Sustainable 'vroom' at NY Formula E circuit

The Oilholic has spent the last two days watching frantic motorsport action of a different kind here in the Big Apple accompanied by background vroom that's milder, greener, zero-emission and most certainly less audible compared to petrohead outings. 

Welcome to Formula E – the world's first fully electric global motor racing series – with several ex-Formula 1 converts both in and outside the drivers' cockpit. The 2.37km racetrack with 14 turns in Brooklyn's Red Hook neighbourhood, adjacent to the cruise ship terminal, saw twenty-two cars compete for 45 mins plus a final lap in the championship's concluding race in Sunday.

After all the racing, crashing, jostling and competing was done and dusted, Dutchman Robin Frijns claimed the race victory, while Briton Alexander Sims, and Swiss driver Sebastien Buemi finished in second and third respectively.

Of course, the day in the New York sunshine belonged to Frenchman Jean-Eric Vergne of Team DS Techeetah, who became the first double Formula E champion at the season's finale. 

Going into Sunday's (July 14) race, Mitch Evans and Lucas Di Grassi were championship contenders, and both needed at least a race win to claim the title. However, Di Grassi's attempt to overtake Evans ran them both into the wall, handing their rival the advantage. The action certainly delighted the competition's backers. 

Not least, Swiss electrification and robotics giant ABB; the headline sponsor of the Formula E circuit. The company feels the sport is a joy for motoring purists. Consider this - the 2019 championship had eight different winners in the first eight races, although Vergne ultimately surged ahead with a second victory of the season in Monaco.

From ABB's perspective, the obvious brand equity and exposure aside, the company is using its track connections and participation as a "fertile testing ground" for global mobility's inexorable march to a low carbon, zero-emission future. 

Frank Muehlon, Managing Director, EV Charging Infrastructure at ABB, told the Oilholic that the company's association with the sport is not just a routine sponsorship but a vital partnership. "From the circuit safety cars to all the teams, our charging infrastructure is at the heart of it all."

As headline sponsor, the company partners with all racing teams and offers bespoke high power charging equipment to sister races such as Jaguar Land Rover's I-Pace e-trophy, which runs teams of its I-Pace electric SUV model before most, if not all, of the Formula E races. 

"Advanced data gathered at this very race, and others over the course of the season, feed into our research and development efforts run from three global labs (two in Europe and one in China)."

Muehlon added that ABB is automaker "agnostic."

"We are an equal partner to all, and by that I don't imply just the teams you see on track, but anyone in the global automaking world who is getting serous about electric vehicles. Let's face it, that's pretty much every global automaker these days."

At the heart of it all is promoting e-mobility, bringing down charging times and enhancing battery performance. On the latter point at least, Formula E offers a case in point. Not that long ago the drivers needed to change cars midway through the race as the battery could not cope with the rapid drain on it. 

However, with an enhanced battery life and back up charging technology, the current Generation 2 Formula E cars last the length of a 45 minute race plus an additional lap.

Looks like we are in for an 'electrifying' progression ahead when it comes to electric mobility, both on and off-track, ABB is certainly counting on it. That's all from the Brooklyn racetrack folks with no petroheads around.

A Peek at ‘Ice Banks’ under 30 Rock

The Oilholic finds himself back in New York, US for the finale of the ABB Formula E 2019 season. But before watching the FIA-backed electric-mobility powered thrill ride, this blogger paid a visit to the Big Apple's iconic 30 Rockefeller Plaza building known to most locals as 30 Rock, rather than its relatively new christening as the Comcast Building.

Most visitors head to the "Top of the Rock", i.e. the building's observation deck to soak in views of the City's amazing urban sprawl and spectacular skyline. But unlike most, yours truly headed to the bottom to get a glimpse of a fascinating endeavour in energy efficiency.

You won't need to be an engineer to work out that the 30 Rock, and by extension the wider Rockefeller Center – a large complex of 19 buildings covering 22 acres between 48th and 51st Streets – consume copious amounts of power, more so in the summer months with air conditioning on full blast. For a city that consumes close to 11,000MW to 15,000 MW of power per day, keeping things in check is a matter of priority starting right with its Skyscrapers.

It is with this objective that the good folks at 30 Rock set about it using ice! The concept is simple yet brilliant in equal measure – a solution to the summer's searing heat by freezing water at night (when power is cheaper, produced efficiently and loads are lighter) and then using it to cool the building as it melts the next day during peak load periods.

Much of that infrastructure is housed below 30 Rock glanced at by the Oilholic, courtesy of ABB, with the electrification and robotics giant inheriting a legacy service and maintenance contract for 30 Rock from General Electric, following the Swiss company's takeover of its American counterpart's industrial solutions unit GEIS in 2018.

Dubbed "IceBank(s)" by their manufacturer Calmac, the ice freezing and melting units now form the centrepiece of innovation at the heart of 30 Rock's legacy power systems dating back to the 1930s. According to ABB's Senior Manager in-charge of the contract James Payne, the system's thermal energy storage premise lessens stress on the power infrastructure since consumption during the critical peak hours (which for 30 Rock would be between 11-1pm and 4pm-5pm), and shifts the demand dynamic to the night-time.

Away from prying eyes, legacy systems intertwined with state-of-the-art digital systems and a maze of pipes, pumps, tanks, wires and fuses get to work day in / day out for a building that has some pretty demanding tenants – not least broadcaster NBC. 

The ICE system has seen constant improvements since 2012 has proved itself to be pretty reliable. As for the sheer numbers, according to a spokesperson, the Rockefeller Center as a whole is served from its 30 Rock hub by a central chilled water plant containing 14,500 tonnes of steam and electric driven chillers.

The water is distributed around the entire building campus through a "main water loop" which travels around the perimeter of the site. Six primary pumps are located in the main plant, four having 6,000 GPM capacity at 125hp and two having 2,000 GPM capacity at 50hp.  Each individual building has pumps which then draw off of the primary loop and send the main plant's chilled water to heat exchangers located within each building.

There are seventeen "primary chilled water riser pumps" which range in size from 1000 GPM at 40hp up to 3500 GPM at 200hp. The secondary side of the heat exchangers have pumps which serve the air handlers and fan coils which serve the tenant spaces, and individual building pumps draw chilled water to heat exchanges located within each building.

If all that sounds a bit heavy, then simply consider this – power costs have come down by as much as 30% on annualised basis using such thermal storage techniques. The concept is not new and has been around for nearly 15 years, but New York is getting seriously serious about it these days.

Beyond the Rockefeller Center, Goldman Sachs, Morgan Stanley and Bank of America towers have all gone down the thermal storage route, with rising take-up in the last five years. ABB, which has been growing its footprint in New York state, says advanced digitisation can work alongside legacy power systems to create an efficient, serviceable power ecosystem incorporating thermal storage, as more and more buildings opt for sustainable solutions and work towards lowering their carbon footprint.

ABB's viewpoint is shared by real estate firm Tishman Speyer, ventilating and cooling systems maker Trane and of course IceBank manufacturer Calmac – all of whom are drivers of thermal storage adoption at 30 Rock. Let's see where the market goes, but the next five years should be interesting. That's all from 30 Rock folks, its time for the Formula E racetrack now!

A rollover and a poem for OPEC

As widely anticipated, OPEC did indeed rollover its ongoing oil production cuts of 1.2 million barrels per day (bpd), set in place with 10 other non-OPEC producers for another nine months to March 2020.

The announcement was accompanied by a "charter of co-operation", even a poem about that charter (see left, click to enlarge), in-house conjecture that US shale production would eventually decline like the North Sea but not much by way of how the cartel intends to exit from its current output cuts strategy. 

Here is the Oilholic's analysis via Forbes. More to follow via other forums and publications. In a nutshell, one's price outlook for crude remains bearish and 2020 could get even more ugly. There is also little on the horizon to ditch $65-70 per barrel average price range for Brent, and $55-60 per barrel price range for WTI, with both likely to be at the lower range rather than the upper range. That's all for the moment folks! Keep reading, keep it 'crude'!
