Could a Protein Made From Electricity Reduce World Hunger?

What would happen if we could use renewable energy to create food out of electricity and hydrogen? Could we feed the world?

That’s the question a group of Finnish researchers aims to answer. Scientists from the Lappeenranta University of Technology (LUT) and VTT Technical Research Centre of Finland conducted a joint study to produce a single-cell protein by using electricity, hydrogen and carbon dioxide.

That protein, they say, can be used to feed both people and animals. This project is part of a Neo-Carbon Energy research project carried out jointly by the LUT and VTT. The initiative strives to develop renewable and emission-free energy systems.

“It’s not so much different than making beer, but in making beer, of course, you use sugar as the raw material, but in this case we use hydrogen,” VTT Technical Research Centre of Finland senior scientist Juha-Pekka Pitkänen told the Smithsonian.

To make this powder, scientists begin with hydrogen-oxidizing bacteria. It goes into a small bioreactor with water and an electric water splitter, which tears apart the hydrogen and oxygen. The bacteria then consumes the hydrogen.

Following combination with atmospheric carbon and a few other helper substances — like phosphorus, ammonia and inorganic salts — this process produces a powder that is approximately 50 percent protein, 25 percent carbohydrate and 25 percent fats and nucleic acids.

“In the long term, protein created with electricity is meant to be used in cooking and products as it is. The mixture is very nutritious,” Pitkänen noted. “The consistency of the final product can be modified by changing the organisms used in the production.”

Even more amazing, this process is completely portable and environmentally benign. It doesn’t rely on specific agricultural or soil conditions. It requires no sunlight or rain, and the temperature outdoors is irrelevant. And there’s no need for fertilizer or pesticides, meaning there’s no pollution-causing runoff into local waterways.

Researchers believe that, initially, this protein could be used to produce an alternative animal feed. If used in this way on a widespread basis, it would free up the vast acreage of farmland we use today to product crops to feed livestock. It could also help end critical environmental problems like the deforestation of the Amazon rainforest for cropland.

But I’d assert that we ought to be diving straight into step two of the researchers’ plan — using this protein to feed people.

After all, this sounds like a vegan protein source to me. Here’s a way to get those farmed animals out of the equation completely. If we began producing protein using renewable power in every place where food is needed, why would we need livestock at all?

Without all that livestock, greenhouse gases would take a definite downward plunge. This concept just keeps sounding better and better, doesn’t it?  Food from electricity is a potentially game changing discovery.

According to the United Nations Food and Agriculture Organization, 795 million people were chronically undernourished between 2014 and 2016. With one fell swoop, this concept could change all that.

What would the world be like with everyone properly fed and no more need for factory farming? That’s my idea of heaven.

For now, the research team is working to make this process even more efficient. Currently, making food from electricity is about 10 times as efficient as photosynthesis. Even so, protein generation takes approximately two weeks to complete. It needs to be faster to be marketable and competitive.

But the researchers predict substantial improvements in just 10 years. Between this outstanding work and parallel efforts to create lab-grown, cultured meat, one decade may well be the difference between industrialized factory farming and a cruelty-free food system. I’m eager for that day to arrive. Are you?

whats wrong w/ lentils as a source of protien- one cup gives protien in 3 cups meat & its all natural- as God provided it- 100 diff kinds of lentils, & they can be soaked & sprouted too, made into flour for tortillas etc/ pizza dough/ grinded into chutneys & dips galore!! only limit is the immagination :-))

This sounds wonderful, the sooner it can become large-scale mass production the better :-) Even if it only used as animal feed for a while.
