Green power on wheels: Hybrid engines fueled by sunlight and saltwater
This study assesses the feasibility of a hybrid vehicle powered by solar energy, hydrogen fuel cells, and an internal combustion engine, integrating a chlor-alkali electrolyzer with a gas-liquid absorption system. Tested in Ciudad Real under extreme summer conditions (up to 38.6 °C), the setup inclu...

| Sumario: | This study assesses the feasibility of a hybrid vehicle powered by solar energy, hydrogen fuel cells, and an internal combustion engine, integrating a chlor-alkali electrolyzer with a gas-liquid absorption system. Tested in Ciudad Real under extreme summer conditions (up to 38.6 °C), the setup included a hybrid electric (80 W)/combustion (2.5 cc) engine, 48 cm2 electrolyzer, 12 W fuel cell, four PV panels (10 W/240 cm2 × 2, 3.5 W/120 cm2 × 2), and a 1.0 L hydrogen tank. Charging used solar and grid electricity (5.83–72.23 Wh). Electrolyzer pressurization took 1–6 h, with chlorine/hydrogen evolution confirmed. Fast grid charging peaked at 132.7 mmol OH-. Five 30-min driving sessions showed energy use from 1.8 Wh (solar) to 13 Wh (combustion). Efficiency reached 6 % coulombic, 13 % energy. CO2 capture retained 35 mmol highlighting the hybrids potential for carbon reduction. |
