As the world progresses and evolves, the demand for energy is forecasted to soar in the coming decades. The International Energy Agency predicts that global energy consumption will likely increase by 25% by 2050. This presents a unique opportunity for us to embrace sustainable and renewable energy sources such as solar, wind, hydropower, and natural gas, among other technologies and solutions.
By diverting our attention towards these forms of energy, we will not only be able to meet the growing demand but also reduce our dependence on fossil fuels and minimise our environmental impact. Therefore, we must take this opportunity to focus on sustainable energy solutions to secure a brighter future for our planet and its inhabitants. Currently, the industry is exploring different fuels and power sources – hardware that could achieve these goals, mainly utilising alternative fuel and electrification.
Fuel flexibility with decarbonisation
We currently get most of our power from diesel, which will gradually diminish over the next five to 20 years. We also see an uptick in the use of natural gas. Furthermore, alternative technology power sources are anticipated to increase steadily in the next decade or two, while the electrification of the oil field continues to grow with the use of fuel cells, electric motors, and other technologies, such as batteries.
When analysing alternative fuels within the upstream sector, they can be broken down into three categories: established, emerging, and future prospects. Established alternatives include diesel, natural gas, and a combination of both. Emerging options include hydrogen, fuel cells, dual fuel, batteries, and hybrid technologies. Meanwhile, future prospects include hydro-treated vegetable oil (HVO)/green diesel, ammonia, and a blend of natural gas and hydrogen; diesel and hydrogen, as well as others, which are considered viable options for reducing dependency on traditional fossil fuels and increasing sustainability within the industry.
The need for sustainable and low-carbon energy sources and technologies have never been more pressing. The shift towards green energy and alternative low-carbon fuels is necessary for addressing the pressing issue of climate change and protecting our planet for future generations.
However, it is essential to note that implementing alternative fuels may not be a straightforward process and will require significant investments in new technology and infrastructure, as well as changes in consumer behaviour and government policies. Additionally, alternative fuel costs may be higher than fossil fuels, which could be a barrier to widespread adoption.
Besides low carbon fuel alternatives, which have been discussed, new power solutions and technologies are being developed by organisations such as Cummins to reduce GHGs from internal combustion engines and increase the adoption of fuel cells, battery electric and hybrids.
So, how is Cummins innovating its power solutions?
At a recent conference, Cummins’ operations director, Ian Norton, spoke about how the company is looking at innovating its products and power sources by utilising alternative fuels and electrification. Under electrification, Cummins currently offers two types of stationary power technology platforms – solid oxide fuel cells (SOFC) and proton exchange membrane fuel cells (PEMFC).

SOFCs and PEMFCs are fuel cells that convert chemical energy into electrical energy. However, there are some key differences between the two. SOFCs use a solid oxide electrolyte, typically made of ceramic materials, as opposed to a polymer electrolyte membrane (PEM) used in PEMFCs.
This means that SOFCs can operate at higher temperatures and are more tolerant of impurities in the fuel. Due to their high operating temperatures, SOFCs can also use a variety of fuels, including natural gas, propane, and even diesel. They are also more durable and have a longer lifespan compared to PEMFCs.
PEMFCs, on the other hand, operate at lower temperatures and require a purer fuel source, such as hydrogen. They are also more efficient at converting the chemical energy in the fuel to electrical energy. In addition, they are relatively more compact and lightweight, which makes them more suitable for portable and mobile applications, such as powering vehicles.
Expanding green hydrogen globally
Cummins is also working towards expanding its global clean energy footprint by expanding its electrolyser manufacturing capacity globally.
In addition to currently operating plants in Canada and Belgium, Cummins has announced new electrolyzer manufacturing plants in China, US and Spain. The investment in expanding gigawatt electrolyzer manufacturing facilities is a demonstration of reaffirming its commitment to expanding the green hydrogen economy in Europe and globally.
The need for sustainable and low-carbon energy sources and technologies have never been more pressing. The shift towards green energy and alternative low-carbon fuels is necessary for addressing the pressing issue of climate change and protecting our planet for future generations.
In conclusion, solutions such as implementing technologies like SOFCs and PEMFCs, decarbonising and improving the grid’s resiliency, and developing and maturing a green hydrogen economy represent a significant step forward in developing alternative energy sources.
With continued investment and dedication, we can build a cleaner, more sustainable energy system that benefits us all. However, it is essential to remember that this is a collective effort, and we all have a role to play in this transition towards a greener future.
