Yesterday was our official NEONreseach.nl KICK-OFF!

tagline: NEON 'lights the way to zero emission energy and mobility'

Here are 5 PhD positions on the program.

Apply if they appeal to you and you want to work in a multi-disciplinary team (thread) Image
vacancy A: NEON research: Energy demand and new market models
jobs.tue.nl/en/vacancy/the… Image
vacancy B: NEON research: Technical standards to accelerate the energy transition
jobs.tue.nl/nl/vacature/th… Image
vacancy C: NEON research: Modeling the energy and mobility transition (2 positions)
jobs.tue.nl/nl/vacature/th… Image
vacancy D: NEON research: Modeling climate impacts
jobs.tue.nl/nl/vacature/th… Image
Please read the website carefully and use the website to apply. Please don't use email since your application might get lost and it is a lot of extra work for us. But you can ask me/us questions using email (see site). Image
NEON research accelerates the energy transition with a focus on solar, wind, electric mobility, MAAS and smart grids and using a team with many different competencies that will work closely together with each other and with companies and governments.

Every Friday we come together in Eindhoven (virtually for now) to learn from each other and motivate each other. We end the week / start the weekend with music and drinks.

Most important are the 35 PhDs.

They work closely with the principal investigators
neonresearch.nl/team/ Image
But of course people of the 20 partner companies are also welcome and every month the Friday is a mini-conference with presentation to and from partners.

The idea is also to use these presentations to eventually create a global transition course.
neonresearch.nl/partners/ Image
Every year we produce a report and (more importantly) an online model that shows cost effective pathways to a renewable future. At the kick-off a member of the Dutch parliament already indicated that he and his colleagues would LOVE to use that.
Let's not exaggerate: a lot of the practical work within NEON will still be writing papers that are primarily relevant for a specific domain or discipline. But the explicit purpose is that the PhDs together create societally relevant pathways that accelerate the transition.
That's the kind of "purpose driven movement" you would become part of when you get a PhD position within NEON. And we aim to grow further so we can make a BIG difference! Please apply when that appeals to you!
And usually I don't spam on Twitter but it is *really* important that we find the smartest and most motivated people for NEON.

So I would like the tagged & following people to consider a retweet. (You can simply mute this discussion if you don't want to see notifications!) Image

Just made a visualization for myself about the unprecedented growth in solar that I thought I might share.

From 1880 to 1950 all electricity came from fossil+hydro. Then nuclear briefly grew with market share increasing with up to 1% per year in 1985.

Now solar takes over. Image
I've described in more detail in a substack post:

There's more info on each picture there.aukehoekstra.substack.com/p/the-coming-s…
I made this picture because I think you forget what is happening when you look at total final energy. Renewables seem so tiny! Image

I see this a lot:

Conservatives who *just know* that nuclear is better than solar and thus blame their favorite scapegoat *the government* for solar doing better.

But in reality it's the opposite: the market likes solar so much that not even the government can save nuclear.
I guess Andre's attention for me is due to my being irritated at his fact free diatribes of pseudo-scientific nonsense:


So now he sees reacting to me as a way to get attention?
And I'm reacting again, so maybe I'm being duped?
Anyhow...
Let's start with some quantifiable facts. (Things this conservative armchair energy philosopher is allergic to.)
First thing we notice is that solar and wind are clearly surpassing nuclear (though the new leadership of the department of energy denies it).

Many people think solar and wind won't be able to keep the grid stable because they lack "inertia".

I think solar, wind and batteries will do a BETTER job and I think you can explain it thus:
- the old grid is a record player
- the new grid a digital player
🧵 Image
If you play vinyl records, the rotating mass of the turntable is used to keep the speed steady. This leads some vinyl enthusiasts to seek more mass because that will keep things more steady.

This turntable by Excel audio attaches a separate mass. (Overkill but makes my point.) Image
In the same way the inertia in the rotors of current power plants helps the grid to keep a steady 50 Hz (in e.g. Europe) or 60 Hz (in e.g. the US) frequency.

These machines turn a heavy copper coil wound around a heavy iron core and this helps keep the grid frequency steady. Image

Great to see more and more attention for flexible grid pricing.

We must say goodbye to the "copper plate" that offers free power everywhere and every time. It's hideously expensive and outdated.

What we need is smart flexibility.
🧵
The underlying reason is that the costs of different components of the energy system changed:

Some remained high (e.g. pylons, fossil & nuclear)

Some plummeted (e.g. solar, wind, batteries, EVs & inverters)

Some became possible at all (e.g. measuring & steering in real time)
So now we should make good use of these new, clean, abundant and affordable options, even if it means doing things a bit differently than before.

So what should we do different regarding grid congestion pricing?

Some are angry about the "anti-Christian depiction of the last supper" at the Olympic Opening ceremony. (@elonmusk and @realDonaldTrump among others)

A Dutch art historian explains it's not the last supper but a Dutch painting of the Olympic gods.
And I explain what I loved.

Original Dutch thread here. I just translated it.


@WSchoonenberg shows that the "tableau vivant" (living painting) is depicting "The Feast of the Gods" by Jan van Bijlert, from 1635.
Image
The heathen Gods have gathered on mount Olympus for a feast. Sun god Apollo is recognizable by his halo, Bacchus (Dionysus) by the grapes, Neptune (Poseidon) by his trident, Diana (Artemis) by the moon, Venus (Aphrodite) by Cupid.

With new batteries solar and wind are not only faster and cleaner, but also cheaper.

I'm estimating:
$0.08/kWh for PV+batteries
$0.07/kWh for wind+batteries

@skorusARK gives a good overview of current wisdom, but strongly declining battery prices change EVERYTHING
Image
I've recently written about how I was surprised I missed the enormous consequences of price reductions in batteries.

LFP cells are now $50/kWh and last 10 000 cycles.
That's $0.005 per kWh.

Say we double that to pack the cells and you are at $0.01/kWh.aukehoekstra.substack.com/p/batteries-ho…
If you add batteries to solar PV, not all energy has to flow through batteries. But let's keep it at $0.01 and add that to the price of solar. That makes PV (and wind) SUPER cheap!

Batteries must be discounted more quickly you say?
