Energy and climate highlights compiled for October 4, 2026, with summaries, links, and brief commentary.
I. Oil Supply and Gulf Shipping
1. Two tankers struck over the weekend as Iran restates seven conditions for Hormuz (Shipping)
Summary:
CNBC reported on October 4 that the United Kingdom Maritime Trade Operations centre said a crude tanker was hit by an unknown projectile about four nautical miles east of Oman on Saturday, and that another tanker was struck on Sunday in the Strait of Hormuz, with damage to its engine room. Iranian Parliament Speaker Mohammad Bagher Ghalibaf said Sunday, in comments carried by Nour News, that the strait will not reopen until seven conditions based on the Islamabad Memorandum are met, including a halt to U.S. "acts of aggression," an end to the naval blockade of Iranian ports and to economic warfare, and the release of Iranian assets. Yemen's Houthis said they targeted an Aramco facility in Riyadh on Saturday with ballistic missiles and drones in retaliation for Saudi attacks on Sanaa and other provinces. A witness described smoke and fire. Saudi authorities have not commented, and Aramco did not immediately respond. Before the war that began on February 28, about a fifth of the world's oil moved through the strait. CNBC also noted that after the G7 announced a release of diesel and crude stocks on Friday, Brent settled down 6 cents at $102.25 a barrel and West Texas Intermediate settled down $1.76 at $91.11.

Commentary:
The stock release held Friday's oil price to a few cents, while Sunday's strikes and the unconfirmed Riyadh attack show the route itself is still not open.
2. The U.S. energy secretary says diesel should fall below $6 a gallon before long (Policy)
Summary:
CBS News published the October 4 transcript of Energy Secretary Chris Wright on Face the Nation. He repeated that gasoline and diesel prices should keep falling by around Election Day, citing rising supplies through the Strait of Hormuz in recent weeks, record U.S. gasoline production, and gasoline demand easing after the summer driving season. Host Margaret Brennan said diesel is about $6 a gallon. Wright said the price is already down a little over 20 cents and should fall below $6 before long, though he would not name the day. He called the G7 plan to release 100 million barrels over four months through the IEA, with a large diesel release front-loaded within 20 days, "a big deal," and said Russian diesel exports have stopped and China is no longer exporting diesel or gasoline. Asked whether an export ban is fully ruled out, he did not answer yes or no, saying the president discusses price levers every day. He confirmed that, under the relevant Lindsey Graham legislation, the president must decide by October 18 whether to put tariffs on the largest buyers of Russian fuel, China and India, and he declined to predict the decision.

Commentary:
The secretary treated a move below $6 as the direction of travel, while an export ban and the October 18 tariffs on China and India remain open switches on the price.
II. Grids, Storage, and Carbon Capture
3. India approves Green Energy Corridor Phase III with 50 GWh of storage (Grid)
Summary:
ETEnergyworld reported on October 4 that India's Cabinet approved the third phase of the Green Energy Corridor on Wednesday, aimed at congestion and renewable curtailment as solar and wind grow. The outlay is 1,86,405 crore rupees, about 1.86 trillion rupees. Energy-Storage.News, in an October 2 report, converted that total to about $19.3 billion. Of the outlay, 1,36,378 crore rupees go to intra-state transmission and 50,000 crore rupees to battery storage over seven years, with 54,082 crore rupees in central support to offset intra-state transmission charges. The scheme will add 51,126 circuit kilometres of lines and nearly 229 GVA of transformation capacity to evacuate up to 135 GW of renewable energy, plus 50 GWh of batteries to store surplus green power and supply it outside solar hours. More than 8,000 GWh of renewable electricity was curtailed in the first quarter of fiscal 2026-27. Santosh Kumar Sarangi, secretary of the Ministry of New and Renewable Energy, said about 70 percent will be greenfield projects awarded through tariff-based competitive bidding, to be built, owned, operated, and maintained by transmission service providers. The other 30 percent will be brownfield upgrades recovered on a cost-plus basis. Battery deployment will be tied to domestic-content rules, with guidelines to follow technical consultations. The last Phase I project is expected by the end of the current fiscal year, and Phase II projects by March 2028.

Commentary:
Putting 50 GWh of storage inside the corridor means India is buying the lines and the ability to keep curtailed power at the same time.
4. The Dongfang 1-1 carbon-injection platform is built, designed to store more than 1 million tonnes of CO2 a year (Carbon capture)
Summary:
China News Service reported on October 4 that Offshore Oil Engineering, based in Tianjin, said the topsides of the new central platform at the Dongfang 1-1 gas field, China's first offshore demonstration of carbon dioxide injection to boost gas recovery, are complete and have entered commissioning. Once in operation, the project is designed to store more than 1 million tonnes of carbon dioxide a year in subsea formations. Dongfang 1-1, China's first self-operated offshore gas field and a carbon-rich field, has produced more than 50 billion cubic metres of gas since it started up in 2003. The platform weighs nearly 17,000 tonnes, stands taller than a 28-storey building, and has more than 10,000 square metres of deck. It will capture and purify carbon dioxide produced with the gas and inject it back underground under pressure. Yu Fasong, the project lead at CNOOC Hainan, said the scheme closes the loop from capture and purification to storage and enhanced recovery, uses a combined cryogenic distillation and membrane process to remove carbon dioxide from natural gas, localizes key equipment, cuts energy use by 20 percent versus conventional decarbonization, and raises the gas recovery rate by more than 12 percent. The topsides will be commissioned in Qingdao and then shipped to the South China Sea. The jacket is already installed in the Yinggehai basin. In service, the platform will be tied to 12 other platforms, including Dongfang 13-2 and Dongfang 29-1. Beijing News reported the same day that production is planned for 2027. The jacket has eight legs and 12 skirt piles, is 77.2 metres tall, weighs nearly 8,000 tonnes as installed, and was launched 113 kilometres from Dongfang city in Hainan. Installation of the topsides at sea is set for next month.

Commentary:
The platform is still being commissioned in Qingdao, and storage above 1 million tonnes a year is the design figure for a 2027 startup.
5. After support for Canada's Pacific pipeline, Pathways carbon capture still has no binding commitment (Carbon capture)
Summary:
The Toronto Star reported on October 4 that, after the Liberal government backed a fast-tracked pipeline, the remaining box in the bargain with Alberta is the Pathways carbon-capture project, which is still not agreed and would not cancel the extra emissions from the new oil. Prime Minister Mark Carney said Thursday in Fort McMurray that Pathways would help cut 16 million tonnes a year, equivalent to taking 90 percent of Alberta's cars off the road, and would create an additional 40,000 jobs and more than $16 billion in GDP. The project, sponsored by the five largest oilsands companies, would move greenhouse gases by pipeline for underground storage. Alberta's own description of the pipeline estimated that the new production needed to fill Pacific Link could raise greenhouse-gas emissions by 15.5 million to 18.7 million tonnes before any Pathways reductions. Janetta McKenzie, director of the oil and gas program at the Pembina Institute, said there is no binding commitment and no real penalty for not building it. The agreement Alberta and the federal government signed with oilsands companies in July requires Pathways to be operating by 2035, two to three years after the pipeline is expected to enter service. When first pitched in 2021, Pathways was designed to sequester 22 million tonnes by 2030. The newer memorandum between Carney and Premier Danielle Smith requires only 6 million tonnes by 2035, plus another 10 million tonnes of reductions by 2045. The Oil Sands Alliance, Ottawa, and the province must produce a detailed construction plan by November 15. Natural Resources Minister Tim Hodgson told the Star that producers are unlikely to sign up for Pathways if they do not expect incremental production.

Commentary:
Carney's figure is 16 million tonnes a year, Alberta's own estimate of extra emissions is 15.5 million to 18.7 million, and the two are not yet the same contract.
III. Climate Policy and Extreme Weather
6. Newsom signs a coal-terminal review law as Oakland wins a $1 billion lawsuit (Coal)
Summary:
KQED reported on October 4 that a proposed coal export terminal in West Oakland took two hits this week. On Wednesday, a federal court in Kentucky threw out a $1 billion lawsuit against Oakland by Insight Terminal Solutions, one of the developers. U.S. District Judge Benjamin Beaton abstained because the case likely belonged in a California court, and he vacated a 2025 bankruptcy ruling that had found Oakland could owe the company $230 million to $654 million. The same day, Governor Gavin Newsom signed Assembly Bill 40, which requires an environmental impact report before a large-volume bulk coal facility is built. The law applies to any such new facility in the state. Its author, Oakland Assemblymember Mia Bonta, wrote it for the West Gateway terminal. An investor report said that, if approved, the facility would ship more than 13 million tons of coal a year overseas and store it in the open. The site is part of the former Oakland Army Base. The Trump administration announced a $75 million investment in June. Oakland Bulk and Oversized Terminal is still moving ahead after winning appeals last year. The investor report's "open-air bunkers" contradict earlier developer assurances of covered silos.

Commentary:
The billion-dollar damages risk is off the table for now, and the review law puts an export plan of more than 13 million tons of coal a year back into environmental scrutiny.
7. Courts find the EPA's grant termination unlawful, and Arizona and the Hopi may recover $181 million for solar (Solar)
Summary:
The Arizona Daily Star reported on October 4, citing Cronkite News, that Arizona and the Hopi Tribe could regain about $181 million for solar in low-income communities after two federal judges ruled that the Trump administration unlawfully ended the Solar for All program. The EPA awarded nearly $7 billion in April 2024 under the Inflation Reduction Act. The Trump EPA terminated the program in August 2025, when an audit found only about $71 million had been disbursed. Federal records show Arizona received $42,000 of its $156.1 million grant, and the Hopi Tribe received $421,000 of $25.1 million. On September 18, U.S. District Judge Mary McElroy in Rhode Island ruled that money already promised was obligated and was not covered by the July 2025 law's repeal of unobligated funds. On September 22, U.S. District Judge Tanya Chutkan in Washington, D.C., upheld a challenge by Harris County, Texas, which stood to lose $54 million. Neither ruling directly ordered the grants restored. The EPA said it is reviewing whether to appeal. A May court declaration from the Governor's Office of Resiliency said the state expected the program to help 11,232 moderate- and low-income households save $165 million on electricity and cut 96,000 tons of carbon dioxide a year. The Hopi Utilities Corporation's grant was meant to bring electricity to about 600 homes on the reservation. A 2023 Department of Energy report said 35 percent of homes there lack electricity. Energy manager Fletcher Wilkinson said planning was finished and the tribe was ready to build when the funding stopped.

Commentary:
The courts said the money was already obligated, but they did not order it paid out, and Arizona has actually received $42,000.
8. Heavy rain in Catalonia kills two people, with one still missing (Extreme weather)
Summary:
Deutsche Welle reported on October 4 that flooding from torrential rain in Catalonia, in northeastern Spain, had killed two people by Sunday, with at least one person missing. Catalan firefighters said one person died when a wall collapsed at a campsite in Tordera, north of Barcelona, and another drowned in a flooded garage in Montornes del Valles. Rescuers were also searching in Pineda de Mar, about 52 kilometres north of Barcelona. Spain's AEMET weather agency said more than 100 millimetres of rain fell overnight in numerous locations. Civil protection warned people near the Besos River that it could overflow and told them to move to upper floors if water entered. Homes flooded and vehicles were submerged in towns near Barcelona, local rail service was disrupted, flights at Barcelona airport were canceled or delayed, and shops closed early. Regional leader Salvador Illa urged the greatest caution. The storm is linked to the pattern Spain calls a DANA, or cold drop. In October 2024, a related pattern killed 238 people in eastern Spain, mostly in Valencia. A study published in 2026 found that human-caused climate change intensified that rainfall. Deutsche Welle noted that the finding does not automatically apply to this Catalonia flood.

Commentary:
The deaths were at a campsite wall and in a flooded garage, and the weather agency recorded more than 100 millimetres overnight around Barcelona and Girona.
9. Thailand's disaster agency says floods have hit 3.26 million people, with 329,000 households and 4 deaths in Bangkok (Extreme weather)
Summary:
The Nation reported on October 4 that Nirat Pongsitthithaworn, director-general of the Department of Disaster Prevention and Mitigation, said the command centre's 6 a.m. assessment found flooding across 27 provinces and Bangkok affecting 1,171,165 households and 3,262,676 people, in 154 districts, 1,209 subdistricts, and 8,790 villages. Bangkok had 329,000 affected households and four deaths. Water in the capital was starting to fall, while authorities watched the Chao Phraya River and downstream dam releases. Levels were falling in the northern and northeastern areas listed, and still rising in parts of the centre and east: 4,785 households in Uthai Thani with water rising, and 58,960 households in Chachoengsao with water rising. Prachin Buri reported 46,160 households and seven deaths, Sa Kaeo six deaths, Kanchanaburi two, Chanthaburi two, and Saraburi one. The department attributed the flooding to prolonged heavy rain and water arriving from the north into the central region. The Meteorological Department forecast thunderstorms, gusty winds, and isolated heavy to very heavy rain over upper Thailand from October 4 to 7, with rainfall increasing in the centre, east, and south from October 8 to 13.

Commentary:
The national count is still 3.26 million people in floodwater, Bangkok has only begun to recede, and Chachoengsao and Uthai Thani are still rising.
10. Crete starts counting the damage as floodwater recedes, with eight people still trapped in the Samaria Gorge (Extreme weather)
Summary:
Kathimerini reported on October 4 that, as floodwater began to recede, the damage from severe weather that has hit southern Greece and especially Crete since Wednesday was becoming clearer, with infrastructure, crops, and livestock affected and inspections under way across the island. Around Profitis Ilias in the Heraklion region, officials reported damage to livestock, rural roads, and vineyards, and the wine sector has started an initial assessment. Rainfall was especially heavy in Lasithi in the east, damaging roads and flooding farmland, including on the Lasithi Plateau. New road collapses and landslides were reported around Ierapetra on Sunday. The fire service said it had carried out 79 rescues since Saturday. On Sunday morning, 47 people were evacuated from hotels and short-term rentals in Ferma and Koutsounari in Lasithi. Officials said they were not in immediate danger. Eight people remained trapped in the Samaria Gorge in the southwest, where continued rain and high water blocked a safe rescue. The report said the group includes a doctor and has medicine and enough supplies to last until Wednesday. Rain in some areas was comparable to about a year's precipitation. The distribution operator HEDNO was repairing damaged power poles. Large parts of Crete remain under emergency status at least through Sunday. The weather has killed two people: an elderly livestock farmer in Rethymno on Thursday, and a 58-year-old woman on holiday who was struck by lightning on Rhodes on Friday.

Commentary:
The rescue count is in, the eight people in the gorge have a window only until Wednesday, and the losses to vines and roads are still being tallied.
Today's Summary
- Two tankers were struck around Hormuz over the weekend, and Iran restated that the strait stays closed until seven conditions are met. The Houthis said they hit an Aramco facility in Riyadh; Saudi authorities and the company have not confirmed it. Brent still settled Friday at $102.25 a barrel.
- The U.S. energy secretary said diesel is already down a little over 20 cents and should fall below $6 a gallon before long. He did not rule out an export ban, and he did not predict whether tariffs will be placed by October 18 on China and India for buying Russian fuel.
- India's Green Energy Corridor Phase III is about 1.86 trillion rupees, with 50 GWh of storage and evacuation for up to 135 GW of renewables. The Dongfang 1-1 offshore carbon-injection platform is built, designed to store more than 1 million tonnes of CO2 a year, with production planned for 2027. Canada's Pathways project still has no binding commitment, and Alberta estimates that filling the new pipeline could add 15.5 million to 18.7 million tonnes of greenhouse gases.
- Oakland's coal-terminal lawsuit was thrown out, and California now requires an environmental report first. About $181 million in solar grants for Arizona and the Hopi has not been ordered restored. Floods killed two people in Catalonia, 3.26 million people are affected in Thailand, and parts of Crete saw about a year's rain.
Daily Framing:
Today was a "the sea lane is still shut, reserves are being talked down, and the rain reached several cities at once" day in the energy and climate cycle — tankers were hit again around Hormuz over the weekend, Brent stayed above $102, and the U.S. energy secretary put diesel below $6 before the election; India is buying lines and storage, China's offshore carbon-injection platform has entered commissioning, Canada's capture project is still unsigned, and Catalonia, Thailand, and Crete put extreme rain on the same day.
