2022 is set to be a record year in terms of the scale at which the switchover from fossil fuels to renewable sources will take place. It's also a year in which we will see new and exotic sources of energy emerge from laboratory and pilot projects. Artificial intelligence (AI) is having transformative effects across energy and utilities. It is used to forecast demand and manage the distribution of resources, to ensure that power is available at the time and place it's needed with a minimum of waste. Hydrogen is the most abundant material in the universe and produces close to zero greenhouse gas emissions when burnt. Green [hydrogen] is created by a process involving electrolysis and water, and generating the required electricity from renewable sources like wind or solar power effectively makes the process carbon-free. This year, a number of major European energy companies, including Shell and RWE, committed to creating the first major green hydrogen pipeline from offshore wind plants in the North Sea throughout Europe. In solar, companies including Dutch startup Lusoco are finding new ways to engineer photovoltaic panels using different reflecting and refracting materials " including fluorescent ink - to concentrate light onto the solar cells, leading to more efficient harvesting of energy. This results in panels that are lighter as well as cheaper, and less energy-intensive to produce and install. New materials are also being developed that convert energy more effectively.
