Strawberries saved for winter thanks to pioneering British invention
Plants installed in August will begin yielding fruit within weeks
TL;DR
- University of Lincoln's greenhouse is the first in Britain to use geothermal energy for strawberry cultivation.
- Geothermal heat is drawn from 200-meter-deep boreholes, maintaining a constant 17C for year-round production.
- This method offers approximately one-third cost savings compared to natural gas heating.
- The technology could boost UK food security by increasing domestic fruit and vegetable production.
- Geothermal resources are available in various UK regions, including Lincolnshire, Scotland, and Cornwall.
- Recent weather extremes in supplier nations have exposed UK food supply chain vulnerabilities.
- The university facility will distribute its strawberries to local food banks and the campus canteen.
- Future plans include cultivating tomatoes, peppers, cucumbers, and flowers, with potential for waste heat from data centers.
- British domestic fruit production currently accounts for only 16% of national consumption.
