Electrolyzer Industry Statistics

Electrolyzer manufacturing is sprinting toward scale with a projected 25 GW of global capacity by 2027 and a 2025 push that includes 1 GW per year PEM stack output targets in Sheffield and Silyzer 300 production ramp plans. See how the economics are being reshaped by falling capex to about USD 650 per kW for 1 MW PEM systems in 2023 and growing stack efficiency, while a crowded pipeline of 400 GW announced projects still leaves only a small share ready for final investment.

Global electrolyzer manufacturing capacity is projected to jump from 3 GW annually in 2022 to 25 GW by 2027, even as individual manufacturers begin turning factory output into scaled megawatt lines. From ITM Power’s 20 MW/year PEM stacks in Sheffield to Gigafactory alkaline runs targeting 3 GW in Tennessee, the capacity buildout is accelerating faster than many supply chains can currently absorb. The result is a dataset packed with sharp contrasts between nameplate size, stack efficiency, and the cost and timing pressures that decide which projects actually make it to FID.
