+name: alternative-fuels-engineer
+description: "Occupational skill for the role 'alternative fuels engineer' (also: alternative fuels expert, alternative non-fossil fuels engineer, alternative non-fossil fuels expert, hydrogen engineer, biodiesel engineer, fuel cell engineer). Use when the user asks for typical alternative fuels engineer work such as: Write technical reports or proposals related to engineering projects.; Read current literature, attend meetings or conferences, or talk with colleagues to stay abreast of new technology or competitive products.; Validate design of fuel cells, fuel cell components, or fuel cell systems."
+---
+
+# Alternative Fuels Engineer
+
+Alternative fuels engineers design and develop systems, components, motors, and equipment which replace the use of conventional fossil fuels as main power source for propulsion and power generation with the feature of using renewable energies and non-fossil fuels. They strive to optimise energy production from renewable sources and reduce production expenses and environmental strain. The alternative fuels employed mainly include Liquefied Natural Gas (LNG), Liquefied Petroleum Gas (LPG), biodiesel, bio-alcohol as well as electricity (i.e., batteries and fuel cells), hydrogen and fuels produced from biomass.
+
+## Core workflow
+
+1. Write technical reports or proposals related to engineering projects.
+2. Read current literature, attend meetings or conferences, or talk with colleagues to stay abreast of new technology or competitive products.
+3. Validate design of fuel cells, fuel cell components, or fuel cell systems.
+4. Simulate or model fuel cell, motor, or other system information, using simulation software programs.
+5. Recommend or implement changes to fuel cell system designs.
+6. Provide technical consultation or direction related to the development or production of fuel cell systems.
+7. Plan or conduct experiments to validate new materials, optimize startup protocols, reduce conditioning time, or examine contaminant tolerance.
+8. Integrate electric drive subsystems with other vehicle systems to optimize performance or mitigate faults.
+

+# External AI agent skills — alternative-fuels-engineer
+
+Proven, publicly available AI agent skills mapped to this occupation.
+Nothing is copied from the sources: every entry is a name, a one-line
+summary and a link to the upstream skill package. Each section names
+its source repository, commit, license and retrieval date.
+
+**Tiers:** `core` = the skill directly exercises a top market hard
+skill, tool or method (from gated job-ad evidence) or an essential
+ESCO competence of this occupation; `adjacent` =
+plausibly useful, secondary. Entries are capped at 12 per source
+and 80 in total per occupation (core first,
+strongest matches survive); everything beyond the caps is excluded
+and logged in the pipeline audit trail, not in this package.
+
+_Matched deterministically (ISCO group + title/competence keywords,

+
+## Description (ESCO)
+
+Alternative fuels engineers design and develop systems, components, motors, and equipment which replace the use of conventional fossil fuels as main power source for propulsion and power generation with the feature of using renewable energies and non-fossil fuels. They strive to optimise energy production from renewable sources and reduce production expenses and environmental strain. The alternative fuels employed mainly include Liquefied Natural Gas (LNG), Liquefied Petroleum Gas (LPG), biodiesel, bio-alcohol as well as electricity (i.e., batteries and fuel cells), hydrogen and fuels produced from biomass.
