The central idea
How does electricity connect to the entire energy system?
Electricity becomes the coordinating carrier of a low-carbon system, but efficient integration depends on heat, molecules, mobility, storage, networks and flexible demand, not electrification at any cost.
Electricity becomes the coordinating carrier of a low-carbon system, but efficient integration depends on heat, molecules, mobility, storage, networks and flexible demand, not electrification at any cost. The public preview explains the operating logic, professional relevance and boundaries before the complete guided application.
Professional relevance
Why this matters beyond the classroom.
Hook: One MWh can produce radically different outcomes. Hook: Losses multiply. Hook: Security infrastructure can become transition exposure.
What you will learn
Four lessons that build one working mental model.
- 01
Energy Carriers, Services and Conversion
Primary energy, carriers, useful energy, efficiency, exergy, direct and indirect electrification.
People and firms do not demand energy for its own sake. They demand warm rooms, mobility, light, mechanical work, data, high-temperature heat and chemical products. The same service can be delivered through different carriers and conversion chains. An integrated analysis begins with useful service, then works backward. How many passenger-kilometres, tonnes of steel, cubic metres of hot water or hours of thermal comfort are required? At which location and time? With what quality, reliability and temperature? This prevents false comparisons. One MWh of electricity can power an efficient motor, a resistance heater, a heat pump or an electrolyser, producing very different useful outputs. Carrier totals alone do not capture quality or system value. Primary sources include wind, sunlight, hydro, biomass, geothermal, uranium and fossil resources. Carriers, electricity, hydrogen, methane, heat and liquid fuels, move or store energy. End-use technologies convert carriers into services. Electricity is a high-quality carrier: versatile, controllable and efficient at point of use. It is difficult to store seasonally at large scale without conversion or specialised storage. Gases and liquids are easier to stockpile and useful for molecules, high-temperature processes and transport, but their conversion can be less efficient.
- 02
Gas, Heat and Hydrogen
Natural gas/LNG chains, district heat, heat pumps, hydrogen, electrolysers and Power-to-X.
District heating distributes hot water or steam from central or multiple sources. Sources can include CHP, large heat pumps, geothermal, solar thermal, biomass, waste heat and thermal storage. Lower network temperatures can reduce loss and accept more low-grade heat. Economics depend on demand density, pipe cost, heat loss, source durability and customer connection. Networks are local monopolies requiring tariff, consumer and investment governance. A cheap waste-heat source is not bankable if the industrial host can close. Thermal storage decouples heat production and demand. Large water tanks or pits can shift hours, days or seasons depending on design, often at lower cost than storing equivalent electricity. Combined heat and power produces useful heat and electricity from one fuel. Efficiency is high only when heat is genuinely useful. In a renewable-heavy system, inflexible heat-led CHP electricity can coincide with low/negative prices. Gas CHP retains combustion emissions; biomass requires sustainable feedstock and air-quality control. Future operation may become flexible, using thermal storage to choose electricity hours. Large heat pumps and waste heat can compete. Evaluate marginal emissions and opportunity cost, not total efficiency alone. The counterfactual heat and power sources determine benefit. Hydrogen.
- 03
Electrified Demand and Flexibility
EVs, industry, flexible loads, demand response, storage durations and digital coordination.
Industry uses electricity for motors, pumps, compressors and increasingly heat. Options include resistance, induction, infrared, microwave, electric arc, plasma and industrial heat pumps. Process redesign can reduce energy and improve product quality. Technical feasibility depends on temperature, heat transfer, duty cycle, product chemistry, reliability and retrofit constraints. Economics depend on electricity versus fuel price, carbon, network charge, CAPEX, utilisation and downtime. Electrification can create large concentrated loads with long grid lead times. Flexible production, thermal buffers and hybrid equipment can support the system, but product delivery and safety limit response. Industrial policy, grid planning and contracts must coordinate. Some sectors need hydrogen as a molecule, not merely heat. Ammonia synthesis uses hydrogen feedstock. Direct-reduced iron can use hydrogen to remove oxygen from iron ore. Refining already consumes hydrogen. These uses may have stronger rationale than burning hydrogen for low-temperature heat. But conversion requires new equipment, high-quality supply, storage, infrastructure and competitive product markets. Leakage and NOx from combustion require attention. Contracts can index hydrogen to electricity, gas, carbon or product prices. Long-term offtake helps finance production but transfers volume and policy risk. Demand response changes consumption relative to a baseline.
- 04
Integrated Planning and Business Models
Cross-vector infrastructure, hourly/seasonal models, markets, regulation, resilience and investment choices.
Integrated assets combine revenue: electrolyser hydrogen plus flexibility; battery arbitrage plus balancing; CHP heat plus power; EV aggregator capacity plus charging service. Stacking can improve utilisation but services may conflict. Build an availability matrix by interval. If a battery reserves discharge for capacity, those MWh cannot also be sold earlier. If an electrolyser must meet hydrogen offtake, curtailment flexibility may be limited. Contracts set priority and penalties. Avoid counting system benefit as private revenue unless a market or contract pays it. Congestion relief has value but may need procurement or regulated treatment. Direct emissions occur at combustion or process. Indirect electricity emissions depend on accounting purpose: average grid, marginal system impact, contractual attributes or regulatory methodology. Lifecycle adds construction, fuel supply, methane leakage and disposal. For flexible electrolysis or EV charging, timing affects marginal emissions. Annual renewable certificates may not prove hourly physical matching. Regulatory renewable-hydrogen rules define their own criteria. State both metric and boundary. Do not add avoided emissions from heat, transport and electricity if they arise from the same renewable MWh more than once. Integrated systems share resources during normal operation but can propagate failures. Cold weather.
Key takeaways
What should remain after the details.
- Services determine suitable routes.
- Sequential losses multiply.
- The physical state enables shipping.
- COP varies.
- Production and lifecycle matter.
- Rare operation can raise unit cost.
- But feasibility still matters.
- Availability must be evidenced.
Correct the shortcut
Common misconceptions
- Treating begin with useful service as an isolated label
- Hook: One MWh can produce radically different outcomes.
- Treating follow every conversion as an isolated label
- Hook: Losses multiply.
- Treating gas, lng and heat as an isolated label
- Hook: Security infrastructure can become transition exposure.
- Treating heat-pump and district-heat lab as an isolated label
- Hook: COP 3 turns one electric MWh into three thermal MWh.
- Treating hydrogen and power-to-x as an isolated label
- Hook: Hydrogen is made, not mined as a clean primary source.
Worked reasoning
Electrolyser business case
Electricity often dominates variable cost. At €50/MWh and 52 kWh/kg, electricity alone costs €2.60/kg. Add network charges, water, O&M, compression, CAPEX recovery and financing. Oxygen or heat revenue should be credited only with a real customer and delivery cost. Bankability requires electricity supply, grid capacity, renewable compliance, offtake volume/price/credit, technology guarantees, construction and transport/storage. Matching intermittent generation with continuous industrial demand may need grid supply, storage or flexible process. The electrolyser can provide demand flexibility, but cannot simultaneously maximise hydrogen delivery and turn off whenever power prices rise. Contracting must allocate this opportunity cost.
