The world is currently witnessing a transition from fossil fuels to renewable energy sources. While this shift is happening at a rapid pace, it is not fast enough to meet the Paris goals. The energy mix is expected to move from 80% fossil-based to 50% non-fossil-based within a generation. This transition is being driven by advancements in wind and solar power, with electricity production set to more than double by 2050. Despite these positive developments, challenges remain, particularly in industries that contribute significantly to GHG emissions and are difficult to transition away from fossil fuels. However, innovative solutions, such as green hydrogen, show promising potential in decarbonising carbon-intensive industries.

The transition to green energy is accelerating in Europe, but slowing in India
However, in India, the transition to green energy is forecast to slow down, with more coal in the energy mix. This is due to changes in the geopolitical landscape, which have made governments more willing to pay a premium for locally sourced energy.
Despite these regional differences, the long-term trend for the energy transition is clear: the world energy system will move from an energy mix that is currently 80% fossil-based to one that is about 50% non-fossil based by mid-century. This shift is expected to happen within a single generation, which is fast but not fast enough to meet the Paris goals.
To accelerate the transition to green energy and meet the Paris goals, it is crucial to address the incentives and disincentives surrounding the deployment of renewables and the reduction of emissions from fossil fuels. While technology is not the main challenge, there is a need for innovative and stable energy storage solutions to improve the capacity of battery storage and enable the long-term storage and long-distance transport of non-fossil energy.

The energy mix will be 50% non-fossil based in a single generation
The world energy system is currently 80% fossil-based, but it is predicted that this will shift to 50% non-fossil based in a single generation. This is a fast transition, but it is not fast enough to meet the Paris goals. The transition to renewable energy sources is being driven by energy security and governments are willing to pay a premium for locally sourced energy. For example, in Europe, the transition is accelerating with the alignment of climate, industrial and energy security objectives. Most energy additions are now wind and solar, which are predicted to grow 9-fold and 13-fold respectively between 2022 and 2050. Electricity production is also expected to more than double between now and 2050, bringing efficiencies to the energy system.
Innovative and stable energy storage solutions are critical to enabling improvements in the capacity of battery storage and the long-term storage and long-distance transport of non-fossil energy. For example, 'Power-to-X' involves making hydrogen from water using electricity, which, when renewable electricity is used, produces renewable or 'green' hydrogen with a very low carbon footprint. This green hydrogen has the potential to transform carbon-intensive industries such as steelmaking and cement, with exciting potential applications for aviation.
Despite these advancements, there are short-term setbacks due to increasing interest rates, supply chain challenges, and energy trade shifts due to the war in Ukraine. Additionally, some regions, such as the Indian Subcontinent, are forecast to transition slower with more coal in the energy mix.

Solar and wind power are growing
The current energy mix is 80% fossil fuels and 20% non-fossil fuels, but this is expected to change to a 48/52 split by mid-century. This shift is being driven by a number of factors, including energy security and geopolitical landscape changes. Governments are increasingly willing to pay a premium for locally sourced energy, which has impacted the transition to renewables. For example, the Indian Subcontinent is now forecast to transition more slowly with more coal in the energy mix, while Europe is accelerating its transition with the alignment of climate, industrial and energy security objectives.
The growth of solar and wind power is also being driven by increasing investment in these technologies. In recent years, there has been a significant increase in investment in wind and solar power generation, which has resulted in advances in these technologies and an increase in their efficiency. This investment is expected to continue, with most new energy additions being wind and solar.
Despite the growth of solar and wind power, there are still challenges to transitioning away from fossil fuels. Technology is not the main challenge, but rather the incentives to drive the fast deployment of renewables and storage, and disincentives to drive down emissions from fossil fuels, are lacking. However, the long-term trend for the energy transition is clear: the world energy system will move from an energy mix that is 80% fossil-based to one that is about 50% non-fossil-based in the space of a single generation. This is a fast transition, but it may not be fast enough to meet the Paris goals.

Energy storage solutions are improving
One key area of improvement in energy storage solutions is battery storage capacity. Developments in battery technology are enabling the long-term storage and long-distance transport of non-fossil energy, such as "green" hydrogen. Green hydrogen is produced by using renewable electricity to split water into hydrogen and oxygen, resulting in a very low carbon footprint. This technology has the potential to transform carbon-intensive industries such as steelmaking and cement production, as well as aviation.
Another area of focus for energy storage solutions is the integration of renewable energy sources into the grid. As renewable energy sources become more prevalent, it is important to ensure that the grid can handle the intermittent nature of these sources. Energy storage solutions, such as pumped hydro and compressed air energy storage, can help to balance the grid and ensure a stable supply of electricity.
Additionally, energy storage solutions are becoming more cost-effective, which is driving their adoption. The cost of lithium-ion batteries, for example, has decreased significantly in recent years, making them a more viable option for grid-scale energy storage. This trend is expected to continue, with further cost reductions anticipated in the coming years.
Overall, the improvements in energy storage solutions are playing a critical role in the transition to green energy. By enabling the long-term storage and transport of non-fossil energy, as well as providing grid stability, these solutions are helping to accelerate the shift away from fossil fuels. As technology continues to advance and costs decrease, it is expected that energy storage solutions will become even more widespread and effective, further contributing to the goal of a more sustainable energy future.

Industries that contribute to GHG emissions are difficult to transition away from fossil fuels
Despite these advancements, the transition to renewable energy sources is not happening fast enough to meet the Paris goals. The world energy system will move from an energy mix that is 80% fossil-based to one that is about 50% non-fossil-based in the space of a single generation. This is a significant shift, but it needs to happen faster to address the climate crisis effectively.
One of the challenges in transitioning away from fossil fuels lies in the lack of incentives to drive the fast deployment of renewables and storage, as well as the lack of disincentives to reduce emissions from fossil fuels. Additionally, some industries, such as steelmaking, cement, and aviation, are carbon-intensive and require more time and technological advancements to transition fully to renewable energy sources.
To accelerate the transition, innovative energy storage solutions are being developed to improve the capacity of battery storage and enable the long-term storage and long-distance transport of non-fossil energy. One example is "Power-to-X", which involves making hydrogen from water using electricity to produce renewable or "green" hydrogen with a low carbon footprint. This green hydrogen, along with carbon dioxide from captured emission sources, has the potential to transform carbon-intensive industries and reduce their reliance on fossil fuels.
