The risk of seasonal mismatches between electricity supply and demand is increasing due to expanded use of wind, solar and hydropower resources. Power system planners are thus in search of low-cost seasonal energy storage options. Seasonal Pumped-Storage (SPS) can provide short, medium and long-term energy storage at a relatively low-cost and provides co-benefits in the form of freshwater storage capacity. Here, we present the first global assessment of SPS potential, using a novel plant-siting methodology and high-resolution topographical and hydrological data. Our results show that SPS costs vary from 0.007 to 0.2 $/m3 of water stored, 1.8 to 50 $/MWh of energy stored and 0.37 to 0.6 $/GW of installed power generation capacity. The estimated world energy storage capacity below a cost of 50 $/MWh is 17.3 PWh, approximately 79% of the world electricity consumption in 2017.

“…For example, compressed air energy storage is being investigated as a more universal energy storage solution than hydro storage, which is limited to areas with suitable geographical conditions. The pores between grains of rock in the earth could potentially store sufficient compressed air to provide seasonal energy storage [7]. In electrochemical energy storage, improvements to battery technology need to be made to keep up with developments in other fields, such as electric vehicles.…”

This editorial accompanies the full launch of the latest new BMC Series journal, BMC Energy. Written jointly by the journal Section Editors, the Chair of the Editorial Advisory Board and the Editor at Springer Nature, this editorial outlines how this new journal plans to serve the energy research community and describes in detail the scope of the work that it hopes to attract. BMC Energy joins a number of new physical science journals that have been launched recently in the BMC Series, each following BMC Series' ethos of openness and inclusivity, aiming to publish quality research that is accessible for all.

“…The technology for gas injection and storage in porous media is well established. Gas is injected into a porous and permeable reservoir formation, such as an aquifer or a depleted hydrocarbon field, via injection wells, and displaces the in-situ pore fluid, usually brine, and spreads out underneath an impermeable caprock (Mouli-Castillo et al, 2019;Heinemann et al, 2018;Edlmann et al, 2019). Since thick salt formations are absent in the Midland Valley, storage in porous media has to be investigated.…”

Scotland is committed to be a carbon-neutral society by 2040 and has achieved the important initial step of decarbonising power production. However, more ambitious measures are required to fully decarbonise all of the electricity, transport and heating sectors. We explore the potential to use the low-carbon GeoEnergy resources and bio-energy combined with Carbon Capture and Storage (BECCS) in the Midland Valley area to decarbonise the Scottish economy and society. The Midland Valley has a long history of geological resource extraction, and as a result, the geology of the region is wellcharacterised. Geothermal energy and subsurface energy storage have the potential to be implemented. Some of them, such as gravity and heat storage, could re-use the redundant mining infrastructure to decrease investment costs. Hydrogen storage could be of particular interest as the Midland Valley offers the required caprock-reservoir assemblages. BECCS is also a promising option to reduce overall CO 2 emissions between 1.10-4.40 MtCO 2 /yr. The Midland Valley has enough space to grow the necessary crops, but CO 2 storage will most likely be implemented in North Sea saline aquifers. The studied aspects suggest that the Midland Valley represents a viable option in Scotland for the exploitation of the majority of low-carbon GeoEnergy resources.
