Green hydrogen took center stage at a recent roundtable discussion on decarbonization, gathering leading energy experts to explore its role in transforming the economy. The event highlighted how green hydrogen could be scaled in Spain with its strong renewable energy base, and how this model might inspire progress in North America as well. The session examined pathways for integrating green hydrogen into industry, transport, and power systems, with a view toward broader adoption across sectors. The proceedings are expected to be published in Madrid and on the partner publication’s website, continuing the conversation about a clean energy future.
Hydrogen is the most abundant element in the universe. Under ordinary conditions it remains a gas and often exists bonded with oxygen or carbon. It is not a fuel that can be directly harvested from nature; it must be produced through chemical or energy-driven processes to obtain it in a pure form.
Hydrogen boasts high energy density, with one kilogram delivering more energy than many other fuels. Vehicles powered by hydrogen in internal combustion engines are more efficient than those running on gasoline, according to assessments by the National Hydrogen Center. Additionally, hydrogen can generate electricity through fuel cells, offering a potential solution to long-term energy storage challenges.
The environmental footprint of hydrogen depends on the energy source used to produce it. Green hydrogen is obtained through renewable energy, typically via electrolysis, and emits little to no greenhouse gases when produced and used. This makes it a cornerstone of low-emission transportation and industrial processes.
As a pioneer in renewable energy deployment, Spain is seen as a strategic hub for green hydrogen development thanks to its clean energy infrastructure. A dedicated expert panel explored the future of this energy carrier and its role in supporting economy-wide decarbonization. The discussion featured voices from the sector, including leaders from major energy players, academia, and research institutions. The moderator guided the conversation to ensure a practical, policy-oriented outlook.
Participants noted that a national plan is essential to scale green hydrogen across industries such as heavy industry, freight and rail transport, shipping, and eventually residential energy use. Specific needs vary by sector, but the consensus is clear: the future hinges on green hydrogen. The opportunity is there, and momentum should be seized to accelerate implementation.
“Green hydrogen serves as a pillar in the energy transition”, articulated a leading researcher. “The goal is to harness renewable energy to store and move power where it is needed. Hydrogen acts as an energy vector that unlocks new possibilities for decarbonization across the economy.” This stance reflects the strategic posture of energy companies seeking to position hydrogen at the center of transport and industrial strategies, with biofuels and renewable hydrogen playing complementary roles in reducing emissions.
The expert panel underscored the importance of actionable plans to deploy green hydrogen effectively. A robust national strategy is needed to support industrial processes, long-haul transport, rail networks, and maritime shipping, with eventual expansion into residential energy use. Sector-specific roadmaps are required to meet the distinct demands of each application, ensuring that progress is practical and measurable. The conversation closed with an optimistic note: the pathway to a green future is visible, and timely action can unlock substantial benefits for energy security and economic resilience. The audience left with a clear sense that collaboration among policymakers, industry, and researchers will be the deciding factor in realizing this potential.
