Ramboll is opening up new business opportunities in the green energy transition. A global shift from fossil fuels to renewable energy is urgently needed to avoid the worst impacts of climate change and power a low-carbon economy. Here’s how Ramboll is driving the green transition with green hydrogen and Power-to-X. 

With more than three decades of experience in the renewable energy industry, Ramboll is at the forefront of designing and deploying technologies that drive the green energy transition. 

From offshore wind turbine foundations, to innovative district heating and cooling systems, and the world’s most efficient waste-to-energy facility – to name a few. 

As a leader in developing and delivering green technologies, we are helping companies and governments meet their climate targets. But there is a long way still to reach global net zero emissions by 2050 and avoid irreversible climate impacts. Today, 83% of global energy demand comes from fossil fuels which contribute about 75% of global carbon emissions. 

Demand for energy – especially electricity – is set to rise 50% worldwide towards 2050, driven by rising populations and economic growth, according to the International Energy Agency. A massive expansion of renewable energy, especially wind and solar power, is needed to meet this demand sustainably.


Green hydrogen and Power-to-X

Green hydrogen is produced by using renewable energy – for example, produced from offshore wind farms – to split water into hydrogen and oxygen in an electrolyser without producing greenhouse gas emissions. 

The green hydrogen can either be used directly or synthesised using chemical processes into other fuels such as methane, methanol and ammonia. The use of electricity from renewable energy sources to create green hydrogen or synthetic fuels is defined as Power-to-X. 

Green hydrogen and synthetic fuels could be used in sectors which are dependent on fossil fuels for energy and are currently hard to electrify. These include long-haul trucking, shipping, aviation, as well as industrial manufacturing, green heating, and agriculture.


Solutions for hard-to-decarbonise sectors

In some sectors, such as shipping and aviation, there are still too few viable alternatives to fossil fuels. Emerging technologies like green hydrogen and Power-to-X could hold the key to decarbonise these sectors, but they rely on still more power from renewable sources to reach the scale needed for significant reductions. 

At Ramboll, we are deepening our presence in these emerging technologies, with more than 60 Power-to-X projects and studies in our portfolio. 

Prominent examples include a masterplan for the world’s first artificial energy island; an offshore bunkering station for sustainable maritime fuels; and a safety and risk analysis for Europe’s largest Power-to-X facility for manufacturing green ammonia. 

As demand rises, these projects could pave the way for an accelerated and scaled-up deployment of green hydrogen and Power-to-X technologies. The EU Commission estimates green hydrogen to meet 24% of global energy demands by 2050. 

The sooner the technology reaches scale, the greater the impact in reducing global emissions.

Reorganising for the energy transition

To deepen our commitment to the energy transition, Ramboll in 2021 decided to create a 500-person strong Energy Transition division. It will cover services such as hydrogen, Power-to-X, gas storage, and transition of the oil and gas, and power generation sectors. 

We are also building a dedicated team for wind energy, encompassing site assessment, asset management, project development, and advisory.

Catalyst for climate action

Throughout 2021, we raised our voice on the climate agenda. Our aim was to convene key actors and ramp-up action on the green transition.
