Displacing grey hydrogen: 95% of today's hydrogen is made from fossil fuels

Moving to green energy: Low carbon hydrogen could supply up to 25% of the world's energy by 2050 with global usage of 450 million tonnes of green hydrogen1

Economies of scale: Low-carbonor clean hydrogen sector expected to generate $2.5 trillion in revenues by 2030, creating 30 million jobs2

Government support: US IRA - $370 billion in climate and clean energy investments. EU's €800m Green Deal. UK's Net Zero Hydrogen Fund

Investment needed: $5 trillion of investment is needed in the clean hydrogen supply chain to achieve net zero3
