Green tech developers show true colours move

These solutions, which could enable the mass transit of more two million passengers per day, were highly energy efficient and would lead to 1,100 tonnes of carbon dioxide (CO2) savings per day, said Siemens Vietnam CEO Erdal Elver.

He said with its technology, the metro, largely financed by the German government, could use mainly recyclable materials. Especially, metro line 2 would save more than 400,000 tonnes of CO2 every year.

The firm also wishes to provide environmentally-friendly technology and solutions for many more power and steel projects in Vietnam. It has successfully equipped a new bar mill at Ba Ria-Vung Tau province-based Thep Viet Steel Corporation’s Ba Ria 450,000 metric tonne capacity facility with electrical and automation systems.

These systems would help the facility reduce injected carbon by 20 to 30 per cent, while trimming energy consumption, operating costs and CO2 emissions. Siemens is also the turnkey contractor for major power plant projects like Phu My 2-1 extension, Phu My 3, Ca Mau 1+2 and Nhon Trach 2. With total output of about 3,000MW, they are the most efficient plants in the country and contribute considerably to the reduction of green-house gas emissions.

Meanwhile, Danish-backed FLSmidth Vietnam general manager Rune Hurttia said the firm was keen on cooperating with Vietnam-based cement-makers via its latest energy efficient technologies. “The new technologies will bring significant changes and greener production practices into Vietnam’s cement industry,” Hurttia said.

These technologies are a waste heat recovery system and waste incineration in cement plants. Using the waste heat recovery system, plants can upgrade existing production lines with energy efficient and cost-saving technology which would generate electricity from the spare heat in the exit gases.

Shell Vietnam said Vietnam boasted so many opportunities to apply new and green technologies as the country was building more and more infrastructure which would protect the environment for the next 30 – 50 years.  Shell Vietnam’s country chair and general director Thanh Le said Shell was combining with Vietnam’s government and Vietnam Chamber of Commerce and Industry to coin energy efficient programmes.

“We would like to promote Shell’s advanced technology and products such as liquefied natural gas (LNG) in power generation. Environmental benefits of natural gas-fired power are tangible, substantial and immediate,” he said, adding that the Vietnamese government would play a pivotal role in attracting foreign environmental-friendly technology.
