Fats are central to cooking, from cordon bleu to the hasty sandwich, and there's nothing that quite matches animal-derived fats in the kitchen. Unfortunately, animal-derived fats have a substantial carbon footprint and other ethical problems, while plant-derived fats, such as palm oil, are not without their own well-known issues. Savor, a California-based startup, have developed a thermochemical process to produce fats from carbon dioxide, hydrogen, and oxygen that are identical to animal-derived fats. Recently, they have developed a pre-commercial butter that is a close match for traditional, animal-derived butter while being more sustainable. The process doesn't release any greenhouse gases, and it uses no farmland and less than a thousandth of the water that traditional agriculture does.
