Major Qatari plant to double solar capacity by 2030: minister

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.

DGIST enhances quantum dot solar cell performance
by Riko Seibo
Tokyo, Japan (SPX) Oct 04, 2024
A research team led by Professor Jongmin Choi from the Department of Energy Science and Engineering at DGIST, in collaboration with Gyeongsang National University’s Professor Tae Kyung Lee and Kookmin University’s Professor Younghoon Kim, has developed a new method that significantly boosts the performance and longevity of perovskite quantum dot solar cells. Their innovative approach addresses a key issue: surface distortions on quantum dots that hinder solar cell efficiency.
Perovskite quantum dots are widely regarded as essential for next-generation solar cells due to their high light-to-electricity conversion efficiency and scalability. However, the process of replacing the “ligands” on their surface often causes distortions, akin to crumpled paper, that degrade solar cell performance.
The research team tackled this problem by introducing short ligands that firmly grip both sides of the quantum dots. This method effectively restores the quantum dot’s distorted surface, resembling the process of flattening crumpled paper. By smoothing the surface, they significantly reduced defects and improved both the performance and the stability of the solar cells. The power conversion efficiency rose from 13.6% to 15.3%, and the cells maintained 83% of their performance over 15 days, marking a major advancement in solar cell technology.
“Through this research, we could minimize surface defects on the quantum dots and stabilize their surfaces by newly adopting these amphiphilic ligands, thereby significantly improving the efficiency and stability of the solar cells,” explained Professor Jongmin Choi. He also noted the team’s intention to extend this approach to other photoelectric devices in the future.
This study, a collaborative effort by DGIST, Gyeongsang National University, and Kookmin University, was supported by the National Research Council of Science and Technology, the DGIST R and D Program, and the New Faculty Research Foundation at Gyeongsang National University. The findings were published in the ‘Chemical Engineering Journal’ on September 15, 2024.

Philippines’ Marcos opens first EV battery plant
by AFP Staff Writers
Manila (AFP) Sept 30, 2024
President Ferdinand Marcos inaugurated on Monday the first factory for electric vehicle batteries in the Philippines, calling it the “future” of clean energy.
The Australian-owned lithium-iron-phosphate factory aims to produce two gigawatt-hours of batteries per year by 2030, powering about 18,000 electric vehicles or nearly half a million home battery systems.
“We have worked very hard and tried to do our best to bring this kind of technology to the Philippines with a clear recognition that this is the future,” Marcos said in a livestreamed speech.
“As the first manufacturing plant in the Philippines for advanced iron phosphate batteries… (it) sets the stage for the Philippines to become a player in clean energy storage in our part of the world.”
Located in New Clark city north of Manila, the StB Giga Factory Inc. facility will create 2,500 local jobs and channel five billion pesos ($89.2 million) into the economy each year, Marcos said.
The investment aligns with the government’s efforts to “transition our country to renewable energy”, and would help Manila “entice more investors in renewable energy facilities in the country”, he added.

Fire breaks out at Chinese battery giant CATL plant
by AFP Staff Writers
Beijing (AFP) Sept 29, 2024
A fire broke out Sunday at a factory belonging to Chinese battery giant CATL, which supplies electric vehicle makers including Tesla, but only a “relatively small” impact on operations is expected, the company said.
A CATL spokesperson said no injuries or casualties had occurred at the plant in the coastal city of Ningde, and that “the reasons behind this accident are still under investigation”.
Emergency services were sent to the plant to fight the fire and to organise the evacuation of any people who were inside the 15,000 square metre (160,000 square feet) site, a statement by the Dongqiao Economic and Technological Development Zone said.
Firefighters were alerted to the blaze just before 11:30 AM local time (0330 GMT).
It was not immediately clear what was produced at the plant, CATL’s base in the eastern province of Fujian, but the company said the effect of the now extinguished fire would not be significant.
“The impact to CATL’s overall production operation is relatively small,” the spokesperson said.
Videos published by the Chinese business media outlet Cailianshe, and posted on the Weibo social network, showed parts of a large white building in flames with thick gray smoke rising into the air.
AFP could not immediately verify the authenticity of the images.
CATL was founded in 2011 and produces more than a third of the electric vehicle batteries sold worldwide for automakers that include Mercedes-Benz, BMW, Volkswagen, Toyota, Honda and Hyundai.
