PEM vs Alkaline vs Solid Oxide Electrolyzers: The 2025 Hydrogen Technology Showdown

PEM vs Alkaline vs Solid Oxide Electrolyzers: The 2025 Hydrogen Technology Showdown

Alkaline electrolyzers use a liquid potassium hydroxide (KOH) electrolyte, operate at about 60–80 °C, and have decades of industrial use in chlor-alkali and fertilizer plants. PEM electrolyzers use a solid polymer membrane and typically operate at 50–80 °C, delivering very high-purity hydrogen (>99.999%), with iridium catalysts at the anode and platinum at the cathode. SOEC operate at 700–850 °C with a ceramic oxide-ion electrolyte, reduce steam to hydrogen, and can exceed 80% LHV electrical efficiency when heat is supplied, with Sunfire achieving about 84% LHV in a multi‑megawatt unit and NASA reporting a 4 MW SOEC system in 2023.

No Signal? No Problem – Starlink’s Direct-to-Cell Satellites Are Eliminating Dead Zones

Direct-to-Cell Revolution: What It Is and When It Will Work in Your Country

In August 2022, SpaceX and T-Mobile announced a partnership to add Direct-to-Cell texting via Starlink satellites, enabling roaming coverage for remote areas using SpaceX’s constellation. SpaceX launched the first Direct-to-Cell–equipped Starlink satellites in early 2024, and by mid-2025 there were about 400 such satellites in orbit. On January 8, 2024, SpaceX successfully sent a text message from a regular smartphone via a Starlink satellite through T-Mobile’s network. Starlink’s Direct-to-Cell service is expected to start with texting in 2024, add voice calls in 2025, and deliver modest data speeds later.
