Kyocera’s solar-powered smartphone prototype

Kyocera has developed a smartphone prototype that features a display with a Wysips Crystal layer for harnessing solar power

Kyocera is showing a new solar-powered prototype that can also charge anywhere, so long as it’s not too dark or cloudy.

This week at Mobile World Congress in Barcelona, Kyocera is showing off a concept phone that uses its own display to convert the sun’s rays into juice for its battery. While we’ve previously seen devices that harness the sun’s rays via solar cells mounted on the chassis, Kyocera’s prototype employs a transparent photovoltaic layer that can be placed on top of or beneath the touchscreen.

According to Gizmag, the specific technology on display this week comes from a company named Sunpartner, which makes a power-generating display layer called the Wysips (What you see is photovoltaic surface) Crystal connected to a chip that manages and converts solar energy into power that can be stored in the device’s battery.

Sunpartner says Wysips is capable of delivering up to 5 milliWatt-peak/cm2, a figure the company expects to soon double thanks to next-generation photovoltaic materials. The layer is only 0.1 mm thick, making it easy to add to a device without impacting the aesthetic design. The company also claims that it will not impact the the display’s touch capabilities.

While today’s high-powered smartphones won’t likely be able to be self-sufficient on solar power alone, lower power devices like e-readers and more basic phones could theoretically go charger free with this kind of technology. A Tag Heuer watch sporting one of these layers is touted as having “infinite power.”

In the instance of smartphones like Kyocera’s, Sunpartner says its technology could offer infinite standby time so long as sunlight is available. Perhaps the best selling point for those who use ruggedized phones in the field is that the solar power layer can essentially offset the battery drain caused by searching for a network in more remote areas and allow for a reserve of power for emergency calls.

While Kyocera seems to be the first company we’ve heard of demonstrating solar power generated from a device’s screen, Sharp did something very similar several years ago with a solar “lid” for a smartphone, but that never really made it to any markets beyond Asia.

Sunpartner, on the other hand, says its system can work on displays ranging from three to 13 inches, including smartwatches, phones and tablets. For more on the technology, check out the promotional video below.

Samsung gives a Solar Powered Internet School to learners in Mpumalanga

Solar Powered Internet School

Samsung’s Solar Powered Internet School

Samsung Electronics South Africa has delivered a Solar Powered Internet School (SPIS) to the Chief SW Nhlapho Secondary School in Dundonald, Mpumalanga. The executive mayor of Chief Albert Luthuli Municipality, B.P. Shiba, attended the handover ceremony, along with the Department of Education’s acting district director, P.P. Magagula.

Head of Corporate Citizenship at Samsung Electronics South Africa, Pitso Kekana was also in attendance.
Many communities facing economic and geographic challenges often have little or no access to electricity and Samsung designed the SPIS with these issues in mind.

According to Media Update, the units come completely self-contained with solar generators and wireless communication, providing unlimited access to technology, communication and information as long as there is sunlight to power the solar panels, digital cellular network or satellite connectivity.

This initiative is part of Samsung’s Corporate Citizenship programme, which seeks to provide educational material and connected classrooms to disadvantaged communities.

Chief SW Nhlapo Secondary School was established in 1994 and currently has 643 learners. In 2014 the school obtained an 81.03% pass rate, producing the highest number of matric passes in Dundonald.

The pupils of this school possess an incredible amount of dedication and perseverance and the school is geared towards advancing the surrounding community. The secondary school was crowned as the proud winners of a national competition called the ‘2012 Youth Citizens Action Programme’, where learners were challenged to demonstrate empowered active citizenship.

The Chief SW Nhlapo High School presented a road safety campaign which tackled a number of challenges they faced outside their school. The campaign generated awareness for learners to make use of the pedestrian crossings and have the boundaries of their roads fixed.

In addition, the learners approached local traffic police to assist with taking non-roadworthy vehicles off the road, which is one of the main contributing factors to road accidents. This school demonstrated that hard work and persistence is a reward on its own.

“The school’s drive and enthusiasm displayed in their zeal to make the road safety campaign a collective achievement, further gives us faith that they will indeed make a success of the SPIS,” concludes Kekana.

Historic low price on wind power in Denmark

cheap wind energy in Denmark

Cheap wind energy for Denmark

A massive new offshore wind farm off the west coast of Jutland will provide power at nearly one third the price of existing wind parks, the Danish Climate Ministry announced Friday.

According to The local DK, a new offshore Danish wind farm, Horns Rev 3, will be built by the Swedish state-owned company Vattenfall. The Swedes guaranteed a price of 10.31 euro cents per kilowatt hour, which the Climate Ministry said will save Danish consumers around 2.2 billion kroner (295 million euros) over the next 12 years.

The ministry said that although direct comparisons are difficult, the Horns Rev 3 project is likely to be the cheapest wind farm in Europe and one of the cheapest in the world.

“With Horns Rev 3, Denmark is making windmill history through realizing a significant reduction in the cost of establishing offshore wind farms. There is no doubt that the power from offshore wind turbines will continue to be an essential part of the green transition and contribute effectively to reducing CO2 in the atmosphere,” Climate Minister Rasmus Helveg Petersen said in a statement.

The ministry said that Horns Rev 3 will produce wind power at nearly one third the price of the most recent Danish offshore wind farm, the Anholt Offshore Wind Farm located in the Kattegat.

The Horns Rev 3 project will receive state subsidies until the wind park has produced a determined amount of energy. Although the Climate Ministry’s press release didn’t include a specific figure, Petersen said that the subsidies would like last 11-12 years, after which point the windmills will produce electricity at the market price.

Denmark is a global leader in wind energy. In 2014, the nation set a record by producing 39 percent of all electricity through wind power. By 2020, the Danish government plans to have half of all electricity produced by wind power.

But for wind power to truly take off internationally, energy experts say that costs need to come down significantly. Petersen said the Horns Rev 3 deal could help set a precedent for cheaper wind power.

“The low price is not just good for Denmark, but also for the international green transition. The general decline in prices in the market for wind power means that offshore wind power is now well on its way to becoming a viable competitive alternative to traditional fossil fuels,” he said.

Solar energy powers innovation at Cook Medical

one of the largest PERC solar installations

Cook Medical to build one of the largest PERC solar installations

Cook Medical partnered with Positronic Solar and WINAICO to build one of the largest PERC solar installations in Asia Pacific – 99.90kW

According to a press release, world leading medical device manufacturer, Cook Medical, has taken one giant leap to reduce its carbon footprint and power bill, by installing a 706 square metre field of solar panels on its roof in Brisbane. The installation is the largest of its kind in Asia Pacific, utilising advanced solar panel technology called PERC (passivated emitter- rear contact).

“We have a roof and lots of sun, so harnessing solar power was an obvious solution to reduce costs for us and the environment. The investment was significant, but even so we expect our solar panels will pay for themselves within 15 years,” Barry Thomas, Cook Medical Vice President and Managing Director of Cook Medical Australia said. “Using alternative energy to power manufacturing still isn’t mainstream, but given the benefits it’s completely logical. We’ve chosen an extremely efficient technology, and the panels are now offsetting on average 30 per cent of the power we use each day.”

The installation of the panels was finished in January, and was carried out by local company, Positronic Solar, who recommended and installed the custom-design. John Inglis, Director of Positronic Solar was impressed by Cook Medical’s commitment to alternative energy. “When we put in our proposal we were very honest about what was achievable and the best technology for Cook Medical’s solar panels. They appreciated our straightforward approach, and chose an effective solution to offset a significant majority of their power use,” said Mr Inglis. “The design utilises Schneider-Electric inverters and WINAICO high efficiency PERC 280 W monocrystalline modules – some of the most advanced technology available. The panels are not only efficient even in low light, but also perform very well at high temperatures – which is of course very important here in Queensland.”

Cook Medical

Cook Medical Australia was established in 1979 and has grown to a headcount of over 500 people at their headquarters in Eight Mile Plains where its headquarters are based.

Founded in 1963, Cook Medical pioneered many of the medical devices now commonly used to perform minimally invasive medical procedures throughout the body. Today, the company integrates medical devices, drugs and biologic grafts to enhance patient safety and improve clinical outcomes. Since its inception, Cook has operated as a family-held private corporation.

Cheap solar cells made from shrimp shells

Solar cells from shrimp shells

Solar cells from shrimp shells

Scientists from Queen Mary University of London (QMUL) have created electricity-generating solar cells using chemicals derived from the shells of shrimp and other crustaceans, a development that could have a major impact on the cost of producing solar panels.

According to Energy Matters, the research is focused on nanotechnology, specifically the highly conductive light-absorbing quantum dots used in thin-film and spray-on solar technology.

These tiny crystals can be tuned to specific wavelengths of light, multiplying the energy production of electrons throughout solar devices. They can also trap and convert infrared light to energy, light that would otherwise heat up and degrade photovoltaic processes.

The team discovered that two materials found in the shells of shrimp and crustaceans, chitin and chitosan, could be used to replace expensive metals like ruthenium and platinum, the expensive and rare metals used to make carbon quantum dots (CQDs).

Using a process known as hydrothermal carbonisation, the QMUL scientists incorporated the shrimp-derived chemicals to successfully produce CQDs. They then coated zinc oxide nanorods with the quantum dots to make solar cells.

“This could be a great new way to make these versatile, quick and easy to produce solar cells from readily available, sustainable materials,” said Dr Joe Biscoe, a researcher on the project.

The efficiency of the solar cells is low compared to the silicon-based solar panels used in rooftop PV systems, but the team hopes their discovery of an organic replacement for rare-earth materials in the production of CQDs will result in cheaper solar energy, at least in the field of thin-film technology.

“Once we’ve improved their efficiency they could be used anywhere that solar cells are used now, particularly to charge the kinds of devices people carry with them every day,” Dr Briscoe said.

Professor Magdalena Titirici, Professor of Sustainable Materials Technology at QMUL, added,

“New techniques mean that we can produce exciting new materials from organic by-products that are already easily available. Sustainable materials can be both high-tech and low-cost…We’ve also used biomass, in that case algae, to make the kinds of supercapacitors that can be used to store power in consu

Solar to become cheapest source of energy over next decade

Solar energy to become the cheapest source of energy

Solar energy is set to become the cheapest source of electricity in many parts of the world within the next 10 years, according to a new report from German think tank Agora Energiewende.

Solar energy is set to become the cheapest source of electricity in many parts of the world within the next 10 years, according to a new report released by German think tank, Agora Energiewende.

The report was commissioned by the independently funded organisation, designed to steer Germany towards its 80 per cent renewable energy target.

According to Radio Australia, chief executive officer Dr Patrick Graichen said they wanted to see if recent falls in the cost of photovoltaics would continue.

“The finding is there’s no end to the cost decline in photovoltaics,” he said.

“The technology still has further improvements so we expect that within the next 10 years photovoltaics will become, in many regions of the world, the cheapest source of electricity.”

Dr Graichen said in some sun drenched parts of the world, it would be cheaper than burning fossil fuels.

The Current and Future Cost of Photovoltaics report found the price drop is set to occur even in conservative scenarios, and assuming no major technological breakthroughs.

Dr Graichen, former head of the Division for Energy and Climate Policy at the German Federal Environment Ministry, said the falling price was being driven by several factors.

“It’s the technology itself, the modules have become cheaper because China is now producing them on a very large scale,” he said.

“So we have the effect of the mature technology with a global market, where prices decline, and second, we’ve got to know better how to integrate it into the systems during the past five-six years.”

He said it was surprising Australia had not taken up the technology to the extent of countries like Germany.

“We have in Germany an extensive program on photovoltaics in the past years, and that has led to about 40 gigawatts being installed,” he said.

“That is still only 6 per cent of our electricity production, but still it is already 6 per cent, and we’ve seen how that already impacts on our electricity system in the sense that we don’t need peak power of gas-fired power plants in the summer anymore.”

He said given Australia’s sunny climate, solar energy should be thriving.

“If you look at that technology and you ask yourself the question, ‘where in the future will we have cheap and clean energy?’ It’ll be those countries in the world with a lot of sun and with stable investment conditions,” Dr Graichen said.

“You see a lot of solar projects are now coming up in the Gulf, in New Mexico, California, Texas, but Australia is lacking in that concept.”

The study highlighted while the cost of producing hardware for solar will continue to decline irrespective of local conditions, the financial and regulatory environments will be key to ongoing price falls.

It said stable regulatory conditions are needed to keep the cost of finance down.

Dr Graichen said the world needs the cheap and clean energy solar power can provide.

“Obviously this is a threat to all those that are betting on coal, but there has always been structural changes, major structural changes to economies,” he said.

“Those that were building railroads weren’t happy about cars either, but in the end the cars came because the technology was better suited to the needs of the 20th century.”

SunEdison to build 15 GW renewable energy capacity addition in India

SunEdisin plant in India

New energy capacity addition for SunEdison in India

SunEdison has announced that it will set up 15.2 GW of solar and wind energy capacity in India over the next 5 years. The company is expected to develop solar as well as wind energy projects.

This would be SunEdison’s contribution to India’s ambitious target to add 100 GW renewable capacity by 2022. India’s installed renewable energy capacity currently stands at just above 32 GW.

According to Clean Technica, SunEdison had recently signed agreements with the state governments of Rajasthan and Karnataka to set up large-scale renewable energy projects. In Rajasthan, the company will add 5 GW solar power capacity while in Karnataka the company will add an equal capacity but through solar and wind power technologies.

SunEdison has been taking part in solar power project auctions conducted in the past by several state governments and the central government.

In addition to utility-scale power projects the company will also set up significant distributed renewable energy capacity. The company recently announced an agreement with a local firm to set up 250 MW distributed solar photovoltaic power projects in around 5,000 villages.

SunEdison also commissioned India’s first canal-top solar PV project in Gujarat.

Last month SunEdison signed an agreement with Adani Enterprises to set up India’s largest solar PV modules manufacturing unit in Gujarat. The project is expected to require a total investment of $4 billion.

SunEdison made this ambitious commitment at RE-INVEST, an investor summit organised by the Indian government. First Solar committed to set up 5 GW solar power capacity at the same summit. This brings to total commitment to over 20 GW over the next 5 years from these 2 American companies.

In comparison, when the Indian government launched the National Solar Mission in 2010 it had set a target to add 22 GW of solar power capacity by 2022.

Meet the vanadium-flow battery with 250kW of liquid energy storage

flow battery

Vanadium-flow battery

Imergy Power Systems developed a new, mega-sized version of their vanadium flow battery technology. The EPS250 series can deliver up to 250kW of power with a 1MWh capacity.

According to Extreme Tech, a flow battery can be thought of as a type of rechargeable fuel cell. The electrolyte fuel, in this case, is kept in large external tanks that can be pumped through a reactor.

One of the characteristics of a flow battery is that the energy storage can be decoupled from the energy output. The size of the reactor determines how much power can be released at once, while the size of the storage tanks determines how much total power can be stored.

This, in turn, makes it theoretically much easier to expand the size of a flow battery installation as compared to a lithium-ion battery. Doubling your battery life is theoretically as simple as doubling the size of the storage tank. Flow batteries can charge and discharge rapidly — refilling the tank with “charged” electrolyte can be as simple as opening a nozzle and pumping in the replacement fluid while the original electrolyte is recharged in a separate container.

There are different types of flow batteries and multiple compatible battery chemistries, but Imergy’s designs all use vanadium for both electroactive elements.

The ability to fill both ‘sides’ of the equation is an unusual property of vanadium and it simplifies certain aspects of the reactor design. Vanadium flow batteries are extremely stable — leaving the battery in a discharged state causes no damage, and the battery has an estimated lifespan of 30-50 years and supports thousands to tens of thousands of discharge cycles — far more than lithium-ion can manage.

The disadvantage of flow batteries is that the total energy density of the solution is rather low energy density and the complexity of the storage and pumping mechanisms. Research into improving vanadium’s energy density is underway, a team at the Pacific Northwest National Laboratory has found a way to boost the energy density of vanadium batteries by up to 70% by switching to a different electrolyte formulation.

The long-term market

Much of the debate over the long-term usefulness of battery technology in the US centers around whether or not batteries can be combined with solar and wind power while still matching the cost of existing natural gas, coal, and nuclear plants.

What’s often ignored is that these equations look very different in other parts of the world, particularly in Africa or Indonesia where import costs are high, infrastructure limited (or nonexistent) and natural deposits of fossil fuels are low.

Africa also has enormous renewable energy potential — it receives huge amounts of solar power, its hydropower generating capability is largely untapped, and its geothermal and wave power are both abundant. The East African Rift in particular has high potential as a long-term geothermal power source.

Vanadium flow batteries could potentially augment renewable power in many areas across the continent, and Imergy is focusing its efforts on both the developing and the developed world.

The company claims it can deliver power for a levelized cost as low as $300 per kWh, which would put it in competition with lithium-ion costs — including, possibly, in competition with Tesla as that company scales up its own industrial battery efforts.

Community wind farm rises near Ithaca

wind farm

Community wind farm

For the past eight years, Marguerite Wells, an organic flower farmer, has quietly raised more than $1 million to build seven wind turbines on a hillside outside of Ithaca. During that time, she’s also had a lot of kitchen table discussions with neighbors worried about 475-foot turbines spinning in their backyards.

“This is a way we’re getting it done without any changes in legisation,” the 37-year-old Enfield resident said. “It’s just regular people doing something they want to happen. It’s just democracy by dollars.”

Large renewable projects often take years of planning, but Wells’ project in Tompkins County is unique because she has no energy industry background and has undertaken a major project large companies and investment groups take years to bring to fruition. She’s doing it, she says, to show that renewable energy projects are feasible, a good investment and important for the future of the energy grid.

According to Capital New York, Wells has already received many of the key state and local approvals a large project requires and expects the first holes for the turbines to be dug this summer. If completed, the Black Oak Wind Farm in the town of Enfield, about 20 miles west of Ithaca, will be the first community-owned wind farm in New York. And while its construction is still not guaranteed, landowners have agreed to site the wind turbines on their property.

At the same time, Black Oak has received the backing of the state as well as a major community institution.

Cornell University has agreed to purchase all of the power produced by the project. The New York State Energy Research and Development Authority will support the project for a decade by purchasing renewable energy credits.

NYSERDA will work to encourage more community projects like Black Oak, said Doreen Harris, senior project manager.

“We see this as a model for considering in terms of its replicability for New York,” she said. “NYSERDA sees a large role for communities and involvement in reaching the state’s targets.”

Wells said there were so few projects like hers, she had to travel to South Dakota to find another community-owned wind farm to copy. Now that she is so close to breaking ground, she said she expects this project won’t be the last time private citizens organize their own utility-scale renewable projects. They can use her ideas, and fit them around the unique needs of their community projects, she said.

Black Oak is relatively small. At 12 megawatts, it would provide enough power for about 5,000 homes. The site in Enfield has average wind speeds of 17 m.p.h., better for generating electricity than other state wind farms that have average wind speeds of 14 m.p.h.

The project will cost about $40 million to complete. Wells has raised at least $1 million, much of it from private citizens, including a number who lives near the farm. She said she recruited more than 100 like-minded investors in initial rounds of funding, including those who support clean energy and view it as a chance to make money. The bulk of the funding, she said, will come from banks and private equity firms who see the project as economically viable.

The project has been delayed a few times and has been cut in size from 20 megawatts to the current configuration. And while there is no guarantee Wells will get the money she needs in time to begin construction in just a few months, she said she is close to final deals with three major financial backers. She is also working on a payment in lieu of taxes, or PILOT, agreement with the Ithaca city school district, the town of Enfield and the Odessa Montour Central School District.

For Cornell, the project allows the school to move closer to a goal of zero carbon emissions by 2035.

“As we use more wind, we reduce our dependence on carbon-produced electricity,” KyuJung Whang, Cornell vice president for facilities services, said in a statement. “This is a major step toward Cornell becoming a carbon neutral campus.”

After announcing a fracking ban in December, Governor Andrew Cuomo said some of the areas that would have benefited from natural gas drilling could now receive clean energy projects. Environmental groups that have spent years mostly focused on fracking said they would turn their attention toward promoting renewable energy. Those efforts have yet to be rolled out.

Wells is ahead of both, though the state signed on to support her project in 2013 because it was economically competitive. Environmental groups have been slow to realize its promise, but Wells is traveling to Albany soon to meet with them to encourage more outreach to their members on investments in community renewables.

The project is also an example of what the state needs most to grow its renewable energy portfolio, private capital invested in major initiatives that can succeed in an open market without major subsidies. After years of stagnant growth, Cuomo has launched billions of dollars in clean energy initiatives, most with the aim of aligning solar, wind and other renewable sources with the market, so that they can exist without subsidies. The state’s Reforming Energy Vision initiative, which is being watched nationally, is designed to make the state energy markets more accomodating to renewable projects.

It’s also the type of clean energy resource, a utility-scale project, that the grid needs if it is to reduce carbon emissions 80 percent by 2050, as Cuomo has pledged. Wind projects have increased more than any other renewable energy under Cuomo, by about 600 megawatts to a total of 1,875 megawatts since 2010. Still, the state got just 23 percent of its power from renewables in 2014, far short of former governor George Pataki’s plan to get 30 percent of the state’s power from renewables by the end of this year.

Wells said it has helped that her project is near liberal Ithaca, a place where people appreciate renewable energy, she said. That made the tough sell of convincing people to have turbines as tall as a skyscraper spinning in their backyards.

“Ithacans take green energy so seriously, they know they can’t say ‘not in my county, in someone else’s county,’” she said.

Thus far, the project has received little support from the state’s most prominent environmental groups, Wells said, despite years of pitches.

Wells said getting popular public support, and showing people the investment power of renewable projects, is her next push. She has a meeting with green groups in Albany later this month, to get them on board with the project and to convince them to encourage their members to invest in the future of the energy grid.

“They haven’t seen anything like me and don’t know how to support me,” she said.
