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
Methane pyrolysis turns a grey resource into a green one
Bio is in. Chemistry is out. Green is in. Grey is out. And the Netherlands (my home country) should rid itself from its dependence on natural gas. These are popular opinions in ‘climate conscious’ circles. Yet there are ‘chemical’ processes that yield ‘green’ fuels. Methane pyrolysis is one of them. Almost all fuels emit CO2
Renewable energy imports
It its latest report, Boston-based Lux Research investigates a global and sustainable energy infrastructure. Can areas with high energy demand but not endowed with much domestic wind and solar energy become self-sufficient? Or will they need to import sustainably sourced energy carriers from elsewhere? And if so, in what form? Lux envisages a new market
Corona pandemic and energy transition
Will the corona pandemic speed up the energy transition? The question is much debated. Those who would like to accelerate the transition seem to have the upper hand, if we can judge by the headlines of the news. Fine particulate matter and corona pandemic We can add a new argument to this discussion. For there
