Fuelsare

Fuelsare is a term used in speculative energy discussions to denote a proposed class of energy carriers intended to serve as versatile, low-emission substitutes for fossil fuels. It is not a standard term in current peer-reviewed literature and has no single agreed-upon definition. In a hypothetical framework, fuelsare would encompass fuels or energy carriers designed to be produced from renewable electricity and various feedstocks, with broad compatibility across transportation, heating, and power generation.

Conceptually, fuelsare aims for cross-cutting applicability and high energy density while achieving measurable lifecycle emissions reductions. The idea emphasizes minimal changes to existing infrastructure, enabling engines, pipelines, and storage systems to handle a range of fuels within a common framework. Formulations could include synthetic hydrocarbons, alcohols, hydrogen carriers, or other chemical energy carriers produced by power-to-X pathways, depending on project goals and resource availability.

Production routes envisioned for fuelsare typically involve electrochemical synthesis using renewable electricity, carbon sources such as CO2, and hydrogen, or biomass upgrading and direct air capture combined with synthesis. The specific chemistry and process efficiencies would vary by implementation, with attention to overall system energy balance and emissions.

Applications span transportation, residential and industrial heating, and power generation, with the goal of providing a single family of fuels that can be substituted for conventional fuels without extensive retrofits. Environmental and economic outcomes hinge on electricity carbon intensity, production efficiency, and scale, making fuelsare a topic of debate and ongoing research rather than an established, regulated category.
