Thermal energy storage will almost certainly play a big role. Germany constructed a test facility in 2017 focused on reducing the cost of these types of plants, and there are already dozens in operation in other countries. Germany is also making a major push for in-home battery installations (recently surpassing 100k units, up from around 5k units in 2013).
