The most promising companies in the clean energy industry
Commonwealth Fusion Systems uses a tokamak for nuclear fusion – a radio wave device to heat hydrogen isotopes to over 100 million°C. A magnetic field compresses the resulting plasma until atoms come together, releasing a burst of electrons and neutrons. What sets Commonwealth Fusion Systems apart is the compact size of its tokamak. The prototype SPARC reactor will be 40 times smaller than the ITER international fusion reactor being built in France and could be launched five years earlier. SPARC should generate the first plasma by the end of 2025, and its successor, the ARC reactor, will be able to send energy to the power grid in the early 2030s.
The Danish company Ørsted has built the most offshore wind farms in the world. By 2030, it hopes to achieve 30 GW of power from offshore wind energy, among others, thanks to a network of projects implemented in Europe (Great Britain, Poland, Denmark, Germany), the USA and the Asia-Pacific region (Taiwan). Ørsted has also started preparing to construct innovative floating offshore wind turbines.
Fervo Energy is based on an emission-free energy source: geothermal technology. It uses the hydraulic fracturing method, thanks to which the American company creates and enlarges cracks under the earth’s surface to allow water to circulate more easily. This is an improved type of geothermal power plant that works by circulating water through hot rock deep underground and then converting this heat energy into electricity at the surface.
