WHAT IS HYDROGEN?
Hydrogen, the fundamental and most abundant element in the cosmos, stands as a quintessential force underpinning life itself, intricately woven into the fabric of existence. Manifesting as diatomic molecules in the form of H2, this colourless, odourless, and tasteless gas boasts attributes of non-toxicity alongside an inherent flammability and reactivity. On our planet, the unadulterated essence of hydrogen is a rarity, primarily intertwining with oxygen to birth the elixir of life, water

WHERE IS HYDROGEN USED TODAY?
In the European industrial landscape, hydrogen, measured in tons, assumes a pivotal role, predominantly in the chemical and refining sectors. Serving as the foundational element for ammonia synthesis, a precursor to fertilizer production, hydrogen's multifaceted utility is paramount. Beyond terrestrial applications, the National Aeronautics and Space Administration (NASA) elevated hydrogen to the cosmic realm, harnessing its propulsive power as rocket fuel in the spatial odyssey of the 1960s. However, despite its cosmic potential, hydrogen's ascension as a predominant fuel source on Earth remained constrained, tethered to the challenges of energy production and sourcing.
WHAT IS THE DIFFERENCE BETWEEN GREY, BLUE, AND GREEN HYDROGEN?
In the chromatic tapestry of hydrogen production, shades of grey, blue, and green have emerged, signifying distinct methodologies. Grey hydrogen emerges through steam reforming, a process entailing natural gas consumption, accompanied by the consequential generation of CO2. A nuanced transformation yields blue hydrogen, retaining the essence of steam reforming while integrating carbon capture techniques. In stark contrast, green hydrogen embodies the pinnacle of environmental harmony, birthing through the electrolysis of water. Propelled by renewable energy, this process is devoid of fossil fuel dependency and CO2 emissions, heralding a revolutionary chapter in sustainable production.
WHY IS GREEN HYDROGEN A MAJOR PILLAR FOR A NET ZERO ECONOMY?
In the symphony of sustainable energy, green hydrogen emerges as a resounding crescendo, echoing its indispensability in forging a net-zero economy. Acknowledging the energy losses inherent in its production, proponents advocate for its unique ability to transcend weather constraints and temporal fluctuations. Far surpassing the limitations of batteries, hydrogen, with its superior energy density, stands as a beacon of hope for long-term storage and efficient transcontinental transportation. The trinity of industry, transportation, and chemical feedstock beckons, with hydrogen poised to revolutionize heat, steel production, shipping, road transport, aviation, methanol, and ammonia production.
WHEN WILL THE SCALE-UP TAKE OFF?
The present moment serves as the launchpad for hydrogen's ascendancy to unprecedented heights. In an era where climate change commands the forefront of global discourse, hydrogen basks in newfound attention and substantial investments. Ninety nations stand committed to net-zero targets, propelling governments worldwide to earmark approximately €70 billion in public funds. Amid this surge, Europe emerges as the epicentre of hydrogen innovation, with the European Union boldly targeting a minimum 55% reduction in greenhouse gas emissions by 2030 and a definitive march towards net zero emissions by 2050. At the forefront, Germany assumes a leadership role, positioning itself to achieve net zero emissions as early as 2045. The symphonic crescendo of hydrogen's disruptive relevance harmonizes with the urgency of our times, ushering in an era where ambition converges with environmental stewardship.
