Clean coal technology: A design for environment

Cebu Energy Development Corporation’s vision for 2010

THE key priorities of the Department of Energy (DoE) are energy efficiency and energy sustainability. With this, a group of companies in the energy industry have come together to take these priorities a step further by introducing a new energy technology system that, despite it being fossil-fuel based, assures cleaner production, encourages and employs recycling measures including the treatment and reutilization of pollutants, and provides 99.9 percent efficiency in capturing particulate emissions.

Clean Coal Technology (CCT) hinged on the operation of a Circulating Fluidized Bed (CFB) system shall be utilized by the Cebu Energy Development Corporation (CEDC) in its 246-megawatts clean coal-fired power plant presently being constructed in Toledo City in the province of Cebu.

The CEDC is a joint venture of Global Formosa Power Holdings, Inc. and Abovant Holdings, Inc. envisioned to successfully address the need for baseload, quality and affordable electrical power come 2010 onwards thereby contributing to further economic growth of Cebu Province and more jobs.

What exactly is Clean Coal Technology?

Clean Coal does not mean zero emissions or zero waste. This is the most common misconception that people have when they hear about Clean Coal.

Clean Coal Technology is simply ensuring that coal emissions and wastes are reduced in each and every step or process of generating electrical power––from covered delivery trucks that are washed down as they leave the power plant, to enclosed conveyors and coal yards, ash ponds, lined with several layers of protective textile, waste water treatment facilities, heat recovery and energy savings systems, publicly accessible 24-hour real-time emission monitoring, pollutant analysis and environmental forensics, and the use of the CFB as well as an electrostatic precipitator to capture particulate emissions.

In economies like Taiwan, Clean Coal Technology is a primary technology for energy conversion as it extends the usability of coal compared to its predecessors and significantly reduces key toxic emissions.

CCT, through the use of CFB, provides for a wide range of fuel adaptability (from paper sludge to low-grade coal to help generate electricity at a lower cost,) high combustion efficiency and low furnace temperature causing low emissions of sulfur dioxide or SO2 (removal efficiency of 95 percent and higher for SO2), nitrogen oxide (NOx) and dust or total suspended particulates.

CFB burns coal more efficiently (98-99 percent carbon burnout) compared to older systems such as coal-fired thermal power plants in Cala, Pagbilao, Sual and Naga, all in Cebu province.

CEDC is guided by the Philippine Clean Air Act of 1999 and aims to meet World Bank’s standards of emissions for new coal-fired power plants in the application of this technology.

CEDC also intends to do its part in carbon-offsetting by creating a mini forest park adjacent to the power plant for the enjoyment of the surrounding communities.

In line with its commitment towards resource efficiency and sustainability, plans to sell fly ash and bottom ash as material for local cement production are being developed.

Led by its president, Jesus N. Alcordo, CEDC promises to be electricity generator of choice for Cebu.

CEDC is committed to energy efficiency, reliability and environmental sustainability by using Clean Coal Technology and by setting higher standards for itself than expected by its peers in the industry and environmental sector.
