Scientists' innovation for #IndoorSolarCells maximizes the use of light energy

Story by Science X staff
7/25/2024

"Chemists at Kaunas University of Technology (KTU), #Lithuania have synthesized materials that can improve solar elements for indoor use. Such photovoltaic cells, which can also be integrated into various electronic devices, generate electricity even in #LowLight conditions.

"Their study is published in ACS Applied Materials & Interfaces.

"Consumption of oil and gas results in an increase of atmospheric temperatures, leading to global #ClimateChange, currently labeled a #ClimateCrisis. To combat this problem, efforts are being made to use #renewable and environmentally friendly energy sources such as #wind, water and #SolarPower.

"'Wind and #hydropower energy are constrained by high costs and location dependency, while solar energy is flexible, efficient and relatively inexpensive. However, the energy from indoor light sources and natural light entering through windows is lost every day,' says Juozas Vidas Gražulevičius, Professor at the KTU Faculty of Chemical Technology and Head of the Chemistry of Materials research group.

"According to Prof. Gražulevičius, this can be solved by indoor #photovoltaics, which generate electricity even in low-intensity light conditions."

Falls Planning Board to weigh zoning change to spur #LoveCanal #SolarFarm

by RICK PFEIFFER | Jul 31, 2024

"The #NiagaraFalls Planning Board is expected to decide in September whether to recommend a zoning change that would allow the site of the worst #EnvironmentalDisaster involving #ChemicalWastes in U.S. history to be transformed into a large-scale, eco-friendly, #solar #RenewableEnergy project.

"Just three residents from the Love Canal neighborhood appeared at a board hearing Wednesday night on a request by city officials and the New York State Energy Research and Development Authority (#NYSERDA) to change the zoning of 16 acres of city-owned land, south of Colvin Boulevard, north of the LaSalle Expressway and between 93rd and 95th streets from R1-A (Single Family Residential) to OS (Open Space). The change would allow for the land that was once #HookerChemicalCompany’s Love Canal landfill to be reclaimed and developed into the Vincent Welch Build-Ready Solar project.

"That land was also once the location of the Griffin Housing Development [YIKES!] as well as the Love Canal."

Posted 9:01 AM, Aug 03, 2024

CHESAPEAKE, Va. — "At #SolarFarms in #Chesapeake and #VirginiaBeach, Dominion Energy has found an alternative option to a lawn mower; this one has hooves.

"'It’s an environmentally-friendly alternative, it’s innovative, it’s creative and they do a great job,' said spokesperson Tim Eberly. 'They can eat about 40 acres of grass and vegetation every few days.'

"The flock of 300 sheep and 180 lambs is tended to by a shepherd, along with guard dogs and herding dogs.

“'Our guardian dogs are with the sheep all the time," said Jess Gray with Gray's #Lambscaping. 'They protect the flock when we are not around.'"

[..]

"The goal of the project is to keep the grass below the panels to maximize output. At Bedford #SolarFarm in Chesapeake, one of the sites where the sheep currently graze, the energy generated powers 17,500 homes."

Closed loop? Reused #SolarPanels to power solar panel #recycling facility

Sean Wolfe
7.26.2024

"#SolarCycle, a solar recycling company, has installed an on-site solar farm made of reused solar panels that will power its industrial solar panel recycling facility.

"The reused panels come from decommissioned utility-scale solar farms and residential installations across the United States. SOLARCYCLE says the project serves as a model of how to power an industrial facility through renewable energy as the US ramps up domestic manufacturing capacity. It will also help to build a fully closed loop, ultra-low carbon solar industry in America.

"The 500KW system made from around 1,000 reused panels will provide around 50% of the electricity SOLARCYCLE uses to power their advanced recycling factory in #OdessaTexas. SOLARCYCLE’s plan is to expand this secondhand power plant to continue to generate more of the company’s energy demands, including its facilities in #MesaArizona, and #CedartownGeorgia. Two of SOLARCYCLE’s customers provided a significant percentage of the secondhand solar panels in use — #Ørsted from their own Texas utility-scale operations and #Sunrun, from their residential operations.

[...]

"Earlier this year, SOLARCYCLE announced it would invest an estimated $344 million into a new #SolarGlass manufacturing facility in #CedartownGeorgia. The company said it would be the 'first-of-its-kind' in the United States to use recycled materials from retired solar panels to make new solar glass.

"The facility will be located in Cedartown North Business Park, a Georgia Ready for Accelerated Development (GRAD) certified site in Cedartown. The plant, which will be the first of SOLARCYCLE’s facilities to manufacture glass in addition to recycling solar panels, was scheduled to begin construction this year and is expected to be operational in 2026.

"SOLARCYCLE currently operates two solar panel recycling facilities in the United States and says its recycling technology allows it to extract up to 95% of the value from used solar panels. SOLARCYCLE’s new plant in Georgia will make the company one of the first manufacturers of specialized glass for crystalline-silicon (c-Si) #photovoltaics in the U.S., with the capacity to make 5 to 6 GW worth of solar glass every year, it said. The glass will be sold directly back to the domestic solar manufacturers.

"Solar photovoltaics are often recycled the same way as glass, cars, computer monitors, TVs, or lighting, but the process only recovers about 80% of PV materials. Nonspecialized recycling is one of the challenges to achieving a circular economy for solar photovoltaics.

"While the moral incentive to recycle solar panels is clear, little financial incentive exists today. Recycling a solar panel ranges in cost from $20 to $30, while dumping the same panel in a landfill runs $1 to $2 – but SOLARCYCLE believes the cost to #landfill to be much higher when factoring in logistics costs."

Cutting #forests for #SolarEnergy ‘misses the plot’ on #ClimateAction

By Matthew Lynch
July 26, 2024

"As the world grapples with the urgent need to address #ClimateChange, the transition to renewable energy sources is often presented as a silver bullet. Solar energy, in particular, is championed for its potential to reduce #GreenhouseGas emissions and provide a sustainable alternative to #FossilFuels. However, a disturbing trend is emerging: in the quest to establish new solar farms, some regions are cutting down forests, raising questions about whether these actions truly serve the cause of climate action.

The Dilemma of Land Use

"The push for solar energy has led to significant land-use changes across the globe. In some cases, this has meant the clearing of large forested areas to make way for solar installations. Proponents argue that converting forest land into solar farms can produce clean energy and reduce dependency on non-renewable sources. However, this perspective overlooks the critical role that forests play in the global climate system.

"Forests act as vital #CarbonSinks, absorbing carbon dioxide from the atmosphere and storing it in their biomass and soil. When these forests are cleared, not only is this carbon storage capacity diminished, but the act of deforestation itself releases stored carbon back into the atmosphere, exacerbating climate change. In essence, the emissions produced by cutting down trees can offset the climate benefits of the solar energy generated on that land for years, if not decades.

#Biodiversity Concerns

"Beyond carbon emissions, cutting forests for solar farms poses a significant threat to biodiversity. Forests are home to a multitude of species, many of which are already endangered due to habitat loss, climate change, and human activity. The conversion of these habitats into solar farms disrupts ecosystems and can lead to local extinctions. The loss of biodiversity has far-reaching consequences, affecting ecosystem services such as #pollination, nutrient cycling, and #water purification, all of which are crucial for human survival.

A Holistic Approach to #RenewableEnergy

"The key to achieving meaningful climate action lies in adopting a holistic approach to renewable energy development. Rather than viewing solar energy installations solely through the lens of energy production, it is essential to consider the #environmental and #social implications of land-use decisions. This includes prioritizing #brownfield sites, such as abandoned buildings, #industrial lands, and degraded areas, where solar installations can occur without harming forests and other critical #ecosystems.

"Moreover, a combination of strategies should be pursued to maximize the benefits of solar energy while minimizing ecological impact. This could involve integrating solar panels into existing structures, promoting community solar projects, and investing in research on #agrovoltaics, which combines #agriculture with solar energy generation. Such approaches can help meet energy needs while preserving #NaturalLandscapes and promoting #biodiversity."

#RhodeIsland's largest #landfill #SolarFarm now online

Story by Kate Wilkinson
July 27, 2024

BRISTOL, R.I. (WPRI) — "Nearly 21,000 solar panels at the Bristol Transfer Station are now turning sunlight into power.

"And at more than 90 acres, it’s now the largest landfill solar farm in the state.

"Laura Frazier, the managing director of business development and strategy at NuGen Capital, said the site is expected to generate 8.7 million kilowatt hours each year.

"To put that in perspective, Frazier said a gas-powered car would have to drive 9 million miles to offset that much green energy, which is the equivalent of driving 375 times around the Earth.

"A ribbon cutting was held Thursday to celebrate the panels officially being connected to the grid. Frazier said the panels would create enough energy to power 700 homes.

"But Frazier said that green energy will actually be allocated to Toray Plastics, which the #NorthKingstown-based company bought out for the next 25 years.

"While Frazier said it can be more expensive to build on a landfill, the location has its perks.

"For example, a landfill offers a lot of open space, which she said means they don’t have to clear out any trees to install the panels.

"The project also didn’t face any opposition.

"'It doesn’t bother the neighbors,' she said. 'It’s not easily seen by any of them.'

"She also said the project received widespread support from local leaders.

"After eight years of planning, she’s finally glad to see this project come to life."

In a #Cleveland suburb, this old #CoalPlant will soon be replaced by a massive #SolarFarm

Inside Climate News
July 26, 2024

"#CoalFired power plant that started running more than a century ago is about to get a long-overdue retirement, and its electricity will be replaced by a solar farm and a #BatteryStorage system on an existing #brownfield.

"The project in #PainesvilleOhio, a suburb of Cleveland, is one of about two dozen clean energy and emissions-reduction initiatives across the country that are sharing $4.3 billion in funding announced on Monday by the #BidenAdministration.

"It was a happy day for Doug Lewis, Painesville’s city manager. He and his colleagues have been considering how to close the city-owned power plant and replace it with a cleaner alternative. They also have wanted to redevelop the site of a long-shuttered #chemical factory near the shores of Lake Erie.

"The federal government will now pay about $80 million to install solar and batteries on the former factory land and to beautify the rest of the brownfield by planting a #meadow of #wildflowers and constructing a #BikeTrail. The trail will provide a connection between Painesville and a regional trail that runs along the lake.

[...]

"The solar farm will have capacity of 35 megawatts and the battery storage system will have capacity of 10 megawatts. It will be capable of running for three hours at that level before recharging.

"The new construction will be on land that once was home to the Diamond Shamrock Corp. chemical plant, which operated there from 1912 to 1977 and occupied about 1,100 acres. The plant’s products included baking soda, chromium compounds, and hydrochloric and sulfuric acids.

"Since the site closed, the community and the federal government have gone through the slow and trying process of removing #pollutants to make it site safe for redevelopment.

The current project can serve as a case study for many things, including regional cooperation. Painesville, in Lake County, worked with officials in neighboring Cuyahoga County and the Cleveland city government to file an application with the federal government that included #RenewableEnergy projects for all of them."

Feds pick #Hanford #nuclear site for massive #SolarFarm

By Conrad Swanson
July 25, 2024

"While Washington struggles to contend with surging demand for electricity, federal officials on Thursday announced plans for a massive solar farm on the Hanford nuclear site.

"The U.S. Department of Energy is negotiating a real estate deal with Chicago-based #HecateEnergy, which would build a solar farm across 8,000 acres of federally owned lands on the heavily #polluted site.

"If built as planned, the project would have the ability to generate up to a gigawatt of renewable energy, and would rank among the largest solar installations in the country. That’s about enough energy to power half of Seattle City Light’s customers during record peak demand.

"The project would also include #battery storage, which is a critical component that allows electricity generated by solar power to be used at times when the sun isn’t shining.

"Producing #RenewableEnergy at the #HanfordSite would mark a substantial new chapter for the land.

"The site covers 560 square miles, nearly half the size of Rhode Island, said Sean O’Brien, executive director of the renewable nonprofit Energy Forward Alliance. For decades, the government made plutonium for nuclear weapons there.

"Despite its history — and contamination — large swaths of the site are not #radioactive, O’Brien said. And local organizations like his and the Tri-City Development Council share a vision for the place to be a national hub of clean energy generation.

"The solar array and battery storage would make up just one portion, albeit a large one, of the site’s renewable energy potential, Reeploeg and O’Brien said.

"The partnership between federal officials and Hecate — representatives for which could not immediately be reached for comment — could sidestep major hurdles these types of massive projects face, said Glenn Blackmon, manager of Washington’s Energy Policy Office."

Scientists test #agriculture and #SolarEnergy on #Illinois #farms

Two experiments in the state are measuring which crops could grow well under these panels.

By Juanpablo Ramirez-Franco
Jul 18, 2024, 2:58pm EDT

"Thousands of #wildflowers are blooming under rows of solar panels in eastern Illinois. #Milkweeds, #BlackEyedSusans and native #PrairieGrasses catch the sunlight that streams past solar panels on one end of this 54-acre property near Champaign.

"'Obviously, this setting is not perfect for the farming system,' D.K. Lee, a professor of crop sciences at the University of Illinois Urbana-Champaign, said about the narrow space between solar panel arrays.

"But this experimental station called #SolarFarm 2.0 could help UIUC scientists determine whether the marriage between Midwestern agriculture and solar power will be a happy one. Researchers are piloting how crops such as grains and #soybeans used primarily to feed livestock grow with solar panels obstructing their full view of the sun. The counterintuitive practice is called #agrivoltaics, a nascent industry that partners solar developers looking for large plots of land and farmers looking to make additional income.

"That’s why two parallel experiments are underway here to find out what can grow and thrive under solar panels. To hit the ambitious clean energy targets set by state and federal officials, solar power will have to increase close to seven times over current capacity by 2035. That will mean millions of acres devoted to solar power — many of which could be in America’s #farmlands. But to make sure that agricultural communities aren’t left behind by the clean energy transition, scientists want to know what it will take for life to persist beneath solar panels — potentially a first step for farmers and solar power to co-exist.

"'We can only farm about 70% of the land here,' said Bruce E. Branham, professor of horticulture at UIUC. 'So we’ve got 30% of the land that would be farmed in full sun that is just vacant.'

"But in just two years and despite physical constraints, initial findings suggest that the #sorghum grain could be a promising crop to grow alongside solar panels. Branham said that so far it appears that combining sorghum with solar panels has resulted in a 59% increase in efficiency. And wildlife, including #birds and #bees, are flocking to the improved habitat. It’s a good start, but there’s still ways to go before solar farms like these are generating serious energy.

"'This is a 54-acre site, and we’re getting 12 megawatts,' Banham said. 'A lot of power plants are much, much greater than that.'

"In all, Solar Farm 2.0 produces close to 1% of the generating power of the #ClintonPowerStation, a #NuclearPowerPlant just a 45 minute drive east. But for Banham and others, this presents an opportunity to combine Midwestern row crops with solar power to generate enough energy to compete with #FossilFuels and other clean energy alternatives."
