Asia maritime decarbonisation faces fuel dilemma: Panel
Alternative fuels are the way to go to decarbonise the maritime industry, but the various fuel options create uncertainty and the risk of stranded assets for ports like Singapore's Jurong Port, according to panellists at a maritime seminar on 29 November.
Alternative fuels available to the maritime industry range from biofuels to methanol to ammonia and liquid hydrogen, each with their respective pros and cons. This creates a risk for port operators when they choose what fuel infrastructure to invest in, Singapore port operator Jurong Port's chief technical officer and chief sustainability officer Tan Wee Ming said at the Maritime Energy and Sustainable Development Centre of Excellence (MESD) seminar in Singapore. Singapore is the world's largest bunkering hub.
Tan added that should ports wait to observe the market direction, they would not only have to wait for engine manufacturers to give the go-ahead, but also for vessel owners to trial such engines, test the vessels in water, among other logistical issues, before ports are able to start building infrastructure. By then, the response time to do so is very short, Tan said, which adds to the challenges that ports face.
Fuel uncertainty is also complicating decision-making at marine services firms. "Not all types of alternative fuels will be applicable across the board," Singapore marine services provider PSA Marine's head of fleet management Bernard Wong said at the seminar on 29 November. "There will be a need to differentiate," he added, referring to a need to cater to flexibility and options within the industry.
Singapore-based business unit Rolls-Royce Solutions Asia's Asia-Pacific director of sales marine and offshore Chew Xiang Yu agreed. "Where are we going to invest our resources to?" he asked, referring to the breadth of alternative fuels available. He also added that development projects need to run for many years to come, as assets or engines are being developed to operate for 10-15 years and not shorter durations like five years.
But when it comes to selecting which fuels to focus on, especially given that Singapore has little available space to adopt different green fuels, Wong is of the opinion that the key question is about "what is most practical", referring to safety standards and the ease of bunkering. He also added that the business aspect still remains pertinent when it comes to answering who will pay the premium if there is indeed one.
But Tan said it is important to "find a way to lock it in" and prove that Singapore is able to handle these alternative fuels, even if some of them are potentially dangerous. He also noted the importance of a "strong leadership" to foster collaboration. There could be many unknowns when undertaking new studies, but giving up on a promising idea in favour of one that is sub-par because of high costs is "not doing justice to the collaboration", Tan said.

G7 countries put timeframe on 'unabated' coal phase-out
G7 countries put timeframe on 'unabated' coal phase-out
London, 30 April (Argus) — G7 countries today committed to phasing out "unabated coal power generation" by 2035 — putting a timeframe on a coal phase-out for the first time. The communique, from a meeting of G7 climate, energy and environment ministers in Turin, northern Italy, represents "an historic agreement" on coal, Canadian environment minister Steven Guilbeault said. Although most G7 nations have set a deadline for phasing out coal-fired power, the agreement marks a step forward for Japan in particular, which had previously not made the commitment, and is a "milestone moment", senior policy advisor at think-tank E3G Katrine Petersen said. The G7 countries are Italy — this year's host — Canada, France, Germany, Japan, the UK and the US. The EU is a non-enumerated member. But the pledge contains a caveat in its reference to "unabated" coal-fired power — suggesting that abatement technologies such as carbon capture and storage could justify its use, while some of the wording around a deadline is less clear. The communique sets a timeframe of "the first half of [the] 2030s or in a timeline consistent with keeping a limit of 1.5°C temperature rise within reach, in line with countries' net-zero pathways". OECD countries should end coal use by 2030 and the rest of the world by 2040, in order to align with the global warming limit of 1.5°C above pre-industrial levels set out in the Paris Agreement, according to research institute Climate Analytics. The countries welcomed the outcomes of the UN Cop 28 climate summit , pledging to "accelerate the phase out of unabated fossil fuels so as to achieve net zero in energy systems by 2050". It backed the Cop 28 goal to triple renewable energy capacity by 2030 and added support for a global target for energy storage in the power sector of 1.5TW by 2030. The group committed to submit climate plans — known as nationally determined contributions (NDCs) — with "the highest possible ambition" from late this year or in early 2025. And it also called on the IEA to "provide recommendations" next year on how to implement a transition away from fossil fuels. The G7 also reiterated its commitment to a "fully or predominantly decarbonised power sector by 2035" — first made in May 2022 and highlighted roles for carbon management, carbon markets, hydrogen and biofuels. Simon Stiell, head of UN climate body the UNFCCC, urged the G7 and G20 countries to lead on climate action, in a recent speech . The group noted in today's outcome that "further actions from all countries, especially major economies, are required". The communique broadly reaffirmed existing positions on climate finance, although any concrete steps are not likely to be taken ahead of Cop 29 in November. The group underlined its pledge to end "inefficient fossil fuel subsidies" by 2025 or earlier, but added a new promise to "promote a common definition" of the term, which is likely to increase countries' accountability. The group will report on its progress towards ending those subsidies next year, it added. Fostering energy security The communique placed a strong focus on the need for "diverse, resilient, and responsible energy technology supply chains, including manufacturing and critical minerals". It noted the important of "guarding against possible weaponisation of economic dependencies on critical minerals and critical raw materials" — many of which are mined and processed outside the G7 group. Energy security held sway on the group's take on natural gas. It reiterated its stance that gas investments "can be appropriate… if implemented in a manner consistent with our climate objectives" and noted that increased LNG deliveries could play a key role.

UN eyes policy crediting for carbon markets
UN eyes policy crediting for carbon markets
Berlin, 30 April (Argus) — The UN is considering extending the scope of carbon mitigation credit generation under the Paris climate agreement to policy implementation. The UN's climate arm has tasked research institute Perspectives Climate Group senior founding partner Axel Michaelowa with drawing up a paper on how to incorporate policy crediting into the new carbon market being developed under Article 6.4 of the Paris deal. This is expected to be finalised by the UN Cop 29 climate conference in Azerbaijan in November following persistent disagreements between countries at previous summits. Policy crediting is increasingly viewed as crucial amid the rising urgency to scale up mitigation activities, Michaelowa said at an industry event in Zurich yesterday. But policy crediting presents challenges, such as how to determine the additionality of the instruments for mitigation efforts. The World Bank, which developed the first ever policy crediting activity — the Transformative Carbon Asset Facility — in 2016, determines additionality indirectly as the difference between the facility's baseline and actual emissions. Michaelowa believes this is insufficient, urging separate additionality tests to prove the policy instrument mobilises mitigation. An eligible policy instrument typically closes the cost gap between mitigation and business-as-usual technologies, Michaelowa said. "Creditable" policy instruments are mandates, or financial incentives, for deploying low-carbon technologies or behaviours. Policies that reverse previous bad governance by eliminating obstacles to mitigation activities also qualify, Michaelowa said, for example a grid operator enforcing a stop on renewable power growth to ensure grid stability, as investments in the grid would be too costly. Uzbekistan signed an agreement under the World Bank's facility in June 2023 under which it can sell carbon credits issued for the emissions reductions resulting from its cuts to high fossil fuel subsidies. The resulting funds are used to mitigate the impact of rising energy prices on the lowest income consumers, and fund awareness campaigns on the need for cost-covering energy tariffs. Uzbekistan expects to reduce its emissions by 60mn t of CO2 equivalent (CO2e) between 2022-27 as a result of the cuts, of which 2mn-2.5mn t CO2e are attributed directly to the facility's intervention, funded with $46.25mn by donor countries to result in a carbon price of between $18.50-23.12/t CO2e. The World Bank is looking at other countries and sectors to apply the lessons learned from the Uzbekistan pilot, its senior climate finance specialist Nuyi Tao said.

Higher C919 adoption to boost China's Ti demand
Higher C919 adoption to boost China's Ti demand
Beijing, 30 April (Argus) — Higher adoption of the C919 airliner, China's first self-developed single-aisle passenger jet, is likely to boost demand for titanium mill products in the coming years, according to market participants. China Southern Airlines, one of the country's top three airlines, ordered 100 C919 aircraft from its manufacturer Commercial Aircraft Corporation of China (Comac) yesterday. These aircraft will be delivered in 2024-2031. China's flag carrier Air China on 26 April also announced that it will purchase 100 C919 aircraft from Comac during the same period. Another major airline, China Eastern Airlines, in September 2023 placed an order for 100 C919 aircraft from Comac, which delivered the fifth unit this March. This means all three top China airlines have invested in 100 aircraft deals for C919. Market participants estimate a single C919 aircraft contains 3.92t of titanium mill products. Demand for titanium mill products from a single C919 aircraft will reach 49t based on an overall yield rate of 8pc for mill products used in aviation parts. Titanium mill products typically include titanium strip, rod, section bar, wire, plate, sheet, tap and foil. Comac launched the C919 development programme in 2008 and began prototype production in 2011. The airliner had its maiden flight in 2017 and received its airworthiness certification from Chinese authorities in September 2022. A continued increase in orders and deliveries of the C919 airliner is likely to continue to boost demand for titanium mill products in the coming years. Comac has received over 1,400 orders for C919 from domestic and international airlines so far. China's 32 major manufacturers produced 159,000t of titanium mill products in 2023, up by 5.3pc from 151,000t in 2022, according to statistics from China nonferrous metals industry association titanium zirconium and hafnium branch (CNIA-TI). Aerospace, the second-largest consumption industry for titanium mill products, consumed 29,377t of titanium mill products in 2023, accounting for 19.8pc of China's total domestic production. "Demand from the aerospace industry has large potential in China," a source at a Baoji-based mill products manufacturer told Argus . "Only 20pc of titanium mill products is used in China's aerospace industry now, while the proportion is as high as 70-80pc in Europe and the US." A number of titanium mill products manufacturers in Baoji, which is known as China's "titanium valley", have begun to supply Comac as they have improved their product quality to meet Comac's criterion. Comac designated the country's largest producer Baoji Titanium (BaoTi) as the sole supplier of titanium mill products for the airliner just last year. Argus -assessed prices for titanium ingot, the main feedstock in the production of mill products, held stable from 23 April at 60,000-62,000 yuan/t ex-works for TA2 grade today, in response to firm titanium sponge feedstock costs and steady demand from mill products manufacturers.

Gas-fired units win Japan's clean power auction
Gas-fired units win Japan's clean power auction
Osaka, 30 April (Argus) — A planned 10 gas-fired generation units have won Japan's first long-term zero emissions power capacity auction, with the awarded capacity totalling nearly 6GW, or auction volumes sought for the first three years of the programme. Japan launched the clean power auction system from the April 2023-March 2024 fiscal year, aiming to spur investment in clean power sources by securing funding in advance to drive the country's decarbonisation towards 2050. The auction generally targets clean power sources — such as renewables, nuclear, storage battery, biomass, hydrogen and ammonia. But the scheme also applies to a new power plants burning regasified LNG as an immediate measure to ensure stable power supplies, subject to a gradual switch from gas to cleaner energy sources. The first auction held in January saw 10 new gas-fired units with a combined capacity of 5.76GW secure the funding of ¥176.6bn/yr ($1.12bn), the nationwide transmission system operator Organisation for Cross-regional Co-ordination of Transmission Operator (Occto), which manages the auction, said on 26 April. All winners can receive the money for 20 years through Occto, which collect money from the country's power retailers, although they need to refund 90pc of other revenue. Winners with a new gas-fired project should start commissioning their plants within six years and then begin refurbishment work to introduce clean fuels and technology within 10 years after commissioning. This means all the projects selected in the 2023-24 auction need to start operations by the end of 2030-31. Hokkaido Electric Power previously planned to begin operations of its Ishikariwan-Shinko No.2 gas-fired unit in December 2034 but it has advanced the start-up to 2030-31. Japan has secured a total of 9.77GW net zero capacity through the 2023-24 auction. Contract volumes include 1.3GW of nuclear, 1.1GW of storage batteries, 770MW for ammonia co-firing, 55.3MW hydrogen co-firing, 199MW biomass and 577MW of hydroelectric power projects, along with the 5.76GW of gas-fired projects.
