AQUATHERMAL STRATEGY DEVELOPMENT
EXTRAQT, founded in July 2021, is an engineering start-up with the ambition to boost our society towards sustainable heating and cooling. Our company focuses on aquathermal heating & cooling, a sustainable alternative to natural gas where heat pumps are used to extract thermal energy from surface water (rivers, lakes, canals) and provide buildings with heat/cold.
EXTRAQT develops energetic models (‘digital twins’) of rivers and lakes to estimate the potential of these sustainable thermal sources. Based on our feasibility studies, we design the technical concept for the aquathermal installation. Our digital twins and analyses always respect the boundaries of the waterbody’s ecosystem.
50% of global energy consumption comes from heating and cooling, but only 14% is generated sustainably. A dominant renewable source is currently overlooked, even though 50% of the world population lives within 3km of it: surface water. An emission reduction of 65% is possible by sustainably harvesting thermal energy stored in rivers, canals, and lakes. To extract this energy, while preserving these essential sources of nature, detailed analyses are necessary. EXTRAQT uses digital twins of the waterbodies to create in depth thermal impact assessments and guide regions, cities, and institutions to make a step change towards sustainable heating and cooling.
AQUATHERMAL HEATING AND COOLING
By using heat pumps, thermal energy can be extracted from rivers and lakes to heat & cool surrounding buildings
50% of the world’s population lives closer than 3 km to a river or lake. These waterbodies can be one of the most dominant sources in a sustainable energy transition
At EXTRAQT we develop aquathermal strategies with digital twins of rivers and lakes while always respecting their ecosystems
65% CO2 emission reduction from heating with gas when using grey electricity
99% reduction when using green electricity
