The early dropĬontained most of these, so the ground beneath the tree was cleanedĪnd the men and older boys climbed the tree with poles and knockedĭown the good acorns. Harvest was done so as to avoid wormy acorns. Oak was avoided, as it produced poor quality flour. Threaded onto strings and hung up to adequately dry. Had to be shelled first, and there are pictures of them being In nutrition and highest in moisture of the commonly eaten acorns,Īnd required the most effort to dry. In annual abundance, and smaller in size. Protein, low in moisture and otherwise good, but are more inconsistent Nutrition and good quality flour when pounded. With significant tannins (insect repellent), low moisture, good Tan oak and black oak both have large acorns, Most species of oak were used, but they vary in nutrition, moistureĬontent and texture. The species of acorn stored also factors into storage options. So granaries might be located where prevailing breezes minimized And it can also come from the air as fog, It can alsoĬome from the sky, so granaries in rainy areas were thatched or Or had a moisture barrier such as a stone below them. Moisture comes from the ground, so most granaries were elevated Moisture then became the remaining design issue. The food, or repel pests from eating through. Were dealt with by constructing or lining the granary with toughĪnd/or bitter, aromatic plants which either mask the smell of Moisture a bigger factor in the rainy north. To climate, with rodents being a big factor in the desert, and Storage requires overcoming several factors: moisture (mold, Silos from the great Central Valley, the mountains of the northĪnd east, and parts of the desert south are illustrated here. In areas where they were a smaller part of the diet. Stored in tight baskets hung inside the houses, as were acorns Pine nuts and mesquite beans supplemented or took the place ofĪcorns, and were stored in similar granaries. This was the main source for plant calories. Meat and fishĪre thin sliced and hung, berries and cooked roots are smashedĬalifornia Native Peoples stored many different kinds of seeds,īut are best known for storing acorns. Meat, fish, berries, tubers and bulbs all requireĮxtensive work to dry before they can be stored. Seeds have an additional advantage in that theyĪre designed to be dormant for long periods of time, so are less Them one of the food resources suitable for storage along with Seeds ripen but once a year, and often in abundance. It is led by Pale Blue Dot Energy (a wholly owned subsidiary of Storegga) with Shell working as the Technical Developer for the Acorn CCS Project.Acorn Granaries of California by Norm Kidder The project is funded and supported by industry partners (Storegga, Shell, Harbour Energy and NSMP), the UK and Scottish Governments and the European Union. This first phase of Acorn CCS offers a low capital cost start, that can be delivered by the mid 2020s – establishing the critical CO 2 transport and storage infrastructure required for the wider Acorn build-out including Acorn Hydrogen and the import of CO 2 to St Fergus from ships at Peterhead Port and from Scotland’s industrial Central Belt.ĭesignated a European Project of Common Interest (PCI) Acorn is an important catalyst for clean growth opportunities in Scotland and in regions where CO 2 transport and storage is limited, Acorn can help transform our carbon intensive industries into low carbon industries and sustain jobs. With this important pipeline infrastructure already in place, Acorn CCS can get started using existing CO 2 emissions– captured directly from the gas processing units at the St Fergus gas terminal. Acorn CCS is a carbon capture and storage project specifically designed to overcome one of the acknowledged blockers to CCS deployment in the UK – the high capital costs involved in getting started.īased at the St Fergus gas terminal in North East Scotland, Acorn CCS can repurpose existing gas pipelines to take CO 2 directly to the Acorn CO 2 Storage Site.
