For a factory, farm or hotel that runs on diesel, LPG or coal, every delivery is fuel that was extracted, shipped and bought before it is burned. Residue is already there. Jenja is designed to turn it into fuel gas, so a site could burn less of the fossil fuel it buys today.
A generator running on diesel, a boiler fed with LPG or coal, power from a grid that burns fossil fuel: all of it has to be bought, and fuel has to be delivered. And every time it burns, it releases carbon that lay underground for millions of years, adding new carbon dioxide to the air. Diesel exhaust also causes lung cancer.38
Worldwide, burning fossil fuels and making cement released about 10.3 billion tonnes of carbon in 2024, and by 2025 the carbon dioxide in the air had risen to an estimated 53 percent above its level before industrialisation.39
Fossil fuels also foul the air people breathe. Researchers estimate that phasing them out could prevent about 3.6 million deaths a year from outdoor air pollution worldwide.40
The same site may hold something it does not use: crop residue, digestate or other organic leftovers.
Jenja is designed to turn that residue into fuel gas on site. In its power configuration, the gas is designed to drive a generator for electricity; in its heat configuration, a boiler for heat.
Less fossil carbon. Every litre of diesel, every kilo of LPG or coal Jenja could replace is fossil carbon that this site no longer releases into the air.
Less diesel exhaust. Every litre of diesel the site no longer burns is diesel exhaust that never reaches the air around it.
Carbon that circulates. The carbon in residue came from plants, which took it from the air as they grew. Fossil fuel adds carbon that was out of circulation for millions of years. Plant carbon still spends time in the air before new growth takes it back up, and how long depends on how fast the plants grow back.41
How large the gain is depends on the fuel replaced and on what would otherwise have happened to the residue. A real site will put a number on it.
The next step is a site: Jenja running on its own residue, its power and heat measured, and the fuel it replaces named. That is when this pathway gets its number.
