The Dutch gas field Q16 Maas with onshore surface installations is currently under consideration, as part of a Dutch programme (see page 6) for the development of a CO2 buffer for CO2 utilisation.
The 2 800 m deep Triassic sandstones of the gas reservoir have an estimated storage capacity of about 1.8 Mt CO2. This large buffer will offer storage for industrially produced CO2 in the wintertime and back production in summertime for greenhouse horticulture companies and thus guarantee the security of supply with increasing demand for CO2, which is commonly used in greenhouses to enhance plant growth.
Underground buffering is the only solution considering the scale of the buffer capacity needed. Such buffer storage could also be necessary for other uses of CO2 and for collecting emissions before sending them to larger storage sites, including offshore. Site specific data will be used to study the conditions of back production of CO2 (for use or transfer) and to assess the economic viability of implementing such facilities.
