This document discusses the benefits of using a high duct fired gas turbine combined heat and power (DF-GT-CHP) system compared to a standard package boiler system for industrial steam and power needs. Some key points made:
1) A DF-GT-CHP system can generate both steam and electricity on-site more efficiently than separate steam and power systems. It offers higher overall efficiency across all load levels compared to a package boiler that varies in efficiency.
2) Economic analysis shows the DF-GT-CHP system has lower net operational costs of steam production and can reach operational net zero costs at lower natural gas and power prices compared to a package boiler. It also has shorter payback periods on incremental

The Stirling engine is noted for its high efficiency compared to steam engines, quiet operation, and the ease with which it can use almost any heat source.This engine is currently exciting interest as the core component of micro combined heat and power (CHP) units, in which it is more efficient and safer than a comparable steam engine.

This paper examines the critical role of Human Resources in ensuring the long-term success
and sustainability of the steel industry in a rapidly changing world. It provides an in-depth look into
best practices and strategies for building a future-ready HR function and outlines the steps organizations
can take to future-proof their HR strategies. As the industry faces new challenges, HR practices enabled
with digital tools can be adapted to address these challenges and ensure that organizations are equipped
to thrive in the future. Moreover, HR plays a pivotal role in developing future-ready skills and building
a strong culture that supports adaptability and growth. With the advent of Industry 4.0, digital
transformation has become essential for bringing about a competitive advantage to steel makers. To
leverage these I4.0 tools, the need for their acceptability among the employees is paramount for driving
sustainable value unlocking. Human resource management in steel plants will not only have to work to
bridge the skill gap with respect to Industry 4.0, but also will have to act as a digital culture builder
within the organization. This paper discusses how HR can leverage its digital face to trigger this cultural
transformation and work on organizational capacity building. Additionally, the paper delves into the
evolved role of Digital HR in the challenging scenario. To corroborate the understanding, a use case of
the success story of digital HR-enabled digital transformation at Tata Steel has been provided in the
subsequent section. Overall, this paper aims to provide a roadmap for organizations in the steel industry
to leverage their human resources as a key driver of success and resilience in the face of uncertainty.
By utilizing the best practices and strategies outlined in this paper, organizations can ensure that their
HR functions are future-proofed and equipped to handle the ever-changing landscape of the steel
industry.

Additional DF GT‐CHP benefits compared to standard package boiler systems.
Benefit to Grid
Local grid stability including power factor support and reduced I2R line loss
Balance variable power from wind and solar, thus speed renewable energy deployment
Defer or avoid investment in
Remote central generation plants
Transmission & Distribution infrastructure
Benefit to the thermal host
Reduced cost of steam and increased steam supply reliability
More reliable power supply
Benefit to society
Reduced pollution and lower greenhouse gas emissions
Efficiency equals “free fuel”

Inertia and unfamiliarity
Standard compliance solutions seen as “tried and true”
Energy Policy Act, 2005
Hurts ability of regulated utilities to secure certain cost recovery for long‐term Power Purchase Agreements (PPA) with CHP plants.
Makes CHP plant financing difficult
Air permit
MACT pollution control regulations allow retaining current air permit.
CHP reduces pollution, yet requires a new permit
Standby & exit charges
Imposed by some utilities before allowing CHP systems to interconnect with the grid.
Upfront investment
Greater upfront CapEx required.
Hurdles facing natural gas fired GT‐CHP
Too many people expend too much effort to avoid the effort of thinking.
Why mess with “tried & true”?

Project development: common sense and diligence
1. Set objectives & gather data
2. Conceptualize alternate configurations: Technical & economic appraisal
3. Project development
Technical: Configuration, engineering, procurement, construction
Legal: Structure of contracting entities (LLC, S or C Corp etc…)
Commercial: Contracts for fuel, power, O&M, grants & incentives
Environmental: Permits
Financial: Financial models, equity & debt
Risks & Mitigants: Project Execution Plan (PEP)
