The European science ministers will meet in Paris in November. One of the items on their list to consider is a proposal for testing the feasibility of building commercial power stations in space. The sunlight would be converted to power and sent down to Earth to be fed into the power grid. If the idea can contribute to Europe's future energy security, it will be determined by the proposed project.
It will be similar to coming home to the space industry, which has always been at the forefront of solar power development. The battery-powered Sputnik 1 was launched by the Russians a year later. This was the first satellite to use solar energy. Since that time, solar panels have become the primary source of power for satellites. Only 9% of the captured sunlight was converted into electricity. The cost of fabrication has fallen while the efficiency has increased. The formula is a winner.
According to Jochen Latz, a partner at McKinsey & Company, the cost of solar has been decreasing rapidly over the past two decades. Solar power is the cheapest way to produce electricity in the Middle East and Australia. According to Latz, this will happen in the mid-latitude countries as well. If the countries achieve their targets, more than 40% of the energy in the EU will come from solar power. It would make solar power the largest contributor to the EU.
There are many problems that need to be solved if we are to fully use solar panels. We don't know what to do at night. Ned Ekins-Daukes, associate professor at the school of photovoltaic and renewable energy engineering at the University of New South Wales, Australia, and his team of researchers demonstrated a solar cell that could generate electricity from the emission of IR rather than the absorption of sunlight. The Earth is able to store energy from the sun in the form of heat and then send it back into space.
The prototype device can only produce a small amount of power, but Ekins-Daukes sees a lot of potential. He says that the team is aiming for a finished product that is ten times more powerful. It is possible that a rooftop installation of such devices, probably fabricated in some way as an additional layer to conventional solar panels, could capture enough energy to power the house overnight. It becomes significant when you add that to the country's population.
Some days will be cloudy with the use of solar power. Storage capacity is not good enough to store excess electricity generated on sunny days. The EU will need 200 gigawatts of battery storage by 2030, but as of 2021, there was only 2.4GW of storage in place.
McClean supports a scheme called vehicle-to-grid, which uses the battery in an electric vehicle to store excess energy generated by a home's rooftop solar panels and then transfer it back into the house when needed in the evening. McClean says that if V2G is widely adopted, the expected storage capacity of all the EV will vastly exceed any expected storage requirements. Participants in a recent V2G trial saved money and cut their carbon footprint by using an "intelligent" charging system that topped up the batteries when renewable energy was generating electricity.
Solar power can be used to make sustainable vehicle fuels, instead of generating electricity. A group of people, including a professor at Cambridge University, have created an artificial leaf that is inspired by photosynthesis. Plants take in sunlight, water and carbon dioxide and convert them into oxygen and sugar. Synthetic gas is produced in the artificial leaves. A mixture of hydrogen and carbon monoxide can be used to make a variety of fuels. It is1-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-6556 is1-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-6556
We wanted to use CO2 from the atmosphere or other industrial processes to create green fuel. We have a circular carbon economy because we don't release more CO 2 into the atmosphere. They would piggyback off carbon-capture plants, which are currently being deployed to harness CO 2 from industrial processes.
The artificial leaf was made with glass and metal on a bench top. The team announced the results of a leaf-like structure that they floated on the river cam. The leaf was sealed in a transparent plastic bag and left on the river for a number of days. After opening the bag, the team tested what gases had been produced.
The leaves are made of materials. The mineral of calcium titanium oxide, also known as calcium titanate, was discovered in the Ural mountains of Russia by German mineralogist Gustav Rose in the 19th century. Some solar cells have shown that they can function as solar cells.
The materials are new and exciting. They can be more efficient than the conventional solar panels that use Silicon. The solar panels of the future could be made with perovskites as they can be made more easily and in thinner, flexible layers. The reactions that were used in the artificial leaves study were able to take place because of the higher currents and voltages that these materials produce.
There is a problem with generating solar power from the surface of the Earth. Our atmosphere scatters about half of the sun's light. The blue sky is created by the scattering of light around it. The sun's light is not reflected in the atmosphere. The engineers at the beginning of the space race found that putting a solar panel in space will generate more power than the panel on Earth. Engineers and visionaries have been dreaming of putting satellites into space for a long time.
Lowering the cost of sending equipment into orbit is the holy grail for space solar power
The principle is easy to understand. A fleet of spaceships with giant solar panels collect the sun's rays and convert them into power. How do you transmit energy? We've been doing it for a long time. Since the 1960s, every telecommunications satellite has used a solar panel to generate electricity and send it to Earth. The microwaves are converted into electrical energy on the ground. The scale of space-based solar power isn't the same as the physics involved in that whole chain.
The idea of space solar power has been studied for a long time. The cost of launching large satellites is prohibitive. Things aren't the same now.
A miracle takes place in 2015. John Mankins is a former physicist who is now president of Artemis Innovation Management Solutions. Mankins has worked on many solar-power satellites feasibility studies over the years. The cost of sending equipment into space is falling because of the new rocket. The price of launching every kilogram into space is expected to come down to $300 a kilogram. The holy grail for space solar power is that one. He says it will happen in the next five or seven years.
Some people are also optimistic. According to a report published in September 2021, space solar power is technically feasible, affordable, and could both bring substantial economic benefits for the UK. Esa's studies on space-based solar energy arrived at the same conclusion for the whole of Europe. The agency will request in November that its member states fund a three-year feasibility study into solar-power satellites to examine in detail whether such a system might become commercially viable. Vijendran says that solaris is a bridge to check that this is doable and that it would help before asking for billions of euros.
There is no doubt that solar power is going to dominate the energy landscape of the future. That could lead to better energy security as well as a reduction in carbon output.
