Decarbonization
What is deep decarbonization? Deep decarbonization refers to eliminating CO2 emissions from a physical process. This involves replacing fossil-fuel combustion with electric devices, particularly in a circular economy. For every 1 kWh (3.6 kJ) of energy used or converted through electric methods instead of burning carbon-containing fuels, approximately 0.8 to 2.2 pounds of CO2 emissions can be avoided. Deep decarbonization and energy efficiency go hand in hand.
For instance, a 100 kW device can prevent 80 to 220 pounds of CO2 emissions per hour by using electric heating instead of fossil-fuel combustion. Similarly, a 10 MW device can prevent 8 to 22 tons of CO2 emissions every hour.
MW decarbonized heating and drying convection.
Industries where deep decarbonization is feasible. Ceramic, Cement, Metal production, Aluminum primary and secondary, Steel, Food and beverage, Ore drying, Chemical, Fuels, Calcining, and any heat-treating operation. Electric energy and Fossil fuel energy costs may be converging. The social cost of CO2 production is already significant and is increasing.
How much CO2 is produced in industrial operations? In 2021, the total excess global CO2 emissions were about 37 Gigatons (Gt). Of this, about 12 GT, or 30%, was made by industrial operations and the rest by transportation and power generation. These are rough estimates.
What is the growth rate of CO2 emissions? Excess emissions increased by over 2.0 Gt from 2020 to 2021 (post-pandemic recovery). Very rough estimates suggest that excess CO2 increased by about 0.4 to 0.9 GT/year over the past 20 years. The annual growth rate of atmospheric carbon dioxide over the past 60 years is about 100 times faster than the natural increases that occurred at the end of the last ice age, 11,000-17,000 years ago.
What was the atmospheric CO2 concentration in 2022? About 421 ppm. The estimate in 2024 is 426 ppm.
What was it in the year 1950? About 281 ppm.
How does this relate to extreme weather? Measuring the rate of increase is essential because it relates to the rate of temperature rise. A clear explanation is here.
Is global warming tied to the increase in CO2? Yes. The GHGs (greenhouse gases) are rising rapidly. This drives several climate-related damages to infrastructure by enabling severe weather events such as very high temperatures, thunderstorms, and lightning. Climate change could trigger significant losses in asset values, harming the US and the global economy. Video. As the planet rapidly approaches the 1.5-degree Celsius warming threshold, scientists warn that rising temperatures are degrading the Earth’s ability to absorb carbon dioxide, threatening to exacerbate climate change. Still, the Earth’s average temperature fluctuates yearly due to natural variability in Earth’s climate systems. To keep warming in check, countries must make steep cuts to emissions in the next few years, with an emphasis on industrial heating and electrifying large kW and MW installations. Contact MHI.
Can CO2 emissions be quickly mitigated? Yes. Switching to electric heating in the industrial sector may be the lowest-cost CO2-reduction strategy per kW (Equipment power capability). 1 MW of electrification of industrial heating that replaces fossil fuel heating methods can save about 0.2- 0.6 tons of equivalent CO2 emissions per hour. Contact MHI.
Is the technology available? Yes.
Compact commercial single-stage 45 MW, larger electric convective heaters, and decarbonized steam generators for all global voltages by country are now available. Each 10 MW machine is compact today. For example, a 400C 1.2 MW heater is only 24″ long. About twenty-five to fifty 10 MW machines working year-round (~8760 hrs. per year of operation) could be enough to start meaningfully capping emissions at 2022 levels. Contact MHI.

Tips for the best decarbonization equipment. When feasible, choose equipment that offers the best energy efficiency, lowest pressure drops, lowest ancillary costs, highest degree of process control electronics, and highest temperature output (as it leads to rapid productivity and efficiency). Also, choose highly compact units with a low spatial footprint. Choose stainless steel or low-corrosion enclosures and minimize materials that cannot be recycled.
Can one capture CO2 from the air and store it? Perhaps, but what you capture can always be released. Capture costs are high. Please click here to compare the economics of carbon sequestration against simply preventing emissions. Could we avoid making the CO2?

What is Industrial SmartPower™? Decarbonized energy use is a vital aspect of SmartPower. Industrial-scale smart power devices are highly energy-efficient, offer a low footprint/weight, and increase productivity. Using less high-grade energy is always more cost-effective than inefficiently using large amounts of low-grade energy.
MHI products offer energy efficiency with intelligent power. MHI products incorporate clean energy concepts and sustainability demands. MHI’s progress has often been compared to miniaturization in materials and process technologies that parallel rapid advancements in the computer and electronic products industry. MHI’s materials technology developments are expected to improve its industrial thermal products, offering a trusted platform for greater economic and environmental benefits in packaging, tool bits, automotive, textile, and other market sectors. Such benefits reduce weight and material consumption, increase strength, reduce energy consumption, and enhance performance. New materials technologies of interest include novel energy-efficient materials, non-stick metals, water-repellent glass, lightweight alloys and polymers, fluids, and low-friction coatings for biotechnology and nanotechnology applications. These new materials are now fully integrated into MHI industrial thermal products. A key example is using nanostructures at high temperatures for the GAXP®, enabling new nanostructured heating elements. As production demands increase, improving heat transfer rate (speed), energy efficiency, and footprint becomes more critical.

Why Are Energy-Efficient Products Important
Discussions on Conserving the Quality of Energy
Benefits from Electrification of Heating Equipment (Estimates are approximate and not guaranteed).
The electrification of industrial heating has the potential to substantially reduce the total energy consumed in industrial heating processes. Resource utilization of common materials, such as water, is optimized by technology’s energy efficiency. MHI products listed on https://mhi-inc.com/ exhibit exceptional energy efficiency and resource conservation. The technologies included patented technologies that replace conventional process gas heaters and pressure boilers with efficient electric process gas heaters and instant steam generators, operating in the high kilowatt and megawatt power ranges with very high-temperature capabilities. Advances in electrical heating technologies are driven by improved energy conversion efficiency, compactness, and precise control capabilities, thereby ensuring attractive financial payback periods for clean, energy-efficient equipment. Heating and thermal technologies influence productivity substantially. Source.
The industrial sectors include iron, steel, glass, cement, aluminum, polymers, stucco, and mineral processing, encompassing activities from food drying to calcining. While industry-specific needs may influence the types of improvements and new technologies relevant to different sectors, heating remains a universal requirement not confined to specific industry demands. If electric heaters are to be deployed quickly as a substitute for fossil-fired heaters, they must offer attractive payback economics. Such payback can result from improved heater efficiency (typically greater than 95% with MHI resistance electric heating technologies).
In comparison, fuel heaters might achieve only about 50-75% efficiency (due to flue gas, radiation losses, and heat exchanger losses), large-scale induction heaters around 50% (because of coupling losses), and dielectric heaters also around 50% (due to coupling losses). Additionally, MHI heaters can operate at 1200 °C for convection and approximately 1800 °C for radiation. MHI process heaters can function in an oxidizing atmosphere, such as air. Because of these advantages, the payback period for energy-optimized processes typically occurs within a few months, even when higher CAPEX is required for compact equipment made with innovative, U.S.-discovered, enhanced materials. Calculations clearly indicate that enhanced efficiencies can lead to lower OPEX costs and a lower Total Ownership Cost (TCO). Journal Source.
Energy efficiency can prolong a product’s lifespan by optimizing energy consumption throughout its use. A more efficient life cycle is consistently achieved with higher energy efficiency. The enhanced efficiency of high-temperature heaters leads to significant productivity increases and a longer lifespan. Industrial heating is extensively used in the steam generator industry (commonly known as the steam boiler sector). High-temperature steam is utilized for comfort heating, sanitation, controlled textile drying, consumer packaging (shrink wrapping), curing concrete, soy production, antimicrobial purposes, food processing and safety, meat tenderization, milk processing, laundry, skincare, pyrolysis–gasification of municipal waste, and other applications. Industrial systems consume large amounts of steam, much of which cannot be recycled. Traditionally, steam was produced by fossil-fuel-fired pressure boilers, which are often inefficient and yield saturated steam with water droplets, leading to significant energy and water losses. New MHI electrical superheated steam generators produce steam without liquid water, reducing water and energy consumption in many steam processes.
