Each pathway follows the chain from what Jenja is designed to produce to the change it could make on the ground.
Two pathways about what Jenja's energy could do for the people who use it.
Designed to produce power and heat on site, in its power configuration.
In its power configuration, Jenja is designed to turn residue the site already holds into its own electricity and heat, so supply no longer depends on a fuel delivery.
Households, clinics, water pumps, workshops and cold storage beyond a working grid.
No supply at all, a diesel generator, or grid power that cannot be relied on.
Designed to produce useful heat.
Heat from Jenja could drive cooling, drying and the pasteurisation of water.
A dairy, a market, a clinic, a port, and households without safely managed water.
The electricity or fuel that would otherwise be used for cooling, or for heating and boiling water.
Designed to produce fuel gas, used for power and heat.
Where a site buys diesel, LPG, coal or fossil-based grid power, Jenja's power and heat could replace part of it, and with it part of the fossil carbon and diesel exhaust.
Sites that buy fossil fuel, and the climate, where that fuel is no longer burned.
The named fuel at the site: diesel, grid power, LPG or coal.
Designed to take difficult residues, such as ash-rich fuels.
The residue could become fuel instead of a disposal cost. Its ash still has to be managed.
Sites that pay to dispose of residue, and, where it is now burned in the open, the people who breathe the smoke.
The residue's current fate at that site, named: dumping, open burning, landfill, land spreading or incineration.
Not yet known. Whether Jenja leaves a carbon-rich char, and how much, has not been measured.
If part of the feedstock carbon leaves as a stable char, it could stay out of the air for a long time and could help soils.
Soil, where the char is eligible for land use, and the climate, if that carbon would otherwise have returned to the air.
The residue's current fate at that site, named.
Any carbon that stays in a solid is not in the gas. More carbon left in the solid would mean less energy in the gas for power and heat, including for pathways 1 and 2. That is why these benefits are never added together.
The warming figures, the time horizons and the rules for counting biogenic carbon are set out with their sources in the evidence centre, alongside the method.
