Met de nadruk op "kunnen".
Metal oxide frameworks zijn een wetenschappelijk indrukwekkende ontwikkeling, maar de weg naar praktische toepassing is nog zeer onduidelijk.
Herinner je nog buckyballs of koolstofbuisjes (2x Nobelprijs), of perovskiet?

Nobelprijs Chemie naar materialen die PFAS uit water en CO2 uit de lucht kunnen halen

Drie onderzoekers – één uit de VS, één uit Australië en één uit Japan – worden bekroond voor hun werk rond een geheel nieuwe klasse van materialen. Hun metaal-organische netwerken kunnen onder meer giftige of schadelijke stoffen ‘vangen’.

Echt eh. Vanaf enkele rechtse trolls ze gevonden heeft wordt het daar zo triestig dat het terug hilarisch wordt. 😆

Because Belgium is so well connected, it also makes us attractive for BESS investments. You can serve BE, NL, DE and FR markets from here.

Our geography doesn't allow for a increase in hydro. But the light gray battery discharge you see there is mostly capacity added in just the last year or so. There is a pipeline of ~9 GW of planned large-scale BESS, but uncertain how much will reach FID (cannibalisation effects).

Technisch kunnen ze idd veel meer, uitdaging is vooral economisch/logistiek. Zeker voor een nucleair niet-geïntegreerde speler als Engie. In Frankrijk is het niet zo'n probleem als één reactor wat te veel of te weinig heeft gemoduleerd, de andere 55 vangen dat wel op. Hier zou dat big problemo zijn.

Goede opmerking! Dit zal idd ook meespelen denk ik.

D4T3 mogen 1% Pnom/min moduleren tot een minimum van 50% en 2h, kunnen dit om de 72h herhalen, en dit maximum 30 keren per brandstofcyclus van 18 maanden.
Hier is het dus geen modulatie, maar een grafiek die rekening houdt met im- en export (flow tracing).

Inderdaad: de grafiek is de flow traced energiemix, rekening houdende met im- en export. Als er bv. veel lokale opwekking is verdringt dit kernenergie wat, dit wordt dan geëxporteerd. Op andere momenten importeren we wat Nederlandse of Duitse kolenstroom.

Just a few years ago, it seemed implausible to run an energy system dominated by renewable energy. Even today, that narrative still pops up from time to time.
Yet we are doing it now. And tomorrow we will do it even better.

This stability has everything to do with the quality of the forecasts. Predicted and measured wind and solar production matched almost perfectly. Renewable energy may be intermittent, but it is not unpredictable. And we are getting better and better at it. /

Perhaps the most striking observation: the system imbalance rarely exceeded ±400 MW and the imbalance price fluctuated around €0/MWh for most of the time. In other words, the system maintained its frequency better than a Swiss clock. /

Electricity prices remained close to or below zero for most of the weekend, only rising late on Sunday (to a still acceptable level these days).
It is quite rare for prices to be so low for an entire day. This shows how quickly market dynamics are changing. /

Flow traced (taking into account imports and exports), Belgium's energy mix was:
• 🌬️ 69% renewable energy (mainly wind, some solar and bio)
• ☢️ 19.5% nuclear energy
• 🔥 6.2% fossil fuels (mainly gas)
• ❔ 5.3% other
(data: Live Electricity Maps) /

It may have escaped your attention, but the Belgian energy system has quietly passed an important test. During the weekend of 4-5 October 2025, our consumption was almost entirely covered by renewable energy. And yet the system ticked like a Swiss watch. /

(For the techies: for example, it appears that the OLTC (mechanical systems for voltage control on the secondary side) are not fast enough compared to inverter-connected production, which also has overly strict safety margins. By the time OLTC regulates down, inverters have already disconnected.)

The actual cause(s) are still being investigated (report in Q1-26). However, it seems clear that with production increasingly shifting to MV/LV level, the operation of the HV grid must also change. /

28 April Blackout in Spain and Portugal: Expert Panel releases comprehensive factual report

In particular, the tripping of a transformer station at 12:32:57 due to excessive voltage on the secondary side (cause still unknown), followed shortly afterwards by the tripping of two large PV installations at 12:33:16 (cause unknown), appears to have brought the system to its knees. /

The official ENTSO-E report on the Spanish blackout, released today, seems to confirm in detail what was already broadly known: a power surge event led to the shutdown of high-voltage lines and production units, plunging the peninsula into darkness in 30 seconds. 🧵

There's a severe shortage of gas turbines globally. Wait times have gone up from 2 years to 5 years or more. AI companies are willing to pay any price to get their hands on them.

Is that a climate blessing or curse? Our global investigation has an answer.

AI-Driven Demand for Gas Turbines Risks a New Energy Crunch

Orders for turbines to power natural gas plants are vastly outpacing supply, threatening the world’s ability to keep pace with rising electricity demand.

So: accelerate the roll-out of heat pumps, switch to electric cars, electrify industry. And yes, that will involve obligations. The alternative is to continue the current treading on the (moral) hamster wheel. It spins, but it doesn't get us any further. /fin

Just as a growing economy means more for everyone, accelerating the substitution of fossil fuels by electricity can make the challenge of producing that electricity more achievable. Because more demand means more room for all forms of sustainable production. 5/

That debate is full of complexities and wicked problems that are not helped by the simplistic arguments liberally thrown around by both sides. Complexities and problems for which there are no simple answers.
Except perhaps one: ‘Fix demand first.’ 4/

The (nuclear) energy debate is not about moral arguments or false dichotomies such as nuclear vs. renewable, but about how we organise our energy market, how we distribute investment risk, and where we draw the line between government and private initiative. 3/
