Importing lots of hydrogen over vast distances

Posted by Michael Liebreich in Energy storage No Comments »

Thread for those who think we’re going to be importing lots of hydrogen over vast distances.
Shipping liquid hydrogen is not going to be a thing. To understand why, you need to understand that hydrogen is basically liquid, -253C escapey, explodey expanded polystyrene. Read more…

SMART EVO FLEX TONE 5 (White) rolled

Posted by Marcel van der Steen in Uncategorized No Comments »

Here an LED line from . The measurements from OliNo show that the lamp emits a warm white (close to neutral white) light with a color temperature of 3205 K. The lamp consumes 9.0 W and has a luminous flux of 180 lm. This results in an efficacy of 20 lm/W. The lamps energy category label is G (2021).

This article shows the measurement results. Many parameters are also found in the eulumdat file.

See this overview for a comparison with other light bulbs.

This is how Big Oil will die

Posted by Seth Miller in Transport 1 Comment »

7 SistersIt’s 2025, and 800,000 tons of used high strength steel is coming up for auction.
The steel made up the Keystone XL pipeline, finally completed in 2019, two years after the project launched with great fanfare after approval by the Trump administration. The pipeline was built at a cost of about $7 billion, bringing oil from the Canadian tar sands to the US, with a pit stop in the town of Baker, Montana, to pick up US crude from the Bakken formation. At its peak, it carried over 500,000 barrels a day for processing at refineries in Texas and Louisiana.

The Compact Flicker Degree (CFD) parameter, a measure for the flickering of lamps

Posted by Marcel van der Steen in Explanation, Led lights No Comments »

CFD_article_teaserThe light coming from (LED) lights can flicker. This effect is measured by OliNo for years already. The parameters given say something about the intensity variations and the frequency, but do not give a verdict. However Peter Erwin, aka Der Lichtpeter, has developed a parameter, called the Compact Flicker Degree (CFD), that analyses the flickering of lamps over a wide spectrum of frequencies and results in a value evaluating the flickering. Also it gives a color result like a traffic light. This article explains the parameter.

How Three Brand-New Power Plants in the Netherlands Are at Risk Already of Becoming Stranded Assets

Posted by Jeroen van Agt in Unsustainable No Comments »

kolencentrale-engie-rotterdamCoal-fired power generation is vulnerable everywhere to increasingly ambitious initiatives to cut carbon emissions.

This is acutely evident today in the Netherlands, where a recent court ruling and a parliamentary motion supporting tougher actions to avert climate change represent a growing trend.

This report assesses the impact of national pressures and beyond on the value of three new coal-fired power plants put into service in 2015 by the German energy companies RWE and Uniper, and the French energy company Engie.

More broadly, we note the implications from these examples for the business case for new-build coal power in Europe and further afield.

CO2 as solution for heating, not as a problem

Posted by Tinus de Vreugd in Energy saving 1 Comment »

CO2 HeatpumpR744 is the refrigerant name of Carbon Dioxide (CO2), and is a natural gas which is all around us. In fact, we cannot live without Carbon Dioxide! As with anything, adding too much CO2 to our environment, while the demand of the natural use from nature, is rapidly decreasing by cutting down forests, also for the use of fire wood and fuel pellets, is becoming rapidly a problem.
