Sep 18, 2026 · Energy & Climate Daily Digest
A roundup of energy and climate headlines for Sep 18, 2026, with summaries, links, and brief commentary.
I. Policy and Carbon Markets
1. EU's first full-scale CO2 storage project starts up: Denmark's Greensand at 400,000 tonnes a year (Carbon capture)
Summary:
Reuters and EU Today reported on Sep 18 that King Frederik X opened Greensand at the Port of Esbjerg, putting the EU's first full-scale geological CO2 storage project into commercial operation. INEOS Energy leads the project with Harbour Energy and Denmark's state-owned Nordsøfonden. First-phase capacity is up to 400,000 tonnes a year, with a design path to 4 million to 8 million tonnes annually. CO2 from Danish biomethane plants is liquefied, trucked to Esbjerg, and shipped for injection into the depleted Nini West field about 250 km offshore and 1,800 metres below the seabed. Under the Net-Zero Industry Act the EU wants at least 50 million tonnes of annual injection capacity by 2030; the first phase is still under 1% of that goal.

Commentary:
Europe now has an operating capture-ship-store chain, but 400,000 tonnes against a 50-million-tonne 2030 goal shows the infrastructure gap has only just been named.
2. EU Council backs extra free carbon allowances for energy-intensive industry (Carbon market)
Summary:
ccarbon reported on Sep 18 that member states, at ambassador level, set a Council position on a revised law to increase free allowances from 2026 to 2030 for sectors covered by heat and fuel ETS benchmarks and exposed to carbon leakage. They agreed to use about 88 million allowances available for free allocation, which the Commission estimates would save those sectors about €6 billion in carbon costs, plus about 33 million allowances previously unallocated because installations missed existing conditions. The move is part of the broader reform of the EU Emissions Trading System and is meant to keep energy-intensive industry competitive.

Commentary:
Opening commercial storage and handing out more free permits on the same day shows Brussels is still buying industrial stay-put with extra allowances, offsetting the carbon-price signal.
3. Eurogroup weighs an energy windfall tax in Dublin as Brent stays above $100 (Policy)
Summary:
Euronews reported on Sep 18 that Eurogroup and Ecofin ministers meeting in Dublin on Friday and Saturday are discussing a windfall tax on firms profiting from energy-price swings. With the Middle East war continuing, Brent remains above $100 a barrel, and the EU does not expect inflation back at 2% before the end of 2027. Economy Commissioner Valdis Dombrovskis said the Commission can share national practice; German Finance Minister Lars Klingbeil wants models by the October Ecofin meeting, Spain's Carlos Cuerpo is in favour, and France's Roland Lescure said he cannot back a text he has not seen. On Sep 14, EU diesel pump prices ranged from about €1.20 a litre in Malta to about €2.50 in Finland and Denmark, with tax gaps larger than the crude shock itself.
Links:
Commentary:
The windfall tax is still a discussion of best practice; household bills are still set by national fuel taxes, refining capacity, and import routes, not by a Dublin principle.
4. Washington signs cap-and-invest rules aimed at linking with California-Quebec (Carbon market)
Summary:
ccarbon reported on Sep 18 that Washington Ecology Director Casey Sixkiller signed the CR-103 order of adoption on Sep 17, amending the state's Cap-and-Invest Program and greenhouse-gas reporting rules. The rule is to be filed with the state code reviser on Sep 23 and takes effect on Oct 24. The changes implement Climate Commitment Act amendments and are intended to make Washington's market officially ready to link with the California-Quebec market. They also adjust the timing and consignment of no-cost allowances for electric utilities and clarify baseline adjustments for emissions-intensive, trade-exposed industries.
Links:
Commentary:
While federal policy is tearing up power-plant climate rules, the West Coast is still building a linkable compliance pool—the U.S. climate split is now written into market plumbing.
II. Renewables, Storage and Hydrogen
5. Thailand doubles the People's Solar quota to 10 GW, buying surplus at 2.20 baht for 20 years (Solar)
Summary:
Xinhua, carried by The Peninsula on Sep 18, reported that Thailand's National Energy Policy Council raised the household People's Solar quota from 5 GW to 10 GW, enough for about one million households. Purchases use net billing: households use their own power first and sell surplus at 2.20 baht (about $0.07) per kWh, capped at 5 kW per meter, with contracts extended from 10 to 20 years and the extra intake covering 2026 to 2028. Panels may now go on the ground and on water as well as rooftops. The energy and interior ministries and three state utilities have one month to produce a grid-readiness plan covering forecasting, real-time monitoring, network control, and battery storage; the industry ministry must also draft a recycling plan for panels and batteries.
Links:
- The Peninsula — Thailand plans massive 10 GW expansion in household solar power
- Reuters — Thailand doubles capacity of public solar power scheme to 10 GW, official says
Commentary:
Matching contracts to panel life and allowing ground and floating arrays widens who can join; the one-month grid plan shows officials know 10 GW of household solar fails at the connection, not at the slogan.
6. Malaysia sets a 14 sen/kWh charge for firm green power, with a 2028 commercial-operation deadline (Green power)
Summary:
The Star reported on Sep 18 that the Energy Transition and Water Transformation Ministry launched a CRESS acceleration package: a 14 sen per kWh system access charge for firm green electricity, plus contracts of at least 10 years between renewable developers and green consumers, to improve bankability. Projects using the package must reach commercial operation by Dec 31, 2028, or lose eligibility and fall under whatever charge applies then; extensions will not be considered. Since the scheme launched in 2024, 11 developers and eight green consumers have registered with the Single Buyer, covering 3,148 MW.
Links:
Commentary:
Locking the access charge and a hard in-service date is how corporate green power becomes lendable—the next bottleneck is contract length and fee predictability, not another letter of intent.
7. New South Wales eight-hour grid battery is operating: 50 MW / 400 MWh (Storage)
Summary:
Electrek reported on Sep 18 that RWE's Limondale battery near Balranald in south-west New South Wales, next to an existing solar farm, is registered and operating in the National Electricity Market after AEMO's final operational sign-off earlier this year. The project is 50 MW / 400 MWh, able to discharge for eight hours, and uses 144 Tesla Megapacks. It charges at about 100 MW and discharges at 50 MW, filling in roughly four hours and releasing over eight. It was the only winner of NSW's first long-duration storage tender under the Electricity Infrastructure Roadmap and is backed by a Long-Term Energy Service Agreement; two more eight-hour batteries with the same support are moving through the pipeline.
Links:
Commentary:
Fast charge and slow discharge is storage shaped to the solar duck curve: two-hour batteries steady frequency, eight-hour batteries start to touch the evening-to-night coal shift.
8. SMA opens a German inverter factory with more than 60 GW of annual capacity (Manufacturing)
Summary:
pv magazine Global reported on Sep 18 that German inverter maker SMA inaugurated its Gigawatt Factory in Niestetal, near Kassel, on Sep 17. Annual capacity exceeds 60 GW. The site covers about 46,000 square metres and cost about €80 million. Lines build 2.6 MW to 5 MW central inverters, string inverters up to 180 kW, and the containerised Sunny Central Flex, which combines AC/DC conversion with medium-voltage equipment. The gear is aimed at utility-scale PV, storage, solar-plus-storage, and electrolysis, including grid-forming use. SMA said European peers together add capacity to about 100 GW, and that China-sourced parts are only about 2% to 4% of its utility-scale inverters.
Links:
Commentary:
The capacity figure is not the story; the story is Europe treating medium-voltage integration and grid-forming inverters as energy-security hardware to be built at home.
9. After Masdar's exit, OMV still proceeds with a 140 MW green-hydrogen plant in Austria (Hydrogen)
Summary:
Reuters reported on Sep 18 that Austrian oil and gas group OMV will continue its Austrian hydrogen project after Abu Dhabi's state-owned Masdar unexpectedly withdrew. The partnership, announced last November, had Masdar lined up for an investment of several hundred million euros. The project still costs about €600 million and is largely financed: the European Investment Bank has committed a €450 million loan, and Austria has indicated public funding. The 140 MW electrolyser is planned to start by the end of 2027 and produce up to 23,000 tonnes of green hydrogen a year, which would make it Austria's largest and one of Europe's five biggest. Salzburger Nachrichten reported that OMV attributed the exit to a strategic shift in Abu Dhabi; Masdar was not immediately available for comment. ADNOC still owns 24.9% of OMV.
Links:
Commentary:
A partner walking away did not stop the plant because the loan and public money were already in place—green hydrogen now lives or dies on financial close, not on the launch-day partner list.
10. Hainan's first Hualong One unit enters commercial operation; both units would yield about 18 TWh a year (Nuclear)
Summary:
People's Daily Online reported on Sep 18, citing China Huaneng, that Unit 3 of the Changjiang Phase II plant in Hainan entered commercial operation on Sep 17, the island's first Hualong One reactor. Phase II plans Units 3 and 4 at 1,200 MW each. Once both are complete, annual output can reach about 18 billion kWh, saving more than 6.32 million tonnes of standard coal and cutting about 11.6 million tonnes of CO2 a year. The design combines active and passive safety, implemented 86 design optimisations, reached 98.1% equipment localisation, and switched on a domestic production-management system, HAP, that uses video, 5G, and artificial intelligence.
Links:
Commentary:
For the Hainan free-trade port this is not another demonstration reactor; it writes firm clean power into an island energy ledger, and the next constraint is whether Unit 4 connects on time.
III. Fuel Prices and Extreme Weather
11. Malaysia's economy minister says coal at $148 a tonne will raise power-generation costs (Power prices)
Summary:
Malaysia's The Sun reported on Sep 18, citing Bernama, that Economy Minister Akmal Nasrullah Mohd Nasir said coal at $148 a tonne on Sep 10 will directly raise generation costs. The August average was $130.67 a tonne, up from $129.63 in July. Peak demand on Sep 9 reached 21,949 MW, 4.7% above the August average, but still inside the reserve margin. August Brent averaged $90.88 a barrel, up 8.9% from $83.42, and daily prices surged above $120 this week. LNG averaged $21.87 per MMBtu in August and was approaching $30 by mid-September. The government said it will keep fuel supply secure through December 2026 by diversifying imports, optimising domestic output, and strengthening long-term contracts, and that Malaysia and Thailand signed a production-sharing contract and gas sales agreement for Block A-18-01 in their joint development area.
Links:
Commentary:
The reserve margin can still cover demand, but coal, oil, and gas prices are rising together, so Southeast Asian power risk has shifted from "is there enough power" to "who pays the fuel bill."
12. Northern Vietnam flood toll updated: more than 16,000 homes and 22,000 hectares of crops (Disasters)
Summary:
The Straits Times reported on Sep 18, citing Bloomberg and a government statement, that northern Vietnam has seen downpours since Sep 14, with as much as 653 mm in some areas, triggering floods and landslides that killed three people, inundated more than 16,000 homes, and damaged more than 22,000 hectares of rice and other crops. The Hanoi-Ho Chi Minh City railway was flooded about one metre deep, and some north-south trains were suspended on Sep 17 and Sep 18. Thanh Hoa mobilised more than 29,000 officials and soldiers. A separate government statement said natural disasters have killed or left missing 63 people in Vietnam in 2026, with losses of about 2.2 trillion dong, though financial losses are down 84.9% from the same period in 2025. El Nino is forecast to cut rainfall in central and southern Vietnam by 10% to 50% later in 2026, potentially affecting about 350,000 hectares of rice in the Mekong Delta.
Links:
Commentary:
Official language already pairs this flood with a later drought: the north is still draining water while the Mekong Delta is flagged as the next season's rice-water risk.
13. Global ocean logs 100 straight days of record heat as El Nino adds to the warming (Climate)
Summary:
Mongabay reported on Sep 18 that University of Maine Climate Reanalyzer data show the global ocean outside polar regions set record-high average sea-surface temperatures on every day from Jun 2 to Sep 10, beating the same date in every year since 1982. Copernicus recorded 21.10°C on Aug 22; Climate Reanalyzer put the peak at 21.18°C between Aug 22 and Aug 27. Climate Central's Zachary Labe said more than 90% of excess heat from fossil-fuel emissions goes into the ocean. The El Nino that began in June, which NOAA rates as very strong, is expected to peak toward the end of 2026 and continue into 2027. An analysis in Advances in Atmospheric Sciences found the ocean absorbed 23 zettajoules in 2025, more than 43% above 16 zettajoules in 2024.
Links:
Commentary:
One hundred record days is a raised baseline, not a one-off heatwave; El Nino is the amplifier, and cutting emissions is what turns the heat source down.
14. Tropical Storm Dujuan nears eastern Japan, with up to 250 mm of rain possible in the Ogasawara Islands (Disasters)
Summary:
The Japan Times reported on Sep 18, citing the Japan Meteorological Agency, that Tropical Storm Dujuan was about 170 km south-southeast of Chichijima at 3 p.m. Friday, moving west-northwest at 35 kph, with central pressure of 975 hPa, sustained winds near 108 kph, and gusts up to 162 kph. It is expected to pass near the Ogasawara Islands from Friday into Saturday, approach the Izu Islands on Sunday, and may near the Pacific coast of eastern Japan from Sunday into Monday. The Ogasawara Islands could see as much as 250 mm of rain in the 24 hours through noon Saturday, the Izu Islands up to 200 mm in the next 24 hours, and parts of Kanto up to 150 mm. Waves could reach 7 metres around the Ogasawara and Izu islands. The agency warned of landslides, flooding in low-lying areas, and swollen rivers.

Commentary:
The track may still turn north and leave quickly, but holiday rainfall and wave heights already move the risk from remote islands to low ground along the capital region's coast.
Today's Summary
- On the same day the EU started commercial CO2 storage and agreed more free allowances for energy-intensive industry, carbon management moved into hardware while competitiveness politics diluted the carbon price.
- Dublin discussed an energy windfall tax with Brent still above $100 a barrel, while Malaysian coal and gas prices rose together and turned the fuel bill into a power-price problem.
- Thailand's doubled household-solar quota, Malaysia's locked corporate green-power charge, Australia's eight-hour battery, and Germany's inverter factory show the next contest is grid access, duration, and local manufacturing.
- Northern Vietnam's flood losses were revised upward, the global ocean posted 100 straight days of record heat, and Tropical Storm Dujuan neared eastern Japan.
Daily Framing:
A day when carbon hardware started running while prices and ocean heat pressed at the same time—storage and long-duration batteries came online, but extra free permits and higher fuel costs undercut how tolerable carbon and power prices can be.
