Cheap energy storage speeds up
Costs of producing renewable energy keep coming down; and technologies for cheap energy storage keep evolving. Therefore, the eternal problems with solar and wind energy appear to be more and more outdated (‘what to do if the sun doesn’t shine and the wind doesn’t blow’). In the past, we already devoted our attention to this
Renewables versus nuclear – a choice already made
The most important low-carbon energy sources, renewables and nuclear, compete for investment funds. But if we are not mistaken, the dice have already been thrown in this contest of renewables versus nuclear. Renewables have won. Although it might still take a decade or more for parties involved to agree on that. In two articles, we
Energy policy: don’t just choose low-carbon – create a new energy system
A recent article in Nature Energy confirms what we might have surmised already: renewable sources are much better at creating a low-carbon energy future than nuclear power. They do need quite another electricity infrastructure. But grid companies quickly learn how to change their energy policy, and create a new system that fits well these new
Plastic recycling: urgent, but a major problem
Suddenly, articles on plastic recycling pop up everywhere. Spurred on the one hand by continued growth in plastics production; and on the other hand by the ever growing problem of plastic waste. Scientists foresee that in 2050, there will be more plastic waste than fish in the oceans – if present trends continue. Something needs
New technology for drinking-water production
Researchers at Monash University in Melbourne, Australia, have developed a new technology for drinking-water production. They use metal-organic frameworks (MOFs) that remove ions dissolved in salt or brackish water, producing potable water. The MOFs can be regenerated quickly, under the influence of sunlight. Therefore, this results in a scheme of producing drinking-water from salt water
Energy autarky more difficult than expected
The Dutch Wadden islands aimed to attain energy autarky in 2020. They fail to reach that target. For in order to do this, energy production and consumption don’t just need to match over a year; they also need to match continually, whereas both production and consumption vary considerably over time. That is difficult to achieve.
Battery technology in fast development
Much excitement in the universe of battery technology. Battery storage is rapidly growing world-wide, important for the energy transition. Batteries are improving and their costs are falling, all the time. And the million-mile battery might be coming soon. Meaning that the battery would far outlive the car and could have a second and third life.
Scale issues in the energy transition
The energy transition has progressed quite a bit. To the extent that we can predict the outcome: renewable energy sources will win. But the real problems are surfacing now. The old energy system and the new energy sources have a scale mismatch. That will prove to be the source of much misunderstanding, conflict, and finally
