By intelligently analyzing these emerging factory and supply chain data, ML can lower industrial emissions by helping industry in the following ways: switching to low-carbon fuel sources ; optimizing heating, ventilation, and air conditioning (HVAC) systems; improving production quality and efficiency; predicting equipment failures ahead of time; facilitating discoveries in material science and chemical engineering; designing for more efficient material use; and streamlining supply chains.
Nonetheless, improving industrial emissions requires the availability and sharing of high-quality data (which is often proprietary to firms), as well as the alignment of firms' incentives with actually reducing emissions instead of simply producing more goods at a lower cost. In addition, ML is most useful when factory processes or complex supply chains can actually be adjusted accordingly, and when objective functions are clear.
Machine Learning Application Areas
Optimizing supply chains
- Freight consolidation: Optimizing the shipping and transportation of goods across today's globalized supply chains is a complex, multifaceted challenge – especially for perishable goods. Bundling shipments together through freight consolidation can dramatically reduce the number of trips and associated GHG emissions. ML can optimize complex relationship between the various dimensions involved in shipping decisions, such as shipment mode and origin-destination pairs.
- Goods demand forecasting: The production, shipment, and climate-controlled warehousing of excess products is a major source of industrial GHG emissions. ML may be able to mitigate overproduction and/or the overstocking of goods by improving models for forecasting consumer demand, especially for perishable goods or "fashionable" items that quickly become obsolete.
- Greenhouse gas emissions mapping for supply chains: While some factories release publicly-available data on their emissions, this data is not available (or is misreported) in many cases, especially in emerging markets. ML can help map greenhouse gas emissions using a combination of remote sensing and on-the-ground data, leading both consumers and upstream suppliers to make greener decisions in sourcing products.
Developing cleaner products and materials
- Accelerated science for clean energy technologies: Designing new materials is important for many applications, including concrete and steel alternatives, energy storage via batteries, and solar/chemical fuels. ML can help suggest promising materials to try, thereby speeding up the materials discovery process.
- Generative design: ML-enabled 3D design software can can help create new designs for physical structures that reduce the need for carbon-intensive materials – especially cement and steel.
- Additive manufacturing: Novel additive manufacturing techniques such as 3D printing allow for the production of unusual shapes that use less material and/or more carbon-friendly types of material, but may be impossible to produce through traditional manufacturing methods. ML can improve the algorithms controlling the printing process, leading to more faster and more accurate production.
Optimizing factory operations
- Electricity supply and demand forecasting: The supply and demand of power must both be forecast ahead of time to inform industry's electricity planning and scheduling, thus helping factories optimize their electrical usage for renewable energy. ML can help make these forecasts more accurate, improve temporal and spatial resolution, and quantify uncertainty.
- Demand response: By accurately predicting and quickly responding to changes in the supply of electricity, factories can reduce their electricity usage during peak periods and diminish the need for utilities to resort to fossil fuels. ML can assist with helping factories optimize the timing of their production to take advantage of inconsistent solar and wind power.
- Methane leak detection: Fertilizer factories and other chemical plants often leak methane, a powerful greenhouse gas. ML can help detect and prevent these leaks.
- Adaptive systems control: Most factories today rely on complex networks of disconnected production equipment, leading to inefficiencies in control systems such as temperature control, power usage, and material flow. ML techniques such as image recognition, regression trees, and time delay neural networks can help optimize the control and efficient automation of industrial systems.
- Predictive maintenance: Quickly detecting machinery faults can help reduce electricity and materials waste. ML can help detect faults in real time from machinery sensor data, or even forecast them ahead of time to enable preemptive repair or replacement.
