Swedish heat pump company Qvantum is developing renewable energy sources to shape a more reliable and efficient future for the electricity grid

As society rapidly electrifies, variable renewable energy sources like solar and wind power are playing an increasingly significant role in the energy mix. This shift has contributed to fluctuating electricity prices, necessitating innovative solutions. One way to address the issue is the provision of flexible electricity prices that reflect oversupply and scarcity. If this flexibility is given a value, users of such tariffs can optimise their electricity cost while contributing to a more stable electric grid.

Qvantum, a Swedish heat pump company, offers heat pumps and systems that can benefit from such an opportunity to provide renewable heating and cooling in an economically and ecologically efficient way.

Qvantum’s heat pumps have single family, multi-family and commercial applications. The energy source for the heat pumps is either ambient energy from air, water or ground or excess energy from buildings, sewers, data centres and others. In the case of multi-family buildings, the energy is fed to the heat pump through an ambient loop, also known as energy grid or thermonet. It is a water-based loop connecting many individual heat pumps, one installed in each apartment, providing heating, cooling and hot water to the tenants.

All Qvantum heat pumps use a smart interface and generative AI to provide balancing services to the electric grid. The Qvantum systems store electricity in the form of molecules and can shift demand from times of shortage to times of surplus. Buildings equipped with these systems become active elements in an increasingly decentralised electricity grid powered by renewable energy sources.

Renewable, energy efficient, smart

While high seasonal efficiency remains essential for a good heat pump solution, today’s users also expect economic efficiency. This is achievable with today’s technologies. Heat pumps, using a flexible electric tariff, potentially combined with self-generated electricity from rooftop solar and combined with electric and thermal batteries can optimise the operating hours to optimise cost while maintaining consumer comfort. A smart controller evaluates user behaviour, weather data and comfort expectations and decides when to operate the heat pump to maximise the use of low-price electricity and avoid peak hours.

A fleet of these systems can provide a form of “synthetic inertia,” mimicking the stabilising effect of traditional power plants, which becomes a crucial function as variable renewable energy sources become more prevalent.

During periods of low electricity prices and ample supply, Qvantum’s system can be “overcharged” to store heat at temperatures of up to 90 degrees Celsius, allowing for its later use. Additionally, their inverter-controlled heat pumps allow to maximise technical efficiency. All these functionalities are seamlessly integrated into Qvantum heat pumps. They are not an extra, but part of the standard design.

Collective power: Heat pumps working together

Qvantum’s heat pumps are designed to work collaboratively, either through their own software or via open APIs with third-party solutions. This collaborative approach significantly amplifies their impact. By controlling a swarm of heat pumps, differences of demand can be reduced. Conversely, when renewable energy sources like wind or solar generate excess electricity, Qvantum’s heat pumps can act as buffers, storing the surplus to meet future energy needs. By assisting the grid in managing both peak and low demand periods, these pumps pave the way for a novel electricity economy where individual households and society as a whole benefit from interconnected and efficient energy management.

“Suppose that 1,000 heat pumps are shut down at the same time, we are talking about a reduced power requirement of several megawatts, which makes a big difference for a city with increased electricity. Qvantum’s new heat pump platform is designed for the heat pump to be an active node in the grid that helps the grid and creates more space for renewable energy in the production mix. It is also very profitable for our customers when they allow their heat pumps to become part of the new energy markets for flexibility and frequency stabilisation that are now growing,” says Fredrik Rosenqvist, CEO Qvantum Energy.

Embracing challenges and creating opportunities

Qvantum acknowledges the challenges presented by a transitioning energy landscape but views them as opportunities for innovation. Their commitment to developing smart and sustainable energy solutions positions them as a key player in shaping a more reliable and efficient future for the electricity grid and with the mission to make the energy transition available for the many people.

Forecast methodology

The future outlook “forecast” is based on a set of statistical methods such as regression analysis, industry specific drivers as well as analyst evaluations, as well as analysis of the trends that influence economic outcomes and business decision making.
The Global Economic Model is covering the political environment, the macroeconomic environment, market opportunities, policy towards free enterprise and competition, policy towards foreign investment, foreign trade and exchange controls, taxes, financing, the labour market and infrastructure. We aim update our market forecast to include the latest market developments and trends.

Forecasts, Data modelling and indicator normalisation

Review of independent forecasts for the main macroeconomic variables by the following organizations provide a holistic overview of the range of alternative opinions:

  • Cambridge Econometrics (CE)

  • The Centre for Economic and Business Research (CEBR)

  • Experian Economics (EE)

  • Oxford Economics (OE)

As a result, the reported forecasts derive from different forecasters and may not represent the view of any one forecaster over the whole of the forecast period. These projections provide an indication of what is, in our view most likely to happen, not what it will definitely happen.

Short- and medium-term forecasts are based on a “demand-side” forecasting framework, under the assumption that supply adjusts to meet demand either directly through changes in output or through the depletion of inventories.
Long-term projections rely on a supply-side framework, in which output is determined by the availability of labour and capital equipment and the growth in productivity.
Long-term growth prospects, are impacted by factors including the workforce capabilities, the openness of the economy to trade, the legal framework, fiscal policy, the degree of government regulation.

Direct contribution to GDP
The method for calculating the direct contribution of an industry to GDP, is to measure its ‘gross value added’ (GVA); that is, to calculate the difference between the industry’s total pre­tax revenue and its total bought­in costs (costs excluding wages and salaries).

Forecasts of GDP growth: GDP = CN+IN+GS+NEX

GDP growth estimates take into account:

  • Consumption, expressed as a function of income, wealth, prices and interest rates;

  • Investment as a function of the return on capital and changes in capacity utilization; Government spending as a function of intervention initiatives and state of the economy;

  • Net exports as a function of global economic conditions.

Market Quantification
All relevant markets are quantified utilizing revenue figures for the forecast period. The Compound Annual Growth Rate (CAGR) within each segment is used to measure growth and to extrapolate data when figures are not publicly available.

Revenues

Our market segments reflect major categories and subcategories of the global market, followed by an analysis of statistical data covering national spending and international trade relations and patterns. Market values reflect revenues paid by the final customer / end user to vendors and service providers either directly or through distribution channels, excluding VAT. Local currencies are converted to USD using the yearly average exchange rates of local currencies to the USD for the respective year as provided by the IMF World Economic Outlook Database.

Industry Life Cycle Market Phase

Market phase is determined using factors in the Industry Life Cycle model. The adapted market phase definitions are as follows:

  • Nascent: New market need not yet determined; growth begins increasing toward end of cycle

  • Growth: Growth trajectory picks up; high growth rates

  • Mature: Typically fewer firms than growth phase, as dominant solutions continue to capture the majority of market share and market consolidation occurs, displaying lower growth rates that are typically on par with the general economy

  • Decline: Further market consolidation, rapidly declining growth rates

The Global Economic Model
The Global Economic Model brings together macroeconomic and sectoral forecasts for quantifying the key relationships.

The model is a hybrid statistical model that uses macroeconomic variables and inter-industry linkages to forecast sectoral output. The model is used to forecast not just output, but prices, wages, employment and investment. The principal variables driving the industry model are the components of final demand, which directly or indirectly determine the demand facing each industry. However, other macroeconomic assumptions — in particular exchange rates, as well as world commodity prices — also enter into the equation, as well as other industry specific factors that have been or are expected to impact.

  • Vector Auto Regression (VAR) statistical models capturing the linear interdependencies among multiple time series, are best used for short-term forecasting, whereby shocks to demand will generate economic cycles that can be influenced by fiscal and monetary policy.

  • Dynamic-Stochastic Equilibrium (DSE) models replicate the behaviour of the economy by analyzing the interaction of economic variables, whereby output is determined by supply side factors, such as investment, demographics, labour participation and productivity.

  • Dynamic Econometric Error Correction (DEEC) modelling combines VAR and DSE models by estimating the speed at which a dependent variable returns to its equilibrium after a shock, as well as assessing the impact of a company, industry, new technology, regulation, or market change. DEEC modelling is best suited for forecasting.

Forecasts of GDP growth per capita based on these factors can then be combined with demographic projections to give forecasts for overall GDP growth.
Wherever possible, publicly available data from official sources are used for the latest available year. Qualitative indicators are normalised (on the basis of: Normalised x = (x - Min(x)) / (Max(x) - Min(x)) where Min(x) and Max(x) are, the lowest and highest values for any given indicator respectively) and then aggregated across categories to enable an overall comparison. The normalised value is then transformed into a positive number on a scale of 0 to 100. The weighting assigned to each indicator can be changed to reflect different assumptions about their relative importance.

The principal explanatory variable in each industry’s output equation is the Total Demand variable, encompassing exogenous macroeconomic assumptions, consumer spending and investment, and intermediate demand for goods and services by sectors of the economy for use as inputs in the production of their own goods and services.

Elasticities
Elasticity measures the response of one economic variable to a change in another economic variable, whether the good or service is demanded as an input into a final product or whether it is the final product, and provides insight into the proportional impact of different economic actions and policy decisions.
Demand elasticities measure the change in the quantity demanded of a particular good or service as a result of changes to other economic variables, such as its own price, the price of competing or complementary goods and services, income levels, taxes.
Demand elasticities can be influenced by several factors. Each of these factors, along with the specific characteristics of the product, will interact to determine its overall responsiveness of demand to changes in prices and incomes.
The individual characteristics of a good or service will have an impact, but there are also a number of general factors that will typically affect the sensitivity of demand, such as the availability of substitutes, whereby the elasticity is typically higher the greater the number of available substitutes, as consumers can easily switch between different products.
The degree of necessity. Luxury products and habit forming ones, typically have a higher elasticity.
Proportion of the budget consumed by the item. Products that consume a large portion of the consumer’s budget tend to have greater elasticity.
Elasticities tend to be greater over the long run because consumers have more time to adjust their behaviour.
Finally, if the product or service is an input into a final product then the price elasticity will depend on the price elasticity of the final product, its cost share in the production costs, and the availability of substitutes for that good or service.

Prices
Prices are also forecast using an input-output framework. Input costs have two components; labour costs are driven by wages, while intermediate costs are computed as an input-output weighted aggregate of input sectors’ prices. Employment is a function of output and real sectoral wages, that are forecast as a function of whole economy growth in wages. Investment is forecast as a function of output and aggregate level business investment.
