Scotland towards 2045: The challenge of leading with green hydrogen and renewable energy

Scotland is working on building an energy system based on green hydrogen, with a target of 25 GW by 2045. Additionally, it is consolidating its leadership in wind energy and hydroelectric production, while addressing technical and economic challenges along the way.

Scotland has positioned itself as a global leader in sustainable energy transition, charting an ambitious path towards carbon neutrality. According to Ali Javed, a specialist in hydrogen and renewable energy, the nation aims to produce 25 GW of green hydrogen by 2045, a significant leap from the 5 GW projected for 2030. “Green hydrogen is a developing field with technologies still at the research stage, but it holds immense potential to transform the energy system,” Javed highlights in an interview with Strategic Energy Europe.

Green hydrogen, produced through electrolysis using renewable electricity, is viewed as a key solution for decarbonising sectors that are hard to electrify, such as heavy industry and transportation. However, its production remains costly and highly energy-intensive. “In Scotland, we rely on electrolysis, but this process demands large amounts of electricity. Countries like France, with cheaper nuclear energy, have a competitive cost advantage,” Javed explains.

Technical Challenges and Infrastructure Progress

Scotland has made significant strides in integrating hydrogen into its energy matrix by developing a network of 13 hydrogen hubs. These hubs will connect with onshore and offshore wind farms where hydrogen will be produced, stored, and distributed across Scotland and Europe. Javed notes, “Hydrogen is highly flammable, so modifications to the current natural gas network are being evaluated to adapt it for hydrogen transportation.”

Energy storage is also a priority in Scotland’s strategy. The country has secured €800 million in investment to construct storage facilities capable of holding 1.5 GW of energy, enough to power one million homes. “This is a major step forward, especially considering Glasgow, our largest city, has approximately that population,” Javed adds.

The Role of Renewable Energy in Scotland

In 2023, Scotland generated 87% of its electricity from low-carbon sources, with wind energy playing a dominant role. The country is home to the world’s first floating wind farm, demonstrating its ability to innovate and adapt to its geography. Additionally, the government plans to add 28 GW of offshore wind capacity in the coming years, cementing Scotland’s leadership in this technology. “Offshore wind is our priority, given our favourable geography,” Javed states.

Hydropower also plays a vital role, with Scotland producing 85% of the UK’s hydroelectric power through 58 dams that generate 1,800 MW. The goal is to increase this capacity to 5,000 MW by 2045. Meanwhile, solar energy faces limitations due to Scotland’s climate, though its potential is being explored in specific areas.

Public Policy: Driving Change

Scotland’s renewable energy success is largely attributed to clear and ambitious public policies. According to Javed, “Defined goals and subsidies for private companies are crucial to encouraging investment.” Measures include tax incentives and grants for innovative projects, which facilitate the development of technologies like green hydrogen.

However, bureaucracy and budget constraints remain significant challenges. “While Scotland’s regulatory framework is more accessible than in other European countries, financing large projects remains a hurdle. This is especially relevant considering the current global economic limitations,” Javed adds.

Social Impact and Future Perspectives

Despite technological advances, the energy transition presents significant social challenges. Javed explains that the shift to renewable sources like green hydrogen could impact employment. “A coal plant can employ a thousand people, whereas a wind farm or hydrogen plant might need only a handful of technicians for its operation,” he notes. This highlights the need to create new job opportunities in related sectors, such as research and development, to mitigate workforce impacts.

Looking ahead, Scotland remains an example of how countries can combine ambition, innovation, and public policy to move towards sustainability. However, achieving the 2045 targets will depend on overcoming technical and economic challenges along the way.
