Australia joins global pledge to cut methane emissions
The Australian government has signed the global methane pledge to cut its methane levels by 30pc by 2030 from 2020 levels, which will mean the country's significant agriculture and gas sectors will have to step up efforts to cut the potent greenhouse gas (GHG) emissions gas.
The ruling Labor government indicated in June that the nation would join more than 120 countries on tackling methane. Methane has a greater global warming potential that is 86 times higher than CO2 when averaged over 20 years and 28 times higher when averaged over 100 years.
"By joining the pledge, Australia will join the rest of the world's major agricultural commodity exporters including the US, Brazil, and Indonesia in identifying opportunities to reduce emissions in this hard-to-abate sector," Australian climate change and energy minister Chris Bowen said.
The Australian government will partner with industry to decarbonise the economy and pursue emissions reduction initiatives across energy and waste sectors including capturing waste methane to generate electricity, Bowen said.
Australian government investment in lowering GHG emissions will include up to A$3bn ($1.91bn) from the A$15bn National Reconstruction Fund to support investment in low emissions technologies and component manufacturing and agricultural methane reduction, the minister said.
Canberra will provide a further A$5mn in funding for the second stage of the methane emissions reduction in livestock (Meril) programme to develop technologies to deliver low emission feed supplements to grazing animals and determine their technical viability and commercial potential, Bowen said.
The pledge does not require Australia to focus solely on agriculture, or reduce agricultural production or livestock numbers, the minister said. The former conservative coalition government would not sign the methane pledge when it was in government up until it lost the national election in May.
"As a result of signing the pledge, the Australian government will not legislate or introduce taxes or levies to reduce livestock emissions," Bowen said.
Around 26pc of Australia's greenhouse gas (GHG) emissions in 2021 were from methane emissions, according to the latest GHG inventory data. Agricultural GHG emissions represents about 13pc of Australia's total emissions, while 42pc of the sector's emissions are from methane.
Most of this is the methane produced by cattle and other livestock through the fermentation of plants in their stomachs. Australia's expansion of LNG exports over the past decade to around 80mn t/yr have also seen an increased contribution to GHGs coming from methane emissions in the upstream sector.
The Labor government has already deepened its GHG emissions reduction target to 43pc by 2030 from 2005 levels compared with the 26-28pc cut pledged by the previous administration.
"For agriculture the pledge will reinforce our demonstrated commitment to sustainability and ongoing access key markets as an export orientated sector," National Farmers Federation (NFF) president Fiona Simon said.

FERC OK’s Virginia Transco gasline expansion
FERC OK’s Virginia Transco gasline expansion
New York, 1 May (Argus) — The US Federal Energy Regulatory Commission (FERC) today gave Williams the green light to expand natural gas capacity to Virginia by 101mn cf/d (2.9mn m3/d) on its Transco pipeline. The project, called the Commonwealth Energy Connector, involves the construction of 6.3 miles of new pipeline within Transco's existing right-of-way in southeast Virginia, near the border with North Carolina. The project also includes adding horsepower at compressor station 168, west of the new pipeline segment. Williams plans to begin construction this winter and put the project into service by the end of 2025. Environmental advocacy group Sierra Club opposed the project, arguing FERC failed to assess its potential greenhouse gas emissions, rendering its National Environmental Policy Act analysis moot. FERC disagreed, conceding that although the project's final Environmental Impact Statement demonstrated it would contribute to greenhouse gas emissions, the effects of those emissions on the environment could not be measured because FERC lacks the methodology to do so. The US south-Atlantic gas market has become more volatile in recent years as gas and power demand have soared, outpacing pipeline capacity expansions in the region. The combined gas consumption of Virginia and North and South Carolina in 2022 averaged 4.7 Bcf/d, up by 69pc from a decade earlier, US Energy Information Administration data show. Regional gas and power consumption is widely expected to continue climbing through the end of the decade on a massive build-out of data centers , especially in Virginia.

US gas industry pins hopes on AI power demand
US gas industry pins hopes on AI power demand
New York, 1 May (Argus) — US natural gas producers and pipelines have pivoted almost in unison this year to talking up what they see as one of the strongest bullish cases for gas this decade: surging electricity demand from yet-to-be-built data centers to power artificial intelligence software. EQT, the largest US gas producer by volume, in an investor presentation last week called growing data center demand the "cornerstone" to the "natural gas bull case." Combining its own research with data from the US Energy Information Administration, the gas giant forecast an increase in gas demand of 10 Bcf/d (283mn m3/d) by 2030 to generate electricity, mostly to run data centers. Its more aggressive data center build-out scenario envisions a whopping 18 Bcf/d increase in gas demand through 2030. Total US gas production is currently about 100 Bcf/d. Kinder Morgan, one of the largest US gas pipeline operators, this month forecast 20pc of US power being gobbled up by data centers in 2030, up from a 2.5pc share in 2022. Cobbling together projections from several consultancies and financial advisories, the company said the electricity needed to run artificial intelligence software alone will comprise 15pc of US power demand by 2030. If just 40pc of that demand is met by gas, that would represent an increase in gas demand of 7-10 Bcf/d, it said. This is roughly in line with the high end of US bank Tudor Pickering Holt's forecast for gas demand to power data centers through 2030 (1.3-8.5 Bcf/d) and well above Goldman Sachs' and consultancy Enverus' projections of 3.3 Bcf/d and 2 Bcf/d, respectively. New tech, old problems Separating the wide ranges of these projections is the highly speculative nature of forecasting demand years into the future for competing energy sources to power next-generation technology. But the major upside and downside risks, analysts say, concern the more humdrum challenges of permitting and building out energy infrastructure. Goldman Sachs expects 28GW, or 60pc, of the generation capacity needed to power new data centers through 2030 will come from natural gas — 9GW from combined cycle gas turbines and 19GW from gas peaker plants. But with an average lag of four years from the time a gas transmission project is announced to the time it enters service, to say nothing of the high probability of litigation being brought by environmentalists and landowners, construction and permitting timelines are "the most top of mind constraint for natural gas," the bank said. Indeed, litigation and opposition from state regulators have ultimately led developers to call off several interstate pipeline projects in the eastern US in recent years. The exception to the rule, Equitrans' 2 Bcf/d Mountain Valley Pipeline is moving forward only because congressional action allowed it to bypass federal permitting hurdles. This is a particular problem for the gas industry's hopes of exploiting the data center boom, as a large share of future data centers are slated to be built in the southeast US, far from the major US gas fields. New data centers representing 2 Bcf/d of gas demand in Georgia probably requires a new pipeline into the southeast, FactSet senior energy analyst Connor McLean said. Southeast premium A significant data-center buildout in the southeast without new pipelines could put upward pressure on regional gas prices, McLean said. This could exacerbate the effects of what has become perhaps the most prominent bullish case for US gas: a massive build-out of LNG export terminals along the US Gulf coast. With new export terminals pulling increasing volumes of gas south along the Transcontinental gas pipeline to super-chill and ship overseas in the coming years, the build-out in data centers will likely produce "an even bigger deficit in that southeast (gas) market," EQT chief financial officer Jeremy Knop told investors last week. "We think that market really, in time, becomes the most premium market in the country," he said. By Julian Hast Send comments and request more information at feedback@argusmedia.com Copyright © 2024.

G7 coal exit goal puts focus on Germany, Japan and US
G7 coal exit goal puts focus on Germany, Japan and US
London, 1 May (Argus) — A G7 countries commitment to phase out "unabated coal power generation" by 2035 focuses attention on Germany, Japan and the US for charting a concrete coal-exit path, but provides some flexibility on timelines. The G7 commitment does not mark a departure from the previous course and provides a caveat by stating the unabated coal exit will take place by 2035 or "in a timeline consistent with keeping a limit of 1.5°C temperature rise within reach, in line with countries' net-zero pathways". The G7 countries are Italy — this year's host — Canada, France, Germany, Japan, the UK and the US. The EU is a non-enumerated member. The announcement calls for accelerating "efforts towards the phase-out of unabated coal power generation", but does not suggest policy action. It calls for reducing "as much as possible", providing room for manoeuvre to Germany, Japan and the US. Coal exports are not mentioned in the communique. Canada and the US are net coal exporters. France, which predominantly uses nuclear power in its generation mix is already scheduled to close its two remaining coal plants by the end of this year. The UK will shut its last coal-fired plant Ratcliffe in September . Italy has ended its emergency "coal maximisation plan" and has been less reliant on coal-fired generation, except in Sardinia . The country has 6GW of installed coal-fired power capacity, with state-controlled utility Enel operating 4.7GW of this. The operator said it wanted to shut all its coal-fired plants by 2027. Canada announced a coal exit by 2030 in 2016 and currently has 4.7GW of operational coal-fired capacity. In 2021-23, the country imported an average of 5.7mn t of coal each year, mainly from the US. Germany Germany has a legal obligation to shut down all its coal plants by 2038, but the country's nuclear fleet retirement in 2023, coupled with LNG shortages after Russia's invasion of Ukraine, led to an increase in coal use. Germany pushed for an informal target to phase out coal by 2030, but the grid regulator Bnetza's timeline still anticipates the last units going offline in 2038. The G7 agreement puts into questions how the country will treat its current reliance on coal as a backup fuel. The grid regulator requires "systematically relevant" coal plants to remain available as emergency power sources until the end of March 2031 . Germany generated 9.5TWh of electricity from hard-coal fired generation so far this year, according to European grid operator association Entso-E. Extending the current rate of generation, Germany's theoretical coal burn could reach about 8.8mn t. Japan Japan's operational coal capacity has increased since 2022, with over 3GW of new units connected to the grid, according to the latest analysis by Global Energy Monitor (GEM). Less than 5pc of Japan's operational coal fleet has a planned retirement year, and these comprise the oldest and least efficient plants. Coal capacity built in the last decade, following the Fukushima disaster, is unlikely to receive a retirement date without a country-wide policy that calls for a coal exit. Returning nuclear fleet capacity is curtailing any additional coal-fired generation in Japan , but it will have to build equivalent capacity to replace its 53GW of coal generation. And, according to IEA figures, Japan will only boost renewables up to 24pc until 2030. The US The US operates the third-largest coal-power generation fleet in the world, with 212GW operational capacity. Only 37pc of this capacity has a known retirement date before 2031. After 2031, the US will have to retire coal-fired capacity at a rate of 33GW/yr for four years to be able to meet the 2035 phase-out deadline.

US Treasury updates SAF tax credit guidelines
US Treasury updates SAF tax credit guidelines
Houston, 30 April (Argus) — The US Treasury Department released long-awaited guidance on tax credit eligibility for ethanol-derived sustainable aviation fuel (SAF) Tuesday, incorporating so-called climate-smart agricultural (CSA) practices. As part of the new guidance, the agencies comprising the SAF Interagency Working Group (IWG) are jointly releasing the 40B SAF-GREET 2024 model, which provides another methodology for SAF producers to determine lifecycle greenhouse gas (GHG) emissions rates of their production for the credit. It also incorporates a pilot program to encourage the usage of CSA practices for SAF feedstocks. In collaboration with the US Department of Agriculture (USDA), the major changes include further guidance on farming practices, including no-till farming, planting cover crops and enhanced efficiency fertilizer. The $1.25/USG 40B SAF credit applies to a qualified fuel mixture containing SAF for certain sales or uses after 31 December 2022, and before 1 January 2025. To qualify for the credit, the SAF must have a minimum lifecycle greenhouse gas emissions reduction of 50pc compared with petroleum-based jet fuel. Additionally, there is a supplemental credit of one cent for each percent that the reduction exceeds 50pc, for a maximum credit of $1.75/USG. The modified version of the Greenhouse gases, Regulated Emissions, and Energy use in Technologies (GREET) also incorporates new data, including updated modeling of key feedstocks and processes used in aviation fuel and indirect emissions. The modified GREET model also integrates key GHG emission reduction strategies, such as carbon capture and storage, renewable natural gas, and renewable electricity. The notice provides a safe harbor for use of the USDA Climate Smart Agriculture Pilot Program to further cut the emissions reduction percentage calculated for domestic soybean and domestic corn feedstocks and for certifying the related requirements. For corn ethanol-to-jet, the pilot provides a greenhouse gas reduction credit if a "bundle" of certain CSA practices — no-till farming, cover crop planting, and enhanced efficiency fertilizer — are used. It would also allow a greenhouse gas reduction credit for soybean-to-jet production if the soybean feedstock is produced using similar CSA practices. This is a pilot program specific to the 40B credit under the Inflation Reduction Act (IRA), which is in effect for 2023 and 2024. A new 45Z-GREET will be developed for use with the 45Z tax credit, which starts on 1 Jan 2025. Given the similar language between section 40B and section 45Z of the IRA regarding methods for determining lifecycle greenhouse gas emissions reduction percentages, it is expected that the positions taken by Treasury and the IRS related to the section 40B credit will be similar for the new clean fuel producer credit under section 45Z. Industry reaction mixed Renewable fuels groups welcome the updated pathway for ethanol-to-jet, but the groups expressed concern over the scope of the guidance. "We are encouraged that, for the first time ever, this carbon scoring framework will recognize and credit certain climate-smart agricultural practices," Renewable Fuels Association president and chief executive Geoff Cooper said. "However, RFA believes less prescription on ag practices, more flexibility, and additional low-carbon technologies and practices should be added to the modeling framework to better reflect the innovation occurring throughout the supply chain." Kailee Buller, chief executive of the National Oilseed Processors Association, also said the new guidance has shortcomings. "We are concerned the requirement to implement climate-smart ag practices simultaneously will limit this opportunity, particularly in parts of the country where it may not be possible to plant a cover crop or the cost to implement new practices is too steep," Buller said. Both groups said they would continue to work with the Biden administration to further opportunities for SAF development.
