The company believes that GSHP can be used to deliver multi megawatts of power and cooling and has direct application to the data center market.
The energy services company (ESCO) will be used to fund the installation and maintenance of environmentally friendly systems to heat and cool new buildings throughout the UK and Europe and is currently in the market to raise £10 million in equity from investors, it said in a statement.
GSHP systems use solar energy stored just below the earth's surface to heat buildings, and can also cool buildings by transferring heat from buildings to the ground.
"If a data center is using pushed air for cooling, which most are, it can be retrofitted to use GSHP. In terms of capacity it is a question of how many holes you want to put in the ground," said John Flavell Smith, chief operations officer at Greenrock. The company is actively pursuing data center architects, owners, builders and operators. Ground source heat pumps.
The geothermal energy used by GSHP does not originate from the earth's core but from incident solar energy that over millennia has become trapped in the earth's near surface. Consequently, even in relatively shallow ground, the temperature ranges between 8º - 12°C throughout the year. GSHP systems tap this energy to provide both heating and cooling. This energy is captured and delivered at the point of use unlike electricity generation from renewable sources such as wind or wave power which needs to be exported to far flung centres of population, requiring significant electricity grid infrastructure, with its transmission losses and high costs.
In heating mode, a typical system pumps a liquid through a collector loop, which is fixed in the ground. The liquid enters the collector loop at a low temperature and returns at a higher temperature, where the energy is extracted in a heat exchanger and used to heat the building.
For cooling, the heat pump works in reverse, extracting heat from the building and dissipating it in the ground. Combined heating and cooling systems increase both utilisation of plant and improve efficiency: the ground is used as a heat sink whilst cooling and the energy deposited can later be drawn upon during the heating cycle.
