A breakthrough in battery technology could make large-scale energy storage practical. Researchers at Harvard University say their organic flow-battery would be affordable and efficient. Professor Michael Aziz tells host Steve Curwood how the technology works and why it could significantly … Continue reading →
The German experience shows that there are some real challenges associated with renewables integration. But they're not technical — they are mostly related to rate structures, the high cost of legacy renewable energy subsidies and overlapping energy markets between countries. … Continue reading →
In the past few years, net-zero buildings—those that produce as much (or more) clean energy on site as they use annually—have been gaining momentum. Once considered a crazy idea, they’re now coming of age as a realistic goal for a … Continue reading →
1.3 billion people around the world – a quarter of humanity – have no access to electricity, and hundreds of millions more face regular blackouts. The effects of this energy poverty are enormous. Lacking power and light severely reduces a … Continue reading →
When SolarCity and Tesla last month announced they were teaming up to offer battery backup for residential solar PV systems, they generated much excitement … and a disproportionate amount of press. From Greentech Media to the New York Times, stories … Continue reading →
Researchers from North Carolina State University and the Chinese Academy of Sciences have found an easy way to modify the molecular structure of a polymer commonly used in solar cells. Their modification can increase solar cell efficiency by more than … Continue reading →
A team of Harvard scientists and engineers has demonstrated a new type of battery that could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and solar far more economical … Continue reading →
Two reports published by the US Energy Department’s National Renewable Energy Laboratory NREL show that soft costs — such as financing and other non-hardware costs — now make up the largest section of solar installation costs, coming in at 64% … Continue reading →
Top speed 50 mph, Range 125 miles, runs on compressed-air at a cost of 1 cent per mile and costs $10,000. In September 2013 it was announced that the car would be manufactured in Sardinia, Italy, for sale in summer … Continue reading →
SustainX's isothermal compressed air energy storage (ICAES™) technology enables a site-anywhere, zero-emissions storage solution. Through superior thermodynamics, SustainX technology frees compressed air storage from the risks of caverns and the emissions of natural gas. Isothermal compression allows air to reach … Continue reading →
