General Fusion’s LM26 Crosses 1 keV Without Claiming Net Energy
LM26 reached a measured electron temperature above 1 keV during compression. The pre-peer-review result is a meaningful physics milestone, not net energy or electricity.
-
Geothermal Lithium’s Promise Depends on Mastering the Brine
Geothermal brine contains a potentially valuable lithium resource. Turning it into battery material requires selective extraction and a complete operating process.
-
Underground Hydrogen Storage Needs More Than an Old Gas Reservoir
Research supports reusing some gas-storage geology for hydrogen. Rock, microbes and withdrawal conditions still determine what each location can deliver.
-
Perovskite Solar Needs a Lead-Management Plan Beyond the Efficiency Record
Capturing lead after damage and recovering it at end of life solve different problems. Both belong in the design of a credible perovskite solar product.
-
Offshore Wind Farms Share an Atmosphere That Planning Must Account For
Satellite observations reveal long-range wake signatures behind offshore wind farms. Turning those signatures into reliable output forecasts requires more evidence.
-
Solar Power Can Go Unused for Two Very Different Reasons
AEMO separates generation curtailed by network constraints from output priced out of the market. That distinction changes how the problem should be understood.
-
AI’s Power Buildout Can Stall at the Transformer Factory
More generating capacity does not automatically deliver more usable electricity. Transformer supply ties the AI expansion to a slower industrial timetable.
-
Grid-Forming Inverters Must Prove Stability Beyond a Battery’s Megawatts
Grid-forming controls can help stabilise electricity networks. Field evidence, interoperability tests and protection-quality fault current are different parts of the proof.
-
Maryland’s Storage Awards Expose the Gap Between a Target and a Build
Maryland conditionally selected 440 MW in a storage round seeking 800 MW. The result shows how procurement, financing and construction remain separate steps.
-
GMG’s Fast-Charging Graphene Cells Improve, but Scale Remains the Test
GMG reports higher energy density and longer cycling in 1.5 Ah graphene cells. The small-cell tests leave pack performance and manufacturing to be demonstrated.
-
South Africa’s 4.6 GW Battery Plan Still Needs a Duration
South Africa has prioritised 4.6 GW of batteries and 5 GW of gas. Without storage duration, the battery number cannot show how much energy it can shift.

America’s Record Power Forecast Shows Why AI Cannot Explain Every Electricity Bill
The EIA forecasts record US electricity consumption through 2027. Its October outlook also separates demand growth, weather effects and the costs recovered in bills.
