Solar farms are blooming in fields across the globe and producing a new crop: solar energy. Photovoltaic (PV) systems made up of solar panels, are fast becoming the most recognisable of renewable energy technologies.
Think of the largest cruise ship. Then imagine how much it weighs – just over 100,000 tonnes, in fact. Now think about 500 of those ships, and what they weigh. That is the staggering amount of new electronic waste that we generate every year.
As delegates to the UN COP26 Climate Change conference in Glasgow grapple with the climate crisis, clean energy solutions will be in focus. Although clean energy technologies rely on metals and minerals that are unavoidably energy intensive to produce, the IEA says that the climate advantages of these technologies remain clear.
Even small quantities of nickel in an application can make a big difference to successful deployment.
Nickel-based alloys and nickel-containing stainless are playing key roles in an emerging source of renewable energy known as thermal solar plants or concentrated solar power (CSP). Their use has enabled the industry to overcome challenges in heat transfer and thermal storage technology.
Geothermal energy for electric power production has a low profile yet is significant in the current and potential energy mix for a number of countries. It has also been described as the most reliable of the renewable energy sources, above weather-dependent wind, solar and hydropower.
The many new and innovative applications of hydrogen as fuel show great promise for a greener future.
