One of many options of an upcoming COP is that the months prior usually carry with them a slew of proposals for brand new world targets and initiatives. This yr isn’t any completely different, maybe additionally pushed by the intense warmth and precipitation that has been difficult the Northern Hemisphere. In July, COP 28 President, Dr. Sultan al-Jaber, put ahead a proposed COP28 motion plan in a letter to the Parties. Together with various requires more and more speedy transformation and improved financing for creating nations, the plan contains the next three particular vitality system targets which have been additionally broadly reported on within the media:
The plan additionally contains emission discount targets for the oil and fuel business to attain by 2030 and features a name to rework heavy-emitting sectors, together with scaling up use of low-carbon hydrogen, carbon seize and storage, and carbon dioxide elimination, aligned with science. Nonetheless, no particular targets are included for these heavy-emitting sectors. This all represents fairly a formidable ambition, however to place these three vitality system targets into context the latest Shell Energy Security Scenarios present a helpful backdrop.
The eventualities comprise two completely different tales for the many years forward, however each are constructed from the security-focused world by which we presently discover ourselves. In Sky 2050, the troubles of the 2020s give solution to intense world competitors in a race to realize market share within the supply of fresh vitality techniques. Mutual curiosity prevails and net-zero emissions is achieved in 2050. However within the second state of affairs, Archipelagos, mistrust, self-interest and safety considerations prevail. Though a speedy transition takes place and emissions fall all through the century, the net-zero purpose isn’t realised till early within the 22nd century. Nonetheless, warming is restricted to 2.2°C above the 1850-1900 baseline interval.
The Vitality Safety Situations knowledge exhibits world renewable capability at round 3,500 GW in 2023, implying a 2030 purpose of round 10,000 GW. The 2023 capability is comprised of 1,200 GW hydroelectricity, 1,200 GW photo voltaic PV (industrial at 800 GW and rooftop at 400 GW) and 1,100 GW wind energy. There’s additionally 100 GW of business biomass burning, however not everybody considers this as renewable vitality. Whereas hydro and biomass present solely modest will increase over the rest of this decade, wind and photo voltaic enhance considerably in each eventualities. In 2023, photo voltaic PV seems to be growing by about 300 GW and wind by 100 GW, though a few of this can be associated to COVID delayed tasks now coming on-line. With seven full years earlier than the top of 2030, supply at these scales might imply some 3,300 GW of photo voltaic in whole and 1800 GW of wind in 2030, however that is nicely under the purpose of some 10,000 GW even with hydro and biomass included. The deployment charge must considerably enhance and that’s precisely what is going on in Sky 2050.
In Sky 2050 and Archipelagos, the expansion to 2035 is proven under.
In Sky 2050 the purpose is reached in 2030 however, in Archipelagos, it’s not till about 2035. This isn’t about completely different ranges of ambition throughout the eventualities, however as an alternative represents the very actual headwinds that speedy deployment might face, significantly within the circumstances of Archipelagos. Commerce disruption is a significant final result of the story, but there is a vital dependency on commerce inside the photo voltaic PV story. The minerals required, the manufacture of the panels, the grid enlargement (together with throughout borders) and even the labour required for set up all depend upon good buying and selling relationships and the free motion of individuals for work. For a purpose of 10,000+ GW, which could embrace 5,000 GW of photo voltaic PV, the present world manufacturing capability and set up functionality of round 300+ GW per yr must at the very least triple to round 1000 GW per yr, which suggests including 100 GW of latest manufacturing and set up functionality each yr between now and 2030. The venture pipeline for brand new manufacturing amenities seems strong, with the limitation on deployment in lots of areas being grid connectivity.
The second purpose is the need to double the typical world charge of vitality effectivity enhancements throughout sectors. That is fairly onerous to unpick with out additional particulars, but it surely actually doesn’t imply ‘doubling vitality effectivity’ as reported by some media retailers. The purpose might be in relation to the vitality depth of the worldwide financial system, which might be measured in vitality use per unit of GDP, or on the supply of vitality providers, i.e. a real effectivity measure, which might be in models comparable to tonne-km/MJ for highway freight. For this dialogue I’ll give attention to the previous.
In 2022 world vitality use was about 4.6 GJ per US$1000 (2016) GDP. This had improved from 5.64 GJ in 2010, which means an enchancment of some 20% or about 1.5% per yr. Presumably the ambition means shifting this to three% every year. If this have been the case then vitality use would fall to round 3.7 GJ per USS$1000 by 2030. Each Sky 2050 and Archipelagos are inside this vary, sitting respectively 0.1 GJ both facet in 2030. Aside from common societal enhancements in vitality effectivity, which have been ongoing for many years (9.5 GJ per US$1000 (2016) GDP again in 1960), the principle driver of change on this decade can be electrification of vitality providers. For instance, utilizing gasoline to energy a automotive has a well-to-wheel effectivity of about 25%, however utilizing electrical energy derived from photo voltaic or wind has a turbine-(or panel)-to-wheel effectivity of round 70% or extra (losses in transmission and storage of electrical energy mixed with the effectivity of the automobile itself). This COP28 purpose is a proxy for electrification, in all its kinds. Which means highway transport, residence cooking and heating and industrial use of electrical energy for warmth. It seems fairly doable, even within the slower Archipelagos transition.
Lastly there’s the purpose referring to hydrogen manufacturing, which appears very bold, however maybe this will depend on how it’s interpreted. The letter requires an general doubling of hydrogen manufacturing, with out a yr being given. The Monetary Occasions reported this as ‘Double hydrogen manufacturing to 180mn tonnes per yr by 2030’. This quantity pertains to the present world manufacturing of hydrogen which is about 90 million tonnes per yr, however most of this sits inside industrial processes such because the Haber course of to make ammonia. The Haber course of begins with pure fuel, and hydrogen is an intermediate product within the manufacturing. Most world hydrogen manufacturing immediately comes from pure fuel, releasing carbon dioxide as a part of the conversion course of. Some additionally comes from coal, with considerably elevated emissions in consequence.
Hydrogen can be produced as a remaining vitality product the place it’s then bought for different makes use of, comparable to in a gas cell to energy a truck or inside a subsequent industrial course of. That is the place the long run lies, with remaining vitality inexperienced hydrogen changing fuels comparable to diesel in vans, Jet A1 in planes and coal in iron ore smelting. These purposes quantity to a small manufacturing of ultimate vitality hydrogen immediately, maybe solely 100,000 tonnes every year. So doubling this quantity wouldn’t be bold in any respect and is sort of actually not what the letter is looking for.
If we use the present general world manufacturing of hydrogen and want to double that by 2030, then the COP28 goal would have the world at 180 million tonnes per yr (because the Monetary Occasions famous), which presumably means about 80 million tonnes for brand new remaining vitality purposes comparable to gas cells in transport and iron ore smelting. That is significantly in extra of even the Sky 2050 state of affairs, which sees 10 million tonnes in 2030 and doesn’t attain 80 million tonnes of ultimate vitality hydrogen till 2040. In Archipelagos that date strikes out to 2055.
The problem for hydrogen might not be the power to provide it, on condition that electrolyser manufacturing capability is ramping up in a short time. 80 million tonnes every year of inexperienced hydrogen would require some 600 GW of electrolyser capability to provide. In accordance with the IEA, world electrolyser manufacturing capability reached nearly 11 GW per yr in 2022, and based mostly on firm bulletins, the worldwide manufacturing capability for electrolysers might attain greater than 130 GW per yr by 2030. This might ship almost 400 GW of capability by 2030, nonetheless wanting the COP28 purpose however not markedly so. It’s additionally doable that important electrolyser capability might be launched to exchange the present steam reforming of pure fuel for ammonia manufacturing and this will surely cut back emissions; but it surely wouldn’t create new demand for hydrogen as required by the goal.
The actual concern for hydrogen as remaining vitality (or a hydrogen provider comparable to ammonia which is being checked out for ships) is creating that demand. There may be nearly none immediately. There are only a few vans that use hydrogen gas cells – no planes, no ships and nearly no industrial processes (aside from these the place it’s an intermediate product now). In pure gas-based direct discount ironmaking hydrogen does play a job, although that is together with carbon. Pure hydrogen isn’t presently utilized in ironmaking purposes aside from a handful of pilot crops. The ten million tonnes of latest hydrogen remaining vitality demand in Sky 2050 by 2030 is basically break up between business and highway freight. Delivery is barely simply rising in 2030 and aviation not till the 2040s.
Whereas the hydrogen purpose appears nearly misplaced in its ambition or maybe has merely been misinterpreted, the bundle of targets nonetheless represents an necessary step to attain by the top of this decade. However what’s puzzling is why the bundle didn’t embrace a particular goal for carbon seize and storage on condition that the UAE and Dr. Sultan al-Jaber have mentioned the significance of the know-how on many events. No matter the objections of some environmental teams, repeated analyses by a number of organisations (together with the Shell eventualities) present that with out carbon seize and storage know-how the 1.5°C purpose can’t be realised. We additionally shouldn’t neglect that whereas CCS tasks can take a couple of years to ship, their scale is important at 1+ million tonnes CO2 per yr per venture as soon as operational.
A considerable however not unachievable purpose for 2030 can be to see the development of 500 giant scale (> 1 million tonnes every year CO2) CCS amenities. As of late 2022, the World Carbon Seize and Storage Institute reported 30 amenities in operation, 11 beneath building and about 150 in numerous phases of planning.
