German Grid Still Reliable Despite Growing Renewable Energy

Despite a growing share of renewable energy in Germany, the grid remains as stable as ever: the average German has on average to endure a 11.5 minute/year blackout. Although grid stability will become an increasing challenge, for the moment everything is still fine.

French Oil Giant Total Into Renewable Electricity

French oil giant Total follows in the footsteps of that other European oil major Shell, in betting on the success of renewable energy. This is no doubt influenced by the radical choice for renewable energy by the European Union, that wants to get rid of fossil fuel in Europe by 2050.

Ubitricity Has a Cheaper Method of Charging E-Vehicles

[source] The new way to charge e-vehicles?

The large-scale introduction of e-vehicles could very well imply the need for large-scale electricity charging stations along the way-side, like this situation in Berlin:

[source]

This could become quite costly, not to mention endless amounts of ugly car-chargers littering the streets of the near future.

The German company Ubitricity has come up with an idea to reuse old lampposts to achieve the same charging performance, but much cheaper and no impact for the way streets look like.

But nothing has decided yet as there are other methods in the works to recharge you e-vehicle… instantaneous at the pump, as usual!

[deepresource] – IFBattery – Instantaneous Recharging Batteries

And the Winner of the E-Vehicle Transition is… Norway!

Norway is ahead of everybody else in its ambition to get rid of the stinking petrol clunker once and for all. In 2017 the majority of new vehicles sold in Norway are e-vehicles. By 2025 all vehicles sold should be electric by law.

Why Norway? Because of government regulations and the convenient fact that Norway has a lot of hydro-power, the easiest form of renewable energy around, which ensures that e-driving is really clean and not a zero-sum game of moving emissions from a car exhaust to the fossil power station smoke stack.

And as the Dutch proverb goes: “if one (Norwegian) sheep has crossed the dam, more will follow.”

Like the Netherlands for instance. The flatlanders have no hydro-power worth mentioning, but ambitious offshore wind park plans, to be realized before 2023, providing enough electricity from wind to power an entire Dutch e-vehicle fleet. Like Norway, the Netherlands wants to phase out petrol cars after 2025.

Bloomberg – Peak CO2 Emission from Power Generation in 2026

CO2 emissions from power generation will peak in 2026, and be 4% lower in 2040 than they were last year, according to a new report by Bloomberg New Energy Finance (BNEF). Much of this will be due to “unstoppable” renewable energy sources undercutting the majority of existing fossil fuel power stations, with the cost of solar dropping 66% by 2040, and onshore wind by 47%.

European Power Grid

[source] Overview border-crossing power exchanges.

In 2007, the EU was importing 82% of its oil and 57% of its gas, which then made it the world’s leading importer of these fuels. Russia, Canada, Australia, Niger and Kazakhstan were the five largest suppliers of nuclear materials to the EU, supplying more than 75% of the total needs in 2009. In 2015, the EU imports 53% of the energy it consumes.

The European Union has a decarbonisation policy that aims at phasing out most fossil fuels by 2050 (original goal: 95% cut from 1990 levels). Purpose: minimization climate change and help keeping global warming under 2 °C.

[wikipedia.org] – Energy policy of the European Union

[source/pdf]

Renewable energy sources, that are supposed to replace fossil fuel, are notoriously intermittent. This requires a continental grid where large amounts of energy can be transported from one country to another. In 2002 the EU decided that by 2020 every member state should be able to acquire at least 10% of its electricity needs from neighboring states. Currently 22 out of 28 EU member states are on track, c.q. have already achieved that aim.

[energypost.eu] – The Great Grid Special: where is Europe going with its grids?

In the 2014 the EU proposed to extend the 2020-10% target to 2030-15%:

[ec.europa.eu] – Electricity interconnection targets
[ec.europa.eu] – Commission launches new electricity interconnection targets expert group

Long distance electricity transport over thousands of kilometers is extremely cheap and efficient, with costs of US$ 0.005–0.02 / kWh. As of 1980, the longest cost-effective distance for direct-current transmission was determined to be 7,000 kilometres (4,300 miles). The consequence is that it is possible to contemplate the design of intercontinental grids, where offshore wind energy from Northern Europe (North Sea, Irish Sea and Baltic) can be combined with abundant solar energy from Northern Africa, the Sahara and even Saudi-Arabia (ignoring political aspects).

[wikipedia.org] – Electric power transmission

It is these kind of considerations that have led to the idea of the “European Super Grid”

Including Northern Africa into a European Supergrid. Technically feasible, but politically sensitive.

New Record Siemens Electric Airplane

Speed record for an electric aircraft. Motor 50 kg and 260 kW, plane weight 1 ton. Top speed 340 kmh, flying a distance of 3 km on March 24, earlier this year.
Electric flying can be done more energy efficient than with flying on fuel.
Siemens believes that hybrid-technology offers the most promise: fuel for climbing and electricity for cruising. Siemens is cooperating with Airbus to get a proof of concept for a hybrid aircraft by 2020 for the short range: 100 passengers 1,000 km.

Hermes Eindhoven Realizes 1,000,000 KM All-Electric

Nice and quiet and clean. After 2025 sales of new cars driving on fossil fuel will be prohibited and the old ones phased out largely by 2032. The Netherlands will be a silent place, much more than today.

On 18 April 2017, Dutch passenger transport company Hermes reached the milestone of 1,000,000 kilometres travelled with the 43 electric buses that have been in service since last December. The fully electric VDL Citeas, with their futuristic design, are now a common sight in Eindhoven. The drivers operate the buses on eight different zero emission routes with due pride. The electric operation is now operating at full capacity, with the buses clocking up over 9,000 km every weekday. Several buses even cover more than 340 km per day on their own.

Dutch Post-War Electricity Production

nl-electricity-production

Studying this graph could give cause to a somewhat relaxed attitude regarding doom stories related to a so-called “energy crisis”. The kicker: in 1945 there was hardly any electricity production in the Netherlands worth mentioning. If you project the current level of “decentral” generated electricity (wind, solar, bio, hydro, etc. and fossil based electricity and heat production by private parties other than power stations) onto the past, you arrive at 1970. Life was already pretty good in those days. There is no reason to assume that society would break down if for some reason electricity production would be reduced substantially.

nl-electricity-production-source

Not to give the impression that “decentral” is the same as “renewable” (dark blue). It isn’t and there is no reason to be complacent. But once these offshore wind GWs are installed after 2030 there is no reason to despair with the Dutch energy situation as far as electricity is concerned. Space heating is a different story. Solution approach: seasonal storage of solar heat and most of all geothermal.

Construction Started COBRA Cable Netherlands-Denmark

COBRAcable (COpenhagen-BRussels-Amsterdam cable) is a planned 320 kV, 700 MW HVDC submarine power cable between Eemshaven, the Netherlands, and Endrup near Esbjerg, Denmark.

The cable will have a length of 325–350 km, and will be jointly owned by Energinet.dk and TenneT. Its purpose is to improve the European transmission grid and thus to increase the amount of variable wind power in the energy mix while improving the supply security. Its 700 MW capacity corresponds to an annual transmission capacity of 6.1 TWh

[wikipedia.org] – COBRAcable

The capacity of the cable, to be completed in 2019, would be sufficient to power a city like Amsterdam. The construction of the cable is a natural part of the strategy to move towards more renewable energy and the necessity to even out intermittent supply.

Germany Electricity 2015 – 33% Renewable

lower-saxony-wind[source] Lower-Saxony, Germany

Some good news from Germany for a change: in 2015 the country will generate 33% of its electricity from renewable sources. This is up from 27% last year, a massive increase. At this growth rate, Germany could generate electricity 100% renewable by 2027.

Total amount of renewable generated electricity: 193 billion kwh or 55 billion euro against end consumer prices (28.8 cent/kwh).

On Saturday July 25, 2015, 78% of Germany’s electricity needs were covered by renewable sources, a new record.

Wireless Electricity

Japanese scientists have made a breakthrough step towards developing new energy source for humans in the future by for the first time transmitting electric power wirelessly to a pinpoint target using microwaves.

Japanese scientists from the Japan Aerospace Exploration Agency (JAXA) have succeeded using microwaves to deliver 1.8 kilowatts of power through the air to a pinpoint target 55 meters away, a spokesman for the agency said.

“This was the first time anyone has managed to send a high output of nearly two kilowatts of electric power via microwaves to a small target, using a delicate directivity control device,” he said as quoted by AFP on Thursday.
