Self-Climbing Crane Making Progress

The idea is to substantially cut cost installing a wind turbine by using the turbine itself as a crane. The first (positive) experiences are now in with the construction of a 4.5 MW turbine. Large cranes are no longer necessary anymore.

Bill Gates with DOE into Mini Molten Salt Reactors

[source]

The Energy Department is participating in major push with electric utility Southern and a company founded by Microsoft founder Bill Gates to develop small nuclear power reactors that are less expensive and more efficient than their much larger cousins.

“Molten salt reactors are getting a reboot,” the Energy Department tweeted late Wednesday, offering a schematic of a battery-like power plant module that “could power America’s energy.”

Investment volume: 20 + 28 million $.
Prototype expected by 2030.

Concrete Battery

Swiss startup Energy Vault wants to lift concrete weights (density 2.4 ton/m3) to store renewable energy when there is no pumped hydro as alternative, currently 96% of the world’s energy storage capacity, with 75% of it in 10 suitable countries only.

The idea: 120 m crane lifting 35 ton of concrete blocks and pile them up neatly. Storage capacity 20 MWh, sufficient for 2,000 household-days. Round-trip efficiency 85%. The lifting and positioning is done automatically, no human intervention necessary, thanks to camera’s and software. The system is relatively insensitive to wind, software compensates for it. The idea is to use building waste, municipalities otherwise pay money for to get rid off.

Currently a demo site with 20 m crane and 500 kg blocks is in operation.
Storage cost:

Lithium-ion: $280-350/kWh
Concrete battery: $150/kWh

First commercial projects are said to be realized early 2019.

The Sudden Death of Peak Oil – 4.5 Trillion Barrels of Oil Left

Google trends – nobody is interested anymore in the topic of “peak oil”

Technology is not just expanding our daily oil production; it also continues to increase the amount of oil and liquid fuels we can count on for the future.

In 1981, the U.S. Geological Survey estimated that remaining global recoverable crude and condensate resources were 1 trillion barrels; today, the IEA estimates that it is 4.5 trillion barrels – enough to meet global oil demand beyond the 21st century. By 2040, the amount of resources yet to be produced will still be far higher than total production prior to 2040, even with a 20 percent rise in global oil demand.


Oil reserves according to the IEA and US Geological Survey: 4.5 trillion barrel of recoverable oil left, that would be 27 times the largest oil field in history, Ghawar.

Note that the IEA doesn’t state at what price levels these 4.5 trillion barrel can be recovered. Regardless, there is enough oil left to set up a renewable energy base. The challenge is not to find new oil, the challenge is not to use it.

Nord Stream 2

With 1,222 km the longest sub-sea pipeline in the world. The US are against building Nord Stream 2, but 66% of the German population wants to see the pipeline build. Construction of Nord Stream 2 began in May 2018. The project is expected to be completed by the end of 2019.

Nord Stream I = 55 billion m3/year
Nord Stream II = 55 billion m3/year

That’s an amount of energy of 110 billion m3 gas = 1100 billion kWh or 1100 billion / 0.5 billion Europeans = 2200 kWh per European per year.

Rationale: supply security, read become independent from unreliable overland intermediaries like the Ukraine.

Microlino

If you realize that the average occupation rate of your standard sedan is ca. 1.25 persons, meaning that a car mindlessly mainly moves 3.75 empty seats around… if you additionally realize that in a carbon-starved world, not because we run out of carbon but rather that we running into limits of the amount of carbon the atmosphere can handle, we cannot continue with our old ways… if you also realize that a car is mainly used for single person commuting (in Holland on average 34 km/day), shopping and business travel and not for happy families of 5 travelling to the seaside with dad-knows-best behind the steering wheel and mum distributing the sandwiches… these three realizations should really cause car designers to rethink traditional personal transportation assumptions.

Enter the Swiss-made Microlino:

Battery: 8 kWh or 14.4 kWh
Acceleration (0-50 km/h): 5 seconds
Range: 120 km or 215 km (with 14.4 kWh battery)
Maximum speed: 90 km/h
Price: 12,000 euros
Market-ready: 2019

Note: this could be the solution for those happy few who still will own a car. For the lesser Gods, the self-driving shared van could be the future.

Battolyser – 90% Storage Efficiency With Combining Batteries and Electrolysis

[source]

The idea: combining battery and hydrogen-production functionality in one device. Battery + electrolysis: battolyser. Players: Technical University Delft and Proton Ventures from Schiedam, Netherlands. The battery is Thomas Edison patented technology from 1901. The production of hydrogen was so far an unwanted side effect during charging of the battery. Researchers now want to turn this bug into a feature. The production of hydrogen begins when the battery is as good as fully charged. It is this combination that leads to an excellent overall storage efficiency of 90%. All you need is abundant available zinc, iron and water.

First experiments early 2019 with a 15 kWh prototype, but the university, energy giant Nuon and Proton are already thinking aloud about a 10 MW model

[wattisduurzaam.nl] – Hoe deze antieke accu uit Delft oneindig veel windenergie opslaat
[pubs.rsc.org] – Efficient electricity storage with a battolyser, an integrated Ni–Fe battery and electrolyser

Our results demonstrate a remarkable constant and a high overall energy efficiency (80–90%), enhanced electrode storage density, fast current switching capabilities, and a general stable performance. The battolyser may enable efficient and robust short-term electricity storage and long-term electricity storage through production of hydrogen as a fuel and feedstock within a single, scalable, abundant element based device.

Developments in Growing Food in an Age of Climate Change

Scientists in the Netherlands say they are close to a breakthrough which will allow crops to be grown in deserts. Many say this could completely alter life on the African continent and even end hunger. World leaders meeting at the climate talks in Germany are being urged to commit to more funding for new agricultural projects in drought-stricken parts of the world.

  • productivity: 900 head of lettuce per m2 (200 kg). Any other crop will do as well.
  • 1 hectare (100m x 100m): 4 workers, mainly supervising. Planting, watering, harvesting, packaging, all automated
  • production: around the year, completely planned, meaning little necessity for storage. Straight from the “field” to the super market
  • these production facilities can be build next to Amsterdam, Stoke-on-Trent, Johannesburg, Riaydh, Reykjavik, anywhere. Almost complete independence from environmental conditions
  • almost no transportation cost: production next to consumers
  • lights from leds doesn’t take that much energy. And if you don’t stack, you can let in sunlight (Summer)
  • Water requirements: near zero. All water remains in the building, apart from the small quantities embedded in the product
