Floating concentrating photovoltaic thermal system for carbon capture – pv magazine International


Two Norwegian firms have designed floating concentrating photovoltaic thermal know-how that produces each electrical energy and warmth. It’s supposed for use in carbon seize initiatives and supported by an industrial warmth pump system.

Norway-based analysis firm Sintef and Norwegian floating PV specialist Svalin Photo voltaic are presently creating a floating concentrating photovoltaic thermal (CPVT) receiver supposed to be used in carbon seize services. .

“The vitality requirement required for CO2 stripping might be essentially the most dominant issue governing solvent-based post-combustion extraction know-how,” Sintef’s Senior Enterprise DeveloperMartin Bellmann, spoke pv journal. “Primarily, any know-how that may considerably scale back the so-called reboiler responsibility – vitality consumption for CO2 elimination – is very wanted.”

The 2 firms describe the brand new know-how as a solar-assisted carbon seize system that in complete or partially generates the thermal vitality wanted for fuel separation.

“The proposed CPVT design is a single-axis monitoring system of the ‘linear by way of’ sort, the place rows of curved mirrors are mechanically rotated in order that the size course of the mirrors is at all times parallel to coincidental daylight and follows the each day movement of the solar,” added Bellmann. “Focus ratios of about 10 days might be achieved.”

The CPVT receiver relies on a tube with photo voltaic cell strains connected to it. The small space of ​​the CPVT receiver permits for the usage of high-efficiency PV cells. “Though these PV cells are dearer, the associated fee might be offset by lowering the world required,” explains Bellmann. “Standard crystal silicon and multi-junction cells must be thought of. Afterwards, the price-to-performance ratio shall be evaluated when the prototype is accomplished and working and we’ve got collected sufficient knowledge from the take a look at trials.

In accordance with Sintef, the environment friendly thermal administration of the CPVT receiver is achieved by the warmth switch fluid surrounding the tubes. The chilly fluid enters the pipe community on the inlet which collects the warmth from the receiver and retains the PV cells at a low temperature. The collected warmth is then transferred to a high-temperature warmth pump (HTHP), which acts as an auxiliary thermal vitality booster that upgrades waste warmth and low-temperature warmth from the receiver for steam manufacturing. within the Carbon Seize Storage (CCS) course of.

{The electrical} energy produced by the PV cells might be equipped to the grid or used on to energy the HTHP or different auxiliary processes within the CCS course of.

Sintef is presently engaged on the design and improvement of the Svalin Photo voltaic plant and plans to buy the elements and construct a pilot facility in the summertime of 2024. “Initially, the plant shall be examined on dry land as a part of present carbon seize facility operated by Sintef in Tiller, simply outdoors Trondheim, “mentioned Bellmann. “To attain a cost-efficient design of the CPVT system, it is very important perceive if the annual vitality manufacturing, each thermal and electrical, can compensate for the extra prices of set up, monitoring and upkeep. “

The demonstrator shall be a part of the EU-funded mission “Remodeling energy-intensive course of industries by integrating vitality, course of, and feedstock flexibility” (TRINEFLEX), with a complete funds of € 19.3 million ($ 21.2 million) and consists of 28 companions.

Some Sintef researchers have lately developed a floating construction for offshore PV, a a high-temperature industrial warmth pump that may work with pure water as its work medium, and a floating photo voltaic platform to be used in aquaculture initiatives.
