| Piston power and gensets Carbon capture for mtu gas engines


Rolls-Royce, ASCO Carbon Dioxide Ltd (ASCO), and Landmark Power Holdings Limited (LMPH), have signed a memorandum of understanding aimed at developing scalable solutions for clean power generation with carbon capture from mtu gas reciprocating engines.


“Power generation is a highly attractive, growing market segment and an area of strategic focus for Rolls-Royce, where partnerships can help further grow market position and broaden its power generation offering,” said Tobias Ostermaier, President Stationary Power Solutions at Rolls-Royce Power Systems.


The plan is to make the captured CO2 available for use in various industries such as


food production, e-fuels, sustainable aviation fuel (SAF), cement and plastics production. The captured CO2

should permanent sequestration be preferred, the partners say.


Rolls-Royce is contributing its experience in the field of decentralised power generation to the partnership through its Power Systems division which includes the mtu product portfolio. The contribution of LMPH, a developer of high- efficiency combined heat and power projects, is principally its patented FLEXPOWER PLUS® concept. This incorporates organic Rankine cycle systems, as well as carbon capture, see diagram. ASCO, which has “over 50 years of experience


in developing and building carbon capture/CO2 recovery plants” and will be “providing valuable insights and solutions from the carbon capture industry.”


“We are convinced that CO2 capture and storage

systems in combination with our mtu gas gensets are an important building block on the way to Net Zero,” says Tobias Ostermaier. “As a complement to renewable energy sources, internal combustion engines can already provide clean, cost-effective and extremely reliable power generation.” The technology to be offered via the partnership will see its initial deployment in a first-of-its-kind £30 million 10 MW decarbonised flexible power generation and carbon capture


Rolls-Royce emergency backup power for Colorado datacentre


Rolls-Royce has received an order from its distributor Smith Power Products to provide two 1500 kW mtu Kinetic PowerPacks (KPPs) for NOVVA Data Centers. The two KPPs will provide emergency backup power for an expansion at the company’s Colorado Springs datacentre. The Power Systems division of Rolls-Royce has already delivered over 50 MW of mtu emergency diesel gensets for NOVVA’s various locations through Smith Power Products. The KPP’s battery-free design and ability to run on hydrotreated vegetable oil (HVO)/renewable diesel “aligns well” with NOVVA’s environmental

approach, says Rolls-Royce. Additionally, Smith Power will be providing a selective catalytic reduction system to nearly eliminate the emission of nitrogen oxides when the system is running. Unlike static UPS systems where batteries are required to pick up the immediate load before the diesel engine fires up, the KPP is considered a dynamic UPS system. It uses stored kinetic energy from the flywheel to power the synchronous machine and provide an immediate response until the engine comes online seconds later to take over the load.

The contract is also a first of a kind. “In principle, this agreement guarantees a stable and reliable supply of tens of thousands of tons of food- grade CO2


Caterpillar extends hydrogen offering


Caterpillar has added Cat CG260 gas gensets to its portfolio of commercially available machines capable of running on hydrogen fuel.


The12- and 16-cylinder versions of the Cat CG260 are approved to operate on gas containing up to 25% hydrogen by volume. The CG260 provides up to 4.5 MW of electric power for continuous, prime and load management requirements. In addition, Caterpillar offers retrofit kits to update CG260 generator sets already installed with these same hydrogen capabilities.


With the latest addition, Caterpillar now offers a gas generator set portfolio ranging from 400 kW to 4.5 MW offering hydrogen blending opportunities through factory-installed hardware and retrofit kits for the CG132B, CG170B, CG260 and G3500H platforms.
