EnergyNest - enable clean energy now
Renewable energy has challenges. The sun doesn't always shine and the wind doesn't always blow. Current energy storage solutions are complex, expensive and hard to maintain. EnergyNest is the solution.
The Problem Facing the Renewable Energy Market
There is a consensus across many energy industry experts that the renewable energy market faces some challenges. There have been incredible advances in renewable power generation techology driven by carbon emission targets which has led to a sustained increase in the use of renewables. Industry commentators see fixed and variable costs for wind and solar decreasing by a rate which puts traditional power generation under pressure - some expect to see fossil fuel power generation decline in the next decade. However, despite these huge leaps in progress, most renewable energy solutions still face quite a simple problem.
Put simply, solar panels cannot generate power during the night and wind turbines cannot generate power unless there is wind. This challenge requires the power grid to have other power sources available - often fossil fuel - as back-up.
"The United States alone would want to build more than 100 gigawatts of storage over a decade […] significantly improving reliability and making solar, wind, nuclear, and coal much cheaper to deliver.” McKinsey & Company
These challenges can mean that energy is quite often being wasted by renewable energy plants. For example in China - currently accounting for one third of global installed wind power capacity - curtailment rates in wind generation averaged 15% according to China's Renewable Energy Industries Association (CREIA) - with some areas in China reaching rates of 60%. Matching demand with supply is therefore a hurdle which can be tackled by an efficient and low cost form of energy storage.
Founder and CTO of EnergyNest, Pål G. Bergan, had for a long time been conscious of this issue during his career as an engineer, research director, professor and industrial innovator. He wanted to find a solution that would be low-cost, technically simple and possible to implement anywhere and to all applications. Since 2011, EnergyNest has developed a unique thermal energy storage technology with superior advantages over the current solutions. In collaboration with Heidelberg Cement, a new type of concrete "HEATCRETE®" has been developed and tailored to have the optimum performance with respect to storing thermal energy.
EnergyNest is solving problems in three grid-scale energy storage markets with a combined +$5billion market by 2020:
Concentrated Solar Power (CSP).
- Problem: Storage is the key differentiator of concentrated solar power (CSP) generation. The incumbent technology, storing thermal energy in molten salt, is expensive and poses technical challenges.
- Solution: EnergyNest’s technology is optimally suited to replace molten salt and significantly reduce CAPEX and OPEX for CSP storage. EnergyNest can help to improve the attractiveness of new, as well as existing, CSP power plants
Long-duration power grid storage.
- Problem: Electricity storage can add significant value to power grids in a large variety of use cases. Current battery technologies, mainly Lithium-ion batteries, are expensive, in particular for long-duration storage
- Solution: EnergyNest’s technology can be used as a battery by converting electricity to thermal energy and converting it back to electricity when it is needed. The solution is particularly well suited for long-duration storage with low cost of charging electricity
Industrial waste heat storage.
- Problem: With increasing energy prices, various industries are looking to reduce their energy cost and are looking for solutions to use otherwise wasted energy. We have not identified any viable solution in market.
- EnergyNest offers a versatile solution to overcome the mismatch between supply and demand of heat. Exemplary applications are storage of excess heat for electricity generation (waste heat to power), buffering to increase flexibility of combined cycle gas turbones and many more applications

Our business & market situation
The addressable market for EnergyNest technology is long duration, stationary, utility scale energy storage. If the energy source is thermal already, the sweet spot are uses cases with temperature ranges between 150 - 420°C and more than 4 hours’ of storage duration. If the energy source is electricity, which needs to be converted to heat in order to be stored with EnergyNest technology, the sweet spot for supply of approx. 1-20 MW of electricity and more than 4 hours of charge/discharge duration in a Combined-Heat-Power (CHP) setup.
The energy storage market is expected to grow quite significantly over the next few decades. This can be verified with reports from 3rd party providers. The driving force behind this growth is the expected build out of energy generation from renewable sources, a non-continuous energy supply by nature, and the global efforts to decrease the carbon footprint overall by recycling waste heat.
EnergyNest has thoroughly investigated the market and defined, in collaboration with partners, three target segments for its technology:
- Concentrated Solar Power (CSP): This technology heats up a fluid by a setup of aligned mirrors, and uses the fluid to generate electricity or for industrial purposes. In order to make the power plant economically attractive, a storage is mandatory to ensure continuous supply of energy.
- Power Grid use cases: The tremendous growth in renewables on a global scale is a challenge for the power grid operators and the owners of renewable power generation assets. In many countries (e.g China) the grid capacity is often limited and renewable energy needs to be dumped. Storing excess energy and feeding it into the grid when capacity is available makes the business case for renewables more attractive.
- Industrial applications: In many industrial settings waste heat is generated which can not be avoided and or reused in the industrial process itself. By storing waste heat and using it for generating electricity or heating when needed, the carbon footprint of the industrial setup is improved.
Key market trends across the target segments:
- Concentrated Solar Power (CSP): The market is expected to grow at least by 12% p.a. until 2030. China alone announced in the recent 5y plan 10 GW of new installations by 2020, twice as much as currently is installed on a global basis. Storage attachment rate is anticipated to be at least 80-90% compared to approx. 50% historically. Adding storage of existing facilities without storage is an attractive use case for CSP plant owners with a very short payback.
- Power Grid: The market is expected to grow at least by 20% p.a. until 2030. This is mainly driven by the global ambitions to increase the footprint of renewable energy generation and decrease the footprint of convential energy generation (e.g., coal, nuclear). Since renewable energy generation is not continuous, storage is required to meet energy demand whenever its needed over the day. Another driving force is the grid capacity challenge in many countries (e.g., China, Germany). By storing renewable energy when the grid is congested, the utilization of renewable power generation can be improved significantly.
- Industrial applications: The market is expected to grow more than 10% p.a. until 2030. Driven by the trend to reduce the waste heat inventory, companies are looking for ways to recycle as much as possible of their waste heat to reduce the carbon footprint and the electricity bill.
The Masdar Project
In a joint project with Masdar Institute, EnergyNest has built a pilot facility in Abu Dhabi demonstrating its technology. Masdar has provided the Solar R&D platform in which the pilot from EnergyNest is integrated, and EnergyNest managed the design, installation, commissioning and training of the pilot facility during 2015 with the help through sponsorships from HeidelbergCement, Dow and Siemens. In November 2015 the pilot was finalized and validated by DNV GL. The report from DNV GL confirms that the technology works and all claims with respect to operating temperature, storage capacity and storage efficiency are met. EnergyNest and Masdar Institutes celebrated the inauguration of the pilot together with more than 200 guests in November 2015, and CNN made a small movie about EnergyNest. Currently the pilot is run in a 24x5 mode to demonstrate that there is no degradation in material or other adverse effects when operating the storage. We have now accumulated 1500 hours of operations (status August 2016) and the storage performs perfectly as simulated and without any change in the charge or discharge pattern. The pilot facility also serves as demonstration room and is frequently visited by customers, investors and business partners.
