Innovations, research and development

In July, Wärtsilä announced a new technology benchmark with the introduction of the marine sector’s first hybrid installation for a bulk carrier. The Wärtsilä HY hybrid power module is designed to ensure the seamless integration and control of the technologies to be installed, with the ship’s various existing power production systems. The integrated solution is expected to deliver a significant reduction in fuel consumption and maintenance costs.

In September, Wärtsilä introduced two new versions of the Wärtsilä 31 engine: the 31SG pure gas engine for marine applications and the 31DF multi-fuel engine for the power generation markets. The Wärtsilä 31SG engine further reduces the total cost of ownership and the environmental footprint for vessels operating in regions where there is a developed gas supply infrastructure. The gas-only focus and lean-burn spark ignition technology allows for further optimisation of the engine’s thermal efficiency, while also lowering greenhouse gas emissions and facilitating adaptations for alternative heavier gas fuels, such as LPG. The Wärtsilä 31SG engine is ideally suited for hybrid applications, since it provides outstanding thermal efficiency. It also enables investment cost reductions that help offset the additional cost of energy storage. The Wärtsilä 31DF engine, in turn, offers unequalled open-cycle efficiency, fuel flexibility, and unparalleled dynamic operational features for markets where gas supply is anticipated but not yet available, or where there are concerns about the availability or price of gaseous fuels.
