So it seems that around 2020 there was a flurry of posts about this project, describing it as "alpha". So the fact that the project is still alpha five years later is perhaps not very encouraging. But it is still actively developed, which is more than you can say about most other projects in this field. The Google stranglehold on casting continues to be heavily felt, unfortunately.

Sverige

• In Skåramåla (Småland) eight wind turbines combined with 65k PV panels make up the largest "hybrid" renewable power plant in Sweden. In operation since 2024. Expected annual production from wind is 125 GWh, and from solar PV 2 GWh. 1, 2, 3
• In Tomteboda, Stockholm's largest PV roof-mounted plant, produces 400 MWh per year (1465 PV panels covering an area of 4000 m²). Co-owned by Areim and Blackstone and operated by Obligo Real Estate. (2021)
• The largest solar power plant in Sweden is built by a home-owner's co-op (HSB Södermanland) in cooperation with the energy company Energiengagemang. 41600 PV panels with a total power of 14 MW.
• In Morgongåva (40 km west of Uppsala) the logistics center of online pharmacy Apotea features Sweden's largest roof-mounted PV array with a capacity of 2.3 MW, enough to supply the building's entire annual electricity demand. Built by Solkompaniet. SVT.
• The ports of Stockholm and the port of Södertälje together have almost 4 GW of solar PV panels, and have plans for more.

Misr

• Benban solar park in southern Egypt is one of the world's largest PV plants, covers an area of 37 km² and has a power generation capacity of 1.65 GW (given the site's insolation expected to yield 3.8 TWh per year).

• Belgium's first floating PV plant. On a man-made lake on a site owned by Sibelco, a raw material producer.
• Spanish energy company Iberdrola commissioned a 500 MW solar PV park at Núñez de Balboa in the western Spanish region of Extremadura. At the time Europe's largest PV plant, as seen by NASA's Earth Observatory. The project cost €300 million and is made of 1.43 million PV panels. Via @S_Johan_Lindahl.

Asia

• I cannot find any updates on the status of the 1.1 GW Al-Henakiyah PV power plant that is supposed to go online in 2025 (or 2026 according to Masdar, which has a nice PDF summary of the project). NS Energy, Masdar
• Announcement of a large planned solar PV plant in Garadagh, Azerbaijan expected to produce 500 GWh annually. To be built by Masdar and it is co-funded by Abu Dhabi Fund for Development, the Asian Development Bank, the European Bank for Reconstruction and Development (EBRD), and Japan International Cooperation Agency. NS Energy
• Oman seems to be on a roll. Their governmental energy company Hydrom (recently created to spearhead their green energy transition) is planning a massive green hydrogen project with a capacity to produce 750 kiloton/year (if I understand correctly). 1, 2.
• In Qinghai province, China, a 2.2 GW solar PV plant was connected to the grid in 2020 (at the time the world's largest solar plant).

Africa

• A large hybrid PV and battery plant has commenced operation in South Africa. The billion-dollar facility is owned by Norwegian Scatec ASA and South African investment company H1 Holdings (51% and 49%, respectively). The plant will supply the state-owned utility Eskom 150 MW of dispatchable power for 16.5 hours per day year-round. The facility comprises 540 MW PV and 1140 MWh battery storage. PV Magazine

Americas

• In the five first months of 2023 the United States power sector saw more electricity generation from wind and solar (combined) than from coal for the first time ever. Many other countries have already passed this particular milestone (or phased out coal entirely), so welcome to the club, yankees, and keep it up.

Oceania

• In southern Australia, a 4 MW concentrating PV plant combined with 50 MWh thermal storage for almost round-the-clock power generation is now in operation. The Carwarp power plant is run by RayGen. The site uses triple-junction GaAs solar modules with almost 38% efficiency paired with water-based thermal energy storage. Each tower (there is four of them) has just over 4 m² of photoactive area producing 1 MW of electricity and 2 MW of heat (ΔT=90℃).
• 10 GW of solar power in Australia for Singapore.
• The largest PV plant in New Zealand sits atop a wastewater pond.
• The Nauru Solar Power Development Project - Battery Energy Storage System is a 6 MW solar plant and a 2.5 MWh battery storage system that will increase the share of renewable electricity in Nauru from 3% to 47% (like many other Pacific islands, Nauru relies almost entirely on diesel generators for power), which is expected to fully cover the island nation's current daytime electricity needs.

• Shell got a lot of good PR a few years ago on the back of news that they would install hydrogen filling stations across California in cooperation with Toyota. Now they have announced their complete withdrawal from light-duty (read: private cars) hydrogen filling stations in the state.

Road vehicles

• The Hague is the first Dutch city with a taxi fleet running on H₂ (Toyota Mirai, specifically) (2020-04).
• As part of the European Commission's JIVE project, a dozen H₂ buses for Bolzano, Italy. The buses are manufactured by Solaris and have a range of 350 km on a single tank of LH2 (2019-07).
• FlixMobility (parent company of Flixbus) plans to operate fuel cell coaches on long-distance routes (2019-11). This as part of the research project HyFleet together with its partners Freudenberg Fuel Cell e-Power Systems and ZF Friedrichshafen AG, overseen by the German Federal Ministry of Transport and Digital Infrastructure, with start of commercial operation slated for 2024. More sources: 1.
• The first H₂-powered double decker buses have started operation in Aberdeen, UK (2021-02). The project was funded by the city, the EU, and the Scottish government, for 15 buses costing about 0.5 million GBP apiece.
• Gross-Gerau district in Germany plans for 80 H₂-powered buses in its fleet by 2028. I wonder how many buses the city operates in total.
• Hyundai plans to sell 1600 heavy trucks in Europe, and cooperates with Hydrospider for the H₂ supply.

Trains

• San Bernardino county in California awarded a contract for a H₂-powered train in 2019 to Stadler to run by 2024. I thought southern California was densely populated - why not electrify the tracks? Fuel cells are better than dirty and loud diesel locomotives, I suppose. This is the first H₂ fuel cell train in the US, and many other places in the US are quite sparsely populated, so let's hope it is followed by more.

Ships

• The Norwegian Public Roads Administration is to operate the world's first H₂-powered ferry connecting its fjords. The ship is built by Norled and has a carrying capacity 299 passengers and 80 cars. Details on its power train have not been forthcoming.
• A river vessel on the Rhone river with a powertrain built by ABB, supported by the European Commission's Fuel Cells and Hydrogen Joint Undertaking (FCH JU) and in cooperation with other parties.
• The first H₂-powered ferry in the US has started serving San Franscisco Bay. It takes 75 passengers, has three fuel cell stacks, and a top speed of 20 knots. The project was awarded a $3 million grant by the California Air Resources Board. For reference, there are about 1000 passenger ferrys operating in the United States.
• The world's first LH2 carrier has been put into service ferrying grey H₂ (meaning H₂ produced from fossil sources) from Australia to markets in Japan. The vessel was built by Kawasaki Heavy Industries and comes equipped with a tank able to hold 1250 m³ of liquified H₂ at a temperature of -253℃ (20 K).

• Map (maintained by the association of the Swedish Energy companies, aka "Energiföretagen") of Swedish green hydrogen projects as of 2024.
• In Älghult, Kronoberg county, Metacon and Uppvidinge Vätgas have launched a H₂ filling station connected to its own electrolyser powered by a dedicated wind turbine, making the station self-sufficient. No word on the technical details yet. (2023-09-01)
• 20 MW electrolyser in operation at Hofors mill, operated by Ovako and delivered by Hitachi Energy (formerly ABB, if I'm not mistaken). It seems to be getting its power from the grid, not any dedicated PV or wind plant. The produced hydrogen gas (3500 m³/h) is used to heat steel before rolling and also to fill fuel cell trucks. The project is the result of a collaboration between Ovako, Hitachi Energy, Volvo, H2 Green Steel, Nel Hydrogen and supported by the Swedish Energy Agency (2023-09-05).
• The world's first off-grid and public hydrogen refill station was installed in 2019 in Mariestad, Sweden. Electricity from a 250 kW PV array is used to run an electrolyser with the ability to produce 46 ton H₂ per year. The station has two storage tanks with a total capacity of 345 kg H₂ at 200 bar. Anyone can fill up their tank with H₂ at 700 bar at a cost of 90 SEK/kg, and the station itself required an investment of 30 million SEK, most of which was financed via grants (mostly from the EU). This refill station should soon be joined by others in Sweden under the "Nordic Hydrogen Corridor" banner. Technical know-how behind this project was provided by Nilsson Energi as well as researchers from Stockholm university, KTH, and Uppsala university. This project has been mentioned in other sources: 1, 2, 3, 4.
• Mariestad municipality (again), I suppose riding high after their success with the off-grid H₂ refill station with storage and PV, has set out to build a preschool that would be completely energy independent by having its own PV panels on the roof and a battery storage bank large enough to cover two days consumption, along with an electrolyser and H₂ storage tanks. The battery bank will even out daily energy peaks, and the stored H₂ is meant to cover electricity and heating during the less-than-sunny Nordic winter (by means of a fuel cell). More sources: 1, 2, 3, 4. The project ran into regulatory issues, but they were resolved, and the preschool including its off-grid-capable energy system was inaugurated in January 2022.
• A small-scale electrolyser in Umeå, Sweden (running off-grid, it seems) operated by Svevia (a government-owned corporation) and meant to supply two of their own fuel cell vehicles. The electrolyser was supplied by Oazer. At present, this is only the fourth such electrolyser in operation in Sweden.
• Spanish fertiliser company Grupo Fertiberia intends to build a 600 MW water electrolyser in the Luleå-Boden area by 2026 at the earliest, fed with renewable electricity from nearby hydropower and windpower. The produced H₂ will be used to synthesise NH₃ (1500 ton/day), which would in turn feed a new fertiliser plant (to the tune of half a million ton per year, would be Sweden's first and only; Sweden imports around 600 000 tonnes per year). Via InvestInNorrbotten (in Swedish), Grupo Fertiberia (PDF), and Cornucopia (in Swedish).

The political and legal conditions for hydrogen projects in Egypt is improving.

• The Norwegian firm Scatec will build and operate a 100 MW PEM plant near Ain Sokhna producing green H₂ plant intended as feedstock for nearby green ammonia production in cooperation with Fertiglobe PLC. The electrolysis cells will be supplied by Plug Power, and local works by Orascom. (2021-10) This project may also involve MEP and Petrofac (it's unclear to me at the moment if this refers to the same ammonia plant, likely the case).
• Positively massive project, if implemented: 7000 km² of PV and/or wind turbines planned to feed 90 GW of electricity to generate H₂ from water. For comparison, that's an area equivalent to more than 175 Benban's and a nominal power capacity 45x the same. Via FuelCellsWorks and ArabNews. I'm not sure this is feasible, to be honest. I will wait for confirmation.

Europe

• The HOPE consortium plans to build the world's first offshore green hydrogen facility by 2026. The consortium consists of several European companies and is backed by the European Commission. The plan consists of wind power supplying a 10 MW electrolyser fed with treated ocean water and a H₂ pipeline back to shore.
• Uniper and other German companies area currently constructing a 30 MW electrolyser which will be the centre-piece of the Bad Lauchstädt Energy Park, an investment of over 200 million EUR. The hydrogen will supply the TotalEnergies Refinery Central Germany some distance away (the project includes building a pipeline). (2023-06)
• Danish power supplier Ørsted received DKK 35 million from the Danish Energy Agency to build a 2 MW electrolysis plant with attached H₂ storage in partnership with Everfuel Europe A/S, NEL Hydrogen A/S, GreenHydrogen A/S, DSV Panalpina A/S, Hydrogen Denmark and Energinet Elsystemansvar A/S. 600 kg H₂/day, or enough to power around 20 buses.
• Hydrospider operates the largest hydrogen electrolyser in Switzerland at Gösgen with a capacity of 2 MW powered by hydro, able to produce up to 300 ton of H₂ per year (enough for around 50 heavy trucks).
• Shell opens a 10 MW PEM electrolyser at its Rheinland oil refinery in Germany. The plant is slated to start operation in 2024 and produce up to 1300 ton of green H₂ per year. The plant, currently Europe's largest PEM green H₂ electrolyser, was funded by Shell in joint cooperation with the European Commission's Fuel Cells and Hydrogen Joint Undertaking (FCH JU) (2021-07).
• Nel Hydrogen Electrolyser, a division of the Norwegian company Nel ASA, is supplying Iberdrola 20 MW of PEM electrolysers for a green fertiliser project. Press release, SR Vetenskapsradion.
• Icelandic company Carbon Recycling International (CRI) produces methanol (CH₄) from CO₂ collected from a nearby geothermal power plant and from H₂ electrolysed from water using renewable generated electricity in a plant with a capacity of 5 million litres of CH₄/year situated on the outskirts of Reykjavik. Chinese carmaking company Geely (also owners of Volvo Cars) invested in CRI in 2015, and partnered to build what would be the world's largest CO₂-to-fuel factory somewhere in China, planned to recycle 160 000 tons of CO₂ emissions from steel plants every year.
• As part of the H2FUTURE project (a cooperation between Siemens, the Austrian power grid, and others and backed by the European Commission's FCH JU project) 6 MW of PEM electrolysers from Siemens will produce H₂ for steel production at the Voestalpine steel mill in Austria.

Japan

• Fukushima prefecture, Japan, aims to cover 100% of its energy demand with renewable sources by 2040, and towards that aim has built a 10 MW electrolyser that runs off a 20 MW photovoltaic park in cooperation with the National Institute of Advanced Industrial Science and Technology. The electrolyser has a rated capacity of 1200 m³/h H₂(g) (approximately 841 ton/year if my math is correct, assuming NTP). Via @S_Johan_Lindahl.

• A massive (planned) expansion of the Mohammed bin Rashid (MBR) solar park in the UAE brings it total capacity to over 4.5 GW, well on the way to the project's target of 5 GW by 2030. This latest addition cost (LCOE) 1.62 cents/kWh (USD). (2023-09-07)
  The solar park is apparently meant to include electrolysers too.

On a related note, it's too bad Shaarli does not allow others to edit or at least comment on posts (but see this post regarding developments).
But if you really want, I guess you could open the post on its own page (see permalink below) and annotate that page using Hypothes.is.

Inte en rekommendation av någon butik - gör din egen bedömning innan du handlar!

It's time to give up Github. This is my attempt to decrease my use of their "starred repo" functionality, which only helps Microsoft build a more valuable social graph.

I usually use the "star" function in one of two ways: either as a reminder to myself to check back on the project later, or as a way to promote the project (assuming Github will somehow increase the visibility of starred projects).

I reckon both of these abilities can be reproduced by hosting the list myself. Granted, the promotional value for the project is much smaller this way, but in any case the method used by Github to promote starred repos is based on some opaque and unknowable algorithm, and in all likelihood my "stars" were not making much of a difference apart from boosting the egos of some small-project owners (I'm one of them, so I know the feeling). But that's just another way that Github tries to trap us, by gamifying parts of the experience.
In any case, better federation across Gitea instances might help to establish a better way to "star" projects.

I intend to organise this list in the future, but for now, in no particular order:
