The Hydrogen Energy System provides a safe and compact way of storing green hydrogen, which powers the region’s first zero-emission building. We believe this can be a significant contributor toward Singapore’s climate change pledge to cut national emissions intensity by 36% below 2005 levels by 2030.”In urban places such as Singapore, due to limited land and inconsistent solar energy, achieving zero emission with 100% renewable energy is extremely challenging.The buildings and building construction sectors combined are responsible for nearly 40% of total direct and indirect CO2 emissions, according to the International Energy Agency.While there have been other energy systems using hydrogen as a fuel, the key challenge of hydrogen lies in having a storage solution that is safe for deployment in highly-urbanised areas such as Singapore.The system uses special metal alloy as a storage medium to bond with hydrogen. This allows for the storage of a large volume of hydrogen at a much lower pressure over a long period of time without any deterioration.SP is working with Marubeni Corporation and Tohoku University on the Hydrogen Energy System with special metal alloy storage tanks from Japan, and to customise and integrate it for use in Singapore.More: Southeast Asia welcomes first zero-emissions building Southeast Asia welcomes first zero-emissions building
Source: Sky Sports Arsenal are close to completing the signing of midfielder Willian from Chelsea on a three-year deal.Arsenal moved into pole position to sign the Brazil international, whose Chelsea deal expires later this month, by offering a three-year contract earlier this week, and are on the verge of beating off competition from Barcelona and Inter Miami.Along with the length of the deal, joining Mikel Arteta’s rejuvenated side and the chance to work with fellow Brazilian Edu are the reasons Arsenal are favourites to secure Willian’s signature.Despite wanting Willian, who turns 32 on Sunday, to extend his stay at Stamford Bridge, Chelsea have refused to offer more than a further two years – and the chances of him being a Chelsea player when the new season begins in five weeks look remote.Willian made 47 appearances for Chelsea in all competitions and finished the season in fine form, with four Premier League goals after the restart taking his tally for the season to nine.
