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.

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.

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.

European Supergrid Submarine Cables – Inventory & Plans

Subsea-Power-Cables[source]
An essential part of the solution to Europe’s energy problems is the European Supergrid. It means that all European countries will be interconnected to even out demand and supply patterns. Most countries in continental Europe are already strongly interconnected. A missing link though are connections to the country that could serve as ‘Europe’s battery pack‘: Norway.

Iceland is considering building the world’s longest subsea power cable by around 2020 to take advantage of its abundant geothermal energy to supply Britain with green power, the head of the state-run electricity producer said. “We can serve as a green battery for the U.K.,” Hordur Arnarson, the chief executive of Landsvirkjun said in an interview… Landsvirkjun expects to make a final investment decision on the 1,000 kilometre subsea cable by 2015-2016… McKinsey & Co. estimates it (Iceland) is harnessing only 20 to 25 per cent of its hydro and geothermal energy potential… Mr. Arnarson declined to cite a figure for the costs of construction, which would take five years and would entail laying cable 3,000 metres underwater in some areas. The longest subsea cable currently in operation is the 580-kilometre NorNed link from Norway to the Netherlands, which was completed in 2008 and cost €600-million ($784-million U.S.).

[theglobeandmail.com] – Iceland revives plans for world’s longest subsea power cable, Jan 9, 2013.

Israel-Cyprus-Crete-Greece
Now even Israel wants to get connected to Europe (Greece), to start with Cyprus.
The cable’s total length measures 870km (540 miles) and its depth is over 2,000 meters (656 feet). Between Israel and Cyprus, the cable will be 270km long. Electricity will flow in both directions at a capacity of up to 2,000MW. Another cable will connect Cyprus and Crete which forms part of the Greek electricity grid. As a result, Israel will be connected to the European electricity grid.

Is Europe on Renewable Energy Target?

eu-targets[source, p30]
With seven more years to go to 2020, how far are individual EU countries away from implementing the ageed upon renewable energy targets for 2020? The usual suspects Sweden and Germany are doing fine. Denmark is not even listed, but is doing fine, no surprises here. Positive suprises from Spain, Italy and Portugal, disapointing results from the Netherlands and UK so far, but it needs to be mentioned that both countries recently announced ambitious plans to catch up on time [Netherlands, UK].

[ec.europa.eu] – Renewable energy Targets by 2020.
EU will reach a 20% share of energy from renewable sources by 2020 and a 10% share of renewable energy specifically in the transport sector… On 31 January 2011, the European Commission (EC) presented its Communication showing that the 2020 renewable energy policy goals are likely to be met.

In the European Union, Member States are subject to Directive 2009/28/EC on renewable energy, implemented by Member States by December 2010 which sets ambitious targets for all Member States, such that the EU will reach a 20% share of energy from renewable sources by 2020.

Electric Energy Consumption Country Ranking

electricity-consumption-country-ranking
Interesting details: most western European countries consume ca. 20 kwh per day (Germany, France, Spain, Netherlands, Russia). US citizens consume almost double that amount: 39 kWh. Canadians top the list with 52 kWh, Australia 34 kWh. Coming world power China is at 7 kWh.

BritNed

Wikipedia: BritNed is a high-voltage direct-current (HVDC) submarine power cable between the Isle of Grain in Kent, the United Kingdom; and Maasvlakte in Rotterdam, the Netherlands. The BritNed interconnection would serve as a vital link for the foreseeable European super grid project.

NorNed

Nordned_cable[source]
There can only be one energy strategy for Europe in a resource depleted future: the European supergrid, a pan-European infrastructure, consisting of renewable energy generation, mainly based on wind and solar and large scale hydro storage to filter out intermittent energy supply from said sources. NorNed was a major step towards that integrated renewable European energy future. After 2020 slowly declining fossil fuel supplies from Russia need to be gradually replaced by this renewable infrastructure, probably combined with severe energy saving measures as well as rationing.

Wikipedia: NorNed is a 580-kilometre (360 mi) long HVDC submarine power cable between Feda in Norway and the seaport of Eemshaven in the Netherlands, which interconnects both countries’ electricity grids. It is the longest submarine power cable in the world.[2] Budgeted at €550 million, and completed at a cost of €600m,[3] the NorNed cable is a bipolar HVDC link with a voltage of ±450 kV and a capacity of 700 MW. NorNed is a joint project of the Norwegian transmission system operator Statnett and its Dutch counterpart TenneT… After two months of operation, the cable generated revenues of approximately € 50 million, meaning that in two months’ time, 8% of the total costs of the cable have been recovered. In the business case drawn up for the NorNed cable, annual revenues were estimated at €64 million. NorNed has been included in European Market Coupling Company operations as of 12 January 2011.

[en.wikipedia.org]

Translated Dutch wikipedia: the cable is a big success; in 2008 (cable in use for merely eight months) 3000 GWh were imported by the Netherlands and 330 GWh were exported. The cable is used to import cheap clean hydro electricity during the day from Norway. During the night cheap Dutch electricity is exported to spare reserves in the Norwegian hydro bassins or even to pump up water into the bassins. In this way the lakes are used to store energy that can be easily be reovered for times of peak demand.
