The next leg of fundraising begins next year, he added. “What I need to do is keep the process going, and as we move forward and achieve milestones, the value of the business goes up and the incremental funding is then cheaper” to obtain. Mowry said “the early money is the most expensive” to raise. General Fusion will need to raise additional sums to complete the work and get the plant into operation, now estimated to cost roughly US$400-million, and to start working with utilities to cultivate early adopters. The process is expected to take another three to four years. General Fusion is set to break ground next summer at UK Atomic Energy Authority’s Culham Centre for Fusion Energy, near Oxford. Now it is in the midst of a project to develop and build a demonstration plant to prove it can do what it promises at scale. Overcoming longstanding skepticism about fusion energy, General Fusion has shown its technology works, Mr. Its key input is water, and its reactor would not be at risk of meltdowns. It injects hydrogen fuel into a molten lead-lithium sphere pressure on the sphere forces fusion reactions within the fuel, releasing heat into the liquid metal that can be converted into electricity. General Fusion has developed a process in which ultraheated hydrogen atoms are fused into helium, as happens in the sun. While the process of nuclear fission generates energy by splitting the nucleus of an atom, the fusion process does the same through combining them.

“Fusion should be the vaccine of climate change,” Mr. The 19-year-old company will need to raise much more before proving its technology, which it has tested successfully, works at scale or that it can function in a commercially viable way – but if it does it could have a profound impact. This will prove fusion not only works as an experiment, but works economically on the scale of a power plant.That brings the total raised to date by General Fusion to well over US$300-million, including support from governments in Canada, the United States and Britain, CEO Christofer Mowry said. The challenge now is to develop the technology and engineering of tokamaks to capture fusion neutrons and produce electricity. ITER will demonstrate the physics of controlling a power plant-scale fusion plasma. The JET experiments are vital for the next large international experiment, ITER, and will also influence the design work of demonstration fusion powerplants, DEMO and STEP.ĬCFE is part of a worldwide research programme to show that fusion is viable. However, research into reducing these requirements – notably through the use of superconducting magnets – is underway. Today’s tokamaks have high auxiliary power requirements to run the heating systems and energise the magnetic coils. During this experiment, JET averaged a fusion power of around 11 megawatts. JET has produced a record-breaking 59 megajoules of sustained fusion energy over a five second period (the duration of the fusion experiment) using deuterium and tritium – the same fuel mix that will be used in future powerplants.

Researchers have overcome many of the scientific hurdles in fusion – developing a good understanding of how to control and confine the hot plasma of fuels. CCFE’s goal is to develop fusion reactors using the tokamak concept. The most advanced device for this is the ‘tokamak’, a Russian word for a ring-shaped magnetic chamber. One way to control the intensely hot plasma is to use powerful magnets. A plasma with millions of these reactions every second can provide a huge amount of energy from very small amounts of fuel. The gas becomes a plasma and the nuclei combine to form a helium nucleus and a neutron, with a tiny fraction of the mass converted into ‘fusion’ energy.

To produce energy from fusion here on Earth, a combination of hydrogen gases – deuterium and tritium – are heated to very high temperatures (over 100 million degrees Celsius). This is the opposite of nuclear fission – the reaction that is used in nuclear power stations today – in which energy is released when a nucleus splits apart to form smaller nuclei. When light nuclei fuse to form a heavier nucleus, they release bursts of energy. Fusion is the process that takes place in the heart of stars and provides the power that drives the universe.
