Light blue vans12/29/2023 ![]() ![]() Hydrogen produced from electrolysis could also be used as an indirect form of electric heating however, since the cost is expected to stay higher than direct electrification, it is most suited for higher temperatures for which direct electrification is not available. Many other forms of electric heating exist, such as electric boilers and induction heaters. The NZE Scenario sees them supplying about 7% of light-industry heat by 2030. Heat pump units – which commonly run on electricity – able to provide heat above 100 ☌ are now entering the market, with some reaching 200 ☌. Since more than 90% of total heat demand is low or medium temperature (below 400 ☌), there is wide scope for electrification. Unlike in many other industries, most of the technologies needed for net zero emissions in light industry are already on the market. The result is that fossil fuel use declines to less than a quarter of total energy in 2030. ![]() In the NZE Scenario, the share of electricity increases at an even faster rate – about 3% per year – to make up around 55% of energy consumption by 2030, alongside continued growth in bioenergy use, and a very large proportional (but relatively small absolute) increase in the use of emerging near zero technologies like solar thermal, geothermal energy and hydrogen. More than 70% of the additional energy used in 2021 compared to the previous year was electricity, showing that electrification continued even in a year where emissions increased. The main contributor to this decline is electricity, which grew as a proportion of total final energy by about 2% per year between 20. ![]() Their share is on the decline – in 2005 they accounted for about 52% of final energy use. The majority of the fossil fuels used in light industry are for generating process heat, while electricity is used primarily to power motor-driven systems as well for process heat, cooling and lighting.įossil fuels made up 38% of the final energy used in light industry in 2022. ![]() Overall, the largest consumer of energy in light industry is process heat for applications such as drying, metal melting and food preparation. Efforts must accelerate to get on track with the Net Zero Emissions by 2050 (NZE) Scenario, under which emissions decline by 6% per year to 2030, compared to 1.6% on average over the past decade.Įnergy is used for a wide array of purposes in light industry, and its application varies widely according to the sector in question. However, these changes are not yet occurring fast enough. Conversely, these sectors are spread over many more manufacturing sites and companies than heavy industry, adding to the complexity of deploying clean technologies at scale.Ĭonsiderable progress has been made in lowering emissions over the past decade, including deployment of low-emission heating technologies, such as industrial heat pumps, and energy efficiency measures. Key components of light industry include the production of food (30% of light-industry emissions), machinery (16%), textiles (7%), vehicles (6%) and timber (3%), as well as construction (21%) and mining (18%).Įmissions from light industry are generally easier to abate from a technological point of view than heavier industry due to lower temperature requirements. This wide-ranging sector accounts for 8% of all industrial emissions. Light industry describes a range of sectors with lower absolute energy use than heavy industry such as steel and cement. ![]()
