MACLEC Mint Group
Provider of the only SHK Turbines globally
Generate Hydrokinetic Power From any running stream globally
Solution Concept
SHK-EMU is a close-loop energy storage capable to hold surplus power as potential energy in terms of water pumped to its upper reservoir.
For power supply, the stored water gets channelised through low gradient high velocity canals fitted with SHK Turbines and generated power then fed to the grid with more than 85% round trip efficiency. The discharged water gets accumulated in the lower reservoir using the gravity and gets recirculated in the next charge-discharge cycle.
SHK-EMU can act as giant battery for Post generation energy storage and play key role in transition towards carbon-neutral economy.
By storing this excess electricity in SHK-EMU, utilities can manage peak energy demand while decrease their individual carbon footprint considerably.
SHK-EMU also provide ancillary benefits such as firming capacity and reserves (both incremental and decremental), reactive power, black start capability, and spinning reserves which makes it perfectly suitable and relevant for the challenge selected.
Market Opportunity
MACLEC is getting early traction from large energy CPSUs globally for SHK-EMU which establish its relevance in present global energy transition.
The global post generation energy storage market size is projected to surpass around US$ 435.32 billion by 2030 and growing at a CAGR of 8.4% from 2022 to 2030 which makes SHK-EMU a billion-dollar worthy Unicorn Venture.
MACLEC is planning to establish a gigawatt factory for bulk production of SHKEMU to capture at least 10% Global Energy storage market in next 5 years.
While all utilities are struggling to secure supply of batteries as well as to complete formalities for traditional pump storage projects, MACLEC’s SHK Turbines are already in operation since 2020 and completed all trials, scale-up R&D, regulatory approvals and ready to be deployed as close-loop energy storage.
The Technology Advantage
SHK-EMU is very low tech, globally deployable bulk energy storage system which is based upon SHK technology.
The SHK-Turbines are 100% indigenously invented in 2013, patent-granted in 2020 & successfully in operation, designed, developed, manufactured in India which make it low cost in production and simple in O&M.
Developed countries can immediate deploy it for its own use followed by supplying to other utilities under BOOT or EPC+AMC mode jointly with MACLEC.
Due to its geographical independence, the SHK-EMU can be deployed in any existing pond/non-hydro-powered dam/reservoirs/holding tanks/waste water treatment facilities/etc. without any major civil/structural changes.
To utilise the coastal zones, SHK-EMU can be deployed just next to the ocean by constructing only one upper reservoir and utilising ocean itself as lower reservoir.
With this huge scope in Developed countries and globally, SHK-EMU can enrich its Investor’s strategic value and providing a significant edge over its competitors to dominate Energy Storage Segment.
Product Advantage
The batteries and traditional pump storage cannot supply power during charging. But SHK-EMU can anytime supply the firm power, even while charging because the charging medium (water pumps) is separate then power generating turbines. Due to this advantage, SHK-EMU can operate in continuous charge-discharge mode and can perform more than 2 use cycles/day. This advantage further enhances the overall capacity utilisation factor and increases the overall project revenue stream.
Product Readiness
Evidence for Market Validation
MACLEC completed field trials b/w 2014-2015 with HRED-IITR and ONGC Energy Centre.
From 2016 to 2018, the Scale-up R&D was conducted in dedicated labs, field trials in natural streams/canals followed by CFD validation.
From 2019 to 2020, a commercial demo project have been deployed at upper Ganges canal. From 2021 onwards MACLEC has a commercial deployment at Jim Corbett national park running successfully.
SHK Turbines are WWF’s climate solver Awardee (2018), Best global green business idea by European-Union (2019), X-factor invention of Earth by NASA (2020), Solution for SDG Goals Award by BRICS (2021), Grass-root Tech for SDG-7 by UNDP, etc.
