Yellow Project is the HAM Group commitment to the construction of CNG-LNG service stations in confined spaces.

The construction of a gas station implies the installation of large equipment, such as the tank, which requires a large area of free space, respecting all the established security measures, which ends up reducing the useful space for the installation of LNG (heavy vehicles) and CNG dispensers (passenger car and trucks).

HAM Criogénica, together with HAM Group’s R&D team, has been in charge of the development of the Yellow Project, which proposes the burial of the gas tank under the circulating area of the service station, thus allowing the installation of a large storage volume without impacting the gas station circulation flows, thus providing a larger and safer surface. All equipment has been designed and manufactured in HAM Group’s facilities and those of Vakuum, a HAM Group company specialised in the design, production of semi-trailers and mobile units for the transport of LNG and air gases, following the latest innovations and quality regulations, as well as EU and ASME design.

The first CNG-LNG service station to be part of the Yellow Project is the new gas station that HAM Group has designed, built, and commissioned in Irún, Gipuzkoa. It is an ultra-compact gas station, established on an area of land only 310 m2, located in Antxotxipi Kalea 4.

The buried tank of the service station has a capacity of 80 000 litres of LNG, works at low pressures (3 bar), has a submerged pump, and can supply up to 12 000kg/hr of LNG and 10 000 kg/d of CNG. The gas station has a buried coldbox, an ‘on the fly’ conditioning system and allows the installation of up to two dispensers (four nozzles) of LNG and one double dispenser (two nozzles) of CNG.

The CNG-LNG service station, safer and with less necessary safety distances, is monitored remotely, guaranteeing its perfect operation and allowing any incident to be solved quickly. The design is also compatible with international ISO standards and, especially, with French standards 4718, 1413, and 1414.
