Viewpoint: Sustainable jet fuel poised for growth

  • : Biofuels, Emissions, Oil products
  • 19/12/31

Government incentives and higher blending mandates will boost sustainable aviation fuel (SAF) production in the coming year, but greater support for renewable diesel may temper that growth.

SAF is a jet fuel sourced from non-petroleum feedstocks, such as waste oils, wood fiber or algae. Both California's Low-Carbon Fuel Standard (LCFS) and Oregon's Clean Fuels Program added alternative jet fuel as an eligible credit generator at the start of 2019.

With California LCFS credit prices near record program highs and the Oregon LCFS prices seeing more subdued gains, market participants see those programs as strong incentives for SAF growth.

But growth will not be as sharp as it otherwise could be because of producers' pull toward renewable diesel. Renewable diesel is often co-produced with SAF in the same refining process, which forces companies to make a decision about which fuel to produce. To date, the economics have largely favored renewable diesel. In 2019, alternative jet fuel producers have to best a carbon intensity (CI) score of 89.37g CO2/megajoule to generate LCFS credits, while alternatives to diesel have to beat a CI score of 94.17g. This is one reason renewable diesel production is still more attractive than SAF production, which will still be the case for the next few years.

Another bearish factor for SAF is the California Air Resources Board's (ARB) new cap on the price in the secondary market at the same price used for the LCFS program's credit clearance market — $200/t in 2016 dollars, adjusted for inflation. That price in 2019 is just over $213/t. Most renewable fuels projects have been profitable at current, and even lower, LCFS credit prices, so there is no immediate reason for growth to slow down for renewable diesel, biodiesel, or renewable natural gas.

But the ARB's decision may put at risk the next-generation technologies that are not yet commercialized on a large scale, including sustainable aviation fuel. The additional credit generators that have recently been added to the LCFS, and others that could be, might need extra investment for those projects to come to fruition.

This all puts the onus on airlines or intermediaries to pay a premium if they want to secure SAF. Although the premium of this fuel over conventional jet fuel is likely to narrow over the next decade with the further maturation of technologies and as more planned supply comes on line, it is unlikely the two fuels will reach price parity in the near term.

But other biofuel blending mandates for aviation and clean fuels programs are on the horizon, which will support growth of SAF, increase overall supply in the market, and help narrow that price premium.

Canada's proposed clean fuel standard has an aviation component, as does the program being developed by the Puget Sound Clean Air Agency, a regulator for the Seattle, Washington, region. British Columbia will soon add alternative jet fuel as a credit generator to its LCFS. And the fact that Nordic countries are implementing mandates to procure renewable jet fuel is encouraging and will grow this market, biofuels producers have said.

Norway has already passed legislation to introduce a blending requirement of 0.5pc of biojet for its aviation industry from 2020, while the Finnish government has approved a quota to achieve 30pc biofuels penetration in aviation by 2030. Sweden's government has proposed a greenhouse gas emissions-reduction obligation for jet fuel used in Sweden from 2021.

Decarbonization goals are gaining more attention in the global airline industry, the "flight shaming movement" is becoming more widespread in Scandinavia, and carriers are starting to mull compliance options for UN aviation agency Icao's planned carbon offsetting scheme for global aviation emissions, all of which will help support SAF's growth.

Environmental markets wary of Trump's next moves

Environmental markets wary of Trump's next moves

Houston, 28 April (Argus) — US President Donald Trump's recent threat of legal challenges against state climate and clean energy policies has roiled environmental markets waiting to learn the scope and avenues those confrontations could take. Trump's 8 April executive order, which directed the Department of Justice (DOJ) to consider contesting state policies that threaten "American energy dominance", targeted California's cap-and-trade program by name, but it may also extend to other policies, including renewable portfolio standards (RPS). But uncertainty about the extent of the administration's ambitions has injected another variable into an already volatile economic landscape. Market anxieties may not fade soon. US attorney general Pam Bondi has until early June to report on actions she has taken and make recommendations for other steps by the White House or Congress. Conservatives in some states already have asked her to scrutinize particular programs. Administration arguments One angle from which the DOJ could attack state programs is the well-trod "dormant Commerce Clause", a legal doctrine that says state laws cannot discriminate against or impose undue burdens on another state's economic activity. But such a challenge is more difficult if a program is merely stipulating, "if you want to come to our state, our electricity market or our fuel market, here are the rules to play by", according to Matthew Dobbins, a partner at Vinson & Elkins and member of the law firm's environment and natural resources team in Houston. Courts have dismissed lawsuits that tried this approach against low-carbon fuel standards in California and Oregon , as well Colorado's RPS. In addition, an appeals court last year threw out a case against Washington's cap-and-invest program, ruling it did not overstep in its handling of in-state versus out-of-state electricity suppliers. The US Supreme Court may soon decide whether to hear an appeal of the case. More broadly, a 2023 Supreme Court decision upholding a California law restricting interstate pork sales based on animal treatment makes such dormant Commerce Clause challenges "a lot harder", according to Nico van Aelstyn, partner at Sheppard Mullin in San Francisco. The DOJ could try using the "Equal Sovereignty" doctrine, which stipulates that one state's rights cannot exceed another's, van Aelstyn said. This has been used in cases against California's vehicle emissions standards and other states' climate "superfund" laws, which penalize oil and gas companies for historical emissions. But van Aelstyn described it as "not really tested yet." That administration has also been hoping to fast-track Supreme Court rulings on the executive orders by justifying them through "declared emergencies," according to Dobbins. This use of emergency powers will likely reveal how far the court will go to "pressure test" the administration's requests for speedy judicial relief, as justices work through a growing emergency docket through the end of term in June or July. Relitigating the past Amid growing trade tensions between the US and Canada, the DOJ could also revive a 2019 lawsuit against California's cap-and-trade program. A US district court at the time ruled that federal purview over foreign affairs does not preempt the state linking its program with Quebec's. Although the first Trump administration appealed the ruling, former president Joe Biden withdrew the case, leaving the matter undecided with one claim potentially still ripe for judicial review. "What that'll probably come down to is how much Canada has expressed its anger . . . and if the administration is willing to go 'all in' on trying to provoke one of our largest trading partners," Dobbins said. But even if California severed ties with Quebec, the province is a small part of the market, and its absence is unlikely to cripple the state's program. Meanwhile, in the markets… Trump's executive order has put states and US companies alike on the back foot, adding to a "shock and awe" barrage from tariffs and potential rollbacks to federal clean electricity incentives , said Tom Harper, a partner on consultant Baringa's energy advisory team in New York City. That volatility has led clean energy developers and buyers to hold off on decisions until they have a bit more stability. "You're almost in a state of paralysis because you can't go and deploy a team on a project. You can't go and arrange finance because the cost is moving day to day," Harper said. The tariffs have also fed growing concerns about the US economy, which have spilled into environmental markets. The California Carbon Allowance (CCA) market, already a bit bearish because of ongoing delays to planned program changes, plunged the day after Trump's executive order. Argus assessed CCAs for December delivery that day at $26.74/t — at the time their lowest price since November 2022. The lack of certainty around federal legal developments continues to whittle away at bullish signals, leaving market participants to wait for a clear outcome. Adding another layer of uncertainty is the fact that disputes may spill outside of the court system. Following the same logic as of Trump's " national energy emergency ", the US Federal Energy Regulatory Commission (FERC) could hypothetically issue an emergency order to halt carbon and clean energy programs. The recent resignation of a Democratic commissioner, giving Trump the ability to install a Republican majority, could facilitate that pathway. But using FERC to shutter these programs would be on weak legal footing, van Aelstyn said. The Trump administration has no issue using extrajudicial tools to enforce its policies, such as its January pause on federal funding that left states like California — which receives more than $100bn in backing and grants from the US government each fiscal year — grappling with potential budget holes. Two federal courts have said the administration must dole out the funds, but agencies have been slow to comply. "If they can withhold congressionally appropriated research funds for universities because they don't like their policies with regard to free speech on their campuses, what else might they do?" van Aelstyn said. "Withhold Medicaid funding to states where they don't like their renewable energy standards?"

Brazil to hold auction to recover degraded land

Sao Paulo, 28 April (Argus) — Brazil's finance, environment and agriculture ministries will host a second auction to recover 1mn hectares (ha) of degraded lands in all Brazilian biomes except the Amazon, the national treasury said on Monday. The auction will be a part of Eco Invest, a currency-hedging program targeting renewable and low-carbon projects to draw foreign investment, announced in February 2024. The finance ministry and central bank developed the program with the World Bank and the Inter-American Development Bank. The auction is part of New Brazil, a wider energy transition project within the finance ministry. The project aims to finance conversions of degraded lands in different biomes to sustainable and productive ecosystems through private investments. The Amazon biome, the most hit by deforestation, will receive a "customized and exclusive auction" that will be announced later, the environment ministry said. Participants must submit project proposals to the national treasury by 13 June. The government expects to raise up to R10bn ($1.76bn) in the auction. Land-use change and deforestation Emissions from land-use change and deforestation in Brazil reached 1.06bn metric tonnes of CO2 equivalent (tCO2e) in 2023, down by 24pc from a year earlier, according to greenhouse gas tracking platform SEEG. These activities have been leading Brazil's total emissions since 1990 — when historic tracking began — followed by agriculture and cattle raising and the energy sectors. There are currently 280mn ha of farmlands, of which around 29pc are degraded. The government aims to recover up to 40mn ha of grasslands in the next 10 years, the environment and climate change ministry said. The Eco Invest auction will finance the first round of the initiative, dubbed the Green Way program, according to the agriculture ministry. Brazil aims to reduce its total greenhouse gas emissions by 67pc by 2035 from its 2005 levels and sees reducing deforestation as one of its main ways to achieve that goal. The country will host the upcoming UN Cop 30 climate summit in Belem city, in the Amazon biome, as the administration looks to lead the global energy transition .

Power outage hits Spanish refineries: Update 2

Adds details on flight cancellations London, 28 April (Argus) — A massive power cut across the Iberian peninsula has disrupted operations at several refineries, chemical plants and airports in Spain and Portugal today. All five of Repsol's Spanish refineries have been forced to shut, a union representative for the company's workers said. This includes the 220,000 b/d Bilbao refinery, which is operated by Repsol's Petronor subsidiary. Crews are in place, securing units at the refineries. "There is sufficient autonomy in all of them to guarantee the safety of the facilities," the union representative said. Repsol has yet to respond to a request for comment. Fellow Spanish refiner Moeve said it also has halted activity at its refining and chemical plants in the country and is using back-up power generators "to guarantee the safety and control of the system". Moeve operates the 244,000 b/d Algeciras and 220,000 b/d Huelva refineries. Its 250,000 t/yr San Roque base oils plant is also shutting down. Chemicals firm Dow said all plants at its Tarragona industrial complex in Spain have been closed. The longer the power outage lasts, the longer it will take to restart integrated sites. Refineries affected by power outages normally require a 2- to 3-day restart period. It is unclear yet whether any plants have sustained damage. Airports in both countries have also been affected, with 29pc of flights cancelled at Lisbon, according to data from analytics firm Cirium. A total of 96 flights from Portuguese airports have been cancelled today, according to Cirium, while 45 have been cancelled in Spain. Spanish transmission system operator Red Electrica and relevant government bodies are investigating the cause of the blackout. Red Electrica said power has been restored "at substations in several areas in the north, south and west of the peninsula, and consumers in these areas are beginning to be supplied".

Power outage hits Spanish refineries

London, 28 April (Argus) — A massive power cut across the Iberian peninsula has disrupted operations at several refineries in Spain today, sources told Argus. Spanish firm Repsol's Petronor subsidiary halted all units at its 220,000 Bilbao refinery earlier because of the power cut, with black smoke released as part of the security stoppage, market participants said. Shutdowns are also under way at Moeve's 250,000 t/yr San Roque base oils plant and at Repsol's 135,000 b/d La Coruna refinery, sources said. Flaring has been seen at Repsol's 180,000 b/d Tarragona refinery as a result of a response system being activated at the site, according to petrochemical sources. Moeve and Repsol have yet to respond to a request for comment. "The refineries need to be brought to a safe state," a trade union representative for Repsol workers said. "The crews are in place, securing the units. There is sufficient autonomy in all of them to guarantee the safety of the facilities." Chemical sites will also be affected by the power outage. The longer the power outage lasts, the longer it will take to restart integrated sites. Refineries affected by power outages normally require a 2-3 day restart period.
