Digital public goods (DPG) that caught my eye:
Dagens forskning kräver ofta tekniskt avancerade metoder och verktyg. Det ställer höga krav på medarbetarnas kompetens. Trots behovet har det saknats karriärvägar i Sverige för individer som är intresserade av den teknik- och metodutveckling som krävs för att driva och utveckla framtidens forskningsinfrastrukturer. Men med start den 1 april 2023 finns en sådan karriärväg på KI – potentiellt den första i landet.
Därför har KI nu etablerat en ny karriärväg för medarbetare som är intresserade av tekniska och metodologiska aspekter av forskning. Två befattningar skapas: forskningsinfrastrukturspecialist och senior forskningsinfrastrukturspecialist. Anställningarna kan bli aktuella både inom centrala forskningsinfrastrukturer och i enskilda forskargrupper.
I would like to have a PDF viewer that lets me click a button (or press a key) to move backwards in the PDF file's git history. In effect, git checkout <commit> file.pdf but automatically moving back in the commit history on each keypress.
Combined with something like the overview mode of pdfpc, that could make for a very efficient way to glance through the history of a PDF file, such as a thesis or a beamer presentation.
So far I have not found any PDF viewer software with something akin to that.
Maybe I should just open the PDF in VSCodium and use the built-in git support? Would that provide something similar?
Lemmy
- https://browse.feddit.de (search communities across all instances, seems to work better than the search built-in to Lemmy instances)
- https://join-lemmy.org/instances
- https://lemmyverse.net
Lemmy communities (think subreddits) are given in this format: !communityName@instanceName.
Since Lemmy is on the Fediverse, you can follow Lemmy communities (think subreddits) from Mastodon, just replace the ! by @, and you should find the account name.
Lemmy Android apps:
- https://join-lemmy.org/apps
- Jerboa, Android app made by Lemmy's developers [I could not figure out how to switch to another instance without logging in first]
- lemmur is listed on F-Droid, but on its Github page the app clearly states that it's no longer maintained.
Will add more as I learn about them. I only care about FOSS projects.
LXD
See my Ansible role that installs and configures LXD and provisions LXC containers.
Docker
I have some experience with Docker containers. Prefer LXC if I have the choice.
I have written an Ansible playbook to setup containers with docker-compose as part of a as-yet not-public project for InvenioRDM.
Podman
No hands-on experience yet.
Singularity
Hm, interesting. Could it be better than Docker for sharing something like a thesis with "all batteries included", I wonder?
Singularity can convert Docker containers to Singularity, or can run containers directly from Docker Hub

Solar Protocol is a web platform hosted across a network of solar-powered servers set up in different locations around the world. A solar-powered server is a computer that is powered by a solar panel and a small battery. Each server can only offer intermittent connectivity that is dependent on available sunshine, the length of day and local weather conditions. When connected as a network, the servers coordinate to serve a website from whichever of them is enjoying the most sunshine at the time.

Solarpunks were prescient when they asked (in 2012):
What would computing look like if it had to get its power from purely local and renewable sources? What is the potential of low-and-no-power computing and sensor networks?
Sverige
- 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).
- Uppsala Vatten och Vattenfall ska bygga en station för vätgas-tankning av tunga fordon, stöds med 48 MSEK från Energimyndigheten.
- Uppsala Vatten får 2 miljoner SEK i EU-stöd för att planera vätgasproduktion. (Energinyheter.se)
Misr
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.
Asia
- 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.
