Fuel Cell CHP on a Site with No Heat Demand — Why a 36% Heat Utilization Line Decides It
A 42%-efficient fuel cell CHP unit must use about 36% of its recoverable heat before it saves primary energy. Why the decision flips on sites without heat demand, and how to size the unit.

Reformed vs Green Hydrogen — Supply Paths for Fuel Cell Power Plants Split on Continuity
Gray, blue and green hydrogen paths compared from the standpoint of continuous fuel cell operation, with the electrolyzer size and storage buffer needed to run 1 MW on solar-only green hydrogen.

PEM vs Alkaline vs SOEC Electrolysis — Which Handles Renewable Variability, and Why the Floor Decides
Electrolyzer choice under variable renewables turns on what happens when output hits the floor, not on stack ramp speed. Alkaline minimum load, SOEC hot standby and PEM cost compared by power source.

Ammonia Cracking vs Liquid Hydrogen — The Import Path Is Decided Backwards from the Final Consumer
The hydrogen import path turns on the purity the final equipment needs and the stockpile period, not shipping distance. Hydrogen density, cracking heat and a 30-day stockpile for 1 MW, calculated.

Hydrogen Fuel Cells vs. Lithium Batteries: Both Are EVs, So Why Do They Work Differently?
Battery electric vehicles (BEV) and fuel cell electric vehicles (FCEV) are both motor-driven, but they store and convert energy in fundamentally different ways.

Hydrogen Station 700 bar vs 350 bar — The Vehicle Tank’s Spare Volume Sets the Pressure
Doubling pressure gives about 1.7 times the density and only about 24% more theoretical compression work. The cost of 700 bar lies in pre-cooling and equipment rating.

SOFC Cascade Configuration: When Does It Beat a Single Stack?
Bumhan Fuel Cell’s 10kW cascade SOFC reached 60.8% electrical efficiency. The width of load swings decides between a cascade and a single stack.

SOFC Exports Expand: Where Grid-Interconnection Interfaces Diverge from Domestic PAFC
Based on Doosan Fuel Cell’s August 2026 SOFC export and domestic PAFC contracts, we compare how the two fuel cell technologies differ at the grid-interconnection interface and when each is favored.

SOFC On-Site Power for Data Centers: What Should the Startup Heat-Up Interlock Check First?
SOFC on-site generation for data centers is spreading, led by the U.S. Rather than treating it only as a way around grid delays, this post maps with an I/O map where the stack heat-up and purge interlocks collide with data center go-live schedules.

Doosan Fuel Cell Hit by CHPS Cuts: When Should Power Producers Favour the Switch to SOFC?
With CHPS auction volume cut by 30.2%, Doosan Fuel Cell’s PAFC business is at a crossroads and a shift to SOFC is under way. The conditions power producers need to weigh.
