Not all rooftops can bear the weight of glass PV modules. Some others have curves and shapes ill-suited to uniform, bulky panels. Flexible modules have long been advanced as the solution here, however the keys to unlocking this potential have proven elusive.
German energy company Steag is helping Thyssenkrupp decarbonise its steel production site in Duisburg-Walsum. Green hydrogen generation is expected to be powered by a mix of wind and solar power.
Scientists in the Netherlands have identified five different profiles of homeowners that have installed or could install rooftop PV systems. According to their findings, substantial differences characterise the five segmentation groups. The research is intended to help policymakers and solar companies to better promote PV technology among potential new adopters.
Dutch scientist Bonna Newmann spoke with pv magazine about the present and future of vehicle-integrated PV from a technological and economic perspective. Solar panels installed on cars could have a payback time of only three or four years and ensure 10,000 km of pure PV-generated road travel per year, she said. Furthermore, if you live in a sunny place, you can drive an electric car with solar panels for weeks during summertime, without the need for recharging, she pointed out.
Scientists in Germany have estimated that roof and facade PV systems can cover almost 40% of the total requirements of a standard office building, assuming that no battery storage is installed.
Large swaths of low-cost land: check. Lots of sun and wind: check. The ability to transport green hydrogen cost-effectively to energy importing economies: check. Then you’re in the race to become one of the “renewable energy superpowers” of the low-carbon economy. A growing number of countries are assessing their renewable resources and natural attributes and positioning themselves to become green hydrogen exporters. However, not all are created equal.
Dutch transmission system operator Tennet, which also serves Germany, is planning to create flexible electricity demand and reduce grid congestion by promoting the use of smarter heating systems and heat pumps that can also be powered by solar and wind energy. According to its experts, intelligent control of heat pumps may result in the creation of between 0.5 and 1 GW of temporary grid flexibility by 2030.
Green Investment Group, owned by Macquarie, has launched Cero Generation, which will operate on a European scale and carry out both ground-mounted and commercial scale power generation projects. It will also provide integrated energy storage solutions.
UK-based Social Energy launched in Australia with the help of shareholder Shane Warne back in 2019. Now the smart energy firm is being backed with a significant investment from US-based alternative investment fund manager CarVal Investors in order for the company to rapidly grow Down Under.
Two French companies have collaborated on the development of the Osmo-Watt system, which is powered by solar panels. They claim that the technology can produce up to 100 cubic meters of drinking water per day.
