W|EPC: Hydrogen Roadmap – Future of Vehicle Transportation (Part 2) – Alternative Fuels – Efficiency & Safety:Trillions Or Billions In Renewable Energy – Vehicles Decide?A Carbon Neutral transportation network could require significant capital spending for a new renewable energy production and distribution systems. Some renewables (e.g. Solar and Wind energy) are variable daytime resources not available during peak energy demand. Hydrogen, Methanol, and Ammonia from electrolysis (eFuels) can be utilized to store this energy.A vehicle’s efficient use of that energy will determine the required energy production and supporting infrastructure costs.
