Alstom, coal is also an energy future
History may repeat itself. While coal seems to belong to our industrial past, this energy source could again be used to power our electricity needs. Philippe Joubert, president of Alstom Power believes that the development of this fuel, better used and combined with CO2 capture technologies could contribute more to cover the energy needs of the planet and especially in Asia.
lefigaro.fr – You have created a joint venture with Shanghai Electric in the areas of boilers for coal-fired power plants, creating the market leader. Bet you on development of coal power plants?
Philippe Joubert – Coal-fired energy efficiency and environmental recognition are booming, particularly in Asia.However, I have a vision for long-term market and I believe that all technology is integral to the balance of the world. Nuclear, solar, hydropower, coal plants … there is no quick fix. All technologies are needed to produce electricity.
The coal could they not benefit from the current debate raised by the accident at the plant in Fukushima? Several countries, like Germany, have expressed their willingness to abandon nuclear …
Today we actually build many coal plants and gas. An evolution of the global energy mix is thus expected. However, we favor a diversification of energy sources.
And we must relativize the importance of nuclear energy market.This energy source is ultimately less than 10% of all energy produced in the world and is contested in countries where this energy is not a majority in the energy mix. For example, the German market represents less than 21 gigawatts of nuclear energy cons 392 gigawatts for the global market. For example, countries dependent on nuclear power, as the U.S. and France respectively produce about 100 gigawatts and 70 gigawatts.
Coal will remain there a piece of the global energy mix?
Over 40% of the electricity produced in the world based on coal fast cash advance. Asia currently consumes almost 80% of world coal production. But the real issue today is how the emerging cover their soaring energy needs, where those of the United States or Europe have low growth.Development of coal power plants seems to agenda.
Coal plants are very emitting CO2. Can we thus generate electricity without CO2?
We can produce electricity from coal without emitting CO2. But the latest plants can significantly reduce these emissions. In parallel, we develop carbon capture and storage of CO2 (CCS). This is to recover the CO2 and storing it underground (in underground cavities emptied during gas extraction, ed.) The cost of electricity through a coal power plant equipped with this device is however still much higher than a conventional plant. But we are at the beginning of this new technology.
Mined since the eleventh century, coal still has reservations
Coal is the fuel of superlatives.Mined since the eleventh century, it is one of the oldest energy sources. And even today it remains the most widely used fossil fuel in the world: it can produce more than 40% of worldwide electricity. Many countries, primarily the emerging countries, still use it as a primary energy source like South Africa, China, Australia or Poland. Moreover, world coal reserves are found in many countries, no less than 70. The main reserves are in the United States, Russia, China and India. They are estimated at over 984 billion tons. Thus, if consumption is maintained in the state, known coal reserves could last for nearly two centuries, so an oil shortage looming for 2050.
