How greener grids can stay lit
24 May 2018 at 11:15am
Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.

Symmetry is essential for power network synchronization
8 May 2018 at 6:49am
Scientists have clarified the fundamental principles for achieving the synchronization of power generator groups in power networks, which is essential for the stable supply of electric power. Based on this principle, the team developed a method for constructing an aggregated model of a power network that can efficiently analyze and control the behavior of generator groups (including rotor phase angles and connection point voltages) with complex connection to a power grid.
Novel approach for photosynthetic production of carbon neutral biofuel from g...
3 May 2018 at 11:27am
Reducing carbon emissions in order to prevent climate change requires developing new technologies for sustainable and renewable biofuel production. Molecular hydrogen is regarded as one of the most promising energy carriers due to its high energy density and clean, carbon-free use. A research group has discovered an efficient way for transforming solar energy into the chemical energy of biohydrogen through the photosynthesis of green algae that function as cell factories.
Engineers upgrade ancient, sun-powered tech to purify water with near-perfect...
3 May 2018 at 11:26am
The idea of using energy from the sun to evaporate and purify water is ancient. The Greek philosopher Aristotle reportedly described such a process more than 2,000 years ago. Now, researchers are bringing this technology into the modern age, using it to sanitize water at what they report to be record-breaking rates.
Harvesting clean hydrogen fuel through artificial photosynthesis
3 May 2018 at 11:26am
A new, stable artificial photosynthesis device doubles the efficiency of harnessing sunlight to break apart both fresh and salt water, generating hydrogen that can then be used in fuel cells.
