Electronics nerd, Audio systems geek, great interest in fossil-free energy supply.

Doing odd stuff: Helped renovate an old fortress at sea, for scouting. Hard and fun!
Som supplement, blev Aalborg Portlands projektleder samt direktøren interviewet i september 2025: open.spotify.com/episode/3BR9...
De fortæller om den nuværende produktion og deres planer for at udskille CO2, deres valg mellem at bruge mere brændsel (der giver mere røggas at behandle) eller mere el.

@strategicperspectives.eu put out a nice analysis last week showing how electrification gets us off US gas in 10 years and off all imported gas except for Norway and the UK by 2040.

Når 'Green Power Denmark' kalder projektet "banebrydende", troede jeg, at det drejer sig om ny teknik, og vise, at de udtænkte løsningsforslag virker i praksis.

Mon @greenpowerdenmark.dk kan uddybe?

Hmm.
Hvor ser man 2 eller flere HVDC-linjer koblet til et knudepunkt, sammen med en række vindturbiner?
(Eller "multi-terminal HVDC".)

Er der andre HVDC-net (ikke bare linjer), der når at blive sat i drift, før Energiø Bornholm kan blive bygget?

Er det rigtig forstået, at argumenterne for Energi-ø-projektet med 3 vindfarme og et el-knudepunkt på Bornholm, handler om at lave
* en redundant el-forbindelse til Bornholm
* en ny linje mellem Sjælland og Tyskland
* udvikling og demonstration af et knudepunkt med flere HVDC-linjer
?

Which helps reduce the consumption of 'natural gas' (together with new wind farms and solar PV), which help reduce the need to import methane (when consumption falls faster than the production fades out).

The two right-most columns are 2 parts of one scenario.
The different height of the red boxes are because of "8% line losses".
Transferring electricity through the wires of the power grid, heat them up a bit, giving some losses. It is necessary to generate more in one end, than used in the other.

New Sanctions On Russian Oil Hit Indian, Turkish Refineries. Enter China?
New sanctions will ban imports to the EU of products derived from Russian oil from January 21. But critics point to enforcement loopholes and also warn that Chinese ‘teapot’ refineries may be picking ...

Slowly the consumption of diesel and petrol will fall in Europe, as businesses and peple slowly turn away from vehicles with combustion engines.

Freight companies sees a lot of cases, where it is cheaper to buy and operate an electric truck compared to a diesel version, over the life of the truck.

Er det en aflednings-manøvre, som USA's regering er i gang med?

Er der noget andet, som USA's regering absolut ønsker at vi skal opdaget?

Det er en meget absurd forestilling.

Getting running costs lower than diesel with high probability, is important for freight/transport.
A sound choice for those who can make long term investments, charge at the depot, and perhaps supplement with a solar system at the depot and a 'power purchase agreement' for cheap renewable energy.

Does anyone have a rough idea of how many destillation columns, the key part of refineries, which is hard to replace, that are still working in Russia?
January 12, 2026 at 2:02 PM
Putin will probably not like it, when the purchase of methane gas (natural gas) goes down in Europe, reducing reliance of imports.
:-)
Hope people will realise how well a properly installed heat pump can work.

Are the realistic guesses regarding how much economic setback the influential and rich people in Russia will accept, before the existing mix of protection schemes and corrupt deals becomes unimportant to them?

Creating new business/jobs/activity in the mining regions should get top priority.

If mining companies are about to go bankrupt, it is very unhelpful that politicians shout "coal is cheap", but does not seek to *change* the situation.

People needs options for jobs that can sustain their living.

Main points:

- reaching climate neutrality will mean managing our limited sustainable biomass resource carefully
- we need to think not just about energy efficiency, but also carbon efficiency (how well we use biogenic carbon)

Over a whole year, the generation from solar reduces the consumption of methane gas by a lot.
The cost to generate electricity gets reduced, overall.

Even though solar generation is minute some days, it is still very useful over the years.

Russia cannot raise the price of the electricity from PV.

As people with gas boilers typically buy much more energy as gas than electricity, the *proportions* of a shift could look like a 5 p/kWh reduction on electricity and just 1 p/kWh on methane added.
December 3, 2025 at 10:16 PM
All households use some amount of electricity, so if the levy on electricity is reduced, every household will save some money, which can then be used for a levy on gas.

Shifting levies will make the transition easier, without messing with the cost of living, if done right.
