Following global catastrophic infrastructure loss (GCIL), traditional electricity networks would be damaged and unavailable for energy supply, necessitating alternative solutions to sustain critical services. These alternative solutions would need to run without damaged infrastructure and would likely need to be located at the point of use, such as decentralized electricity generation from wood gas. This study explores the feasibility of using modified light duty vehicles to self-sustain electricity generation by producing wood chips for wood gasification. A 2004 Ford Falcon Fairmont was modified to power a woodchipper and an electrical generator. The vehicle successfully produced wood chips suitable for gasification with an energy return on investment (EROI) of 3.7 and sustained a stable output of 20 kW electrical power. Scalability analyses suggest such solutions could provide electricity to the critical water sanitation sector, equivalent to 4% of global electricity demand, if production of woodchippers was increased post-catastrophe. Future research could investigate the long-term durability of modified vehicles and alternative electricity generation, and quantify the scalability of wood gasification in GCIL scenarios. This work provides a foundation for developing resilient, decentralized energy systems to ensure the continuity of critical services during catastrophic events, leveraging existing vehicle infrastructure to enhance disaster preparedness.
