Investment in nuclear fusion has reached $2.8bn in the last 12 months, surpassing the total investment of $1.9bn over the past decade. Nuclear fusion is a clean energy solution that produces energy by fusing together atomic nuclei, and it is considered safer than traditional fission nuclear power. The UK plans to host the first prototype fusion power plant, with five locations in the running. Breakthroughs in fusion research have been made, including a record-breaking 59 megajoules of fusion achieved in 2021.
