the tower, the filters they have developed range in price from €1,600 to more than €118,000.


Aboutaleb acknowledges the innovation’s limitations: “It may not be the answer to all our problems, but this shouldn’t be the main objective,” he says. “The objective must lie in a different perspective, a refreshing approach to a global problem.”


Esben Alslund-Lanthén, a researcher at the Danish sustainability thinktank Sustainia, says the filter is not a large-scale environmental solution but can be useful as an awareness-building: “It shows how polluted our cities are, especially from energy and transportation”.


A person who has inhaled the tower’s healthy air may find it a shock to return to the more polluted city air outside the clean bubble.


“Whether the air filter is scalable or not depends not just on its technical viability, but on whether city governments are good at learning from each other to bring about change,” argues Sascha Haselmayer, founder and CEO of Citymart, a firm that connects urban innovation projects with cities.


Some local politicians seem keen to encourage clean air-thoughts among their residents, perhaps hoping that it will make them more amenable to restrictions on fuel and dirty energy. New York City, Ursem reports, has just ordered 12 street-cleaning cars featuring the air filter. There will be a pilot air-filter project in Eindhoven, and Ursem’s team is in negotiations for a similar project in Paris.

Chipmaker installs wind turbines to power its headquarters in Silicon Valley.


Intel has deployed 58 JLM Energy’s Zefr micro-turbines on the roof of its Santa Clara, US, headquarters.


On top of generating power for its building, Intel will use the project to understand the feasibility of small-scale wind application for power generation and how to optimise future installations.


The company added that it will share the data extracted from the turbines with local companies to enhance green energy adoption across the region.


The six to seven ft tall turbines, installed at the Robert Noyce Building, are expected to generate power 65% of the time, “most likely during the often-breezy afternoon hours”.


Brian Krzanich, Intel’s CEO said: “Intel is proud of this [micro-turbine project]. We want people to see this, and to know that we’re thinking about new ways to do things.”


Since 2008, Intel has invested $118 million in energy conservation and completed over 2,300 projects.


The company added that these investments generated cumulative energy cost savings of $249 million through the end of 2014.

Pakistan's Parliament House Goes Solar with Yingli Green Energy









BAODING, China, April 23, 2015 /PRNewswire/ — Yingli Green Energy Holding Company Limited (NYSE: YGE) (“Yingli Green Energy” or the “Company”), one of the world’s leading solar panel manufacturers, known as “Yingli Solar,” today announced that Pakistan’s Parliament House will be powered by 1 megawatt (MW) of high efficiency multicrystalline Yingli Solar panels. The project was fully funded by the Chinese government, and was inaugurated by the leaders of China and Pakistan on Tuesday, April 21, 2015.


The Yingli Solar system is expected to generate approximately 1.6 million kilowatt-hours of solar electricity annually, offsetting approximately 2,500 tons of carbon dioxide emissions. It is anticipated that the system will be completed by the end of June 2015, and that it will reduce the building’s electricity costs by up to Rs28 million (USD27 thousand) per annum. China Railway 17th Bureau Group Co., Ltd. is in charge of the engineering, procurement and construction of the project and the Company will supply its YGE 60 Cell Series panels for the project.


“We are delighted to make this breakthrough in Pakistan’s emerging solar market and help Pakistan’s Parliament House to go green alongside our partners,” commented Mr. Liansheng Miao, Chairman and Chief Executive Officer of Yingli Green Energy. “It is an honor to contribute to these two countries’ efforts to strengthen their relationship, and this project is sure to help Yingli solidify its reputation and intensify its development in the market.” 


With abundant solar radiation resources and a severe electricity shortage, there is huge potential for solar energy in Pakistan, where the energy mix is currently dominated by oil and gas. Pakistan’s government introduced a feed-in-tariff (FiT) scheme at the beginning of 2014, which applied to solar power plants of between 1 MW and 100 MW capacity with varying rates in the north and south of the country. The government also approved a net energy metering system, which allows solar panel purchasers to sell the power they produce to the national grid, at the end of 2014.

Germany recharged: EU powerhouse goes all in on alternative energy


On a recent Saturday afternoon, a couple of engineers working the weekend shift were monitoring the regional electricity grid in the heart of Potsdam, a city south of Berlin. The control room was largely quiet as the technicians bent over their workstations, scrutinizing the flow of power through the system.



Ralf Doering, a network manager for E.dis AG, the grid operator, pointed to a screen, where an innocuous-looking red line on a chart had just dropped to zero. The line measured how much electricity the grid drew from conventional sources of energy.


As of a few minutes earlier, a swath of northeastern Germany from the Baltic Sea to the Polish border, an area roughly the size of Switzerland, was being powered entirely by energy from the wind and the sun. A group of visitors looked around the room – at the lights, the computers, the equipment – and mentally multiplied the scene across the entire region. “Solar and wind are now enough,” Mr. Doering said matter-of-factly.


If Germany continues on its current course, such moments will become commonplace. The country has embarked on the most ambitious energy revolution anywhere in the industrialized world. Last year, 26 per cent of Germany’s power supply came from renewable sources. By 2050, the figure is targeted to rise to 80 per cent. The shift, Foreign Minister Frank-Walter Steinmeier said last month, is Germany’s “man on the moon” project.


As Germany has discovered, however, a project with sky-high aims can carry a huge price tag. The initiative, which began in 2000 and is a top priority for Chancellor Angela Merkel, has pushed electricity prices for German consumers to the second-highest level in the European Union, behind Denmark. German businesses also pay some of the highest prices for power in the region, with exceptions for certain energy-intensive industries.


German business groups complain that the country’s energy policy hurts their ability to compete and plan long-term investments. They’re especially galled by Ms. Merkel’s decision, in the wake of the Fukushima disaster in 2011, to commit to closing of all of Germany’s nuclear power plants by 2022.


More recently, the energy policy – which is aimed squarely at reducing Germany’s contribution to climate change – witnessed a disturbing paradox. Between 2009 and 2013, carbon dioxide emissions from Germany’s power sector actually rose, despite the growing share of electricity produced by wind, solar, hydro and biomass. That’s because power companies were increasing their use of cheap but carbon-laden energy sources like lignite and hard coal compared to previous years. Those sources became more attractive for two reasons, experts say: the higher price of natural gas and the low cost of carbon-emissions permits in the European trading system.


Alarmed by that development and by the upward march of electricity prices, Ms. Merkel’s government introduced revised energy legislation last year that moved to rein in the surcharges for renewable energy. The government is also looking at placing new restrictions on coal producers to bring down emissions. Experts estimate that emissions in 2014 from Germany’s power sector fell to their lowest point since 2009.


Despite the hurdles, Germany is plunging full-speed ahead in what is known here as the “Energiewende,” or energy transition. But its leaders acknowledge that unless Germany can prove that the policy works for businesses too, it risks being deemed a failure.


“We need to show that in a country like Germany and a continent like Europe, it is possible to have a high level of industrialization” in combination with policies to mitigate climate change, Sigmar Gabriel, the Economy and Energy Minister, said last month. Only then, he said, “will we find that other countries follow us. Only then will we persuade people.”


Unintended consequences


In late March, policy makers from more than 50 countries gathered in Berlin for a conference to discuss the challenges of transforming a country’s energy supply. Some were from oil-rich nations such as Kuwait and Algeria; others were from smaller European nations that already generate much of their electricity from renewable sources. In Portugal, for instance, the figure is more than 60 per cent.



What Germany is attempting, however, is far more complicated. It is the world’s fourth-biggest economy, with a large industrial sector. Other major economies such as France and the United Kingdom have less lofty targets for renewable energy and aren’t phasing out nuclear power.


At the conference, Jan Mladek, the Czech Minister of Trade and Iindustry, told a story that pointed to some of the difficulties Germany faces. On a visit last year to Berlin, Mr. Mladek said, he met with federal officials who urged him to speed up the Czech Republic’s adoption of renewable energy. Then, later that same day, he met with the Premier of the state of Saxony, which borders the Czech Republic. The Premier urged Mr. Mladek not to build wind farms near the border, fearing it would destroy Saxony’s tourism industry.


The story epitomizes how each step Germany has taken toward greater use of renewables has created new and sometimes unforeseen challenges – in electricity prices, in carbon emissions and in power distribution.


In Germany, consumers paid an average of nearly 30 euro cents (41 cents) per kilowatt-hour for electricity last year. In Ontario, by contrast, the peak price is currently 14 cents; the average price for consumers in the United States is similar.


Here’s what happened to prices. To hasten the adoption of renewable energy, Germany guaranteed long-term price contracts to such producers – a technique also common elsewhere in the world. The difference between those guaranteed prices and the price of power sold on the wholesale market gets passed on to consumers.


In Germany, that difference is known as the renewable energy surcharge. The surcharge has jumped from 1 euro cent per kilowatt-hour in 2009 to more than 6 euro cents currently. The increase is due to a rapid growth in the installation of green power, which has also helped to drive the market price down.


So consumers have paid more, even as the market price for German electricity has fallen considerably, because the surcharge must fill the gap. In its reforms last year, the government moved to curb further increases in the surcharge.


Despite the rising prices, support for the government’s energy policy remains strong, said Claudia Kempfert, an energy expert at the German Institute for Economic Research in Berlin. Electricity accounts for just 3 per cent of the average household’s budget, she noted, compared to heating and transportation, which takes up 30 per cent. A poll conducted last year found that 92 per cent of Germans favoured expanding renewable energy.


Businesses are far less sanguine than consumers about shouldering the costs of the transition. Electricity prices for industrial customers have risen more than 40 per cent since 2008 and companies say the policy has begun to affect their investment decisions.


The “huge costs for promoting renewable forms of energy restrict the competitiveness of our companies,” a spokesman for the German Association of the Automotive Industry said in a statement. “In the long run, that will damage employment at home.”


BASF, a chemicals giant, has said it will focus its new investments outside Germany as a result of energy costs. Last year, SGL Carbon SE and BMW Group said they would invest an additional $200-million (U.S.) in a carbon-fibre manufacturing facility in Washington state. A driving force behind the decision: the availability of cheap power.


BASF and SGL Carbon are among the roughly 2,300 large, energy-intensive German companies that are exempted from paying the renewable energy surcharge through at least 2017. But even some of these firms assert that the energy policy isn’t working.


Heribert Hauck, director of energy affairs at Trimet Aluminium SE, a large consumer of electricity, said the shifting policy terrain is making long-term investments impossible for his firm.


What’s more, he added, the volatility of renewable energy – the sun doesn’t always shine and the wind doesn’t always blow – makes it unsuitable to meet the burden of constant industrial demand.



Germany, like other countries, has not yet solved the dilemma of how to store the electricity produced by solar power and wind energy. And it has only begun to tackle the transportation of such energy, which is primarily produced in the north of the country, to the industrial heartland in the south. One major planned transmission route from north to south – the “Stromautobahn,” or electricity highway – has faced intense protest from those living in its path.


“We can implement the Energiewende up to a certain degree,” said Mr. Hauck of Trimet. But the government must leave a “supply of conventional, reliable, competitive power plants in the system. That’s what industry needs.”


Smaller companies have complaints too. Horst Linn runs a maker of industrial furnaces in Bavaria, typical of the thousands of so-called “Mittlestand” firms that form the backbone of the German manufacturing sector.


The government’s focus on renewables is wrong-headed, Mr. Linn said. Instead, it should have focused on energy-saving technology, he asserted.


Mr. Linn estimates that his company’s electricity costs have jumped 30 per cent in the past five years and fears that more increases lie ahead as the country phases out nuclear power. Yet he’s never seriously considered operating anywhere else because of the skilled labour and quality control required in his business.


“You have no chance with the product we make to go to Bulgaria,” he said.


Fingers crossed


In the middle of March, Germany’s solar industry faced a critical test. A partial eclipse for several hours on the morning of March 20 threatened to wreak havoc on the system: Grid operators faced an unprecedented fluctuation in electricity supply as sunlight disappeared with unusual speed, only to reappear with the same unusual alacrity. (Prior to the eclipse, representatives of the solar industry had asserted everything would be fine. But “really, we were like this,” said a spokesman for the industry, holding up crossed fingers on both hands).


The industry passed the test and hailed it as proof that renewable energies were now a mature and successful part of Germany’s electricity system. As the shift to renewable energy deepens, some power producers see the writing on the wall. E.on SE, a major German utility, announced in December that it would split its businesses into two.


The first will be composed of its conventional energy assets and the second will consist of its ventures in alternative energy and distribution. Some commentators likened the move to the manoeuvre deployed by some financial institutions in the wake of the 2008 crisis: dividing healthy and troubled assets into a “good” bank and a “bad” bank.


Germany’s Greens, the political party that helped kick off the energy revolution, tend to dismiss business concerns as so much bellyaching. In recent years, Germany has notched the strongest economic performance of any major European country at the same time as it has implemented the energy transition, proponents of the policy say. Norsk Hydro ASA, a Swedish company, is increasing its aluminum production in Germany, Baerbel Hoehn, a Greens member of the Bundestag, said in a recent statement.


For the Greens, the future looks a little like Feldheim, a small village of neat brick-and-stucco houses south of Berlin. On a ridge near the village, 47 wind turbines generate enough electricity to power the community’s needs 100 times over; the rest is sold to the regional grid.


The village also generates its own heat from a heavily subsidized biogas plant. Next up: a test project to create a lithium-ion battery storage facility for the renewable energy the village produces, the largest such installation in Europe.


Of course, there’s no industry whatsoever in Feldheim. Back in the grid control room in Potsdam, the electrical engineers note that the region they oversee has very few industrial concerns, which makes it easier to incorporate alternative energies.


Meanwhile, they’re plowing ahead with the many different facets of the Energiewende. “For us as engineers, it’s really challenging and exciting,” said Bernd Westphal, a regional manager at E.dis. “We’re not getting bored here.”
