Bunker biofuel pilot projects launch in Asia
The marine industry has shifted its attention to accommodating the International Maritime Organisation's (IMO) greenhouse gas (GHG) strategy, after having to adjust to the Covid-19 pandemic and the implementation of the IMO's global sulphur cap in marine fuels.
The IMO's goals consist of reducing carbon emissions in the maritime sector by 40pc by 2030 and by at least 50pc by 2050 from 2008 levels.
Biofuels, such as biodiesel and ethanol, are another type of alternative shipping fuel that could meet the IMO's decarbonisation goals. They emit negligible sulphur and carbon emissions, while they can easily be blended with conventional bunker fuels.
Several large container shipping lines are carrying out pilot studies to produce second generation biofuels. Danish shipping firm Maersk launched last year a type of biodiesel derived from used cooking oil (UCO). French shipping firm CMA CGM has a partnership with Shell to supply some of its fleet with a similar fuel, which is a blend of 80pc very-low sulphur fuel oil (VLSFO) and 20pc biofuel made of UCO.
But the handling of fuels derived from biomass is largely unfamiliar to shipowners and questions remain especially regarding scalability and availability. Some biofuels can also not be considered "drop-in" fuels as existing vessels' engines will need to be modified extensively to be able to use them, which means they are typically only considered as a viable alternative for newbuilds.
Biofuels are more expensive than conventional fuels and so depend on governmental incentives and levies on carbon fuels to compete on price. Such support frameworks mainly exist in Europe and North America but remain largely absent in Asia.
The Maritime and Port Authority of Singapore in 2017 supported a letter of intent between UK-Australian mining company BHP and Dutch biofuels producer GoodFuels to support a biofuels pilot project. Singapore shipowner Eastern Pacific Shipping on 15 October this year appointed GoodFuels to supply one of its Medium Range tankers with biofuel bunkers.
A group of South Korean companies including Hyundai, Korea Bio Energy, Korea Shipbuilding and others, signed an initial deal in August this year to promote the adoption of bio heavy oil in shipping, produced from animal and plant oil and residues from biodiesel production.
South Korea's SK Chemicals has also said it will look into increasing its biofuel output by 50pc to accommodate rising demand for biofuels from the shipping sector. The company already created blends of biodiesel with conventional fuels to produce low-sulphur fuel oil to meet the IMO's 2020 0.5pc sulphur cap in marine fuels that took effect on 1 January this.
Japanese shipping firm Mitsui OSK Lines in December this year carried out a biodiesel trial on one of its tugboats at the port of Nagoya. The fuel is a blend of UCO and algae derivative from biotechnology venture company Euglena. GoodFuels last year delivered biofuels on board a bulk carrier owned by Japanese shipping firm NYK.
China, one of the world's largest biofuel and ethanol producers, has yet to consider renewable fuels as part of its low-carbon shipping strategy as it remains focused for now on boosting its VLSFO output.

California refineries required to report turnarounds
California refineries required to report turnarounds
Houston, 10 May (Argus) — Refiners in California starting in June must file maintenance schedules with the state's energy commission at least 120 days in advance of planned work, and diagnostic reports within two days of unplanned shutdowns. The new reporting requirements, part of the SB X1-2 bill passed in March 2023, take effect following an 8 May meeting of the California Energy Commission (CEC) where the measures were finalized. The CEC will now be able to gather a broad range of data from refiners and set a maximum gross gasoline refining margin in an effort to avoid price spikes at the pump. If companies identify a need for maintenance less than 120 days before the planned work, a report to the CEC is required within two business days of the discovery, according to the reporting form posted in the SB X1-2 docket. The reporting form includes space for a description of the work, unit level details and information on the expected effect of a turnaround on transportation fuel inventories at the refinery. The same information will be required for unplanned maintenance, with a report to be sent to the CEC within two business days of the initial outage or lowered rates, and within two business days of the completion of work or return to normal throughputs. The additional information will aide the CEC in analyzing refiner margins and determine whether a margin cap and subsequent penalties are warranted, according to the commission. Industry groups think many of the reporting requirements are burdensome and politically motivated , often requesting information unnecessary to determine margins. Marine import reporting on horizon At the same 8 May business meeting, the CEC moved closer to finalizing a requirement for importers of foreign and domestic refined products and renewable fuels to report shipments at least four days before delivery. The reporting form includes information on vessel routes, costs and products shipped. The CEC approved for the marine reporting requirements to be submitted to the state's Office of Administrative Law for a 10-day review before a targeted 20 May start date. By tracking import data, the CEC aims to build a more accurate picture of what drives retail fuel prices and refiner margins in the state. "In many cases these forms request information that has questionable or no relevance at all to the CEC's efforts to minimize or prevent price spikes," said Sophie Ellinghouse, general counsel for trade group the Western States Petroleum Association, during public comments on the marine reporting requirements at the 8 May meeting.

Brazil narrows lower biofuel mix mandate in south
Brazil narrows lower biofuel mix mandate in south
Sao Paulo, 10 May (Argus) — Brazil's oil regulator ANP dialed back the reduced biofuels mandatory blend in Rio Grande do Sul state to four cities amid the recent flooding in the region. Low blending areas now apply only to the cities of Canoas, Esteio, Rio Grande and Santa Maria. The measure will still last for 30 days, starting on 4 May. ANP lowered the anhydrous ethanol blend on gasoline to 21pc from the current 27pc in the entire state earlier this week , while pushing the mandatory biodiesel mix for 10ppm (S10) diesel down to 2pc, from the usual 14pc. The agency also temporarily suspended the blending mandate for diesel with 500ppm of sulfur (S500). ANP said it decreased the exemption's coverage as it identified "that the supply situation in the rest of the state had stabilized." Rainfall in Rio Grande do Sul blocked railways and highways where biofuels are transported to retail hubs. Floods in the state have left at least 116 dead and 143 missing, according to the local government.

Mexican power outages enter fourth day
Mexican power outages enter fourth day
Mexico City, 10 May (Argus) — Mexican power grid operator Cenace issued its fourth consecutive day of operating alerts amid the heatwave gripping the country. Net electricity demand reached 47,321MW early today, with deployed electricity capacity slightly below at 47,233 MW, according to Cenace. Since 7 May, Cenace has declared emergency operating alerts as demand exceeded generation capacity during peak evening hours, prompting the grid operator to preemptively cut electricity supply across different states to maintain grid integrity. Power outages have lasted up to several hours in Mexico City and in major industrial states as power demand has outstripped supply by up to 1,000MW. Peak demand this week hit 49,000MW, just below last year's historic peak of 53,000MW during atypical temperatures in June. "We are very concerned about the unprecedented outages detected across 21 states, a situation that affects the normal functioning of Mexican companies," national business chamber Coparmex said. Peak electricity demand typically rises in June-July but temperatures this week have risen as high as 48°C (118° F) across some states. Mexico City reported a record high of 34.3°C on 9 May and high temperatures are forecast to continue into next week, Mexico's national weather service said. The inability of Mexico's grid to respond to increased demand is because of insufficient power generation capacity, non-profit think-tank the Mexican institute for competitiveness (Imco) said this week. "Despite the energy ministry's forecast that 22,000MW of new power capacity would enter service by 2026, only 1,483MW had entered service as of 2022" since late 2018, Imco said. President Andres Manuel Lopez Obrador's administration pledged to build new generation capacity, including five gas-fired, combined-cycle plants, but recognized this week that delays had contributed to the power outages. "We have an electricity generation deficit because some of the combined-cycle plants were delayed, but we are working on it and it will soon be resolved," Lopez Obrador said on 9 May. Lopez Obrador's government has also curtailed private sector power development during his administration. Mexico needs to upgrade and expand its transmission network, industry associations say. "In order to resolve this problem, we believe that a reopening of the electricity market to the private sector is imperative," Mexico's wind energy association, Amdee, said. Mexico has 87,130MW of installed capacity, with 39.5pc from combined-cycle gas-fired power plants and 31pc in renewable power, including wind, solar, hydroelectric, geothermal and biomass, according to the latest statistics from the energy ministry.

Brazil reports more off-spec biodiesel March-April
Brazil reports more off-spec biodiesel March-April
Sao Paulo, 10 May (Argus) — The rate of Brazilian biodiesel falling below required blending limits nearly tripled in March and April after the mandate was increased to 14pc, according to a government analysis. Hydrocarbons regulator ANP's Fuel Quality Monitoring Program (PMQC) found 271 instances of biodiesel below the required level between 1 March — when the blending mandate was increased from 12pc to 14pc — and 30 April. In January and February the PMQC found 97 instances of blends that did not meet the 12pc level. An increase in missed blending targets is common during transitions to higher blending levels, according to the agency, mainly due to difficulties in depleting inventories of the lower-level blend. Several plants claim that a slowdown in biodiesel withdrawals in the first four months of the year also contributed to challenges in complying with the new blending level. Some retailers' loss of market share has also been cited as an aggravating factor. In March, 154 recorded instances of non-compliance covered blending levels between 12.3pc and 13.9pc, according to ANP data. In April, there were 101 occurrences within the 12.3pc and 13.9pc range. Another eight instances of non-compliance were also recorded in each of March and April. The PMQC is a monitoring program and does not have the same effect on market behavior as inspections, according to ANP. "It is used as one of the intelligence vectors for the planning of ANP's inspection actions," the agency said. Only irregularities identified in the context of inspectios can result in fines levied against fuel distributors.
