f1 technology halves diesel use of hs2 tower crane

an hs2 tower crane is trialling era advanced for system 1 (f1) to noticeably cut gas intake, carbon emissions and enhance air fine at one among its london construction web sites
an hs2 tower crane on the station’s euston methods web page is being powered with the aid of a 200kva diesel generator – much less than half of the dimensions of its regular 500kva diesel generator to boost masses of as much as 24 tonnes.

the generator’s energy difference is bridged by means of pairing it with an power-storing flywheel system developed and furnished with the aid of silverstone-based engineering specialist punch flybrid.

included inside the punch flybrid-provided unit, the flywheel, measuring simply 35cm in diameter, is housed in a vacuum chamber to all however do away with energy-sapping resistance that might result from touch with the air.

punch’s flybrid’s flywheel suits the electricity of larger turbines through using the 200kva generator’s surplus electricity in the course of the crane’s low load durations to price the spinning flywheel to very high speeds, equivalent to a ground speed of 550mph. the kinetic energy stored by means of the flywheel can then be fast released to support the generator whilst the crane needs most strength to boost heavy hundreds.

it may perform up to 10 million charging cycles in comparison to a few,000 of a regular electric powered automobile battery.

how is the technological know-how, evolved for f1 is being applied to hs2?
tobias knichel, punch flybrid md, defined:

“in motor racing, a groups’ quest for higher overall performance spurs the look for extra performance – essentially doing greater with much less. racing vehicles usually accelerate and brake around 500 instances during a 90 minute f1 grand prix. each time the automobile brakes into a nook at high strength our flywheel gadget spins up, storing energy that is then released quickly to reinforce acceleration overall performance as the auto leaves a bend.

“we developed our flywheel technology to improve performance and efficiency at the very top of the automotive industry, however its fundamentals suggest there are possibilities to set up its advantages in different sectors. that’s why we’re very pleased to have an opportunity to utilise the technology for the development enterprise beneath hs2’s innovation programme.”

hs2 innovation manager, rob cairns stated: “handing over britain’s zero carbon, excessive pace rail community for the 21st century is a countrywide endeavour that is drawing on abilties and technology each in and beyond the rail and construction sectors.

“our trial paintings with punch flybrid is every other top notch instance of ways making an investment in long-term national infrastructure programmes creates opportunities to draw on era from throughout the economic system that could doubtlessly release sizable benefits for our enterprise.”

commenting, innovation lead for rail at innovate uk, kelvin davies stated:

“innovate united kingdom is extremely joyful to work with hs2 inside the shipping of innovation for this prestigious programme, and through this collaborative running a new courting among hs2 with punch flybrid has created the possibility to discover the capacity supplied by means of a attempted and examined automobile technology to store fuel, reduce fees, lessen co2 emissions and create opportunities for future economic boom in the excessive-price manufacturing and engineering sectors.”

the web site is operated through skanska costain strabag joint task (scs jv)
the web page, in which hs2’s london tunnels surface is, is operated by way of the venture’s tier one civils contractor skanska costain strabag joint project (scs jv).

scs jv handling director, james richardson said:

“scs jv is dedicated to lowering our environmental footprint by using figuring out improvements like this flywheel technology, which has without delay halved our diesel consumption of certainly one of our cranes working at our euston techniques website.”
