A startup plans to build a new type of fuel-producing plant in California’s fertile Central Valley that would, if it works as hoped, continually capture and bury carbon dioxide.
The facility, developed by Mote of Los Angeles, would rely on the mounds of agricultural waste produced on the state’s sprawling almond orchards and other types of farms. It would heat leftovers like tree trimmings and fruit pits to temperatures above 1,500 ˚F, hot enough to convert the biomass into hydrogen and carbon dioxide.
Mote plans to separate out the carbon dioxide and pump it deep underground into saline aquifers or retired oil wells near the plant. The hydrogen would be sold to serve the state’s growing fleets of emissions-free buses and trucks.
The process should permanently store away the carbon captured by the plants as they grow. And the hydrogen would defray the high costs of the process.
Mote says its facility would be the first to convert biomass to hydrogen while capturing the carbon emissions. But it’s among a growing number of efforts to commercialize a concept first proposed two decades ago as a means of combating climate change, known as bioenergy with carbon capture and sequestration, or BECCS.
Such operations could remove greenhouse gas from the atmosphere over time, even as they provide low- or no-emissions replacements for fossil fuel. But there are serious challenges to doing it affordably and in ways that reliably suck down significant levels of carbon dioxide.
Dan Sanchez, who runs the Carbon Removal Lab at the University of California, Berkeley, says the process that Mote intends to use, known as biomass gasification, is technically difficult and expensive. It requires careful pre-treatment of the waste and cleaning of the resulting gases. And gathering up the fuels from scattered farms or forests will be complicated and costly.
In addition, the company’s longer-term prospects could be constrained by the lack of infrastructure for moving around and storing the resulting gases, as well as limited demand for the high-cost variety of hydrogen it plans to produce.
But Mote’s plant might be a particularly effective approach to BECCS because the resulting fuel is carbon free, while other types of plants produce fuels that release some amount back in the end.
And Mac Kennedy, the company’s chief executive, says the facility could become profitable within a few years by taking advantage of state subsidies for low-carbon fuels and federal tax credits for carbon storage. He hopes to eventually build more plants across California and beyond, potentially tapping into other fuel sources like trees removed from forests, whether in the aftermath of wildfires or in the hopes of preventing them.
BECCS is a loosely defined technology that can include facilities running on wood chips, switchgrass, or municipal waste, and producing electricity, ethanol, or so-called synthetic fuels that can power today’s cars, trucks, and planes.
The concept has seized a growing share of attention in research and policy discussions as climate models increasingly find that the only way to avoid very dangerous levels of warming this century is to suck vast amounts of greenhouse gases from the atmosphere.
Plants and trees do a great job at that, but when they die, rot, or burn, much of the carbon is returned to the air. Various BECCS schemes promise to “make sure it’s permanently out of the atmosphere,” says Roger Aines, who leads the Carbon Initiative at Lawrence Livermore National Laboratory.

The hope is that these operations can be at least carbon neutral, adding no more greenhouse gases they remove. But some promise to draw down much more than is generated, achieving what’s known as negative emissions.
In 2018, the UN’s climate panel concluded that limiting warming to 1.5 ˚C over preindustrial levels could require the removal of as much as 8 billion tons of carbon dioxide per year through BECCS by 2050. Estimates for the technology’s carbon removal capacity vary widely, ranging

Stitching together the grid will save lives as extreme weather worsens
The blistering heat waves that set temperature records across much of the US in recent days have strained electricity systems, threatening to knock out power in vulnerable regions of the country.
The electricity has largely stayed online so far this summer, but there have been scattered problems and close calls already.
Heavy use of energy-sucking air-conditioners is the biggest problem. But intense heat can also reduce the output of power plants, blow transformers, and force power lines to sag. Severe droughts across large parts of the country have also significantly reduced the availability of hydroelectric power, according to the North American Electric Reliability Corporation (NERC).
It’s unlikely to get better soon. A number of grid operators may struggle to meet peak summer demand, creating the risk of rolling blackouts, the NERC report notes.
The nation’s isolated and antiquated grids are in desperate need of upgrades to keep the lights, heat, and air-conditioning on in the midst of extreme weather events that climate change is making more common, severe, and dangerous. One clear way to ease many of these issues is to more tightly integrate the country’s regional grids, stitching them together with more long-range transmission lines.
If electricity generated in one area can be more easily shared across much wider regions, power can simply flow to where it’s needed at those moments when customers crank up air-conditioners en masse, or when power plants or fuel supply lines fail amid soaring temperatures, wildfires, hurricanes, or other events, says Liza Reed, a research manager focused on transmission at the Niskanen Center, a Washington, DC, think tank.
The problem is it’s proved difficult to build more long-range transmission and grid interconnections for a variety of reasons, including the permitting challenges of erecting wires through private and public lands across cities, counties, and states and the reluctance of local authorities to forfeit control or submit to greater federal oversight.
The case of Texas
The unreliability of the US grid is not a new problem. Severe heat and winter storms have repeatedly exposed the frailty of electricity systems in recent years, leaving thousands to millions of people without power as temperatures spiked or plunged.
One of the fundamental challenges is that the grids today are highly fragmented. There are three main electricity networks within the US: the Eastern Grid, the Western Grid, and the Electric Reliability Council of Texas (ERCOT). But there are numerous regional transmission organizations within those first two systems, including the California Independent System Operator, Southwest Power Pool, PJM Interconnection, New York ISO, and more.
These grids form a complex web of networks operating under different regulators, rules and market structures, and often with limited connections between them.
A variety of regional transmission organizations oversee different parts of the nation’s aging and fragmented grids, which operate under different rules and with often limited connections between them.
ERCOT is especially isolated, in part because of the desire among local politicians, citizens, and power companies to avoid added competition, the hassle of following other states’ rules, and oversight from the Federal Energy Regulatory Commission (FERC). But the state offers a case study in why that can be a serious problem amid increasingly harsh climate conditions, Reed says.
The Texas grid operator pleaded with customers several times earlier this month to cut electricity use as blistering summer temperatures created demand surges that threatened to outstrip supply and require rolling blackouts. Low wind conditions, cloud cover, and outages at fossil-fuel power plants added to the strains.
