Spend To Quench Coal Thirst
By Debra Tan 7 August, 2013
Debra Tan argues that a solution to thirsty coal lies in spending in aggressive water savings tech
Already down, coal takes another hit with Greenpeace’s recent spotlight on the water intensive and polluting nature of the coal-to-chemicals industry. So with the price of coal falling and the market flooded with excess coal, is this it for coal? Surely all good news for water as production of coal looks set to slow down. Maybe in the short term but in the long run, coal production in China is set to grow.
Neil Dhar, Head of Hard Commodities of Noble Group (one of the largest traders of coal globally) said that China’s coal capacity is growing at 5% per annum and expects China’s coal production to hit 5.8 billion tonnes by 20201. The 12FYP target at 2015 is 4.1 billion tonnes. We argued in our previous article that the only way to ensure there is enough water to sustain this level of coal growth is through investment:
- consolidation of coal Town Village Enterprises (generally less water efficient and more polluting – currently 35% of China’s coal production);
- importation of more coal;
- coalmine-grab strategies outside of China; and/or
- improve water efficiency, introduce wastewater recycling and water reuse
“a large portion of coal is still expected to be produced by Chinese-controlled companies to ensure energy security.
… China’s only real option to quench coal thirst is to adopt aggressive water savings strategies in the extraction and preparation of coal”
Zhou Dongzhou, Secretary to Board of China Coal, confirmed the push for consolidation. He said at a presentation2 that 30% of Chinese coal companies were running at a loss and that the government were encouraging the consolidation of coal production into the major coal bases.
Importation of coal will only make China more vulnerable to external shocks and given that coal is the vanguard, whilst coal imports will rise, a large portion of coal is still expected to be produced by Chinese-controlled companies to ensure energy security. Coalmine-grabs by Chinese companies are preferable, but with the likelihood of opposition by host countries, China’s only real option to quench coal thirst is to adopt aggressive water savings strategies in the extraction and preparation of coal.
The 24 bathtubs of water to mine and produce one tonne of coal (2.3m3/t for extraction & 2.5m3/t for washing) could be halved with technology investments.
Aggressive water savings strategies – the only way out
HSBC’s report “China Coal & Power: The water-related challenges of China’s coal & power industries” published in June 2103 confirms our views. Scenarios analysis by HSBC show that the water use caps set by the government for 2015, 2020 and 2030 are too aggressive unless water-savings strategies are adopted.
The bulk of water savings by 2030 are expected to come from:
- coal production: water use in coal extraction falling to 1.15m3/t and coal washing to 1.17m3/t (11.6 bathtubs); and
- coal fired power generation with water withdrawals falling from 28.5m3 of water per MWh to 12m3 per MWh
However, the report warns that “for coal-to-liquids plants, we believe only a modest improvement in water usage is possible. This is relatively new technology and we believe it could be difficult for the industry to lower its water footprint while the focus is on expansion.”
I will not expand on the water intensive nature of turning coal into liquid fuel as Calvin Quek of Greenpeace has discussed this extensively in “Coal-to-Chemicals: Shenhua’s Water Grab”.
China spend on mining – a mere drop
During a CLSA U roadshow on the “Water & Coal” report issued in April 2013, it was interesting to note that not one of over 30 institutional funds based in Hong Kong and Europe challenged the existence of water risk in China. How to invest around thirsty coal was the favourite question. Given the above analyses and current groundwater crackdown maybe companies that clean up mine tailings or help improve water efficiencies may be a good start. Increased spending appears inevitable – after all, “Energy savings/ Environmental Protection” is a 12FYP new strategic emerging industry.
Currently, the three coal majors, China Coal, Shenhua Energy and Yanzhou Coal spend less than 1% of their total revenue on environmental protection. In 2011, these three collectively spent RMB2.27 billion or USD345million on the environment. This might look like a lot, but note that this is the environmental spend of which water is a component. The water spend was not disclosed.
Even then, US$345 million spend on environment by the three coal majors pales in comparison to the spend on water by a single company, Newmont Mining: US$440million on water reservoirs for downstream users, as part of its bid to regain their mining license for its Yanacocha Conga gold mine in Peru.
USD440million might seem steep compared to China’s spend but it is a fraction compared to a potential write-off of the mining operations worth US$4.8 billion. The mining licence was revoked by Peru’s National Water Authority on the grounds of a poor historic record polluting the Rio Grande.
Elsewhere, in South Africa, Anglo-American is working on phase 2 of the eMalahleni water reclamation plant, which treats groundwater from mining operations and provides water to the local community. Phase 2 plans to increase the capacity of the plant and will cost Anglo American a further R732 million (US$73.5 million); Phase 1 was a R300 million (~US$30 million) initiative with BHP and the local government. (See a graphic of how this works here).
“People laughed at us when we said that water would become more important to the mining industry than minerals,”
Anglo American’s Eastern Limb Development general programme manager Dean Pelser
Anglo American is also constructing a 600 kilometre water supply pipeline to their platinum mines located in the Limpopo province of South Africa. The pipeline which will provide access to reliable potable water for 1.4 million people for the first time, will be constructed in phases and is due to complete in 2020. According to their webpage describing the project, “The scarcity of [water] is one of the mining industry’s greatest risks and threatens the development and sustainability of our operations in this area.”
Anglo American has also committed US$96m to build a desalination plant at the Mantoverde copper mine in Chile to provide 100% of the region’s current and future water needs.
It’s not just in coal, the total spend on water by the mining industry in China is low. According to Global Water Intelligence (GWI)’s 2011 Water in Mining Report, China’s spend on water-in-mining was US$203 million compared to US$1.5 billion by Australia. Even Peru spent close to US$800 million. The report forecasts that water-related infrastructure for the industry will rise to $13.6 billion in 2016 from $7.7 billion in 2011 if current trends continue. (More on this report by GWI including expenditure by type of water infrastructure here.)
Blindsided by outliers – a wetter North, floods & end users
“we are not worried at present, our mines are underground and therefore we are able to make use of deep groundwater”
Zhou Dongzhou, China Coal
When asked about whether China Coal is worried about water, Zhou Dongzhou, of China Coal responded saying “we are not worried at present, our mines are underground and therefore we are able to make use of deep groundwater”. Clearly, they did not consider water as an issue/risk. But with the new guard focused on a groundwater crackdown and the possibility of more rain in the North, could China’s coal industry be in for a rude awakening?
Sure, more water in the North should be good for coal as 85% of China’s coal reserves lie in the North, but then 95% of China’s coal is mined underground and more rain in the North could lead to flooding of mines. Flood protection was something that the North did not have to worry about before. Again more spend.
According to a report published by CDP, “Metals & Mining: a sector under water pressure” in July 2013, the mining universe of 57 metals & mining companies surveyed, classified flooding as the #2 most important water risk currently, in the medium & long term.
The current #1 risk was declining water quality but in the medium to long term, water stress came out top.
Note that the 57 companies in the report did not include a single Chinese metals or mining company despite China’s water risk.
Past trends may not point to the future
In the face of changing weather and increasing water scarcity, reliance on past trends and experiences may longer work. With limited water resources, miners need to consider other users of water be it agriculture, industry or the community in the province.
“I see water security as being a major issue in the coming year. I think people are going to be somewhat blindsided by it … What’s happening in Peru should be a real wake-up call where water is a big driver in a lot of the problems that the extractive industries are having.”
Tom Burke, Environmental Policy Adviser to Rio Tinto
Companies and investors should look beyond the mining operations lest face the risk of being blindsided by social movements and government action like Newmont Mining: an expensive lesson that could have been avoided in hindsight.
Maybe it is time to heed Tom Burke, Environmental Policy Adviser to Rio Tinto’s warning “I see water security as being a major issue in the coming year. I think people are going to be somewhat blindsided by it … What’s happening in Peru should be a real wake-up call where water is a big driver in a lot of the problems that the extractive industries are having.”
Not factoring in water scarcity is not wise. In a hypothetical scenario of no access to water by 2030, HSBC estimated that this reduce Shenhua Energy’s valuation by 26%, China Coal’s by 45% and Huaneng Power’s by 30%. “In short, the issue is both substantial and urgent.”
More investment please
More investment in protecting water in mining seems inevitable if China was to continue to pursue energy security. With hydro running into tough weather, and commercial gas production a while away, there may be no other choice but coal. With the Chinese government seeming bent on improving industrial water efficiency, plus the fact that coal and coal-related industries account for over 50% of industrial water use, it makes sense to focus on the whole coal chain.
Don’t just take our word for it, check out the below graphic from Goldman Sachs’ China Growing Pains – Industry Position & ESG to define leadership report.
Margins will come under pressure and balance sheets will need to be shored up. The slowdown in the economy provides the sector a window of opportunity to hit “reset” in dealing with water. The question is where is this money going to come from?
