PlanetWest Offers a New Carbon Capture Equation for Climate Stabilization
Patent-pending MIDAC technology proposes a decentralized approach to capturing black carbon and particulate pollution in dense urban environments
[CITY, STATE — DATE] — PlanetWEST today announced a new approach to carbon management designed around a simple premise: climate stabilization may require not only preventing future emissions and removing atmospheric CO₂, but also addressing highly concentrated short-lived climate pollutants where they are generated and accumulated.
PlanetWEST's patent-pending MIDAC™ (Mobile Intelligent Direct Air Capture) platform is designed as a distributed solid-carbon capture system capable of operating on mobile platforms. Rather than relying exclusively on large, stationary facilities, MIDAC is being developed to capture black carbon, PM2.5, and other fine particulate matter as vehicles move through urban environments.
The approach is intended to complement conventional carbon-removal technologies by addressing a different physical challenge: the concentration of solid particulate pollution in the places where people live, work, and travel.
Rethinking the Carbon Capture Equation
Conventional Direct Air Capture (DAC) is primarily designed to remove gaseous CO₂ directly from ambient air. Because atmospheric CO₂ is highly dilute—approximately 420 parts per million—DAC systems must process substantial volumes of air to isolate the target gas. The IEA identifies both energy requirements and the movement of large quantities of air as important considerations in the development and deployment of DAC technologies.
PlanetWEST's MIDAC concept approaches atmospheric cleanup from a different direction.
Instead of attempting to capture a uniformly distributed atmospheric gas across a large stationary footprint, MIDAC is designed to target solid carbon and particulate pollutants in locations where concentrations can be significantly higher, including dense traffic corridors, ports, industrial districts, highway interchanges, and other urban pollution hotspots.
"The climate challenge is not one-dimensional," said [NAME, TITLE]. "We need to reduce emissions, remove atmospheric CO₂, and address the pollutants that are already affecting the air people breathe. MIDAC represents our effort to introduce another tool into that equation—one designed around mobility, concentration, and distributed deployment."
Five Dimensions of a Different Approach
1. The Energy Equation: Utilizing Existing Vehicle Airflow
Traditional DAC systems move large volumes of ambient air through capture systems and subsequently regenerate the capture media. Depending on the technology, this can require substantial electricity and thermal energy.
MIDAC is being designed for integration with moving vehicles, including commercial trucks, transit buses, and other high-mileage platforms. The system concept utilizes airflow already generated as a vehicle travels, potentially reducing the need for dedicated large-scale air-moving infrastructure during the capture process.
This creates the possibility of deploying atmospheric capture through existing transportation infrastructure rather than constructing an entirely new network of stationary facilities.
2. Targeting a Powerful Short-Lived Climate Pollutant
CO₂ remains the principal long-lived greenhouse gas targeted by conventional DAC. MIDAC instead focuses on black carbon and other particulate pollutants.
Black carbon is a short-lived climate pollutant produced primarily through incomplete combustion. It absorbs solar radiation and contributes to atmospheric warming, while also being associated with harmful particulate pollution.
Unlike CO₂, however, black carbon does not have a single universally accepted GWP equivalent. Scientific estimates vary substantially depending on the metric, geographic conditions, and time horizon used to evaluate its climate impact.
PlanetWEST's strategy is therefore not to claim that black carbon simply replaces CO₂ as a carbon-removal target, but to address a complementary class of pollutants whose atmospheric lifetime and localized effects create opportunities for near-term climate and air-quality benefits.
3. Hyperlocal Concentration vs. Dilute Ambient Air
Atmospheric CO₂ is relatively evenly distributed throughout the atmosphere at approximately 420 ppm. Black carbon and particulate pollution, by contrast, can be highly localized around combustion sources and urban transportation corridors.
MIDAC is designed around this difference.
By deploying mobile capture systems throughout cities, PlanetWEST envisions targeting areas where particulate pollution is concentrated rather than treating atmospheric air as a uniformly polluted resource.
Potential deployment environments include:
Dense urban traffic corridors
Highway interchanges
Ports and freight corridors
Industrial districts
Airports
Municipal and commercial vehicle routes
Other identified particulate pollution hotspots
The objective is to bring capture technology directly to the locations where it can potentially have the greatest local impact.
4. Distributed Deployment Instead of a Large Urban Footprint
Large stationary carbon-removal facilities require dedicated land, infrastructure, energy connections, and transportation or storage systems. These requirements can become particularly challenging in densely populated metropolitan areas where available land is limited and expensive.
MIDAC proposes a different deployment model.
By integrating capture systems into existing vehicle fleets, PlanetWEST envisions a distributed network that can move throughout an urban area without requiring a dedicated parcel of municipal land for each capture unit.
Captured material could potentially be collected through existing fleet maintenance and depot infrastructure, creating a distributed approach to atmospheric cleanup.
5. Climate Action With Local Air-Quality Benefits
One of the distinguishing characteristics of solid particulate capture is its potential to address both climate and air-quality concerns.
Black carbon and PM2.5 are components of particulate pollution that can have significant human-health implications. EPA identifies black carbon as an air pollutant that contributes to atmospheric warming.
A mobile capture network designed to operate at street level could therefore pursue two objectives simultaneously: reducing short-lived climate pollutants and helping reduce particulate pollution in environments where human exposure occurs.
A Complement to Conventional Carbon Removal
PlanetWEST does not position MIDAC as a replacement for conventional CO₂ removal.
Rather, the company sees mobile solid-carbon capture as a complementary layer of climate infrastructure.
Conventional DAC can address atmospheric CO₂ and provide a pathway for balancing difficult-to-eliminate emissions and legacy carbon. MIDAC is designed around a different target: solid particulate pollution that is concentrated in specific environments and can be encountered at street level.
Together, these approaches illustrate a broader carbon-management strategy in which different technologies address different forms of atmospheric pollution.
The PlanetWEST Vision
PlanetWEST believes climate stabilization will require more than a single technology or a single metric.
Reducing greenhouse-gas emissions remains essential. Removing atmospheric CO₂ will play an increasingly important role in addressing legacy emissions and achieving net-zero pathways. At the same time, short-lived climate pollutants and harmful particulate matter represent an opportunity for targeted intervention that can produce benefits closer to where people live and work.
MIDAC is PlanetWEST's effort to pursue that third dimension.
By combining mobility, intelligent deployment, solid-carbon capture, and existing transportation infrastructure, PlanetWEST is developing a new model for decentralized atmospheric cleanup—one intended to bring carbon capture out of the industrial facility and into the environments where pollution is concentrated.
