What You'll Learn
Steel, electricity, chemicals, and petroleum were needed to make businesses more productive
The Industrial Revolution, particularly the second phase, gave rise to steel, electricity, chemicals, and petroleum. These four factors were needed to make businesses more productive.
Steel, for instance, was used in construction, from bridges to buildings, and in the emerging railways, replacing iron. It enabled the manufacture of large, powerful turbines and generators, harnessing the power of water and steam to drive industrialization and bring about the age of electric power. Steel was also used in the first steel liners, like Cunard's SS Servia, which featured electric lighting. Furthermore, steel was used in the production of automobiles, home appliances, and shipping containers, playing a vital role in transportation and trade.
Electricity was another key factor in improving productivity. It enabled the inexpensive production of electro-chemicals such as aluminium, chlorine, sodium hydroxide, and magnesium. Electricity also replaced kerosene and gas lighting, providing brighter and more efficient illumination for streets in the 1890s and households in the 1920s.
Chemicals, particularly synthetic dyes, played a significant role in the Second Industrial Revolution. English chemist William Henry Perkin discovered synthetic dyes in 1856, and by 1900, the German chemical industry dominated the world market for these products.
Lastly, petroleum, which emerged alongside the refining industry in 1848, was crucial in the development of the oil and gas industry. The mass production of automobiles led to gasoline shortages during World War I, but these were alleviated by the Burton process for thermal cracking, which doubled gasoline yields.

Steel production's environmental impact
Steel is used in everything from cars to buildings to wind turbines. The steel industry is the largest consumer of energy in the world among industrial sectors. Steel production is an energy-intensive process that has a significant environmental impact. It is among the most carbon-intensive manufacturing processes, producing about 7% of carbon dioxide emissions globally. For every ton of steel produced, up to two tons of carbon dioxide are emitted, adding up to nearly 10% of such emissions worldwide.
The industrial processes involved in steel production primarily release greenhouse gases. Carbon dioxide is the main gas released into the atmosphere during steel production. Other gases, such as methane, are also produced, which are even more harmful due to their atmospheric impact and contribution to global warming. The high temperatures required by smelting furnaces in the steel industry are achieved by burning fossil fuels such as coal and natural gas.
The presence of particulates in the air from steel production contributes to smog, which is a mixture of air pollutants. These pollutants can reach areas far from the steel production sites, as they are easily carried by wind and atmospheric circulation. Exposure to these pollutants has serious consequences for human health and the environment, with health conditions such as asthma, chronic bronchitis, and obstructive pulmonary diseases being linked to them.
SO2 and NOx emissions from steel production lead to acid rain, which affects soil composition, water bodies, and vegetation. Additionally, the fiery molten metals used in steelmaking emit electromagnetic, infrared, and ultraviolet radiation, which can be hazardous to workers' health and the surrounding environment.
There are ongoing efforts to reduce the environmental impact of steel production. Boston Metal, for example, has developed technology to electrify steelmaking through molten oxide electrolysis (MOE). This process relies on electricity instead of carbon to remove oxygen, resulting in emissions-free steel. While transitioning to larger reactors has presented challenges, the potential for scaling up clean production processes and accessing renewable electricity sources holds promise for mitigating the environmental impact of steel manufacturing.

Electrification and electro-chemicals
The Second Industrial Revolution, which began in the 1840s, saw the emergence of new technologies and innovations that transformed society and the global economy. Electrification played a pivotal role in this era, enabling the inexpensive production of electro-chemicals such as aluminium, chlorine, sodium hydroxide, and magnesium. The availability of cheap electricity facilitated the development of new industrial processes, particularly in the steel industry.
Steel became one of the key drivers of the Second Industrial Revolution, replacing iron in railways, construction, and shipbuilding. The Bessemer process, for instance, made steel widely available at competitive prices, leading to its widespread adoption in buildings, bridges, and ships. This revolutionised architecture, giving rise to the first skyscrapers and larger, taller buildings. Steel also enabled the manufacture of powerful turbines and generators, harnessing water and steam power to drive further industrialisation and the age of electric power.
The steel industry itself underwent significant advancements during this period, with the introduction of basic oxygen steelmaking and electric arc furnaces. These innovations improved production processes, making them faster and more energy-efficient, and even allowed for the reuse of scrap metal. However, the steel industry has long relied on fossil fuels and is responsible for significant carbon dioxide emissions.
In recent years, there has been a growing focus on decarbonising the steel industry and harnessing the power of electrification to develop more sustainable steelmaking processes. Boston Metal, for instance, has developed a process called molten oxide electrolysis (MOE) that uses electricity instead of carbon to remove oxygen from iron ore, resulting in emissions-free steel. While scaling up such technologies remains a challenge, they hold the key to reducing the environmental impact of the steel industry and transitioning to a greener future.
In conclusion, electrification and electro-chemicals played a pivotal role in the Second Industrial Revolution, with electricity enabling the production of chemicals and transforming the steel industry. Today, electrification is once again at the forefront of efforts to create a more sustainable steelmaking process and address the climate impact of this vital industry.

Germany's chemical industry
The German chemical industry has a long history of success. Before World War II, it dominated the European market, and even after the war, when organic chemical production was halted, the industry rebounded quickly. By the mid-1950s, West Germany was producing around a third of the output of organic chemicals in the UK. The country's largest chemical company, BASF, employed around 110,000 workers and generated a turnover of 59 billion euros in 2020.
However, in recent years, the industry has faced several challenges. The energy crisis, high inflation, and rising interest rates have pushed Germany and other European economies into recession, resulting in a decline in industry production. High energy prices, particularly natural gas prices, have significantly impacted the chemical industry, which consumes around 8% of Germany's energy, including 15% of its natural gas and 10% of its electricity.
Structural issues, such as high taxes, levies, and bureaucracy, have also slowed down the industry. Germany's chemical industry is struggling to compete with larger enterprises in other countries, which can more easily relocate production to China or the US. Investments into Germany have decreased by around 90% since 2018, and the country is facing shrinking domestic demand.
Despite these challenges, the German chemical industry is committed to sustainability and innovation. Almost 80% of German chemical and pharmaceutical companies have research activities, with R&D spending reaching approximately €14 billion in 2023. The industry is exploring new technologies, such as nano- and biotechnology, the hydrogen economy, and digitalisation, to achieve sustainability goals. Additionally, the German government's "High Tech-Strategy" is expected to drive growth in the chemical industry through process and organisational innovations.
