Drivers: Escalating demand for dependable and uninterrupted power

For any nation to experience growth, electricity is a vital resource. According to the EIA's International Energy Outlook 2019, global energy demand is anticipated to rise by 2.11% annually until 2040. Non-OECD nations like China and India are estimated to account for a key share of the market growth. However, due to COVID-19 and the consequent economic crisis, the short-term electricity demand in 2020 declined by 5%. Demand is projected to decline by 2% in the case of a fast recovery. Developing regions experience power outages and blackouts, while developed regions have more voltage fluctuations and brownouts.

Restraints: The availability of alternative sources of energy is projected to impede the market growth

In many industrialized nations, energy sources like SOFC cells, solar PVs, renewable energy, batteries, and fuel cells serve as substitute sources of power generation and storage. For instance, in the US, the need for effective power generation has been growing as more businesses look for ways to lower their electricity and heating bills.

Energy efficiency for solid oxide fuel cells is about 60% as compared to other technologies such as reciprocating engines whose efficiency is less than 35%. Additionally, the cost of energy production per unit has decreased due to the expansion of renewable energy sources like solar and wind. Diesel power generation costs are two to three times higher than those associated with renewable energy sources.

To comply with environmental requirements and limit emissions, strict governmental standards have been implemented for diesel fuel globally. The US EPA specified that the ultra-low Sulphur diesel standard to be used for non-road diesel engines. The primary difficulty facing generator producers is lowering pollution levels while maintaining performance standards. Numerous manufacturers introduced new goods in 2018–20 that meet these exacting requirements.

Opportunities: Increasing hybrid electricity generation in remote and rural areas

Hybrid power generation can supply the needed electricity to off-the-grid or remote places including telecom towers, isolated industrial facilities, tiny communities, islands, and more. Most of the off-grid locations are in developing nations like Asia Pacific and Africa, where electrification is not universal. According to World Energy Outlook, in Sub-Saharan Africa, the electrification rate is 35%, but only 19% of the rural areas are electrified, leaving 550 million people without access to electricity.

Due to the absence of grid networks in countries in Asia Pacific, nearly 600 million people stay without access to electricity. Grid network construction in these areas is expensive and necessary for achieving 100% electrification. Hybrid power solutions using diesel generators and renewable energy sources are used to meet the energy needs of such remote installations.

The standby segment is estimated to grow at a rapid pace during the projected period

On the basis of operations, the market is fragmented into peak shaving, prime/continuous, and standby. The standby segment is estimated to grow at a rapid pace during the projected period. End users rely on standby diesel engines to provide emergency power. The user can depend on the diesel-engine powered gensets to temporarily meet the demand in the event that the grid's power supply is lost.

Growth of the segment is attributed to the absence of widely applicable, commercially viable alternatives for backup power sources, low initial cost of diesel engine-powered generators, and quick start capability. The market for diesel engines is projected to be fueled by rising industrialization in Asia-Pacific and rising data center investments in Europe and North America.

The commercial segment to account for a key market share in the coming years

In terms of end-users, the market is divided into residential, commercial, and industrial. The commercial segment is expected to account for a key market share in the coming years owing to increasing investments in the commercial sector, especially in datacenters and hospitals. Over USD 70 billion was spent on capital projects by companies such as Facebook, Apple, Alphabet, Amazon, and Microsoft. For datacenters to remain operational despite interruptions in the main power grid supply, emergency backup power is necessary. These advancements are anticipated to fuel the commercial segment.

The industrial segment is anticipated to dominate the market during the forecast period. The industrial sector often uses more energy for its commercial operations. The diesel engine improves the quality of the power supply and provides better reliability. Diesel engine usage is rising as a result of robust industrial expansion and the development of commercial infrastructure. Major industries that heavily rely on the power produced by diesel engines include data centers, telecommunication, oil & gas, healthcare, manufacturing, and construction sector.

Power outages in the manufacturing sector resulting in low volume production and the sale of substandard quality products. In industrial sectors, blackouts usually impact all processes. Therefore, the industrial units rely on diesel engines, which function as the best power source, to prevent such failures. The industrial segment is therefore anticipated to dominate the diesel engine market during the forecast period based on the aforementioned aspects.
