A California-based biotechnology startup has officially launched the world’s first commercially available butter made entirely from carbon dioxide, hydrogen, and oxygen, eliminating the need for traditional agriculture or animal farming. Savor, backed by Microsoft co-founder Bill Gates through his Breakthrough Energy Ventures fund, announced the commercial release of its animal- and plant-free butter after three years of development.
The revolutionary product uses a proprietary thermochemical process that transforms carbon dioxide captured from the air, hydrogen from water, and methane into fat molecules chemically identical to those found in dairy butter. According to the company, the process creates fatty acids by heating these gases under controlled temperature and pressure conditions, then combining them with glycerol to form triglycerides.
Perhaps. But if we really go hard on green energy, we’ll likely have a lot of excess energy in the daytime, so it makes sense to look into alternatives to land and water intensive products (like dairy and beef) that are heavy on electricity. If it’s a more efficient use of land to have solar panels instead of cows eating grass (and solar panels work just as well on farmland as they do in the desert, unlike grass), then it makes a ton of sense even if it spikes electricity consumption.
Butter is rather low volume, so maybe it’s doable. But it’s very hard to compete with self-replicating organisms that have evolved specifically to use the energy sources, materials and conditions that are abundant on this planet. I’d be more more interested if someone had made a plant make butter.
Having a bunch of machinery sit idle waiting for power to be cheap isn’t particularly good use of resources either. We’d be better off trying to store the power.
Storing power is expensive and many energy storage techniques require a lot of resources to produce. The more we move toward solar generation, the more we should plan on being opportunistic with energy when it is plentiful
For example, electrolysis isn’t the most efficient way to store power, but if energy is cheap, it may be better on net to do it opportunistically when there’s excess energy and use that hydrogen for things like producing artificial butter (and perhaps fuel mobile equipment like forklifts and delivery trucks).
Cows aren’t particularly efficient at turning biomass into human food. There’s a ton of waste in the process, and they need a lot of space. A factory doesn’t need to sustain life of an organism, it just needs to turn one set of compounds into another. Maybe it’s not there now, but getting it there will be a lot easier than genetically engineering a much better cow.
