Abstract
Natural gas supplies nearly a quarter of the world’s energy and is growing faster than any other energy source. One pathway to reduce the CO2 emission intensity of natural gas without transitioning end-use infrastructure is to synthesize a natural gas substitute from CO2 and renewable energy via electrochemical CO2 reduction. To improve the economic viability of electrogas, this work examines the possibility of using electrolyzer products without downstream separation. We quantify the electrolyzer performance needed to replicate the key heating value, safety, and emissions characteristics of natural gas. We find that, except in the case of unrealistically high device performance, directly synthesized electrogas is unable to reproduce all necessary properties of natural gas. We discover, however, a range of safe and low-emitting electrogas compositions likely achievable with current technology that can be blended with natural gas to reduce its CO2 intensity while retaining sufficient heating value.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
