The Hydrogen Stream: Rolls-Royce unveils hydrogen combustion engine for CHP
Rolls-Royce has started developing a hydrogen combustion engine for combined heat and power (CHP) systems in Germany, while Lhyfe has installed a 1 MW electrolyzer for Deutsche Bahn.
DNV’s solar asset modeling platform launches in Europe
Solar Resource Compass provides users with an online service that can deliver indicative energy production estimates for any solar project, including the comparison of multiple irradiance datasets and the calculation of site-specific losses for dust and snow. Many features are still being beta-tested in Europe, but DNV tells pv magazine it is planning to roll out the tool in most of Asia, the Middle East, Latin America and Oceania in 2024.
Australian grid operator to boost system strength with synchronous condensers
Transgrid – the owner of the power grid in New South Wales, Australia – aims to roll out up to 14 synchronous condensers and 4.8 GW of batteries with “grid-forming” capability to stabilize the electricity grid as coal-fired power plants retire and more renewables come online.
Woltair expands online heat pump, solar PV platform
After finding growth in its home market and Poland, Czech Republic-based Woltair raised venture capital to expand its heat pump and solar PV software platform, used by both installers and homeowners, into Germany and Italy.
Component sizing key for upscaling high-temperature heat pumps
A group of researchers has investigated how high temperature heat pumps may be upscaled for industrial applications and has found that larger setups promise higher efficiency. They also found that smaller setups show a better coefficient of performance resulting from design effects.
First attempt to build inverted perovskite solar cell based on nickel oxides delivers 20.06% efficiency
Scientists in Colombia have proposed to develop inverted perovskite solar cells with a hole transport layer based on indium-doped nickel oxide. The result is a champion device achieving an efficiency of 20.06% and showing remarkable stability.
Rooftop PV reduces building retrofitting costs by up to 50%
Cambridge researchers have analyzed the benefits of installing a PV system on the roof of an apartment building in addition to energy refurbishment and have found that photovoltaics, especially if combined with heat pumps, makes retrofit projects more affordable.
