World Hydrogen Week prompts a discussion on the potential of hydrogen in the energy mix. The article creatively uses a Sim City analogy to simplify the complexities of energy systems. The hypothetical city of Geraldineton in Western Australia explores different energy generation methods. It starts with a gas-fired power plant, then incorporates solar and wind farms to reduce costs and emissions. However, expanding renewables excessively leads to high electricity costs due to curtailed power. Introducing hydrogen production through electrolysis becomes a solution, utilizing excess electricity efficiently at $6.30 per kg. The article contrasts grid-connected and off-grid systems, highlighting the challenges and benefits of each approach. Overall, the sentiment towards hydrogen is positive, emphasizing its potential to address energy challenges in a future economy.
