German engine maker MAN Vitality Options‘ industrial-sized warmth pumps will produce 350,000 MWh of warmth per 12 months and heat 25,000 Danish households utilizing offshore wind energy and seawater.

Industrial-sized warmth pumps

The seaport city of Esbjerg, Denmark, has a goal of web zero by 2030, and Kenneth Jørgensen, venture director at Danish utility DIN Forsyning, stated:

We’re phasing out coal-fired warmth and changing it with carbon-neutral district heating produced from wind and seawater.

DIN Forsyning can be utilizing two of MAN Vitality’s electro-thermal power storage warmth pumps. They’re the primary of their variety to offer zero-emission thermal power on an industrial scale, they usually’re powered by clear electrical energy created by native wind generators. They’re anticipated to come back on-line this fall.

How they work

Seawater is drawn from the harbor, and thermal power is extracted earlier than the water is pumped again into the ocean. Carbon dioxide, the refrigerant, is warmed up by the seawater and vaporized, then it’s compressed, and it heads to a warmth exchanger, the place it reaches a most temperature of 150 C (302 F). It is going to ship water to town’s district heating community at 90 C (194 F).

Karl Böhle, MAN’s senior venture supervisor, stated:

The specialty of the system we’re putting in is that we’re utilizing seawater as a warmth supply, CO2 as a refrigerant, and a hermetically sealed, electrically-driven compressor to generate warmth.

One of many distinctive options of this warmth pump resolution is that its use of extreme wind energy can steadiness the grid if required.

With the ability to retailer warmth implies that, in contrast to {an electrical} grid that must be balanced, the warmth pump’s manufacturing doesn’t should match its consumption. Extra electrical energy might be offered again to the grid, which suggests the enormous warmth pumps present cleaner and cheaper warmth and electrical energy.
