Wastewater contains an elevated amount of chemical energy in the form of organic contaminants. In order to make use of this energy, researchers from around the world study ways to recover it in the form of hydrogen, a process which efficiently eliminates organic matter from wastewater.
Scientists from the National Physical Laboratory (NPL) have developed a novel reference electrode, and are working with hydrogen energy system manufacturer ITM Power to aid the development of hydrogen production technologies for renewable energy storage.
CorPower Ocean's new wave energy system generates five times more energy per ton of device, at one third of the cost when compared to competing state-of-the art technologies. Energy output is three to four times higher than traditional wave power systems.
Researchers have carried out a study research that enables to recover agricultural plastic waste and turns them into new materials with higher added value, low price and improved recyclability. This would reduce the environmental impact generated by agricultural waste.
If you thought it has been a while since you heard any more rumours about the long-awaited Apple TV, they are about to be replaced by even more exciting possibility that Apple may be about to build an electric car.
In this new system, the dissipated heat is used to produce superheated vapor of refrigerant which is effective to generate power through an organic Rankine cycle (ORC), and thus the solar-to-electricity efficiency of the system can be significantly improved.
Geoengineering, an emerging technology aimed at counteracting the effects of human-caused climate change, also has the potential to counteract political polarization over global warming, according to a new study.
Nearly all of the studies used to promote biofuels as climate-friendly alternatives to petroleum fuels are flawed and need to be redone, according to a researcher who reviewed more than 100 papers published over more than two decades.
Deep cuts in greenhouse gas emissions, while necessary, may not happen soon enough to stave off climate catastrophe. So, in addition, the world may need to resort to so-called geoengineering approaches that aim to deliberately control the planet's climate. That's according to a National Research Council committee that today released a pair of sweeping reports on climate intervention techniques.
The United States saw continued growth in renewable energy, natural gas and energy efficiency in 2014, according to the third annual Sustainable Energy in America Factbook. The Factbook shows that U.S. deployment of sustainable energy increased as prices continued to fall and that investment in U.S. clean energy grew at a higher rate.
