The reason why is clear: the world needs to decarbonise in order to mitigate climate change. The big question is how can utilities decrease CO2 levels while maintaining sufficient electricity generation capacity? The answer is that renewables – solar and wind in particular – will form the baseline for power production in the future, but their intermittent nature means that flexible solutions are needed for balancing. These include energy storage solutions for hour-level firming and dispatchable gas engines for unlimited periods of firming.
The good news is that the technologies for replacing fossil fuels already exist today. Power-to-X is a technology that can turn excess wind and solar electricity into carbon-neutral fuels such as synthetic methane and methanol or green hydrogen using only water, air and electricity as raw materials. Power-to-X is one of the key components for reaching 100% renewable energy and achieving truly carbon-neutral electricity generation. Wärtsilä has several years of experience of working with Power-to-X technology and has established close to ten partnerships to further explore this highly promising area.
Green hydrogen will also play a major role in developing future fuels. Currently, it can be used as a blend with natural gas or as a base for producing other renewable synthetic fuels such as methane or methanol. In the future, it is possible that pure hydrogen will also be used as a fuel.
At Wärtsilä, we want to ensure that our engines run efficiently and reliably regardless of which fuel becomes the leading choice. Whatever the future holds, Wärtsilä’s engines will be able to handle it – so you can invest in a more sustainable future with full confidence today.
