Key Equipment Finance, an affiliate of KeyCorp, announced Wednesday that it has provided funding for 16 community solar projects across Massachusetts for both community solar solutions provider Clean Energy Collective (CEC) and global energy developer ENGIE.

As part of the financing deal from Key Equipment Finance, CEC and ENGIE will own and operate the community solar projects and sell the generated energy to local utilities.

The combined 16 projects are expected to have a total generation capacity of 22.1MW, which is equivalent to fully offsetting energy for 3,700 residential homes.

Luis Gutierrez, vice president of energy finance for Key Equipment Finance’s Energy Solutions team, said: “ENGIE and CEC are industry leaders using Key Equipment Finance’s financing solutions to bring a broad expansion of community solar to customers across Massachusetts. Customized financing plays a vital role in bringing the benefits of community solar to more customers, which contributes to Key’s broader sustainability goals.”

The 16 community solar projects in Massachusetts are already constructed and interconnected — with the projects set to serve customers in the Eversource and National Grid utility territories.

These projects include systems developed in the towns of Sutton, Williamsburg, Orange, Goshen, Phillipston, Uxbridge, West Bridgewater, Kingston, North Adams, Clarksburg, and Wareham.

The 25-year lifespan of the systems will produce a solar energy output equivalent to cutting down 1 billion pounds of carbon dioxide, planting 1.5 million trees or eliminating 1.1 billion miles of driving.

Tom Sweeney, CEC’s president of renewables, said: “Key Equipment Finance’s partnership has allowed CEC to bring its RooflessSolar community solar options to more Massachusetts customers, giving them greater choice in how they meet their power needs. Funding community solar projects can be a very complicated and capital-intensive process, and we are proud to be collaborating with Key Equipment Finance and ENGIE to ‘uncomplicate’ clean energy access and sustain the growing energy movement in Massachusetts.”

A capped landfill in Brockton, Massachusetts, has become a solar energy producer. According to the local CBS affiliate WBZ-TV, the landfill, once nicknamed Mount Trashmore because of the odors it produced is now doing something positive for the environment.
A new solar power system opened on top of the old Thatcher Street landfill in late June. Officials from the city claim the energy produced from the panels is equivalent to offsetting the carbon emissions of 12,000 cars annually. The report adds, the city officials estimate more than $300,000 in revenues generated from the project annually.

India has launched its first solar-powered train, which it is hoped will save around 21,000 litres of diesel a year, as the government attempts to make the country’s vast rail network more environmentally friendly.

The new 1,600 horsepower Diesel Electrical Multiple Unit (DEMU) trains are fitted with 16 solar panels on each carriage as well as battery back-ups, UNTV News and Rescue reports.

The first train, which is pulled by a diesel-powered locomotive, has been launched on New Delhi’s suburban commuter railway system, with the routes for the rest of the new trains to be decided soon.

The 7,200kw of energy created each year by the solar panels will be used to power internal lights, fans and other electrical systems on the train coaches.

Each solar-panelled coach will reportedly offset carbon emissions by nine tonnes a year, which is expected to save around 21,000 litres of diesel.

Union railway minister Suresh Prabhu told The Hindu the trains are a “path-breaking leap” towards the goal of making India’s trains more environmentally friendly.

The department of railways is also increasing its use of alternative energy sources as part of its commitment to using cleaner fuels, he added.

The solar panels last for up to 25 years and will be inspected regularly.

“It is not an easy task to fit solar panels on the roof of train coaches that run at a speed of 80km per hour,” Sundeep Gupta, vice chairman and managing director of Jackson Engineers, which worked on the project, told Business Standard.

“Our engineering skills were put to a real test during the execution of this rooftop solar project for Indian Railways.”

Major solar power project to provide electricity at night

By Ian Johnston

A major solar power project in the Middle East will provide electricity during the night, the developers have said.

The $1bn (£770m) scheme will provide up to 200 megawatts to the grid in Dubai between 4pm and 10am, according to the news service Bloomberg.

Instead of generating electricity using photovoltaic cells, the system works by using mirrors to concentrate the sun’s energy and heat water. The heat is stored in molten salt and then used to create steam that drives a turbine.

Paddy Padmanathan, chief executive of the Saudi Arabia-based company behind the project, ACWA Power International, told the news service that this system was likely to become more popular around the world.

“I expect concentrated-solar power, within 18 months, to be head-to-head with combined-cycle gas, if not more competitive,” he said.

“The focus has been on photovoltaic and batteries, but there’s a limit on how long they can hold a charge for. We’re proving that CSP [concentrated solar power] can work through the night.”

The system can heat the molten salt to a staggering 490 degrees Celsius.

Mr Padmanathan said there were currently only two companies supplying solar CSP devices.

“The others have gone bankrupt,” he said, but he added: “I know of at least five Chinese companies that are starting to enter the market.”

ACWA has built CSP plants in Morocco and South Africa and hopes to build another in Saudi Arabia.

“Right now they’re tendering for solar PV and wind, but I think they’ll want a CSP project as well, especially when they see how cost competitive it can be,” Mr Padmanathan said.

Jenny Chase, head of solar analysis at Bloomberg New Energy Finance, said the plunging costs of photovoltaic (PV) solar panels was reducing the chance that this rival method of harnessing the sun’s energy would take off.

“This plant in Dubai is for delivery by 2021,” she said. “By then, we’re expecting solar PV and batteries to be in the same order of magnitude for cost and will be a lot more flexible than a solar thermal plant.”

Read the original article Here

On July 5, Gillian King-Cargile, director of NIU’s STEM Read program in the P-20 Center, released her new children’s book, The Toy and the Test Drive. The book is the third installment in the Stuffed Bunny Science Adventure Series published by NIU Press. It explores concepts of solar power and potential and kinetic energy in a fast-paced children’s narrative designed to engage young readers.

“If we can create fun, exciting picture books that will get kids interested in the characters and the pictures, then science is exciting for kids who don’t necessarily see themselves as scientists or engineers,” King-Cargile says. “The fiction books might spark their interest in a way that more traditional non-fiction books might not.”

The book includes an interview with Seth Darling, a Nanoscientist working at Argonne National Laboratory whose work focuses on next-generation solar energy devices and solar energy systems, among other topics. Darling was a science consultant on the book.

King-Cargile is excited to release a book that addresses solar energy right now. “In a time when green energy is under attack, it’s important to keep ideas about alternative energies alive in our education system,” she says.

The Stuffed Bunny Science Adventure Series arose as a partnership between King-Cargile and the P-20 Center’s STEM Read program. The series is designed to teach science, technology, engineering, and math concepts aligned with the Next Generation Science Standards (NGSS)..

The STEM Read website (stemread.com) provides free lesson plans, video games and other activities for each book that parents and teachers can use to further engage children in the science behind the stories. Hands-on activities, such as building a solar oven and making s’mores, bring the science of solar energy alive for children.

Jeffrey R. S. Brownson, associate professor of energy and mineral engineering at Pennsylvania State University, praises the book: “This is a fun story that provides a good introduction to the science and engineering concepts surrounding solar energy.”

King-Cargile will be presenting readings and activities for children at the following times and locations.

  • 4:30 PM on Wednesday, July 12 at the Maple Park Public Library
  • 10:00 AM on Thursday, July 13 at the Cortland Community Library
  • 10:30 AM on Monday, July 17 at the DeKalb Public Library

The readings are free and open to the public. Books will be available for purchase. Proceeds from the book sales benefit STEM Read’s programs for readers of all ages.

Solar power, shade coming to MSU parking lots

By RJ Wolcott

July 7, 2017

EAST LANSING – Among the active construction projects on Michigan State University’s campus this summer is one that will keep parked cars cool. And research labs, too.

Solar panel parking bays — covered parking capable of collecting energy from the sun — are going up on five parking lots along the southern portion of campus.

Standing more than 14 feet tall at their lowest point and collectively spanning more than 700,000 square feet, the bays will collect between 10 and 11 megawatts of power during peak hours, according to Wolfgang Bauer, a professor of physics and senior consultant with the Office of the Executive Vice President.

“It’ll be the largest non-utility solar array in the state,” he said, adding that MSU’s array will provide an example to other institutions of what can be done.

Around noon on a sunny summer day, the array is expected to generate about one-sixth of the campus’ total energy needs. Annually, it’s expected to save MSU from having to generate or purchase around 15,000-megawatt hours of electricity, between five and six percent of energy consumption on campus.

“It’s a big chunk,” Bauer said, standing in the shadow of the first series of panels built on lot 89 at the corner of Farm Lane and Mt. Hope Road.

The bays are built tall to allow RVs and other vehicles driven by tailgaters on football Saturdays to park under them with ease.

The number of parking spaces in each lot isn’t expected to change as a result of the project, and parking fees won’t be impacted, Katie Gervasi, a spokesperson for MSU’s Infrastructure Planning and Facilities Office, said.

The parking bays at lot 89 will be ready for motorists by the start of the fall semester, with the other four lots coming online before the end of the year.

The array will consist of more than 40,000 individual solar panels measuring 6 feet wide by 3 feet tall.

Once operational, the solar panel parking bays will generate roughly 200 times more electricity than what’s created by the few hundred panels located on the main campus, Bauer said. Generating solar power instead of purchasing it off the grid could save MSU as much as $10 million over the next 25 years.

The parking bays are being built by Inovateus Solar, which will own the structures and sell all of the power collected to MSU at a fixed rate during the 25-year agreement. The panels are capable of turning 17% of the solar power collected into usable electricity, Bauer said, in line with the most advanced panels available today.

It’ll be Inovateus’ largest carport project once completed, said John Gulanick, a field installation supervisor with the South Bend company.

Each section is being anchored to the ground by a steel rod plunging 28 feet into the earth encased in concrete to ensure the bays can’t blow away. The panels can withstand hail and generate a small amount of heat, causing any snow to slide off.

 

Colby’s 5,300-Panel Solar Field Ready to Generate Power – and Academic Opportunity

Colby will flip the switch on a nine-acre solar field this fall, the latest step in the College’s commitment to sustainable and climate-friendly practices. The new 1.9-megawatt photovoltaic energy project, announced last May, will supply about 16 percent of the College’s electricity.

Colby declared carbon neutrality in 2013 and continues to work to reduce carbon emissions.

“Colby takes a holistic approach,” said Mina Amundsen, assistant vice president for facilities and campus planning. “We are always looking for the next way to promote sustainable practices.”

The project, undertaken in collaboration with NRG Energy, Inc., is located less than one mile from campus on a large, easily accessible, south-facing space to maximize the project’s capacity for power production. Approximately 5,300 solar panels will be installed to produce 2.5 million kilowatt hours of electricity per year.

This solar array is the latest in a series of sustainable energy projects implemented by the College. Colby already has a photovoltaic energy system on the roof of the Schair-Swenson-Watson Alumni Center that generates around 10 percent of its electricity from a steam plant on campus.

The biomass plant, booted up in 2012, saves a million gallons of oil annually by burning locally sourced forestry scraps to produce heat. Additionally, 15 of Colby’s spaces are LEED certified, and Colby is committed to seeking LEED certification—which indicates commitment to human and environmental health in its design and construction—on all new building projects.

Amundsen said Colby’s commitment to the environment includes not only sustainable energy, but also sustainable water, materials, waste, and consumption. Colby was only the fourth college or university in the country to become carbon neutral when it reached that milestone about two years ahead of schedule.

For more than a decade, Colby students have intensively studied environmental practices on campus and participated in sustainability projects; the campus’ first greenhouse gas inventory became an honors thesis in 2007.

The solar array provides another valuable learning opportunity for students, who will be able to study the system itself and the environment around it.

The cutest solar farm ever is now live on the grid

Who knew clean energy could be this cute?

China connected a panda-shaped solar power plant to the grid last week.

The project was built by the aptly-named Panda Green Energy, and has an output of 50MW, enough to power more than 8,000 U.S. households, according to Inhabitat.

It’s located in Datong, a city in the province of Shanxi, northern China.

Another panda is in the works on the site.

Two types of solar panels — white thin film photovoltaic (PV) cells and black monocrystalline silicon PV cells — give the plant the look of China’s favourite monochromatic animal.

It’s hoped that when the plant is complete, it will have an output of 100MW, and output 3.2 billion kWh of solar energy in 25 years.

The power plant is part of a UN Development Program (UNDP) effort to promote clean energy to China’s youth, and aims to teach young people about sustainable energy. It will host a summer camp organised by the UNDP and Panda Green Energy in August, for teenagers aged 13-17.

The UNDP is also organising open design challenges with Panda Green Energy.

“Designing the plant in the shape of a panda could inspire young people and get them interested in the applications of solar power,” Panda Green Energy’s CEO, Li Yuan, told state-owned Xinhua in May last year.

Panda Green Energy is hoping to build panda-shaped power plants in other countries in central and Southeast Asia, too.

The company is planning to expand into countries like Fiji and the Philippines, and wants to build over 100 panda-shaped plants in the next five years. The plants will include motifs inspired by local animals, like the koala or rhinoceros.

“I believe that the panda solar power plants will become a tourist hotspot, and in future we’ll export these panda power plants to other parts of the world,” Li told Xinhua.

Exciting new material uses solar energy to remove man-made dye pollutants from water

By Phys.org

A novel composite material has been developed by scientists in the Energy Safety Research Institute (ESRI) at Swansea University which shows promise as a catalyst for the degradation of environmentally-harmful synthetic dye pollutants, which are released at a rate of nearly 300,000 tonnes a year into the world’s water.

This novel, non-hazardous photocatalytic material effectively removes dye pollutants from water, adsorbing more than 90 % of the dye and enhancing the rate of dye breakdown by almost ten times using visible light.

The researchers, led by Dr. Charles W. Dunnill and Dr. Daniel Jones at the Energy Safety Research Institute in Swansea University, reported their discovery in the Nature open access journal Scientific Reports.

By heating the reaction mixture at high pressures inside a sealed container, the composite is synthesized by growing ultra-thin “nanowires” of tungsten oxide on the surface of tiny particles of tantalum nitride. As a result of the incredibly small size of the two material components – both the tantalum nitride and tungsten oxide are typically less than 40 billionths of a metre in diameter – the composite provides a huge surface area for dye capture.

The material then proceeds to break the dye down into smaller, harmless molecules using the provided by sunlight, in a process known as “photocatalytic degradation”. Having removed the harmful dyes, the catalyst may simply be filtered from the cleaned water and reused.

While the photocatalytic degradation of dyes has been investigated for several decades, it is only relatively recently that researchers have developed materials capable of absorbing the visible part of the solar spectrum – other materials, such as titanium dioxide, are also able to break down dyes using solar energy, but their efficiency is limited as they only absorb higher energy, ultra-violet light. By making use of a much greater range of the spectrum, materials such as those used by the ESRI team at Swansea University team are able to remove pollutants at a far superior rate.

Both of the materials used in the study have attracted significant interest in recent years. Tungsten oxide, in particular, is considered one of the most promising materials for a range of photocatalytic applications, owing to its high electrical conductivity, chemical stability and surface activity, in addition to its strong light absorbance. As a low band-gap semiconductor, tantalum nitride is red in colour due to its ability to absorb almost the entire spectrum of , and therefore extracts a high amount of energy from sunlight to power the degradation processes.

However, the true potential of the two materials was only realised once they were combined into a single composite. Due to the exchange of electrons between the two materials, the test dye used within the study was broken down by the composite at around double the rate achieved by tantalum nitride on its own, while alone was shown to be incapable of dye degradation. In contrast to other leading photocatalytic materials, many of which are toxic to both humans and aquatic life, both parts of the composite are classed as non-hazardous .

The scientists responsible for the study believe that their research provides just a taster of the material’s potential. “Now that we’ve demonstrated the capabilities of our composite, we aim to not just improve on the material further, but to also begin work on scaling up the synthesis for real-world application.” said Dr. Jones. “We’re also exploring its viability in other areas, such as the photocatalysed splitting of water to generate hydrogen.”
