HMS.H2Real

H2Real – Realistic Hydrogen for Space Engineers 🚀

⚠️ Requires Heat Management System – H2Real is an official expansion module for it.

Hydrogen in vanilla Space Engineers is… let’s just say a bit too magical. H2Real fixes that with a grounded, science-based rework of how hydrogen tanks, generators, engines, and thrusters actually behave.

✅ Core Features

- Tank capacity equalization – gas amounts scale properly with tank size. - O2/H2 Generator realism – production rates and power consumption rebalanced based on real electrolysis math. - Hydrogen Engines – realistic fuel-to-power ratios, heat buildup, and O₂ consumption. - Hydrogen Thrusters – adjusted thrust and fuel use to match real exhaust physics. - O₂ requirement – both engines and thrusters now need oxygen to run. - Overheating consequences – push your tech too far and face the fallout: • Thrusters explode their emitter at 500 °C (20% grid damage, thruster disabled). • Engines fail at 300 °C (still nearly double real combustion engines).

Fully multiplayer tested and server compatible ✅

⚠️ Warning – This Mod Isn’t for Everyone

H2Real is designed for experienced players who want a true engineering challenge. If you install this mod, be prepared to: - ⚡ Suffer through enormous O2/H2 generator power demand. - 🚫 Forget about mobile refueling stations – no more carrying an entire hydrogen plant on a rover or small ship. - 🏭 Build stationary production facilities and stockpile fuel before attempting serious missions. - 🌍 Struggle against gravity – a single-stage launch won’t cut it anymore. Learn why most real rockets use staged launches… and start designing your own.

If you’re looking for casual plug-and-play hydrogen, this mod is not for you. If you want to feel the pain – and satisfaction – of real rocketry, welcome aboard. 🚀

Updates

v1.2.0: Controls refactor & consumption formula fix - Thruster and engine OnOff controls refactored: switched to a static terminal-level patch, no more per-instance subscription noise; falls back to vanilla cleanly if a block isn't tracked - H2 consumption formula corrected for both thrusters and engines: was hardcoded, now properly derived from fuel converter efficiency and actual thrust/output values - Benefits directly from the HMS 1.4.0 O2 Distribution rebuild: more stable O2 flow to everything that needs it

v1.1.0 - Mod now uses the HMS O2 Distribution System, which allows direct consumption, with no tanks required in the middle. - All recently added blocks are supported now.

v1.0.1 • Options for changing O2 consumption added.
