Hydropower, Geothermal, and Ocean Energy: Traditional and Emerging Sources

Energy Transition and Renewable Energy October 25, 2025
Enquire About This Course

Introduction

While solar and wind receive much attention, the baseload, dispatchable, and continuous potential of other renewables—hydropower, geothermal, and ocean energy—remains critical to a stable energy system. This course provides a comprehensive technical and environmental examination of these established and emerging power sources. Participants will analyze the design complexities of various systems, from large-scale dams to deep-earth drilling and tidal turbines. The program focuses on assessing the resource availability, mitigating environmental and social impacts, and understanding the role these non-intermittent sources play in achieving global decarbonization goals.

Objectives

Upon successful completion of this program, participants will be able to:

  • Differentiate between conventional, run-of-river, and pumped storage hydropower and their operational profiles.
  • Explain the thermodynamic principles and resource requirements for various types of geothermal power plants.
  • Assess the technical viability and resource predictability of tidal stream and wave energy technologies.
  • Conduct a preliminary environmental and social impact assessment for major water and land-based energy projects.
  • Analyze the unique role of these sources in providing dispatchable, baseload power to the grid.
  • Understand the regulatory and permitting complexities specific to geothermal and ocean energy exploration.
  • Evaluate the economic trade-offs and financing structures for these long-life, high-CAPEX assets.
  • Formulate a strategic rationale for integrating these reliable sources into a national energy mix.

Target Audience

  • Hydropower and Civil Engineers
  • Geothermal Resource Geologists and Drilling Engineers
  • Ocean Energy Developers and Maritime Specialists
  • Environmental and Social Impact Assessors
  • Energy Infrastructure Planners and Regulators
  • Investment Analysts specializing in baseload renewables
  • Utility Engineers and System Planners

Methodology

  • **Scenarios:** Conducting a preliminary environmental risk assessment for a proposed tidal stream power project in a sensitive estuary.
  • **Case Studies:** Analyzing the successful development and subsequent environmental challenges of a major hydropower complex.
  • **Group Activities:** Collaboratively determining the best geothermal power plant type (flash vs. binary) for a resource with specific temperature and fluid characteristics.
  • **Individual Exercises:** Mapping the required permits and regulatory steps for a new Enhanced Geothermal System (EGS) drilling project.
  • **Mini-Case Studies:** Rapid evaluation of a new wave energy converter technology for its technical feasibility and grid compatibility.
  • **Syndicate Discussions:** Debating the ethical trade-offs between the environmental impact of large hydropower versus its role in grid stability.
  • **Resource Assessment:** Analyzing seismic data (conceptual) to identify a high-potential geothermal exploration target.

Personal Impact

  • Acquisition of specialized knowledge in high-CAPEX, long-life renewable assets.
  • Improved ability to conduct complex environmental and social risk assessments.
  • Enhanced expertise in non-intermittent, dispatchable power generation technologies.
  • Positioning for roles in utility planning, infrastructure, and resource extraction.
  • Mastery of the unique engineering and geological challenges of these systems.
  • Increased confidence in managing projects with long permitting and development timelines.

Organizational Impact

  • Reduced operational risk through integration of reliable, baseload generation assets.
  • Improved organizational capacity to manage complex, multi-stakeholder infrastructure projects.
  • Enhanced grid stability and resilience by minimizing reliance on weather-dependent sources.
  • Compliance with stringent environmental and social governance (ESG) standards.
  • Access to niche international markets for geothermal and ocean energy development.
  • Long-term energy security through stable, locally available resources.

Course Outline

Unit 1: Hydropower Fundamentals and Systems

From Baseload to Flexibility
  • Operating principles of conventional impoundment, diversion, and pumped storage.
  • Detailed analysis of dam design, civil engineering, and structural integrity.
  • Managing reservoir operations for power, flood control, and water supply.
  • The environmental and social impacts of large-scale dam projects (sedimentation, displacement).
  • Modernizing existing hydropower assets for enhanced grid flexibility and black-start capability.

Unit 2: Geothermal Energy Exploration and Power

Tapping Sub-Surface Heat
  • Geothermal resource types: hydrothermal, enhanced geothermal systems (EGS), and co-produced.
  • Operating principles of dry steam, flash, and binary cycle power plants.
  • Resource exploration techniques, reservoir modeling, and drilling technologies.
  • Managing the environmental risks: seismicity, non-condensable gases, and water use.
  • The economics of geothermal, characterized by high CAPEX and low OPEX.

Unit 3: Ocean Energy: Tidal and Wave

Harnessing the Blue Economy
  • Tidal range technologies: tidal barrages and their environmental impact.
  • Tidal stream current technologies and resource assessment.
  • Principles of wave energy conversion (WECs) and their various devices (point absorbers, attenuators).
  • The technical and logistical challenges of deploying and maintaining subsea energy devices.
  • Regulatory and maritime policy frameworks for ocean energy development.

Unit 4: Environmental and Social Governance

Managing Long-Term Impacts
  • Advanced techniques for assessing ecosystem and biodiversity impacts (fish passage, sediment flow).
  • Engaging with local communities and indigenous populations (Free, Prior, and Informed Consent - FPIC).
  • Designing mitigation strategies for noise, visual, and ecological disturbances.
  • The long-term decommissioning and remediation requirements for these assets.
  • Integrating ESG standards into project development and financing.

Unit 5: Market Integration and Future Potential

The Role in Grid Stability
  • Modeling the dispatchable nature of hydro and geothermal in power systems.
  • Hybridizing these sources with intermittent renewables (e.g., pumped hydro with wind).
  • Cost trends, technological readiness levels (TRL), and global deployment potential.
  • Policy and regulatory incentives necessary to scale up ocean and EGS technologies.
  • Strategic comparison of LCOE and LCOS for these baseload alternatives.
