Sao Paulo state seeks biomethane boost

  • Spanish Market: Natural gas
  • 13/05/24

Brazil's Sao Paulo state is seeking to capitalize on growing demand for renewable energy, announcing a series of measures to increase biogas and biomethane production across various sectors, including sugarcane, waste management firms and waste agriculture.

As Brazil's largest sugar and ethanol producing state, Sao Paulo has substantial potential to leverage existing infrastructure and resources — especially vinasse, a byproduct of ethanol production — to increase biomethane output.

To boost output, the state government will streamline environmental licensing for new projects through new rules that should attract investment, according to the state's environment undersecretary for energy and mining, Marisa Barros.

The focus will initially be on the sugar and ethanol industry, which can produce 30mn m³/d of biogas. Biogas contains 50pc methane, which can be processed into biomethane, a drop-in substitute for natural gas.

The state is also seeking to attract investment in biogas production from animal waste, which can produce up to 5mn m³/d. The government estimates that roughly 190,000 farms in the state can install biodigestors to produce biogas, which would contribute to lower emissions in the state.

The state agriculture secretary also approved the use of the Sao Paulo agribusiness expansion fund (Feap) for investments in biodigestors as well as new solar power installations. And earlier this year state regulatory agency Arsesp stipulated a discount on distribution fees for biomethane sold on the wholesale market.

Brazil's energy research company EPE sees significant potential for the sugarcane industry to expand biomethane production, in part because it has the advantage of having many mills adjacent to existing gas distribution infrastructure.

In addition to selling the renewable gas on the wholesale market, many mills are using biomethane in their own operations and to substitute diesel in their trucks and machinery, contributing to lower fuel costs and emissions.

Brazil real strongest to dollar since August

Sao Paulo, 3 July (Argus) — The Brazilian real closed today at its strongest level since August, prompted by a weakening greenback globally. The real ended the trading session at R5.41 to the dollar at the end of the session, its strongest since 20 August, when it closed at R5.407. The Brazilian currency has strengthened by almost 5pc to the US dollar over the past 12 months, while it has been gaining ground on the greenback since late December of 2024. Brazil's central bank raised its target interest rate to the highest since July of 2006 to fight an "adverse and uncertain" global economic scenario. Back in May of this year, inflation slowed to an annual 5.32pc from 5.53pc in April, according to government statistics agency IBGE. The DXY dollar index, which tracks the greenback against six other major trading currencies, is near a three-year low, mainly on uncertainty over US president Donald Trump's shifting policies on tariffs and federal spending that have rattled financial markets.

IRA rollback to boost US natural gas demand

IRA rollback to boost US natural gas demand

New York, 3 July (Argus) — Cuts to renewable energy tax credits in the budget bill backed by President Donald Trump will likely increase demand for natural gas this decade to generate electricity, as those tax credits would otherwise subsidize the build-out of competing renewable generation infrastructure, according to analysts and industry insiders. Under the landmark bill, which was passed Thursday by the House after clearing the Senate on Tuesday, wind and solar projects only qualify for the clean energy tax credits in former president Joe Biden's Inflation Reduction Act if they begin construction within the next 12 months or are placed into service by the end of 2027. The accelerated timelines for renewable energy infrastructure "will likely slow the growth of renewable capacity," said FactSet senior energy analyst Trevor Fugita. "The legislation is likely to shift the focus from new renewable generation to new natural gas-fired generation, especially as AI data centers drive energy demand higher," he said. Toby Rice, chief executive of EQT, the second-largest US gas producer by volume, in an interview with Argus last week said the bill's effort at "slowing down some renewables could easily add another 1.5-2 Bcf/d" of US gas demand by 2030, especially as coal-fired power plants retire. "If solar and wind investments decrease, that [power] demand is not going away," said Rice, who identified the rollback of clean energy tax credits as key to the investment thesis for his company, alongside surging power demand for data centers and manufacturing and declining associated gas supply amid weak oil prices. EQT expects to produce 6-6.3 Bcf/d of natural gas equivalent this year. Under a previous House-passed version of Trump's One Big Beautiful Bill that required wind and solar projects to enter service by the end of 2027 to be eligible for IRA tax credits, Energy Aspects projected utility-scale solar installations falling from 32.9 GW in 2024 to 27.5 GW in 2027 and 20 GW by 2029. With the Senate's revised bill offering developers a "safer deadline" of alternatively securing the credits by beginning construction within 12 months of the bill's passage, the consultancy now expects a less steep downward trend through 2029, Energy Aspects head of North American power and emissions Michael Lawn told Argus . But utility-scale solar installations would have been on an upward trend through the end of the decade in the absence of the IRA rollback. Jason Grumet, chief executive of the trade group American Clean Power Association, on Tuesday lamented the Senate-passed bill's "very aggressive" 12-month phase out of clean energy tax credits, calling the bill "a step backward for American energy policy."

Gas integration a center of Mercosur meeting

Buenos Aires, 3 July (Argus) — Presidents of Latin America's Southern Cone common market countries focused on integrating their gas markets as part of this week's semi-annual summit in Buenos Aires, Argentina. Integration of power grids is in place, with countries routinely supplying each other with electricity, and leaders pledged to deepen it and add natural gas integration in a joint declaration signed on 3 July. The bloc, known as Mercosur, includes Argentina, Brazil, Paraguay and Uruguay. Bolivia joined in 2024 and has four years to approve all bloc agreements for full membership. A vast pipeline system exists between Argentina, Bolivia and Brazil, and Argentina's government has approved 31 contracts for gas exports to Brazil through Bolivia, the most recent on 26 June between Argentina's Tecpetrol and Brazil's Eneva. Argentinian foreign minister Gerardo Werthein said the countries agreed to promote investment in production and transportation of natural gas. Another step during the Mercosur meeting was an initial agreement signed by Argentina and Paraguay to study the construction of a 1,050km (630-mile) pipeline that would provide it with natural gas and a link to Brazil. Gas would come from Argentina's Vaca Muerta unconventional formation, which holds 308 trillion cf of natural gas reserves. Paraguay president Santiago Pena said his country, Argentina and Brazil have led electricity integration for more than 50 years and "it is now time to think about new sources. The initial agreement for natural gas is an enormous opportunity for real integration." Other top points of discussion included external plans for new trade deals. Argentinian president Javier Milei, in charge of the meeting, called for the bloc to stop using it "as a shield to protect us" and, instead, use it as a lance for greater trade openness with the world. He cited the conclusion of negotiations on 2 July for a trade agreement with the European Free Trade Association (EFTA), which includes Iceland, Lichtenstein, Norway and Switzerland. Milei and Brazilian president Luiz Inacio Lula da Silva — Brazil will take over the rotating Mercosur presidency from Argentina — said Mercosur was confident it would sign a free-trade agreement with the EU by end-2025. Negotiations closed in December 2024. The presidents also cited potential agreements with a growing list of countries, including the UAE. That agreement could be finished in 2025. The bloc wants to work on trade agreements with Canada. Talks began in 2018, but stalled. Da Silva said Brazil's Mercosur presidency would work to restart those talks. Uruguay's president Yamandu Orsi said the bloc should also dust off the idea of a trade agreement with South Korea. Exploratory talks were held in 2017.

Australia backs Inpex’s Bonaparte carbon capture scheme

Sydney, 3 July (Argus) — Australia's federal Labor government has provided major project status to Japanese firm Inpex's planned 10mn t/yr Bonaparte carbon capture and storage (CCS) project offshore Australia's northern coast. The announcement by Australia's industry minister Tim Ayres reflects the importance of CCS to the nation's net zero aims, Inpex managing director and country chair Tetsu Murayama said on 3 July. The status provides a single entry point for Australian government approvals, project support and co-ordination and assistance with state and territory agencies' regulatory processes. Pre-front end engineering started at the site in April, Inpex said, with initial CO2 injection planned for about 2030. The 9.3mn t/yr Ichthys LNG project based in the nearby city of Darwin is expected to be the first customer. Ichthys reported scope 1 emissions of 6.7mn t CO2 equivalent (CO2e) under Australia's safeguard mechanism in the July 2023 to June 2024 financial year, below its 7.46mn t CO2e baseline and earning 768,900 safeguard mechanism credits (SMCs) as a result. Appraisal works last year identified a high-quality saline aquifer with good prospects for permanent sequestration, Murayama said. Detailed data analysis will be done ahead of any application for a greenhouse gas injection licence. The firm was awarded acreage in the Bonaparte basin in 2022 and reached an initial agreement with Japanese utility Chubu Electric Power for potential CO2 imports in October last year. This followed a May agreement with Japanese power firm Jera to explore a CCS supply chain from Japan to Australia. Japan has limited domestic CCS sites. There are two major CCS projects currently operating in Australia, both of which are onshore: Chevron's 4mn t/yr Gorgon project on Western Australia's Barrow Island and Australian independent Santos' 1.7mn t/yr Moomba facility in South Australia. The technology has been criticised as prolonging fossil fuel usage. But Australia, a major exporter of LNG, has said CCS represents a huge opportunity as the world decarbonises. It passed laws to permit CO2 imports in 2023 in 2023. By Tom Major Send comments and request more information at feedback@argusmedia.com Copyright © 2025. Argus Media group . All rights reserved.
