Atlas reveals solar energy potential in Germany

by Robert Schreiber

Berlin, Germany (SPX) Jun 06, 2024

Which roofs are suitable for solar panel installations? Where are photovoltaic systems already in place? How much output could be achieved with solar panel arrays at specific locations? A map developed by the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) provides the answers. DLR’s researchers used machine learning methods to process current aerial photographs and geodata, enabling them to determine solar energy potential for the entire stock in Germany of around 20 million buildings. Results for the whole country are publicly available at eosolar.dlr.de.

The Solar Atlas is being presented at ILA in Berlin, where DLR is showcasing its research and development work in aeronautics, space, energy, transport, digitalisation and security.

“Policy makers need precise information on the current inventory and growth potential in order to devise and implement effective strategies for expanding photovoltaic systems on roofs,” explains Anke Kaysser-Pyzalla, Chair of the DLR Executive Board.

“The satellite-derived information provided by DLR supports the energy transition and drives forward innovative products and business models. The DLR Solar Atlas shows how Earth observation can be used successfully for climate protection and the sustainable expansion of energy generation.”

Multiple terabytes of data evaluated

Within the framework of the EO Solar project, researchers from the DLR Earth Observation Center (EOC) are evaluating and combining several terabytes of data from various sources to outline the current situation in Germany. These include digital, distortion-free aerial photographs with a resolution of 20 centimetres and high-quality surface models with a resolution of one metre, provided by the Federal Agency for Cartography and Geodesy.

“To evaluate the current expansion potential for solar energy, we calculate the possible electrical output based on the hours of sunshine, radiation intensity, orientation of roof surfaces and shading from neighbouring buildings or vegetation,” says Annekatrin Metz-Marconcini, who heads the EO Solar project.

“DLR has also developed a process using artificial intelligence that enables us to identify roofs with existing solar panels anywhere in the world based on high-resolution remote sensing data. In Germany, we have included the Core Energy Market Data Register in the information that we use.” The Core Energy Market Data Register lists all registered German solar panel installations and is updated on a daily basis.

Rather than building models, EO Solar uses digital terrain models, including those generated with the help of aircraft and satellites. These models automatically take account of shading from trees and the surrounding area, and the process can be extended to countries that do not have building models. Other than the roofs of buildings, the solar energy potential of open spaces can also be calculated using the same methodology and then taken into account for planning purposes.

Solar potential identified for municipalities, districts and federal states

Existing solar panel registers for federal states, districts or municipalities often differ in the level of information included, may lack detail or be limited to certain areas. By contrast, the DLR Solar Atlas provides an up-to-date, systematic mapping of the whole of Germany and as such offers policy makers and planners alike a basis for promoting the targeted expansion of photovoltaic systems.

DLR researchers have already created a similar map for Austria as part of an ESA project. For data protection reasons, it is not possible to map solar expansion potential for individual buildings on a publicly available website in Germany, so the expansion potential is shown at municipal, district or federal state level. The publicly accessible website eosolar.dlr.de has recently been set up for this purpose.

Argonne to lead National Energy Storage Research Hub

by Clarence Oxford

Los Angeles CA (SPX) Sep 05, 2024

The U.S. Department of Energy (DOE) has selected Argonne National Laboratory to lead the newly established Energy Storage Research Alliance (ESRA), a national hub focused on advancing energy storage technologies. The ESRA, co-led by DOE’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Pacific Northwest National Laboratory (PNNL), is one of two new Energy Innovation Hubs announced by the DOE.

Bringing together nearly 50 leading researchers from three national laboratories and 12 universities, ESRA aims to address the most critical challenges in battery technology, such as safety, high-energy density, and the development of long-duration storage solutions using cost-effective and abundant materials. The initiative is designed to push the boundaries of energy storage science, fostering innovation and strengthening the competitive edge of the U.S. in this crucial field.

“The demand for high-performance, low-cost and sustainable energy storage devices is on the rise, especially those with potential to deeply decarbonize heavy-duty transportation and the electric grid,” stated Shirley Meng, ESRA director and chief scientist at the Argonne Collaborative Center for Energy Storage Science. “To achieve this, energy storage technology must reach levels of unprecedented performance, surpassing the capabilities of current lithium-ion technology. The key to making these transformative leaps lies in a robust research and development initiative firmly grounded in basic science.”

Leveraging decades of investment in fundamental science, ESRA will focus on transformative discoveries in materials chemistry, a deeper understanding of electrochemical processes at the atomic level, and establishing the scientific foundations necessary for major advancements in energy storage technology.

“ESRA creates an energy storage research ecosystem with the mission to rapidly innovate, shorten the time between basic discovery and technology development, and train the next-generation workforce,” commented Bryan McCloskey, ESRA deputy director for scientific thrusts and a faculty engineer at Berkeley Lab.

The success of ESRA’s efforts will lead to the development of high-energy batteries that are fire-resistant, capable of providing long-duration storage for multiple days, have a lifespan of several decades, and are constructed from low-cost, widely available materials.

“ESRA will pave the way for innovative energy storage solutions that drive both U.S. prosperity and security,” said Argonne Director Paul Kearns. “As the lead laboratory for ESRA under the Department of Energy’s Office of Science, Argonne takes pride in spearheading this collaborative effort that unites world-leading experts and taps the impressive scientific resources available in national labs and academia.”

The DOE has committed up to $62.5 million in funding for ESRA over the next five years.

In addition to its research goals, the Argonne-led hub will prioritize training a diverse, next-generation battery workforce to meet future manufacturing demands. This will be achieved through innovative training programs that involve industry, academia, and government partnerships.

“Cultivating a diverse workforce dedicated to safeguarding America’s energy resilience is key to ESRA’s mission,” noted Wei Wang, ESRA deputy director for crosscuts and director of the Energy Storage Materials Initiative at PNNL. “Through our strategic equity and inclusion initiatives, we plan to create a robust training ground for energy storage science from the undergraduate to postdoctoral levels.”

With Berkeley Lab and PNNL as co-leads, the ESRA collaboration brings together comprehensive expertise across the energy storage spectrum. Their state-of-the-art capabilities in technology discovery, modeling and simulation, and materials synthesis and characterization complement those of Argonne, setting the stage for significant advancements in energy storage.

Argonne is joined by 14 partners in this initiative, all of whom are deeply involved in ESRA’s scientific endeavors, governance, strategic development, and the training of the next generation of battery scientists and engineers. This collaboration among national laboratories and universities is vital for discovering new materials, accelerating the development of technology, and commercializing new energy storage innovations.

UN’s Guterres says China-Africa ties can drive ‘renewable energy revolution’

by AFP Staff Writers

Beijing (AFP) Sept 5, 2024

United Nations Secretary-General Antonio Guterres told African leaders Thursday that expanding ties between China and the continent could “drive the renewable energy revolution”.

Guterres and more than 50 African leaders are attending this week’s China-Africa forum, according to state media.

Guterres told the gathering that “China’s remarkable record of development — including on eradicating poverty — provides a wealth of experience and expertise”.

“It can be a catalyst for key transitions on food systems and digital connectivity,” he said.

“And as home to some of the world’s most dynamic economies, Africa can maximise the potential of China’s support in areas from trade to data management, finance and technology,” Guterres added.

Guterres also told the leaders it was time to correct “historic injustices” against the continent.

“It is outrageous… that the continent of Africa has no permanent seat on the Security Council,” he said.

Major Qatari plant to double solar capacity by 2030: minister

by AFP Staff Writers

Doha (AFP) Sept 1, 2024

A large new solar plant planned in Qatar will double the Gulf emirate’s previously projected renewable energy capacity by 2030, Qatari Energy Minister Saad al-Kaabi announced on Sunday.

The photovoltaic farm, which will be built in the Dukhan area some 80 kilometres (50 miles) west of the capital Doha, will increase the gas-rich state’s solar production capacity to four gigawatts by the end of the decade, Kaabi said.

The plant “that will be established in Dukhan area will produce 2,000 megawatts, which is twice more than the capacity of Qatar’s production of solar energy of the current projects,” the minister, who is also chief executive of state-owned QatarEnergy, said.

In October 2022, Qatar inaugurated its first large-scale solar farm at al-Kharsaah, west of Doha. The emirate announced in August of the same year another solar project with two plants at Ras Laffan in the north.

Through the combined projects, including at Dukhan, Qatar would achieve “4,000 megawatts of clean energy by 2030”, Kaabi said.

This will “constitute 30 percent of the total production of energy of the state of Qatar” with a yearly reduction of “4.7 million tonnes of CO2 emissions,” he added.

Kaabi said the existing projects should produce 1.7 gigawatts of energy “in first quarter of next year, or early next year”.

The energy minister also announced plans to more than double Qatar’s urea production making the country the largest producer of the fertiliser in the world by the end of the decade.

He said Qatar would “maximise the production of chemical fertilisers” through “a complex with global standards” which would “increase our production capacity from 6 million tonnes annually to more than 12.4 million tonnes annually”.

Qatar is one of the world’s top liquefied natural gas producers alongside the United States, Australia and Russia. Natural gas is a major ingredient in urea manufacturing.

In February, Qatar announced plans to expand its output from its North Field project, saying it will boost capacity to 142 million tonnes per year before 2030.

Over the past year, Qatar has inked a series of long-term LNG deals with France’s Total, Britain’s Shell, India’s Petronet, China’s Sinopec and Italy’s Eni among others.
