00:08 Over three years ago we aspired to make a strategic investment in both green energy

00:13 and out of season soft fruit production.

00:17 This has now become a reality and we have installed what we believe to be Europe's largest

00:23 river source heat pump to heat soft fruit crops to produce fruit out of season offsetting

00:28 imported product.

00:31 I am proud to say that our team of dedicated people have now taken the concept of this

00:37 innovative process to finish build.

00:43 We are at Guslunds Yolding river source heat pump river station.

00:53 Water will get at the first stage extracted at the river station and go through the heat

00:58 exchangers and we release the water back into the Metway river.

01:05 It will produce 10.6 megawatts of energy.

01:09 That is the equivalent of the energy produced by 106 car engines.

01:19 We left the river station in Guslunds energy centre.

01:23 As water comes from the river station we take with a little bit of temperature on the water

01:29 we manage to heat water up to 45 degrees with the six heat pumps we have and circulate that

01:37 out to the greenhouses.

01:43 The size of the production site is currently 6.5 hectares with plans to evolve to between

01:48 10 and 15 hectares.

01:50 This will be used to grow over 150 tonnes of raspberries, 300 tonnes of blackberries

01:55 and 200 tonnes of strawberries.

02:02 So we are at the final stage in the greenhouse where the water comes from the plant room

02:07 from the heat pumps at 45 degrees and will get re-sent back to the plant room to get

02:12 reheat and circulate back to the greenhouse again.

02:17 Each aisle has this closed loop system which circulates through each aisle and the greenhouse.

02:25 In a normal polytunnel or outside this would only be a cane but in the greenhouse these

02:30 plants are a lot more advanced.

02:35 To stay true to our commitment to innovate and reduce carbon emissions we have used this

02:40 green technology to grow berries out of season supporting a British grown ethos, clean energy

02:46 and less waste.

02:50 The dream is now a reality but the journey has only just begun.

02:55 So the leaves have died.

03:20 We are trying to explain a little bit about how this works.

03:41 We then pass that 4 degrees into the refrigerant on this side of the heat pump.

04:03 That gas then passes into the secondary side of the heating machine where we then pass

04:09 that high temperature heat into the water that we then get sent to the greenhouse.
