California advisory speakers push to delay LCFS vote
California regulators should delay long-awaited changes to the state's Low Carbon Fuel Standard (LCFS) until at least July, members of an advisory committee said yesterday.
Staff-proposed revisions the California Air Resources Board (CARB) could consider at a March meeting would allow too much biofuel and biogas to remain in the state's transportation supply for too long, members of the board's Environmental Justice Advisory Committee (EJAC) and public commenters said during a meeting to discuss the plan.
Speakers on Thursday specifically warned against incentives for renewable diesel production and dairy methane capture, and worried the program as proposed would heap costs on residents who could not afford zero-emissions vehicles. Opposition could further extend dramatic surplus conditions that last month helped drop LCFS spot prices to their lowest level in nearly nine years.
The comments did not constitute a formal recommendation by the full committee. The advisory panel has no voting power on CARB decisions, instead offering the board perspective on rulemakings and policies from historically disadvantaged and under-represented communities.
The committee's reaction and hours of public comment show that LCFS program revisions proposed in December have not satisfied critics who are adamant that the state more quickly transition away from combustion fuels and agricultural feedstocks.
"We hope the board listens to the community and tothe EJAC and postpones this decision because we need to be serious here about the kind of transformation that we need so that our communities do not continue to be the sacrifice zones," co-chairwoman Martha Dina Arguello said.
LCFS requires yearly reductions to transportation fuel carbon intensity. Higher-carbon fuels that exceed the annual limit incur deficits that suppliers must offset with credits generated from the distribution in California of approved, lower-carbon alternatives.
The combination of LCFS, other state carbon incentives and federal tax and renewable fuel mandate programs have made California a leading destination for growing production of renewable diesel and biogas. Renewable diesel last year began to fill more than half of the state's liquid diesel pool and generated roughly 40pc of all new LCFS credits. Biogas, much of it credited through book-and-claim from out-of-state dairies and attributed to compressed natural gas vehicles, generated another 17pc of all new credits in the third quarter of 2023.
Supporters point to these fuels as valuable alternatives that cut the carbon intensity of current vehicles while zero-emissions technologies, especially for medium- and heavy-duty vehicles, catch up. Environmental justice speakers have repeatedly warned that these fuels extend polluted conditions for communities along the fence lines of dairies and converted renewable diesel plants.
The committee in September urged CARB to limit credits for crop-based biofuels and for captured dairy methane. CARB's proposed rulemaking requires new certification for forestry- and crop-based feedstocks by 2028, and limits the credits generated by biogas projects — if they break ground after 2029.
CARB's proposals have failed to address the committee's concerns, and the speed of the rulemaking seemed to allow little time for change, speakers said. Public comment began 5 January and will continue to 20 February. CARB has scheduled a hearing on the rulemaking for its 21 March meeting, which would be the first opportunity for the board to consider voting on the proposal.
"This is a really important rule program, and unfortunately, I think, on both process and substance we have progressed from bad to worse," EJAC co-chair Catherine Garoupa White said.
A delay could also push back the higher-profile elements of the proposed changes, including tougher targets and automatic mechanisms to respond to rising credit supplies. Ten consecutive quarters of new credits exceeding new deficits has amassed more than 20mn t of unexpiring credits available for future compliance. Available credits are likely to continue to grow as long as the status quo remains.

Japan’s FEPC calls for clearer nuclear policy stance
Japan’s FEPC calls for clearer nuclear policy stance
Osaka, 20 May (Argus) — Japan's Federation of Electric Power Companies (FEPC) has called for a clarification of the country's nuclear power policy, to ensure stable electricity supply and alignment with its net zero emissions goal. The call comes as the government reviews its basic energy policy , which was formulated in 2021 and calls for the reduction of dependence on nuclear reactors as much as possible. But Japan's guidelines for green transformation, which was agreed in February 2023, states that Japan should make the most of existing nuclear reactors. Tokyo should clearly state in its new energy policy that it is necessary to not only restart existing nuclear reactors, but also build new reactors, said FEPC chairman Kingo Hayashi on 17 May. Hayashi is also the president of utility Chubu Electric Power. Hayashi emphasised that to utilise reactors, it would be necessary to have discussions regarding financial support, policy measures that would help ensure cost recovery, address back-end issues in the nuclear fuel cycle and conduct a review of nuclear damage compensation law. Japan's current basic energy policy is targeted for the April 2030-March 2031 fiscal year, when the country's greenhouse gas (GHG) emissions is forecast to fall by 46pc from 2013-14 levels. To achieve this, the power mix in the policy set the nuclear ratio at 20-22pc, as well as 36-38pc from renewables, 41pc from thermal fuels and 1pc from hydrogen and ammonia. Japan typically reviews the country's basic energy policy every three years. Nuclear, as well as renewables, would be necessary to reduce Japan's GHG emissions, although thermal power units would still play a key role in addressing power shortages. But Japan has faced challenges in restarting the country's reactors following safety concerns after the 2011 Fukushima nuclear disaster, with only 12 reactors currently operational. Japan's nuclear generation in 2023 totalled 77TWh, which accounted for just 9pc of total power output. Tokyo has made efforts to promote the use of reactors, after the current basic energy policy was introduced in 2021. The trade and industry ministry (Meti) has updated its nuclear policy, by allowing nuclear power operators to continue using reactors beyond their maximum lifespan of 60 years by excluding a safety scrutiny period in the wake of the 2011 Fukushima nuclear disaster. This could advance the discussion on Japan's nuclear stance, especially if the new basic energy policy includes more supportive regulations. The trade and industry ministry started discussions to review the energy policy on 15 May, aiming to revise it by the end of this fiscal year. It is still unclear what year it is targeting and what ratio will be set for each power source in the new policy. But the deliberation would form a key part of efforts to update the GHG emissions reduction goal, ahead of the submission of the country's new nationally determined contribution in 2025, with a timeframe for implementation until 2035.

Houston refiners weather hurricane-force winds: Update
Houston refiners weather hurricane-force winds: Update
Adds Calcasieu comment, update on flaring reporting Houston, 17 May (Argus) — Over 2mn b/d of US refining capacity faced destructive winds Thursday evening as a major storm blew through Houston, Texas, but the damage reported so far has been minimal. Wind speeds of up to 78 mph were recorded in northeast Houston and the Houston Ship Channel — home to five refineries with a combined 1.5mn b/d of capacity — faced winds up to 74 mph, according to the National Weather Service . Further South in Galveston Bay, where Valero and Marathon Petroleum refineries total 818,000 b/d of capacity, max wind speeds of 51 mph were recorded. Chevron's 112,000 b/d Pasadena refinery on the Ship Channel just east of downtown Houston sustained minor damage during the storm and continues to supply customers, the company said. ExxonMobil's 564,000 b/d Baytown refinery on the Ship Channel and 369,000 b/d Beaumont, Texas, refinery further east faced no significant impact from the storm and the company continues to supply customers, a spokesperson told Argus . Neither Phillips 66's 265,000 b/d Sweeny refinery southwest of Houston nor its 264,000 b/d Lake Charles refinery 140 miles east in Louisiana were affected by the storm, a spokesperson said. There was no damage at Motiva's 626,000 b/d Port Arthur, Texas, refinery according to the company. Calcasieu's 136,000 b/d refinery in Lake Charles, Louisiana, was unaffected by the storm and operations are normal, the refiner said. Marathon Petroleum declined to comment on operations at its 593,000 b/d Galveston Bay refinery. Valero, LyondellBasell, Pemex, Total and Citgo did not immediately respond to requests for comment on operations at their refineries in the Houston area, Port Arthur and Lake Charles. A roughly eight-mile portion of the Houston Ship Channel from the Sidney Sherman Bridge to Greens Bayou closed from 9pm ET 16 May to 1am ET today when two ships brokeaway from their moorings, and officials looked in a potential fuel oil spill, according to the US Coast Guard. The portion that closed provides access to Valero's 215,000 b/d Houston refinery, LyondellBasell's 264,000 b/d Houston refinery and Chevron's Pasadena refinery. Emissions filings with the Texas Commission on Environmental Quality (TCEQ) are yet to indicate the extent of any flaring and disruption to operations in the Houston area Thursday evening, but will likely be reported later Friday and over the weekend. Gulf coast refiners ran their plants at average utilization rates of 93pc in the week ended 10 May, according to the Energy Information Administration (EIA), up by two percentage points from the prior week as the industry heads into the late-May Memorial Day weekend and beginning of peak summer driving season. The next EIA data release on 22 May will likely reveal any dip in Gulf coast refinery throughputs resulting from the storm.

Rio Grande do Sul remaneja fornecimento de gás
Rio Grande do Sul remaneja fornecimento de gás
Sao Paulo, 17 May (Argus) — O fornecimento de gás natural no Rio Grande do Sul teve que ser redistribuído em razão das enchentes históricas no estado, com o diesel potencialmente voltando como combustível a usinas de energia para deixar mais gás disponível para a produção de GLP (gás de cozinha). O gasoduto Gasbol, que abastece o Sul do Brasil, não tem capacidade para atender à demanda da refinaria Alberto Pasqualini (Refap), da usina termelétrica de Canoas — controlada pela Petrobras — e das distribuidoras de gás natural da região, disse Jean Paul Prates, o então presidente-executivo da Petrobras, no início desta semana. A distribuidora de gás de Santa Catarina ajustou sua própria rede local para atender aos picos de demanda no Rio Grande do Sul por meio da malha de transporte de gás. A usina térmica de Canoas está operando com geração mínima de 150 GW, sendo 61pc provenientes de sua turbina a gás. A usina foi colocada em operação para restabelecer o fornecimento adequado de energia depois que as linhas de transmissão no Sul foram afetadas pelas enchentes. A Petrobras planeja usar um motor a diesel para aumentar a geração de energia. O atual custo variável unitário (CVU) para o diesel na usina de Canoas é de R1.115,29/MWh. A companhia petrolífera também está operando a Refap a 59pc de sua capacidade instalada máxima. Fortes chuvas no Rio Grande do Sul desde 29 de abril trouxeram inundações sem precedentes ao estado, causando uma crise humanitária e danos à infraestrutura. O clima extremo deixou 154 mortos, 98 desaparecidos e mais de 540 mil deslocados, segundo a defesa civil do estado.

Brazil's Rio Grande do Sul reallocates gas supply
Brazil's Rio Grande do Sul reallocates gas supply
Sao Paulo, 17 May (Argus) — Natural gas supply in Brazil's Rio Grande do Sul had to be redistributed because of the historic floods in the state, with diesel potentially making its way back as an power plant fuel to leave more gas available for LPG production. Gasbol, the natural gas transportation pipeline that supplies Brazil's south, does not have capacity to meet demand from the 201,000 b/d Alberto Pasqualini refinery (Refap), state-controlled Petrobras' Canoas thermal power plant and natural gas distributors in the region, according to Petrobras' then-chief executive Jean Paul Prates said earlier this week. The Santa Catarina state gas distributor has adjusted its own local network to meet peak demand in neighboring Rio Grande do Sul via the pipeline transportation network. The Canoas thermal plant is running at its minimum generation at 150GW, with 61pc coming from its gas turbine. The plant was brought on line to reinstate proper power supply after transmission lines in the south were affected by the floods. Petrobras plans to use a diesel engine to increase power generation. The current approved fuel cost (CVU) for diesel in the Canoas plant is of R1,115.29/MWh. Petrobras is also operating Refap at 59pc of its maximum installed capacity, at 119,506 b/d. Heavy showers in Rio Grande do Sul since 29 April brought unprecedented flooding to the state, causing a humanitarian crisis and infrastructure damage. The extreme weather has left 154 people dead, 98 missing and over 540,000 people displaced, according to the state's civil defense.
