Singapore refiners weigh carbon tax pressure
As the first country in southeast Asia to introduce a carbon tax, industry and the wider region will be watching its next steps closely, writes Prethika Nair
Southeast Asian firms have gradually been gearing up for the energy transition, but the implementation of a significantly higher carbon tax in Singapore could impact the operations of refiners in the city-state sooner than expected.
Singapore last month announced plans to increase its carbon tax from 5 Singapore dollars/t ($3.70/t) currently to S$25/t in 2024-25 and S$45/t in 2026-27. The tax rate will be reviewed with a long-term view of raising it to S$50-80/t by 2030, finance minister Lawrence Wong says. This comes as part of the country's plan to bring forward its net zero carbon emissions target to around 2050 from the second half of this century, and signals a greater urgency for firms to decarbonise, in line with a global effort to reduce greenhouse gas (GHG) emissions.
The refining and petrochemical sector is a large source of carbon emissions in Singapore, with the industrial sector contributing about 45pc of total primary emissions, and the power sector contributing about 39pc, according to the National Climate Change Secretariat (NCCS) of Singapore. The carbon tax will impose a cost on the economy, but "we need to right-price carbon so that businesses will internalise the cost of carbon and invest in decarbonisation solutions", an NCCS spokesperson says.
The government aims to help companies with the transition by allocating part of the carbon tax revenue towards helping firms invest in low-carbon technologies. This step "is critical as the near-term competitiveness impact is real… [Singapore] has to compete with other exporter countries that either do not have a carbon price policy, or have sophisticated mechanisms to help their trade-exposed industries remain competitive, if they do", a Shell spokesperson says. "As Singapore has an open economy, it is also important that the designed carbon tax framework encourages GHG reductions, while safeguarding competitiveness of trade-exposed industries," ExxonMobil Asia-Pacific chairman Geraldine Chin says.
But refiners in Singapore appear ready to adapt. ExxonMobil has already undertaken initiatives to improve energy efficiency in its operations, such as operating three co-generation facilities that produce electricity and steam to support most of its plant operations. It is also looking into low-carbon solutions such as carbon capture and storage (CCS), often in collaboration with other firms in the region. Shell has reduced its crude processing capacity and production of traditional fuels by about half. The firm is studying biofuel investment and a regional CCS hub. Shell last month successfully delivered its first batch of sustainable aviation fuel in Singapore.
Credit problems
Singapore is the first country in southeast Asia to introduce a carbon tax, so its environmental outcome may set the tone for the rest of the region. Singapore's proposed taxof S$25/t ($18/t) is the highest in Asia — Japan's is equivalent to $2.65/t — but is still well below Sweden's $137/t, the highest in the world. Like Singapore, South Korea and China are also big exporters of refined products in Asia. China has seen rapid growth in refining capacity, although it has recently reduced exports. But China and South Korea have taken a different approach to reducing emissions, with the implementation of emissions trading schemes.
Carbon credits have been deemed potentially problematic as they allow the use of fossil fuels, and oil and gas firms' carbon offsets claims have been met with scepticism in the absence of industry-wide methodologies and certifications. But Singapore aims to "ensure that any credits procured are derived from genuine abatement, are internationally credible, aligned with global climate ambition, and in line with article 6 of the Paris agreement", the NCCS spokesperson says.

East-west marine biodiesel spread near six-month low
East-west marine biodiesel spread near six-month low
London, 6 September (Argus) — The east-west marine biodiesel spread narrowed amid firm demand for the B24 blend in Singapore and lacklustre spot marine biodiesel demand in northwest Europe in recent sessions. The east-west marine biodiesel spread — the premium held by B30 used cooking oil methyl ester (Ucome) dob ARA to B24 Ucome dob Singapore — was marked at $47.50/t on 5 September, its narrowest since 19 March. The spread narrowed amid a noted increase in demand from Asian-based shipowners who embark on voyages to Europe ahead of the implementation of FuelEU Maritime regulations in Europe next year — according to market participants. The latter had also reported an increase in B24 demand in Singapore from containerships seeking scope 3 emissions rights that can then be passed on to cargo owners. Scope 3 emissions rights can be obtained on a mass-balance system, allowing shipowners flexibility with regards to the port at which a blend can be bunkered. Argus assessed B24 dob Singapore prices at an average of $720.70/t on 1 July–5 September this year, compared with $757.70/t on 8 February–28 June following the launch of the B30 Ucome dob ARA price on 8 February. Consequently, the east-west marine biodiesel spread was marked at an average of $95.34/t on 1 July–5 September, compared with $74.57/t on 8 February–28 June. A wider east-west spread would incentivise shipowners to opt for the B24 blend in Singapore rather than ARA, when operationally viable, to meet the voluntary scope 3 demand from their customers. Rising demand in the Singapore bunkering hub was further supplemented by higher sales of marine biodiesel blends at the port. According to official data released by the Maritime and Port Authority of Singapore, sales of marine biodiesel blends in the second quarter of the year were marked at about 161,400t — higher by 34,500t from the previous quarter. This was also higher by 52,600t from the second quarter of last year. By Hussein Al-Khalisy Send comments and request more information at feedback@argusmedia.com Copyright © 2024. Argus Media group .

Singapore’s SP to launch 240MW solar project in China
Singapore’s SP to launch 240MW solar project in China
Singapore, 6 September (Argus) — Singapore's state-owned utility SP plans to start up a 240MW peak (MWp) agrivoltaic project in Guangdong province's Huizhou city, which will be fully operational by the end of this year. MWp refers to the maximum power output potential a solar farm has when reaching ideal conditions. SP expects the project to generate 7.5bn kWh of green electricity over the next 25 years, reduce coal use by 920,000t and avoid 4.46mn t/yr of carbon emissions. The project's solar installation capacity is 240MW, and marks SP's largest solar investment in China, the company said on 5 September. SP has secured 1.45GW of solar projects in China to date, spanning 18 provinces and municipalities. SP in May also partnered with China environmental technology solutions provider Qingdao Daneng Environmental Protection Equipment to invest and build a 90MW aquavoltaic farm in Qingdao city. This will power a green hydrogen facility in Qingdao, likely referring to Chinese refiner Sinopec's 4,500 t/yr facility . The solar project has an investment value of over 76mn Singapore dollars ($58.5mn) and is on track to connect to the grid by the end of the year. SP expects it to produce 162mn kWh/yr of green electricity and reduce carbon emissions by 160,000 t/yr. The operational model will incorporate renewable energy generation, grid integration, demand-side management, and energy storage. SP's first investment in solar assets was in June 2023, for 78MWp of agrivoltaics assets across four agricultural sites in the Dabu county of Meizhou city in Guangdong province. The project will generate 91.3GWh/yr of clean electricity, and reduce coal usage by almost 30,000t, which amounts to cutting more than 91,000 t/yr of carbon emissions. The operational date of this project was not disclosed. SP in May entered a strategic alliance with Shanghai-based CMB Financial Leasing to obtain financing services, which is expected to reach up to 8bn yuan ($1.13bn) over the next three years, to support the firm's deployment of renewable energy solutions in China. The projects will span utility-scale solar farms, distributed solar photovoltaic, energy storage, and district cooling and heating.

Pemex unbilled debts to suppliers climb
Pemex unbilled debts to suppliers climb
Mexico City, 5 September (Argus) — Service providers for Mexico's Pemex are unable to submit new invoices for services performed nearly a year ago even as the state-owned company also struggles to pay down past bills, sources say. These unsubmitted invoices do not appear in Pemex's financial records or in its monthly supplier debt reports, three Pemex suppliers who work mostly in the northern region of the Gulf of Mexico told Argus . Pemex provides vendors a system to submit bills for review and processing, leading to an invoice codifying payments and discounts (Copades). At this stage, Pemex certifies the pending invoice, making it part of the company's monthly supplier report —a transparency measure implemented in 2021. Pemex reduced its overdue debts to service providers by 6pc from May-July, with Ps126.4bn ($6.78bn) in unpaid invoices as of 31 July, down from Ps133.9bn in May. But a significant amount of unbilled work remains because Pemex has not issued the necessary Copades for vendors to begin the payment process, and some of the bills date back to work performed in September, according to two of the vendors. Without the Copades, companies must classify these debts as uncollectible, one vendor said. The issue is concentrated in Mexico's northeast maritime region, where Pemex produces about half of its crude and gas output, according to the vendors. This region includes the Cantarell and Ku-Maloob-Zap fields. Pemex has requested vendors to perform tasks in the area, but the company then claims there is no budget allocated for those bills, the vendors said. This unbilled work adds to Pemex's recognized debt to suppliers, but the size of this unrecognized debt is impossible to estimate, the vendors added. Pemex's unpaid invoices and short-term vendor debts stand at record-high levels, despite receiving over $70bn in government support since 2019.

Roadblocks across Colombia cut LPG supply
Roadblocks across Colombia cut LPG supply
Bogota, 5 September (Argus) — Colombia's LPG shortages are worsening as a fourth day of protests and roadblocks over higher diesel prices are limiting production and distribution. Protesters have completely blocked roads to processing plants in the key Cusiana and Cupiagua fields, preventing trucks from moving supply. Those two fields along with the Ty Gas processing plant handle 41pc of the country's LPG supply, LPG association (Agremgas) director Sara Velez told Argus . Colombia uses about 60,000 metric tonnes (t)/month of LPG. The Cusiana plant that produces about 15,000t/month of LPG is flaring 100t/d of LPG that cannot be transported, Velez said. "If Cusiana is unable to move out the LPG, it may force it to shut in, affecting natural gas as well," Velez said. Blockades are also preventing LPG produced at the 250,000 b/d Barrancabermeja and the 200,000 b/d Cartagena refineries from reaching distributors. The refineries produce 24pc of the country's LPG supply, equivalent to 14,400t/month. Adding to troubles, multiple rebel attacks have put sections of the country's 220,000 b/d Cano Limon-Covenas and the 120,000 b/d Bicentenario crude pipelines out of service for repairs, restricting crude supply to the refineries. The smaller LPG field of Capacho controlled by Canadian oil company Parex shut in 5,000 b/d of oil equivalent (boe/d), or about 10pc of its Colombian output. That reduced LPG supplies to the Arauca department, the LPG association added. The departments of Caqueta, Cundinamarca and Valle del Cauca have inventories for four days. Another 28 departments have LPG inventory for one or two days. Velez has called on the government to create a safe corridor to help LPG reach consumers. The LPG shortage is also affecting industries. Fenavi, the country's poultry association, consumes 42mn kg/yr of LPG, which is equivalent to state-controlled Ecopetrol's monthly LPG production. The LPG is used to warm the poultry, but the association also said that blockades have also cut supplies of feed and could put the chickens at risk of starvation. The country produces 1.8mn tonnes/yr of chickens and 1.6bn eggs/yr. In Colombia 1.2mn families already still cook with wood, and the current shortage will likely increase that number.
