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.

The group called on regulators to reject the plan and asked why solar — at a near-term cost of $20 per MWh — was not selected over an existing fossil generator at $51.70 per MWh.

Widespread demand flexibility is seen as vital for California to reach its renewables goal. Real-time electricity pricing is one tool being considered.

New rules “effectively gut” the only federal policy requiring utilities to buy renewable energy, the lawsuit says, arguing that FERC’s rulemaking exceeded its authority and conflicts with Congress’s goals.

Industry groups focus on solar-plus-storage, or preserving the distributed solar industry, while a state agency aims to compensate rooftop solar at avoided costs and add a grid service charge.

A 90% clean grid with a transition to EVs would achieve lower electricity costs than one without, the study shows. Transmission investments would mainly be spur lines to new renewable generation.

Federal law prohibits solar fixed charges for rooftop solar, says a petition from four owners in Alabama.
