Turning A Farm’s Waste Into Power #VERGE16

All Power Labs promises to turn agricultural and forestry waste from a pure cost to something of value. Their Power Pallet, shown above, has been installed in hundreds of locations worldwide, converts waste into electricity, heat and biochar. Biochar which represents sequestered carbon also makes a great soil amendment, according to Tom Price, Director of Strategic Initiatives for All Power Labs.

In the above video, Price explains how the heating of chunky agriculture and forestry waste in a low oxygen environment creates hydrogen vapor that powers a gas engine which spins a generator creating up to 20 kWh of electricity. The resulting electricity costs, according to All Power Labs’ website is $1.50/Watt, which compares favorably to other alternative fuel sources. An optional feature redirects the heat byproduct of the conversion process for things such radiant floor heating provides further efficiency.

Of course, much of the cost of disposing waste is no longer necessary with this method. And these costs are significant, as Price suggests that it can cost $1,500 per acre to clear a California orchard of waste. Price points out that All Power Labs customers are a varied bunch from individuals to cooperatives. And, from a grid perspective, it looks like any other distributed power source (e.g. solar), so it ties into the existing grid so all can benefit from its electricity production.

The potential benefits of converting biowaste to energy extends to forestry. Their Powertainer PT150 model, set for a Q4, 2017 release, is an alternative to controlled burns for forest thinning. Bringing the power generation closer to the fuel source, it promises a way to generate electricity while creating a more economical way of preventing forest fires, as described in this California Agriculture article (PDF).

Another validation of All Power Labs approach is New Holland’s recent announcement of a methane-powered tractor that can use agriculture waste and cow-produced methane as its power source. Like All Power Labs, New Holland is trying to help farmers become more energy independent, while reducing pollution. And although All Power Labs headquarters is in one of the most dense and urban cities in the U.S., it is an appropriate place for it to call home, since, if there are, “Cows in Berkeley“, then waste to power makes perfect sense.¹
