Smart inverters have opened up opportunities for people with smart inverters to be paid for providing stored energy on demand and other grid services.
The study considers options including an inverter loading ratio of up to 1.7 and DC-coupled batteries, and how increasing levels of PV on the grid influence the optimal PV system design.
More states require data-rich maps for solar developers, but face challenges in setting requirements to ensure the maps are accurate, useful, and timely.
Tripling the amount of solar to be added in the Carolinas compared to Duke Energy’s plans would yield cost savings, a Brattle Group study found.
As fossil generators are phased out, grid-forming inverters will need to be phased in so that the grid can be restarted after any blackout.
Several of the projects also aim for lower costs for PV module materials or PV racking, as well as for lower defect rates on module assembly lines.
The national laboratory developed the baseline products to develop and document transparent, normalized technology cost and performance assumptions.
The engine manufacturer is the latest to test technology that can combust hydrogen blended with natural gas. The goal of reaching 100% hydrogen for electricity production will require more work.
A meta-analysis of seven studies that model clean energy policy packages highlights the “profound benefits and feasibility” of achieving 80% clean electricity by 2030.
Even 100% renewables could be reached with existing technology, the study said. Stanford University’s Mark Jacobson commented that system costs would be even lower with additional measures.
