Using batteries to retain energy from rooftop solar systems will be too expensive for at least two years, according to industry executives.
That means homeowners who add solar panels to save money on utility bills will continue to lose electricity during blackouts, even after an 80 percent decline in battery costs over the past decade.
Residential solar systems typically send power to the grid, not directly to the house, and do not run the home during a blackout. For batteries to save consumers money, stored energy must be drained daily, said Jamie Evans, who runs the US Eco Solutions unit for Panasonic Corp, which supplies lithium-ion cells for Tesla Motors Inc.
“Solar will need storage for grid stability,” Evans said on Thursday in an interview at the Solar Power International convention in Las Vegas. “Battery costs need to come down and regulatory structures have to change to really scale up.”
As residential solar become more common from California to New York, utility grids will increasingly become stressed without storage to ease supply and demand imbalances, he said.
For now, that means battery storage only makes economic sense for large businesses that get hit with extra fees when their power usage exceeds utility expectations.
These so-called demand charges can add up to half of a company’s utility bill, said John Carrington, chief executive officer of Stem Inc, a storage supplier backed by General Electric Co.
“Residential solar plus storage isn’t ready yet,” Carrington said in an interview. “Lithium batteries cost too much to be used for just backup power in an emergency.”
Taiwan Transport and Storage Corp (TTS, 台灣通運倉儲) yesterday unveiled its first electric tractor unit — manufactured by Volvo Trucks — in a ceremony in Taipei, and said the unit would soon be used to transport cement produced by Taiwan Cement Corp (TCC, 台灣水泥). Both TTS and TCC belong to TCC International Holdings Ltd (台泥國際集團). With the electric tractor unit, the Taipei-based cement firm would become the first in Taiwan to use electric vehicles to transport construction materials. TTS chairman Koo Kung-yi (辜公怡), Volvo Trucks vice president of sales and marketing Johan Selven, TCC president Roman Cheng (程耀輝) and Taikoo Motors Group
Among the rows of vibrators, rubber torsos and leather harnesses at a Chinese sex toys exhibition in Shanghai this weekend, the beginnings of an artificial intelligence (AI)-driven shift in the industry quietly pulsed. China manufactures about 70 percent of the world’s sex toys, most of it the “hardware” on display at the fair — whether that be technicolor tentacled dildos or hyper-realistic personalized silicone dolls. Yet smart toys have been rising in popularity for some time. Many major European and US brands already offer tech-enhanced products that can enable long-distance love, monitor well-being and even bring people one step closer to
RECORD-BREAKING: TSMC’s net profit last quarter beat market expectations by expanding 8.9% and it was the best first-quarter profit in the chipmaker’s history Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), which counts Nvidia Corp as a key customer, yesterday said that artificial intelligence (AI) server chip revenue is set to more than double this year from last year amid rising demand. The chipmaker expects the growth momentum to continue in the next five years with an annual compound growth rate of 50 percent, TSMC chief executive officer C.C. Wei (魏哲家) told investors yesterday. By 2028, AI chips’ contribution to revenue would climb to about 20 percent from a percentage in the low teens, Wei said. “Almost all the AI innovators are working with TSMC to address the
Malaysia’s leader yesterday announced plans to build a massive semiconductor design park, aiming to boost the Southeast Asian nation’s role in the global chip industry. A prominent player in the semiconductor industry for decades, Malaysia accounts for an estimated 13 percent of global back-end manufacturing, according to German tech giant Bosch. Now it wants to go beyond production and emerge as a chip design powerhouse too, Malaysian Prime Minister Anwar Ibrahim said. “I am pleased to announce the largest IC (integrated circuit) Design Park in Southeast Asia, that will house world-class anchor tenants and collaborate with global companies such as Arm [Holdings PLC],”
