Twiggy Forrest's Billionaire Bubble On Hydrogen’s Risks - CleanTechnica

The article critiques Australian billionaire Andrew "Twiggy" Forrest's dismissal of the climate risks posed by hydrogen as an energy source, highlighting a broader trend of "hydrogen climate harm denial." During a discussion with UK climate policy expert Baroness Bryony Worthington, Forrest challenged the established science that hydrogen acts as an indirect greenhouse gas by inhibiting the breakdown of methane, a potent greenhouse gas. Forrest accused the Environmental Defense Fund of spreading misinformation, but the article clarifies that his claims contradict well-established atmospheric science. Scientific consensus shows that hydrogen competes with methane for hydroxyl radicals in the atmosphere, reducing methane’s breakdown and thereby prolonging its greenhouse effect. Studies since the 1990s have quantified hydrogen’s global warming potential (GWP), with recent research indicating a GWP over 20 years approximately 33-37 times that of carbon dioxide and over 100 years about 11-12 times. While exact values vary, the evidence consistently indicates hydrogen’s significant indirect warming impact, especially relevant
