Pledges provide hope that the climate crisis is being taken seriously, but whether words will translate into reality is yet to be seen.
Scaled and directly integrated PV-EC means big news for green hydrogen
Directly integrated photovoltaic–electrochemical devices could provide a viable path toward a green hydrogen economy.
Self-frosting glass could revolutionize sustainable buildings
Scientists have developed a polymer-coated glass that can change from transparent to opaque when exposed to sunlight and heat.
Electro swing direct air capture
An innovative advance dubbed “electro swing” may challenge the energy efficiency, capacity, and scalability of large-scale carbon capture.
The biodegradable battery
Researchers build a biodegradable mini-capacitor that consists of carbon, cellulose, glycerin, and table salt — and it works reliably.
Waste not want not with sustainable fertilizer
A new approach to the synthesis of sustainable ammonia and urea uses food waste and brown water as feedstocks.
Climate finance today has greater reach, but more private influence
As climate finance becomes increasingly private and debt-based, both risk slowing long-term decarbonization and a shift of power away from government toward market actors.
Inspired by the pufferfish, this hydrogel purifies water using nothing but sunlight
This method of purification under natural sunlight opens a new paradigm in clean water production using renewable solar energy.
DIY eco-friendly fertilizer
Miniature plasma reactors mimic how lightening makes renewable nitrogen fertilizer using just sunlight, water, and air.
Conducting the climate change orchestra
It is my hope that with the collaborative efforts of a unified world, the dark tones of the fossil fuel reliance and heavy pollution will fade to become a distant echo of our past.
