Since time immemorial, the earth has been blessed with an endless cycle of rain falling from the sky, onto the watershed, flowing as run-off into the rivers, lakes, groundwater, and finally into the oceans where it picks up the Sun’s limitless energy to evaporate again and join the clouds, only to be cooled by the shadow of the earth as cold winds precipitate the saturated vapors that falls again to repeat the cycle.

Is Advanced Clean Coal Technology the Answer to our Global Power Problem?
Remaining Life of Fossil Fuels (oil, natural gas, coal)
Recent events have thrust lately renewed interest in “advanced clean coal” technologies to provide additional power generation capacity in view of dwindling and expensive oil supplies (remaining life 39 years), natural gas (61 years). World wide coal reserves are expected to last over 231 years (remaining life = reserves / extraction rate).
However, due to concerns arising from pollution (emission of sulfur as SO2, toxic ash and heavy metals) and climate change (emission of CO2 greenhouse gases), the utilization of coal for power generation has spurred researches leading to the development and commercialization of so called “advanced clean coal” technologies.

Shall We Go Nuclear?
Oil Crisis of 2008
The recent oil crisis which saw the rise of crude oil prices to a peak of $147 per barrel in the world market and its attendant effect on raising electricity prices in the Philippines at a rate higher than its competitor economies in the region has brought forth renewed calls to review policies relative to the development of the Philippine Nuclear Industry.
Revive the 600 MW BNPP?
In particular, attention has been directed toward reviving the mothballed 600 MW Bataan Nuclear Power Plant (BNPP) constructed by the National Power Corporation in the early 1980’s. In its desire to be part of the growing list of nuclear power generation nations in the world, the Philippines implemented a national agenda that included the construction of the 600 MW BNPP in tandem with the 300 MW Kalayaan Pumped Storage Hydro Plant in 1982. The pumped storage would serve as a dummy load of the nuclear plant during off-peak periods at night in order to allow for a constant and stable generation of 600 MW of nuclear power throughout the entire day. (In the absence of the “cheap” nuclear electricity, the Laguna Lake water is pumped uphill to Lake Caliraya at night using geothermal, coal and sometimes expensive oil-based electricity in order to have adequate baseload capacity during day-time peak hours.)
Numerous Issues Hounded the BNPP
Unfortunately, or for reasons only Providence could imagine, the BNPP has been hounded with controversy ranging from allegations of overprice and corruption in the construction of the power plant, unsafe plant location being near an inactive volcano (Mt. Natib), being located near an active fault, possible long-term environmental harm to the nearby residents and Luzon populace in the event of accidental release of radio active gases and materials arising from a nuclear accident, unsafe plant design (pressurized water reactor or PWR), expensive electricity arising from its high cost per kW due to overprice (one 600 MW plant for the cost of two 600 MW plants as originally conceived), and of course, how to economically and safely dispose of the spent nuclear fuel material, radioactive control rods and other materials exposed to high levels of radiation.

TECHNOLOGY ROADMAP: VISION – robust portfolio
In its “Electricity Supply Roadmap, January 1999”, EPRI clarified the ultimate goal or vision for the power generation industry worldwide:
A robust portfolio of technologies that provide reliable, affordable electricity, with capacity and resource flexibility to meet global market needs – on a sustainable basis – with acceptable environmental impacts.
Implementation will vary from developed and developing countries, from region to region, based on indigenous resources and on economic, environmental and political factors, hence, the need for a portfolio of solutions.
Power Generation Technology Roadmap : Two Destinations
The EPRI Roadmap suggests destinations and identifies R&D opportunities over two nominal time frames:
Twenty years from now (2020) – to assess near-term opportunities and the technical foundations we will draw upon to reach 2050 goals
Fifty years from now (2050) – to encompass truly new and innovative technologies, not simple extrapolation of today’s development efforts. 50 years is deemed to be long enough to allow for capital stock turnover and widespread adoption of new technology. It also provides milestone for gauging progress toward broader goals for energy use by 2100.
