Advancements in technology have made it possible to use cheap electricity and heat storage to reduce fuel burning and carbon dioxide emissions. This combination is particularly beneficial for wind power investments, as it can create demand for electricity during cheaper periods, thereby increasing overall prices. Vantaa Energia has recently announced plans to build the world’s largest seasonal heat storage facility in Vantaa, demonstrating their commitment to promoting green energy transitions.
The investment, totaling EUR 200 million, involves constructing a massive water tank in the bedrock of Kuusikkomäki in Vantaa, along with two electric boilers. Once completed in 2028, the facility will be capable of storing 90 gigawatt hours of thermal energy, enough to heat a medium-sized Finnish city for up to a year. This initiative follows in the footsteps of other heat storage projects like the one completed by Helen in the old oil caves of Mustikkamaa.
Finland’s energy system faces challenges due to the variability in electricity production, especially with the increase in wind capacity. However, advancements in technology have enabled the electrification and storage of heat production using affordable electric boilers. Cheap electricity can now be used to heat water on an industrial scale and store it efficiently, marking a significant shift away from traditional methods of heat production.
The combination of cheap electricity and heat storage not only benefits wind power investments but also reduces fuel burning and carbon dioxide emissions. With over seven billion euros in pending investments for transitioning away from fossil fuels and adopting sustainable energy solutions, Finland is making progress towards achieving its climate goals, including carbon neutrality by 2035. Various innovative solutions, such as electrification and storage of heat production, are crucial for this transition.
Overall, this winning combination between cheap electricity and affordable heat storage can lead to increased demand for electricity during cheaper periods and higher overall prices for electricity producers. It can also make wind power more profitable while reducing fuel burning and carbon dioxide emissions. With ongoing advancements in technology and growing demand for sustainable energy solutions, Finland is well-positioned to continue its progress towards achieving its climate goals through innovative solutions like this one by Vantaa Energia.
