Rolls-Royce and Sustainable Development Capital to offer ‘Energy-as-a-Service’

Rolls-Royce has agreed to a cooperation with the global investment firm Sustainable Development Capital LLP (SDCL) to jointly offer ‘Energy-as-a-Service’ solutions that can help accelerate the take-up of more sustainable power in applications such as mines.

The agreement, signed at the World Climate Conference (COP26) in Glasgow on November 11, allows Rolls-Royce to provide customers with electricity and/or heat, generated by a sustainable and efficient energy system, as a subscription service, removing the need for customers to secure up-front infrastructure finance or operate the system themselves.

“The provision of ‘Energy-as-a-Service’ where a customer pays for heat and power through a subscription model, represents a very attractive way to improve access to sustainable power,” Rolls-Royce said. “Rolls-Royce will work with SDCL and other partners to design, finance, build, commission and operate new projects.”

SDCL has more than a decade of experience of developing and financing clean and decentralised energy infrastructure projects in the UK, continental Europe, North America and Asia. Rolls-Royce, through its Power Systems business unit, has a portfolio of microgrid systems that bring together renewable energy sources such as solar and wind power with mtu-branded battery storage and gensets to ensure reliable power generation. It is currently developing fuel cell systems and making its existing mtu engines compatible with sustainable fuels, paving the way for net zero microgrid solutions within the next two years.

Examples of ‘Energy-as-a-Service’ projects can range from providing sustainable and reliable power for communities in remote areas that are not connected to a public power grid; to industrial parks that want to be supplied with green power as well as emergency back-up and mines that want to replace old, inefficient, equipment to meet new regulatory requirements and make use of as much renewable energy as possible.

Andreas Görtz, Vice President Power Generation at Rolls-Royce Power Systems, said: “Energy-as-a-Service is particularly interesting for companies that need to adapt their energy supply to new circumstances – be it an expansion for which more power is needed or an adaptation to new regulatory requirements, such as emissions guidelines. Because this often involves investing in equipment, such as a microgrid, that requires expertise to operate, it’s a challenge for customers to do this on their own. By offering Energy-as-a-Service, we can help them overcome that challenge.”

The portfolio of energy systems that can be made available through ‘Energy-as-a-Service’ to provide electricity and/or heat, ranges from smaller plants using combined heat and power units to battery containers and complex microgrid solutions, Rolls-Royce said. The existing mtu product range will be expanded in the coming years to include new technologies such as hydrogen-powered engines, fuel cell systems and combustion engines that can be operated with sustainable fuels such as e-diesel and hydrotreated vegetable oils.

Perry Kuiper, President Sustainable Power Solutions at Rolls-Royce Power Systems, explained: “Industrial companies and other businesses that rely on environmentally and climate-friendly energy can avoid ever-increasing energy and grid connection costs as a benefit from our new Energy-as-a-Service offering. We use our own new mtu technologies, our system expertise and our global network of partners and service locations to offer our customers an efficient and reliable energy supply on their way to climate neutrality. With SDCL, we have a strong financial partner on board that has successfully developed and financed clean energy, energy efficiency and decentralised energy infrastructure projects since 2007.”

Rolls-Royce to step up hydrogen content in mtu power generators

Rolls-Royce says it is further developing its mtu gas engine portfolio for power generation and cogeneration to run on hydrogen as a fuel and, thus, enable a climate-neutral energy supply.

Generation sets powered by mtu Series 500 and Series 4000 gas engines can, today, be operated with a gas blending of 10% hydrogen, but, beginning in 2022, operation with a hydrogen content of 25% will be possible, the company said.

Perry Kuiper, President Sustainable Power Solutions at Rolls-Royce Power Systems, said intensive tests on test benches and pilot installations at customer sites in 2022 will lead to Rolls-Royce continuously marketing new mtu Series 500 and Series 4000 gas engines beginning in 2023 for use with up to 100% hydrogen, and, on a design to order basis, conversion kits to allow already installed gas engines in the field to run on 100% hydrogen.

Last month, Rolls-Royce and FLANDERS signed an MoU to develop hybrid mining truck retrofit kits for hybridising mining trucks with mtu engines, batteries and hybrid control systems.

Andreas Görtz, Vice President Power Generation at Rolls-Royce Power Systems, said: “The decarbonisation of power generation requires reliable, flexible, but also climate-neutral, power plants to supplement the fluctuating generation from wind and sun. We assume that natural gas will initially be the primary fuel in the development of the hydrogen ecosystem, but we see hydrogen as technically and economically possible. That is why we continue to develop our gas engines for use with green hydrogen – whether as a 10 or 25% admixture or for 100%.”

Rolls-Royce says fuel cells powered by 100% green hydrogen can also play an important role in future energy supply in combination with renewable energies.

At its Friedrichshafen headquarters, Rolls-Royce’s Power Systems division has installed a 250 kW fuel cell demonstrator, which will be used to test and present future CO2-free energy systems to customers. The entire hydrogen ecosystem, including the infrastructure for supply, conversion, test benches and future production, is also being mapped in the company’s own plants, thus building up expertise, it said.

Rolls-Royce’s Power Systems division, through its climate protection program, “Net Zero at Power Systems”, has set itself the target of saving 35% of greenhouse gas emissions by 2030 compared with a 2019 baseline using new technologies.

This near-term target plays an important role in the Rolls-Royce Group’s ambition to achieve carbon neutrality by 2050 at the latest, it said.

In addition to new technologies, a key element in achieving these targets is the certification of key mtu engine products to run on sustainable EN 15940 fuels such as e-diesel and second-generation biofuels as early as 2023, the company added.
