Our green transformation


Ørsted was once one of the most coal-intensive energy companies in Europe. Today, we’re the world’s most sustainable energy company, and a global leader in the transition to green energy.

Our business transformation is a story of technological innovation, steep learning curves and difficult strategic choices that have led to long-term gains.

Our own green transformation took a decade. Our fundamental objective was to transform our business from one based on fossil fuels to one based on renewable energy, and to find a business model that is both environmentally and financially sustainable.

But our transformation is a small part of a much bigger transformation – one which is far from complete. If we as a global society, are going to reduce carbon emissions in line with the scientific advice, every country and every company needs to speed up action on climate change.

We hope that the story of our transformation will inspire other companies and countries to take the steps necessary to limit the temperature increases that are causing climate change, and  having detrimental effects on our global ecosystems. As our story shows, green transformation is possible. And it comes with huge opportunities for businesses, economies and local communities.

Let’s work together to create a world that runs entirely on green energy.


Orsted in the UK

In the UK our renewable energy projects are helping to support UK net-zero targets and benefit the communities in which we operate


Offshore Wind

The UK is home to the world’s largest offshore wind farms and here we have 12 operational offshore wind farms that we either own or partly own, one wind farm under construction and a further three in our development pipeline. We have 1,000 offshore wind turbines installed, which produce enough green energy to power over 4.4 million UK homes a year. This will increase to 5.6 million following the completion of Hornsea Two offshore wind farm.


Onshore wind

We’re continuing our green transformation journey by expanding into onshore wind energy. In April 2021, we announced the acquisition of Brookfield Renewable Ireland, which includes onshore wind farm projects in the UK and Ireland. Here in the UK, we have five onshore wind farms located in Scotland – one in construction, which will generate 62 MW of onshore wind energy when fully operational in 2022, and a further four projects in development.


Renewable hydrogen

Renewable hydrogen, also known as green hydrogen, will play a vital role in decarbonising industry and transport and enable the UK to reach its net zero ambitions.

We are one of the lead partners in a renewable hydrogen project called Gigastack. The project, based in the Humber, will use green electricity from an Ørsted wind farm to generate renewable hydrogen by electrolysis that will then be used by the Philips66 refinery


Energy storage

At Ørsted, we believe battery storage will play a crucial part in the future energy system as more of our energy comes from renewable sources.

We have taken our first steps into commercial battery storage by building and operating a 20MW project near Liverpool (called Carnegie Road), in addition to integrating a 2MW battery system into our Burbo Bank offshore wind farm.

Both projects, located in Merseyside, will help to keep the UK’s electricity grid balanced.



We have developed Renescience, an exciting first-of-a-kind technologies that increases recycling rates whilst simultaneously producing green energy.

Using enzymes, mechanical sorting, recycled water and anaerobic digestion, Renescience separates household waste into recyclables. Then it liquifies the organics from the waste and turns it into green energy.

The plant which treats up to 80,000 tonnes of waste per year, equivalent to waste from approximately 70,000 UK homes, is located in Northwich, Cheshire and was commissioned in October 2020.

Key Projects

Hornsea Two


Hornsea Two will be the world’s largest offshore wind farm and is already paving the way for future renewable energy projects which will have a significant impact on our mission to reach Net Zero.

The completed array will see 165 8MW Siemens turbines, with blades manufactured in Hull, installed offshore, each standing 200 meters above sea level, with a rotor diameter of 167 meters.  The offshore wind farm will have the capacity to provide electricity for well over 1.3 million homes in the UK. 





The Gigastack project, led by ITM Power, Ørsted, Phillips 66 Limited and Element Energy aims to aims to demonstrate the benefits of and potential for renewable hydrogen derived from offshore wind. The consortium will highlight the regulatory, commercial and technical challenges to be overcome, developing a blueprint for deploying scaleable electrolyser technology across the UK.


Renewable hydrogen is essential for the decarbonisation of those sectors where direct electrification is not viable. These include industrial clusters, transport modes such as heavy-goods vehicles, trains, buses, manual handling equipment and maritime applications as well as the gas grid. It will facilitate the Humber’s ambitious transition to net-zero greenhouse gas emissions by 2040 and by 2050 for the UK as a whole. This project will also support local content through the growth of UK manufacturing and supporting ambitions for Humber regeneration.
