In the heart of Poland''s Oława EKO Energy Cluster, a groundbreaking project is currently being developed to provide greener, cleaner energy. The company PROMET-PLAST has embarked on a mission to build a smart energy grid with gravity energy storage– an emerging technology that uses suspended solid weights to store and release energy. Gravity energy storage is a cleaner alternative to traditional batteries, with the ability to reload energy 10–20 times per day.
This innovative project will integrate the company''s existing energy system to ensure a consistent energy supply that adapts swiftly to volatile energy sources. PROMET-PLAST''s smart energy grid has the potential to increase renewable energy use in Europe and curtail greenhouse gas emissions. The project offers stability and sustainability in a time when energy independence is more crucial than ever. In September 2023 the company received a long-awaited patent further confirming the innovative nature of this technology.
Recognising the project''s potential impact on Europe''s green energy sector, PROMET-PLAST sought guidance from the EU initiative Green Assist. As a result, between July and December 2023, the company received free tailored advisory support from hand-picked experts to boost its green venture.
The project''s chief financial officer, Adam Wąsiewicz, said: ''I did not expect to encounter such committed individuals who not only sought to understand my project but also provided constructive assistance.''
PROMET-PLAST''s request for support was multi-faceted. Green Assist helped the company to develop a robust business model and financing strategy. Offering independent opinion, the initiative experts helped the company to approach the financial market and investors. They were also providing a comprehensive analysis of market dynamics, focusing on the Polish renewable energy landscape.
Adam added: ''Green Assist helped us to gain a better understanding of the expectations of potential investors. The questions posed by Green Assist experts revealed several threats that we were not aware of, allowing us to safeguard against them.''
In addition, PROMET-PLAST asked Green Assist for support with presenting its project to EU institutions and the wider public. The project aims to bolster its investment appeal, seeking advice on how to navigate the challenges inherent to an innovative venture.
''The materials prepared by the Green Assist team are top-quality, making conversations with investors much smoother. I also appreciate that all tasks are completed within the agreed deadlines,'' noted Adam.
Green Assist also supported PROMET-PLAST with designing the final reporting and satisfaction surveys, ensuring that the project remains on course and responsive to the ever-evolving demands of the green energy sector.
''Meetings with the Green Assist team have consistently been constructive, and we have never wasted time on unnecessary discussions. I am grateful that Green Assist listened to us and understood our needs. I would highly recommend collaborating with the Green Assist team. They are true professionals,'' said Adam.
Green Assist aims to build a pipeline for high-impact green investment projects in sectors related to biodiversity, natural capital and circular economy, as well as in non-environmental sectors.

Two startups presenting gravity-based energy storage technologies for commercialisation have signed partnerships with major players in engineering and mining.
The UK''s Gravitricity and Australian company Green Gravity have this week both announced collaborations that will enable them to scout out potential sites where existing or former mine shafts could be repurposed to host their gravity storage tech.
Both companies'' energy storage system design consists of an underground shaft, in which a heavy weight is lifted to the top of the shaft using electricity as the system ''charges''. When discharging, the weight is lowered, driving generators.
Gravitricity has signed an agreement with ABB to explore how the global engineering and electronics company''s experience and knowhow with hoisting equipment could be applied to gravity storage.
Headquartered in Edinburgh, Scotland, Gravitricity has to date built one functioning commercial-scale demonstrator, a 250kW project near its offices which uses two 25-tonne weights and went into operation in 2021.
The company claims its technology GraviStore is suitable for both short-duration, high power energy storage applications and long-duration, high energy applications. By using existing or new mine shafts dug into the ground, the amount of land needed at surface area is limited and Gravitricity claims GraviStore has an expected 50-year operational lifetime with no degradation or limits to cycle life.
ABB has deployed mine hoists at more than 1,000 sites globally and the company will make R&D, design and engineering teams available to collaborate with the startup on design, engineering and operations of mine hoists and the associated mechanical, electrical and control technologies required for hoisting.
The pair will work on feasibility studies for applying existing hoisting technologies to gravity storage, with Gravitricity''s own experts contributing knowledge of grid compliance and control systems. ABB meanwhile will also work to identify suitable sites for GraviStore facilities.
Gravitricity has to date been in discussions for potential projects in Czechia, the US and Germany, while the UK government granted the company some funding to investigate sites for a possible demonstration project in India. The company expects a typical project site to be around 20MWh storage capacity.
Green Gravity meanwhile has signed a Memorandum of Understanding (MoU) with mining company Wollongong Resources to study the application of gravity-based energy storage at eight potential sites in Australia.
The facilities could host up to 100MWh of storage in the Illawarra, a coastal region of the greater Sydney metropolitan area of New South Wales (NSW).
The Illawarra is earmarked for one of the state''s Renewable Energy Zone (REZ) developments, a multi-gigawatt, multi-technology clean energy hub.
In 2022, the NSW government received a "tremendous" level of interest from prospective developers of solar PV, wind, battery storage, pumped hydro energy storage (PHES) and green hydrogen at the Illawarra REZ. Green Gravity said its gravity storage projects could support the REZ''s development.
Green Gravity and Wollongong Resources will work together to size and design gravity storage systems for eight decommissioned and inactive mine shafts in the region. The partners will also assess how repurposing as energy storage could be a path forward for coal mining operations as they are decommissioned.
Green Gravity has a similar agreement in place elsewhere in NSW, with another coal mining company, Yancoal, while the startup recently began working in Romania to investigate how storage systems could be placed in mine shafts at the country''s Valea Jiului mining region.
Green Gravity formed a technology partnership last year with engineering services company GHD, aimed at developing new applications for the Green Gravity technology and accelerate its commercialisation.
Energy-Storage.news'' publisher Solar Media will host the 9th annual Energy Storage Summit EU in London, 20-21 February 2024. This year it is moving to a larger venue, bringing together Europe''s leading investors, policymakers, developers, utilities, energy buyers and service providers all in one place.

There''s a big hole in the ground at a site on the eastern side of the Czech Republic. It''s near the border with Poland, to the north, and Slovakia, to the west. Right now, that hole looks like a dark pit of nothingness. But in it, several researchers see a potential solution to a looming energy problem.
