Today, efficient technologies are available to produce energy (electricity) from renewable sources. However, renewable energies (particularly sunlight and wind) are intermittent. This means that having a society based only on renewable energies is very difficult (even not possible) without proper storage solutions. Different ways to store this renewable power have been proposed such as « power to gas » (e.g. hydrogen production from water splitting) or « pumped-hydroelectricity » storage. However, those storage solutions are expensive to develop in today’s economy, does not have high return on investment and therefore would significantly increase the cost of renewable power compared to energy produce with fossil fuels. Due to this cost, private companies will not invest money on electricity storage solutions if they cannot earn money with them.
In order to accelerate the developement of storage infrastructures, the cost of storage should not be part of an additional cost for these energies (paid by the electricity producers) but should be largely subsidized or even paid by federal funds. The storage infrastructures would thus be public and belong to Switzerland and could be considered as a long-term solution to guarantee a safe , stable and autonomous swiss electricity production.
