Vestas Invests in Crane for 200m+ Onshore Installations

Keyword: “Salamander Quick Lift”. One is reminded of the Lagerwey-technology, that also uses the wind tower as part of the crane. Wind tower installation minimalism in action.

UK Considering Highway Overhead Powerlines

Overhead power lines for trucks on the A5, south of Frankfurt.

Lorries powered by overhead electric cables could run on Britain’s motorways as part of a push to ‘decarbonise’ road freight. A trial scheme has been proposed for a 12-mile stretch of the M180 near Scunthorpe, Lincolnshire, which would receive £2million of government funding and could be operational by 2024.

Highway overhead power lines make perfect sense, not in the least because there will be no NIMBYs around, to protest against these stealth power lines, a major problem, especially in Germany. Also, from an energy efficiency point of view, this is excellent. Sending electricity from wind turbines or solar panels directly towards e-engines, can happen almost without losses. Trucks merely need small batteries to bridge the distance between warehouse and highway; no need for massive amount of charging stations either. All it takes is the electrification of the existing national highway system

Exploring Massless Energy Battery Breakthrough

What if we could take a battery pack’s weight out of the equation? Imagine a car that has no battery pack because the car’s structural battery is the pack? Let’s explore massless energy storage and how a recent breakthrough could be a dramatic shift in how we can store energy in phones, planes, cars… you name it.

US Order for 200 Swedish 19-Passenger e-Planes

Heart Aerospace Hangar in Gothenburg, Sweden.

Two US companies have ordered 100 battery e-planes each at the Swedish Heart Aerospace company. The planes could be operational by 2026.

Data: 19 passengers over 400 km. Charging time: less than 40 minutes. Battery: 600 kWh or 0.1 kWh/km/passenger. The author of “wattisduurzaam” fears this is too good to be true, but why not? A single person in a car “burns” a comparable 1 kWh on 10 km, so why can’t a small 19-person plane represent the equivalent of 19 cars? And then there is this:

[deepresource] – e-Genius Update

Data from 2015 and a 2-seater e-Genius plane, crossing the Alps at 4000 m: 365 km, 43 kWh. That’s 43/365/2 = 0.06 kWh/km/passenger. This German plane from 2015 has a better efficiency than the (bigger) Swedish plane.

A very simple, low-temperature Stirling engine. I have 2 identical ones of those, one for 30 euro from Amazon, the other one from Banggood for 10 euro. The latter actually works, the quality greatly varies. Great tool to impress your colleagues with a cup of hot coffee as heat source, which makes it run for more than 30 minutes.

45 GW Wind/Solar/Hydrogen for Kazakhstan?

Artist impression from the developers site

It sounds a little too Wild West, or Wild East rather, but the company Svevind AB (Swedish? German?) has announced it has signed a memorandum of understanding with a Kazakh investment firm about developing a 45 GW wind and solar farm, combined with 30 GW hydrogen capacity in Western and Central Kazakhstan. Cost and commissioning date are vague:

The overall development, engineering, procurement and financing phases are expected to take about three to five years. Construction and commissioning phases are predicted to take approx. five years.

About Svevind:

Svevind is a privately owned group of companies in the renewable energy industry, based in Weißenbrunn (Germany), Piteå (Northern Sweden), Dresden (Germany) and Almaty (Kazakhstan). The Svevind group plans, develops, designs, sells, and operates onshore wind power and solar PV as well as green hydrogen projects. The projects vary in size and scope from single turbines to farms of 1,101* turbines and up to Gigawatt-scale green hydrogen projects. Svevind’s largest project to date is located in Markbygden in the municipality of Piteå. It is expected to become one of the largest wind farms in Europe, and perhaps the world. Total production is expected to be up to 12 TWh.

[svevind.se]

The story could win in plausibility if it could be shown that the project has Chinese financial backing. So far, Svevind has realized 1 GW wind power and 1.5 GW under construction.

Grain of salt.

Northvolt Increases Battery Production Target to 60 GWh

The car battery market is demand-driven. Manufacturers hardly can keep up with demand, a situation comparable to the microchip market. This encouraged Swedish battery producer Northvolt to increase its production target from 40 to 60 GWh annually.

The company has zero problems to attract capital from the likes of the BMW Group, Volkswagen Group, Goldman Sachs, Folksam and the European Investment Bank. Northvolt is seen as the European answer to Tesla. The plant in Skellefteå, northern Sweden will start production later this year and enjoys a VW order pipeline to the tune of $14bn. Northvolt is building a second factory in Salzgitter, Germany, and will probably start production in 2023–2024.

Chalmers University Announces Breakthrough Massless Batteries

Researchers from Chalmers University of Technology have produced a structural battery that performs ten times better than all previous versions. It contains carbon fibre that serves simultaneously as an electrode, conductor, and load-bearing material. Their latest research breakthrough paves the way for essentially ’massless’ energy storage in vehicles and other technology.

Translation: the car itself is becoming the battery.

Current energy density: 24 Wh/kg or 20% of Li-ion
Expected energy density: 75 Wh/kg (separate project SNSA)

Building a car from carbon fibre gives it the same strength as aluminum, but the material has 50% less weight, lowering the required electrical energy per kilometer.

Here the Audi A2, a less than 900 kg car, made from aluminum. Yours faithfully once had one himself (33 km/l diesel or 78 mpg).

Funding: European Commission’s R&D program Clean Sky II and USAF.

Apparently there exists a deal with Norwegian Haugaland Kraft that IF SeaTwirl installs the S2, Norway will buy the electricity. Probably nobody is willing to fund the project as yet. The Haugasund locations has been identified as suitable for installation of the S2.

They do have EU support:

How to Manufacture a Crib Entirely Fossil-Free

Long version, mixed Dutch/English language.

There are many renewable energy skeptics who claim that a renewable energy base won’t work, because, you see, “renewable energy is an extension of fossil fuel“. Vattenfal-Nederland showed that it is already possible to produce a child’s crib and mattress, entirely without fossil fuel. Paint from potatoes, transport by sail boat and e-vehicle, all machines are electric, steel produced with electricity. The cloth for the mattress is still made by hand. No cotton from abroad, but from locally-grown linen. The mattress filling was made from sheep wool, that had to come from the island of Texel. Use of the natural-gas powered ferry was out of the question, hence the sailing boat.

Vattenfall has the slogan “fossil-free within one generation“. And the first think the next generation will need is a crib.

Short Version.

Movdion Produces 110m Wind Towers Made of Wood

The Swedish company Modvion has installed its first wind tower made from laminated wood on the island of Björkö outside Gothenburg. The tower has a height of 30m.

The highest existing wooden tower in the world has a height of 118m, the infamous Gliwice transmitter tower in Poland, built in 1935, that gained some notoriety in the outbreak of WW2.

Modvion wants to break the record and build a laminated wooden tower of 110m high, carrying a wind rotor, that will lead to a structure of 150m in total. The energy company Varberg Energi will buy and install the first exemplar.

Hydrogen Perfect Fossil Fuel Replacement in Steel production

Dang, yet another nail in the coffin of those who claim that renewable energy is an extension of fossil fuel, where in reality it is a fossil fuel killer. The Swedish steel producer Ovako and partner Linde Gas AB has successfully completed a test run where they managed to produce steel with hydrogen. The quality of the end-product was the same as traditional produced steel.
