Hyme Vitality has awarded Semco Maritime an engineering, procurement, and development (EPC) contract for companies for the 1.6 MWh Molten Salts Storage (MOSS) Mission in Esbjerg, Denmark. The long-term vitality storage plant can be linked to the grid and can be used to show and take a look at the molten hydroxide storage expertise in a sensible setting.
Hyme Vitality, a derivative of Denmark’s Seaborg Applied sciences, has partnered with Semco Maritime to construct a molten salt thermal vitality storage demonstrator on the Gjesing Varmeværk heating plant, owned by regional utility Din Forsyning, within the Danish port of Esbjerg.
“The MOSS demonstration plant is the primary vitality storage plant ever constructed with molten hydroxide salts. It would include a 1.6 MWh storage unit, which can lay the groundwork for future services within the GWh vary ,” requested Emil Løvschall-Jensen, CEO of Hyme Vitality, was informed pv journal.
He stated that the aim of the plant is to show and take a look at the corporate’s molten hydroxide storage expertise in a sensible setting.
“The plant can be examined to show our element integration, validate our system design, acquire insights into optimum supplies and elements, and show system operation and management,” he stated.
Subsequently, the demonstration plant will solely be used to supply warmth. Nonetheless, it’s not a part of the scope of the challenge to supply warmth to the Esbjerg district heating system, the corporate defined.
Hyme’s vitality storage expertise shops electrical energy from renewable sources at 700 C molten hydroxide salt for as much as two weeks. It’s based mostly on a two-tank storage design developed for concentrated solar energy (CSP) vegetation and Hyme’s proprietary salt hydroxide corrosion management expertise.
When charging electrical energy from renewables is transformed to warmth by means of electrical heaters. The salt from the chilly tank is circulated by heaters and heated from 350 C to 700 C, then saved within the scorching tank.
Throughout discharge, the salt from the new tank circulates to the steam generator, the place the vitality is transferred to the water, producing excessive temperature steam. The steam can be utilized immediately in an industrial course of or used to energy a turbine and produce electrical energy and district heating. After that, the cooled salt is pumped again into the chilly tank till the subsequent charging cycle.
Hyme’s storage expertise is scalable and a 1 GWh facility with sodium hydroxides ought to produce energy and warmth for almost 100,000 households for 10 hours of discharge, the corporate stated.
Since sodium hydroxide may be produced at low price from seawater as a byproduct of chlorine manufacturing, the corporate calculates that it’s six instances cheaper than customary salts used for storage.
Hyme, based in 2021, is engaged on one other demonstrator on the island of Bornholm in Denmark. The corporate’s 10-15 MWh molten salt storage facility can be a part of a scalable hybrid storage system that can even characteristic a flywheel storage system offered by QuinteQ Vitality and recycled lithium-ion batteries offered by PLS Vitality Techniques.
The Bornholm challenge known as 2LiPP goals to supply insights into attainable repurposing pathways for mixed warmth and energy (CHP) vegetation. It would present warmth, energy, and companies along with the native community.
In November 2022, the Danish firm signed a cooperation settlement with Energy Engineering Consulting Joint Inventory Firm 2 (PECC2) to develop and construct at the very least 2 GWh in 2030 and at the very least 6 GWh in 2035 of thermal vitality storage tasks in Vietnam.
For the MOSS Mission, engineering is predicted to be accomplished within the second quarter of 2023, with the subsequent section of set up ending within the fourth quarter. Hyme acquired help from the Danish Vitality Company to construct the pilot plant.
“The storage system in Esbjerg is linked to the common grid, and never immediately linked to renewable sources. When charging extra electrical energy (when the worth is low) within the storage system, the electrical energy is normally from renewable origin,” says Løvschall-Jense.
That is attainable as a result of the Esbjerg space is understood to be a good geographical space for wind vitality, with giant offshore tasks already in operation.
The demonstration plant will solely produce warmth, not electrical energy. Additionally, it’s not a part of the scope of the challenge to supply warmth to the Esbjerg district heating system.
“We matured the MOSS challenge final yr and we’re prepared to start out the development section with Semco Maritime,” concluded the CEO.
Along with the MOSS Mission contract, the companions agreed to discover alternatives to collaborate on future bigger Hyme tasks, the place its long-term thermal vitality storage resolution permits utilities and trade to decarbonize. in warmth and energy technology.
