This page provides an English interface to the gxceed GX paper corpus. The corpus aggregates papers from 14 contributing scholarly metadata sources and uses AI-assisted classification to identify signals related to measurement, policy narratives, outcomes, implementation, industrial adoption, and verification.
The goal is not only to discover papers, but to observe how GX research is distributed across research substance, implementation narratives, external expectations, implementation substance, and judgment formation.
Summaries are AI-assisted. Always refer to the original paper for authoritative conclusions.

This study assesses underground hydrogen storage (UHS) in a tight sandstone basin for Thailand's Mae Moh coal plant transition using 50-year reservoir simulations. Hysteresis limits base-case recovery to 37%, but a dual-production well desi…
J.C. Castro-Domínguez, A. Avila-Nuñez, K.G. Cedano-Villavicencio +2
A conceptual piece positioning hydrogen as a building block for Mexico's future decarbonization. No abstract is available, but it appears to discuss the policy and industrial implications of hydrogen in the energy transition. Relevant as a …
Chuan Ding, Zejing Song, Nannan Qu +4
Two biogas-to-hydrogen routes—pre-reforming decarbonization (A) and direct reforming (B)—were modeled in Aspen Plus and compared via TEA and LCA. Process B yields 7.8% more H2 but uses 9.9% more electricity; baseline LCOH is slightly lower …
Lüddeke C.T.
This study compares working gas capacity, deliverability and production behavior of hydrogen versus natural gas in porous-reservoir subsurface storage. It assesses how hydrogen's lower energy density and distinct flow properties constrain s…
Oliveira A.M.
This paper discusses building a green hydrogen economy as a pathway toward a renewable-energy-based society. It appears to examine hydrogen production, transport and end-use system design and hydrogen's role in decarbonization. No abstract …
