A changed energy culture - High voltage direct current HVDC

If we are to get the full benefit of High voltage direct current HVDC Green BATTERY El/Hydrogen 6.4 GW 800KV HVDC "ELECTRICITY and HYDROGEN BATTERY", - Then we must rationalize with the "distance" in a sensible and more modern way.

With this method. The distance from supplier to consumer is "always" reduced to the geographically shortest.

Example:

We know that the total energy loss in our outdated grid is approx. 40%, you may not think about it, - about 6% is direct loss in the cable from supplier to consumer, but today we use alternating current and to correct for the 6% loss in the network (the household will not pay for it), - we transform current and voltage up and down several times before "All customers" get exactly 230V 16A delivered to the meter.
Regardless of the distance to the supplier.

- - it is very expensive, and costs in resistance and heat generation approx. 40%, absolutely crazy.

Now you know, - - so imagine that Helsingør has just installed a 30KW electric boiler for district heating and is in the process of establishing 2 X 50MW Seawater Heat Pumps with a COP value of Approx. 3.6 for replacing/phasing out the wood chip boiler.

If the two large consumers are connected directly to the new "DC ELECTRICITY and HYDROGEN BATTERY" infrastructure, then the two consumers would "draw DC power directly from "THE BATTERY" - which will always find the shortest distance to Hesselø, and the citizens of Helsingør will in principle be able to save 35% on their heating bills.

In Helsingør, we can further relieve Lynetteholmen with a cruise terminal with shore power - Methanol and hydrogen directly from the High voltage direct current HVDC Green BATTERY El/Hydrogen 6.4 GW 800KV HVDC "ELECTRICITY and HYDROGEN BATTERY"

Furthermore, we could offer Maersk to refuel the new container ships directly from Helsingør's new cruise terminal with Methanol (Traditionally, green methanol is produced from CO2 by adding hydrogen, which is delivered to the cruise terminal in Helsingør directly from "THE High voltage direct current HVDC BATTERY", together with shore power.)

The High voltage direct current HVDC BATTERY can also be supplied/supplemented with a direct methanol pipeline

Kastrup Airport and Lynetteholmen can also go directly to "THE High voltage direct current HVDC BATTERY"

Example II

Alborg Portland is the country's largest electricity consumer and Aalborg has ordered a 120MW Seawater heat pump
- - if both are connected directly to the new "ELECTRICITY and HYDROGEN BATTERY" infrastructure, then Aalborg would draw energy from Skagen or Læsø and Aalborg's district heating customers would save 30% on heat and Portland would get 20% more profit on cement.

We have many other heating plants and industry, which with an advantage of 20 -30% on electricity costs, can be connected directly to HVDCBATTERY.com El/Hydrogen 6.4 GW 800KV "ELECTRICITY and HYDROGEN BATTERY"

We must rationalize with common sense the consumption of the expensive AC power and Trans-format less current and voltage up and down several times before the customer gets exactly 230V 16A AC power delivered to the meter.

This description only concerns the "BATTERY" function itself, which only triggers a smaller part of the "gain" of a modern Hydrogen - EL - Ptx energy infrastructure in 2025, which is also prepared for a -253°C. cooled superconductor where 50 X Cheaper "Iron" becomes a better superconductor than copper or aluminum.
(Sounds crazy, but nice to know now when Trump wants the copper mines in Greenland)

When you read this, you probably don't believe that the energy loss is so severe in the Danish electricity grid, but examine it and breathe twice, - - - -

Is it possible to establish an energy infrastructure that functions as a mega BATTERY throughout the entire geographical extent? ?
”Just plug in and connect” - - Sounds crazy but --- Yes today it is possible.

- - Denmark has the technological background and - - well - - Know – how - - lies in a well-developed Software on the new AI algorithm.

IF I have and can deliver the method for the described El/Hydrogen 6.4 GW 800KV HVDC ELECTRIC and "HYDROGEN BATTERY" and Denmark can thereby raise its GDP by more than 10% Annually and all patents on this, are shared in a Danish industry collaboration? ? - -

Isn't that exactly what we are missing? - in a new competition-oriented world order. - -

Would that change the world and Denmarks competitive situation. ? –
all other countries have greater energy losses,
but there are much, much greater savings by saving up and down transformation
– Read the two examples. - - - there are thousands and gastronomically many billions to save.

Tenne T Germany could handle the entire task. - - But Tenne T is working on a 5GW HVDC down through Germany "Suid Link"

With a capacity of 98 MW/196 MWh, the Pillswood plant in Cottingham, UK, will be one of the largest Batteries in operation in Europe from 2022.
Pillswood has enough power to supply energy to more than 300,000 British households for two hours

Danish HVDCBATTERY.com El/Hydrogen 6.4 GW 800KV HVDC "ELECTRICITY and HYDROGEN BATTERY" - - has no time horizon but will continue for weeks, as long as there is sufficient hydrogen in the buffer.
That is up to us.

The illustration below is very simplified, but just to illustrate that if Helsingør establishes 2 X 50 MW seawater heat pumps, they will draw power the shortest way, from Hesselø, while Portland cement and Aalborg's 120MW seawater heat pump draws power from Skagen and Læsø.
This saves energy loss over distance.

Not sufficient in the long term:

Even in the long term, a 6.4GW 800KV energy infrastructure will not be sufficient, but we will "split" both the new DC and the old AC structure into the same modules.

We select the large consumers where it will be most appropriate to offer a direct DC connection.

For example, the two examples will work much better on a direct DC current, whereas lights and hand tools in ordinary homes work better with 230V alternating current as we know it.

Therefore, we create one or more "Converter stations HVDC to HVAC - Voltage Sourced Converter VSC" - for each geographical module.

This allows us to give the "Large Consumer" (the two examples) plenty of time to consider the benefits and disadvantages of DC (”Direct Current”) or AC (”Alternating Current”), and the private consumer only experiences the 10 minutes it takes to switch from Old to new energy infrastructure

If a patent or several are to remain in Danish hands and benefit DI, there must be 6 - 8 "LARGE" Danish companies that can collaborate on the task in confidentiality.

The need for energy storage

When we phase out fossil fuels, we in Denmark will need a terrawatt hour (TWh) large energy storage to get through the winter. With TWh hours we are talking about a capacity that corresponds to double-digit millions of car batteries, - - -something we cannot solve with ordinary batteries. That kind of capacity can almost only be provided by cavern-based gas storage in the underground - for example, Denmarks natural gas storage is ~12 TWh.

Today - May 2025 we have solved the problem - - HVDCBATTERY.com has solved the problem

Energistyrelsen has launched on 20 November tenders for:

Denmark just opened 2.8 GW of new offshore wind… but what does that actually mean? 🤔⚡️
🔹 North Sea Mid- minimum 1 GW
🔹 North Sea South- minimum 1 GW
🔹 Hesselø (Kattegat)- minimum 0.8 GW
Plus: developers are allowed to over-plant, so the final capacity could be even higher 🌬️
