Is the end of coal in sight?

It came as no surprise that COP26 initially sparked bold statements on a rapid phase out of coal. The final text the phrase instead became “phase down coal”. Julian Kettle, Vice Chair of Metals and Mining looks at the challenge ahead in delivering on those commitments.

With the outcomes and implications of COP26 very much in the headlines, it’s worth highlighting one of the great paradoxes around the decarbonisation narrative. As my colleagues outlined very eloquently in their pre-COP26 briefing there are some dirty secrets that need sharing around coal. The uncomfortable truth is that while coal is an unwelcome guest at the decarbonisation table, we will still need coal-fired power to ensure an orderly transition to a low carbon world.

Coal is firmly in COP26’s sights

Coal, in all its forms, is always high on the decarbonisation agenda. But it is worth making a distinction between different types.

Most coal is burnt to produce electricity – thermal coal. However, a not insignificant volume is used as a reductant in the production of iron from iron ore, this type being known as metallurgical coal. While the two intersect both on the supply and the demand side (they are sometimes produced at the same mine and, at the margins, metallurgical coal can be used in power plants) there are two distinct markets.

To many of course ‘coal is coal’, and to an extent this is true, at least when viewing the impact on CO2 emissions. In this context one of the four key goals of COP26 – to “accelerate the phase out of coal” – is of course valid.

The COP26 statement is clear in intent, but short on detail

Coal was given plenty of attention at COP26. Most significantly, stakeholders from 52 nations, five sub nationals and 26 other organisations (mainly utilities) published a Global Coal to Clean Power Transition Statement. In summary, signatories committed to:

  1. Rapid scale-up of clean power generation and energy efficiency measures in their economies and support for other countries carrying out the same.
  2. Rapid scale-up of technologies and policies to achieve a transition away from unabated coal power generation in the 2030s (or as soon as possible thereafter) for major economies and in the 2040s (or as soon as possible thereafter) globally.
  3. Cease the issuance of new permits for new unabated coal-fired power generation projects (defined as projects that have not yet reached financial close), end new construction of unabated coal-fired power generation projects and end new direct government support for unabated international coal-fired power generation
  4. Strengthen domestic and international efforts to provide a robust framework of financial, technical, and social support to affected workers, sectors and communities to make a just and inclusive transition away from unabated coal power in a way that benefits them and expands access to clean energy for all.

These commitments sound impressive, however, what’s currently lacking is the detail of how they will be achieved. What’s more, this could be considered something of a Pyrrhic victory against coal, primarily because none of the countries with the top three largest coal-fired power fleets – China, India and the US – are signatories to the agreement.

Commitments by major players remain a work in progress

That’s not to say each of these coal behemoths have not made commitments.

China, which possesses the largest coal fired power plant capacity, has committed to peak carbon emissions, yet has made no firm commitment to reduce reliance on coal.

Meanwhile, in the US President Joe Biden’s plan for a zero-carbon grid by 2035 arguably embraces the spirit of the COP26 text. However, the devil is in the detail and there are not inconsiderable political challenges; not the least of these is the possibility of a significant reversal in policy should the next presidential election be won by the Republicans.

India was late to the decarbonisation pledge party but has committed to net neutrality by 2070. More urgently, it has pledged to reduce its projected carbon emissions by a billion tonnes by 2030. What’s more, India has committed to 50% renewables share of power generation and to reducing the carbon intensity of its economy by 45% by the same date. That’s a tough ask for an economy projected to grow by 6-7% a year over the next decade.

However, regardless of these targets, as we outlined in our pre-COP26 briefing ‘Coal: COP26’s dirty secret’, the inconvenient truth is that under our base case thermal coal demand will continue to rise until the mid-2020s. Fortunately, there is more than sufficient supply to meet that requirement.

Why not all coal is created equal

Of course, it’s not just about the volume of coal required but also the quality of coal that will be in demand and where it will be needed. To paraphrase George Orwell in Animal Farm, “all types of coal are created equal, but some are more equal than others.”

Increasingly, coal quality will be a differentiator with high-ranking coal favoured over low-ranking coal. Then there is the question of the location of the coal. The seaborne market for thermal coal is expected to be in deficit going forward, certainly under our base case scenario.

How will COP26 commitments impact coal demand?

Whilst the commitment to “phase down” coal is somewhat nebulous it is worth outlining what different temperature pathways would mean for thermal coal demand. Under our base case Energy Transition Outlook (ETO), which is aligned to a 2.7 °C warming TO scenario, demand for thermal coal will peak in 2025 at just over 7 billion tonnes, falling by just 5% to 6.7 billion tonnes in 2030, hardly a transformation! However, to achieve our AET-2, 2 °C pathway, demand for thermal coal will need to fall by a billion tonnes by 2030 and an AET-1.5 pathway removes a further 1.9bn tonnes of demand. This is a dramatic 2.4bn tonne reduction compared with the current base case peak in 2025. With COP26 renewing aspirations to align with Paris commitments to limit the average global temperature rise to 1.5°C the scale of the challenge of such a dramatic reduction of coal demand should not be underestimated given the implications for electricity supply in an increasingly electrified world.

The key question is, will the yet-to-be-enacted policies based on watered down commitments made at COP26 be enough to deliver an AET-2 or AET-1.5 decarbonisation pathway? If the non-delivery against commitments made at COP Paris in 2015 are anything to go by, success by 2030 looks to be a long shot and is by no means guaranteed. To paraphrase Mark Twain who upon hearing rumours that he had in fact died was quoted as saying “the reports of my death are greatly exaggerated”. I think the same can be said of coal!
