CAES vs Redox Flow Batteries — Does Geology Provide the Storage Vessel, or Do You Buy It?
CAES and flow batteries both decouple power from energy, but their storage vessels differ. Energy-per-volume math and site-based selection criteria.
Energy comparison
Gas Turbine Peaker vs BESS — Peak Response Is Decided by the Charging Window
What separates a gas turbine peaker from BESS in peak response is how many days in a row peaks last. Charging-window math and criteria by peak type.
Converting a Coal Plant — Ammonia Co-firing, Gas Conversion or Retirement Plus ESS?
The key asset of a coal site is its grid connection, not the boiler. How the three conversion paths split on annual energy and inertia requirements.
Choosing Energy Sources by Comparing the Levelized Cost of Electricity (LCOE)
LCOE converts construction cost, operating cost and lifetime into a single metric for comparing different generation sources, but it leaves out the firming and grid costs that often decide the real answer.
Grid Inertia: Synchronous Condenser vs Grid-Forming BESS — The Cost Is in kVA, Not kWh
Inertial response needs only kWh-scale energy. The real cost drivers of synchronous condensers and grid-forming BESS, and how short-circuit needs decide.
Gas Turbine 1 GW + SMR 1.5 GW Sequential Deployment: The Conditions That Make It Work
The 2.5 GW gas-plus-SMR contract in Texas is not a choice of source but a sequential deployment that uses one connection point twice. Where it wins, and the boundary conditions that flip it.
Thermal Storage (Molten Salt) vs Battery ESS — Is the End Use Heat or Electricity?
What separates thermal storage from batteries is whether stored energy ends up as heat or electricity. Path efficiencies and molten salt sizing math.
ESS Batteries: When Does Switching to LFP Pay Off?
An electrical engineer’s reading of LG Energy Solution’s parallel NCM and LFP production at Lansing, laying out when switching ESS cell chemistry pays off and where that advantage flips.
Sodium-Ion Batteries for ESS: When Do They Beat LFP?
An electrical engineer’s reading of the CATL-SolarPro sodium-ion ESS contract: where cold climate and supply chain risk come first, and where energy density per footprint decides.
Solar-plus-ESS vs Green Hydrogen Co-firing: When Does the LCOE Crossover Come?
An LCOE comparison of solar-plus-ESS and green hydrogen co-firing. The application splits at a discharge duration of 4 hours.
