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.

Daimler to Build Giant Battery Factory in Germany

Kamenz, East-Germany

Europe is a front-runner in implementing renewable energy sources, but is lagging behind with producing essential electricity storage. This is about to change with Daimler’s planned new giant battery in Kamenz, Germany. Purpose: build batteries for 10 new Daimler EV-models, on the road by 2022. The plant will be carbon neutral, with a combined heat-and-power plant and solar power. The initiative is aimed at competing with Tesla.

NYT – Germany’s Offshore Wind Push

Published on 17 sep. 2014 – The small German island of Helgoland, a popular tourist destination, is undergoing dramatic change as the wind industry takes over.

New German Renewable Record

During past Sunday April 30, a breezy and sunny day, German coal-fired power stations produced an all-time capacity low; between 15-16 hour less than 8 GW (coal 1.8 GW, lignite 6.2 GW). Nuclear 5 GW. Solar and wind produced 55.2 GW at 12:00. Between 13:00-15:00 the renewable share was 85%.

This situation will be the new normal by 2030, 13 years from now. By 2022 nuclear will be completely phased out.

Germany 41% Electricity Renewable in March 2017

New monthly record in renewable electricity production in Germany: 41% or 19.5 TWh, where the nuclear power share fell to its lowest level since 1970. Additionally a new peak power record was broken on March 18 of 38.5 GW, topping the old one of 38 GW (Feb 22).

Cheap Electricity Storage for Households Underway

[source] “MyReserve”, 93% efficiency. 4,4 kWh; 6,6 kWh; 8,8 kWh; 11 kWh units

Solar installation company Solarwatt from Dresden/Germany has announced that it will offer batteries for substantially lower prices in the Summer 2017.
Price 4.4 kWh unit: 5.499 Euro

German price context:

1 kWh from the grid: 30 cent
1 kWh grid feed-in compensation: 12 cent
1 kWh cost from panel: 10 cent

Under these (very German) price conditions does it pay to install this Solarwatt battery.

This btw is still a far cry from the promised $100-200/kWh.

The World Doesn’t Have a Long-Term Energy Problem

[source]

Terra-Watts solar is coming, replacing Giga-Watts. This is the conclusion prominent scientists from the German Fraunhofer Institute (ISE) and US National Renewable Energy Laboratory (NREL) arrive at. They predict that by 2030, the global cumulative installed solar capacity will be 10-30 fold of what it is today. Solar panel producer “First Solar” predicts that as early as 2020, the price of solar panels will decrease to as little as 25 cents/Watt. That would mean that a standard 100 cm x 164 cm, 300 Watt panel costing € 300,- will cost € 75 in 2020. Solar panels as block-board.

Currently Abu Dhabi is able to produce solar electricity for a staggering low 2.4 cent/kWh.

There is no long-term global energy problem.

E.ON to Invest Millions in Energy Kites

The general idea is: at 450 m altitude the winds are much stronger and persistent than near the ground. So have an air-born kite with propellers generate energy for you and send it to earth through the cable. Typical power gain: 30 households. Prototype installation to be build in Ireland by German energy giant E.ON and Dutch startup Ampyx Power. A power plane lifts off on its own and once at operational altitude starts to generate energy. Claim: 20 times as much energy per installed device mass unit as conventional wind turbines.

Obviously most suitable for not too densely inhabited areas.

Daimler & Bosch Will Bring Autonomous Car Within 5 Years

Daimler & Bosch have no choice as all the other major players are doing it. In the long term it means the beginning of the end of private car ownership for many. The car fleet will become an extension of public transport. Substantially fewer cars will deliver the same transport effort. Autonomous driving cars will have a much higher occupancy rate, both in terms of hours per day on the road as well as the ability of transporting more than one person at the same time. Especially younger people can defer the moment of private car ownership until they are really settled, if they can be persuaded to own an expensive car at all, now that a much cheaper alternative will be available. Retired people won’t need to own an expensive car at all.

It is good for everybody except the car industry itself, that will sell decreasing numbers. It is good for the cities with fewer cars parked for 95% of the time and it is good for the environment as the same transport effort can be accomplished with fewer cars with corresponding less embodied energy. Commuting can be done by occupying cars with five or more rather than one passenger, by applying intelligent algorithms to match transport supply and demand, allowing for small detours and/or changing cars en route. Traffic jams will disappear as a consequence. The taxi driver will vanish once and for all.

The autonomous driving car, essentially a cheap taxi, could be a good compromise to continue to bring door-to-door transport for everyone, yet at the same time diminish the role the car is playing in day to day life.

Win-win situation.

Artificial Sun For Climate Friendly Fuel

The vision of cars driven by hydrogen has not materialized. Instead the battery and electricity seem to have won the competition. With airplanes it is different. Although electric planes could be reality in a decade or so, for longer distances this is not an option. Hydrogen could very well be.

The German Aerospace Centre DLR in Jülich has recently opened a research facility consisting of an artificial sun, with an intensity of 10,000 times the original. The idea is is to study how sun light can be used to generate “solar fuels”, like hydrogen.

Important Step Taken Towards Energy Hub North Sea

TenneT TSO B.V. (Netherlands), Energinet (Denmark) and TenneT TSO GmbH (Germany) today signed a trilateral agreement for the development of a large renewable European electricity system in the North Sea. This so-called ‘North Sea Wind Power Hub’ has the potential to supply 70 to 100 million Europeans with renewable energy by 2050.

This important step towards a broad consortium was taken in the presence of the European Commissioner for an Energy Union, Maroš Šefčovič. Mel Kroon, CEO of TenneT, and Torben Glar Nielsen, CTO of Energinet, signed an agreement aimed at investigating the feasibility of one or more ‘Power Link Islands’.

TenneT and Energinet, as well as any other parties that want to join, will spend a few years on investigating the details and potential of one or more Power Link Islands. If the TSOs decide to go ahead with the project, a Power Link Island could be developed by approximately 2035

Estimated size: 6.5 km2
Estimated cost: 1.25 billion euro

The island might feature power-to-gas as a storage technique to utilize high volumes of wind generation, said Rasmussen. The North Sea is home to a sophisticated network of gas pipelines, which could help bring wind-generated gas to countries around Europe.

“A part of this work will be to include power-to-gas technology and other storage technologies,” he said. “What, when [and] how much is what we will look into further. It is too early to go into details.”

[ifo.de] – Energiewende ins Nichts

Wir haben ein Klimaproblem: 85 Prozent des Endenergiebedarfs der OECD-Länder und auch der Bundesrepublik Deutschland werden aus fossilen Brennstoffen gewonnen. Davon müssen wir weg. Bislang schien die Atomkraft den Weg in eine klimaneutrale Energieversorgung zu ermöglichen. Mit der Energiewende und ihrem Ausstieg aus der Atomkraft und den fossilen Energien steht man nun mit ziemlich leeren Händen da. Die Vorstellung, die Energieversorgung Deutschlands mit Wind- und Sonnenstrom aus heimischen Quellen zu sichern, ist eine Illusion. Die unsichere Versorgungssituation ist Gift für die Investitionsplanung der deutschen Industriefirmen. Die deutsche Politik sollte umsteuern und ihren nationalen Alleingang aufgeben. Professor Hans-Werner Sinn erläutert in einem universitätsöffentlichen Vortrag in der Großen Aula der Ludwig-Maximilians-Universität die Konsequenzen der aktuellen Energiepolitik.

Blueprint for 100% Renewable Energy Base in Germany

d-erneuerbar[Source]Share renewable energy Germany timeline

The renowned German Fraunhofer research institute presented in 2012 a blueprint of how a 100% renewable energy base could be realized in Germany. From the summary (p31):

It is possible for Germany to have a 100% renewable energy base (electricity and space heating) with a cost comparable with today and equal electricity consumption. Assumed though is a reduction of 50% of energy required for space heating through insulation measures. Wind power opportunities need to be completely exhausted. Long term energy buffering can be done with methane gas produced from renewable electricity. Warm water production from solar collectors and industrial waste heat, combined with seasonal storage. Installed PV: 200 GW (1250 million m2), solar-thermal: 130 GW (190 million m2). 75% can be installed on existing building roof tops. Additional required surface area: 400 km2 (20 x 20 km) or 0.011% of Germany.
