Hydrogen-heated home in Sherwood Park lays ground for low-carbon communities

On the outside, the caller location conscionable eastbound of Edmonton successful Sherwood Park looks similar immoderate different Canadian suburban home.

But inside, the home’s state-of-the-art furnace is fuelled not by the Alberta norm of earthy gas, but by axenic hydrogen — making it the archetypal of its benignant successful Canada.

Built arsenic a objection and unfastened to the nationalist for tours, “HomeOne” aims to amusement that hydrogen state tin beryllium utilized safely and efficaciously for heating buildings, portion besides being portion of the cleanable vigor transition.

The location is simply a associated task betwixt energy and earthy state inferior institution Atco and residential developer Qualico, who accidental their eventual extremity is to person each of the 37,000 homes successful Qualico’s proposed aboriginal Sherwood Park assemblage of Bremner heated by axenic hydrogen.

“We perceive from our builders that determination is simply a large woody of (public) involvement successful low-carbon living,” said Brad Armstrong, vice-president for assemblage improvement with Qualico.

“Nobody is funny successful polluting the environment, truthful I deliberation determination is simply a wide entreaty there.”

Light, storable and energy-dense, hydrogen has garnered a large woody of planetary involvement successful caller years due to the fact that it produces nary nonstop greenhouse state emissions.

Within Canada, hydrogen improvement is peculiarly charismatic successful Alberta due to the fact that of the province’s immense reserves of earthy gas.

While hydrogen substance tin beryllium produced done a fig of concern processes, including utilizing renewable electricity, the immense bulk of the world’s existent hydrogen accumulation is produced utilizing fossil fuels – successful particular, earthy gas.

A batch of the excitement astir hydrogen’s imaginable has been related to its usefulness successful the proscription oregon concern sectors.

When it comes to the decarbonization of location heating, the absorption successful North America has been connected electrification and the installation of vigor pumps, not hydrogen.

But Greg Caldwell, Atco’s manager of inferior hydrogen strategy and decarbonization, said determination are immoderate jurisdictions wherever hydrogen makes much sense.

In Alberta, for example, the province’s energy grid is already nether unit owed to the accelerated phase-out of coal-fired generation.

While determination has been a corresponding roar successful upwind and star vigor procreation successful the province, the intermittent quality of these renewable sources of energy means that during periods of utmost demand, the grid tin go dangerously abbreviated of supply.

Forecasts amusement energy request successful the state volition lone proceed to turn arsenic much radical power to electrical vehicles and the maturation of AI drives request for power-hungry information centres.

To debar blackouts during acold snaps and different periods of highest demand, Caldwell said it makes consciousness to look to hydrogen arsenic a home-heating solution alternatively than put successful monolithic enlargement of the energy grid.

Although regulatory changes volition person to beryllium made to licence it, hydrogen tin beryllium transported done the aforesaid pipelines that already proviso communities with earthy gas. And doing truthful would beryllium acold cheaper than gathering upwind and star farms large capable to grip the fewer days a twelvemonth erstwhile utmost acold causes home-heating request to spike.

“When you look astatine the standard of the situation of trying to get to an affordable, but besides a lower-carbon heating system, hydrogen comes retired arsenic the victor successful this jurisdiction,” Caldwell said.

Hydrogen location heating has been tried successful a fistful of different jurisdictions globally, specified arsenic the Netherlands, with mixed results. Some radical person expressed concerns astir the hazard of detonation oregon pipeline leaks, though Caldwell said erstwhile done correctly, hydrogen heating is conscionable arsenic harmless arsenic earthy gas.

He said the biggest drawback presently is cost. The outgo of hydrogen substance contiguous is astir treble the outgo of earthy gas, Caldwell said, though helium added homeowners would not spot their inferior bills treble since the outgo of the substance itself is lone a tiny information of a inferior bill.

The dual hydrogen-fueled gradient furnace and h2o heater installed successful HomeOne is besides much businesslike than a accepted furnace, helium added.

“I bash deliberation we’ll spot the outgo of the substance travel down with contention and with caller projects being built,” Caldwell said, adding determination are respective caller hydrogen accumulation facilities presently underway successful Alberta, including 1 by Air Products and 1 by Dow Chemicals.

In the meantime, Caldwell said helium hopes the objection location successful Sherwood Park helps amusement radical that residential heating with hydrogen is viable.

“Hydrogen is conscionable getting started,” helium said.

“It tin look a small scary economically, oregon it tin look scary adjacent technically, but what we’re telling you is we tin bash it. We tin physique it today.”
