Carbon capture techniques will continue to be a top priority for Taiwan Cement Corp’s (台灣水泥) Hualien-based subsidiary Ho-Ping Power Co (和平電廠), chairman Nelson Chang (張安平) said yesterday at a news conference in Hualien, citing reductions in production costs and new business potential for growing microalgae as benefits.
Taiwan Cement, the nation’s largest cement maker, has since 2011 been involved in a carbon capture project at Ho-Ping Power through collaborations with the Industrial Technology Research Institute (ITRI, 工研院) since 2011. The project aims to reduce carbon dioxide emissions and promote a circular economy.
PILOT PLANT
The pilot plant at Ho-Ping Power is the world’s largest facility to employ the calcium looping process for carbon capture, the company said.
The calcium looping capture process uses calcium oxide, a common ingredient in cement products, as a sorbent for carbon dioxide and could reduce the carbon dioxide capture cost from more than US$45 per tonne to US$30 per tonne, the company said.
Taiwan Cement and ITRI last year signed an agreement to extend their technical cooperation on the project.
The pilot production lines are likely to begin commercial operations before 2022, Chang said, citing difficulty scaling up the project.
The firm has allocated a capital budget of nearly NT$70 million (US$2.3 million) to the technique in the past few years and plans to spend NT$10 million per year in the future.
Apart from lowering production costs, carbon capture technology also turned out to have unexpected business potential after the company found that captured carbon dioxide could be used to grow microalgae.
MICROALGAE
Microalgae — a major source of biofuel — can also produce astaxanthin, a key ingredient in high-value skincare products and medicines.
Taiwan Cement said it is seeking business partners to promote skincare uses for astaxanthin, instead of launching its own brand.
The company needs to stay focused on its core business and has no plans to tap into the retailing industry, Chang told the Taipei Times.
Taiwan Cement’s long-term goal was to transform itself from a traditional cement maker into a “green” service provider, the company said.
Revenue generated by the company’s two major energy subsidiaries, Ho-Ping Power and Moli Energy Corp (能元科技), made up nearly 15 percent of Taiwan Cement’s total sales last year, while its cement business contributed 73 percent, data showed.
‘GREEN ENERGY’
Meanwhile, the company plans to launch a large-scale “green” energy project at the Changhua Coastal Industrial Park (彰濱工業區), Chang said.
He declined to provide details on the new project, saying only that it is to include wind power generation.
Many companies put their unused factories up for sale, but the company hopes to “revitalize” its abandoned facilities, Chang said.
Real estate agent and property developer JSL Construction & Development Co (愛山林) led the average compensation rankings among companies listed on the Taiwan Stock Exchange (TWSE) last year, while contract chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) finished 14th. JSL Construction paid its employees total average compensation of NT$4.78 million (US$159,701), down 13.5 percent from a year earlier, but still ahead of the most profitable listed tech giants, including TSMC, TWSE data showed. Last year, the average compensation (which includes salary, overtime, bonuses and allowances) paid by TSMC rose 21.6 percent to reach about NT$3.33 million, lifting its ranking by 10 notches
SEASONAL WEAKNESS: The combined revenue of the top 10 foundries fell 5.4%, but rush orders and China’s subsidies partially offset slowing demand Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) further solidified its dominance in the global wafer foundry business in the first quarter of this year, remaining far ahead of its closest rival, Samsung Electronics Co, TrendForce Corp (集邦科技) said yesterday. TSMC posted US$25.52 billion in sales in the January-to-March period, down 5 percent from the previous quarter, but its market share rose from 67.1 percent the previous quarter to 67.6 percent, TrendForce said in a report. While smartphone-related wafer shipments declined in the first quarter due to seasonal factors, solid demand for artificial intelligence (AI) and high-performance computing (HPC) devices and urgent TV-related orders
Prices of gasoline and diesel products at domestic fuel stations are this week to rise NT$0.2 and NT$0.3 per liter respectively, after international crude oil prices increased last week, CPC Corp, Taiwan (台灣中油) and Formosa Petrochemical Corp (台塑石化) said yesterday. International crude oil prices last week snapped a two-week losing streak as the geopolitical situation between Russia and Ukraine turned increasingly tense, CPC said in a statement. News that some oil production facilities in Alberta, Canada, were shut down due to wildfires and that US-Iran nuclear talks made no progress also helped push oil prices to a significant weekly gain, Formosa said
