Basic Design - Atomic Rockets

Everything about fundamental spacecraft design revolves around the Tsiolkovsky rocket equation.. Δ v = V e * ln[R]. The variables are the velocity change required by the mission (Δ v or delta-V), the propulsion system's exhaust velocity (V e), and the spacecraft's mass ratio (R).Remember the mass ratio is the spacecraft's wet mass (mass fully loaded with propellant) divided by the dry mass

Power-to-gas - Wikipedia

Storage function. Power-to-gas systems may be deployed as adjuncts to wind parks or solar-electric generation.The excess power or off-peak power generated by wind generators or solar arrays may then be used at a later time for load balancing in the energy grid.Before switching to natural gas, the German gas networks were operated using towngas, which for 5060 % consisted of hydrogen.
