The document posits that EOR is currently the only viable private-market driver for carbon capture and storage (CCS) infrastructure due to its profitability compared to saline storage. It suggests that EOR can lower CCS costs through 'learning by doing' and provide a foundation for 'stacked storage,' where existing pipelines and wells are repurposed for saline reservoirs. The author notes that while EOR is a useful starting point, its global capacity (140 billion tonnes) is insufficient to meet the IPCC's 1.5°C goals, which may require storing up to 1.2 trillion tonnes of CO2, necessitating a transition to the much larger capacities available in saline formations.

The document highlights that just 1% of Switzerland's estimated superhot rock geothermal resource could provide 20 GW of energy capacity, generating over 167,836 GWh of electricity. This amount is more than three times the country's 2021 electricity consumption of 66,039 GWh. Utilizing this resource could theoretically replace all coal and gas used for electricity production, reducing carbon emissions by approximately 3 megatonnes, which represents 10% of Switzerland's Nationally Determined Contribution (NDC) goal. Additionally, the technology could eliminate the need for all natural gas and electricity imports, improving energy independence. Superhot rock geothermal is noted for its high energy density, requiring roughly 12 km² of land per 1 GW, significantly less than solar (180 km²), natural gas (160 km²), offshore wind (520 km²), or biomass (14,000 km²).

The briefing assesses synthetic natural gas (SNG), produced from electrolytic hydrogen and captured carbon dioxide, concluding it is an inefficient decarbonization tool. While SNG can utilize existing natural gas infrastructure, its production is energy-intensive and costly, with landed costs in Northwest Europe estimated at 4 to 9 times the wholesale price of natural gas. The author contends that SNG creates a 'value trap' by consuming clean hydrogen that should be prioritized for sectors where no other decarbonization options exist. Furthermore, the document notes that replacing 20% of 2023 EU LNG imports with SNG would require approximately 12 million tons of clean hydrogen and roughly 17% of total U.S. electricity production.
