Petrobras banking on renewable fuels, niche refining
Brazil's state-controlled Petrobras is developing green diesel and other niche refining businesses as part of its effort to reduce emissions.
Earlier this year, the company concluded refinery tests on its patented hydrotreated vegetable oil (HVO) production technology. The co-processed renewable fuel uses up to 10pc vegetable oils to produce a drop-in fuel that is chemically identical to petroleum diesel.
Petrobras' HVO diesel, also known as green diesel, reduces emissions by 70pc compared to conventional diesel and by 15pc compared to biodiesel, downstream director Anelise Lara said in a call with analysts this week.
Production of renewable diesel is technically possible at the company's existing refineries and has already been tested at the 208,000 b/d Presidente Getulio Vargas refinery (Repar) in Parana state, Lara said. Repar is among the refineries that Petrobras plans to divest.
While Petrobras is in the process of exiting conventional biofuels production, the company is evaluating investments in greenfield biokerosene projects, as well as the construction of dedicated co-processed green diesel refineries.
"We are waiting for approval from the CNPE (national energy policy council) and the ANP (hydrocarbons regulator) to begin selling our renewable diesel in Brazil," she said. "Recognition that our renewable diesel meets the requirements of the Renovabio (biofuels law) is an important step to making these projects economically viable."
The ANP conducted a public hearing process between July and September regarding the classification of HVO and renewable diesel. The agency received nearly 40 contributions from market participants and is expected to release its recommendations to the CNPE later this year or in early 2021.
In a preliminary designation, the ANP stopped short of classifying HVO as biodiesel as Petrobras had hoped. Instead, it sided with Brazil's biodiesel and agricultural industry associations, which asserted that only 5pc of Petrobras' green diesel comes from renewable sources while 95pc of its feedstock remains fossil fuel.
Lara highlighted that the company's renewable diesel reduces the "collateral impact" of biodiesel use on engines, which "suffer" from conventional biodiesel blends.
Brazil's biodiesel producers' association Ubrabio rejects claims that biodiesel causes engine damage.
The expansion of second-generation biofuels production is part of Petrobras' new niche refining strategy, which will focus on environmentally friendly products with a renewable content, Lara said. The company is also planning to concentrate its refining assets in populous southeastern Brazil, while it divests half of 2.2mn b/d of refining capacity in other parts of the country.

Etanol hidratado impulsiona início da safra 2024-25
Sao Paulo, 26 April (Argus) — A produção de etanol no Centro-Sul aumentou 7,2pc na primeira quinzena de abril em relação ao ano passado, com produtores ainda favorecendo o hidratado em meio à demanda crescente. As usinas da região entregaram 841.000m³ ao mercado na primeira quinzena da safra de 2024-25, em comparação com 784.000m³ no mesmo período do ano anterior, segundo os dados mais recentes da União da Indústria de Cana-de-Açúcar e Bioenergia (Unica). A produção de etanol hidratado subiu 39pc e impulsionou a alta anual, totalizando 693.000m³. Já o processamento de anidro, utilizado como mistura na gasolina, caiu 48pc, para 174.000m³. As usinas permanecem destinando mais matéria-prima para o E100, em um cenário de paridade favorável para o biocombustível frente à gasolina na bomba. O hidratado está mais vantajoso para os motoristas em 80pc do mercado de combustíveis leves, disse a Unica. As plantas do Centro-Sul venderam 1,3 milhão de m³ de etanol para o mercado doméstico em abril, salto de 41pc na variação anual. As vendas de hidratado representaram 902.355m³ deste total, alta de 61pc, enquanto as de anidro subiram 14pc, para 448.431m³. Já as exportações totalizaram 52.104m³, queda de 6,2pc. O mix de produção na quinzena foi de 56,4pc para o etanol e 43,6pc para o açúcar, em comparação com 62pc para o biocombustível no mesmo intervalo em 2023. No período, a moagem de cana-de-açúcar avançou 14pc, para 15,8 milhões de t, à medida que a temporada inicia suas operações. Até 16 de abril, 171 usinas estavam operando no ciclo de 2024-25, número maior do que as 166 no mesmo intervalo do ano anterior. A Unica espera que mais 54 unidades recomecem as atividades durante a segunda metade do mês. O etanol à base de milho representou 32pc do volume total produzido na primeira parte de abril, somando 270.500m³, crescimento de 12pc na comparação anual.

Lyondell Houston refinery to run at 95pc in 2Q
Lyondell Houston refinery to run at 95pc in 2Q
Houston, 26 April (Argus) — LyondellBasell plans to run its 264,000 b/d Houston, Texas, refinery at average utilization rates of 95pc in the second quarter and may convert its hydrotreaters to petrochemical production when the plant shuts down in early 2025. The company's sole crude refinery ran at an average 79pc utilization rate in the first quarter due to planned maintenance on a coking unit , the company said in earnings released today . "We are evaluating options for the potential reuse of the hydrotreaters at our Houston refinery to purify recycled and renewable cracker feedstocks," chief executive Peter Vanacker said on a conference call today discussing earnings. Lyondell said last year a conversion would feed the company's two 930,000 metric tonnes (t)/yr steam crackers at its Channelview petrochemicals complex. The company today said it plans to make a final investment decision on the conversion in 2025. Hydrotreater conversions — such as one Chevron completed last year at its 269,000 b/d El Segundo, California, refinery — allow the unit to produce renewable diesel, which creates renewable naphtha as a byproduct. Renewable naphtha can be used as a gasoline blending component, steam cracker feed or feed for hydrogen producing units, according to engineering firm Topsoe. Lyondell last year said the Houston refinery will continue to run until early 2025, delaying a previously announced plan to stop crude processing by the end of 2023.

Germany urges closer NDC-climate finance link
Germany urges closer NDC-climate finance link
Berlin, 26 April (Argus) — German federal chancellor Olaf Scholz today stressed the need for nationally determined contributions (NDC) to the Paris climate deal to provide a framework and incentive for climate finance. NDCs — emissions cut targets which countries must draw up and regularly update under the Paris agreement — should provide "clear roadmaps for decarbonisation" to incentivise and reassure private investors, Scholz said at the 15th Petersberg climate dialogue in Berlin, a forum which paves the way for the UN Cop climate conference negotiations later this year. Drawing up an NDC is also about creating good framework conditions for investments in the individual countries themselves, Scholz said. In updating their NDCs, countries have an opportunity to secure investments in green technologies, he said. "Private investors are concerned about a reliable regulatory framework and good governance." Scholz echoed German foreign minister Annalena Baerbock's remarks made at the opening yesterday, when she proposed an "interlocking" of countries' NDCs with investment plans. Baerbock stressed the idea goes beyond getting the countries together to improve their NDCs. It would, for instance, ensure that fossil fuel producers announcing plans to reduce their production do not get penalised by a cut to their credit rating on the financial markets, she said. And it would be about facilitating matchmaking between the private sector in developed countries, and bringing together the ambitions enshrined in the NDCs with instruments ensuring they can be financed, Baerbock said. She gave the example of Barbados, which she said is using its NDC "not just as a national climate action plan but also as a national investment plan", by creating a bank that brings together various factors "linking climate-policy planning, project implementation, and public and private financing". Both Scholz and Baerbock reiterated calls for larger developing countries that have "significantly" contributed to emissions in the past 30 years, and which have the financial means to contribute, to do so. Cop 29 will be held in Baku, Azerbaijan, in November. Finance will be a key topic as countries must decide on a new global goal, the so-called New Collective Quantified Goal (NCQG) on Climate Finance, to replace the pledge missed by developed countries to give $100 bn/yr to developing countries by 2020. Baerbock called for a new annual climate finance budget for developing countries of $1 trillion. Germany plans to modernise its bilateral debt conversion programme, Scholz said. "This is not a panacea, but vulnerable middle-income countries that are willing to reform could also be eligible for climate debt conversion in the future," he said.

EU adopts Net-Zero Industry Act
EU adopts Net-Zero Industry Act
London, 26 April (Argus) — Members of the European Parliament (MEPs) have adopted Net-Zero Industry Act, which plans to allocate funds towards the production of net-zero technologies. The act provides a pathway to scale up development and production of technologies that are critical towards meeting the EU's recommendation of net-zero greenhouse gas (GHG) emissions by 2050. This would include solar panels, electrolysers and fuel cells, batteries, heat pumps, onshore and offshore wind turbines, grid technologies, sustainable biomethane, as well as carbon capture and storage (CCS). The act is designed to help simplify the regulatory framework for the manufacture of these technologies in order to incentivise European production and supply. It also sets a target of 40pc production within the EU for its annual "deployment needs" of these technologies by 2030. Time limits will be instated on permit grants for manufacturing projects, at 12 months if the manufacturing capacity is under 1 GW/yr and 18 months for those above that. It will introduce time limits of nine months for "net-zero strategic projects" of less than 1 GW/yr and 12 months for those above. This is further complemented by the introduction of net-zero strategic projects for CO2 storage, to help support the development of CCS technology. The act was met with positive reactions from the European Community Shipowners' Association (ECSA), which said the bill will set the benchmark for member states to match 40pc of the deployment needs for clean fuels for shipping with production capacity. ECSA said the Net-Zero Industry Act will be instrumental in supporting the shipping industry to meet targets set under FuelEU Maritime regulations , which are set to come into effect next year.
