Cumulative Dutch Renewable Electricity Production 2021

So far, 18 TWh electricity production from solar and wind, 20% more than last year. More solar, more offshore wind, but less onshore wind. 75% solar from roofs.

Ørsted €403m Cable Setback

[source] (picture not directly related to Orsted problems)

Offshore wind champ Ørsted reported major cables issues with several of its commissioned wind parks, that in the worst case scenario could amount to €403 million damages. Problems were noticed first at the UK Race Bank wind farm, but after inspections, up to ten other wind farms could be implied. Cables are being damaged by rocks on the sea bed floor.

Dutch Gov Wind Power Install Forecasting is Accurate


This blog started in 2012. While browsing through old posts, I noticed this one:

[deepresource] – Netherlands To Install 6 GW Wind Capacity By 2020

In 2012, the Dutch government announced its intention to have 6 GW wind power installed by 2020. The graph indicates that by 31-12-2020, the total installed capacity was offshore 2.4 GW and onshore 4.3 GW or 6.7 GW in total.

Not bad!

Donald Sadoway on Molten Metal Batteries

Specs Ambri liquid metal batteries:

Capacity: 400-1000 kWh, up to 250 kW
DC Efficiency: exceeds 80% under wide range of use cases
Response time: <500 milliseconds
Voltage: 500 —1500 V
Footprint: 10-foot shipping container

[] – Ambri’s liquid metal battery to be used at desert data centre in Nevada

Ambri has designed a battery that uses a liquid calcium alloy anode, molten salt electrolyte and a cathode made of solid particles of antimony. The company claims this enables a low number of steps in the cell assembly process while the materials are low-cost. Ambri also integrates the batteries into a containerised energy storage system solution.

Website comment: Bloomberg predicts $58,-/kWh for 2030. But, to its credit, this technology doesn’t use potentially scarce lithium. Interesting development.

Bloomberg – Europe Dominates the Renewable Energy Battle

Bloomberg is one of the very few authoritative voices in the North-American energy landscape that are sympathetic towards the renewable energy transition, because they think it can be done (and the US could miss the boat?). Yesterday they admitted that Europe is dominating the transition scene: and that especially their oil companies with deep pockets are committed to make it work, even if the largest share of their turnover is still based on fossil fuel:

European oil companies, including Total, Galp, Equinor, BP and Royal Dutch Shell lead a group of the 39 most publicly-traded oil and gas companies in preparedness for a low-carbon world, according to Bloomberg’s Climate Transition Scores. These companies have ranked highly due to ambitious climate targets and deep transition-related investments in an industry heavily exposed to transition risks in the face of widespread climate action. For example, these five oil majors own some 11GW, or 78%, of the renewable energy assets held by the 39 scored companies.

Energy Saving With Mist Showers

[] – Mist Showers: Sustainable Decadence?

Personal note and a little off-topic, but not completely. Ever thought of cold showers? It is not as bad as it sounds and you’ll get used to it. It took the author one month to increase endurance from 5 seconds to 5 minutes. Apart from zero thermal energy use, the habit comes with health benefits, like a stronger immune system, which could prove useful in these Corona times. And you get an energy boost, much stronger than coffee can achieve.

This pragmatic randomized controlled trial is the first study showing that a routine cold shower has a beneficial effect on health.

Global Pumped Hydro Atlas

Scientists have identified 530,000 sites worldwide suitable for pumped-hydro energy storage, capable of storing more than enough energy to power the entire planet…

None of the potential sites are located inside national parks or urban areas, and each one has the potential capacity to hold 2-150 GWh of energy…

The scientists say sites like the ones they’ve identified can operate at maximum power for between 5 and 25 hours…

“Pumped hydro accounts for 97 percent of energy storage worldwide, has a typical lifetime of 50 years and is the lowest cost large-scale energy-storage technology available.”

Tesla Solar Roof Tiles


Let’s be honest, even as supporters of the energy transition we have to admit that solar panels mounted to a roof do not exactly increase the aesthetics of the entire building. It’s much better to have the solar and roof function merged into one. That’s where Tesla solar roof tiles come in. Downside of the good looks, expect a price tag ca. twice as high for solar panels produced in China with the same electricity production. Tesla produces its tiles in New York.

Gordian Raacke – It Can Be Done 100% Renewable Energy

This talk is a wonderful global perspective on climate change and the effective actions we can take as individuals to collectively save the planet. Gordian Raacke is executive director of Renewable Energy Long Island, a not-for-profit organization working to accelerate the transition to 100% renewable energy systems. With a degree in civil engineer and 25-year track record on regional energy issues, Mr. Raacke will portray why and how we must and will transition to a 100% renewable energy supply glocally.

Gordian was a founding member of the Long Island Offshore Wind Initiative established in 2002, helped build the solar market on Long Island, and was trained by Vice President Al Gore as a Climate Reality Leader. In 2011, he led an initiative to study a one-hundred percent renewable electricity future for the region. He chaired the Energy Sustainability Committee of the Town of East Hampton and serves on the Town of Southampton Sustainability Committee, helping to formulate and implement community-wide 100% renewable energy goals. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at

Energie-eiland in de Westerschelde


The vision for the future: a series of energy islands for the coast of the Dutch province of Zeeland. Not pumped-hydro, but chemical salt-water storage, using osmosis, membranes and under water large plastic bags of 4000 m3 each, to store and retrieve renewable electricity. Zeeland needs 3 of these 5 km diameter islands to satisfy its own needs. Total storage capacity 900 GWh, sufficient to bridge 2 weeks. The islands are 100 times smaller than an energy storage-equivalent pumped-hydro storage would be, operating at 10 m height difference.
