Energy Systems

Fast-tracking the energy transition

In 2021, DNV combined its Oil & Gas and Power & Renewables (Energy) businesses into one new business area called Energy Systems.

This move means we can better reflect the emerging energy future, which will see renewables take a greater share of the energy mix and decarbonization become a major focus. By bringing together our expertise from across the energy sector, we can better help our customers to scale green energy technology in a safe and sustainable way from production to energy use. We can also offer a broader, integrated set of global services for companies across various phases of their decarbonization pathway to reduce the impact of greenhouse gas emissions in the energy sector. This was reflected in project wins and customer success stories in 2021.

Developing Taiwan Power Company’s largest offshore wind farm

Taipower Offshore Wind Project Phase II (Changhua Phase II) is the largest offshore wind farm being developed solely by Taiwan Power Company. DNV signed its largest-ever offshore engineering agreement to support the project across its lifecycle right through to commissioning. DNV’s international and local experts are undertaking design reviews, fabrication assurance, and construction assurance. 

The project demonstrates the benefits of having an assurance partner that can support both offshore project engineering activities and marine coordination work. Taiwan aims to generate 20% of its electricity from renewables by 2025. By then, 5.7 GW of installed capacity is scheduled to be available from offshore wind farms, including Changhua Phase II.

Making hydrogen adoption a reality

DNV was chosen to lead a project to identify and analyse the main environmental, safety, and operational risks of the world’s first offshore floating green hydrogen production facility. The test site, located off the coast of France, is managed by Lhyfe, a producer and supplier of green and renewable hydrogen for transport and industry, and Centrale Nantes, School of Engineering and Research Centre. 

The project’s ambitious goal is to make offshore renewable hydrogen a reality by demonstrating the reliability of an offshore electrolyser. DNV’s experts hosted workshops and technical sessions to identify and analyse safety risks. 

The project represents a watershed moment for the adoption of hydrogen, a unique energy carrier with no carbon emissions that can be used for long-term storage and heating applications. Hydrogen is set to become increasingly economically viable due to the growing penetration of wind and solar power.

DNV fully accredited to offer type certification in China and Korea

In 2021, DNV became fully accredited by CNAS (China National Accreditation Service). This allows DNV to offer the type certification of wind turbines and component certification of gearboxes, rotor blades, and generators for products destined for Chinese wind power projects. 

At the beginning of 2022, DNV was also accredited to offer wind turbine certification in Korea.

Expanding DNV’s service offering and market reach

In 2021, DNV acquired the consulting arm of Antuko, a leading energy price forecaster specializing in quantitative analysis, risk assessment, market intelligence, transaction advisory, and market representation services. 

The integration of Antuko´s capabilities into DNV’s portfolio will offer customers, investors, financial institutions, owners, and operators a one-stop-shop covering both the technical dimension and commercial strategy of a project. 

To support the growing need to transform energy markets across all sectors and decarbonize the energy supply, DNV acquired US-based engineering consultancy Energy and Resource Solutions, Inc. (ERS). ERS works with utilities, governments, and large commercial and industrial end users to solve complex energy and resource problems. 

The domain expertise and digital-first approach demonstrated by ERS, combined with our shared commitment to sustainability, managing energy use and mitigating environmental impacts, will help industrial energy users across the world navigate the transition to a low carbon energy system.

Managing over 300 solar plants with an installed capacity of more than 850 MW

EF Solare Italia, the leading photovoltaic (PV) operator in Italy, signed an agreement to import its entire portfolio into DNV’s GreenPowerMonitor (GPM) Plus and GPM Horizon data monitoring platforms. GPM Horizon is a web-based real-time monitoring and management platform providing customers with tools to manage every level of their plant portfolio, plant supervision and operation, maintenance management, financial and asset management, automated reporting, forecasting, and much more. 

Italy plans to cut its carbon emissions by around 60% by 2030. The partnership between EF Solare and DNV will support the country in achieving this aim and highlights the commitment of both companies to play an active role in global decarbonization by using digital solutions. As of September 2021, DNV’s GreenPowerMonitor global portfolio surpassed 46 GW, split between solar, wind and storage energy.

Proving the safety case for hydrogen

Hydrogen will play a central role in our future energy mix. Assuring safety is a critical first building block in developing the use of hydrogen to decarbonize the energy supply to homes in countries such as the UK, where there is high dependence on piping natural gas for heating and cooking. To do this, DNV has specially designed and built HyStreet, a row of three ordinary-looking houses, at our testing and research facility in Cumbria, UK. 

In 2021, the team continued to conduct safety testing for the UK Government’s Hy4Heat programme, which aims to establish whether it is technically possible, safe, and convenient to replace natural gas with hydrogen in residential and commercial buildings and gas appliances.

Reducing earthquake challenges facing wind power plants

As wind power grows in markets such as Asia Pacific and the US, there is an increasing need to ensure the design of wind turbines and other wind power plant assets, such as the offshore substation, can meet the challenging conditions seen in those regions. In response to this, DNV has published the world’s first recommended practice (RP) to minimize cost, warranty, and liability risks, and optimize wind power plant design for seismic conditions. 

This recommended practice was the result of a truly global collaborative effort, which saw more than 20 wind industry leaders, including original equipment manufacturers (OEMs), project developers, designers, and experts from Asia Pacific, Europe, and North America, come together to align wind turbine design methodologies for extreme environmental conditions.
