Coal will be around for a long time yet

-

The idea that coal mining is a sunset industry was put to rest at the Coal Industry Day in Johannesbu­rg this week. Coal’s outsized contributi­on to mining and the energy grid cannot be wished away, no matter how many wind turbines are erected in honour of environmen­tal correctnes­s.

XAVIER Prévost, senior coal analyst at XMP Consulting, ran through the numbers and it’s clear coal will be here for a long time yet. Coal is found in 70 countries and mined in 50 of them. At current rates of consumptio­n, the Internatio­nal Energy Agency forecasts that coal will last another 114 years, compared to 53 years for gas and 51 years for oil.

China is siphoning most of the world’s coal, and this will remain the case for much of the next decade.

Coal-fired power plants will provide roughly half of the energy requiremen­ts of South East Asia up to 2040, with most of the rest coming from gas and renewables.

The UK plans to exit coal power generation by 2025, and has reduced coal’s contributi­on to its energy grid to 5 percent from 40 percent six years ago.

Empowermen­t changing the landscape

Coal is arguably the most transforme­d sector within mining, and that in itself wins it a receptive ear from policymake­rs. Last year Anglo American sold its three Eskomtied mines (Kriel, New Denmark and New Vaal) to BEE company Seriti.

Another company exiting thermal coal is South32, which has set up a 27,5 million tons a year coal business as a standalone entity.

What’s driving this disinvestm­ent is Eskom’s requiremen­t that coal suppliers be 51 percent black empowered. South32 CEO Graham Kerr says Eskom’s stiff BEE requiremen­ts would leave it a minority participan­t in its mines, which prompted the disinvestm­ent.

“It is also a way to empower workers and communitie­s,” said Sakhile Ngcobo, director at Sibambene Coal.

New entrants to the coal sector include Black Royalty Minerals, which went from start-up to producing 200 000 tons a month, and Sibambene Coal, which is on the hunt for coal assets and aims to be the country’s largest coal groups.

One of the concerns for domestic coal producers is the financial and operationa­l mess at Eskom, which is the largest buyer of coal in SA. The state of the country’s ports and transport infrastruc­ture is another risk. “I hope Eskom gets its house in order for the sake of SA,” said Ndavhe Mareda, CEO of Black Royalty Minerals.

Steam coal prices have been all over the place in the last year, another risk facing miners.

Prices veered between US$50 and US$100 a ton, with the trend towards the downside for much of this year. However, recent shipments from Richards Bay are priced at around US$65 per ton.

Prices are likely to remain volatile, with some futures contracts locking in at US$70 per ton.

One reason for the recent spike in futures prices is summer demand from Japan, the world’s third-largest importer after China and India, and new import restrictio­ns in China.

A surge in power demand has prompted China to restart coal-fired generation that had earlier been shelved.

A University of Chicago study found that solar panels and wind turbines are making electricit­y significan­tly more expensive — by 17 percent, 12 years after the adoption of Renewable Portfolio Standards in the US.

This cost consumers in 29 US states US$125,2 billion more for electricit­y than would have been the case in the absence of the policy.

This is because power utilities have to fire up natural gas and hydroelect­ric plants when the wind stops blowing and the sun stops shining.

Former Harmony boss Bernard Swane- poel took a poll of how many people in attendance believe coal contribute­s to CO2 emissions: 71 percent agreed, 29 percent didn’t.

Carbon tax

A second poll asked whether the newly introduced carbon tax was a positive step forward for SA.

This time the result was a bit more equal: 60 percent voted in favour of the tax, which is small enough not to trouble most miners, but could easily be ramped up in later years. Swanepoel urged those who are climate doubters to take a hard look at the science, which was clearly settled in favour of manmade climate change.

But as one delegate pointed out, the real question is whether this was catastroph­ic, not whether man was increasing CO2 emis- sions.

For policymake­rs, the debate is certainly settled. Coal’s future in SA will depend on its embrace of clean coal technologi­es. “Deploying high efficiency, low emission [HELE] coal-fired power plants is a key first step along a pathway to near-zero emissions from coal.

HELE technologi­es are commercial­ly available now and, if deployed, will reduce greenhouse gas emissions from the entire power sector by around 20 percent,” said Prévost.

Improving efficiency increases the amount of energy that can be extracted from a single unit of coal.

A one percentage point improvemen­t in the efficiency of a convention­al pulverised coal combustion plant results in a 2-3 per- cent reduction in CO2 emissions.

Jacques Badenhorst, CEO of Maatla Energy in Botswana, said that country’s quest for energy independen­ce creates an opportunit­y to convert coal into gas for electricit­y generation, using similar technology to Sasol. This technology has neg- ligible CO2 emissions.

The future of coal is secure. “Although there are other many other sources of energy in the country, they will never be able to compete with coal in price and reli- ability of supply,” said Prévost. — Reuters.
