Why Allocating £20 Billion to Nuclear Energy Instead of Carbon Capture Makes Sense

Updated: Mar 28, 2023


As the UK government recently announced £20 billion in funding for carbon capture, utilization, and storage (CCUS) technology, questions have emerged about the efficacy and sustainability of this approach. While CCUS has its merits, the allocation of these funds towards the development of nuclear energy might yield greater environmental and economic benefits in the long run.


Carbon capture technology, though promising, has several disadvantages that might hamper its role in addressing the climate crisis. The high costs associated with developing, installing, and maintaining CCUS infrastructure pose a significant barrier to widespread adoption. Moreover, the energy penalty incurred by carbon capture processes reduces the overall efficiency of power plants and industrial facilities, potentially increasing CO2 emissions or promoting the destruction of local habitats through increased consumption of natural resources such as water.


Furthermore, the slow deployment of CCUS technology and its limited applicability to large, stationary sources of CO2 emissions raise concerns about its effectiveness in reducing global emissions. Allocating £20 billion to this technology, while it may be beneficial in certain hard-to-decarbonize sectors, may not be the most effective use of resources in the fight against climate change.


In contrast, investing in nuclear energy, which has received considerable support in the new UK budget, could offer more substantial environmental and economic benefits. Nuclear power is a reliable, low-carbon energy source that can provide baseload electricity without emitting greenhouse gases during operation. With advancements in small modular reactors (SMRs) and other innovative nuclear technologies, the sector is poised for significant growth.


One of the critical advantages of investing in nuclear energy is the potential for job creation in a high-skilled sector. The development, construction, and operation of nuclear power plants require expertise in engineering, science, and technology, which can create sustainable, high-paying jobs. The government's recent announcement of the 'Great British Nuclear' development body is a step in the right direction, but additional investment in the sector could further strengthen the UK's position as a leader in nuclear energy.


Another compelling argument for investing in nuclear energy is its potential to complement renewable energy sources, such as wind and solar. Nuclear power can provide stable, continuous electricity supply when renewable sources are intermittent or unavailable, ensuring a reliable and low-carbon energy mix. Moreover, classifying nuclear power as 'environmentally sustainable' in the government's green taxonomy, as proposed in the budget, can unlock additional private investment and incentives for the sector.


In conclusion, while carbon capture technology has a role to play in addressing climate change, the £20 billion in funding might be better allocated towards nuclear energy development. Doing so could lead to greater environmental and economic benefits, including the creation of a highly skilled workforce and a more reliable, low-carbon energy system. The UK should seize this opportunity to invest in the future of nuclear energy and solidify its position as a global leader in the fight against climate change.
