Hydrogen is often celebrated as the fuel of the future, heralded as a perfect solution that emits no carbon dioxide (CO₂) when burned or utilized in fuel cells. Yet, while technically correct — hydrogen itself emits no carbon dioxide upon combustion — the framing of hydrogen as a fully ‘clean’ … [continued]

A commonly cited argument is that surplus electricity from renewable sources, particularly solar and wind, makes hydrogen production both economical and practical. The rationale seems simple: when the sun shines brightly or winds blow strongly, there’s an abundance of electricity, potentially making hydrogen cheap. But this claim oversimplifies the economic … [continued]

Hydrogen is often promoted as a clean and efficient energy carrier, but its real-world efficiency is frequently overstated. Proponents of hydrogen fuel cells highlight their conversion efficiencies of 50–60%, comparing them favorably to internal combustion engines (ICEs). However, this selective framing ignores the full energy pathway, from hydrogen production to … [continued]

The latest hydrogen bus setback in Germany is no surprise. Essen and Mülheim are now stuck with 19 hydrogen buses that need to travel up to 89 km round trip just to refuel after the state of North Rhine–Westphalia withdrew its subsidy for further fleet conversion. The financial burden has … [continued]

Chris Wright, the newly appointed U.S. Secretary of Energy, has wasted no time in making his stance on energy policy clear. In his first major international speech at the Alliance for Responsible Citizenship (ARC) Conference in London, he framed net-zero as an economic disaster and defended fossil fuel expansion.
