Mankind has done very well as a species. We have been to space, walked on the moon and discovered how to split the atom but we still depend on one of the oldest and dirtiest fossil fuels for energy.
It was reported that 1200 new coal plants are to be built with three – quarters of them to be located in China and India (no surprise there). Both China and India which are rising economic powerhouses with large populations to boot, have invested a lot in renewable technologies but have felt the need to return to the fossil fuel that has powered mankind for centuries. Germany which is one of Europe’s brightest renewable energy stars has decided to phrase out its nuclear plants and replace them with coal.
Unlike Mitt Romney who during the first presidential debate declared his love for coal (despite saying coal plants kill people in 2003) I am not a fan of coal for a variety of reasons. The effects of coal mining on the environment are extremely damaging and coal is the dirtiest fossil fuel in terms of its carbon dioxide emissions. There is also the human risk involved with coal use as coal workers are prone to all kinds of respiratory diseases due to particulate and heavy metal exposure.
So why then is coal making a very strong comeback despite fears by the UN that CO2 emissions are not being cut enough to stop climate change?
I guess the reasons why coal is still going strong are the same with why people are addicted to fast food.
1. Coal like most fast food is cheap and this is thanks to the global recession. The ongoing financial crisis has seen a fall in demand for products which results in reduced industrial activities. This then means that there is an oversupply of coal prompting governments to take advantage of this fact by building more coal plants.
2. Coal can be found almost everywhere. The same way you can find a fast food outlet with a five-minute walk in any direction is pretty much the same way you can find coal in almost any country. This limits the chances of a few countries controlling its price like OPEC does with crude oil.
3. Coal plants are cheaper and faster to build than nuclear power stations and most off-shore wind farms. You just pop them in a microwave for five minutes and voila, instant power. They are also more efficient than wind or solar which have to depend on site location to reduce intermittency issues.
A recent report by BP on the current energy reserves shows that our global coal reserves will last another 112 years compared to gas and oil which should last 63.6 years and 54.2 years respectively. This will mean that Old King Coal is going to be with us for quite a while.
So how do we deal with this situation?
The best way to live a healthy life is to cut out fast foods from your diet but in dire cases the next best thing is to make fast foods healthier. One way of doing this with coal is to avoid the use of lignite or brown coal which is the dirtiest of all coal (I guess it is like replacing vegetable oil with olive oil).
Another method which I am rooting for is called carbon capture and storage or CCS or short. This method takes all the carbon emissions from fossil fuel plants and pumps them into underground reservoirs. A rather interesting video about this technology can be seen below.
So what is the catch?
Well CCS has not be commercial viable and is till very much in its infancy. Its use with coal plants would have led to extremely high electricity prices but advances in CCS technology has shown that power plants with CCS could compete with nuclear and renewables in the next decade.
Now since majority of the new coal plants are being constructed developing countries, it will make sense for them to be equipped with CCS. This might increase the operating costs of the power plant but this is likely to be offset by the cheap price of coal. I also believe that the best way of funding CCS advancement in developing nations is to have industrialized nations pay for them and used the carbon credits earned to offset their emissions. The UK has several CCS projects ongoing and has pledged £60 million to promote CCS in developing countries.
So sadly, coal like fast food is mankind’s energy guilty pleasure and just like fast food we need to find ways to make it healthier.
