The BrightVolt Take: China’s Coal Is Contracted to Run
China curtailed an estimated 360 TWh of wind and solar in H1 2026 – more than its entire demand growth – while adding 30 GW of coal. The waste is a policy choice, not a grid limit.
LMFP Batteries: What Manganese Adds to LFP
Lithium manganese iron phosphate is LFP with manganese added: about 3.7 volts instead of 3.2, and 15-20% more energy, at a small cost in conductivity and cycle life. Here is the trade.
Red States Are Building 71% of New US Solar
States that voted for Trump built 71% of new US solar in the first half of 2026 — led by Texas at 3.44 GW — even as Washington dismantles the credits that helped start the boom.
Capacity Factor: Why 1 GW of Solar Isn’t 1 GW of Gas
Capacity factor is the share of its nameplate a plant actually delivers – why nuclear makes 18% of US power from 7.7% of capacity, and why 1 GW of solar and 1 GW of gas are nothing alike.
Cost of Capital: Why It Sets the Price of Clean Power
A wind farm burns no fuel, so most of what it costs is the money that built it. That is why financing – 20 to 50% of solar’s lifetime cost – sets the price of clean power.
The BrightVolt Take: CATL’s Customers Are Going In-House
Li Auto just paid $390m for a board seat at a rival battery maker so it can design its own cells. It is the third premium Chinese carmaker to walk away from CATL – even as CATL’s profit jumped 42%.
The BrightVolt Take: China Taxed Lithium and Spared Sodium
On 1 September China began taxing lithium batteries at 2%, rising to 4% in 2027, while zero-rating sodium-ion and solid-state through 2028. That is not a subsidy cut – it is Beijing picking a chemistry.
Contracts for Difference: The Two-Way Clean-Power Deal
A contract for difference fixes the price a wind or solar farm is paid, and pays money back to consumers when the market runs above it. In Britain’s 2021-23 price spike, that returned around £660m.
ProLogium Starts Solid-State Battery Mass Production
ProLogium says it has begun mass-producing an all-solid-state battery cell at 381 Wh/kg, denser than any lithium-ion cell in a car today. But the cells are going into drones, not cars.
