How to harness the power of biosolids to make hydrogen
14 Sep 2020 at 6:59am
New technology uses biosolids to drive the chemical reactions needed to produce hydrogen from biogas. The circular economy approach means all the materials needed for hydrogen production could be sourced on-site at a wastewater treatment plant, without the need for expensive catalysts.
California offshore winds show promise as power source
8 Sep 2020 at 2:05pm
One of the challenges of moving toward fully renewable energy in California by 2045 is matching production to demand. Consumer demand peaks in the evening when solar energy is no longer available. Offshore wind energy has the potential to help meet this demand.

31 Aug 2020 at 9:42am
Researchers have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of the molecule is to capture solar energy efficiently and store it for later consumption.
Advanced biofuels show real promise for replacing some fossil fuels
24 Aug 2020 at 1:56pm
A new study predicted significant climate benefits stemming from the use of advanced biofuel technologies.
New insights for sun-gathering technologies
24 Aug 2020 at 11:44am
Researchers are taking a page from Nature's lesson book. Inspired by the way plants and other photosynthetic organisms collect and use the sun's radiant energy, they hope to develop technologies that harvest sunlight and store it as carbon-free or carbon-neutral fuels.
Wireless device makes clean fuel from sunlight, CO2 and water
24 Aug 2020 at 9:34am
Researchers have developed a standalone device that converts sunlight, carbon dioxide and water into a carbon-neutral fuel, without requiring any additional components or electricity.
Climate change impact on green energy production
18 Aug 2020 at 8:49am
As the climate of the planet is changing, many researchers are looking to more renewable energy sources. Researchers investigate whether the power generated by solar and wind farms would differ between current and future climates. The researchers focused on sites in Australia where variable renewable generators are located or are likely to be located in the future based on the Australian Energy Market Operator's system plan.
Converting solar energy to hydrogen fuel, with help from photosynthesis
17 Aug 2020 at 7:43am
Global economic growth comes with increasing demand for energy, but stepping up energy production can be challenging. Recently, scientists have achieved record efficiency for solar-to-fuel conversion, and now they want to incorporate the machinery of photosynthesis to push it further.
