The White House is preparing a 90-day diesel exports ban despite resistance from Republican lawmakers and oil industry representatives, while analysis warns that suspending foreign diesel sales would ultimately harm the U.S. and benefit China. Oil prices eased Thursday as Iran signaled openness to diplomacy to end the U.S.-Iran war, though the two sides remain far apart, with Brent slipping to $102.54 and WTI to $91.85; separately, Asia's crude imports reached 23.96 million barrels per day in September, the highest since the war began, adding further downward pressure on prices.

On the supply side, U.S. gas supply growth could exceed LNG demand through 2027, while Southeast Asia is nonetheless pressing ahead, developing over 100 GW of gas-fired power capacity and 70 million tonnes per annum of LNG import infrastructure despite Middle East supply risks. China raised retail gasoline and diesel prices in response to global crude gains but capped the increase again to limit domestic market impact, even as the country's fuel inventories hit decade lows, raising concerns about a potential return of export restrictions.

In corporate developments, Italy's Ludoil completed the acquisition of a 51% stake in Sicilian refiner ISAB and announced a €1.3 billion five-year investment in the facility. Takeover target Capricorn Energy raised its production outlook above the midpoint of its 18,000–22,000 boepd guidance range, citing stronger Egyptian output amid the ongoing DNO takeover contest. Pioneer Natural Resources founder Scott Sheffield accused ExxonMobil of orchestrating a 'smear campaign' over collusion allegations that blocked his appointment to the Exxon board following the Pioneer acquisition.

Italy's Senate approved a nuclear revival law that clears the legal path for a new generation of reactors to be built in the country, marking a significant policy shift decades after Italy shuttered its previous nuclear plants.

In U.S. project finance, Ares acquired an 80% stake in a California solar-storage portfolio valued at approximately $800 million from EDP Renewables, encompassing 200 MW of solar under a 20-year PPA and 184 MW of battery storage under a 20-year Capacity Tolling Agreement. Meta signed its seventh PPA with Apex Clean Energy for the 144 MW Starling Solar farm in Gonzales County, Texas, bringing the pair's combined portfolio to approximately 1.2 GW across five states, with commercial operations targeted for 2027. Belgian firm CIOC Energy raised €3 million to trade solar and battery assets, while Recurrent Energy, a Canadian Solar subsidiary, achieved ISO 14001 certification for its environmental management system across nearly 15 GW of contracted O&M projects in nine countries.

On the regulatory and legal front, a federal judge ordered restoration of $7 billion in Solar for All grants, ruling the Trump administration's termination of the Inflation Reduction Act program unlawful; the EPA is reviewing the decision and considering an appeal. The U.S. Energy Secretary dismissed reports and criticized solar power in separate remarks. Santa Barbara County supervisors passed a utility-scale solar ordinance establishing a clear permitting path for solar and battery storage in unincorporated areas. San Diego County's Board of Supervisors unanimously approved the Starlight Solar project, a 100 MW solar facility paired with a 217 MW battery storage system on 588 acres in Boulevard, following concurrent Planning Commission approval. In Kentucky, Lexington's mayor vetoed a farmland solar ordinance that the Urban County Council had passed 8-7, citing concerns over agricultural land precedent; a council override would require nine votes and is expected to be revisited at the October 6 meeting. Nearly 100 residents in Michigan gathered to question solar projects in Huron County, raising concerns about zoning rules and land use.

In manufacturing and supply chain, India's Waaree Energies approved a merger of Indosolar into the group to simplify its corporate structure. Premier Energies commissioned a 7 GW TOPCon solar-cell facility in Andhra Pradesh, raising its total solar-cell capacity to 10.6 GW, while simultaneously targeting June 2027 for the first 6 GWh phase of a 12 GWh battery storage manufacturing joint venture with Germany's RCT Solutions in Telangana. Taiwan-based United Renewable Energy is awaiting a U.S. plant decision on its joint-venture solar module facility with Sino-American Silicon Products, with production scheduled to begin in Q3 2027.

Australia's ARENA committed AU$25 million to the Lightspeed trial, a three-year programme with Equans Solar & Storage testing up to 10 construction and operations technologies to reduce the levelised cost of utility-scale solar, including deployment of an autonomous inspection robot at an Australian solar farm. A new study cited by Germany's Solar Association finds that batteries could unlock 150 GW of additional photovoltaic capacity on existing German grids if storage systems are deployed at substations. UK Power Networks extended its Derms access to IDNO customers, enabling Independent Distribution Network Operator-connected projects, including solar farms and EV charging hubs, to connect faster and at lower upfront cost. Texas has surpassed California in solar capacity, a shift placing Vistra, Clearway Energy, and CenterPoint Energy among the listed companies most directly exposed to evolving ERCOT solar economics and storage demand.

EU Eurostat data show renewables fell slightly year-on-year to 54.1% of electricity generation in Q2 2026, down from 54.3%, as solar's share of renewable output rose to 41.6% but could not offset drought-reduced hydropower; gas generation increased 3.9% over the same period. An industry analysis examines the financial logic behind institutional investment in renewable infrastructure and battery storage, noting that revenue stacking, long-term PPAs, and declining LCOE have made utility-scale solar and BESS increasingly viable as core infrastructure assets independent of subsidy support, even as price cannibalization pressures merchant returns in high-penetration markets such as Germany and ERCOT. In the UK commercial market, data from one installer's 2,610-job order book show battery attachment rates drop sharply above £30,000 project value, with only 12.5% of commercial installations including storage compared with 91.3% at the residential scale, a divergence attributed primarily to the 2022 removal of Triad avoidance benefits under Ofgem's Targeted Charging Review.

At the community scale, Pisgah Energy completed 212 kW of rooftop arrays across five systems at Mountain Housing Opportunities' Star Point Apartments and Lakeshore Villas in Asheville, North Carolina, bringing the nonprofit developer's solar-equipped affordable housing communities to six. Nevada-based Comstock Inc. has developed a recycling process for worn panels, recovering aluminum, silver, copper, lead, and glass at a rate of one panel every six and a half seconds, responding to data suggesting three to four million panels are already exiting service annually in the United States as some installations fail after only 15 to 17 years rather than the projected 25 to 30.

Ørsted and Nuveen completed the inauguration of Borkum Riffgrund 3, a 913 MW offshore wind farm in the German North Sea positioned as one of the country's largest, capable of supplying close to one million households annually; German Federal Minister Katherina Reiche noted the project adds nearly a tenth to national offshore capacity, which has already surpassed 10 GW this year. The facility is owned equally by Ørsted and Nuveen Infrastructure and forms part of Ørsted's 8.1 GW global construction portfolio. European Energy and pension partner Sampension separately brought online the 27 MW Tsoukes Sarres wind park in Greece, now feeding electricity into the grid.

In the Americas, New York State's energy authority announced 1.7 GW in new contracts covering eight storage and thirteen renewable energy projects valued at $3.7 billion, with four wind farms among the awarded developments. Pacifico Energy secured a sea survey license for 1.3 GW for its Nam Trung Bo 3 offshore wind project in Lam Dong Province, Vietnam, advancing early-stage development in Southeast Asia. Australia opened its first offshore wind auction, targeting 2 GW of capacity off Victoria state, with the tender running through August 2027 and contracts expected to be awarded in 2028.

On the supply-chain front, R&S Group signed a framework agreement with NeXtWind for the project-based supply of power transformers to support NeXtWind's wind-farm repowering portfolio, with delivery through R&S Group's ZREW brand; the company noted its transformer capacity in Łódź, Poland, is set to double by 2028. Brookfield Renewable, whose 48,700 MW portfolio spans hydro, wind, solar, and storage, saw its stock decline more than 20% year-to-date even as the company reported 2,600 MW of new PPAs in the second quarter and maintained a dividend yield above 5%, with the payout ratio at 63% as of Q2 and a stated annual dividend growth target of 5% to 9%.

On the European policy front, a leaked Commission staff impact assessment has revealed that post-2030 architecture for renewable hydrogen could shift away from binding national consumption quotas toward an indicative EU-level target and a credit-based demand mechanism, with the draft's central scenario modelling 18 million tonnes of electrolytic hydrogen consumption in 2040. In direct response, 170 firms urge binding targets under the Renewable Energy Directive III be preserved, warning that abandonment would forfeit €15 billion already committed and a further €50–60 billion investment opportunity, a position reinforced by an industry-wide open letter addressed directly to Commission President von der Leyen citing 30 million tonnes per year of potential CO₂ savings. A paywalled account similarly frames the industry's stance as opposition to swapping mandates for flexibility.

Infrastructure construction advanced on multiple fronts. German and French officials held a formal groundbreaking for the MosaHYc cross-border pipeline, a 17-kilometre German segment running from Leidingen to Dillingen that, combined with a 25-kilometre French conversion and new-build section, will eventually link to the European hydrogen core network drawing supply from the Iberian Peninsula, northern Germany, Luxembourg, and Belgium, with pipe-laying scheduled across approximately 18 months. In northern Germany, H2 Mobility commenced trial operations at a hydrogen station near Hannover Airport, positioned on the North Sea–Baltic transport corridor with dispensers supporting 350, 500, and 700 bar refuelling for trucks, buses, and passenger vehicles, backed by up to €5.8 million from Germany's Federal Ministry of Transport; logistics firm Schreck + Batz simultaneously began testing a Hyundai XCIENT fuel cell truck on live delivery routes. In Belgium, Power to Hydrogen commenced commercial AEM electrolyser production at the Port of Antwerp-Bruges, deploying a 500 kW system capable of generating up to 70 tonnes of green hydrogen per year for regional mobility and industrial customers, with a projected levelised cost of approximately €3.86/kg and a second 500 kW unit destined for SINTEF in Norway later this year. EWE separately onboarded Bilfinger for an underground hydrogen storage project, according to Hydrogen Europe's concurrent release.

In steelmaking decarbonisation, Jacobs Solutions extended its contract to oversee construction and assembly management at thyssenkrupp Steel's Duisburg direct reduction plant, a hydrogen-capable facility originally contracted in August 2023 that is designed to produce approximately 2.5 million metric tons of direct reduced iron annually by replacing coal-fired blast furnaces with a hydrogen-based reduction process; a separate valuation analysis notes the stock is trading 29.2% above intrinsic value on the GF Value metric.

Electrolyser technology partnerships expanded at scale. Australian start-up Hysata agreed to supply engineering and performance data for its capillary-fed alkaline units to be modelled within Intercontinental Energy's P2H2Node giga-scale platform, where each 1 GW node is designed to host 800 MW of electrolyser capacity; ICE estimates the technology's claimed 95% system efficiency could yield roughly 120,000 additional tonnes of green ammonia per gigawatt of renewables annually, while Hysata separately secured AUD $49 million from ARENA toward a 50 MW per year commercial production line at Port Kembla. A comparative equity analysis contrasts Plug Power's revenue recovery — total net revenues of $178.3 million in Q2 2026, services revenues up 55.9% year-on-year — against a net loss of approximately $190.1 million in the quarter, while noting that the company secured a 50 MW electrolyser order for Orica's Hunter Valley Hydrogen Hub in Australia, that country's largest renewable hydrogen project to reach final investment decision, and shipped a 1 MW GenEco PEM electrolyser to HWR Hydrogen in New Zealand for heavy-duty dual-fuel truck applications. The H2AccelerateTRUCKS initiative launched an End User Group with 70 participants from fleet operators and hydrogen stakeholders across Europe to advance fuel cell electric truck deployment by 2030. Siltrax introduced a 2–6 kW air-cooled platform for UAV and off-grid applications using silicon bipolar plate technology.

On conventional hydrogen production, Arkema inaugurated a new SMR unit in Jarrie as part of a €10 million investment programme running through 2028. Cefmof Hydrogen backed Finnish carbon-to-syngas start-up Reduciner with a €1.5 million seed round. Maruti Suzuki commissioned a 300 kW green hydrogen pilot at its Manesar facility in India, where the government separately announced that the National Green Hydrogen Mission has awarded incentives covering 8.62 lakh tonnes per annum of production capacity and 3,000 MW per annum of domestic electrolyser manufacturing, with the lowest green hydrogen bid at Rs 279/kg and green ammonia at Rs 49.75/kg signalling improving cost competitiveness.

Natural hydrogen exploration attracted activity across three jurisdictions. New Zealand's government announced it will regulate white and orange hydrogen — both derived from rock through chemical reactions with water — under a geothermal-style Crown access framework that grants operators exclusive exploration rights without state ownership of the resource. In Western Australia, researchers at Edith Cowan University demonstrated in laboratory conditions that powdered magnetite from the Pilbara region's iron-ore deposits produces five times more hydrogen than solid slabs when exposed to water at approximately 200°C under pressure, narrowing the search for viable subsurface reserves to porous, water-accessible formations. In Canada, MAX Power Mining Corp. reported its strongest results to date at the Lawson Discovery in Saskatchewan, described as Canada's first verified natural hydrogen system, with a fifth well planned to step out 30 kilometres to test a potentially larger accumulation. The global NPT threaded hydrogen connectors market, a critical enabling component for high-pressure systems, is forecast to grow at an 8–12% compound annual rate through 2035, with premium high-pressure connectors expected to represent 25–35% of market value by that date.

The U.S. Department of Energy announced $99 million across 21 projects to advance domestic geothermal development, with five projects conducting field-scale enhanced geothermal systems tests and sixteen focused on exploration drilling; data from all projects will be deposited in DOE's Geothermal Data Repository. Among the recipients, Fervo Energy and Quaise Energy together secured nearly $45 million of that pool, with Fervo receiving two grants totaling $20 million for EGS projects in Idaho and Nevada, and Quaise receiving up to $25 million for Project Obsidian, its commercial superhot geothermal plant under construction in Central Oregon targeting reservoir temperatures above 300°C and a Phase 1 output exceeding 50 MW by 2030. Two Colorado-based firms also feature in that same federal initiative: DAVINCI EP LLC will drill horizontal confirmation wells in California, while 400C Energy Inc. will deepen an existing well in Utah.

Separately, the Trump administration's broader geothermal push includes a new Geothermal Center of Excellence launched within the national laboratory network, and the redirection of funds from offshore wind lease buyouts toward geothermal investment — a policy that has generated legal disputes with the offshore wind sector. A Sonoma Clean Power-led coalition, meanwhile, secured a $20 million California state commitment for geothermal development following Governor Newsom's signature on the relevant budget agreement.

In the United Kingdom, a geothermal well drilled more than three miles into Cornwall's granite reached the national grid for the first time, delivering approximately 3 MW of baseload electricity from water held at above 190°C at United Downs — the deepest onshore well ever drilled in the UK. The same geothermal fluid, carrying dissolved lithium at concentrations exceeding 340 parts per million, simultaneously feeds a lithium carbonate extraction unit rated at 100 metric tons annually, with the project backed by a 15-year Contracts for Differences award.

In the Philippines, First Gen Corporation's geothermal subsidiary EDC is upgrading Palinpinon-1's capacity from 112.5 MW to 126 MW by replacing three 37.5-MW turbine-generator units with three 42-MW units, adding 13.5 MW to the Visayas grid without additional steam extraction, with phased completion targeted by end-2027. In Kenya, two geothermal plants at the Menengai fields developed by Globeleq and Orpower 22 have begun supplying 70 MW to the national grid after nearly a decade of delays, lifting Kenya's total installed geothermal capacity above 1,000 MW.

On the institutional side, Oberlin College in Ohio reached carbon neutrality after converting its campus to a low-temperature hot water geothermal district energy system financed with $80 million in Climate Bonds Initiative-certified bonds, with the project subsequently grandfathered into Inflation Reduction Act tax credits. In Needham, Massachusetts, a proposed future middle school is being designed around a ground source heat pump system estimated at roughly $7.1 million — approximately 2% of the $325.4 million project — projected to save up to $6 million over 25 years relative to alternative heating and cooling configurations. In Turkey, legal proceedings against IGNIS H2 Energy's planned geothermal project near Varto have advanced, with an expert site inspection scheduled for October 8 to assess the project's potential impacts on agricultural land, groundwater, biodiversity, and protected species. Finally, a DIY experiment demonstrated that a salvaged 14,000-BTU window air conditioner paired with 2,000 feet of buried PEX tubing can function as a rudimentary ground-source heat pump, producing supply air in the 49–54°F range, though the system remains an unfinished experiment pending full seasonal performance data.

Glencore's Cerrejon mine in Colombia suspended railway operations after explosives struck a train near Uribia in La Guajira on the evening of September 22, marking the sixth infrastructure attack recorded at the site this year; no injuries were reported, the National Army deployed troops to secure the area, and mine production continues while a damage assessment awaits safe access. The 150-kilometer railway connects the open-pit mine — which produced 16.8 million tonnes in 2025 — to Port Bolívar for export, and prolonged repairs risk disrupting coal movement and export volumes. The attacks follow more than 80 blockades at the site this year, linked to community protests over lack of basic services rather than disputes with the company.

Germany's cabinet approved a national roadmap on September 23 committing to phasing out fossil fuels by 2045, the first time the government has made this an explicit policy goal rather than merely pledging carbon neutrality. The plan targets renewables rising from 55% to at least 80% of electricity by 2030, and reaffirms the existing coal exit deadline of 2038 while exploring an earlier 2035 coal deadline. The roadmap, presented at the UN General Assembly in New York, also calls for 2.8 billion euros in EV subsidies, heat pumps to become the primary residential heating system, and new state-funded gas plants to be hydrogen-ready by 2045; Germany becomes the third country to adopt such a national phaseout plan after France and the Netherlands. Economy Minister Katherina Reiche has called for greater flexibility on combustion engines and alternative fuels, signaling internal resistance to elements of the strategy.

A U.S. federal appeals court ruled that the Department of Energy overstepped its authority when it ordered the J.H. Campbell coal plant in Michigan to remain open past its planned retirement, rejecting the "energy emergency" justification as falling outside the narrow statutory backstop of the Federal Power Act. The plant, the most polluting of seven fossil fuel facilities kept online under Trump administration orders, has emitted 1,000 tons of nitrogen oxides and 2,000 tons of sulfur dioxide since being forced to stay open, at a cost of $259 million that the utility is seeking to recover from customers. The ruling sets a precedent affecting similar legal challenges against other retained coal plants, though the administration may seek a rehearing or Supreme Court review. Separately, two Indiana coal plants — units at NIPSCO's R.M. Schahfer station and CenterPoint Energy's F.B. Culley station — have been ordered to remain available through December under renewed Trump administration directives, and the Campbell ruling now clouds the legal standing of those fresh must-run orders.

A new Sierra Club Dirty Truth Report awarded We Energies its worst-ever score of 4 out of 100, citing the utility's third delay in retiring the Oak Creek coal plant and plans to add 1.2 GW of new gas capacity by 2035, driven largely by anticipated AI data center load growth; the utility is also seeking a 14% rate increase that drew over 1,800 public comments, 91% in opposition. The same report scored Mississippi Power at 44 out of 100, noting plans to add 548 MW of new gas and retire all existing coal capacity while investing zero megawatts in renewable energy. Across all 76 utilities graded nationally, the aggregate score fell to 7 out of 100, the lowest in the report's history.

Five years after China pledged to halt overseas coal power financing, a report by the Centre for Research on Energy and Clean Air and People of Asia for Climate Solutions found that two-thirds of planned projects were cancelled, cutting 61.5 GW of capacity and avoiding 6.4 billion tonnes of lifetime CO2 emissions; recent cancellations include 3.4 GW in Zimbabwe, 1.7 GW in Bangladesh, and 1.4 GW in Indonesia, though the report notes that private-sector projects continue and that momentum slowed last year.

In Australia, the liquidators of Bowen Coking Coal have disclaimed the mining lease for the Bluff coking coal mine in central Queensland, transferring responsibility for rehabilitation to the state government's Abandoned Mine Lands Program; the site's estimated rehabilitation cost stands at approximately A$12.25 million, a figure observers consider potentially insufficient given the mine closed mid-operation. Newcastle Coal Infrastructure Group, which operates the coal export terminal at the Port of Newcastle in New South Wales, reported that its tender offer for 4.400% notes expired on September 23, with a consideration of US$993.11 per US$1,000 principal amount and settlement expected September 28; pricing terms were anchored to a 3.500% UST reference security due September 30, 2027, with Citigroup and Goldman Sachs acting as dealer managers. COP31 hosts Türkiye and co-president Australia face criticism that Türkiye's Global Electrification Pledge omits explicit clean-technology language, while Australia's recent approval of the Saraji mine extension — supplying 55 million tonnes of coal through 2055 — undermines both nations' climate credibility ahead of the summit.

Illinois Governor JB Pritzker highlighted the state's progress under the Climate and Equitable Jobs Act at the America Is All In conference in New York, noting the state targets ending private coal generation by 2030 and closing natural gas plants by 2045, while a new 2026 law will add 3 GW of battery storage by 2030. California Governor Gavin Newsom, also in New York for the UN General Assembly, accused the Trump administration of reopening coal plants as policy while blocking ready renewable capacity, and signed a clean energy collaboration agreement with Spain. A study near India's Udupi Thermal Power Plant in Karnataka tested whether fly ash blended with vermicompost can immobilize heavy metals and improve crop growth, finding groundwater pH below acceptable drinking-water standards near the 1,200 MW plant. Shanxi Coking Coal Energy reported that its subsidiary Xingxian Xingxin completed business registration and obtained its operating license.
