The UK government's announcement of its "Powering Up Britain" strategy places a huge bet on carbon capture and storage (CCS) technology, despite scientific doubts about its efficacy in enabling an expansion of oil and gas drilling in the North Sea. Grant Shapps MP, the energy and net zero secretary, unveiled the strategy during a visit to a nuclear fusion development facility in Oxford.

According to Shapps, the UK has a geological advantage in storing much of Europe's carbon for the next 250 years in natural undersea caverns beneath the North Sea. The strategy includes support for offshore wind, hydrogen, heat pumps, and electric vehicles. The green finance strategy aims to mobilize private capital investments into green industry, and a consultation on carbon border taxes is intended to penalize imports from overseas with high-carbon impacts.

However, the proposals could face legal challenges. The "Powering Up Britain" strategy is largely a response to a high court ruling last year, which declared that previous government policies were inadequate for meeting legally binding commitments to renewable energy targets. Mike Childs, head of policy at Friends of the Earth, warned that the proposals lacked ambition and would not create enough energy security or reduce bills for consumers.

The government's CCS bet also comes at a time when local concern continues to increase over the climate implications surrounding proposed road construction projects in Norfolk, such as the Norwich Western Link Road. These projects are expected to drive up emissions across the region, making it harder for England's Economic Heartland to reach its target of becoming net-zero by 2040 and reducing car traffic by 5% by 2030. The developments could use up a substantial proportion of local carbon budgets while undermining local actions to tackle climate change.

While CCS technology could potentially play a role in reducing carbon emissions, it is clear that the priority should be given to investing in sustainable and renewable energy sources. The government must also ensure that their policies are in line with its commitment to reach net-zero greenhouse gas emissions by 2050, while also taking into account the concerns of local communities and the environment.
